Hacked Modified Memory Strap BIOS Database for ZEC MINING!

[asusx]

hello and good day guys


got 4 gpu r9 280x

2 x 280x tri fan sapphire with hynix afr (280/280 sol)

1 x 280x asus hynix afr (260sol)

1 x winforce gigabyte elpida (275sol)

i have try to use all the given rom here...successed to flash but no changes on my sol compare with stock bios. i have oc and undervolt still same

please help since TS posible to get around 300sol per card..thanks TS and others

[batko]

Elpida is good for zcash!

I have 280x Dual-x with elpida memory default clock 1020/1500 -300+sol
moded bios
with oc i have 320sol...

hi, i've decided to take the plunge and have a go. i have two msi gaming 290x's under water. i can not find any modded bios roms for these? can anyone help? they both have hynix memory

set 1250 strap, and clock memory 1500.

Stilt's bios for ref 290x works with this card.
I flashed MBA_C6710101-100_K2_AGR_STILTMXT_V46.zip

I got better hashrate with XMR and ZEC, but  ETH mines poorly with this bios.

R9 390 1125/1625 (1125 strap, hynix):



Looks like it is somehow memory limited, 1700 (1125) gives even more hash.

Same clocks give 920 h/s on xmr and 31.3 + 313 on dagger+pasc.

Been a while since I updated this thread.

Basically with ZEC 12.2 Claymore the 7970/280x gets around ~320H/s.

His miner software improved so the hacked memory straps make less of a difference then before from stock speed.

What's disappointing is that the R9 290 runs at the EXACT same speed as the 7970. The Stilt Bios straps caused freezes and I had to revert to stock bios.

Going to play around with the Hawaii and see what I can get.

EDIT:

I got a Reference R9 290 with Elpida memory. Took the 1250 Strap put it into the 1625 and run at 1000/1625 and got 375H/s. So a little improvement. No idea if its stable long-term however.

repaste that r9 290 and you can get 1100 core out of it quite easily. at 1.1875v

i like to use the 290x rom and lower mem clocks though.

i have found removing the faceplate dramatically improves potential.

Removing the backplate makes a difference. Repasting any reference GPUs does nothing. Even repasting some AIB does nothing. Just waste of time.

Maybe the paste I used was crappy (AS5) but it made no difference on any reference GPUs that i've owned. Maybe made a difference on some AIB.

[smaxz]

not crappy but as5 is old school and has a notorious cure time to reach maximum efficiency.

i'll concede the reference cooler leaves tons to be desired but re pasting usually entails dusting off the fins and if you're doing it right.. taking care of the mosfets and replacing those terrible stock memory chip thermal pads too. this brings new life to lots of equipment, not just the 290's.

i think for the compute unit itself, gelid's GC-EXTREME is a good safe TIM.. according to manufacturer as5 has like a 200 hour cure time and requires several thermal cycles on top of that. if you have a stable rig running 24/7, cycling it with breaks to cool components just isn't practical.

[forzendiablo]

latest AMD drivers dont allow modding, they will crush windows and such.
anybody knows which is the latest driver (and bios) that we can edit and not be flagged down?

there is this big issue on the cards now

Elpida is good for zcash!

I have 280x Dual-x with elpida memory default clock 1020/1500 -300+sol
moded bios
with oc i have 320sol...

What mod do you? I have this card with elpida and it shows 300 sol 1090/1600 with 1500 strap on zec clay 12.2 win 7/64, 16.10.3

Lower core clock / Lower intensity / Raise voltage / Change riser

Replacing the crappy stock memory chip thermal pads with what, exactly?

Please provide link to a better thermal pad, or explain if you are using copper shims.

Thanks.

[dadach]

i have 2 asus 280x directcu ii, getting 280-300. what can i get with this bios?

Your speed is already fast, no more than 2-3% gain with the BIOS.

[mikecitt]

Does anybody have modded bios for Club 3d r9 280x hynix ?
