Question: I have Sony Vaio laptop (Model : VPCSB18GA). It has 4GB RAM. I want to upgrade it to 8GB. Can I use this RAM to upgrade my Sony Vaio laptop.
Document: Seems to work great with my 2010 Sony Vaio F series core i7 laptop. Replaced the factory 4GB with these 8GB. I was concerned about the Windows Experience Index scores being equal to the factory's, but after updating the WEI, the RAM gets a score of 7.4 just as the factory RAM had.
I just added these DDR3 RAM chips to my Sony Vaio with the Intel I-3 and I couldn't be more delighted. While Windows 7 might work with just 2GB of RAM and 4GB appears to be the norm, 8GB is well worth the upgrade. Best value I found, these worked right off the bat and now my nice little 4 1/2 pound notebook is running even faster than before. I'll be back for more, now I just hope my wife won't kill me when see sees my latest indulgence?
I rarely make product reviews, but I feel the need to share my experience and satisfaction with this particular product. I recently upgraded my Sony Vaio E-series (VPCEH) laptop memory from 4GB to 8GB, and I must say the improvement was noticeable; it runs quicker and smoother. The installation was quick and easy, no worries whatsoever.
I just purchased a new 2011 base model Mac Mini with 2GB of memory. Instead of paying Apple the $300 they want to upgrade the memory to 8GB I searched Amazon and found this option for one fifth the price. I'm not a "tech guy" but removing the two 1GB cards that came installed in the Mac and replacing them with these two 4GB was easily completed in less than five minutes. Everything is running smoothly with no problems to date.
fast,very easy to install in my Sony Vaio laptop. had it for 2 months, use it daily without a hitch. worth the $$$$$.
I purchased this to complement the 4GB already available on my Sony S Vaio laptop. Installed, restarted and works like a charm! It was shipped pretty quickly as well and arrived sealed in the case. Word to the wise, it may prove a bit tricky to extract it from the plastic once you get it open. Take your time and gently pop it out.
Bought this kit for a 2 year old Sony Vaio E series laptop. Installation was easy but then my problems began. Let me say at the start, I'm no computer geek and I'm not a gamer. Just wanted my laptop to run faster. I had read that a ram upgrade was the quickest and easiest way to do just that. Bought these and yes, it did make my laptop faster to begin with. BUT, It started shutting itself off and restarting without warning.
I work in IT for a company that uses mostly Macs. Some users use Parallels to run Windows 7 within Snow Leopard or Lion. Then there are the PhotoShop users. Either way, they need more than the stock 4GB of RAM and this is the best of the best!. Just make sure to double check your model to ensure you are buying compatible parts for your model laptop.
I have the newest model late 2011 macbook pro. i7. I use it mostly for video editing. It is absolutely not my favorite laptop and very slow for rendering on 4 gb ram so I upgraded the RAM. i bought these then about mac shows that the ram works on 8 GB, 1333 Mhz, DDR3, so I thought everything works great. However, adobe after effects renders slower. It was 55% use on 4GB RAM and about 45 minutes to render this video i made.
I find it very difficult to rate anything as perfect but this is a great upgrade. I recently purchased a Sony S laptop with all the bells and whistles. I didn't want to pay "The Man" for their overpriced upgrades so I researched beforehand and found this item. I consider myself tech savvy but I still take a deep breathe every time I open one of my PC's or Mac's. This went off without a hitch and was recognized immediately. I ran the tests and there wasn't an issue.
Answer: yes. according to your laptop specs it should work fine
