let's me try it once

please give me screen whit stable work memory clock

as you wish

how you did it ((((

I told you but you didn't believe in me

i have many R9 290 and 290x and all non stable memory clock !

I think you should try to install newest driver from ATI download page for the last time. 13.12 it isn't stable with 290 and 290x

How many 290's are you running to get 1300+h/s?

[deathchuck2]

How many 290's are you running to get 1300+h/s?

Oh man, you can count and you will find that not 290's LOL

[nrg_wolf]

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.

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

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

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

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.

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

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

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

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?

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
