powercolor 5850 - Anyone got one?

Hey. i have just upgraded to a powercolor 5850.

Im wondering what the average overclock people are getting on these cards as the auto clock doesnt work for hell....

Also, i have a 9800GTX+ for phyx but for the love of me i cannot get it to work? i followed the tutorial on other threads but confused on why its not enabling?.

Okay anyone got this card?

im seemingly having some issues. after gaming for awhile it hits over 70*C and grey screen n reboot.....

had to reset back to factory default speeds due to this... and fan never seems to run above 23% for some very very odd reason...

shouldnt the fan speed up as the temp goes up as nvidia cards do?...
 
pcs+ and i would say its well ventilated

1 x 14'' fan on front (blowing in)
1 x 12'' fan on side (blowing in)
1 x 12'' fan on rear (blowing out)

and psu fan sucking out at top...
 
The grey screen may not be down to your overclock to be fair. It may be down to the CPU/Memory clocks (the 5xxx range seem to weed out poor overclocks), the GPU voltage may be a little low (use MSI Afterburner software to set the voltage higher), try updating to 10.3 drivers, the list goes on...

I wouldn't worry a great deal about 70°C to be honest - they can go to around 80° regularly, and it'll be perfectly fine. They can go to 100°C, but it's not a great place to be for extended periods...

CPU/RAM is factory defaults. only thing im clocking is the gfx its self. not flashed bios as i've read this card doesnt support the asus bios flash :(

I have the same card and it overclocks to around 820/1150 (fell over at 850/1150 so haven't pushed it any higher or really pushed the memory overclock)

My load temps hover around 70-72 with a custom fan profile in msi afterburner that ups the fan to higher values than the standard auto fan does however I noticed higher fan does not really equate to massively reduced temperatures - probably just a limit of the heatsink itself.

Not had any grey screen issues at all but as I understand it these are more of a driver install problem and I just reinstalled win7 again so not a concern for me.

It's certainly a shame the voltage is locked on these cards as I feel with the decent cooling you could get some nice overclocks on them with a bit more juice pumped into them.
 
Hi, I have the Powercolour 5850 PCS+ cards in crossfire and they seem to be fairly well balanced cards. Like Popov, my cards are both running nicely at 820/1150. One falls over at 850 core and the other falls over at 1200 memory.

Its true that you can't overvolt these cards, but don't let that put you off. The copper heatpipes do a great job of keeping the card cool and they are quieter than the reference design ones.

I used the ATI control panel to overclock the cards and Furmark on extreme heat settings to test for stability.

With a voltage tweak and some tweaking with the fan profile my reference 5050 can hit 1000/1150 fairly easily, craps out a little after 1050 on the core and the memory goes no further than 1200. At stock voltage I reach around 900 core before I need to up the volts a little.

Must admit, I have been very happy with mine and am glad that I got it before the prices went up and they started releasing non ref design. I imagine that if based on the ref design that the pcs+ should be easily capable of more than 850?
 
The PCS version is quieter and cooler than the reference version and the fan doesn't sound like a vacuum. It does not overclock further though! Especially as you can't flash an Asus bios onto it and it increase the voltage.

Coming from a pair of non reference cards I was expecting the reference 5850 to be louder but it was anything but, really quiet and cool to the point of now realising that a clicky disk is the loudest thing in my machine. Certainly not a vacuum cleaner by any stretch.
 
i bought a 5850 pcs+ last week and used the auto on ati overdrive which did not work as all my games were crashing.

i managed to find my own overclock for it which so far is 835/1125 stable.

it runs at about 39c idle (fan at 21%) and under load ive now seen it go about 55c (the fan speed does auto increase as the temps go up)

got a coolermaster cosmos with no extra added fans or custom cooling.

was gonna get 2 of these cards but the performance of just the one is fantastic for me so far. gaming at 1920x1080 on one monitor.

note: my cpu is an i7 920 @ 4.0ghz and the memory is stock. 6gb 1600mhz

I have a pretty similar spec and the powercolor 5850, just last week, and I used MSI afterburner, even though it is the powercolor version.. MSI afterburner still works, then use GPU tool for stability test, I got 900/1150 on stock voltages stable, and I don't know how to change the voltage without changing the GPU firmware.

The Temp goes up around 80 on a stability test, the temperature is no problem, and it also doesn't really get loud at all in my opinion

ATi Overdrive also failed for me.. and I quit the test as it was messing up, it's also got a limit of something like 825MHz

Make sure you have newest drivers too, if you still get probs, lower the ram by 10, and retry, if the same problem, up the ram back to 1150 and lower the gpu by 10, retry, if you still get an error, reset to stock, retry.. if you still get an error, it's either a windows problem, a driver problem, a faulty card or not getting enough power from PSU
 
I think the rule of thumb is simply not to bother with the auto-tune - it just doesn't seem to work (although it may do if left for hours on end - I couldn't be bothered to wait that long). Just overclock it manually with MSI Afterburner, and use Furmark to stress test it for stability.
