Before we start you need to look at yourself if you need to tell me that old processors aren't as fast as newer ones. I have 2 lenovo A70 systems they're old but have 4gb ram each, theyre towers with PCIE support so very modular, run cool and quiet, support windows 10 & 11(microsoft have issues) and have gigabit ethernet. There is enough here for a decent desktop experience but modern games, some productivity software and WEB BROWSERS will choke on this budget pentium cpu as well as windows 10 background tasks. The one thing I wont attempt is using old storage when basic SSDs are so cheap, the system supports sata 2 which is plenty for a responsive system. Theres a Kioxia 240gb ssd dangling in the below photo but it will be getting a 3d printed bracket. E5800 pentium performance in 2023 The system was really unresponsive with 90% or 100% cpu utilisation browsing the web. The geekbench score of 382 single core and 618 multicore nails the performance issue here. The mod Its possible to use old xeon 771 chips in core 2 duo/quad era motherboards often going from single/dual core 65nm chips to full blown 45m quad core chips that can overclock to 4ghz. The mod requires a bios patched with xeon microcodes, a taped sticker on the cpu pins and either the motherboard alignment pins cut out with a 18mm snap off knife or pre modded cpu from china. As I already own an x5460 I found premodded bios files for my system and flashed them via windows. This youtuber modded the bios, I tried to do patch myself but couldnt get the patcher to recognise a current Lenovo .rom file. Install As I was feeling traditional after dissaseembly I dropped my new cpu onto the socket pins. Using a microscope and steel soldering tweezers the one bent pin got mostly bent back. A cmos reset was required without it posted but wouldnt get to windows. Cmos reset by removing the CR2032, unplugging hdmi and mains cable then holding the power button. Cooling Its really obvious that this system needed new thermal paste on the cpu, northbridge, southbridge and gpu but I think we forget how bad modern cooling can be. Even though the system came with only a 65w pentium chip the system still came as standard with a bulky aluminium heatsink and thick modular fan and fully supports my 120w xeon cpu. The experience Using this system is night and day better its so much more responsive and doesnt get become unresponsive from windows update or anti virus scans. Browsing the internet is responsive and video playback works in HD. Booting the computer is much faster with 16.4 seconds to the windows login screen or 20 seconds to desktop. The new geekbench score with a 10.7% imrovement in single core performance thanks to the extra cache on the premium xeon and 90% improvement in multicore performance. The caveat The old geforce 8400 graphics card is lacking while its got some video accleration in the form of 'second generation PureVideo HD' for h264 which DOES improve playback in vlc, youtube uses vp9 and seems to be moving back to that from av1, while I can playback 4k30 content at 84% utilisation its not a zero impact thing like on a 12th gen system with vp9 acceleration. Alternatives The 3.16ghz xeon x5460 is about the best cpu you can expect to pickup at a reasonable price but other options like the intel 2.8ghz q9505, q9500 and q9550 or 2.66ghz q9400 share a similar used price and cache and if you're using a non oem mobo its not unreasonable to overclock those cpus to well beyond the 3.16ghz I achieved. Yes its easy to pickup better samples but its the used market and depends on your area. Lenovo_ThinkCentre A70_L-IG41M2_BIOS_MOD.zip

is the performance between these chips significant? ( E5450 vs E5440 || X5450 vs X5440 ) which one would you suggest?(please include Reasoning) Specs: 6gb of ddr2 (kvr800) P43 neo-F Deepcool ice edge 200T R5 240 1gb ddr3 (hd 8570)

I want to do a build with the lga 771 to 775 mod. I like the x5460 and i want to know one or a few compatible motherboards, been looking for answers.

Right so ive got an Asus striker 2 Formula wich is a 780i chipset board and its great, unfortunatly the C2Q aren't for their price so i want to put an x5460 in it with the 771 to 775 mod now what i want to know is will the board support it straight away. the reason i ask is because on the mods site i cant remember what it is but its pretty much where the whole 771 to 775 thing started and anyway they have a chart showing what chipsets will work with what C2D, C2Q and Xeons. My board being a 780i chipset is compatible with all C2Q and thus the x5*** series of Xeons but ive read that some boards will need a custom bios flashed for it to work and some dont. i really dont want to do a bios flash if i dont need to so if someone could give a definite answer that would be great also if i do need one if somebody could give me a link to a TRUSTWORTHY bios for this board with the X5460 support that would be awesome. Thanks guys

I have bought and installed xeon x5450 on my gigabyte motherboard that is originally 775 socket. After following a guide and putting a sticker on my processor and assembling the computer, i noticed it won't launch windows installer. I have a new ssd and only RAM and motherboard are from the old PC but it won't show me anything other than blue windows logo. BIOS detects and recognizes xeon, but i still can't install windows on my PC. Is there a way i can get past this problem and have a working machine or am I doomed to stick to my old CPU? Thanks in advance

I recently got a used evga nforce 790i and looking to put a good cpu in it, I wanted to get a core 2 quad q9650 but being $150 or up its out of my price range. the Xeon e5650 is the same processor just as a 771 socket and only cost $20-$30. So I'm curious if my mobo will support the mod and if not what's the next best cpu I can get.

A couple of months ago I put together a test bench that I could use for testing old hardware from my eBay business. It consisted of a Pentium 4@2.66Ghz, 2GB of DDR RAM and an Nvida FX 5200 graphics card. It was pretty crap, but all the parts came in a joblot so I just had to slot everything in and I was good to go. Here's a picture of it if you're interested (WinXP ftw): However last month I decided to give it an upgrade, so I bought a cheap 775 motherboard off eBay that came with a dual core CPU (It was nothing special, just a cheap foxconn board and a pentium dual core). When I bought that motherboard I remembered watching a video about a 771 to 775 mod that allowed you to use some of the older Xeon CPUs in consumer 775 motherboards, and I had the intention of replacing the pentium with a quad core Xeon later down the line. In the end though I ended up buying the Xeon (an X5450) and the converter sticker on the same day. When all the parts arrived it didn't take long to put it all together. The most nerve-racking part was cutting the tabs on the CPU socket so that the Xeon would fit. It took me a couple of tries but eventually I cut enough off (A quick tip if you plan on doing this mod is to buy a cheap 775 CPU (I just used the pentium dual core) to use as a guide, so if you do screw up all you risk losing it a cheap CPU). After putting the converter sticker on the CPU (The mod requires a sticker to short some pins on the CPU for it to work), I slotted it in the motherboard, put on the cooler and... it didn't boot. I proceeded to waste several hours wondering why (I even brought in a projector from the other room and had that set up as it was the only other portable display I had that had VGA), but eventually I found out that it was my own stupidity. I had put the sticker on upside down - *facepalm*. So after putting on a new sticker the right way round (Thank god I bought two), the system booted up! (Yay). Currently It's still just sitting on a motherboard box, but I plan to get/make a test-bench case at some point in the future. Here's the full spec list if you're interested: CPU: Intel Xeon X5450 GPU: Whatever's lying around, currently an Nvidia 6200LE RAM: 1.5GB of DDR2 (I desperately need to buy more RAM) Motherboard: Foxconn G31MXP 775 Motherboard PSU: Generic Dell 250W Power Supply HDD: 80GB IDE Maxtor Hard drive (I'm gonna get an SSD at some point, this was just the only drive I had at the time) OS: Windows 7 Other: There's a sound blaster card in there at the moment, but I was just testing that out. And here's some pictures: So yeah, that's my testbench. It's pretty bad, and the cabling is a mess (Not much I can really do about that atm, and the PSU has really short cables so it's hard to manage them at all), but it does what I need it to do. The main things I want to do to it next are: Buy an SSD Get more RAM Change the GPU Buy a new power supply Change the motherboard Anyway, if you read this far, then thanks for taking a look! I'd love hear your feedback and also to see your test-benches (I'm sure they're better than mine)

So I have an older Pentium 4 HT PC I got from someone, and I got to wondering if it's possible to use it as a 771 Xeon build instead? It's a prebuilt computer so I don't know the motherboard type or anything off the top of my head, but with a Pentium 4 HT and a Windows Vista original OS, I wondered if it's possible to use a quad core Xeon, or how I would go about finding one that would work? I'm not too worried about the actual mod (I can use the P4 to protect the pins while I use an art knife to cut the guides, and get the sticker needed) but I just don't know how the compatibility works out with this stuff. Never really modded anything like this before and I figured this was a good, CHEAP way to do so. Thanks in advance

Hello! I tried to mod my motherboard (HP Ipiel-la3 https://support.hp.com/us-en/document/c01746799) so it could take a faster LGA 771 Xeon, even though it is LGA 775. This did not work out, but that is mostlikely because I did not install the microcode for the Xeon. Before I waste all of my thermal paste, has anybody ever owned this motherboard and modded it? I highly doubt it, but it is worth the ask.

I am going to buy Dell PowerEdge 2950 server from this website http://www.kvantservice.com/Sarvari_detaili/Artikul_11699_PowerEdge+2950.html I will put 15TB of drives in raid in it and place 64gigs of ram instead of 32.The only concern i have is that the processors are very weak.My question is what are the best performing processors on the socket of the server(lga771) that i can place in the server and will work. I don't care about the price of the cpus too much.I just want them to be at least farely powerful.

Please help guys and girls! I need a decent quiet cooler for a dual lga 771 setup. Cant get one anywhere! Only thing I have found is a thermaltake hr 01x but only place to buy was a south African website that does not ship internationally! Any help at all will be amazing because I'm out of options

A friend of mine has a pc and asked me if I could upgrade it for him. He uses the 775 platform and I found 2 CPUs that would really benefit him. It's either a x5450 for €15,80 quad core 3 ghz or a e5420 quad core 2.5 ghz for €10,81. What would be the best value? They're already 775 modified.

In the LAN PC right now there is a Q6600 which i have yet to overclock so i wont do this for a while but im just wondering what the best Xeons to do the LGA 771 to LGA 775 mod are, im slightly worried that this Q6600 will be a big bottleneck for the dual GTX 660s im putting in it(tho all i play is CS:GO...) so i want to know what the absolute best Xeon for this is and also what some good preformance/$ ones because i have no clue at all tbh and i should probably just swap the motherboard and CPU for some I5 and fitting mobo tbh but i want to try this 771 to 775 thing because its cool and i want to try it some time in the future. anyway thanks for any replies and any help

So, I am planning to upgrade my CPU on LGA775 motherboard (ASRock P5B-DE). After some research I have found out, that you can put LGA771 Xeons in LGA775 sockets, with some modification. Currently, I have Q9400 and want to upgrade to E54xx or X54xx CPU. I looked some videos on YouTube how to make it work. I managed to do everything, except patching new BIOS to work with xeons. It says this: ERROR!! ROM space isn't enough.. There are some old patches that are from 2005 and older. Maybe I can delete those to free up some space. I think that these patches are for Pentium D or Celeron's so they are pretty useless anyway. Maybe anyone of you have tried upgrading like me, and can help me?

So hello I just needed somehelp I wanted to upgrade my media pc which had a dualcore 775 rig, i saw the 775 to 771 mod and bought myself a xeon x5430 along with adapters. I had already cut the socket's hatches and made sure the sticker is in fine position. I updated the bios rom and reseted the cmos ,but whenever i try to power on with the xeon , my computer outputs no display and it turns off after 20-25 seconds. There are no bent pins too, i can work with the previous e8400. Motherboard is ASUS P5gc mx/gbl 2 x2gigs 667 mhz Samsung RAM GTX650Ti Coolermaster 450W PSU x5430/e8400 Any help? And yes , my motherboard can run qx9650 and 9500 from the c2q branch ,so the xeon would work.

Ok so i have a 8800GT and a 250GB HDD laying around that i want to use for a LAN box to run CS:GO at 1080p 60Hz(or there about 720p is fine) but i need a motherboard and a CPU too, so i have decided to try to get a 771 Xeon and modding it to 775 and then try to pick up a 775 board. i know how to do the mod but i dont know what CPU or motherboard to get and i dont know where to get them because Sweden is a total bitch for used parts if you live in the north and you dont have a car... so some help here would be great, also if you happen to have something like a Q6600(or a Q9xxx) and a 775 mobo and you live in Sweden feel free to sell it too me lol. thanks for any replies and any help

Hello and welcome to my guide for performing the LGA 771 mod on your Dell Vostro 220(s) tower. In this guide I will explain the process of preforming the LGA 771 mod on the Dell Vostro 220, specifically focusing on the process of modding a bios and flashing a modded bios. Disclaimer: I am not responsible for any damage to you/your equipment, proceed at your own risk. Tested Systems: Dell Vostro 220 with G45M03 motherboard revision A00 and A03. Note: I have only tested this mod on the Vostro 220, not on the 220s, if you have a 220s and you successfully followed my guide; please let me know so I can add the 220s here EDIT 29/05/17: Confirmed in the 220s (board rev. A00) working by @xpentor STEP ONE: Follow this great guide by @harrynowl to prepare your socket and CPU for the LGA 771 mod. This is 100% necessary to get your CPU to physically fit in the LGA 775 socket, come back when you are ready! If you have completed the guide successfully your CPU and your CPU socket should look like this: NOTE: You might want to edit and flash your bios with your old CPU if windows will not boot with your new LGA 771 CPU (as it did for me). STEP TWO: Download and extract the following files, we will need them later. STEP THREE: To know which microcode to update, you have to know your CPUID. To find your CPUID you can go to http://www.cpu-world.com/ and search your CPU model number (e.g. E5420) in the top right corner. When you have found the page for your CPU (e.g. E5420), scroll down to "CPUIDs" under "Architecture / Microarchitecture". Select the correct CPUID by identifying the S-Spec number of your CPU, the S-Spec Number can be found written on the IHS (integrated hat spreader) of your CPU. For my CPU, a Xeon E5420 S-Spec SLBBL, the CPUID is 1067A. STEP FOUR: Open MMTOOL and load your BIOS rom file. Go to the CPU PATCH tab and Browse for your microcode patch file. The microcodes can be found the desktop-LGA-771-775-microcode.zip file you have downloaded earlier. You want to insert both of the microcode files that begin with your CPUID. For my E5420 with the 1067A CPUID, I want to insert CPU0001067a_plat00000011_ver00000a0b_date20100928.bin and CPU0001067a_plat00000044_ver00000a0b_date20100928.bin. NOTE: You have to add platform type 4, 40 or 44 (plat000000XX) microcodes for your lga 771 xeon to work, these are the only microcode that are for lga 771 xeons. STEP FIVE: We now have to flash the modded bios using AFUWIN. Open the 32bit or 64bit version of AFUWIN depending on your OS configuration. Open your modded BIOS file, and under the "Setup" tab, "Block Options", select "Program All Blocks". Then click "Flash". Now, shut down your computer. When you have shut down your computer, you want to clear the CMOS. NOTE: Clearing the CMOS will reset all bios settings including the time and date. From the Dell Vostro 420/220/220s Manual: When you have reset the CMOS, you want to enter the BIOS and load deafault settings. STEP SIX (optional): While I did not have to do this for my E5420 in my 220, @xpentor reported that disabling SpeedStep was necessary for the mod to work with a E5450 installed in his 220s. STEP SEVEN: Make sure you have competed all steps 1-5 and that your LGA 771 CPU is properly installed. Your new LGA 771 Xeon CPU should now work flawlessly in your Dell Vostro 220(s) tower. If you have any comments or questions please reply below and I will try to respond as quickly as I can

Hey! After seeing the brutally cheap computer Linus build with old serverhardware I wanted to do it but build a home server. I got hold of 2 xeon cpu 4core, motherboard and RAM. I now wonder if you have any tips for the CPU cooling. Socket is 771 but I'm all for modding. The keyword is cheap. So far i spend 1000sek (100euro) and I would like it to be as cheap as possible cause I'm a student ATM. So, can I just buy two cheap heatsinks and mod it on with sipties? Sorry for the bad spelling, I'm Swedish Here is the motherboard: http://www.supermicro.com/products/motherboard/Xeon1333/5000P/X7DBP-i.cfm Best Regards!

So right now I have a Dell Presicion 490 which has the dual socket LGA 771 motherboard. Updated bios, 4gb DDR2 ECC Ram. It booted perfectly to windows 10 with the two Xeon 5160's in it. Now my issue is when I bought two newer Xeon X5460's, which are compatible with this board. Right as I plug in the computer it starts up, zero beeps, no boot, and shows the solid code on the front 3 4. On Dell's manual for that computer shows that it is sleeping and use the mouse or keyboard to wake it. Definitly did not work. What should I do about fixing this?

ok, I'm not rich here, and allthough some of the builds I'm seeing are awesome, your out of my league on most of it. I'm a bit of a gamer, hobbyist, not die hard got to have the best, fastest thing out there. My goal, was to be able to play star citizen, you know the new game thats being crowd funded that everyone in space is talking about, well anyways, my old dell with win XP 32 bit didn't srand a chance. I know. so here's what I did, I found an old server board on e-bay for $100. woo hoo, lucky me. the board sucked, but the duel xeon 5450 processors were great, came with heat sinks and fans too. even the ram had a fan rigged on it. nice haul. well anyways, later i found a better mobo that used all the same hardware. an ASUS DSEB-DG mobo that capable of running duel GPU's sweet huh. at the moment my rig consists of a Rosewill case big enough to house this extended ATX mobo, a Rosewill 1300 lightning 80 plus gold PSU, duel xeon 5450's, 24GB ddr-2 667mhz ram (4X4GB and 4X2GB) ASUS HD6870 GPU, (so far just one), a Renesas D720201 usb 3.0 pci-e adapter, 1TB western digitial green HD, and a sound blaster sound card seems the mobo doesn't have sound. I got all of this for less than $500 so far and really don't want ot spend just too much more. I want to play star citizen, and so far I'm able too, but only on the lowest graphics setting. so it's mission accomplished. well sort of. I do plan on getting a second HD6870 GPU. I can pick oune up in good used cond. for around $100 My big question to all you geeks out there is, what can I do to improve my gaming experience with this rig? how new of GPU's can I put in there and actually benifit from it, I was thinking a set of R9 290's would be quite awesome, but I'd have more money in just the gpu's than i do my whole build. YUK!!! since I'm running a server board is there still a magical over clocking that i could use? how much performance should i expect if I just get the second HD6870? how much performance should I expect if I get the ddr-2 800mhz ram? since this particular mobo can utilize it? how much performance should I expect if I upgrade to an SSD? on sata 2.0 or usb 3.0? besides, going out and blowing $1000 on new mobo, ram, CPU's what can I do to get the biggest bang for the buck in this system I've built. It seems quite stable, and really doing good. I've got a really nice case, and PSU which should last me quite a while no matter what mobo, CPU, GPU configuration i end up decideing to go with down the road. but for now, I'd like to get this thing cranking out as best as I can, would like to play Star citizen on at the very least medium graphics setting with a 30+ frame rate. right now I'm seeing around a 30 frame rate on the lowest setting. would the second GPU push me over and above the 30+ mark on the medium setting, or will I need to seriously concider the 800mhz ram? so far this system is going to have many of the modern conveniences, full usb 3.0 support, possibly a SSD booting in raid zero down the road somewhere. some time later i may stumble across a nice modern mobo, with a more recent generation of CPU and RAM configuration. but buying new is just totally out of the question. I do not have an income to speak of, so I work with what I got, but I'd like a little help in tuning it in to get all that that it is capable of.
