Getting ~226sol/s with sapphire hd7970 ghz (1150/1525), peaks at 235sol/s, modded bios and claymore's v8 (-i 6)

[oslak]

@adaseb, pls post your clock settings on 280x 7970's and 7950's. tnx!

[adaseb]

With V8 everything is a mess. I had to revert most of the Gigabyte 7950 7970 GPUs back to stock because I kept getting incorrect shares or the speeds kept dropping. The ASUS 7970 and 280x seem fine but not much faster then stock bios it seems.

I think for now just stick with stock bios.

[king_pin]

+1
No difference on 7950/280X
Can anyone report if there is a difference in 290/390X

[oslak]

The toxic keeps crashing at stock but flashing an asus bios seems to work but at lower settings. hashing at 200 atm. Can someone with 280x toxic post his modded bios. thanks.

[adaseb]

My most stable cards are the ASUS 7970 and ASUS 280x.
7970 = 1100/1575 = 220 H/s
280x = 1060/1600 = 220 H/s

Both use the modded bios above, however in the Claymore forum people are getting the same speeds at stock bios.

[jelin1984]

any mode bios
for

asus 470 4gb?

My most stable cards are the ASUS 7970 and ASUS 280x.
7970 = 1100/1575 = 220 H/s
280x = 1060/1600 = 220 H/s

Both use the modded bios above, however in the Claymore forum people are getting the same speeds at stock bios.

Cant replicate those hashes. Highest i get is 201. higher clocks yield nothing but crashes.
I'll try to give it more power and see if it gets better. tnx

The 280x is undervolted to 1.075V, don't remember the 7970.

Hello!
Plz modify my BIOS MSI 280X 6Gb Elpdia EDW4032BABG
https://mega.nz/#fm/HFsWRKDS

[nitromining]

170h/s on a reference 290? I'm seeing 200 at 1030/1250 -100mv with the stock bios, if I go to 1100/1475 it just eats power for an extra 10h/s.

Reference 290 can hash at 230 h/s @ 1100/1450 with Stilt BIOS mods.

More with Hynix mem
Even more with 290X.

With V8 and the 390X bios i'm now at 280-290h/s. Haven't checked watts yet.

This is the strap present on sapphire toxic trix. Identical to the strap below from modified asus bios.

The hex are identical but why cant the stock 1150/1600 1.256V on toxic reach 220sol/s. (@ 201 -207sol/s only)
I settled at 1010/1375 at 1.018V hashing at 195sol/s.

The hex are identical but why cant the stock 1150/1600 1.256V on toxic reach 220sol/s. (@ 201 -207sol/s only)
I settled at 1010/1375 at 1.018V hashing at 195sol/s.

Same memory type?
