Does anyone experience random (in time periods) total system freezes on Claymore 10.3 on Win 10 x64 (Aug 23 blockchain drivers with 3 x RX570 and 1 RX470)?
So only reboot via mobo helps.

So far the most I got it running without freezes is 48 hours, but it can freeze in 2 hours or 10 or x hours.
There's nothing in Claymore or Windows logs.

I've experienced exactly the same behavoir when mining XMR with Claymore's Cryptonote AMD Miner v11 - but not on v9 or v10 - they were quite stable.
My cards are BIOS moded, overclocked in memory, downclocked in core and core voltage - last few days I'm bringing each card 20 MHz down after another freeze trying to understand if it could be related to memory - so far got to 1960 MHz.
However, I think if it was to do with memory - I'd get memory errors (which I don't) and/or general GPU drivers failure or single/multiple GPUs hashing stops - but it just freezes whole system. Quite frustrating tbh.

Btw I have 32G of page file, so virtual memory shouldn't be the cause.
I could try Claymore dual miner v10.5, but something tells me the freezes won't go away :/

First of all, something telling you isn't factual, so you might aswell try 10.5 Wink

On the other hand, I remember that AMD fixed a bug regarding freezing systems in multi-gpu systems. Try the latest Adrenalin driver (18.1.1 or 17.11.1), those are working fine for my 12xRX580 rig.

Next to that, if you don't wanna upgrade drivers, please run at stock settings, so stock voltage and mem clocks just to make sure it's not your cards failing.
