Problems with GA-X79S-UP5 board - please help!

Heh ... "reviews", right /



No updates, but they are most certainly aware of the problem. As far as I know, there is a long internal email trail to figure out the issue.

Normally, this kind of throttling would either be triggered by the VRM or CPU internal OCP but both having VRM under LN2 (temp) and disabling cores doesn't resolve the problem. But as I mentioned in my previous post: with higher voltage and changing to 1.25x BCLK, I don't get the throttling at 4.3G, even though the power consumption should be higher. So, I reckon it's something else ... but I don't know what. I'm really interested in the answer, though .

It's not in "some cases" and not "only over 4.4G".



Well, just tested that BIOS and it doesn't so you shouldn't tell them it's fixed . F4r, F4s and F4t all exhibit the same issue.

//edit: well, seems like a solution is in-bound ... well, an interesting solution that is. More info today, I think.

Now you got me excited Can't wait to see what was devised and especially what is the cause Looking forward to that update!

By the way, in my tests I did manage to stop the throttling by disabling cores, or rather by specifying in Prime95 Small FFT test or LinX to use less cores. However, the higher the voltage or the overclock, or both, the less cores and threads you have to use to avoid seeing throttling. So maybe at 4.4GHz I'm able to stop throttling by using only 3C/6T in Prime95 Small FFT but then at 4.6GHz I have to drop that to 2C/4T only. With that said, there could still be throttling occurring but it could be very quick so that I do not necessarily see the transitions any more. Just thought I'd share that observation. I'm pretty sure that at some point in time I documented it in one of the other threads...

I also did not observe throttling when AVX is not used, but that's not to say that it would not happen with a high enough overclock/voltage combination even without AVX. Not using AVX just reduces the overall current/power demands so it makes sense why throttling stops (at least to an extent).
