hp a636n RAM?

Question

Here are the memory specs of the computer- http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00223147&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN#N299

I plan on buying a Kingston HyperX 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200)

Will the hyperx set of ram work well with the 2x256MB thats already installed in the computer? Or will it not work at its maximum performance?

the motherboard has 4 slots for ram... 2 have already been taken by the 2x256. Theres 2 open slots left, and im thinking of adding the hyperx ram and im wondering if these 2 different sets of ram will work together well or will one slow the other down.

Answer 1

Your Hyper X may have better timings than the ones you have now. If you mix those modules, dual channel mode (which is fast) might be disabled. But all those four will definitely work under single channel mode. Not all programs require the wide bandwidth of dual channel mode.

Answer 2

The most likely scenario is that you will have to remove BOTH of the modules in your PC and replace them with the new ones. Most PCs have no more than 2 sockets for memory

Answer 3

nope..it's not gonan work well with ur comp...cause all new pc u need 2 hav same brand, same speed same series and same pin ram 2 achive a maximum performance
eg if you hav a 333 MHZ 256 x2 on ur comp..u need 2 buy the exact same speed...333 MHZ and 256 x2....and the same brand
in ur case i would suggest replace the whole thing (Y) upgrade ur comp like 4x512 MB 184 pin DDRSDRAM 400MHZ ...! yeh

hope this help !!!
cheers !

Answer 4

sounds like a dell computer 4 slots i don't think it will work together the ram will all have to be the same but im not positive of this good luck

Answer 5

actually it will run slower than the kingston ram because it will have to access data from both sets, thus increasing latency. if you had 4 sticks of that kingston, it will be slower as well.
