So I am rebuilding my PC due to issues I have had with it for quite some time. I have an AMD FX-8350 based system, and unfortunately the motherboard I chose (Gigabyte 990FXA-UD3) was the revision 3.0 board, which had VRM overheating and CPU throttling issues. In addition, my power supply's 24-pin appears to have one of its pins burnt out (Corsair HX 750). Apparently this is from too much PCI power load?
I am planning on replacing both the motherboard and the power supply. I am trying to decide between another Gigabyte board, (a revision 4.0 or higher) as the newer revision apparently have fewer issues, or an Asus M5A99FX Pro. I am also trying to figure out how to prevent my PSU's 24-pin from burning out in the future (I already RMA'd the Corsair PSU once and the issue returned on the new one after a matter of months). My system currently gets constant kernel power failures, and I have been less than happy with the motherboard, so I figured I might as well replace both. I am once again shelling out a great deal of money on this system, and I need something STABLE that's going to last for at least 5 years with no problems. I only moderately overclock the CPU (around 4.4GHz). Any suggestions for 990FX boards and 850W PSU's?
In my experience burnt pins are a result of shorts. High power draw in normal circumstances should never cause that, but I suppose crappy VRMs could be the cause. Personally, I stay away from gigabyte. Not saying they don't have a good products, but I think there's better options.
I have the ASUS Sabertooth 990FX R2.0 board linked above and a Corsair AX760i PSU. Both have been working great with my FX-8320 @ 4.8ghz and BIOS-modded R9 290X for about 2 years now.
I'm getting my OC at the same 1.4V, which either reflects the capability of the power delivery on the Sabertooth 990FX, or that I got a decent roll in the silicon lottery. The M5A97 EVO isn't a bad board by any means. I can push this chip to 5.0 at 1.48V for benchmarks but, with an overclocked 290X in the same cooling loop, it heats up more than I'd accept after a few hours of gameplay.
Mildly amusing side note, I had FX-6350 when those first came out, and got it to 4.9ghz stable on an M5A97 LE R2.0....at a monstrous 1.56V. To my surprise the chip (and board!) lasted for months and even went on to be sold later. I've had nothing but a good time with ASUS boards.
I don't think it's the board, I just fell through the silicon lottery, that's all. I will have this till next year, and then I will go either Intel or AMD. Hope that Zen will be close to intel, if not then fuck it.
