If you don't need the clockspeed from the 1660s, 2699v3 is a massive core boost so they'd be more useful for any sorta VM stuff or multithreaded tasks. 

Well yes of course. I also have two 2690v3s that's handle Proxmox as well. 

[the pudding]

Yoooo this 5960X is damn solid, the thing managed 4.8GHz all core rock solid and can get 4.9GHz just about bench stable with some uncomfortable voltages, just finished an overnight run of P95, which turned more into a 12 hour run since it seems I needed a lot more sleep than I've been getting lately lmao 

[the pudding]

Has anyone here got experience with the asrock X299M extreme4? I'm eying up one of those or a an X299X aorus master but there is an issue with that which makes me a bit iffy on that whole thing 

[the pudding]

Hmmmm, I'm running into an odd issue, I wound up going for the X299M extreme4 with a temporary 7800X, running 4.9GHz 1.4v with 2v VCCIN, 1.15v cache and +350 on the uncore offset, I've got fans pointed at the vrm heatsink and it's barely warm to the touch so likely not that being the issue (especially since it doesn't trip up in stress tests), but when I do anything involving memory or cache my cpu clock speeds plummet to below stock 3.6GHz clocks, has anyone run into this before? I've not delidded the proc as things stand as the core temps have never seen above 70c, but I guess it could be possible that it could be some hotspot somewhere that doesn't have a temp sensor that can be seen in software perhaps? if anyone has any suggestions on this front gimme a shout

AVX offset? It's very aggressive on X299 AFAIK. 

 

Also, isn't 1.4v rather spicy for these chips, or do they actually handle it okay? 

[Kilrah]

I just undid all overclocking on my 5960X for probably the first time ever, back to stock, MCE disabled, speedstep enabled... so hot here right now, 100W drop in idle power draw is welcome

I don't believe I have any AVX offset on, but considering it's not doing this in anything that touches the cache/memory in any meaningful way it'll do this, OBS, old games etc

 

Yeah 1.4v is fine for skylake X as long as you can cool it, but even under prime 95 (which doesn't seem to trigger this behaviour) it never touches more than 65c so I'm good on that front

Hmmm... tried turning speedstep/C states off? Turbo needs to remain on, but disabling any other clock/power state management stuff is usually worth a shot.

Yeah I always turn speedstep off when I overclock, I like seeing the big numbers at all times  

 

I'll give the C-states a go though, not sure if that'd do it or not, it didn't do this on my previous X299 OCF with my old 7920X and I left C-states alone on that board, but worth a shot 

[the pudding]

So it turns out the c-states in bios were off entirely so I'm going to move to the next step and delid the cpu, see if it's not an internal hotspot tripping some kind of protection, knowing what intels Tim job is like, wouldn't surprise me at all 

[the pudding]

So delid didn't sort it, must be some bios setting I've missed or something

I just realized I could legally post in here now!

Sorry to dig up an old post here, I thought I remembered someone here had at some point used a micro 2 with a 7980XE, just wanted to ask if you'd run into any issues at all running that combo? my current board it seems is no good, running into some clock throttling issues when I hit the cache/ram hard which it seems is a somewhat common problem with asrock boards so need to replace and it turns out I can get a brand new micro 2 on amazon imported from the states for a pretty good price, just wanted to know if you ran into any issues/concerns with that combo since this is also along the lines of what I'll be aiming to run too 

[the pudding]

New proc in today, I wanted a 16 or 18 core ideally, buuuuuuut a 14 at 5GHz daily, I can't complain at all

Only about the power bill

Should be okay on that front, not running into any issues on that front

Yeah, unless you run stuff constantly, power draw doesn't really seem to matter. I've only seen an impact to my power bill when running a stack of GPUs 24/7 for one of the F@H month events a year or two ago.

 

And interestingly, games reaaaaally don't seem to pull much power. Running Star Citizen and my usual browser/music/discord combo, pulling around 330W from the wall with my 6950X and 2060 Super. I'm pretty sure if I put the 6950X under Prime95 load it'll pull that much all by itself.

The heat output can be wild though.

 

My 5820K and 1070 will heat my room by about 30 degrees Fahrenheit in just an hour or so, depending on what game I'm running. Really nice in the winter, completely abysmal in the summer.

Yeah it's not seeing load 100% of the time, really just when I'm working and then lesser so when I'm gaming

Yeah she does get a bit spicy, my home office is currently 28C with the window open lul, but I'm not toooooooo fussed about that all told, I can live with that

For tax and in an "if I have to suffer then so do you" kind of way, here's what the machine looks like lmao

Yo just an everyday normal guy here with a poweredge r910 and four intel xeon e7-4870's thats LGA 1567!

Good news! My quest to aquire X58 - X79 - X99 - X299 is complete (all EVGA boards too)! 

 

Bad news! A story in 2 parts, brought to you by UPS:

 

 

And the functional damage:

 

POSTs, recognizes all RAM slots, everything seems fine. Going to slap my CLC 280 on the CPU, throw in a GTX 780, and see how it runs for actual use. Have put in a claim with UPS so we'll see what comes of that. If they fail me further, I'll see if EVGA can be any help, but this board is out of warranty so no idea if they can actually help or not.

My next upgrade will likely be X299 with an EVGA board.

 

The more Intel doesn't release an HEDT platform, the less I want a modern Intel chip.

Damn. Hate seeing that damage and hope the best getting to the bottom of it. 

 

 

Hey guys! It's been awhile since I've actually dealt with any Intel Xeon stuff but I got a few questions for you guys. So, I purchased a Mac Pro 4,1 that I got for $300 that's a dual CPU tray with older Xeons..quad core chips I don't remember exactly. Anyway, since the Mac Pro 4,1 uses delidded dies, I purchased a set of 2 Intel Xeon X5680 3.33GHz SLBV5 processors. This, being my first time delidding, decided to use a 3" vice...now I know this is probably what went wrong. I used the shear method to delid from the die and during the process of one of them, it looked like a section of the substrate was bulging off center below where the SMDs are on the gold pad side. Eventually the solder gave and delidded. 

 

Now, when I put both of them in after cleaning up the CPU dies by using high grit sandpaper on a glass tabletop with even pressure, one of the X5680 CPUs do not recognize 2 memory channels on the motherboard as they lite up stating there's a problem with two. Go into memory tab on About this Mac and they show the slot is filled with the correct DIMMs. I've tried swapping CPU sockets and the problem follows. I even installed the original CPUs and they all work correctly. Here's the funny thing about this particular chip though. 

 

So a cold boot will turn the memory lights on as previously stated, but when I were to run a Geekbench or Cinebench synthetic test, the processors get warmed up. I go to reboot the system and voila!, they all show up now accordingly. I was looking at buying another X5680 to delid and install but was wanting opinions/recommendations on what they would do. 

 

Also, if you were to buy another X5680, do you have to buy them in pairs?? On eBay, some sellers sell them as pairs and I don't know if they're all the same and you can just buy another one, or it has to be specific in needing a pair.

Why not 2x Xeon Gold 6254 (18c/36t @ 3.9GHz turbo all cores, 6-channel DDR4-2933) with Gigabyte C621-WD12 motherboard ?

Yeah. I would love a modern Intel system, but the fact that I don't get quad channel RAM, or anything past GPU + 1x NVMe has to go through chipset, is pretty bleh. I do hope they do an X499 or something at some point (as AMD stole the 399 already).

Huh, mebbe something is off so slightly that heat expansion or something puts it back in contact. Only thing I can think of, something about the conditions changing makes either a socket pad or something inside the CPU make proper contact so it can talk to that RAM again.

Not that I know of, selling them in pairs seems to be for convenience (a 4-set is also common as that's another socket config with these chips).

Cost, and likely no ability to OC. Those Xeons have an MSRP around $4400 new, and are only 3 years old (released Q2 2019) so they're plenty current enough to be in a bunch of server racks still. Usually Xeons don't get cheap until they're old enough that datacenters start upgrading, flooding the used market with them. Tis why 1366 Xeons are so cheap, I imagine 2011 Xeons are much cheaper than they used to be as well (I haven't checked), and 2011-3 Xeons are becoming more and more affordable.

 

Yeah, most on eBay are $2600-4000+ each. QS listed for $999. A 7980XE is only around $400 at first glance, can probably score a deal somewhere. I got this 7980XE (delidded with aftermarket flat nickel plated copper IHS), an EK Magnitude block, and the X299 Dark for $600 off a friend. UPS rained a bit on my parade with the board-bending thing, but even if I'm not able to get a replacement on their dime, still a solid deal with a mostly working motherboard.

 

Which to continue that, yeah it seems to be working fine. Currently running Windows 11, only have a GTX 780 in here (my 2060 Super is on a waterblock and I'm running air/AIO until the UPS thing is sorted as I may need to pull the board) so potato graphics but:

 

Running FO76 on potato settings fine. Some Prime95 as well, on this EVGA CLC 280 it seems to keep around 3.4GHz allcore boost under AVX-512 smallFFT, hottest core got to 61C, coldest to 50C. Original owner said he had 18C differences before the new IHS, so 10-11C between cores is solid with just a stock AIO plate. I imagine the block is flatter so will be interesting to see if the difference between cores narrows once I can put it on water. To that end, I have my 360GTS rad and trust EK D5 waiting, also got a new thicc 280 rad to go in the front of my 750D, as the GPU will be in the loop too and the single 360 was close to the limit with that and just a 6950X (Out of the X99/X299 chips, Broadwell-E is the most docile):

 

All my rads up to this point have been 30mm so the 60mm seems incredibly chonk .

 

And I'm all out of order but too tired to really care, observe what is truly my finest work:

 

I had to take the Phi out as even with Above 4G Decoding enabled, this board still hates it and refuses to POST with it in (other than that it's currently running same as in the pic). My X99 and X58 boards don't have this option (Classified/Micro 2 and Classified respectively), need to see if my X79 Dark does and if it will play nice, I think I saw some more workstation-leaning settings in there last I poked around. Otherwise I resign myself to the fact that picking XOC-focused hardware is probably not the best choice for weird workstation hardware.
