i got a new computer 2 days ago with a leadtek 8800gt. it is currently at stock speeds (core:600, memory:900)
the nvidia control panel says it is at 63C.
is this card overclockable or is it to hot?
what is the maximum temprature for this card?

63 idle or load? asumming it's idle it's ok... these card handl 90s fine

Which blows my mind, cuz thats hot. Mine to idles at 60c. Overclocked to 670/1000 just fine - ran very hot to 80C BUT if you turn off automatic speed control on the fan and jack it to 50-60% ish even OC'ed at full load it never went over 60C.

I heart Crysis at 1280x1024, DX10, all settings very high (except post processing) 30~40ish FPS. Its Unreal this card is....

its idle, so what i shuld do? raise the mhz's until i get 80 idle?

I would say 80-90s full load would be what you should be ok with.

I wouldn't shoot for an 80C idle. Like you said tho run the fan how you want to, run it where it will let you run the card and don't go over 90C full load.

help! i overclocked it to 650/1900 and crysis began showing white squares all over!, i reseted the settings to 600/1800 and it still appears!
what do i do?

Clear the drivers and reinstall them.

Lowering your OC and restarting your computer is really all you need to do when it starts "artifacting".

I have an EVGA 8800gt 600/900 that runs at ~57c idle. During load of HL2EP2 or CoD4 the temp goes to ~70c. I was thinking this was hot, but i guess not. Can i OC this card to 650/975 or higher? I know people say that this card can handle 90c with no trouble, but wouldnt a card that on load doing 70c last longer than one at 90c?

Also, how would i oc? I have rivatuner with profiles set up to increase my fan speed when temps get higher. I have it set up for 40% idle, 60% > 70c < 80c, 80% > 80c. But i have yet to even get close to 80c and my highest recorded temp on rivatuner was about 73c during load. So what is a safe OC speed to start at? I dont want UBER increases of my speed, but somthing small that i know wont hurt any of my hardware.

Btw... I have e6850 @ 3.0ghz, 2gig Corsair XMS2 PC6400 5-5-5-18, WD 320gig 7200rpm 16mb HDD.

I was going to turn my timings of my ram to 5-5-5-15 but i dont know if the nVidia ntune is a good way to do that.

I dont want to OC my CPU cuz 3.0ghz dual core runs fine to me. 200-400mhz increase isnt worth it imo.

I have an evga 8800GT Superclock that comes at 650/1620/1900 and I have it overclocked to 720/1750/975 and it never goes above ~67C with ATITool artifact test. It wasn't stable before at 700 core but I used nvidia control panel to up the PCI-E frequency from 2500MHz to 2600MHz and I haven't had a problem yet. BUT I still don't really understand what upping that frequency really does so I am going to leave it there. Soon, I am going to reseat the stock HSF with either AS5 or Arctic Cooling MX-2. and then I am also getting a Zalman VF1000-LED for Xmas and that should allow a MUCH bigger OC.

btw I have an open side panel in a P180B and a PCI blower directly below the card with the card running 90% fan speed

i've had mine idle at 36C and OCed to 800mhz core/1100mhz mem on 3DMark highest was 50C plan to try 850Mhz

Be careful with that, if you clock your PCIe too high, your SATA controler will freak out and corrupt your hard drives.

BFG 8800GT with Zalman VF1000 and custom Ram Sinks OC'd and Bios Flashed to 732/1834/1050 idles @ 38c game load around 44c, the key to OCing these cards is keeping them cool.

Not just the GPU either, you have to keep the memory chips cool too, when I first pulled the stock cooler the GPU had way more thermal compound from the factory than should have ever been on it, too much thermal compound can act as an insulator instead of a conductor, also improper contact with the memory chips thermal pads and the heatsink is also a problem with the stock cooler.

If you're going to OC and use the stock cooler at least pull the cooler clean the GPU and apply a paper thin thermal compound layer on the GPU die using a quality compound like Artic Silver 5, and reassemble it.

Also the fan settings must be increased with the stock heatsink if you're going to OC, educate yourself before you OC anything or reap the bad rewards of a screwed up card.

wow turbotrav OMG that is a massive overclock on such low temps!! fan specs please!!!!!
