Thank you !! but I wonder is this work for my Asrock X99 WS with E5-2698V4?
- I had modified most bios for in need that if the CPU can not work stable with -70mv.Both BIOS with -50mv Vcoreoffset ffs,just flash and work.

Just for v3 onlyThank you !! but I wonder is this work for my Asrock X99 WS with E5-2698V4?
or just for v3 only.
thanks.
Im not a proffessional it, but what diferences are betwheen these voltage differences?

Just for v3 only
Thanks for the Asus Bios with EFI driver embedded. Works fine in 2696v3@x34 all 18-core with c-state on (c3 off) and no more crashes 100% stable! Using uCoce 39.You don't have to install the v3.efi anymore, you just need to instal the BIOS only. And the microcodes as the old way,most systems can automatic install by the systems itself,you can use tools to update the new one----3A microcode.
Asrock EP2C612D16C-4L(bios v2.40) and single 2696V3 ES (SR1XK). 18 core 3.3ghz %100 stable with v3x2_50_39_vcc.efi.
Do you have to disable any C-states to make it work, or have to disable or modify anything else that may limit functionality?
I think so. Why not?Do you think you could get the same 3.3ghz if doing dual processor?
you dont answer to my previous question, about different voltage!Im not a proffessional it, but what diferences are betwheen these voltage differences?
Give more power when you have 120 with 50 or 70-50 vs. 50-50?
Or is it a processor and how much can it take?
you dont answer to my previous question, about different voltage!
Thats last bios with 50-20 work perfect and i can to work with 101.4 fsb
Can it work if we make something change to 0x648 0x649 0x64a 0x64b?Which BIOS are you using? There's a bug with some Haswell that can cause EDP throttling even when sufficient current is set so to rule that out we need to set unlimited current.
Ahh, I assumed you were reading 61E from the CPU. Try the MSR walker under the function tab of this utility http://crystalmark.info/software/CrystalCPUID/index-e.html If you set it to walk from 0x615 to 0x620 do you see 0x61E? If you are trying to write to this MSR and it does not exist a fault will occur in which if not handled may cause a BSOD / freeze.
The total number of Xeon's I have had including this one is one. It would be nice to test on some others, including 306f1 and 306f0 but doesn't look like it is going to happen.
Not MCHBAR for Xeon, 64-bit power limit is also in Bus 0xFF, Dev 1E, Func 0, reg 0xE8
If the Xeon does not support ratio overclocking then setting it will probably be ignored. One can check with HWiNFO under CPU properties. I have only seen this on mobile Haswell and it was mobile CPU's that have been unlocked, not desktop or Xeon that I am aware of. Obviously not many people interested in unlocking mobile CPU's
Can it work if we make something change to 0x648 0x649 0x64a 0x64b?I will prepare some custom bioses in the Next days. Let me know which board exactly and which efi.
Can it work if we make something change to 0x648 0x649 0x64a 0x64b?
Update: Running the computer without the efi driver, c6 causes problems. With efi driver everythings fine.
@MOF so many different variables for throttling one just has to do what one can. The biggest problem I personally see is with AVX2, this seems to operate via a VID table, that is it seems to try and keep core VID below a certain value and what ratio one gets is tied to that.
Here's an example running just one thread with affinity set, just a simply loop, no AVX2. Turbo in yellow.
CPU runs at it's max 30x ratio
Now see what happens when we run just one AVX2 opcode once every 50 milliseconds on one thread of each core.
Power control gets ready for AVX2 by slamming down the ratio to 25x and from what I am led to believe leaves it there for 1 millisecond after the last AVX2 instruction before returning to the top ratio, 30x in this case. The irony in this case is that it doesn't even run the AVX2 as 256bit but needs a warm up period. Some info on Agner Fog's blog, for instance http://www.agner.org/optimize/blog/read.php?i=387. Limit reasons shows EDP logged, with the event being logged in yellow.
Now if we run the same opcode once every millisecond
Ratio is now dropping to 25x and we can see EDP continually active (red) and only using 37W of power, no current or power throttling..
Is that CC6 or PC6 (core or package state C6)?
I ask because performance is about the same with those different voltajeI'm not sure but these values must be minus(-) vcore and uncore voltage offsets.
- Thanks to dufus and C_payne share their sourse code,if they don't share the sourse code,we will not have E5V3 tubor boost,thanks again!
