2x4gb ram only giving 4gb

Maxime Trepanier · Sep 1, 2015

Hey there. so I bought a 2x4 gb Ram AMD Performance DDR and its only showing 4gb working. I have to put another 4gb ram to get 8gb ram but I should be getting 12gb no? I tried searching for answers but nothing to help my problem. is there any way to unlock? thank you for any help u can provide me!!

what operating system are you using? is it 32 bit or 64 bit?

EDIT: never mind, I misread your post. you are showing 8 when you should be getting 12. swap the sticks around to see if you have a bad stick,

Ok i'll try switching the ram, is it possible to get 12gb installed and working? I remember someone telling me that you could only have either 4GB-8GB or 16GB and that 8gb + 4gb isnt possible

take all the sticks out except one. then boot. shut down and take that stick out and try another. do this one at a time to see if each stick registers.

Maxime Trepanier :

The total RAM is only limited by the top end. Most mobo and processors have groups of 2 or 4, though sometimes 3. You just get a speed boost from using the groups, but you should be able to use whatever slots and however many slots you have up to your max. The mobo manual should also cover how to use, where to put, and how many RAM DIMMs to use.

I did that already I put my 2x4 gb and got 4gb ram I removed my 2x4 gb and put my only 4gb stick and I got 4gb. It's like my 2x4gb is only giving half of what it got, like it was locked somehow.

I have put my RAM like they say in my mobo manual which is first stick in DIMM_A2 and 2nd stick in DIMM_B2 then extra sticks in DIMM_A1 and DIMM_B2...

Nobody know how to fix that ram? why my 2x4 gb is only giving me 1x4? ^^

Maxime Trepanier · Sep 1, 2015

Wow it must be one hell of a problem I got then if nobody in tom's hardware can answer me!!

Sorry out of my realm of knowledge.

Hi

Did you put the 4 GB ram modules in one at a time ?

This will show if you got. 2 x 2 GB modules or a dead 4 GB module or 4 GB modules which are in compatible with the motherboards chipset ?

I have put my 2x4 gb stick alone in the DIMM_A2 and it was only showing 4gb installed. I removed this one and inserted my 4gb stick and got 4gb... I dont know what else to try but I remember reading somewhere that you could unlock the ram. I remember trying it on my old system but it never worked, I tried looking on google to try it again but I cant find where to do it on windows 10.. I guess i'll just let it at 8gb

Hi

I is strange you have a single memory stick described as a 2 x 4 GB stick of DDR ram

I would expect a single stick to be described as a 4 GB stick
Or a 8 GB KIT consisting of 2 x 4 GB sticks of ram

Is this a old computer using DDR ram ?
Or DDR-3 which is used by most recent PC's
Or DDR-4 or DDR-2 ?

Ddr3 and its a AMD PERFORMANCE stick that says 8GB(2x4GB)

mbarnes86 · Sep 1, 2015

Hi

Is that marking on the packaging or on a label on the stick of memory ?
I would expect a 8 GB kit to contain two 4gb memory sticks each marked as 4 GB

May be you got half a 8 GB memory kit.?

Sounds like a bad stick. if you are putting an 8GB stick in and its only reading 4 then I cant think what else it would be except a defect in the chip. I would return it right away for a replacement. most places will let you exchange a defective item even if they dont allow returns on that item.

Maxime Trepanier :

Can you take a picture of the stick of RAM in question and show us? Perhaps we just don't get it, but I've never heard (or read) of a single stick that was labeled as 8(2x4).

Maxime Trepanier · Sep 1, 2015

Hmm, well after looking for images on google It clearly says on the ram 8GB(2x4GB) but it also says that it comes in pair of 2, but I bought a PC off ebay 2 years ago and the ram was already in the PC. there was only one in the PC. perhaps I dont have a problem at all lol!! My bad!!

That is what I thought might have been the case.

Sorry to hear that it only had one stick of 4GB RAM to begin with.
