4xSapphire 5830's/ machine (3 machines)
960/320 AOCLBF overclocking
311MH/s Stable
Stock Voltage
Trixx just to set fan speed
2 of the machines actually have an additional 6950 (975/340 360MH/s) for a total of 5 cards/ machine
Topic: 5830's, what mh/s are you getting? (Read 7652 times)
using phatk 1.50 latest version and 11.7 am getting 352 mh/s at 1029 mhz by 315 one one and 342 - 345 mh/s on anoter at 980 by 300 at stock volts .... both sapphire xtreme / trixx ok .... 1 trick I tried all the possible aggresion settings and came to conclude that aggresion 7 is far better than 12 or 14 I was using ... ( on the high revved card only used to get 328/ now well over 350 )

my 5830's running at 343mhash/s clocked at 1060/370 stable and temps don't go higher then 56ish
I'm at 1040/300 and getting 330mh/s. I can still do a few kernel upgrades and I think I can keep increasing the freq.
Yea I will I think the highest any one posted was 345 back in july. That was 1080 mhz / 380. I bet you could easily get 350 now if you tried but I definitely wouldn't keep it that high for an extended period.
331Mh/s @ 1025mhz GPU, 360mhz mem, 1180 voltage. Make sure your phatk kernel is up to date because each update made to phatk adds a significant performance boost to your hash rate!
Good luck, and also be careful! Those sound an awful lot like famous last words!
I wonder how high I can push it

I plan to make an attempt for the 5830 record later. Right not they get around 335 for 1030/350 on stock voltage. I wonder how high I can push it
I'm currently running 990/300 with 1163mV (stock) and getting 316mh/s.
Still need to modify the kernel to get a few more out of it but I'm going to guess at this point I'll hit 320mh/s no problem and may even be able to go higher.

I got one of those "Xtreme" edition Sapphire 5830s from NewEgg (one of the $109.99 dealies). I think in order for them to be "Xtreme" they have to have really good quality cores to handle the slightly higher clock rate. As a corollary this means they can be pushed to slightly higher OC levels as well. At least I *think* that's what "Xtreme" means. Or it could just all be marketing hype.
The only thing that makes the Sapphire "Xtreme" is that it has a better cooling system and some voltage tweaks that will let you overclock with better stability. Other than that, everything is EXACTLY the same as the non-Xtreme version. Same hardware, same clock speeds etc
I wouldn't go for the Sapphire Xtreme (again)... I have one, and my ASUS DirectCU can clock MUCH better, and stay much cooler than the Sapphire Xtreme.
Also, the ASUS has a much quieter fan than the Sapphire to the point where I'm not exaggerating when I say that my brand new Sapphire is twice as loud as my 10 month old ASUS.
And no, the heat isn't because it's above the ASUS because I swapped them and was getting the same high temps.
Edit: Oh yeah, what Xtoro said too. I'm using AMD GPU Clock Tool to set the MHz, and it automatically pegs the voltage at 1.025 or something like that. I have no control over the voltage with that tool.
Try using TRIXX, works for me on both cards quite well.
Doing 320 in all 3 of my sapphires. Trixx now allows voltage adjustment on multi card setups
Just got this updated kernel (http://forum.bitcoin.org/index.php?topic=25860.140)
Lowered my clock to 958mhz and I went from 304mh/s to 307mh/s.
Small increase but an increase nevertheless.

Using Trixx or MSI afterburner, are there any risks that could void a warranty? Any way for a GPU mfg to check the previous settings or anything on the physical card itself?
i have the xtreme version and using sapphire trixx but it artifacts and just generally crashes above 965
It's probably just luck of the draw. I have a couple 5870s that are the polar opposites of each other when it comes to OC'ing. One gets fussy at anything over 980. The other one can chill at 1050 all day long.
what are the other settings at that 965 mem/volt what about the temperature?
try saphire trixx i had good results at 1025mhz with that same card(and 300mhz memory)
I'm running right at 315 MH/s @ 1010/300. I could get it up to around 325 MH/s by going to 1040'ish but I don't want to push the card that hard.
what? my core is unstable over 960~
what are you doing?

Try upping your voltage a smidge. Just keep an eye on the temps

I just dropped memory clock down to 300 and I'm now getting 301-304mh/s.
