Have noticed rx480 hashing over 400s/s when starting miner then correcting down to 320s/s seems to be opposite of previous releases,some of my rigs start with 0s/s before climbing to 320s/s so don't think we can read to much into it,running windows and stable 24 hours so far

175 => 195 on 380x stock clocks

Well you can, it just most likely will not be profitable at all.

That is right. It is better not to GPU mine dash.

Anybody done any tests on power draw for V12.1?

I woke up to a partly burned 6pin.

inb4 "stop blaming Claymore hur dur"

I am using Aerocool 1000w on x2 390 which is know is a pile of shit for mining

Already fucked 2 of the 4 pcie power cables with the same issue but this was due to overclock.

The issue is I now, after the above situation, set a heavy powerlimit restriction and undervolt which was fine through V9->V11

Looking now to either mine the PSU to death or sell it in a couple of months.

Anyone else stupid enough to buy Areostool PSU and could share experience?

Doesn't account for damage.

Aeroshit must be on its last legs

Thanks

Hmm so I can confirm there is some weird stuff going on with claymore v12 and polaris hash reporting. First shot is claymore 24h average v12.1 right before I switched to optiminer 1.6.2. Second is optiminer after 24 hours. 

Claymore reports exactly 2804 average hashrate miner side which should equal ~2750 poolside after dev fee is taken out. Poolside reports over 100mh less than that though.
Optiminer reports 2734, which is exactly what pool is reporting at 2731

Whats more interesting is that Claymore on a 280x rig reports the exact hashrate minus fee that the pool reports. At first I thought this was either a pool/hashrate bug issue, but the fact that optiminer reports the correct hashrate, and the 280x rigs report correct with claymore.

My guess is that either there is a bug with polaris hash reporting (i hope) or he couldn't reach optiminer performance on polaris, so he bumped his numbers by 5% to make it look like his miner is faster
