I'm being told that my memory does have SPD. So I'm still confused. I'm not sure what the problem is.
Check the spec of your memory and compare it with the requirement given in the given link. Take notice of the note box. You need to remove your pci card.
You will also find a list of ram that are compatible with the board.
I checked the specs, my memory seems to match except the SPD issue and this: "Double-sided DIMMs with x16 organization are not supported".
Of course the SPD thing has been settled. I've read that the "x16" issue frequently can't be determined simply by the stick's physical appearance (but mine is double-sided physically and has 8 black modules on each side). I've posted again on the memory manufacturer's forum to get an answer on that.
Take a look at the link. It has 8 devices in the front and 8 devices also in the back. This is the spec of one of the memory ram supported for your board. http://datasheetz.com/data/Memory%20Cards,%20Modules/Modules/MT16HTF12864AY-667D4-datasheetz.html
I'm not sure if your ram is rated 1.8 or 1.9 V. But I'll assume that you have check this out. Usually to match the ram with the bios manually you go to the performance menu and change the frequency multiplier to produce the frequency rating of your ram. Then you change the first 4 latency values based on the ram specification. For example if your ram has a latency rating of 7-7-7-24 then change the bios latency values to 7 - 7 - 7 - 24. The voltage sometimes needs to be change from a default value of 1.5 to 1.8 or 1.9V (not sure if this is possible for your board).
Well, that's basically what I was saying, that the physical appearance alone is not necessarily a valid indicator. 8front/8back may not mean "x16", or does it?
My question is, if the memory is "x16", what will the board's response be on boot? An LED light and nothing else(which is what I'm getting)? or error beeps ? fans & a boot? I don't know.
Have you tried setting the latency and voltage values in the bios with those given for your ram?
If yes and you still have that problem you could be right in deciding to change those ram with the correct ones.
