ASUS P8Z77-M - Motherboard doesn't run with more than 2 RAM sticks.

[hellhound_]

Sorry if this is a stupid question, I'm not exactly computer savvy so I apologize in advance.
Recently I bought two new RAM sticks and they didn't seem to work when I add them to my motherboard (ASUS P8Z77-M), I updated the BIOS with the most recent version and all it did was allowing two different sticks to work together, so at least I know they are compatible.

My RAM sticks are 2x Corsair Vengeance LP and 2x Kingston 10600 Cl9 240.

Here are my specs:


Processor
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz

Video Card
AMD Radeon HD 6700 Series

RAM
8.0 GB

Operating System
Microsoft Windows 10 (build 14393), 64-bit

BIOS
BIOS Date: 12/15/15 16:37:02 Ver: 22.03
Version
American Megatrends Inc. 2203
Manufacturer
American Megatrends Inc.
Date
12/15/15


Can anybody help? Thank you in advance!

Try testing with single RAM each slot. See if all of them do work.

Are the sticks 8GB or under? Since the mobo only supports up to 32 GB

Mixing multiple kits together can cause a PC to be unable to boot or unable to operate at rated specifications. Such combinations carry no guarantee to work together by memory manufacturers.

A work around may be lowering the memory clock to a slower speed to get them to work.

Hi, thanks for answering. I just tested it and the third and fourth slots don't work. The PC keeps rebooting and a red light turns on the motherboard.

Hi, thanks for answering. All of them are 4GB.

Hi, thanks for answering. It's weird because the computer works if I put on one of each, it didn't do that before I updated the BIOS, but now it does, maybe they are compatible?

It might be a bent pin in the CPU socket. Try removing the CPU and check the socket. You can post a picture of it here.

No problem, the resolution is not very good, but I think that there is a bent pin on the first row under the circuits in the middle of the socket. If it is, try straightening it and check for others.

I didn't see anything bent (not that I'm doubting your expertise) so I took some more pictures with an actual camera. http://imgur.com/a/TafJR

It looks to me like one pin is missing and one is slightly bent (the one under the missing pin).
But I might be wrong. Try a closer look with a magnifying glass and comparing it with:

Here a closer look:

It looks like someone tried already to straighten several pins (on the left of the missing pin).
Is it a new board, or you've bought an used one?

It's quite an old board, I think I bought it in 2012 or 2013, can't remember.
Now that I took a good look it does seem like there are some bent pins, and others that are alright missing. I'm not gonna try to straight the bent ones because I don't want to fuck things up. Is there any possibility of the problem being something else?

No.
