Topic: HD5850 @ 340Mhash/s - page 6. (Read 43288 times)
Have you tried submerging your miner in mineral oil?
I'm running 3 HD5850 Saphire cards in my miner (open air cooled, mounted on a piece of plywood).
I spaced the the tops of the cards apart with 2-liter pop bottle caps (the connectors have a little flex to them). This keeps the cards much cooler (0ver 10 degrees C) because of the better airflow.
I can run all of mine overclocked at 900mhz, where they all put out about 360Mhashes each, but I'll get daily random crashes. I've since dropped down to 875mhz and I have all 3 cards stable and humming along at around 340 MHashes each (with the hottest card around 83 degrees C)
Oh yeah, and this is all off of a Rosewill 750w power supply! (though I haven't checked what my actual power draw is)

hi guys! I might interest you with my cards: both 5850 reference xfx and sapphire (nonxtreme), with trixx software, btw they are crossfired, they're doing 340mhash/s each @ 900/300 1.088v. My pc would crash if i post it to above 900 without upping volts. Weird thing is, the xfx temps are way cooler than the sapphire, 58C and 68c for sapphire, this is with aircon on, while without, it's 64 then 78, the cards are loud btw. I've set the sapphire at 85% constant fan usage, while xfx at variable rate and still is cooler. I might water cool them in the future. Just sharing.
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?
79C should not kill your card, not even a reference card. It may reduce the MTBF some, but you should still be taking years on average.

Sonata could you tell what configuration of PC do you have? motherboard, CPU, Ram, etc.
Can I connect ASUS HD5850 to any kind of PCI-E? (PCI-E x 1, PCI-E x 4, PCI-E x 16)?
Can I connect ASUS HD5850 to PCI (not PCI-E)?
And 3rd question is it possible (has it sense) to connect 4 HD5850 to one motherboard (ASROCK K10N78D)?
Best regards,
M!

a) Yes, there's extenders you can buy, which also allow the ability to connect your cards to 1x ports. Mining required little bandwidth, so you don't need x16.
b) Unsure about this, I know there are PCI to PCI-E cards, but they usually cost more than they're worth.
c) Since you have 4x PCI-E slots, you /should/ be able to connect 4 HD5850 (with extenders and a nice place for each of them..

I have the exact same card from NewEgg and can only get 850Mhz out of it. My silicon bows to your superior batch 
Hi dude, my thoughts that his vga bios is rly good. He might wanna share it with us
I bought a non reference XFX radeon 5850 earlier this week from tigerdirect for $150.
I'm currently doing a low overclock with core at 860, mem at 993, voltage at 1088, fan at 70%, temp at 66C, currently getting 310Mhash/s with -v -w 128 -f 60, as I use this computer a lot I still need the graphics to be useable, lol
Anywho question is even though I have XFX the Trixx app still works to overclock however I can't change voltage still. Is there any trick/setting change to getting Trixx to change voltage? I googled and found a couple forums where people said their non reference XFX 5850s were able to be overvolted with the Trixx app, but they didn't say how.

Has someone managed to change voltage on multiple GPU with TRIXX ?
The multi-gpu checkbox might only work with crossfire or ?

It doesn't work with or without crossfire. The settings only affect the first GPU. I've submitted a support ticket. You should do the same thing.

Amateurs.
My Sapphire 5850s are doing 341 MH/s with an 852 core clock.
Recipe:
Headless linux
SDK 2.4
Use AMDOverdriveCtrl to allow low memory clocks
DISPLAY=:0.0 aticonfig --adapter=$1 --od-setclocks=852,284
phoenix.py -q 2 -k phatk DEVICE=$1 AGGRESSION=13 WORKSIZE=256 VECTORS BFI_INT
Sensor 0: Temperature - 60.00 C (though I have the fan set high)
I wrote a script to sweep memory speeds and kernel configurations to find the highest rate settings. I found that memory being exactly 1/3rd core was a big speedup for me. YMMV, if that works for you I'd like to know— I don't know if thats some chance property of my hardware or something more fundamental.
I understand that the phatk kernel is not a win unless you're on SDK 2.4
My cards aren't stable at 900. I'm skeptical of ~875, thus the 852. Next time I take an outage I'll try flashing the bios to nudge the voltage a little.

Forgot about it:

10.7 and SDK 2.2 (dunno why it doesnt want to work with 2.1)

U most likely forgot to add flags.
Can any1 check if got better results without '-w' flag?

How to overvolt a Sapphire 5850 Extreme in Linux? in windows i used Trixx, but in linux?
Thanks:)
Thanks:)
I'm surprised you are getting this Mhash/s rate in Windows. If you were able to recreate these settings in say the latest stable of Debian or the latest release Ubuntu x86_64 do you think it would be even faster?
I'm surprised you're surprised. I get 372 MHash at 930 MHz in Debian. If I could run at 1050 MHz like the other guy I should get about 420 MHash.I'm running this card on Debian @ 950 MHz. On poclbm I'm getting 317 MHash. On phoenix 304 MHash. How are you getting 372 MHash?
EDIT:
also running:
AMD APP SDK v2.4
ATI catalyst & drivers 11.3
I'm getting 360Mh/s on ubuntu. See sig
Latest drivers on Windows, clocking in at 800 mhz core / 300 mhz memory, I am getting about 295 Mh/s using phoenix 1.4. This is the Saphire 5850.
