Issue AVX Offset - Coffe Lake - Gaming
Issue AVX Offset - Coffe Lake - Gaming
Hello.
I purchased a Coffe Lake 8600k with Asrock Fatality k7 z370.
There seems to be an issue with the AVX Offset.
When I set an AVX offset, the game frequencies keep fluctuating between the set and actual AVX rates.
I know games don’t rely on AVX instructions, but what’s happening?
Yes, I now grasp your situation more clearly, thank you. Although Prime95 v26.6 Small FFT (without AVX) is suitable for thermal testing, I recommend avoiding later P95 versions which include AVX. For stability testing, I suggest using alternatives like Asus RealBench, which offers a realistic AVX workload to assess overall system stability (CPU, RAM, GPU). Details can be found at http://rog.asus.com/rog-pro/realbench-v2-leaderboard/. AVX should not be enabled merely for gaming purposes. My testing of various Z170/6700K and Z270/7700K motherboard/CPU setups—including my own rigs—showed that adjusting AVX Offset to "0", "Disable", or "Auto" consistently improved performance.
The issue you're facing stems from a BIOS problem. Until the z370 platform is ready and BIOS updates with proper fixes are released for flashing, avoid using AVX apps. If you must, disable AVX offsets. But if you choose to use AVX apps, create separate BIOS profiles for gaming or app execution.

Your issue stems from a BIOS problem. Until the z370 platform reaches maturity and BIOS updates with proper fixes are released for flashing, if you're not using AVX apps, I recommend turning off AVX offsets. But if you do use AVX apps, you can configure different BIOS profiles for gaming or running those applications.

Thank you for your reply.
I see now that BIOS patches should resolve the matter. No?
But I’m still confused about something.
You told me to disable AVX offsets, but I don’t quite grasp it.
My goal is to achieve a high overclock, but with AVX offsets, if not, the stability drops and stress testing at that frequency causes significant heat.
As I understood, in games you didn’t use the offset, so the ideal is stable OC without AVX.
Of course, as long as no AVX frequency is enabled in the games.
Do you understand?
Apologies for my English.
Thank you
Apps and stress tests that rely on AVX code will notably raise Core temperatures since higher Core voltages are needed for stability.
Avoid enabling AVX if not required.
If the AVX offset doesn’t work correctly, it complicates overclocking. Using AVX applications leads to increased Core temperatures and reduced stability. That’s why AVX offset was added in BIOS for the 6th Generation.
4th Generation faces significant challenges with AVX due to the absence of an offset in BIOS. The only solution is to manually lower the clock speed by roughly 200 to 400MHz to preserve stability and prevent Core temperatures from spiking excessively.
Once again,
if you avoid AVX, then do not enable it.

Apps and stress tests which use AVX code will significantly increase Core temperatures because higher Core voltages are required to maintain stability.
If you don't use AVX, then don't enable AVX
. If AVX offset doesn't function properly, it makes overclocking more difficult. Using AVX apps increases Core temperatures and decreases stability. This is why AVX offset was implemented in BIOS with 6th Generation.
4th Generation has a serious problem with AVX because there is no offset in BIOS. The only alternative is to manually downclock by about 200 to 400MHz to maintain stability and keep Core temperatures from going through the roof.
Once again,
if you don't use AVX, then don't enable AVX
.
Ajamm.... Now I understand.
So... what I didn't know is that you can completely disable AVX, how?
Anyway, I hope they can solve the problem and the AVX offset is adjusted correctly at the right time. What do you think? Previous generations also happen? If so... less likely to be solved.
Oh, thank you. So, where does AVX disable?
I saw your comment on ASRock's Forum. Check your motherboard manual. Open BIOS and search for "AVX Offset" – it’s usually in "OC Tweaker" or "Advanced," then "CPU Configuration."
However, that setting only adjusts the AVX offset, not completely disabling it.
Changed the value to zero (0), indicating no offset, which turns off AVX.
CompuTronix:
Simply assign the value to zero (0), which means no offset, thereby disabling AVX.

I can't set 0.
Only from Auto or from 0 to 31 :-(
