Thank you very much for this information. I now know what you meant by all those VRM comments on my threads. tongue.gif

I'll definitely use this information when picking out a motherboard.

Here is the thread with the details and story.
http://www.overclock.net/power-supplies/1130088-did-my-power-supply-just-die.html#post15132136

AMD X6 1100T, OC at 4.0gHz with 1.408 volts.

Got that in before it crashed.

Personally I would like to see the 970A-G45 reviewed... apparently it uses 4 transistors per phase apart from the normal 3 now, doesn't make much sense... though I doubt anyone's going to buy it if it remains at the current price on Newegg (not very good price-performance)...

I've got a 970a-g45 on the way to replace an 890FXA-G65 which seems to have crossed BFG830's 12v streams when some stray voltage came in. I named it O.B. Lan Kablooie. Was a fairly impressive stray charge, it ate my cable modem too.

I was running a 1055x6 stable in an older msi 870-35 using old VGA sinks, the heat seemed to be the only real problem. You'd be surprised how many truly tech savy people, even on this board, have no clue how case ventilation works.

newegg seems to think the 970a will hold an x6 and I put a $10 on the tab to make sure they have fun with the chad if it won't. So we'll find out We or Th.

Shame to lose the BFG... it'd push 12.9 at 650w all day.

Today we have the first recorded 970A-G45 failure
Looks like the problems of the previous gen were passed on to the next gen, just as I had suspected. How is a massive heatsink going to help when the same transistors and lack of protection are being used...

I see a MSI 880GM-E41 is listed here which is the board i have. I'm a bit surprised to see some one attempted to put a (edit) 125W 1055T in this board considering it only supports <= 95W CPUs & it points to this link as evidence of failure: http://bit.ly/mFiGX2

I guess it shouldn't be so surprising it failed. This board should probably be removed from that list if its based upon that newegg review/failure.

Actually no, it's still MSI's error, as they list 1055T as supported, but as 95W also, and as far as AMD official data goes, 1055 doesn't have 95W version, 1065 does.

http://www.amd.com/us/products/desktop/processors/phenom-ii/Pages/phenom-ii-model-number-comparison.aspx

So according to MSI, that mobo supports that CPU.

So according to MSI, that mobo supports that CPU.

In the list of CPUs supported for the 880GM-E41 (on MSI's website) the 95W 1055T is listed, however in the list here says a 125W 1055 was used in that motherboard. Which was never supported.

"4/4/2011MSI 880GM-E41AMD Phenom II x6 1055T [125W]OverclockedStockhttp://bit.ly/mFiGX2"

http://www.msi.com/product/mb/880GM-E41.html#/?div=CPUSupport

I've personally never been confused about whether or not my motherboard supports any 125W cpu. The supported CPU list is clear about only supporting <= 95W CPUs

^ Trust the more updated 95W rating. It is at least in line with GIGABYTE and ASUS's ratings for their 3+1 phase boards.

im going to book mark this glad to see my Foxconn A6GMV is not up there this sucker took 1.62v for my max OC on my athlon
post #910 of 1100
I probably did a really good job of skipping over the obvious answer...but...

Would all of this mean that the ASUS Crosshair V, with it's two CPU power connectors (8-pin and 4-pin), would be the best for overclocking?
Or
Would the ASRock Fatal1ty 990FX be better for overclocking because of the 12 + 2 design?

Thanks and sorry for derping doh.gif
