"ASUS issued a press-release in which they announce d that its existing 990FX-based motherboards all support the new flagship AMD FX-9000" What about the first released Sabertooth board??

the FX-9000 Series requires incredible amounts of power and generates considerable heat - AMD recommends a 1200 W power supply and liquid processor cooling.

1200w PSU 😱, lmfao 😀

these cpu's are way overpriced anyways your better off trying to oc the 8350

For ASUS motherboard to fully support that Power-Plant-Eating-Monster out of the box brings 2 concerns for thought. Either ASUS Mobos are way more outstandingly/exceptionally better when compared to competitors OR the competitors Mobos are really, really lacking in quality for them to not support the CPU out of the box. Hmm..... And no, it might look that those 2 concerns are the same/similar but they are far from it. But since it requires just a BIOSes update, it meants it just a software-hardware related thing. Edit: Maybe ASUS just had support for 5Ghz/1.5V+/250W support already integrated in the bios while others had to issue an update to make those changes/support. Probably that why the straight support.

Sabertooth 990FX R2.0/Gen3 R2.0 and Chrossair Formula-Z support those 220W CPUs, the M5A99X EVO R2.0 and M5A99FX R2.0 are listed as supported, so it will work, but will pretty much fry the VRM's in a couple of months, they have only 8 phases vs 10 on the Sabertooth R2.0 and Formula-Z, and half the VRMs (no vrm's on the backside of the motherboard), I have the Sabertooth R2.0 and when overclocking to 4.7GHz with 1.45V I can't keep my fingers on the VRM's radiator on either sides of the motherboard they go to at least 90C, put that on 8 phases, half the VRM's and not that good vrm cooling and you get the ideea....

2400Mhz Ram supported. Hmm Thought it was only rated at 2133 oc

one of the worst CPU i ever seen. if u don't wanna get i5/i7, just get 8350 and oc, way better same performance

^That's what I was thinking. lol

OK well Sabertooth only has 8 phase for the CPU, the other 2 are for DRAM and NB. 90c is OK and the Fet's come with OTP and OCP but they shouldn't get that hot anyway unless you're running P95 or something. What are your Digi+ BIOS settings?

Officially 1866 but "official" doesn't really mean much.....:P
