XFX 470 8GB Invalid shares problem

[Aleventor]

Hi there,
building my 4th mining rig and I have encountered weird issue that I just cannot get rid off. Right at the start of mining, I can have settings on all xfx 470 8gb card set to 1100cr, 900cvol, 1950mem, and for a solid 60-90min miner works perfectly, 0 invalid shares, no temperature issues, nothing.
However after this 60-90min mark invalid shares start popping up on these cards. No matter the settings. I can literally change it to 1050/970/1900 the problem persists. TeamRedMiner doesnt show any rejected shares, all accepted, hashrate on pool functioning OK. any ideas? please

Update: I take it back, TRM shows HW: number of invalid shares.
Getting rid of all OC doesn’t solve issue either - even though cvol goes to 1000 on some cards

The only thing I did was change to phoenix miner, rebooted and instantly getting only good shares 22 minutes in. Gonna update when first invalids come.

47minutes in, 1st incorrect share and now it begins happening more rapidly…

Hi, how are you? I wanted to ask you if you found a solution to the problem, because the same thing happens to me with an XFX rx580 8gb with the same Hynix memory

I have almost %50 invalid shares XFX RX 480 8 GB Samsung memory. I also changed many client (Phoenix, gminer, lol) but does not fix ( with or without OC and BIOS)

Had the same issue with the same card (Modded xfx rx 470 8gb). Fixed it by keeping the temperature at 50° C. The reason you are having problems is because your card is thermal throttling. Either changed pads/paste or keep the card cool or do both for better results.

I had the same issue with XFX RX 470. Deleted --REF 30 parameter in HiveOS solved the issue. Now I have 1.5 Mh per card less but stable. My settings are CORE 1100 Core Voltage 830 Mem 2000. I get currently 28.5 Mh per card.
