My mining averages 1700MHash/s which should get atleast 0.8-0.9 BTC / day but I only got 0.67BTC in the last 24 hours. What's happening?

2 x 6990 = 1600Mhash/s 4 x 5570 = 280Mhash/s

Quote from: Desolator on July 25, 2011, 02:02:04 AM Was that the motherboard BIOS? and a digital or physical switch? Cuz I know there's something called GPU-boost or something like that on some ASUS motherboards and I know MSI also has a physical OC switch which I thought was a really, really, really stupid idea cuz of stories like this For the unhelpful help worth approx 0.000000004 rounded (lol 9 digits...get it?) my address is: 1KM4x4mXsaTHRX2D7pKXvris4FZHVZbeaB I didn't get the addresses of my 2 most trusted assistants on this matter though: It's the Physical switch. It overclocks the core to 880. Lol nice pic!

Oh My God! I Solved it! BIOS switch at "overclocked" position 1 and worked perfectly! Thanks guys for supporting! Please give your bitcoin address so I can reward all of you who tried helping me

The crossfire is enabled by default for the 6990 GPUs. Performance on my second card is nice but the first one is minimal since clock settings are same / similar. fyi, first card uses 750W PSU, second uses 650W PSU. The PSU used shouldn't be an issue. Have you restarted the first machine since discovering this? Yes I did a couple of times.

@Desolator: I ran GPU-Z and found out the first card has crossfire disabled. image: I remembered installing catalyst control center on the first card but not second. Can ATI CCC enable Crossfire? hmm.. best to try it. EDIT: The first card actually has crossfire enabled when I selected the other GPU. BIOS version same for both.

Look at the 1st picture, and you will see, that the slower Mh/s card are running at 99% @Mezzan: Both PCs are running the same OS? Yes both are using Windows 7 64bit, 2GB RAM each PC

Good idea but that's what I'm afraid of. I'm worried if i swap the cards the 800MHash/s card will not get that speed anymore even if i put it back but heck, I'll give it a try tomorrow since it's at my data center. I'll update on anything I find tomorrow. I'll try with TRIXX as well.

6990 will not work if memory clock is 100mhz below core clock, it will freeze instead. These two 6990's are on separate motherboards, basically two different computers.

on: July 23, 2011, 10:45:37 AM

Ah yes: -v -w128 -f1

on: July 23, 2011, 10:39:02 AM

It's kinda funny the difference between these two is about 100Mhash/s which is significant. I've been testing with different core and mem clocks for the first 6990 but still similar results. INFO: - Fan speed at 60% for both cards. - FLAGS: -v -w128 -f1 (poclbm) - Brand is PowerColor. - First card uses 750W PSU, second uses 650W PSU. Any ideas what went wrong? Or is it just the card? Solution: Set BIOS switch at "overclocked" position 1
