so adding 1 more memory means the psu cannot cope remember this is a MINI ITX
RIG .mobo draws 10 to 20w including memory cpu 65w max! harddrive(laptop) 5w dvdrom(laptop)5w i will try another psu it is just strange as it is working now for 4days & nights with no issue with just 1 memory
HOW MUCH POWER DOES A DDR2 SODIMM 800 need to RUN? Because it is running ok with no freezing no bsod with 1 memory module. so by you comment adding the second chip then psu cannot handle the second memory module with the 65w cpu combination but the old cpu could. with 2 ddr2 memory i can go into cemos(bios) ,it will post but not load windows. so i have to get a single 4 gb ddr2 sodimm. as a single memory module works fine.pico can provide 150w for a short period.
by my caculation max power drain is 85w for my rig. there is a power simulator for mini-itx mobo's http://www.epiacenter.com/powersim/p...mulator_v2.htm
I used sempron mobile 35watts then added 35watts as my new cpu is 65wats old one was 45 wats
i also used old p4 1.8 which is about 60watts and still cames way under 80watts when playing dvd.surely if power was the issue then when i plug in an external bus supplied usb harddrive (2.5 laptop) which drains more power than a memory stick,the pc should freeze or reboot.but it is fine with just 1 stick!
