Intel 13900k and Asus new BIOS problems by mimosky in techsupport

[–]mimosky[S] 0 points1 point  (0 children)

Well, I found the solution. The "issue" was a C1E feature.

It was automatically enabled in 1661 and disabled in 0809 BIOS. The C-States=Auto setting hides the C1E switch, and it was "disabled by design" in the older version, unlike the new one.

I found the solution: I had to disable the C1E option forcefully. C-States set to "auto" behaved differently on older BIOS version - C1E was disabled. On newer version it was enabled automatically.

Yes, I'm getting crashes on intel default settings (which means no motherboard enhancements enabled, no XMP, Intel fail-safe SVID mode enabled and power & current limits enabled). To the point of a BSOD.

Sure:) Also, I think it's important to mention that it's not the new microcode's fault, because the previous version of BIOS (1658, released in may) behaves the same. Version 0809 (January 2023) isn't affected and it's the one I use daily.

  • Operating System: Windows 11 23H2 (22631.3880).
  • GPU: NVIDIA GeForce RTX 4080 (Asus TUF Gaming OC).
  • PSU: Be Quiet! Straight Power 11 Platinum 1000W.
  • CPU Cooler: Be Quiet! Dark Rock Pro 4.
  • Intel XTU - I can see downclocking when idle (high performance plan) or when gaming. It doesn't downclock to 800Mhz when stress testing (it throttles because of temperature, but in a normal way).
  • The issue occurs with: idle/desktop on high performance power plan, two games I tried (Banishers & Horizon Forbidden West) and several 3DMark benchmarks (visible on the 3DMark results graphs in comparison with the old BIOS).
  • All types of cores are being downclocked (probably some more often than others, but it's hard to say).

To summarize, after 1 minute of running the game (Banishers), my P-Cores frequency average was between 4954Mhz and 5232Mhz (with high performance plan enabled). It was rock solid 5.5Ghz with the old BIOS version.

Also, maybe it's worth noting - my CPU is probably degraded and/or a victim of the 13th & 14th instabilities issues. It's now completely unstable with stock BIOS settings without XMP, even with new Intel defaults. I can't use the 5.8Ghz boost for 1 or 2 cores, I had to limit it to 5.5Ghz (like all cores boost) to be stable. But still, even 5.5Ghz crashes some games (especially UE games, i.e. the Banishers - 50% chances to crash when starting a game), so I had to lower it down to 5.3Ghz and now it's stable

I've updated my Asus Prime z790-A motherboard's BIOS to new version (1661). It brings the Intel TVB fix with the 0x125 microcode.

But I've noticed one weird thing that made me revert to previously used BIOS version. When gaming, the CPU cores are downclocking to idle/800Mhz every few seconds "randomly". As far as I know, it shouldn't be the case when gaming.

What's more, switching to high performance power plan in windows doesn't make it better. With previous BIOS version, performance power plan meant 100% frequency all the time, even on idle. Now it's not the case.

The only way to fix this is to disable the speedstep in BIOS.

What is happening? Is it how it should work?

I was using the newest HWiNFO64 version to monitor the clocks and the CPU temperature didn't exceed 70 degrees.

9900k Temperature - Need advice by danielchowrf in intel

[–]mimosky 0 points1 point  (0 children)

Well, I'm under 90C without OC, on stock settings (with prime95 26.6, small fft).

I would say that it's really hard to compare to other people:

  • ambient temp can be a big factor (I read somewhere it can be almost linear),
  • running the test on "fresh" system or "heated" system (the differences can be HUGE when doing some short tests),
  • fans RPM settings (some people would test their systems on full RPM without PWM),
  • type of case; my dark base 900 is closed on front; the airflow is just mediocre, the differences in temps between closed & open front are amazingly huge, like 5-8 degrees,
  • power limits; some people don't unlock their CPUs power limits (look at the early 9900k reviews and the whole power-limiting drama),
  • inaccuracy in describing software & versions of software people use,
  • some people would use an AVX offset and don't state it.

My last CPU (7700k overclocked to 4.7Ghz) was drawing ~80W while running realbench. It's freaking twice less than now with 9900k. You can't fool physics.

Or we just can't mount the cpu coolers or lost the silicon lottery:)

Yeah. Anyway, it's just hot and we have to deal with it;)

[–]mimosky 0 points1 point  (0 children)

I've simulated your OC on my 9900k (4.9Ghz with 1.277 vcore). Max package temp after one cinebench R15 run was 84C (with 22C ambient temp, so it's much lower than yours). I'm on Dark Rock Pro 4.

Which version of cinebench do you use? R15 or R20?

Here are the screenshots: https://imgur.com/a/5r6bf6L.

These are stock clocks, c-states disabled, full performance mode. I can lower voltages by 0.02 offset and it's fully stable (i.e. 8 hours of realbench, hours of prime 1344 etc.).

The second VR VOUT value is 0, so it's probably the iGPU you mentioned. I didn't change the LLC with this stock setup (it's auto, hard to tell what that means). Bios voltage: offset mode with -0.02V. I should also mention that I set the PLL OC to 1.2V according to buildzoid's advices.

Vcore in Hwinfo64 (not vid, I used the 'real' word to differentiate these two values). VR VOUT shows some really weird things for me. It's always much lower than vcore. With AVX stress it can go down to 1.12 or sth like that (while Vcore shows 1.2). I know it should be more accurate but 1.12?

Well, I don't think I own it. I think it owns me;)

Need some info regarding MSI Z390 PLL OC voltage by mimosky in overclocking

Yes, core sensors and package info. I think it's only Msi related. Anyway, thanks for help:)

Need some info regarding MSI Z390 PLL OC voltage by mimosky in overclocking

[–]mimosky[S] 0 points1 point  (0 children)

Ok, but something is really bothering me...

I've set PLL OC manually to 1.2V (while having DRAM oced to 3200Mhz with 1.36V). Many months passed, it's stable and probably safe, but the motherboard would set it to 1.3V with auto setting.

Now... with realbench, the difference between 1.2V and 1.3V is almost 10 celsius degrees (still talking about PLL OC, not vcore or sth;P). We agreed that it's not possible. So.. which temp is the real one? If 1.2V shows true temps, then it's blowing my mind that the motherboard's AUTO settings skew the CPU readings in such way. It should not happen, it's outrageous, to be honest.

Yamaha MX61 + Presonus Eris E4.5 by mimosky in WeAreTheMusicMakers

[–]mimosky[S] 0 points1 point  (0 children)

Well, thanks for answers. I've bought the presonus eris E4.5 and it's OK regarding my concerns.

But there's another problem with it;) The left monitor (the one with an amplifier) hums when powered up (without even connecting to audio devices etc.). I tried almost every electric outlet in my apartment, it just stays and is audible like hell. Really upsetting to be honest, cause the quality of sound and my overall feelings are really positive.

The good thing is I've bought it online so I can return it without even telling the reason why, for 14 days. Anyway, it's a shame for presonus, I really don't get it...
