Windows Experience Index increased from 4.6 to 5.8
Boot-up and Boot-down time also decreased that could be noticed on first boot after upgrade.
Great product. Although I had bought the product at a high price, still I think it was worth paying.

1) I am into iOS development and have a small team of 20 people with iMac's and MacBook Pro's in my office.

2) I have nearly upgraded all my Macs to 10GB+ ram and have never had an issue with this product.

So its a good product tested several times.

I have a dell xps 15 L502X. It came with 4 gb ram and i wanted 8 gb. So I Upgraded it and now performance is significantly faster.
So,now my system specs are-
intel core i7 2nd gen(2.2 ghz-3.1 ghz)
8 gb ddr3 ram(1333 Mhz)
2 gb nvidia geforce gt540m
1 TB hdd..

My laptop is Sony Vaio VPCCB15FG~

My system ratings before (4GB Samsung RAM):
Processor - 6.9
Memory(RAM) - 5.9
Graphics - 5.3
Gaming Graphics - 6.4
Hard Disk - 5.9

And after 4GB RAM upgrade(total 8GB now):
Processor - 6.9
>>Memory(RAM) - 7.4
>>Graphics - 5.7
>>Gaming Graphics - 6.5
Hard Disk - 5.9

Now I can play Battlefield 3(High gfx setting) and Crysis 2(Adv gfx settings) without any laggs..
system bootup time decreased by 10 sec..
sealed product, nice packaging, got it delivered in 5 d...

I having dell lap with 2gb ram. Multitasking performance is too slow with inbuilt ram. now it is upgrade with 4gb + 2gb ram which multitasking ca be performed well. Thanks for the ram. Money worthy product.

Just upgraded the Ram to 8GB (4Gb pre-installed). Couldn't see much performance difference.. may be coz I'm using i7 processor..
bdw, this is the least price I've found browsing through all the sites..

Got delivered in 2 days. Upgraded my VAIO VPCEB24EN to 6GB. RAM works in the upper slot. Just change it in lieu of 1GB hynix DDR3.
Value for money...Enjoying the performance...
Windows Performance Index (RAM) increases to 6.3... Whoa...

Flipkart delivered this product in 2 days. Great job guys.
This product is compatible with iMac mid 2011. My iMac is extremely fast. All applications load very fast. Absolutely no hard disk swap and I hardly see the see the rotating spectrum. Worth upgrading

If you want practically double performance out of your laptop, this is the solution. My i7 HP DV6 wasnt able to handle the amount of heavy applications i used to run on it, I planned to upgrade the laptop and then one of my friends asked me to try increasing the ram from 4gb to 8gb. and yes it worked. i've got a practically new laptop for 1300 bucks! and flipkart delivered in 2 days!
