How hot is your ati 4870?

[ivwshane]

I recently put together a new system that includes an ati 4870. The only thing I do on it that is 3D is SFIV and after a few rounds the system completely hangs (vista 64).

The card seems pretty hot even when just idling at the windows desktop. I don't have a way to check actual temps but it seems pretty hot to me (you can touch the card but it would be uncomfortable if you left your hand on it).

Since my system has been built from the ground up it could be a ton of things that's causing it to crash but since it's only happening when I play SFIV, I figure the video card would be a good place to start.

Just crank the fan a bit-

Use Rivatuner to check fan speeds and temperatures while you're gaming.

And as mentioned above, up the fan speed to see if that makes a difference. You really have to check the temperatures...that's the only way to know if that's the problem.

Take the side of your case off, blow big fan at it.

With stock cooling mine was running at 78-80C idle and around 90C at load and it was running flawlessly. Crysis, Stalker to name two. Do you have the latest Catalysts? And get back to us with the temp readings. Also, are you running anything OCed? CPU? RAM?

Up the fan speed

80C at idle, 23% fan speed

When I had my reference 4870 1GB, idle gpu temps were 83c and load temps were 99c (the memory and VDDC temps went as high as 119c) but it ran at those temps hours on end without issues. So you might want to stress test your system (especially if it is overclocked) using linpack, OCCT, furmark, HCI memtest, etc to make sure everything else is stable.

Also make sure your psu is adequate for you uses. Otherwise you might want to increase the fan speed like others have suggested as long as you can mind the noise or look into aftermarket cooling or something if you can't stand the noise (I couldn't stand anything higher than 31% on my reference 4870 1GB so I just simply replaced it).

my 4870 can get damn hot

at 20% fan speed & stock clocks, I've seen it at 100C idle

I normally have it at 40% fan speed, and it's 55C idle & low 70C load

I sometimes get BSODs related to atikvmag.dll when playing different games, but I honestly don't think it's related to heat and more either due to drivers or poor CPU/mobo OC settings (too lazy to determine what it is).

Wow, so I played SFIV in window mode and it would only get to about 69c and the fan speed was at ~25%.

I decided to remove one of my sticks of ram since I had issues getting it to run in triple channel mode, so far no crash

I guess I have to figure out what the deal with that is.

Thanks guys, one thing down four more to go!

Get this , make yourself a couple of fan profiles and you can forget that it's there.

25% fan speed and I'm getting 50-52C. You have your heatsink blocked by dust or your room temp is over 100 F. I can't see any other way for you to have that temperature.

had that temperature since day it was bought. Case has no dust and has large side fan running at 1200rpm.

upping the fan to 26% will make temperature go below 70C. However, when fan is at auto, equilibrium will be 23% and 80C.

My 83c idle was at 26% fan speed so I don't see why it's unreasonable. While gaming, my gpu temp was 99c was with 40-42% fan speed. So nothing out of the ordinary.

My 4870 idles at 70 C (the default I guess, since I never changed it) at around 27% and 23% fan speed. It gets quite annoying when it switches between those two fan speeds randomly as it goes over/under the 70 C mark.

You need extra cooling, add another fan towards the Graphics card.

 

[netxzero64]

you better pump up the fan speeds or it'll be bye bye... joke...

what is your PC casing? do you have good ventilation on your system?

The contact between GPU and heatsink was crap, probably. I had two 4870 and they never went above 65 C idle, with the stock cooler and the stock fan profile.

Here's my stock reference 4870 OC 810/975 after 2 runs of RE5.
The clock settings are all done automatically with ATi Tray Tools.

41c idle - 8% fan / 62 load - 40% fan

It seems that early HD 4870 512MB cards used to idle much higher and pull slighly more power than the later HD 4870 1GB, seems that yields over time improve both things. My card idles at 58C and never goes beyond 80C on full load, uses a custom black cooler with silver pipes that looks similar to the Toxic version, it can reach up to 92C but only when OCCT is used (Or Furmark), and that's all in a room temperature of over 80F. A friend of mine got a Sapphire HD 4870 1GB with the reference cooler and it idles at 49C but can reach up to 90C on full load, and can't overclock a single MHz or it will crash, I run mine at 780MHz.
