48xx series cards MUST READ

For all of those 48xx series users whining about GPU temps. Here is the fix "until 8.7 drivers", I only increased my fan to 43%. It lowered my GPU temps from 80 degrees Celsius to 50 degrees Celcuis.

Funny - I was whining about my nVidia 8800GTS KO Edition - almost the same thing - at *idle* the damn thing runs 65-68 lol....

I found out the fan runs at 37% until it gets called to - at like 85 or so. So I used a version of RivaTuner (made for eVGA) to create profiles for my fan speeds.

Now, at idle I get 48, and when I was playing Crysis last night I was barely breaking 60 with 4XAA and 1600 x 1200 res.

ATI drivers do the same thing, the cards FAN will idle at 23% until the cards heats up, the fan will then rev up. But the current ATI drivers "ver 8.6" do not official support 48xx series cards. Ver 8.7 will support them.


Riva Tuner 2.09 does not support the 48xx series yet.

Ahhh, so the new drivers help run the fans better?

I still have yet to edit the BIOS on my 8800 to have it always run the fan at 50% regardless - I suppose that would be the best for me to do but I am a bit wimpy - I fry the card and I have no computer until it gets replaced lol

LOL, yeah. I overclock my cards in the ATI Bios as well. "Carb" is a great utility "only works with ATI though"! I have my 4870's running at 780Mhz core and 1090Mhz Memory. they re "F-en" smoking!

I belive the Forceware drivers have a Bios overclock tool as well. Just use GPU-z to save a .bin file then reboot "using a floppy disk" to the Cards BIOS and overclock it on the sub-system. Just like you do with you CPU and the motherboard.

there are some guys online posting 25% overclocks out of the 8800 "G92" series cards.

Yeah, it is something I want to try - but thanks for the little idea of using GPU-Z to save the bin -0 never friggin occurred to me even though I *already* have it saved cause I submitted it lol

Sometimes I can't see the forest for the trees.

Here is a web site that will give you a brief overview of how to overclock your Video card.

If you have any issue let me know, the site can be a-little confusing for first time sub-system overclockers.

happy overclocking, i live for this "S*&T".

I already have that BM'd lol - I love both Tom's and XtremeTech.
