1/2 the ram showing up in system info

say, this pc isn't even hooked up to the internet at the moment. i can only relay what info you're after. sorry

Fair enough.

And yet you have access to the internet from some other machine, to post here. Can you download CPU-Z using this machine, and then install it on the other machine, and run it as suggested?

If you only show 4GB out of the 8GB, the SPD tab from CPU-Z will show you each of the slots you have memory sticks installed in, and will show whether there is or is not any memory in that slot. This would be very revealing for diagnosis.

I know you have physically installed a 4GB stick in each of two slots, but we need to see what the hardware thinks is actually present in each slot, and that's exactly what the SPD tab shows from CPU-Z.

I wonder if the two sticks need to be installed in slots #1 and #3, rather than #1 and #2?

Let me clarify this. You say that you have 4 x 2GB sticks of RAM installed, making 8GB, but the BIOS is only detecting ½ that amount, i.e. 4GB. Correct? What is the full part number of the RAM modules?

no...2 x 4GB
0n the package...
F3-12800CL9D-8GBXL
DDR3-1600 PC3-12800
4096 x 2
CL9-9-924 1.5v

I edited my 1st post as is confusing and I am sorry. 2 sticks...totaling 8 gig. i'll download program, xfer it to new pc. hold on

the book reads...
"you may install varying memory sized in Cahnnel A and B. The system maps the total size of the lower-sized channel for the dual-channel configuration. ANy excess memory from the higher-sized channel in then mapped for single-channel operation."
also...
"We recommend that you install the momory modules from the blue slots for better overclocking capability"

Blue slots are listed as Dimm A1 Dimm B1, and black slots as Dimm A2 dimm B2

Currently installed into blue A1 & B1

Thanks for the clarification. What do you get when you have a single stick installed? Try both sticks individually. It could be that one is bad.

i think i'll try this 1st. thx for jogging my brain

CPU-Z will provide the definitive answers to all the mysteries.

The MEMORY and SPD tabs will give specific answers to what is currently speculation.

Looking forward to the results.

slot 1 dead. used the recommended program at the end to verify. initially stuck one stick in slot 1, alone and pc would not boot. great...i stuck in slots 2 and 4 and all the ram shows up. guess i get to return mobo to newegg. good grief
