I bought two of these for a computer at work. They were fairly easy to install (one in the bottom, one under the keyboard), automatically recognized, and improved performance immediately. Not a lot to say about RAM other than it did what it was supposed to do.

Although delivery was a little slow, installation was easy, price was excellent, and everything worked as advertised. I wish I had purchased it a year ago.

Ordered 2 of these. The packages from PNY are identical but did NOT contain the same RAM!! One looked as on the cover, the other one had merely HALF the amount of chips on each side! This is visible through the transparent package. Still the sticker on the RAM stick said 1GB.

Following my proceedings:

1) inserted both 1GB sticks into my Toshiba Satellite A135-S2386 (after taking the battery out as desired by Toshiba so that both sticks are recognized) --> only 1 GB is being recognized.

2) put the original 512MB stick + the PNY with 8 chips on each side into the A135 --> 1.5 GB = correct

3) put the original 512MB stick + the PNY with 4 chips on each side into the A135 --> 1 GB = NOT correct

This shines a very bad light on PNY!! This is way more than just a different revision, it is a TOTALLY different chip architecture, and the two different sticks s are not even compatible with each other!

Until Amazon has sorted the two different models into two different pages: HANDS OFF THESE PNY RAM STICKS!

in addition:

4) put 2x2GB Kingston DDR2 PC2-5300 from my P100 into the A135 --> 3GB are being recognized (even though the max for the A135 -S2386 is said to be 2GB, but thanks to Kingston. Same "miracle" with a HP Pavilion DV6103, BTW ..)

Summary:
At least for a Toshiba Satellite A135-S2386 and the HP Pavilion DV6103: invest the few extra bucks and get the Kingston KVR667D2S5 here from Amazon, it is obviously downwards compatible to 4200 and gives at least these two Laptops (but probably more) an extra unexpected 1GB beyond the specs.

Upgraded the memory on my laptop. The PNY was a good price and a great performer. Overall system performance increased dramatically over the stock modules.

I'm using two of these memories at the time of wrigint this message.

They work well. My sony vaio has a faster and better perfomance using the new memories.

That's all i can say. Rating: 5 / 5
