Boot failures after upgrade of ram

Recommended Posts

Hi,

I had a set of two corsair rams (cmx4gx3m2a1600c8) and wanted to upgrade. I bought another two sticks (cmx8gx3m2a1600c9) because there weren't any c8 with 8gb capacity.

My system doesn't boot at first. Then I switch it off , power again, and then it boots normally.

I ran memtest to every single ram and see no errors. Then I ran memtest by pairs and it gives me 2,3 or 4 errors with the new sticks and only when they work in dual mode(never alone).

Do you think I shall give them back and ask for new same pair, ask them for something more compatible (in case I was wrong at first) or do something else in the bios?

Thank you in advance.

By the looks of it your board doesn't supports 8gb modules. Specs say maximum 4x1.5v modules totalling 16gb of ram. Meaning 4x4gb sticks. I'd return the modules and get a totally matching 4x4gb kit. Checked the memory support list for your board. There is no 8gb modules listed at all.

 

edit: my bad I didn't look up the exact kit. Sounded like you were trying to use a 2x8gb kit. R u running the kit by itself or running it along with the other kit ? Mixing the kits is a bad idea. Also are you using slots 2 and 4. Is xmp enabled ?

I m running it by itself and combined also.

I m using all slots or 1&3(if alone)

The xmp is off. When I turn it on, the motherboard beaps and then it boots under safe defaults.

 

I believe that the kit is bad, because they always give errors in memtest. Is there anything else that could cause the problem.

 

I know that the motherboad sets at 1333 MHz , the i5 and the rams are 1600, but that was compatible from the beginning and the technician-salesman advised me so.

with xmp enabled it works at 1,65v. i did some more tests today (if there was something wrong with the slots) and then i was confident that the ram was bad. i gave them back, they tested them and gave me a new pair of the same modules.

thank you for your comments.
