So I recently upgraded from an FX 8350 to an Intel Xeon 2680V4 X99 CPU, however after installing all of the chipset and various motherboard drivers it seems the CPU will just not hit 100% load.
In several programs such as Blender 3d and benchmarking tools the CPU will max out at 86% load and drop to base clock while doing so. The same thing even happens in prime95
This doesn't happen in safe mode or on linux so it is definitely something to do with drivers, however I've reinstalled any of the relevant motherboard drivers a few times and I've still not had any luck gettting it to go past 86%, all power options in windows are set to max performance.
Anyone have an ideas what driver could be causing this?
Did you completely reinstall Windows after changing hardware, or did you just add applicable drivers to an existing installation? I ask because Windows is notorious for throwing a fit when there's new hardware present.
Aside from that, are there any power saving features enabled in your BIOS?
No, this is running from a previous install, all I did was clear up any drivers that may interfere and then install new ones when I got the motherboard and CPU installed.
I have tried messing with the C state and some other power saving stuff to no avail, the fact that it works in safe mode is somewhat of a sign that it is OS based anyway right?
Interestingly Intel extreme tuning strees test is totally able to clock the CPU to its turbo and run at 100% happily
Really some weirdness going on here. I'm still almost certain its an OS issue as its only happening on this install, however reinstalling it with the current development setup I have going on would be a nightmare so I'm going to have to go through and remove drivers or something before I can get it to work correctly it seems like.
If you have a spare HDD or SSD laying arround, then i would suggest to just do a re-install of the OS on a diffrent drive or partition. Just to check and be sure.
Basicly it should be possible to make system backup from your applications, documents and settings. And put them back on a new clean install.
I probably might run into similar issues, wenn i´m going to upgrade to X99. I´m kinda suprised that you were even able to get it work. But i guess you are using Windows10.
This is indeed really odd. Never heard of similar issues before either. Especially not with Windows10. However, i can only think of some issue with your Windows10 install indeed. But yeah upgrading from AMD to Intel is allways a bit of a hassle.
Re-installing is allways the best option, or maybe a sysprep?
Yeah a sysprep might be a good way to get it backed up and for an easy reinstall. Will try it out tomorrow though and see how that goes I guess, can't really see any other options. I guess I'll just take note of all my programs and make sure I keep all of the main installtion folders at least and it should be a relatively simple process with any luck.
Might be an ES chip. In that case you can flash as often as you want, it wouldn't change anything. Also I don't see how this would help since it works perfectly fine in another OS with the same bios.
So not great news, after a fresh install of windows 10 I loaded up and ran prime95 and right away my CPU dropped to 1.89ghz and stopped at 86%, really have no idea what could be wrong with it at this point honestly
Again runs totally fine in safe mode hitting 100% no problem...
Seems like something within windows that doesnt run safe mode is the issue
