Windows 7: Windows Will Not Load With 8GB RAM Added

Windows Will Not Load With 8GB RAM Added

My 1st post to this forum in search of a bit of advice.

I have run my PC for 2 years with 2 sticks of standard DDR3 2GB RAM.

My system is Windows 7 64 Bit Home Premium

I recently purchased a stick of Corsair XMS3 8GB and installed.

I removed the original 2 sticks of RAM.

But windows will not start.

Any ideas ?

Regards

Simon

Hello Simon and welcome to Seven Forums.

Without knowing your system specs, I'd guess that your motherboard doesn't support using a single 8GB memory module. Just as an example, let's say a motherboard has four memory slots. The board itself may support 8GB total RAM, but each individual slot may only support a maximum of 2GB. (4 slots x 2GB each = 8GB total memory.)

If you look at the top of any Forum page you'll see a link to "User CP". Click on that and in the left column click on "Edit System Spec". If you fill in your computer details it will help determine what your motherboard can handle. This tutorial can help you find out your system specs.

Looks like the largest DIMMs that are compatible are 4GB.

The maximum RAM is 16GB, but as 4 X 4GB.

Sounds like a plan, Simon. I'm guessing you'll continue to use your original 2 x 2GB sticks and add the new 2 x 4GB sticks for a total of 12GB. You might want to look through your owner's manual to verify which two slots should have the larger memory sticks. Sometimes it makes a difference.

Hi Guys,

Well i got the 8GB stick of RAM replaced for 2 x 4GB sticks of RAM.

Corsair XMS3.

I put both sticks of new DDR3 memory in the number 1 and 2 slots.

We get a bit further this time, windows sign comes up but then, restart and blue screen !

Take one stick out, so back to 4GB RAM and the PC boots up fine.

I'm confused now, any ideas ?

Regards

Simon

Just to make sure I'm understanding things, the computer works fine with the original 2 x 2GB memory sticks. You added the two new sticks (2 x 4GB) plus the original 2 x 2GB and the machine gives the dreaded blue screen. Here's where I get a bit confused: "Take one stick out, so back to 4GB RAM and the PC boots up fine."

Are you saying you did not use the original 2 x 2GB but used just the two new 4GB sticks? If that's the case, try using one of the 4GB sticks at a time and test each slot. Starting with slot 1, put in one 4GB stick, reboot. Does computer work? If yes, shut down computer, and move the same stick to slot 2. Test all four slots. If all four slots work with this 4GB stick, test he second 4GB stick the same way. You may have a bad slot or you may find that one of the new 4GB sticks is bad.

Hi,

Okay i have tried each of the new stick and both work individually.

I then tried one of the new 4GB stick with both of my old 2GB stick = 8GB total and the PC will not start, windows logo comes up, restart and then blue screen.

So i removed 1 stick of the old 2GB = PC now has 6GB RAM and all is well.

I only get start up issues with 8GB RAM.

Puzzling....

Very puzzling to say the least. Are the original 2GB sticks a matched pair? Unless someone else on the Forum can suggest something else to check, you might want to submit an online support ticket to Foxconn and see if they have any answers.
