I have a strage propblem that ive never had with any PC before, I can put the 1 RAM stick that came with the PC in any slot and it works but when i add a extra one or swap out the original it doesnt work, its all exactly the same ram but only the 1 specific ram stick works but in all slots in the PC and the other ram works in my other PC... the exact same PC, so I know all slots work and all stick work but they won't work in this specific PC except the one that came in the PC

@Alex3494 -- it's all exactly the same RAM

 

Absolutely? 

The same capacity?

The same number of chips per side?

The same "speed" specifications?

Some RAM is "ECC" RAM -- having 9 chips (or a multiple of 9 chips) per side, as opposed to "normal" RAM, that has an even-number of chips per side.

Yes everything is the same, same supplier same speed same amount of pins, they work in my other PC which is exactly the same as the one what only accepts the specific RAM stick I've changed the CMOS battery reset the motherboard and update the BIOS nothings working

@Alex3494 -- do BOTH sticks or NEITHER sticks have any chips on the "back"?

 

Do both sticks have the same number of chips on the "front" side?

 

Is one stick labelled "1R8" while the other is labeeled "2R8" ?

@Alex3494 -- see: www.memtest.org

 

to download a program that does "extensive" tests of the RAM.

Create either a bootable USB memory-stick, or "burn" the image onto CD-recordable  media.

Then, with only ONE stick in your computer, boot your computer from the USB or or the CD-R.

 

It probably will take 20 minutes for one "pass" through all the test.

Repeat for the other stick.

The other sticks are fine, they're in my other PC working now
