that is normal.
my card range from 60C to 90C.
It just depend on where the card is, and the temperature of the air flowing in that area.

can some1 help me pls
why i got so big difference in temperate GPU and shader ?x2 5850
(its gigabyte 5850)

Hmmm... I downloaded the latest Trixx, but the voltage slider is still disabled for me on my 5850... any ideas?
2. The other option is to find a BIOS someone has already modified (or use RADEON BIOS Editor) to set different voltages from the existing voltage table within your card. This can be dangerous, but is achievable as I flashed my XFX 5870 with a modified ASUS BIOS. I didn't get software voltage control, but the BIOS was reporting that it was using a higher voltage than before.
If your XFX isn't a reference card it probably uses a voltage controller that isn't compatible with the bios you flashed. If that's the case it may look like the voltage is changed, but it's actually using preset values. Is it still true that Non-reference (Sapphire 5850 Xtreme) cards don't support BIOS voltage mods?
Not necessarily, as there are 2 different types of voltage mods.
1. The first and simplest is to enable volatge adjustment with MSI Afterburner, but a lot of cards don't have the relevant voltage regulators to allow this to happen.

I didn't get software voltage control, but the BIOS was reporting that it was using a higher voltage than before. Having said this, it didn't overclock any better on the higher voltage, so now I'm looking at flashing it with a lower voltage to see if it still works, but uses less power.
Well, Sapphire 5850 Extreme is NOT reference. So I guess I just blow up your hope.

I believe so. I had this trouble myself. Trying to find a place that sells the reference model is a pain. Just ordered 2 x 5850 sapphire extremes, hoping their reference
.

Any tool to actually modify the BIOS?
I would like to OC with software, then, once I found the max clock and desired voltage setting, I would like to flash the BIOS so I don't need to worry about OC again when I switch the card to another PC.
Is there a complete guide for that?

Yay!
I got my 5850 running at [email protected]. Finally. It has been stable during the day (before it crashed at 900MHz). I might try cranking it up more tomorrow.
I like how my purchase is actually increasing in value over time

This is quite nice, my 5850 Toxic is running at 1050 core/1200 memory and 1.25V while pushing a stable 399.57 MHash/s.
Temps at 68% locked fan speed is a stable 69C.
I'm quite pleased :3

That is a nice o/c, but it's inefficient compared to a 5870. You are pumping more voltage while getting less hashrate/s than a 5870.
I get electricity included in my rent so I don't mind :3
The bad part is that my 7 year old 400W PSU couldn't keep up and smelled like it was burning.. So I had to lower the clocks to 1000/1200/1.20V and pushing 381 Mhash. I still think it's good for a 120$ card (or 180$ when I bought it)..

That is awesome. will try it soon.
New TrixXX for 5850Xtreme is ready!
You can overvoltage now!
ByE!

unxetas: thanks ... I was also thinking it might be the card has some microdamage because it was running at 79C all night one night because I thought that leaving the side of the case on would make it quieter and thus easier for me to sleep... if i leave the side of the case off it stays at a good temp.. but I would like to play around with this card and try more overclocking settings and a green coolant setup. The other thing is that it may be possible to get a high hash rate but how do you know your hash accuracy?
I'd look for some overclocking guides for your specific card, but at some point you will need to up the voltage a fraction.. Which may lead to higher temps as well.
I should have mentioned that I was getting higher temps with the fan on auto, I guess I could have turned the fan up to keep the temps low at 900MHz
I guess an extra 5% output isn't worth me worrying about it anyway, at the current rate that would be what, another BTC or two a month?

I used aticonfig --odsc=960,1200 on my 5770 and was going great for a little while was even getting a 190Mhash rate but after about 10 mins of web browing the machine froze up. The temp was only about 64degrees. Is there anything else you can do to make it more stable?
I get low 60's at 900MHz now (63C stable)
My sapphire HD5850 seemed to run happily at 900MHz (340Mhash/s) but I knocked it down to 850MHz to keep the temperatures a bit lower.. It was getting up to around 77C at 900MHz, I'd rather keep in in the 60's Seems like with some decent cooling these cards would run at crazy speeds, eh?

Ordered 2 of these last night. Hope I get similar results.
