Hello everyone!

Does this miner support TeraScale/VLIW Radeon GPUs?

it should work, but you wont get speeds like on old claymore.
Which card do you have?

Radeon 5770 1GB GDDR5.

And yeah, hashing speed is only half compared to Claymore v9.7...

download v 1.4.3 and add --usekernel 3 in the bat like this :

%EXE% --config config.txt --pools pools.txt --usekernel 3

this is a test kernel im working on for those oldies

I guess this emulates the Claymore v9.7 kernel?

Thanks for caring about old GPUs (most devs don't), I'll give it a try!

I just tried it and I still only get 80 H/s compared to 176 H/s on Claymore v9.7... intensity is 14 (higher doesn't work), worksize 8, 1 thread.

Another problem with all miners I've tried (except Claymore v9.7) is that there is no "low intensity" option, which means the UI is lagging a lot (if you want to use your PC while mining).

I wish someone could replicate Claymore v9.7 characteristics and I'd gladly pay a mining fee...

can you download 1.4.4 now and try again with --usekernel 3 parameter in bat, but set start intensity to 10 , and use only 1 thread. Then work up the intensity as much as you can.

I don't mind the devfee, as long as the miner can work as good as Claymore v9.7.

I tried intensity to 10, 67 H/s only, then I increased it to 12 and the entire PC froze. :\

I don't understand why GPU mining it's so hard compared to CPU mining where you just set the available CPU cores...

Radeon 5770 (Juniper) has 800 ALUs (10 Compute Units x 16 SIMD x 5 ALUs).

I don't even understand what intensity is supposed to do ALU-wise... why not allow us to set ALUs manually?

Claymore uses hashcount option and optimal value is 320 hashes (320 ALUs?), 2MB each = 320 x 2 = 640MB of VRAM needed. The GPU has 1024MB of VRAM, so I can still use the PC while mining with no lagging.

Is it so hard to write proper VLIW assembly (from what I've heard at least) and only Claymore has mastered this art of programming? Just wondering...

hi DOK, I get 320 h/s and with claymore 9.7 360 h/s, both results with OC, excellent work, a little more and you get over it, congratulations. (DISCUSS MY ENGLISH, I USE GOOGLE TRANSLATOR JAJAJAJAJA)
