Topic: Record hashrate for a 5850? (me, showing off) - page 7. (Read 15271 times)
I am able to get around 408 at 970 but my VRMs run too hot (since I have to up the voltage a bit). I have an old Twin Turbo (non-pro) in place of stock cooling but the stock ref plate isn't very efficient for the VRMs.
How do we know you are using 5850? My miner working at about 285 can solve 6 hashes in under a minute sometimes (luck). Your 408 took 1.25mins to solve 6 hashes. Those numbers translate (I realize luck has a lot to do with it)?
I doubt it would work for more than 5 minutes (or 10 min if you're lucky) at full load without a BSOD. 1 GHz is a a 30% overclock.
Do you know any O/C software which would allow to overclock HD 6850 and HD 6850? I also need voltage change option.
On msi afterburner I can't change voltages.
On ati tray tools - only HD 6850 (my 'main' GPU, used also for gaming) is detected, 5850 isnt.
On trixx - same as ati tray tools.
In CCC I cannot change voltages.
I know I could modify and flash a new BIOS, but I would like to avoid doing that.

I managed to overclock to 1000 Mhz with default voltage, but I'm guessing this isn't particularly stable. I went back down to 775 Mhz again after a few minutes, didn't exactly feel safe to overclock that much when I barely have any experience overclocking. 
What was the default voltage, OP?
I can only get 805MHz stable. @900 (without voltage increase it's not very stable :/ ~350 Mhash/s though)

Private Beta? 
I *think* I would have beat it without the kernel optimization that bitless posted a few days ago (3% speedup for everyone), but that plus the new private 1% opt I'm trying tonight makes it feel like I'm cheating a bit
Even still, I know it would have done 400 MH/s with the old kernel that everyone else was using

According to the official comparison, 392 MH/s was the previous record, so you did beat it. Good job!
I got my reference 5850 up to 1.200v and 1020 MHz, which yielded 404 MH/s, but the VRM got too hot for my liking, a bit over 100C!
Hey guys, I've had a few people say that my 400 MH/s hash rate must be a fairy tale, I wanted to post a pic eventually, but now seemed like a good time to post a pic of 1000 MHz core with a private beta phatk kernel , my highest hashrate yet!
I'm too scared to go over this voltage, I don't want to push it too far
What is the current record for a 5850? (or at least, one on air/reference cooler)
