Hello
I'm using 2 old RADEON 6950 on 2 different computer. It's the 1st miner could hash from the Monero V7 fork and I'm happy to discover this miner!

I have a hashrate problem, I can't reach better than 145 H / s. Before the Fork I was doing 350 H / s with this card with other miner.

I've tried the automatic intensity, and a lot of between 0 - 300 i've got the max with intensity 15
Is this card compatible with this miner ? Already it is stable and there is HASHRATE. Which is not the case with any other minor i've tried ...

I hope you could help me with my 2 old radeon card.

I'm Using Windows 8.1 X64
The last WHQL Driver for this card "15.7.1"

There is some recommendation about the driver revision or other tips to Hash more with that card ?

Thank you for your work

@doktor83

I quoted myself

Any idea about this card ?

The blockchain driver did'nt work and the laster beta drivers didn't work too.
So only the WHQL 15.7.1 driver works at low hasrate.

Since the hard fork claymore doesn't support older card than 6xxx, i think u have a lot of old miner could be interested by your miner, i saw same problem on other forum as mine with this 6xxx card can't hash, SRB Miner is the only one could hash with my card.

I hope you could help me.

The blockchain and latest drivers won't work with this card because it is a pre-GCN card. Probably need custom timings in BIOS and overclock memory to get better hashrate.

Ok and what about the hasrate 350 before hard fork ==> 145h/s after ? Sad

I know it's a very oldcard, but 700h/s on two card was prety good for those grandma Grin

i'm at the maximum OC AMD Override let me put : Gpu 800@840 Memory 1250@1350, Memory speed didn't impact the hashrate. It's seems the miner didn't take all the GPU "powerfull"

Which miner did you use previously? Probably better optimized kernel or something to give better hashrate. SRB probably isn't optimized for older cards, maybe try with XMR-STAK?
