I have read one review that this motherboard is memory restrictive. One site says that it only takes unbuffered types.
Went to the ASUS site, and the US portal is down.

I just wanted to know if someone has this type of mobo and i want to know the brands that it supports and why is it restrictive.


More about : asus m4a77d

I just ordered this mobo on Friday, it isn't here yet. You will not find any info on this mobo at the US site. You need to go to ASUS global site. Here is a link to this mobo:

The supported memory list appears to be quite long. I have old DDR2-800 memory I'm going to try on it, specifically OCZ gold 1GB X2 and OCZ platinum 1GB X 2, the platinum is on the list but the gold is not. You don't know until you try, also some people don't realize that sometimes RAM voltages need to be changed in the BIOS. Also, sometimes you need to install just 1 memory module to be able to boot and get into the BIOS to make changes and then install the other sticks.

If you have been looking at this mobo then you have no doubt compared it to the GIGABYTE GA-MA770-UD3. Version 2 of this board has a SB710 and thus supports ACC. Newegg is shipping the rev2 as are most other retailers even though they have not updated the specs.

The GB mobo has an even smaller supported memory list but it has some flash the ASUS doesn't like 2 extra USB ports, 2 extra fan headers, an 8pin CPU power header (ver2) an extra PS2 port and an extra PCI Express x1 slot. But one less PCI Slot, no parallel port and no serial port.

All in all I think the ASUS is a higher quality board and certainly it has a nicer NB heatsink. On the other hand the GB board is a bigger seller and if you google these 2 boards you will find much more info/reviews on the GB board.

my 2 cents

edit: here is a link to the supported memory list at ASUS, it is a zip file

Glad to help! I bought my ASUS from SuperBiiz , it was the cheapest I could find it anywhere after the coupon.

SuperBiiz aka eWiz (tax in CA only)

coupon code:

Also Bing Cashback is 3%

free shipping on both


$81.99 - $11.48 (CUPID14) =
$70.51 - $10 rebate =

if you go through Bing Cashback you will get $2.46 back for a total of


This is version 2, I know because I called and they checked their warehouse and called me back. They have only the rev 2 in stock which is the one with ACC (SB710). Then I picked the ASUS anyway, lol.

$68.79 after coupon
$66.39 after Bing Cashback

Both these boards are a great value. Good luck with your build!
