I m looking for to upgrade my notebook acer aspire one with a ram 2gb corsaire,kingston or what else?
Choose anything which offer great features. Make sure to buy RAM which is compatible with your Notebook (DDR and PC Type also the maximum allowed memory for each slot). Timing and Latency is very important to choose high quality RAM. RAM which uses (passive) cooler is recommended.
In Brand of RAM i mostly prefer Kingston. Its mostly high in its technology and and also in its reliability.
kingston was ok years ago and still high up there, but with new ddr 3, ddr 2 ect i have learnt from some fello pc builders that Corsair has the edge now. it also goes on the rating is it for a pc, or gaming pc
Nowadays the top 3 are Corsair, G SKill and Kingston Check out Unboxing and review of my amazing Corsair DOminator Platinum 8GB 2133Mhz kit
Brand is not important. Buy for the best price with these guidelines: Always buy RAM that carries a manufacturer's lifetime warranty. Always buy from a reputable vendor with attractive return policy. Always buy RAM with the specs set forth for your Mac model. Two reliable vendors are OWC and DATAMem.
Choose anyone with noting following points - Make sure, it have same frequency speed to match with your previous laptop ram (so it will fully compatible) - Have more repair/replacement warranty - Good fast responsive support - Service center near to you
The vendor doesn't make a lot of difference. The speed and latency is what matters the most. Corsair, Crucial, Kingston etc. are all pretty decent vendors.
