I had a 9 year old system with 256 MB RAM and opening Facebook was quite a challenge for it, let alone running multiple programs. But after being lucky enough to bag (rather rig) this outstanding RAM, now I still have that old system but with new muscles to flex at intimidating sessions like running many applications simultaneously or video rendering. This RAM pumped boiling energy into my machine (without Any other upgrade) bringing the performance index much higher than what it was. And its not any where below 10x more powerful than the old 256 MB black-n-white timed RAM. Thankful to Flipkart for listing this product and the way they delivered it was a breeze. The act of buying it pumped fresh air in my lung as well as my system's. Its been around a month that I'm using this RAM and would suggest the owners of old-old (some time Ancient) system, to inject steel into the backbone of their system by buying this. The journey will be form having a Grey system towards having a Green system. That said, I would also request any prized owner to restrain from cursing them-self after installing this product, even though initially the urge to do so might be tremendous for waking up so late in life. However stability will soon come and you will soon pick up the habit of using an updated and mean system. Always remember that without such a slow system, that you had, your patience would have been far lower than what it is now. Good luck.

did not give my old p4 any significant change in performance not sure.. could be an issue with my old system. anyways, this is an old tech.. no one needs to buy this uneless u need to revive your old p3/p4.. but in case u are planning to do that, i'm telling you. its not worth. latest browsers demand a lot of ram and processing power. so u better buy a new low end system instead. Also, the latest tech, ddr3 is the cheapest ram.
