The speed the core can handle is partially dependent on the voltage it can handle. Those are easier to discover in windows than in linux. The wiki says VECTORS BFI_INT FASTLOOP=false AGGRESSION=12 WORKSIZE=256 so no different that a 5850 or 5870.

Well, the 5830 is a big downgrade from the 5850/5870 since he listed he is using a 5830.

Id suggest checking the hardware page out : https://en.bitcoin.it/wiki/Mining_hardware_comparison

The performance you get per 5830 seems just about correct for near stock speeds, perhaps follow some of the notes on the wiki pages opposite the 5830's.

So I got a few friends of mine involved in bitcoin mining... convinced them to buy a few 5830 GPUs since we can get them for about $110 USD each up here in Canada.

I noticed that when installing ubuntu with these 5830s at any clock setting (stock or overclocked) the mouse didn't show up. With or without fglrx drivers... no mouse... hrmmm???

I have managed to set the memory clock to 300 MHz and the GPU core to 975 MHz with no problems and have received about 240 MHash/sec off of each card. I was hoping for at least 250 though.. :S

Any suggestions to up the speed?

Not to take the p_ss out of your question Tongue

but you could get that extra 10mhash from mining your cpu(if its atleast semi decent one)

Just make sure if you mine GPU/CPU together to leave one thread open so that it wont cause a slowdown on the GPU. Might be a windows things but worth checking first on linux.

No offense taken!

My buddy is running 4 * 5830s on an MSI 790FX-GD70 board... works fairly well at the moment... doing about 20% better than stock speeds at only ~18% gpu core increase.

Really my question is "is there a limit to how many mhz a cpu core can acheive? or is it solely dependant on temperature?"... Huh

I will be playing around with them more over the next few days and will let y'all know.

As of right now... we're doing almost 1 Ghps on an $800 USD rig. PM me for parts/info.
