Hi all,

I recently decided to beef up my system by purchasing some new Corsair Vengeance 2x8 GB DDR3 1600MHz for my aging computer. I looked around and found that my motherboard, the Asus M4A77TD, should be compatible with up to 16GB of DDR3 1600, so I figured I would buy this ram. Unfortunately I cannot get the computer to post (not even a beep) with even 1 stick of the new ram installed.

Looking through the manual I came across, in small type, a warning saying that the motherboard only supports up to 4GB DIMMS (which is not mentioned anywhere on the box or tech spec sheet). I just want to make sure, before trying to send the ram back to amazon, that there is absolutely no way that I can use this ram in my system?

Thanks in advance!
 
I would think that you would most likely have to return the 8GM DIMMs.

The only other option to try before returning the sticks is to go over to the ASUS website and see if they have a newer BIOS for your motherboard. It is possible that they may have unlocked the motherboard's ability to use 8GB DIMMs.

Good luck.
 
I used to have this board, and when I upgraded the memory I had to sort of introduce the new sticks one at a time, with the old memory still on the board, else it wouldn't boot. I wasn't using 8Gb sticks, but thought this may be worth a try?
 
Thanks for the advice everyone. I flashed the BIOS to the latest version and tried again, inserting the sticks one at a time between resets, now seems to be working. Both Windows and CPU-Z are reporting 16GB of RAM.
