So my Acer aspire 5750g-9463 is having an issue with new RAM it currently has 2 x 2GB sticks, and i wanted to upgrade, so I used CPU-ID to discover max frequency, which was 1333. So i bought 2 x 4GB for my acer aspire 5750g-9463 http://www.amazon.de/gp/product/B002YUF8ZG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 It's in German because I am currently living in Germany, but I am sure the stats should be easy enough to understand So it came in and i installed it and it doesn't work, it either just power cycles or sometime will stay on but nothing goes on screen, can't even see post or anything. bad ram? some other compatability issue? using only 1 stick in either slot doesn't work i know you're not supposed to mix ram, but i tried 1 old working, and 1 new ram to see what would happen, and it's the same as with new ram, either cycles or it stays on, but you can't see anything, which is the same thing it does without any RAM. I read online that resetting the CMOS battery might help, so i did that, but it still just power cycled. The weird thing was that I put in the old ram afterwards and then it power cycled again. after a brief moment of extreme hysteria, i reseated the old ram and now it seems to be working.... I wanted to try it in another laptop just to be sure, but no one immediately around me has a notebook with a compatible motherboard, so i am left not knowing if there is some other compatibility issue I haven't noticed, or if they just sent me 2 dead sticks? So any other ideas? should i send back the RAM and try to get a replacement? send back the ram and get my money back and by a different brand? what do you guys think?
