Dell XPS and 8600M GT..

post #1 of 6
Thread Starter 
I have 2 questions, really. First one, and I've looked in the bios but I couldn't find the setting for it. my CPU seems to be having the speed throttling issue, dropping to 1.2gHz then climbing up to the full 2.4 speed. I can't find a setting to resolve this? It's nothing like my evga bios

Secondly, the 8600M GT is giving me issues. I'm not sure if it's the card, or just the fact that it's a laptop and not truly meant for gaming. The people at the Dell forums, while not Dell techs, did not seem to know much (or anything near as much as you guys ) about the issue.
Anyway, Temps on video Idles at 55C. It jumps up to 60-62C just opening IE, one window, single tab (version 7). So.. I thought I would load up GPU-Z and CPU-Z. GPU-Z shows stock speeds at 475/950/702. I was using EVGA Precision, similar ( and written by the same guy) to RivaTuner.
The game my wife has been playing has been DragonShard. Not a terrific game, but she enjoys it so whatever. Well, it's been crashing when armies get built up and lots of things going on. The Precision tool, when I load this game and minimize, shows the video drops to 182/365/602.
Is it supposed to do that? I wouldn't think so.. I haven't had time to play the game to build up the units and see how the temps rise. Takes time I haven't had yet. Could this and/or be the CPU throttling causing a CTD?
Specs are below.

Well most laptops have this power saving function, though I am not familiar with that I do know that if you don't use it much you can press a button (or click something) to let it run at a low speed. And if you need it to be faster then you can press the button (/clik a button) and it'll run full speed again.

And if I am correct laptopts have very strict temperature safeties... So I'd check the temps you're running while gaming (because an instant 10C higher by opening IE sounds like a lot to me)

My XPS does the same thing. I can disable Intel SpeedstepTM in my BIOS tough.
My 7900Go don't underclock tough.

Yep. I disabled SpeedStep, but it didn't seem to have any effect. I can OC the video though. Not that I want to, particularly since I'm having this cooling issue.
I don't exactly look forward to dealing with Dell's Tech support. I've known a few that worked there and I know more than they do.. but they like to talk like they know it all. Amusing, it is.

I let it sit Idle and the temp will creep up to 64C and the fan will kick on. Doing nothing but sitting there. I guess it's a call to Dell Tech

But the video card dropping the clocks like that? 475 to 182? Is it supposed to do that? Not familiar with mobile versions.. but my 8800gts doesn't change clock speed when I get into a game. The laptop does.

your problem is powermizer
what it does is it allows the nvidia cards to have multiple settings (almost variable) depending on how much the driver "thinks" u need in order to save some battery. Although I haven't tested this aspect, I personally perfer to keep it on as during non-gaming periods, the card is underclocked while I can still OC for gaming. This way, I feel that I don't have to push my laptop so hard all the time especially when I'm not gaming. Here's my setup...using rivatuner, powermizer underclocks to the standard 2d setting while I overclock in the performance 3d tab. This I have tested...during gaming, clock/mem will shoot up to my OC (540/830), but on the desktop/surfing web/ms word/etc, it stays at the standard 2d of 169/100. If you're intent on disabling powermizer (which will allow you to keep the performance 3d setting at all times) then look here: http://forum.notebookreview.com/showthread.php?t=261929

Hope this helps
