So I have gigabyte ga-ep41-udl3 motherboard and it supports up to 8gb of ddr2 ram max 1066 mhz..And I had 4 gbs 2x2 2gb ddr2 800mhz..Now I got 1 more stick of 2 gb ddr2 800 mhz and when I put it in it doesn't work I mean my pc runs but black screen or it starts beeping.So I knew prb is ram then I tried removing ram in diffrent slots and then it works monitor is on but after first picture displayed my pc keep restarting...Then I tried just the new ram solo and it works so I knew it's not new ram...So my only thought about this is that my motherboard can't handle more ram?Which is pissing me off I mean if it says up to 8gb even 1066mhz speed and my can't even handle 800mhz...I even tried to rr cmos to put it off on couple minutes but nothing....I have alot of ram by 1x1 gb ddr2 800mhz and ofc doesn't work if I put more than 4gb into my pc....If you came to this part of text thank you for reading all of this pitty text...Help
