Hell, with 1.25V at 4.5Ghz, if your on an AIO or custom water loop, I'd throw 1.3V ~1.35V on that baby and go for 4.6Ghz or more. My 5930K requires 1.338V to remain stable at 4.5V and 1.375V to run game stable (but not prime) at 4.625Ghz (125Mhz Strap). I have been running between those clocks (depending on use case) for years now with no issues. I have half though about picking up a J Batch 5960X on ebay or something as they come about for under $250 just to get some extra life out of X99 if I can maintain 4.5Ghz or more with the chips. Have not decided if it is really worth it though as all I mainly use the PC for is 4K gaming. I'd probably get more out of a new platform all together at this point... although x99 has by far been very good to me over the years!Still rocking the 5820k. It can do 4.2 GHz @ 1.1v, 4.4 GHz @ 1.2v, 4.5 GHz @ 1.25v. It beats or matches Ryzen 2000 series in games.
You might get a kick out of this - I'm using my ancient TRUE 120 (Opteron 170 days) and it keeps it under well under 60C in games and ~70-75C in RealBench. Gotta love soldered 22nm. Thermalright sent me a 2011 bracket for free. I could probably get away with 4.6 on air without running torture tests but there are so many claims of degradation and I really don't want to upgrade right now. Holding out for desktop Tiger Lake or the AMD equivalent (used 5960X is tempting though).Hell, with 1.25V at 4.5Ghz, if your on an AIO or custom water loop, I'd throw 1.3V ~1.35V on that baby and go for 4.6Ghz or more.

Damn, that's nuts! But I suppose at 1.25V, you are still safe on air. I bet pushing past 1.3V would yield different results for temperatures. It seems like you have a damn good chip though; the IMC on my 5930K freaking blows; I can only run up to 2400Mhz on the DDR4 using the 100Mhz strap. System will not even post if I try 2667Mhz on the 100Mhz strap (no matter what I do). So, since I had to make the jump to the 125Mhz strap, I learned to embrace it and pushed my ram to it's rated speed awhile back. Occasionally I am still fighting a random issue of a complete screen freeze in a game or folding at home (when performing a GPU WU) that never happens if I run at the 100mhz strap and 2400Mhz ram speeds. Not sure if its memory timing related, my cache speed can't handle it (its still at default 3500Mhz as I stupidly don't have an OC socket with this board), or if the IMC is garbage even at the 125Mhz strap. Quite frankly, I have no clue and have been just trying a setting here or there over time to find the source of the problem. The way it simply hard freezes and does not reboot or BSOD has me thinking cache or IMC instead of CPU Core or Input voltages. Still trying to see what is up... I have my SA offset at +.102, I tried raising this with no success and 0.102 is what I use at 2400Mhz and it works perfectly. I have heard that's a voltage which has a sweet spot and nothing more to be gained with extra juice!You might get a kick out of this - I'm using my ancient TRUE 120 (Opteron 170 days) and it keeps it under well under 60C in games and ~70-75C in RealBench.

Maybe I'll try 4.6 @ 1.3v and see what happens. My other settings on the Asus x99 Strix are 100 strap, 2666 DDR4, 1.1v SA, 1.9 VCCIN, 3/10 LLC, 38x ring @ 1.1v.
I upgraded to a Xeon 1660v3 (bought for $160), overclocking to 4.2ghz @ 1.25v
Only negative is the ram won't run above 2400, but I am totally fine with that. No increase in game performance that I noticed, more so, my final upgrade to this pc before I upgrade the whole platform.
I had a 5820k, its earlier in the thread. I ran it mostly stock for its life, then the last couple of months ran at 4.2ghzDepends on the resolution you game at from my findings (and various articles out there). At 4K, barely noticeable in benchmarks more less any games (less than 1% in my testing between 2400Mhz and 2800Mhz). At 1440P, I was getting maybe 2~3% by going from 2400Mhz to 2800Mhz on the memory. Not a lot, but if you can run it, why not right to ensure no bottleneck? Can't say I've ever tested 1080P, but from what I have seen out there, maybe an 8% increase at higher RAM speeds (3200Mhz+)? Generally the GPU is the bottleneck anyway on high resolutions and if the CPU become the bottleneck, likely, RAM is not going to help you much, maybe just with some higher minimums from time to time. I believe RAM means much more for those doing more than gaming; for example video encoding, 7zip, etc. I will say, it seems "smoother" at 2800Mhz, but honestly, the data shows it may just be a placebo effect. Hard to argue hard data!
From my understanding; AMD Ryzen see rather large gains though; where as Intel does not.
Curious though; why did you go Xeon? What did u have previously?
Yeah, I could see it not mattering as much going from 6-core to 8-core for games if the IPC is essentially the same and the clock speed remains the same. I'm sure you might notice a difference in other tasks though (encoding, etc.).I had a 5820k, its earlier in the thread. I ran it mostly stock for its life, then the last couple of months ran at 4.2ghz
Also running 3440x1440
I didn't run extensive testing, comparing numbers but just from playing games, not large benefit that I noticed.
Worth a read IMO, it compares different ram speeds on the x99 5820k platform: https://techbuyersguru.com/gaming-ddr4-memory-2133-vs-26663200mhz-8gb-vs-16gb?page=1
A bit late to the party, but I was just wondering exactly the same thing and my Internet search brought me here.
I have been building and modifying PCs since the 90s. In 2014 one of my friends asked me to build him a gaming computer with a budget of £2000 (approx. $3K then). It was quite difficult at the time to choose between the i7-4790K and the i7-5820K. I built systems with both and I just felt that the i7-5820K somehow seem more responsive, so against the popular vote I decided to go X99 instead of Z97. This PC is still going strong after a couple of graphics card upgrades.
The problem was that I didn’t have this sort of money available, but I really had to get an X99 system too, so I put the pieces together buying s/h from ebay or open box. This has been my main system for the past nearly 6 years. I don’t really do anything that demanding, its just like have a car with a big V8 its nice to know the power is there if you need it. It is nice and quiet on air cooling and overclocked to 4.2/4.3GHz with auto voltage.
There have been a few little upgrades over time where I have fitted a larger M.2 SSD and added an extra 4 x 4GB ram ($50 s/h and exactly matched the other 16GB).
Along the way I have built quite a lot of PCs for other people and have built a couple of systems to compare with mine as possible upgrades. First a Ryzen 5 1600X system and later a Ryzen 5 3600 system. Neither felt a worthwhile upgrade and got sold/passed on.
I had a big birthday during the first lockdown and had to cancel plans for a celebration trip, so I thought what the heck I should build myself a birthday/lockdown PC. So I put together a system with an i7-9700K/GTX 1660 Super (not really a gamer), top rated 1TB M.2 SSD, 16GB of 3200 memory and a decent zmZ390 motherboard. 6 months on this system has been gathering dust and I am still using the X99 system. The new system runs cool with all cores at 5GHz, but again it really doesn’t make me wasn’t to use it.
So in October I thought it was worthwhile spending some time/money on my old faithful X99 system. The M 2 SSD speeds always seemed a bit disappointing so I bought a $15 PCIE NVME M.2 adapter from Amazon. This has speeded the HD benchmarks up considerably. I then went a bit mad and bought a $300 i7-6950X from an ebay seller in HK. This arrived via FedEx in 5 days without any issues (a relief). Currently this is at 4.3GHz all cores at 1.32V. Honestly I can't say it feels a whole lot faster, but it makes me smile and benchmarks pretty well. Not sure whether to keep it or try to push my i7-5820K a bit harder.
Maybe I shoud have waited for a 10 series i7 with hyperthreading added back in. Currently looking at Zen 3 with interest.
Thanks for reading if you got this far!
Yes I noticed the overclock on my i7-6950X disappeared when Windows updated to 2004. Assume it is still broken on 2009 (20H2). For now I rolled back to 1909. This is only for Broadwell/-E isn't it? Anyway will do an 20H2 install on a spare SSD and check out renaming the mcupdate fileAlso disable spectre/meltdown for added performance
what voltage are you running the cpu at?
X99 board prices are crazy. Not sure about the Chinese X99 boards. If they were more sensible I would put my 5820K into a system for my daughter.I'm planning to switch to a 5900x when available.
Could spend 300 on a replacement board of the same type but with its age and how much I use it for things I think its time to upgrade.

In the UK you can pick up a 5820K for
£50/$67 with a one year warranty or an 5960X for £135/$178 with a 2 year warranty. Both these prices seem very good to me.
6950X is still expensive here, £370 from the same retailer if they have stock. By taking the risk of buying from China for £199/$260 I could probably sell mine for a small profit if I decided to sell it now.
10 cores/20 threads was just too tempting

Well i built a 9700K system as a replacement and even after clocking it to 5.0 it has been sitting around unused as it didn't feel any faster.Still feels quicker than my sons 8700K rig, X99 versus 1151 platform I guess.
I had one of those Chinese mobos, it worked pretty well honestly.
Thanks. Good to know there are some other optionsAnother cheap option is to find a z440 board
1.9V? No way dude, that CPU would blow out of the socket... lol. I'd believe it for the input voltage though... Hell, I run my 5960x at 1.3Vcore to run 4.625Ghz. I can push 4.8Ghz with 1.4Vcore, but that gets very hot...5820K for life, bro! It is my son's PC, now. Rocking 4.4 GHz / 1.9v. I love the X99 platform. I was so sad to see how the X299 platform turned out...ended up going consumer with Z390 late last year.
My 5960X could not clock as high as my 5820K which was interesting. My 5960X box is now an ESXi machine.
EDIT: corrected some nostalgic details and added more context.

Haha my bad man - it is input voltage. I haven't been in my ASRock Xtreme4's BIOS in FOREVER. Thanks to this thread I'm tweaking my OC a bit to accomodate XMP on my RAM at 2800MHz (not shabby for 32GB!).
Looking good after 1 hour each of Intel XTU CPU and mem stress testing:

I just got a J batch one for 130 bucks but I haven't tested it out yet.Honestly, I moved up from a 5930k to future proof a bit more and lucked out in the Silicon department, both with OC and IMC.
If you check ebay every so often, you can find an amazing J-Batch 5960x for sub $200. Which is a nice upgrade with 8C/16T in mind if you want to gain some extra life out of the rig.
FWIW:
10,012 - 5820K @ 4.54GHz (1.30v); 32GB DDR4 @ 2800MHz; stock 2080 FE
13,628 - 9900KS @ 5GHz (stock); 64GB DDR4 @ 3200MHz; stock 2080 Ti FE (outgoing GPU - replaced by 3090 FE)
18,084 - 9900KS @ 5GHz (stock); 64GB DDR @ 3200MHz; stock 3090 FE
84.5% higher CPU score...9900KS versus 5820K.
As a retired professional scientist I love measubators who collect data, if I drop a hign end videocard in these systems this prob. gives me a 10FPS +/- diff in frame rates?
