Ram

That machine uses dual channel.
That means each matched set/pair of ram must go in the proper slots......review the manual.
If you mix the sets/pairs/slots odd things might happen.

Work with the bios.
Get it to show all that ram proper.
With a little luck it might also show single or dual channel mode.

ok here goes i can use either set or one of each as long as only 2 slots are full it only shows 2 gigs of memory I went to the crucial site and the download show only one module installed at 2048 gigs of memory motherboard specs say it will support up to 8 gigs

I gave my opinion of ........work with the bios.......to try and get this sorted.
If you can't get the bios to see the ram proper......your dead.

You seem to want to work with windows.......good luck.

In reply to: Well

after more testing memory I have come to the conclusion that I have a bad mem slot if I move either of the sets to the other 2 slots it reads I can put 1 in the second of the 2 slots and it shows 6g if I fill all 4 slots it will not boot or if I fill the first of the other 2 same thing out of warranty so I guess I will just have to live with it next time I will build my own again seem to have better luck that way thanks for all the help everyone

That might be it or it might still be ...

as Bob suggested and I hinted at.

You have 4 slots, two of one color and two of another color (blue and black are common). Instead of putting both of the original DIMMS in side by side slots of the same color try putting one in slot 1 and the other in slot 3 with new Kingston is slots 2 and 4

Then you'll need to contact Acer

Then you'll need to contact Acer to first find out if your particular model system will support the total amount of RAM you want to install, and if so, to work with them to find out if this is some sort of warranty claim issue.

It's also possible the RAM you purchased is DOA, so try testing the new sticks individually to see if you can isolate a bad one. It is possible for both to be bad, but that would be an extremely rare occurrence, and would more than likely mean that you introduced ESD damage to them.
