Overclocking, Hyperthreading & Virtualisation

[shameelx1249]

Alright, thanks for all the info. At 1.35v and 5.3 on p cores and 4.1 on e cores id be surprised if I could boot in to windows but il give it a try.

Any quick way to do a msfs stress test. Seems painful to constantly change settings and keep loading msfs again and again

In your 12900K BIOS, do you have hyperthreading enabled or disabled, and what about Virtualization Technology? is it enabled or disabled?

[Goranged]

Also HAGS? Game Mode? Resizable BAR?

[Suburbannun]

I think Hyper enables, virtualization disabled.
Hags on, game mode off, Resizable BAR on.

[LinenOrc9251924]

wow, that’s surprising (keeping Hyper enabled).
so in review: we’ve got, Hyperthreading enabled, Virt. disabled (BIOS), then in Windows 10, I’ve got Hardware acceleration ON, Game Mode Off, and Resizable BAR on (XBOX resizable bar I’m assuming)?

[LinenOrc9251924]

It’s got to be a bad chip, where did you purchase that 12900K? Was it in the gold disc, unopened?

@Suburbannun

Mine is clocked with Curve at 1995 and 950v. Memory at +800, Power Limit at 110, Temperature Limit at max. Custom fan curve at 100% when it hits 60, my personal preference. Now it won’t pass 79 degrees even flying in NYC, real crazy weather, everything Ultra. LOD 200 which is CPU bound and that’s the sweet spot for my CPU and 30 to 45 fps in VR.

love the tips but something is wrong with your PC thermals if 100% fan at 60C can only keep it to 79C… (i think)

hahaha, you are right, there’s a typo there.
Instead of 60, it should read 80.
The thing is that with this card, I rarely hit the low 70’s.
Cheers!

I’m no expert by any means but something looked wrong there!

[Scarmax68]

I guess it’s a case of YMMV with Hyperthreading since I don’t see any noticeable difference in VR performance with HT on or off. (i7-10700K, RTX 3080) Was worth a try anyway.

[Salem978]

It once seemed to make a large difference, I think we’re down to slight if any on older CPU’s like my 9900k

I think, or at least my guess is for any difference for newer CPU would be with DX12, Re-BAR and above 4G also engaged … at least that’s a theory I look forward to testing someday.

[DensestSnail693]

Having upgraded from a 3800X I can confirm that on my rig SMT disabled no longer has any benefit (DX12). This is (loosely) backed up with almost identical Cinebench single core scores.
5800X, rtx3060 (with resizable bar on)

[JGL574VRG2]

I have a 12900k and in many times I have tried HT off, I didn´t “feel” a gain, if you´ve got temps problems, disabling HT you´ll see a gain for less throttling, maybe that is the case of someone.

[ContrivedTea675]

same if set power limit to 100w
