Anything past 1333 and it gets flushed. That PLL should be already a bump but back to 1.905 it goes.

See above edit... The PLL voltage is the most fiddly of all the voltages for socket 1366. It can make or break stability in an OC.

Unfortunately not me. Would be fun though!

When the next round of stimulus checks come out I'm thinking of selling my E5 2683 V4 if I can find a 2699 V4 or 2696 V4 for a somewhat reasonable price. 22 cores, 44 threads should be great for video processing. I've been watching Ebay for them.

R23

4.3ghz stable. Now to tweak down voltage.

 

[TheUnbrained]

Personally I have only experience with X79 V2 Xeons and my current 2697 V2 OC great via BCLK (115,2)+turbo also I owned 2650 V2 and that one also went up to the 113 on BCLK...now when it comes to the X99 and V4 Xeons CPU's I never tried but all stories that I heard are not so promising when it comes to the BCLK OC most likely best case scenario will be around 105.....tho' you never know...

well, i go for another way now: 6900k for my main pc and a new dualsocket 2011-3 + 2x E5 2695 v4 instead using a sluggish rack (RX300 S6) and a core-restrickted selfbuild-server

but tbh, i go for one E5 2650 v4 anyway for ... eh ... science purposes lel

I finally settled in on 4.37 GHz and it's been running like a champ for a while now. ASUS Motherboard P6T DELUXE V2---- Xeon 5670 ----16GB 2x8GB DDR3-12800U 1600MHz

 

[freeagent]

Thats pretty good! 4.3 @ 1.312?

4200 comes in at 1.325 for me I think. 4400 is 1.4v on mine, so your doing pretty good I think!

 

[Edwired]

Thought PLL don't work on westmere as @lexluthermiester you said that ages ago

 

[Toothless]

So 4.25ghz is seeming set stable. Passed R23 and CPUz stress. Gonna see if it pass the WCG/rosetta jobs I gave it

Does anyone here own a 2660/2670/2673/2678 v3 here? If yes, what chinese mobo do you recommend for it?

Got Lenovo C30 mbo with 2650L. Will upgrade soon, to make more BOINC points.

 

[Toothless]

4.25 not stable. Gonna drop it once I stop hating everything and get back to more tweaking.

Looks like the dual cpu set up isn't happy at all are you getting freezes or bsod.

I guess use lower blck and enable turbo mode to get the overclock you want. That what I been doing on my set up.

As it running turbo with 175 blck @ 4.37ghz @ 1.304v @ qpi/dram 1.275v, dram freq 1,750mhz @ 1.64v @ timings 10-10-10-28

It's BSODs. I'll check back on it and it restarts itself which tells me it ain't stable.

 

[Edwired]

If it restarting on it own without bsod usually tells me the PSU is not able to provide power quick enough or add more/less vcore and/or qpi voltage. But list the bsod each time you can find a list 1366 bsod error codes explaining what needs be done.

It's literally just windows erroring out. There's nothing about providing power quick enough or not enough power as I can run the same voltages or higher and still have this issue. At this point it's either ram or cpus that don't like this high of bclk.

 

[Edwired]

Like it windows freaking out and giving out different error codes usually point to the ram timing. Try loosing the first 4 timings and test it

I've been looking into X99 systems and the possibility of building a many-core Xeon workstation with ECC memory and Quadro graphics card.

Anyone had experience with the Chinese Huananzhi X99 boards? They're definitely affordable and capable, but there's less information in regard to their longevity.

Most likely I would go with a board and processor combo like this one: Huananzhi X99-TF & Xeon E5-2678 V3 combo

I own the E5-2678V3 paired with HuananZhi X99TF. This is a quality board with 10 layer PCB, 6 phase VRM power delivery and good chokes and caps. Has bootable NVME M.2 plus, another NVME m.2 slot, and an m.2 slot for the BT/WiFi card. There are 5 (LGA-2011-3 E5) Haswell's that support DDR3 or DDR4 and the X99TF provides choice with either 4xDDR3 slots (gray color) or 4 x DDR4 (black color), up to 64GB in either bank. It's sister motherboards are the X99T8 with 8xDDR3 slots and the X99F8 with 8xDDR4slots. I am very pleased with this motherboards quality, price and performance. Cheapest I have seen on AliExpress of late is around US$105. http://www.huananzhi.com/html/1/184/185/362.html

There are AliExpress package combos with E5-2678V3 + 32GB REEC DDR3 1600 + X99TF that run about US$260 (plus shipping/duties/taxes).

MiyConst on Youtube has an excellent review of this MB (EN or RU). Also, his Turbo unlock and TU tools are excellent and easy to use. Took me 20 minutes to TU my platform. All core 3.3Ghz with CB R15 = 1824 , CB R20 = 3912. Cooling...a 6 pipe SNOWMAN (160W TDP rated) dual 120mm for $32 keeps mine below 60C with 21C ambient under full load conditions. P95 stress pushes it to 70C.

One more thing......Did you maybe consider Xeon V3?As I know 2678 V3 is really cheap + on Xeons V3 it's possible to do all core turbo hack so.....

All Core TU worked with MiyConst tutorial (Youtuber) the first time I tried it with E5-2678V3. All core 3.3Ghz on a Chinese HuananZhi X99TF with 32GB (desktop 4 x8GB) Mushkin Redline 1866 DDR3. CB R15 = 1824 , CB R20 = 3912.

E5-4627 v4
3.20 GHz

View attachment 181952View attachment 181953

The E5-2678V3 (~US$85, 12C/24T) with TU up to all core 3.3Ghz will exceed CB R23 = 9500+...on air. Must be a lot cheaper than the E5-4627V4, no?

I'll actually be using my build as an engineering workstation and so it'll be interesting to see how reliable it is. I'm looking into a 4x8GB kit of 1866 DDR3 ECC registered memory for this one.

I guess the dual socket boards are also an option, but considering how much you can get done with 4 cores and 8GB memory, I'm expecting 12 cores and 32GB of memory will be heaps.

Been busy lately pushing the x5675 it doing well @ 4.375ghz @ 1.312v still on turbo mode with qpi/dram @1.29375 V. Had to drop the ram to 1400mhz as it was getting glitchy after 1754mhz I couldn't figure it out why it was doing it unless it was one of the timings needed changing

 

[Toothless]

Name to be decided. Probably Standoff because that's literally how the coolers are mounted. Standoffs.
2x x5570.
24GB ECC (stole some from the SR-2 due to cooler issues.)
Eventually HD5750
SuperFlower 750w

If i was to install tall ram I would use dremel tool to take off a few cm off the fins on the cpu cooler to make it fit as it don't affect cooling that much
