Question: toshiba nb505 Is this the right one for a toshiba nb505???
Document: So I recently bought a new notebook (Toshiba mini, nb505) that has Windows starter. Looking at the specs, I thought it would be fine right out of the box. Oh boy, was I wrong. I didn't realize how "bloated" this "basic" OS would be. I'm used to XP, and my last netbook (ASUS something) which recently died just flew on 1GB RAM.
This is not the right (2G) memory for Toshiba Netbook NB305-440. According to Crucial's website the 2G memory upgrade for Toshiba's netbook is CT1290394. I can't find it on Amazon so I'm going to buy it directly from Crucial. Amazon was nice and took back the wrong/recommended one I had bought.
I purchased this memory to upgrade my Toshiba nb505 netbook. I had never done work like this to a computer of any kind before. After finding a how-to youtube video, I replaced the memory in less than 10 minutes, no problems whatsoever. The netbook is working perfectly. As others have stated, be sure you know if you're replacing a D2 or D3, which is printed on the sticker on the bottom of the netbook.
i wish i looked around before i ordered this, opened the package, and tried installing it... but alas, it doesn't fit.AGAIN, this is not the right part for a Toshiba nb255-n245.
It fits my Toshiba NB505-N508BL perfectly! Just popped right in. This little tip helped me. I did not write the follow, it is from another review and it helped me to decide which RAM to buy for my Toshiba:"NOTE: Two types of DDR memory are used in the Toshiba NB500 and NB505 netbook series.
This made the use of my Toshiba Netbook much much much better. From lag to no lag in as little as the two minutes it took me to install it. Thanks for a great and easy to install product that fits right in there and immediately ups the performance of a netbook, especially when using multiple applications or web sites.
They should have made it clear. To find out if your Toshiba NB505 uses DDR2 or DDR3 just look underneath your netbook for the big white sticker that has the part number and serial number. In the top right corner of that sticker it should say D2 or D3. D2 obviously means DDR2 and D3 obviously means DDR3.Anyways, my computer is running wonderfully now that I've upgraded to 2GB RAM, plus it was a very affordable price! $13! Awesome.
Works perfectly in my Toshiba NB505 netbook with window 7 starter no upgrade software needed just took out my one gig and stuck in the new two gig and I was ready to go the speed was instantly noticed.
This item comes up in Amazon search as being the correct upgrade for the Toshibe Netbooks NB500/NB505 series computers. IT DOES NOT FIT INTO NB500 Series!!! It is a 204 pin memory. TOshiba netbooks use 200 pin. Amazon has the correct Crucail brand 200 pin memory also, but it is twice the price of this one, so most people would choose the less expensive, but the will regret it.Amazon needs to change their description and search results to warn people about this.
While Amazon recommends it and some people have got the right chip to make it work, this is not a good buy when come to adding memory to your Asus 1015PN. I have read that it needs to be a memory chip with 8 chips on it and Amazon tends to send the one with 16 chips on it and this may or may not work with your computer.
Answer: I just bought my NB505. Look at the black and white sticker on the back of the computer - it says Toshiba. On the upper-right corner it will say D3 if it's the D3 that will fit this memory module. I ended up ordering my module directly from Crucial because I wanted to make sure I got the right one.
