Heavy CPU bottleneck

[Curesto]

I just wanted to show some very heavy CPU bottleneck i had with this system. I have never seen something like this before. CPU %100 usage, GPU %1. Getting like 7-10 FPS on avarage

 

 

System if anyone's wondering:

CPU: Intel Core 2 Duo E6550 running at 1.4GHz

Motherboard: ASUS P5LD2-X

RAM: Kingston 2*2GB DDR2 800MHz

GPU: Sapphire Radeon R9 280X Toxic

OS: Windows 10 Home 64-Bit

 

Game: GTA V, settings are 1920x1080 High everything MSAA X2 AF X16

well first of all turn this down to get maybe 30 FPS

I did it for fun to see what 2007 dual core CPU going to do at these settings.

Also like a CPU upgrade is like https://www.amazon.com/Intel-Extreme-Quad-Core-Processor-1600MHz/dp/B00143O62K

How does it do when you aren't underclocking the CPU?

 

I'd be curious to know how a maxed out E6550 would fair in this situation. I'd imagine it still is a bottleneck for a 280X, but not quite this severe of one. I think you'd probably need at least a Core 2 Quad on that system to max out that GPU in GTA V - but I could be mistaken.

The motherboard is problematic it can't go more than 800 MHz FSB for some reason, E6550 at it's stock clock would be faster to maybe get 20 FPS.

 

A Q9650 or a Xeon X5450 is much faster than these Core 2 Duos. A Xeon X5450 can max out a R9 280X in GTA V. I have that CPU.

 

Here's results with Xeon X5450, which is equal to Core 2 Quad Q9650:

Almost any CPU is a CPU bottleneck but a 7950x3D/13900k. This situation is pretty obvious with an ancient core 2 duo or a Xeon for gaming in 2023.

 

I bet if I down configure my 7950x3D to a 1c/2t and capped the multiplier at 14x I'd likely get similar results with an RTX 4090. Windows 10 on a dual core or 1.4GHz is going to be miserable, regardless of if its playing a game.

No surprise it sucks, it's even older than GTA5 and was already weak when released...

The CPU is just slow, these core 2 duos are not fast anymore, see if you can get a core 2 quad for cheap that works with your system and see if that solves your issue. a Q9650 would go a long way towards making this usable,but i would consider purchasing a used Ivy bridge quad core i5 or i7 desktop on ebay like one of the full size optiplex machines as they will smoke even the best core 2 quads.

Unless you got a board thats ddr3 or a 4 slot ddr2 board (capable of min 333fsb for bsel q6600) lga 775 is pretty dead not like it hasnt been dead for awhile now unless you get this stuff for free

 

doesnt even make sense for ultrabudget with cheap h55/p55 + i5 750/760 or x3440/50 going for similar prices, having better ipc, ht for the xeons/i7, and straight up being able to clock higher cause you arent hitting ram limits though some trash boards may not be able to do >200fsb, msi is the best for optimized uncore at 3800 for 214 iirc but their h55 boards self destruct ALOT which i can tell you from experience (any half decent board doesnt up and die after getting powercut while in the bios or trying to recover from bad oc settings, pretty sure trash like this is what gives noobs misconceptions about oc)

I have Xeon X5450. I have ordered ASUS P5Q DELUXE Mobo. I'm thinking about overclocking it to 4GHz+ as i heard P45 boards pretty good at FSB.

Ffs if you wanna have any chance at pushing fsb buy an ep45t ud3r/p, 500+ fsb on quads for 4.5ghz+, these are the ultimate fsb clockers for both duals and quads

 

I am personally looking for good ddr2 clockers like the p5q deluxe, premium, and e but thats because i wanna see how far i can push my 1gb team 1066c6 sticks, but if you wanna have a usable system that isnt restricted to 4gb of ram cause most of the 2gb ddr2 sticks suck ass at clocking then a ddr3 p45 board is the way to go

 

Expect to be walled at 1800-2000 ddr3 atleast thats what most p45 do for ddr3 clocks, if you wanna dive into clocking ddr3 on 775 then look for stuff that scales like mad on voltage and doesnt die on voltage, when i had an x48t dq6 (now sold cause its trash at fsb) i looked at the ram voltage and holy crap it goes all the way to 3v, apparently micron d9gtr/n are pretty good for 775 but theyre 1gbit density, something more usable would be samsung 2gbit d die as those scale to 2-2.4v atleast looking at the ddr3 ic thread, for 2gb sticks its M378B5773DH0, for 4gb sticks its M378B5273DH0

 

 

Im assuming you are sticking with 775 as a hobby thing? fun platform to mess around with for ocing but i havent found any ram clocker boards better than my p5q and i need 2 more sticks of this xtreem dark 1066c6 so thats my current roadblock

I have generic Kingston sticks 2gb*4 800MHz CL6 6-6-6-18 timings. I don't know how well these are gonna handle 450+ FSB OCing. Maybe i would get better OCZ 1066MHz kits for better OCing.

I havent played around with the higher rated 2gb kits

 

Could you send a photo of the text on the black ics? Might be able to identify oc characteristics by looking it up or referencing hwbot

Cant exactly see the text but looks to be rebranded anyways so wouldnt get any info out of it

 

you gotta test how far the board can clock fsb on an e8000 dualcore, xtreem dark 1066c6 are very very good at clocking since mine can do 1520 on air in a goofy 1x3 config and these should be pretty damn cheap nowadays considering theyre like 1/2$ a piece atleast looking at my local used market. 1430 is just setting 7-9-9-10 2.2v and done, only needs performance level 9/10 depending on fsb though you should just leave that on auto if it works, oc charger enabled, clock twister set to strongest, the other 2 settings that claim when disabled may improve ram oc just leave em at auto as i saw no diff in clocking capabilities

 

My board likes the nb delay at 400 and cpu delay at 200, though for really high fsb ive found that 1000 nb and 800 cpu can very slightly improve clocking ability but stick with 400 and 200

 

Rn its 2am so i should go to sleep but later ill make a modded p5q deluxe bios with the maximus ii formula ebb as ive found that to be the best ebb, though my board is too crappy to boot >570 and only maxes out at 490 stable (all the other p5q (pros) that ive come across are even shittier than mine) with the stock p5qd turbo bios (shares ebb with p5q premium) and maximus ii ebb swap. Dont worry ive verified even commando ebbs work on p5q so you wont brick your board, infact thats impossible because its a socketed bios and you can simply reflash it with a cheap ch341a, heck with a 2mb chip i managed to get a p5q premium bios working on my p5q but that didnt do anything for ram clocking (only made it worse) but i didnt test fsb capability so may wanna revisit that bios

 

 

Once youve found max fsb then you can find your rams max speed, i advise loosening trcd and trp to 9 (may wanna loosen it more if the rams dont just no post like the xtreem darks) alongside loosening tras as much as possible, thatll give you more headroom for finding max freq, you may also need to raise vnb abit cause its quad rank and getting 1520 needed 1.58v instead of 1.56v for 1470 even in 1x3 config. If the rams dont immedeatly crap out with loosening the subs to the max then do that aswell, if they do crap out then just stick to loosening trfc to max

 

Have fun suffering =p

Thanks for all the info. I'm fairly new to overclocking, i'll let you know about my overclocking when the board arrives. Seller also sending E8400 maybe i would try tweaking it too.
