Windows 7: Windows 7 Freeze and Possible Time Server Problems

Furmark is the one we generally recommend. Here is the tutorial. Be sure to monitor your GPX temps. Video Card - Stress Test with Furmark

well furmark has shown some interesting things. it caused my pc to shut down within 5 mins of running on two occasions so i opened up the case and ran it again. again shuts down then the gpu reaches 120C.

not unexpected i guess, 120C sounds quite hot. my hd4850 has passive cooling so temps like this aren't unexpected.

however, lid off and a fan extracting hot air from the local area it is leveling out at 107C. so apart from that my gpu is too hot what does this mean? its cleanly shutting down rather than freezing so is this the same thing? i doubt just rendering HD tv gets the gpu anywhere near 100% and even if it does i've seen freezes when video isn't playing.

Anything greater than 100C is too hot for a video card. You need to have better air flow or better cooling. -WS

Since that is over the boiling point of water, I would say it is a little too warm. The shutdown is to protect your hardware. This indicted that your GPU may be faulty. Do you have another one you can try? Can you borrow one? I think the freezes may be related to the sutdowns in that there is a GPU problem.

i agree that this is too hot but i don't think there's anything faulty with the gpu. as i said its passively cooled, specifically designed for a HTPC and not a gaming rig. its not designed to operate at anything near 100% without much more cooling. but according to ATI it operates perfectly up to 120-130C

but as i said the gpu barely touches 25% playing near full screen hd video. temps around 80C. its not this. totally different reaction by the pc confirms this

What ATI is talking about is extreme conditions for a small amount of time. A GPU is never supposed to run hotter than 100C. I have been working with all kinds of computer systems for over 40 years. Anytime you have electronics over 100C you will get errors, shutdowns, reboots, lockups, pausing, et cetera. I did a quick survey of several machines in the office that are running high-end graphic calculations and the GPU never gets hotter than 65C running at 100% CPU. -WS

but this isn't relevant. i know the gpu is not designed to be run at 100% which is what caused these temperatures. right now I'm watching HD video and its using 12% of the GPU and running at 79C. The GPU in my HTPC never, ever runs at anything approaching what the stress test put it through.

a quick survey of forum posts about this card (and make sure its the gigabyte one with passive cooling) will show that these tempeartures are entirely normal.

Humm a bit confused here. I thought you were stating that your GPU was overheating, but now it is irrelevant? Humm.

I still think your GPU is running too hot, but that is just MHO.

Note: I entered 85C I meant 65C, typo.

no it isn't relevant. the two situations are completely different. Furmark is a test intended to stress overclocked gaming pc's . If i were intending to use my pc as a gaming pc furmark would be relevant to my situation.

this is a HTPC. the card is designed for a HTPC to deliver video at minimum GPU levels, but with zero sound. there is no fan, it is bound to be hotter than the average card, but this is the trade off for zero sound.

all furmark showed is that my graphics card is not designed to be run at 100% activity. ever. but i knew this.

did you read any of the review i linked to, here is a salient piece
Quote:
With the Gigabyte GV-R485MC-1GH, the card continued to run without any airflow in an ambient temperature of 26 to 27C at over 100 degrees. The maximum temperature we recorded on the fins was a finger-melting 98.7C and, according to RivaTuner, the core hit 106C during our stress test. We then left the card to settle down and we recorded an idle core temperature about an hour later of 62C, while the fins were a respectable 57C.

Despite these rather extreme temperatures, the card kept running and didn't crash - we were pretty impressed with this result considering it was designed to essentially cook the card until it fell over. Gigabyte's Multi-Core cooling solution certainly seems to be up to the task even in environments lacking airflow completely.
as a final test i ran prime 95 for 1.5 hours while playing back HDTV on full screen to simulate the encoding process and the gpu temp has only reached 86C. this is a standard temp for this card. it is not overheating under normal circumstances
