For X79 E5 1680 V2's are unlocked 8 core Xeons. I have two of them. Their performance is nearly identical to a X99 5960X when both are overclocked to the same speed (4.5GHz for mine). The 2697 V2's have four more cores but are also locked.
After some quick testing (only some CB runs) my 1660v3 (8core xeon variant of the 5960x) @ 4ghz CPU and cache with 2400 CL 10 is delivering nearly the same numbers like my 4,5 ghz 1680v2 2600 cl11 is doing even at something like cb15 (no avx/2).

Clock for clock (only did some runs since my cooling is not set up) i saw a uplift about 15 - 20 %.

You bought E5-2697V3 in late July. Did you ever get it? Did you undervolt and overclock it? Can you post your CB R15 and R20 scores?

Yes received it but have not tested it yet (vor modified the BIOS). Will try it out soon.

Your post on page 82 stated that you own Rampage V Extreme. I have attached my modded BIOS file for Rampage V Extreme. You have to copy to FAT32-formatted 4GB Flash drive. Insert the drive in the lowest black USB 2.0 port. Then you press the ROG Connect button for 3 seconds before it starts blinking. After the flash is completed, the light goes out. If after pressing for 3 seconds, the light blinks several times and turns solid, this means that the motherboard did not recognize the flash drive.

Did anyone read Zen 4 reviews here? I have noticed that stock 6-core Ryzen 5 7600X scored 2481 CB scores in Cinebench R15 which is higher than 2296 CB scores generated by my stock 18-core Xeon E5-2699V3. I mean, three times less cores beat 18-core beast. That's 8 years of progress. :eek: But Xeon is 3 times cheaper than Ryzen 5. :D

Stock Ryzen 5 7600X scores 6040 CB scores in Cinebench R20, which is higher than 5986 CB scores achieved by my 18-core E5-2699V3 with supposedly 24/7 stable overclock for most V3 Xeons (-0.05 undervolt on 103 BCLK).

Im running an Ali Express 1680v2, RIVE and Gskill 2400cl11.

125 strap 126x35=4422mhz @ 1.41v, LLC Ultra High, VTT 1.15v

I'm using 125 strap to get around the memory write bug.

Not quite happy with the high voltage at just 4422mhz. Trying higher frequencies always ends up in whea uncorrectable error bsod.

Haven't really tried 100 strap OC'ing because of the memory write bug.

temps stay below 75c with H110i. I've been using coretemp and when running stock clocks the power reading goes up to 180w+ while when OC'ing im not seeing it go higher than around 160w.

I had my previous 3930k running @4711mhz @1.385v high LLC. slightly higher single core perf.

what are your pll /vccsa voltage values?

Its both set at auto. vccsa is doing around 1.155v PLL is at 1.787v

Hi,
On a good bios both should be around default 1.05v

Bad bios could max at 1.25v :eek:

i also had a 3930k, used to run at 4.5 @ 1.28v vccsa 1.2 (memory required). Since i wasnt ramping bclk, i actually got better results with LESS pll than more oddly enough.
but i wanted offset mode and EIST so YMMV

Well...If I could guess I say theoretically it is possible...I mean on X79 we can turn on Above 4g decoding in bios the thing is that someone we the little knowledge could possibly moderate the bios and solve this problem in the future.......BTW Also some people claim that resizable bar working on older card without the problems even if the GPU are not supported....here bellow pic with the R9 390....

They claim that actually unsupported GPU is not the issue if your motherboard/bios allowing that resizable bar could be turned on....

just isn't possible, these x79 boards don't have a contiguous range to enable Rebar+4G Decoding, the max is 1GB.
