What controls Turbo Core in Xeons?

Cool! In a few days I will install it and tell you the result. Thank you!

Hello to all. I wanna join the "Unlock" Party too. Can someone help me? I have a E5-2698 V3 on a Supermicro X10Dai. At the moment i only use one CPU. I edited actual Bios, add NVMe Boot etc. but i cant get unloc allcore turbo. In Windows 10 my clock still is falling from 3.6 GHz (1 thread) to 2.7 Ghz with all cores.

Would be nice if someone can provide me a patched Bios.

I installed the modified bios. Is it normal that it takes a long time to boot and that I can only access the bios menu?

It may happen only first time after flashing BIOS. It takes long time to boot or POST ?

It takes a long time to complete the POST, sometimes not even that and I have to restart the motherboard. When you try to load Windows it shuts down.

After an incredable support from @topmysteries5 (MANY THANKS), my PC reached the results bellow..

The CPU is cold enough, no crashes - stabile work at 3060MHz - constantly.

In Cinebench 20 - 2856MHz for all cores (2500MHz before that)
In Cinebench 15 - 3060MHz for all cores (2500MHz before that)

 

[TECH_ATTACK]

So someone can help me too?

Interesting.. I'm curious to try with my cpu in my virtualized homelab..

@DBSDBS how did you flashed? it was the bios of post #2,632 or a new modified version from @topmysteries5 ?

I have successfully turbo boosted 2x Xeon E5 2686v3 on Asus Z10PED16-WS.
When only 10 cores are enabled on both CPUs, it runs x35 (3.67GHz) on all 20 Cores 40 Threads with non-AVX2 load. With AVX2 it drops to x32 (3.36GHz).
With all 36 cores and 72 threads, CPU runs at x35 (3.67GHz) on all cores with low-mid workload, heavy workload drops it to x30 (3.15GHz). With AVX2 x27 (2.83GHz).

Stock non-AVX2 load speed --> 2.3GHz for 36 cores
Stock AVX2 load speed --> 2.1 to 2.2GHz for 36 cores.

Cinebench R15 @ Stock -> 3844CB




Cinebench R15 @ Boosted -> 5225CB



Cinebench R20 @ Stock -> 8640CB



Cinebench R20 @ Boosted -> 10574CB

Nobody uses a SuperMicro X10DAi? Or can someone please tell me what I have to edit or insert to Bios File to get the boost?

Link me its BIOS.
Your E5 2698v3 will boost, but it will be power limited due to your mobo VRM and dual 8pin connectors. This turbo mode doubles your CPU TDP, in case of 2698v3 it will be 270W for each CPU. You will have to add fans to reduce VRM temps to safer level.

Thanks a lot. Yeah, i know thermal limitations.
Here is the actual Bios (i already add NVME boot, all other is untouched)

Wow, that was truly fast. Will flash Bios tomorrow and report results. Any settings i have to do in Windows 10 (actual Version). As far as i read, Windows tries to load uCode at startup, is that correct? If yes, how can i avoid this?

Flashing of BIOS is just a first step. LMK when you successfully flash it.

 

[TECH_ATTACK]

So, i did flash Bios successfully. What are the next steps?

 

[Phaet0n]

Finally after many attempts I got it . Thank you all.

Cinebench R15 results:

Before (2.9 GHz) = 1740 Cb
After (3.3 GHz + 102.00 BCLK) = 1980 Cb

hi, could you share bios file and some guide to do? I tried to do with Asus Z10PED16-WS + dual 2698v3 last year but no luck.
Thank you very much!

Does anyone have any modded bios files for the Asus X99 Deluxe II ver. 1902? I've found an older version, so maybe I'll just start with that. Would love to get my E5-2696 V3 boosting a bit higher. The best I've been able to manage so far without any mods is 2.7-2.8ghz by under volting.

Hi, anyone with Xeon E5 v4 can do some experiments and testing ?
I have got efi for xeon v4. Maybe we can unlock turbo on xeon v4 too.
I guess this time we will have to remove broadwell-e ucode from BIOS.

Joined the forum after reading quite a bit of this thread. Really interesting stuff and tons of thanks to many of you throughout, it has been quite educational.

I have an e5-2697v3 on the way to give this a shot in an x99 deluxe board. Currently I am running a 5960x in the board at 4.7ghz as my daily driver machine. Changing some hardware around and reconsigning the board into a 'media' machine doing lots of transcoding heavy multitasking so I figured why not take the opportunity to tinker with a 14 core xeon.

Anyways just wanted to make sure I have my head wrapped around this correctly.

-Remove the microcode entirely from a bios and flash the board with the modded bios so it initializes the cpu without a microcode essentially in an entirely factory state.
-Rename the .dll in windows that contains a newer microcode that would otherwise load in flight.
-Use vmware to make the change to an older microcode so that it loads that in flight instead.
-Make my changes in bios via multi-core enhancement along with any needed power settings.

Is that generally the idea?

v4s are not alterable.
The errata in the silicon was corrected in the v4 and later versions.
Only the 1xxx's (in v3 and later versions) can have their timing changed.

I already know this, check my last post.
