Just finished the ASrock sheet.

Damn they have a lot of boards

AM2+ Board
Gigabyte GA-MA78G-DS3H (Rev 1.0)
3+1 Phase
3 transistors
Non Low RDS MOSFETs
No VRM heatsinks
ATX form factor
4-pin CPU plug
CPU TDP limit: 95W

*note
Mine has horrid voltage accuracy (actual voltage would be higher than BIOS settings. 1.325v becomes 1.375v, 1.375v becomes 1.42v...etc)

You would be surprised how many times a day we get asked this.

There is also other information such as the quality of the phases

It's something meant for you to go back and refer to not just for choke count but overall quality, TDP support, etc. After all sometimes I'm tired of having to go back to Newegg and have to load bandwidth-intensive for that motherboard (UBB for the lose)

On the other hand... ASUS, Gigabyte, MSI, Biostar, ASRock are all done

Yea, we were both shocked when the asrock site said 125w.

140w would be sad

Thank you very much for this effort. Very useful!

Question about the low RDS(on) column ... how do you tell the difference when looking at the device? I thought that the low RDS(on) transistors had four leads, and the traditional transistors had 3 (with one snipped)?

Example: I am looking at my Asus M4A78lt-M LE, and I see what I believe to be traditional mosfets (only two leads connected), not low RDS(on) devices. The table lists this board as low RDS(on) though ...

There could be some mistakes on the spreadsheet, particularly on the rds and transistor collumns.

We are going off pictures from the manufacturer's website, so somtimes it is hard to tell.

Am I right in saying that I don't think ANY AMD motherboard has a better, higher quality VRM lay out as the CH 4 Extreme?

It's even higher quality then the CH4 Formula..

M4N75TD

8+1 Phase
140w cpu support
Heatsinked
8pin +12

Runs cool with overclocked 955BE, had it at up to 1.45v and the mosfet heatsink is cool to the touch.

No problem - Ijust wanted to make sure I correctly understand how to tell the transistors apart.

As we find updates, how do you want to handle that?

Looking at the design ASUS seems to use primarily only low RDS (on) mosfets and proper drivers consistently on their AM3 boards... I'm not too sure. There can be 1 or 2 drivers I think... I might go back to that article that damric (or who was it) told me about, that's about VRMs. If I could find it.

Very helpful thread! Thanks for all the work guys! Wish i had seen this before i bought mine, but since i got the MSI mobo and 955BE for $169.99 at frys about a year ago, i didn't really research it. I guess i will have to change my avatar soon...when the 'hawks miss the playoffs...

Yeah, Vancouver Canucks don't have to face you guys this time. I'm pretty confident the Canucks'll win the Stanley cup this year, what with Luongo having no losses for game over game on end, all the rookies scoring out of nowhere and Daniel Sedin leading league...... eh, nothing's impossible

Is this it?
