when I'm not gaming or well not running hardware intensive games to keep temps down can I disable HT on my i7 920 and disable 2 cores so I'm only running 2 cores without HT.... also can I disable my 295GTX select multiple-GPU configuration in nvidia control panel so that im only running one card in the 295gtx...

would this be safe to do to the processor and GPU?
would it cause any problems??? if so what??

would I be safe at running this setup for a long period of time if I'm not gaming (well not playing hardware intensive games)??

thank you
 
Well if your not running any hardware intensive programs surely your temps will be low anyway, will be running close to idle. Its a whole lot of effort changing all that anytime you want to do a bit of gaming or whatever.

Wether it would work or not I dont know, just saying it seems a bit.... pointless. Could just buy a low spec PC for a 1 or 200 quid and use that for internet, downloads, office work and keep that as a gaming PC?
 
as long as you've enabled speed step, when you're not running anything intensive, the cpu should downclock and produce less heat.

even disabling one graphics card won't have much of an effect, they'll be so close together that they'll heat the other one up even if it isn't in use.

on my setup, one gpu is around 8-10c hotter because they are so close together, even on idle.


you're best bet is to make a profile with a very low clock and load that up on start up, ot just get a cheap netbook or something.

what temps are you getting that is making you want to do something like this?
 
I think I see what the OP is getting at. I dont know about the 295gtx, you'll have to ask the graphics forum on that one. I would guess at no, you're stuck with it idling.

However you can certainly turn off hyperthreading and two of the cores. Mine is presently running as a dual core. Temperatures will be the same as normal if you do not undervolt it as well. If you do, mines at 0.8V and just breaks 45 under stress testing with the intel stock cooler. Set two profiles in the bios, one for browsing and films, the other for more difficult work. Electricity bill will thank you for it too, might even forgive you for buying the 295gtx
 
It will work, yeah. But surely decreasing heat/power usage at idle conditions is what SpeedStep is made for?
 
Yep speedstep in combination with vista/win7 automatically drops/raises multiplier and voltage on a core by core basis as long as you have the appropriate setting in Power Management (balanced or power save)

also with i7 if only 1 core is in use it will hold the volts & multi in that whilst reducing the other 3 (smart little chip aint it) but you will need to have turbo boost enabled
 
Do you have any data on speedstep actually reducing power draw Mattus? I had a look a while ago and couldn't find anything very conclusive. This was with P45, it looks like it may be better on X58.

New for X58 so you wont have seen on P45. Just download CPU-Z if you don't already have it and watch the CPU tab; will see Core voltage, Speed, Multiplier, Bus Speed and QPI link all fluctuate
