4850: How Hot is Too Hot? - Page 2

In a way yes... the 4850 pulls air in from the edge of the card and pushes out the side of the card... So I think if you change that fan around you should be good.

Good Luck... I am loving my HD4850 (VisionTek). I only wished it would fold better. (Funny how folding started on ATI but then nVidia did what ever to make their cards folding gods) But it is kicking some major a$# in games...

Running mine at 675core/1040mem for now.. still playing with the voltage levels on these gpu's a tad, before the water goes on.

Stock temps at startup = 73c
Fan adjusted with Asus software, + mild OC = 51c

How are you playing with voltage? Is it a mod like the rest?

I am looking for someone that has tried to use the profile to adjust their voltages... But have not seen it yet. In .xml profile there are settings for voltages and I wander what if anything I could do with it.

From what I understand..the flash is potentially more damaging than a plain vmod. There is no telling if the GPU would/will recover from changing the voltages via the BIOS..since they do not always act 'as planned'.

I have just been using a pencil to add GPUv for some quick benchies. Full watercooling goes in tomorrow..so I have been cautious. I really just wanted to see what the cards are capable of on stock cooling. On water, a bios flash is a must, as you will easily max out the core speed that CCC allows [700mhz].

So far, with the fans set to 100%, I can run a stable 680core/1050mem on both gpu's..[broke 17k, np w/ the X3320 @ a measly 3ghz]

you should have gotten a DuOrb.... I don't go over 45C EVER under full load at 700/1100, and thats with loops of crysis running.

Unless you bork the flash, you'll be fine. No matter what values you put in for voltage, it won't let you go above ~1.2v which all the cards should be able to handle.

I responded in your thread, but here's the thread with the "softmod". Note that only certain values seem to work through the profile.

Thanks, After this topic got so far gone I had to make a "clearer" new topic title and repost.


Guys,

Thanks for all the responses Heretic got my +rep. I did not want to Flash the Bios nor do a volt mod... Both of those could clearly cause problems if I needed to replace my board due to issues later. So I wanted (and found) a software way to max out the card.

99C is still good for the stock cooler for Furmark.

I have the duorb on mine and in Furmark, I hit 80C after 2 minutes. I stopped it after that because my ram chips were HOT.

In normal games, I never even hit 60C.... probably never hit 55C (but I don't stare at the temp gauge, so I don't really know).
