Hello , I'm buyed a new desktop computer with 4gb 1333mhz ram memory ( DDR3 ) and i want to upgrade my system to 8gbs but in the shop i have only find 4 gb 1066mhz ram.... Can i combine 1333mhz + 1333mhz ( 'couse i have 2 of 2gbs ) and 1066mhz... Is it safe? couse my computer is new and i dont want to made any crash. This is my spec:

CPU: AMD Athlon II X2 250 ( 3.0ghz )
Ram: 4gb ( for the moment )
Motherboard: Biostar NF520D3
GPU: EVGA GT 430
OS: Windows 7 Ultimante 64bit

maybe ... But i realy dont know is my computer good for itt... couse i have 3.0ghz CPU , is that compatible?

Compatibility has to do with the PCI-e lanes on your computer and not your processor. For example, if you only have PCI-e 1.0 and are limited to x8, you will get a performance bottleneck because of insufficient bandwidth. If, however, you have a PCI-e 2.0 or 3.0 compatible motherboard and a lane which can run at x16 you should be perfectly fine.

Edit: looked at the spec sheet for your motherboard, and you shouldn't have any issue with PCI-e compatibility. You may still have an issue with how much power the card will consume and whether or not your PSU can handle it.

Since you just got the computer it may have a good psu but it would be helpfull to list it for us. The cpu is good speed at 3.0 ghz so tou shouldn'e have an issue with any of those cards.

[strike]Another question for you -- what version of windows are you using ?? (32 bit or 64 bit ??) - If you have a 32 bit version of windoews adding more than 4gb. of ram will be a waste since 32 bit versions can only use a total of 4gb of memory so the rest would be unused unless you change to the 64 bit version ![/strike]

EDIT : Just reread and noticed it listed 64 bit !
