BIOS 2802 Comments

[JohnAb]

Just noticed that this new BIOS has just been released. I'll probably try it over the next few days and provide some comments here...

Always good to know what others think.

Wow. Incredible. I haven't achieved that.
Could you tell me what RAM memory you have and if you bought a Kit of 4 or 2 of 2 modules.

Using 2 kits of 2 modules. It is a bit of a gamble as the 2 kits may not be compatible. So I guess I was lucky. 😄

Wow awesome. You are very lucky. I also bought 2 kits, but in my case it didn't work.

Do you have an Amazon link/Model number of this kit? Looking to try a shot at 128GB as well on a 2702 update. I'm currently on 2602.

I am using this model.

4x32GB @ 5600MHz C40 is guaranteed on Z790 (e.g. Z790 Hero, Strix Z790A) by 13th Gen. The bottleneck is Z690 motherboard instead of CPU if you're using 13th Gen.

Hi guys. I don't know if it's just me, but after several days of use, the 2802 BIOS has degraded the performance of the 13900K.

My average score in Cinebench with bios 2703 was 38000 pts, but since I updated to 2802 I haven't been able to reach more than 31000 pts.

I've seen power consumption capped at 160w-170w, regardless of whether Multicore Enhancement is set to Remove all limits, or even if AI Overclock is enabled, while with bios 2703, up to 320w was reached if necessary without limits.

In Intel Extreme Tuning Utility, I have seen that Current/EDP Limit Throttling is on all the time with stock config (indicating that the processor is requesting power, but the motherboard is not providing it).

Becoming a bit conspiratorial... Could it be that they have done this in order to make a more substantial difference between the 13th generation and the new 14th generation, nerfing the 13900K processor?

I have gone back to bios 2703 and the power is back.

Same here. I am using intel XTU instead of BIOS settings to overclock my 13900KS on strix Z690I. BIOS 2802 increased VID of my CPU and ruined the OC functions. Here are two examples, other OC functions in "AI Tweaker" may also be broken.

The function "AI Tweaker - Specific Performance Core" is no longer feasible because Win11 always went BSOD when I set ratio limit for each P cores (other settings keep default). Applying same settings in intel XTU runs smooth without any issue.

CPU core voltage cannot keep default when I only make changes to BIOS option "AI Tweaker - Performance/Efficient Core Ratio" from Auto to "by core usage" or "sync all cores" (keep other settings default). It shows a high core voltage 1.41V in XTU while my 13900KS only needs Vcore<1.32V at 5.7GHz.

To be honest, I didn't stay in the latest BIOS to try to repair the problem. Since it's my work PC, I don't have the time to look for a solution or dig deeper. I preferred to simply roll back to the previous version and continue like that.

I am seeing the same issue with 14900K. I cannot get above 205W with a proart b660, with max r23 score of 35K. Problem for me I can't even try another bios...
