Some update to ASUS M5A99FX PRO R2.0.

Apparently BIOS might get stuck on "Extreme" VRM setting which keeps all phases on. Newest Bios and proper checking of the setting may resolve the issue. Bad thing is that these boards may be subjected to faster aging due this, good thing that the CPU was usually not on that high load.

To improve thermals on VRM i replaced R9-290x with a watercooled FuryX, NB is not overclocked in my case, so i safely reduced NB voltage to stock. Because NB and VRM share cooler, it improved stability and VRM thermals under load.

Because the CPU isnt able to go above 3800Mhz reliably it wont me much an issue.

how does changing the video card reduce mobo VRM thermals?

R9-290x is a furnace compared to watercooled R9 FuryX.

While NB cooler which is connected with VRM cooler via heatpipe is right next to it.

Hello. Is Gigabyte GA-990FXA-UD5 R1.0 good? Cause here in my country I checked different shops and they have just R1.0 and not R3.0 or R3.1? Before to ask or say about AMD FX is old story and I should change the platform to Zen or Intel, I have already PC which works good but I'm using at the moment Asrock 970 Pro3 R2.0 which is not bad motherboard but doesn't give me potencial for good overclock. Also I have AMD FX 8300 which is 95W TDP. So my questions - is R1.0 worth it for GA-990FXA-UD5? Thank You!

I have one for years now with FX 6350 at 4.9 GHz, it's actually v1.1. VRM and NB can get a bit hot but it's doing fine. Only thing it doesn't have is UEFI. Everything works as first day.

Does the cheapo motherboard Gigabyte 970A DS3P with the black PCB (only motherboard with 900 series chipset available brand new for AM3+ everywhere right now) have the same VRM than the 970A DS3 ? Phase configuration looks the same (4+1) , but no idea on MOSFETs.

i don't see the asrock 760GM-HDV, how many phases is it?

It looks like a 4+1 layout. If you're running the CPU at stock speeds it should be fine, but I wouldn't overclock with it unless you can find heatsinks that fit on the mosfets.

Where is the AM4 database for this topic?
Is it not logical to list it under the same thread heading?
