6800GT @420/1200...?

PNY Geforce 6800GT currently running 420/1200mhz...? I have been playing with this card for a few hours and the temps have only gone to about 64C tops and idles at 52-53C...


Do you think this is safe...? No artifacts or any other problems and this is with stock cooling also...

One other question what does upping the AGP voltage in the bios really do or affect...?


thanks for any info...
 
What the hell kind of cooling do you have, that the card (especially at those speeds) only tops out at 64C? :Q

Mine (also PNY) is running 400/1100, and idles at 60C..load well over 75...

mine idles at 50C, and my max speed is 405/1100 🙁
load is about 78C
 
Just stock cooling...? I ran 3dmark03 several times to make sure...?

I`m to assume then the temps are good... 🙂 I just kept pushing and pushing 5-10mhz at a time and finaly got the GPU to lock at like 450mhz but will run at 435mhz...?
 
Ah, there you go. 3DMark03 does not stress the card. If you want an accurate picture of your temps you can either do the 3DM01se nature torture loop or you can run 05 over and over again disabling the menus and repeating of course.
 
RTHDRIBL puts my card at 68C max. eVga6800gt @ 440/1196 and Thugs GS bios mod. TX Thugsrock 🙂 NV5 is the cooler I use.
 
Running Far Cry and having riveratuner record my temps in the back ground got about 5C highier than rthdribl could.

hmmm..... not the case for me. Any 3D or GL game gets mine to 62C max
 
I use one of the HL2 levels with lots of water or Doom 3 to heat up my video card. After putting AS5 on instead of the white silicone crap that comes on it, I see a max of about 67 C after playing HL2 for about 20 minutes at 400/1.06
 
Well I ran RTHDRIBL for 2 hours and it finaly got up to 74-75C (bounced between) and seemed to be stable there... Still no artifacts or problems... I may opt to put a better HS/fan on it or...? I have another card I am going to test tonight and possibly sell or trade this one...?

WTF? Please explain how 3DMark03 does not "stress the card", but 3DMark01/05 do? They might use shaders, etc. in different ways (which means that sometimes you'll see artifacts in one but not the others), but they all put an essentially 100% load on the fixed-function rendering of the GPU. Any differences in heat output between different benchmark programs are going to be fairly small.

This is like saying that Prime95 does not "stress your CPU", but Folding@Home does. They may use different parts of the CPU, or put more or less load on the memory subsystem, but the amount of overall heat generated by either is pretty damn close to the max that the CPU can put out. The only way to get closer to the theoretical maximum, realistically, is to have inside knowledge of the design of the CPU/GPU, and to write a program that executes worst-case code in terms of heat output. This usually involves looping over a handful of instructions that don't do anything useful when run like that, and so will never happen in real life.

It raises the voltage being supplied to the electronics on your card through the AGP slot. Increasing this is usually a really, really bad idea, as it can damage your card and is unlikely to help increase an overclock. This is NOT the same as modding a card to increase the GPU/RAM voltage (which is also dangerous, but at least might help with stability at higher-than-stock speeds).
 
man, 1200 ram speeds is impressive. I have never pushed my GT past 1100, though the detect optimal says I can go to 1140... I may have to try that, 420/1100 was getting old anyway... 😉

Scale it down on the ram...like 1150. Otherwise you're looking good🙂

Volts=big negative w/o water.
 
My EVGA 6800gt runs at 440 / 1200 with stock cooling. have had it there from day one.
If you are not getting artifacts it should be ok 🙂
 
Wow, just ran that RTHDRIBL and my GT hit 86C! Kicked all the case fans up and made very little difference. Would love to change out the thermal paste on the stock fan but I've got a BFG and would hate to ruin the lifetime warrenty thing.

Wow....86C......that's freakin hot!!!!

And I was worried that my cpu was hitting 60C.

Unfortunatly 86c is not that hot for the 6800 cards. Thats why nVidia says the threshhold is 120c, though that is pushing it in my book. I don't think you have much to worry about at 86c

BTW are you overclocking your card? If you are then the warranty is null and void anyway so might as well replace the thermal grease.

Yea, I guess your right.

lol, I ran my BFG 6800GT at stock speeds for, get this, 10 min after install! After that I oc'd using coolbits to 400/1100, now I am at 420/1100 and may go up to 430/1140 soon just for the fun of it. At my current speeds with the NV 5 cooler I run 52-54 c idle and 62-64c load, down from 54 idle, 72 load before.
