Problem with new memory when using both sticks, fine with one.

Junaid_5 · Sep 28, 2016

I bought some memory (listed below) for my motherboard, Intel DQ67SW running an I5 2400 3.1ghz.

APACER 8GB(2X4GB)DDR3 RAM MEMORY PC3-10600 1333MHZ 240-PIN CL9- P/N 75B83C1G120B

I have updated to the latest bios.

I use Dim slots 2 and 4, the blue ones (as stated by the manual), with a 2GB ram stick in each, everything is fine.

If I add one 4GB stick to dim slot 2, its fine, runs with 4GB ram, if I add the second to dim slot 4, my pc doesn't load, fans work, screen stays black. Both ram sticks work when alone, they just don't work together. Im not sure what this problem is, but I don't think it is compatibility as the ram sticks do work when alone.

Any help?

I want to get one last opinion before I return the ram sticks just in case someone knows how to fix it.

Is your ram on the supported list for your motherboard?
Apacer will have an app that lets you check.
Sometimes, older motherboards has issues with the way ram was constructed.

Its not on the list, but why does the PC work when only one of them is installed? Doesn't that mean it is compatible?

if you put the 2 gig in blue channel and use the 4 gig in grey one does the system post .

You could contact Apacer support.
But, I think it would not be worth the time and hassle.
I would return the ram and find a kit that is supported.

Check your mainboard specifications and how memory should be installed. That mainboard says it supports double-sided -OR- Single-sided memory. It may not support them together. Some mainboards are like this. Check your memory sticks and see if one has chips on both sides (double-sided) and the other has chips on only one side (single-sided). You can try one stick in Blue and one in Black and see if it works. SOme mainboards even require specific placement when insterting mixed memory. Single sided-only in A1,A2 or only 1 double-sided mixed with single-sided if installed in B2. etc.

Pull the DRAM, reset the CMOS, install 1 stick in slot 2, go into BIOS and set DRAM voltage to + 0.05 over spec, save, exit, shutdown and add stick #2 in slot 4.

Doing all 4 sticks have my pc io1 initialisation error and now it doesn't work with just the old ram too.

Try 1 stick of old and move it to each slot until it works. what changes to settings did you do before using all sticks at once?
