Would the mosfets still crap out even if i can keep em cool?

It'd probably do reasonably well with watercooling on the VRM mosfets, just keep in mind there's probably VRM mosfets on the backside as well. I'd be extra concerned about those.

Thanks! I'll make sure i have a look at the back of the
board when i rebuild. Maybe i can mount a slim fan behind the mobo tray or use some ram sinks.

There's always the option of a lower binned fx and oc untill i hit the wall too. I'd save some cash, but it just doesn't sound as fun as one of those non-practical beast 220w cpus tongue.gif

Well, a couple of posts back i asked about using some heatsinks for my vrm, and well here is the result, just wanted to share:




I used an old pentium 166 heatsink and a hacksaw. It worked fine so far, i still have to change the stock cooler, but for now i am quite pleased.

I just added these through the list with the information I found and hi I just registered here


Biostar TA970 Plus = 4+1 phase analog/hybrid, doubled, <140W continuous (estimated)
GA-970A-UD3P = 4+1 true phase digital, doubled (same as 990FXA-UD3 V4.0 & V4.1), < 140W continuous (estimated)
ASUS M5A97 Plus = 4+1 true phase analog, < 95W continuos (estimated) - NOTE: (don't use with any FX-8K series)
ASRock 970M Pro3 = 4+1 true phase analog, <95W continuous (estimated)- NOTE: (don't use with any FX-8K series)
ASRock Fatal1ty 970 Performance = 4+1 true phase analog/hybrid, doubled, < 140W continuous (estimated)
ASRock 990FX Extreme6 = same as ASRock Fatal1ty 970 Performance

So the new 990FX E6 is worse than my 990FX Extreme4? How good is the VRM at the 990FXE4 anyway? Could you please tell that?

990FX Extreme4 is not better than Extreme6 but rather equal.

Extreme4 has a hybrid 2+2+1 phase VRM which has been doubled.
The controller on it (L6717A) supports 2 phases (CPU) with the internal drivers, 2 phases (CPU) with external drivers and single phase for the NB.
Each of these five phases have then been doubled which makes it theorectically a 8+2 phase board.
Unfortunately the doubling appear to be made by using the fake phase scheme, which means there is no actual hardware for the doubling (i.e. drivers supporting doubling).

Okay thanks!

Another question what would you choose for slight OC in the AM3+ market with around 100€ for a mainboard?

ASUS M5A97 EVO R2.0 - Has a 6+2 phase fully digital VRM. The six phases for the CPU are real, native phases however the CPUNB phases have been doubled by using a proper hardware for the purpose (double driver / doubler). The CPUNB phase count has never been a issue as the NB and L3 cache consumes less than 15W of power even when overclocked. The board can deliver up to 180W of constant power (estimated) when some additional air flow is provided to the VRM heatsink. When the VRM is being properly water cooled the board can support FX-9K series CPUs (220W) without any issues.

The board also has fully digital two phase VRM for the memory.

In Europe the board is available for around 94 euros (99 USD) with the VAT or sales tax of 19% included.


ASUS M5A99X EVO R2.0 (in Europe 120€ / 127USD with 19% tax) and M5A99FX PRO R2.0 (in Europe 139€ / 147USD with 19% tax) have identical VRM configuration, however they are significantly more expensive because of the additional features.


Gigabyte GA-970A-UD3P - Has 4+1 phase digital, doubled VRM and relatively high quality power components (inductors, fets and capacitors).
All of the available revisions of this board (up to date, Rev. 1.0 & 2.0) are good!

In Europe the board is available for around 76 euros (80 USD) with the VAT or sales tax of 19% included.


Gigabyte GA-970A-D3P - Has 4+1 true phase digital VRM and relatively high quality power components (inductors, fets and capacitors).

In US the board is available for 85 USD (NewEgg).


Gigabyte GA-990FXA-UD3 - Has 4+1 phase digital, doubled VRM and relatively high quality power components (inductors, fets and capacitors).
Only Rev. 4.0 and Rev. 4.1 boards are any good the rest are crap, stay away from the older (< Rev. 4.0) ones!

In Europe the board is available for around 123 euros (129 USD) with the VAT or sales tax of 19% included.

Hi All, need a motherboard to go with my Phenom II 965BE, MSI 970 Gaming or Asrock 970 Fatal1ty? Or others?
Currently using M3A97-T Deluxe. Going to do some overclock and gaming mostly. Have Swiftech H220 as cpu cooler.

Thanks
Eric
