Got myself Sapphire 5850 Extreme. Used money from mining on my old 8800GTX. I wanted 5870, but all reasonably priced ones were out of stock and I was lucky to get my hands on this one because they are mostly out of stock too. Or too pricey.
OCed, overvolted. Now around 970 MHz core, 300 mem, 1,25V(thank you Sapphire for new version of Trixx). At first I was getting only around 300 Mhashes/s with guiminer so I tried phoenix. pocblm core gave me around 350 Mhashes, phatk jumped between 377 and 406. But it is kind of unstable. Once I run my IM client(qip, Infium and 2005), Chrome or Flash video in firefox speed drops to 350 Mhashes. If I try to play a video system freezes. Sometimes system froze for no apparent reason, judging from the fact that freezes stopped after I stopped runing IM client there was some connection. I doesn't seem that OC is the problem. I left my PC alone for the night and it didn't crash.
Now running guiminer with -v which increased speed but now it hangs the system too when I try to open the video.
OS - Win7x64, Driver - 11.5 with SDK 2.4, Browser - Firefox with HW acceleration turned off. The bios on the videocard is untouched.

Short observation. Vectors make my system unstable.

I have 8 ASUS 5850 cards running and not a single one is unstable until it goes past 910MHz (a couple reach 940 MHz). They aren't over-volted and run under 60*C, much of that due to a smaller form factor and otherwise good thermal design -- there's virtually no risk of any dying due to OCing.

Have you had a look at what's their default volatages ?

Sapphire's one are at 1.088,  I have a hard time pushing them beyond 840 stable (at that voltage)
1.168v

How do you OC more than one GPU with TriXX?  That's not in Xfire

@Gladiator, turn off hardware acceleration on your flash movies if you have not done that. (Right click youtube video, settings, uncheck hardware acceleration). That helped me with crashes.

Mine are in Xfire but I'm not sure whether changing the voltage actually works. GPUZ doesn't report the voltage change.

If you've found my post helpful, send me some bitcoins!

Yeah, on my Sapphire HD 5830 with NO Xfire, GPU-Z don't report the voltage change.
However, I was able to OC further with higher voltage on Trixx, so I guess I really did up it.
Next step will be flashing the BIOS with the higher voltage, as the RBE shows the voltage register is available for changes.

+100

This saved my Mh/s. I had to reset O.C values to watch youtube or my computer would crash.
and I just found the VLC hardware acceleration setting so I never have to slow my card down again Cheesy

I got my XFX 5850 at about 360 MH/s at 970/1250. I thought this was a "normal" speed.

Should this card be comparable? I dont know a lot about hardware but it uses the same gpu http://www.newegg.com/Product/Product.aspx?Item=N82E16814121375&cm_re=Radeon_HD_5850-_-14-121-375-_-Product

Yes, but each card has different OC potential.

My Sapphire HD5850 Xtremes go up to 870/290 at stock voltage of 1.088. Unfortunately the temperatures would go to 870°C too, if I let them. I wonder what cooling is needed for 900+. Ice-Water?

My cards are stacked one above another (with spacers), probably would go higher higher too with an empty slot in between.

That is not possible, you would have already melted up the whole PC

I was kidding about the 870°C and meant 900+Mhz.  Roll Eyes

75'C is too much, IMO for 24/7 load.
try keep it under 70'C or preferably under 65'C :[
PC cases with 3-4-5 120mm/140mm mounts inexpensive and start cost from $30. so put some investment there !! 30+10x4~$70 for 10-15-20 temp drop isn't that much ? :-|

Wrong.
Modern GPUs can handle minimum of 105C.
I ran 9800GX2 before, and it runs 105-110C. Been running 24/7 for over a year, and no problem at all.

"can't handle"!="work efficient/long/reliable" and thats true even for Nvidia junk.
even for gaming workload, let alone 24/7 95% GPU saturation.

Unless you have something to back that up, otherwise you are just spreading false rumors.
I own and run all my nVidia GPUs at 99-100% usage (as measured by GPU-Z). It runs folding @ home projects.
I have used 8800GS, 8800GT, 9800GT, 9800GTX, 9800GX2, 9600GSO, GTX295, GT240, GTX 260, GTX 460.
All high end cards have reached 90C and above, and no problems at all. And all running 24/7 for over a year.
Just go to folding@home forums and you will see tons of people running at such high temperatures.
How hot do you think tesla clusters reach when they are packed together in a server rack? I would tell you well over 90C if not 100C+.
