So i have an Acer aspire laptop running windows 7 64 bit with 2 GB RAM. I want to upgrade RAM so I used newegg to determine that I should upgrade it to 8 GB ddr3 1333 PC3 10600 (4gb x 2 sticks).

I installed it, and upon firing it up, everything boots ok except that now the screen resolution is reduced and cannot be adjusted in display settings. Further, the machine is now waaay slower than it was with the original 2 GB ram. What gives? This is a matched pair of ram sticks, supposedly brand new and tested.

When i enter my system info on another ram upgrade site, it tells me to use ddr3 PC3 8500. Would this rating difference account for the problems I have with the 10600 ram? Can anyone straighten me out before I send this memory back?

Help please!

Yeah, I'd read the old RAM sticker IF ACER HADN'T COVERED IT WITH A BARCODE STICKER WHICH TOTALLY MUCKED UP THE ORIGINAL STICKER AND MADE IT IMPOSSIBLE TO READ. THANKS ACER!!
