I have an Aspire5733-6650 that came stock with one 2 GB stick of DDR3-10666. I replaced it with one 4GB stick of PNY DDR3-10666 from Best Buy. I dont know what the timings are as laptop BIOSes almost never give the user the ability to change or view that info.

Anyway, when I turn the computer on with the 4GB stick it just randomly tuns off, usually within 45 seconds. I was able to boot into Windows once and Windows did regonize that 4GB was in the computer, so it sees all the RAM. I tried both DIMM slots, and I exchanged the RAM for a new stick. The 2 GB OEM stick works fine, the 4GB one wont. Google says the computer supports up to 8GB sticks.

CPU: Core Two Duo 2.13 GHz. E6400 OC'ed to 3.0 GHz. / 380 FSB RAM: 2 GB. Corsair 800 MHz. XMS2 DDR2
GPU: X1900XT 512MB Connect3D Mobo: Gigabyte GA-965P-DS3
PSU: 535 watt Enermax Whisper II HD: (2) 320 GB. Seagate Barracuda 16 MB. 7,200 RPM SATA II
OD: 52X DVD±RW Monitors: (2) Hanns-G JW199D 19" 16:10 widescreen DVI in extended desktop mode

it just randomly tuns off

Do you mean that is totally shuts down as in no monitor, fans shut down, dead? Or does it freeze or blue screen with fans (including power supply fan) still running?

Have you tried exchanging the 4 gig stick for another 2 gig and use two sticks of 2 gigs instead of a single stick of 4 gigs?

Also: Try booting from "live media" such as a Linux distro, rescue disk, Windows installer or similar (on CD/DVD, flash drive, SD card etc.) with the 4gig stick to eliminate the possibility of it being a hardware issue. 

Will it boot to safe mode with 4gig stick?

The laptop supports 8 GB max RAM in 2 slots which means a max of 4 GB sticks. It's possible the RAM you purchased isn't compatible with your laptop. Can you give the specifics on the RAM you bought? Thanks.
