Hi there, could you share how to modify the EFIs (and compiling), or make the following versions?
v3x2_20-50-50_39_vcc1.8.efi
v3x2_30-50-50_39_vcc1.8.efi
v3x2_40-50-50_39_vcc1.8.efi
v3x2_20-30-50_39_vcc1.8.efi
v3x2_30-30-50_39_vcc1.8.efi
v3x2_40-30-50_39_vcc1.8.efi
My pair of 2696 are pieces...
I am using a pair of E5-2696 v3. BIOS is modded and microcode stripped. 0x3A microcode exists in Linux OS and I can use other versions easily. I will test again later.
I got 2.7 normal full turbo and 2.5 avx2... what am I missing out there? Is it because of 0x3A microcode? I will test it again with recommended microcode later.
Thanks btw.
Hi, I am afraid I need a PowerCut driver with no voltage reduction since my silicon is a piece of poop.
By the way, what's the difference between v3x4_50_50_1pt650pc.efi and v3x4_50_50_1pt950pc.efi? Which one is more stable? Thanks.
No. Supermicro boards do not have the option to ignore TDP limit. Using turbo hack makes the CPU reach the TDP limit, and motherboard will slow down CPU for that.
Randir's EFI is very special. It breaks TDP reading, that's why I can use his EFIs to achieve best performance.
@kjboughton did a...
I understand what you are trying to convey. However it's true that the new EFI's performance is not optimal in supermicro boards.
I am using X10DAL-I and a pair of 2696 v3. Since any kind of undervolting is unstable to my cpus,
with v3x2_vcc.efi and 0x3A microcode, I can get 3.1&3.0 with...
Same here, with my supermicro board, the EFI providing the best performance are Randir's vcc .efi drivers. No other efi can beat that.
If there are more vcc drivers that would be very great. Thanks.
Hi, I got instabilities with my dual 2696 v3 system. With vcc and mc39 efi, the temps are below 70C.
It's very likely to got kernel panic/oops during geekbench 4 test regradless of temp.
For blender rendering, if ambient temp ~22C then no reboots. If ~30C then reboot per one hour. I guess...
Same question here. Supermicro X10DAL-i.
Using v3x2_50_39_vcc.efi gives out 31x/32x in non AVX load, 27x/28 in AVX load.
v3x2_50_vcc.efi gives out 32x/33x regardless of avx or not.
(CPU1 always slower by 1x)
No microcode. Arch Linux with linux-ck. GNOME DE.
I seem to got severe system slowdown after blender rendering for 5 hours and mprime small fft for 20 minutes (Both of the work cause the CPUs overheat a lot). The system runs fine before those extreme work.
Running blender/mprime again gives fine...
I got kernel panic / oops for the undervolted efi. I am trying the efi mentioned in the quote.
I just registered to say this: if you are using this efi, try to avoid avx2 applications like mprime. This got my 2683 to 89C in few minutes. I am using Hyper 212x.
