You tell us. You just unlocked a Step 1 ES v3 Xeon...
No, unfortunately deleting µCU doesn't work. Injecting v3_1.ffs into the latest MSI X99A SLI BIOS was enough to get all-core 2.1GHz instead of 1.89GHz on E5-2630L ES stepping 1 (with no additional BIOS settings needed, they all were set to their defaults).

When I also deleted µCU and then flashed this BIOS, the system wouldn't start at all. My 'guinea pig' friend will have to buy a stepping 2 CPU. Or there are other options? No second BIOS on this mobo...

I told you whats happen to my pc.
i think -50 its too much, i have blue screen
Just like on my CPU Vcore offset -90mV and Vcache offset -70mV is too much.. Leads to blue screens. However, I'm just talking about BIOS settings, no efi drivers and no additional BIOS modification (efi driver injection) apart from deleted µCU.

System freeze when I attempt to access power profile under Control Panel -> Power Options when using Payne drivers
Can anyone confirm this

Determine your motherboard brand and model,different brands of motherboards have not the same DXE insert,like ASROCK FFS should insert into the DxeCore,and you should use UBU torecalibration. ALWAYS after using MMTool/UEFITool, simply open ROM in UBU and choose 0 (Exit) to finalize file. Or you can tell me your motherboard brand and model,I can help to make kind of MOD BIOS.

I said here what does not go to E5 2696 v3 with Asrock OC formula to improve, if he wants, the one who made these efi, for us, help us ... and we help him see how I go Some motherboards or processors. Just that was my goal to say
Thanks to C-Payne for helping us!

i do it like you sayd 3 pages ago
In dxcore i inserted
i converted to ffs the beste efi form me v3x2_50_vcc.efi but i ve get erorr on boot
maybe i do something wrong, i will try tommorow

I can't confirm this, but after I ran CPU-Z stress-test for like two minutes, my system froze. Not during the test, but soon afterwards. I loaded v3x2_payne_70_50.efi the 'traditional' way. I did not inject v3x2_payne_70_50.ffs into the BIOS file. I'm gonna revert to manual BIOS settings.

Guys is it possible to have mines run 3.6 on all cores?, How do I start?.

3.6GHz sounds unlikely, but you can try. At least 3.4GHz sounds realistic to me, given that you have 4 less cores than a E5-2696 v3

MSI X99A GAMING PRO CARBON.7z

I recommend trying the alternative method proposed by CANONKONG first. Just flash the modified BIOS and then read the readme text file and set BIOS settings manually.
I would be happy if you reported back to us.

Awesome so just download and flash right

Kalistoval,

1. flash the BIOS "\Modded BIOS (MSI X99A GAMING PRO CARBON)\E7A20IMS.130";
2. read "\Alternative method, no EFI driver use\readme.txt", follow the advice;
3. Use screenshots in that folder as a reference which BIOS settings to change;
4. Read parts 6 & 7 of "\Instruction (universal)\Unlock Turbo.htm"

I fallowed all the steps and after about an hour of tinkering turbo wont go past x26. Id does show now a max turbo of x37 and my uncore can go up to x36 however upping this in the bios doesn't produce any results.

You need to go through the steps 6 and 7 from Unlock Turbo.htm that I've inculded. I can see on your screenshot that you haven't.

Also, what software did you use to load all the cores ?

Please check private conversations on this forum and delete my skype name from your message.

I have uploaded some more undervolting core/cache voltage driver combos, also including the .ffs already:

https://peine-braun.net/public_files/XEON_V3_BIOS_MODS/EFI-Drivers/

Enjoy.
@C_Payne: After running for more than a day, it appears to me that the 14-core 2683v3 is very much stable at 30X with Vcore of 0.86V. Got me thinking hard again to try something lower since I pretty much run my rig 24/7. Would you be able to add more Vcore-cache voltage options when you have time in the same folder that you have created? I'm looking for v3_payne_90_90 (checking the effect of lowering cache voltage) and possibly all the way down to v3_payne150_150 and something in between. 20mV increment should be fine, at least for 2683v3 but not sure about the 2696v3 that most people have here in the forum. When I switch my bios to factory version (Asrock x99m killer has two bios chips), the Vcore voltage is running at 0.78V at 25X CPU core ratio. I know that by increasing the CPU core ratio, you need to increase the Vcore voltage but I don't have any data points between 0.78V to 0.86V. Maybe I overshoot the Vcore voltage? Thank you in advance for your great help.

@kjboughton

Can you explain your setup? How is your temperature? With mod, the cpu idle temperature goes up by 5c to 10c which stay around 42c to 46c. Even the temperature is fine, I am not comfortable for long run.

For the record. My system: supermicro x10dax dual 2696v3 qgn7 and 102.5 bkl. I have tried v3x2_payne_70_50.efi and sadly system became unstable. Reverting for v3x2_50_vcc.efi and uCode 27 which is stable (x34 and x33 multipliers).
