Using R9 280X with modded bios and some overclocked GPU. v12 works fine. Tested over 2-3 days working without issuies.

With v12.1 only 1st intensity is most stable. With any other intensity miner after about 10 min starts to show 0 hashrates and 0% GPU load.
With 1st intensity miner works normal 20-30 min and then speed is 0 too. Miner restarts and so on.

Returning back to v12. It's stable for me.

Windows 10 Pro.
Tryed 15.12 drivers, disable overclocking. Nothing helps.
Any other miners works fine. PSU 60-70% load.

After some couple of days testing, i find 16.3.2 drivers performs better in terms of stability than 15.12,
on all my 7970/280x/380/390 rigs...
And it happens on v12.0 and v12.1 miner ... (got some strange instability with 280x rigs, and tried 16.3.2,
everything works perfect so far).

Thanks! I'll try 16.3.2.

P.S. Are you tried other WHQL versions like 16.12.2, 16.9.2, 16.7.3?

im using 16.10.2, and its fine, tried 16.12.2 and no success....

Just installed 16.3.2 testing 12.1 in progress...
On 16.10.2 7970/280x/380/390 rigs works without hangs?

EDIT: After 13 minutes of mining on 16.3.2 + v12.1 with maximum intensity GPU0 hangs (280X). Try to lowing intesity by one step.
Interesting that 270X works stable on any driver and max.intensity with 12.1...

EDIT2: Intensity 4 couses hangs 280X so as 5... Trying 3...

EDIT3: Intensity 3 also hangs 280X... Trying 2... I have feeling that low intensity hangs more quickly... 5 - 13 min. 4 and 3 - less than 5 min. Or it's random...

EDIT4: Even Intensity 1 and 2 causes 280X to hang... I think it's no a driver problem...

Ramp up voltage on that card a bit up ... see what will happen, it should work normal with -i 5

Also, take off the extender cables, clean contacts on both card and small board that goes in motherboard. Re-test.

and ... last but not least - you mentioned "modded" 280x ? Which way it was modded ? You flashed some modded bios,
that you found on this forum (bad idea), or you manually modded lower straps into higher ones ?
also, what is the card manufacturer / exact model ?

anyone have good settings for and msi twin frozer rx 470 8gb
windows 7

If you mean clock/voltages ... gpu 1200-1233 , ram 1750, voltage, depending on asic quality from -80 to -96, memory straps from 1500MHz.

After I moved one (Sapphire) of my 2 cards from "normal" pcie x16 slot to riser I get 15 H/s less on average on that card.

Also I switched my monitor from Sapphire to MSI.

Second card (MSI) which was always on riser stayed the same.

I have those blue usb 3 risers, could this be an riser issue? Or something else?

(v12.1, 15.12, oc settings same as before)

Of course, whan card is in slot, and working at higher PCI-E ratio/generation, cpu-to-gpu latency is lower, and thats why you see a bit higher speed.
