Must the second DIMM go into slot #2 ?
I had a PC where the second DIMM went into slot #3.
Don't ask me why.

bigboi972 let me see if I understand you correctly.

Both new ram modules work in one of the motherboard slots.
Neither new ram modules work in the other motherboard modules.
When installing both ram modules the system only shows one.

If this is true and the bios are set to default in my opinion your motherboard has a bad ram slot.

Check what version of BIOS you have on the CPU-Z Mainboard tab.

Version 1.40 description shows a "Memory Patch":
Quote:
1. Improve system compatibility.
2. Patch Crucial DDR3-4G-1600 and APACER DDR3-1G-1333 memory.
3. BIOS [Case open] option default set to disabled.
4. Improve Windows compatibility.

Good find David. That information should shine some light.

@bigboi972
Because I know you are going to keep your motherboard manual as long as you have that motherboard. A little one of my rules of the thumb.
Always write down the bios # down inside the front cover of the manual and the # of all bios you have used on that system. Just might come in handy.

Correct, you won't hear the beep codes unless you connect that little speaker.
Is it easy to get to now so you can install it?
