Specs: Windows 7, intel celeron
I tried to upgrade my hp 620 running on windows 7 ultimate 64 bit by adding a 2 gig RAM DDR3 and it failed to switch on. it was in an empty slot, it's already running on a 2 gig and the processor is 2,10 GHz Intel celeron duo core. i still want to upgrade it with at least a 4 gig and i was asking will it work?

✔ Best Answer
Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibility your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:

Once you know which module ID strings (part numbers) work in your mboard, you can get them from anywhere you like that has ram with those ID strings.

If you have brand name ram, it is usually easy to look up whether it's ID string (part number) is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.\

If this is your notebook:

It's a HP Business notebook - you may need to select that when you looking for compatibe ram
