What's the default voltage of the DIMMs?

1.50v

No the Mobo does not see it but CPU-z sees 32GBs

This is from your motherboard's manual, which is available on the ASUS site if you didn't know.



Not saying that this is the problem, but...worth a try.

I'll try but what if my Rig won't turn on?

You should be able to check without powering down. Just take a peek next to either end of the DIMM slots to see if you can read something to signal which slot your RAM is in. You should see something like A1, B1, C1 etc.

You may not be able to if you have a large cooler. The DIMM identifiers are on the CPU side of both slot banks. Circled in red.



As long as you're absolutely sure you have Windows 7 Ultimate 64 bit, the RAM is in the correct slots, you didn't disable anything to do with RAM in the BIOS and you have tried different RAM slots like you said in your initial post....I would do a BIOS update to revision 0701. If it doesn't change anything we'll go from there.

I took a look and I wanked up the spots.

Well everyone thanks for help sorry that I'am just plan dumb.

Power that sucker down, turn off the PSU by the switch on the back, touch the case to equal out static electricity and swap the RAM into the correct slots for your four DIMMs. Boot into BIOS to see if it recognizes all four DIMMs and then boot into Windows and report back.

If your motherboard can't see.... how would CPU-Z see it? wink.gif

Its goes something like: CPU-Z => API => OS => API => motherboard

What CPU and CPU cooler do you have? Double check installation and make sure no CPU pins are altered. Also, too tight of CPU cooler can cause a similar issue, so these are things to check.
