Vista Killed my OC'ing

Synesthesia · 04-02-2008, 05:57 AM

I downloaded Vista SP1 from their update list thinking that it would increase the performance of my computer. Unfortunately it is now preventing me from OC'ing my ram and cpu. Whenever I OC them, the system does not recognize the OC (CPUZ), my performance does not go up, and whenever I start up the computer or restart it, it tells me, "Checksum error, checking A drive....drive not found". Then I have to restart it again to make it run.

I didn't think SP1 for Vista has come out yet....was this actually what it said it was? How do I uninstall it? I tried to in the auto update center, but it only appears on the main list, not on the list where I can actually uninstall it.

Man that stinks. I installed SP1 and never experienced this. However, Vista does set my speed back to default if I leave the PC idle for a long period of time. A simple restart fixes that and I don't mind it too much since it saves a bit on power.

Wow, I just noticed this on my machine as well. That's weird. I will check into and see what I can find out. If anyone has any idea what may be causing this, please let us know. Many thanks.

That sucks!! SP1 actually helped my pc but, im not oc'ing anything. I guess its better not to oc. LOL

Okay, here's what I've got so far.... My machine runs at stock speeds until it needs more. I am guessing that SP1 has the speedstep feature on by default. This is only my measly take on this issue and I'm sure some others who have more experience could provide more information. See the pic below that shows the difference at idle and load.

If someone can tell me how to disable speedstep, I sure would appreciate the help. I tried disabling the ACPI in BIOS but then Vista wouldn't boot up. That may have been the wrong setting to mess with anyway. I would certainly appreciate some information on this issue. Thanks again.

Yes, I'm back. I think I have this figured out now. Like an idiot, I was looking for an actual "Speedstep" setting in Vista. Apparently it's all handled in the Power Management settings.

See link: http://www.vista4beginners.com/power-management?page=1

So if you set the processor Power Management to a minimum of 100% that should run your processor at your OC full time. I am at work right now and will try it when I get home to be sure.

As expected, when the minimal processor state is set to 100%, the OC stayed. Not a bad feature IMO. No use in running wide open if there is no need for it.

I agree, why run balls out when you don't need too?
