any thoughts on how to get 280x's stable with this gpu miner yet?

and why gigabyte 280x's seem to suffer very low hash rate, eg struggle to break 300h/s when compared to an asus 280x that does 360 with ease.

That's what you mean ? Gigabyte like my another rig ?

are they the windforce 280x's rev 1 or 2?

i run 2 of them and one can do 310H/s at 1200/1500 and the other does about 308H/s at 1200/1500. cant seem to push them any higher on mine. even tried different motherboards and the same affect, they are also the ones that drop out 98% of the time....

R9 280x Windforce Rev2. I do it with default clock 1100/1500. Stop OC your CoreClock cuz it will not stable and increase very little hashrate compare with power consumption. I suggest use default for best performance. If you want to OC, just increase a little with MemClock. FORGET TO OC CORE, IT'S NOT GOOD AT ALL.

Cannot confirm your experience with overclocking. My Rig has been running stable with 1140/1800 clocks for 28 hours now. Each 280x toxic is hashing with like 360h/s.
Don't know about changes in power consumption, but I don't really care cause its free anyway Wink

mine also does not have Hynix GDDR, i have Elpida, which iam assumeing is a much poorer quality brand of memory. i will knock back the OC and list the results.
do you have stock bios, or modded bios btw?
and do yours stay at 99/100% usage or do they bounce around alittle?

Edit.
both cards running at stock clocks with only +20% to power, one does 292 and the other does 288h/s.
very low considering my asus 280x both combined do 730H/s :-/

I get periodic disconnects from mining, at which point I have to manually restart. It would be good if the software could be updated to detect this and automatically restart. Also, support for multiple pools (i.e. failover) would be helpful. Last but not least, optimizations to performance are almost certainly still available. Are there plans to open source this eventually? Or do we just need to wait for ccMiner and sgminer to create their own Cryptonight code?

disconnects has nothing to do with the miner. monero.org and. fr having ddos attacks since yesterday

It doesn't automatically try to reconnect? I have to restart the pool sometimes (often a few times a day) when the daemon gets stuck..

If i'm not wrong, you're using port 80 as default as pool recommended ? Forget that port, change to another port like 5555 (moneropool) or 6666 (crypto-pool.fr), it will work well with more hashrate accuracy than port 80

I see same thing on 290, and clock is stable on 280X. Some algos don't use memory heavily so driver reduces mem clock, it must not cause less mining speed if driver knows what it's doing. The questions is why it reduces clock for 290 only.

Because the power saving features on R9 290 are more advanced than in previous generation : the gpu and mem frequency are fastly adapted to the present charge.
For X11 mining (before recent optimizations), I obtained some minor performance increase with disabling this power management behaviour : in MSI afterburner, using unofficial overclocking with disabling powerplay : this forces always max clock.

for 290 and 290x not work for monero disable powerplay whit MSI all time crashes driver for x11 no need optimization MSI nice hashe whithout MSI... 4300-4400 for x11

jumps every second memory will not affect the wear of equipment ?

DEV please help.. how fixed memory clock on 290 and 290x

what issue are you having with the memclocks?

all 290 and 290x have look pictures.. http://fotki.yandex.ru/users/aliaksandr-kavaleuski/view/1148794

every 0.5 seconds memory frequency from 150 to 1300 non stop.. i have 6 rigs whit 290 and 290x all have this problem

I see this as well on my 290 rigs.

you look link on pictures ?

Yes, I see the memory clock jump back and forth between 1300 and 150 in gpu-z.

need help DEV
