Re: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

Ok I'm ready to burn my computer. Someone please help me. I have a R280X that runs Cryptonite at 485h/s and according to the charts should run Equihash around 290 h/s. I'm running claymore 12.6 on Slushpool and when the miner starts it does 275h/s. It then begins to throttle down in steps down to 145 h/s and sometimes lower. I recently watch it go as low as 40 h/s before climbing back up to 145 h/s.
Does anybody know why the rates are so low, and also the -i and -il commands do nothing to the hashrate.
I'm running the "blockchain" drivers but had the same problem when running AMD 15.2.
Any ideas?
Bob

Which GPU is this exactly?

Most likely your fans are dead or dying and your GPU is throttling.

Then why does it run full guns 485 h/s when mining cryptonite ? no problem there...only problem is equihash and claymore 12.6

What Is the make and model of your 280x ?

Try using the older 15.12 drivers and set clock to 1050/1500 or so.

I have a few 7970 (280X), I run them at 950 mV, 900/1250MHz, quite stable.

I am also running a few 7970 aka 280x, @1050/1400 1110-1150mV (depends on the specific card) and making with a modded BIOS ~300+ Sol per card. If the -i setting does nothing, then something is wrong on your side, mine 280x' run stable with i 4.

I run -i 4 or 5, quite good. little incorrect shares.

Those clocks seem tame for 7950/7970/280x. The reference 7950s I have that aren't dying on me run 1475m/1225e and hash 315 s/s (according to Claymore's) stable. I was 290-300 sol/s before Adaseb hooked me up with newer bios timings ... I hadn't updated the bios since I undervolted for litecoin. I've also got them juiced up pretty good these days at 1.2v because my energy costs permit it, but they can run 305 sols right at 1.01 volt if i recall.
