Hey sup

Nvidia ForceWare 56.64 make's all my game's look good but make's my FX5900 Ultra run too HOT!!

ForceWare 53.03
GPU core temperature: 44C / MAX Load: 55C
Ambient temperature: 33C

ForceWare 56.64
GPU core temperature: 54C / MAX Load: 69C
Ambient temperature: 43C

And this is with my normal o/c of 500MHz/950MHz.
Why does 56.64 it get 10C to 15C hotter then 53.03?

Please Help? and a fix plz :rant:

Common with all FX cards, The Issue resolves around a flicker fix which increased core temps.

FX cards have a very high heat tolerance. Long as you're not getting up to the 90s, your card will be perfectly fine.

I have the same problem with the drivers!

saturnotaku : you say that they go up to about 90c eh? Just by chance if it does go above 90c What will the affects be and will it have a permanent effect on the card.

ChrisRay : I'm assuming that the flicker fix cannot be disabled. Also how comes it's happening in this version and not the 53.03 set.

Its not common to all FX cards. Doesn't happen with my 5900nu flashed to a 5950u and running 300/500/100!!

if your FX card is running in the 90'sC then you should be verry worried and switch off and investigate probably your either very high room temperature or maybe just your very high case temperature. ??

you can normally accept max temp's in the high 60s to low70's area?? The card may accept more than this, but more than likely the Nvidia driver/core protective throttling function will shut your 3D core speed back to 2D levels or even lower. operates differently depending on whether you are using a 5900, 5900u or 5950u!!

Use Rivatuners temp monitoring facility and deliberately let the GPU core start to rise to 80+ temps and watch the speeds being clocked back

Just watch it when your card starts to artifact down the road. That's exactly what happened to my 5900NU that was BIOS flashed. It ran great for a few weeks at 485/485 but after that, artifacts galore. Strange thing was, temps were being reported as lower than when my card was a 5900NU.

Things that make you go hmmmm....:eek2:

Thats why I flashed back down to 400/850


I usually max @ 80C now in really hot weather, So The core temps wasnt worth getting any higher.

Hmmm 80oC is still a little on the high side for me. Question is there a way to make it cooler without adding a water cooling solution! and will the next set of drivers put the temps up even more?

Come on!

the FX 5900 series is meant to work at very high temps.

if you look at the Temperature Threshold in the drivers, it's set at 140 °C!
Which means the card begins only to worry at that temp and clocks itself down. So the point of no return is probably around 150-160 °C.

My FX 5900 Ultra (Asus 9950) is often running above 100 °C under heavy load. The PC hasn't crashed once since I bought it (8 months ago)

EDIT: for what it's worth, it's also possible that the new drivers fix a problem with the probe temp algorithm, and that now the new drivers return the correct temperature (this kind of things often happen with BIOS releases of motherboards).

Damn i now know that the newer drivers have some effect on Fx users who flashed their cards. Nvidia must of cought on to these tatics and put some switch or bug in their drivers to make hell for Flashed FX 5900's to 5950u. I suspected this when i was getting artifacts or flashing in UT2k3 on menu screen. I use 53's no probs here.but 56's all hell with temps and event viewer errors.

jjeeezzz GPSnoopy! 100! :afraid: See now I'm one for pushing the max outta things but only if I had an unlimited budget! and I understand that they could of updated the code for the temp probe.....but it's taken this long! Well let's see how the new drivers do!

I'm not even overclocking, it's all default clock. :p

AFAIK Asus cooler isn't as efficient as the default one, but much much quieter.

Ahh I see! Sound isnt an issue for me I've go 9 fans going! I just use in-ear earphones.....no worries what so ever! :)

So how come the NVIDIA control panel on my PC shows "Core slowdown threshold" set at 140C?

I really don't think 90C is a problem for these chips. They're not CPUs, you shouldn't judge what's acceptable by the standards of what's OK for a CPU (and people are *wwaayyy* too anal about CPU temps too IMO, but that's another issue).

100C :retard:

Mine Radeon is running 72C under full load but still :retard:

ATI and NVIDIA should think about cooling solutions, I mean it's :screwy:
