AVX offset. Should I OC differently for flight sims?

[Ace McPlane]

Hi,

I followed the Der8auer guide on overclocking my 9700k and I have a stable overclock at 5.1ghz with an AVX offset of 4.

I'm wondering if I should OC it differently though since I play a lot of flight sims and I know that a lot of them do use AVX workloads from what I've heard.

 

Since DCS world started crashing on me, I've been thinking about redoing the overclock, but that could also just be a bad update or something.

Any thoughts on this?

I do notice my clock speed jumping back and forth between 4.7 and 5.1 so something definitely is happening with AVX in the background.

If AVX is sufficiently important it'd be worth try OC'ing without AVX offset at all and see what's the highest all cores frequency achievable there.

 

I honestly think you can get to 4.9ghz if your cooling is sufficient and that'd might offer better performance on the greater scheme of things.

 

Then again, with such a powerful CPU at such high frequency I'm sure your experience is satisfactory either ways right?

Well, it's VR right and it's flight sims so even with a high end CPU, I'm pushing it pretty hard.

 

I'm going to try everything else first to fix this crashing issue in DCS, but I guess I'll try a new OC without an offset as a last resort. With no AVX offset, temps increase like crazy so it's something I'm trying to avoid. Yea, 4.9 sounds about where it'd land.

I mean what is the rest of the hardware? saying so should always be part of the OP.

Sorry, ASRock z390 taichi, 9700k, asus strix gtx 1080 oc gaming edition, Samsung 970 evo 500gb nvme m.2, Corsair ax760, 16gb 3200mhz corsair vengeance RGB pro, Fractal Design s36, etc.

So, turns out that I have a bios bug that's causing the AVX offset to kick in where it shouldn't. I had to change the bios setting for the CPU overclock from "all cores" to "specific per core" NOT regular "per core".

I'm already updated to the newest bios and that didn't fix it so just going to do this for now and wait for the next bios update I guess.

Thanks!
