Try disabling Cool-and-Quiet, or try installing a tool called "RMClock" and force the processor to remain in a single p-state.

I have a feeling it may have something to do with demand based clock throttling.

Subject: [H] Hi All / System stutter problems


Hey guys,
Nice to see the list is still running - I've been away for a *long* time :( I applied for voluntary separation plan at my work yesterday though, so maybe I'll get back into this a little (going back to running my business full time instead of 2 careers)...

Anyway, I'm having an odd problem that I'm hoping someone may have some experience with. I upgraded my Win XP PC w/o reinstalling the OS (went from nForce 2 Ultra to nForce 4 Ultra board) - I don't really have a choice. Everything works fine, except for this nagging issue. Games play fine and frame rate is high, but I get stutters in games (pause for a split second then jerk forward). Oddly enough, the same thing happens when playing DVDs in PowerDVD and videos in Windows Media Player! :( Another odd issue is that my desktop icons get refreshed occasionally and are slow to redraw... I have the latest mobo drivers, video card drivers, DirectX (reports no problems), etc. Here's my config:
DFI LanParty UT NF4 Ultra-D
Athlon 64 Venice 3500+
EVGA 7800 GT
2 GB Geil PC3200 2-3-2-5
was using onboard sound - about to try my old Audigy
2 older IDE drives, 1 SATA, 2 IDE optical drives

BTW, I did use DriverCleaner Pro to clean the cabs, clean for NVIDIA motherboard / video, and clean Creative... I've tried different versions of the video drivers as well. TTYL,
