i think these cards vrm themps riddiciolus.

The vrm is only 3 phase for the gpu unfortunately. That's why extra precautions have to be implemented when increasing the voltage. It should of been 4 phase minimum.

How to get 2000Mhz in mems like a MrMaxout on PowerColor 7870EZ? What driver version do you use now? Will new drivers impair her performance? Because are optimized for seriesRx 200/300

2000Mhz Memory?
I think you would have to be supremely lucky to get that much plus do a hard mod to give memory more voltage. Maybe also looser timing to reach high Mhz. The best i managed was ~1650Mhz and even so it was benchmark but not game stable. Besides faster VRAM translates into very small gains in terms of actual performance (case in point: 1st gen HBM on Fury X).

Nope. Just backup your current vBIOS.

BIOS .32 stop core clock down to 925mhz in games?

No. They only way is to mod vBIOS with VBE7 and disable "boost" feature and set a constant clock (like 1000Mhz). Othwerwise it will still drop down to 925Mhz occasionally.

Or set 8% + in Power Limit? In page 1 say to flash a .28 or .30 bios to stop

2000 Mhz mem? What? Doubt my 290 X lightning with extra voltage on water could even do that. Probably crap out at 1700-1800.

Look the first page, in owners list.

I have problems to overclock. If i set 985 mhz or more in core clock, in games or benchmarks after few seconds, is switching between 634, 704 etc. I had the .31 version now updated to .32
