Asrock 990fx extreme3 vrm throttling

[nrallakis]

I have an amd fx-8350 cpu, my vrm overheats and throttles..
I there any way to fix this problem?(e.x. Maybe adding custom heatsink?)

1) Disable one, two, or three cores in the BIOS until the PC runs fine.
2) Like you said buy the custom heatsink http://www.frozencpu.com/products/7190/vid-105/Enzotech_MOS-C1_MOSFET_Heatsinks_-_65mm_x_65mm_x_12mm_-_10_Pack.html?tl=g40c16s1861
3) Buy the new MB.

What motherboard do you suggest for overclocking to 4.5ghz.
P.S I have a very tight budget...

Gigabyte GA-970A-UD3P or Asus M5A97 EVO R2.0, or MSI 970 GAMING ATX AM3+, if you can buy the 990 chipset AM3+ then they are the best one. Like Asus Sabertooth 990FX R2.0 or Asus Crosshair V Formula-Z but not the Asrock 990fx extreme3 or Gigabyte GA-990FXA-UD3.

Is there any major difference between 970 and 990 chipset?
I'm thinking of getting the msi 970 Gaming...

The msi 970 Gaming is good one. The 990 chipset is better for OCing with higher quality components and multi GPU support like sli or cf. Most of 970 MBs can only CF, but msi 970 Gaming can sli and cf too.

All I want to do is a stable overclock at 4.5ghz. Is the msi 970 Gaming capable of this small overclock?

I don't have this MB, but from one of review, you can use it oc the fx8350 to 4.5ghz with the good aftermarket cpu cooler.

Thank you very much!
I will buy this msi motherboard.
Just to let you know, I have a CoolerMaster Seidon 120V watercooler...
