This is the RAM you need to update your Advent 4211 to 2GB RAM and it is so cheap!

Installing the RAM is very easy too. Just turn your notebook upside down, take out the battery and unscrew all the screws you see in the bottom of the case. Carefully lift off the case bottom (especially around the ports on either side) and you will see the RAM slot above some black tape (this holds the installed RAM). Slide the new RAM in at roughly 45 degrees until the clips either side click above it. If it does not fit in all the way adjust the angle until it does or it won't get recognised once you switch your Advent back on. There is a gap in the base of the RAM so there is only one way it will go in. Once you have done that put the bottom back on and the battery back in and that is that. A very cheap upgrade.

This RAM is also what you need to upgrade the MacBook. You get to the RAM compartment underneath the battery and there are a couple of screws to remove. See the Mac site for details on this. If you have two 512 RAM peices, you will need to buy two of the above to get 2GB. All very easy and one upgrade you should ALWAYS do!

i got this for my advent 4211 (msi wind) works great so now running 2gb.... great item

I am 100% happy with this RAM and it is in the computer I am using now (Apple MacBook) Amazing price too thanks Play.com!!!

took me five minutes to fit. my pc runs much faster and switches between and opens applications much faster. easy way to make your pc much faster

Got the ram this morning and got it fitted in 5 mins, great job, well recomended!!!!

If you have anything less than 2Gb of RAM in your laptop, you simply MUST buy two of these and upgrade. This is the cheapest RAM I've ever seen, and it's just astounding. I recieved mine in the post today, and after replacing my current 1Gb in my HP Pavillion zd8333ea, there was a huge difference in performance, even in an already well-performing laptop. Music plays instantaneously at the click, programs and games start up much faster, and now I can minimise and restore games with hardly any lag.
That said, of course there is much better RAM out there, but for much more monies£££. You can get the seriously high quality, hardcore gamer RAM used with overclocked rigs, but be prepared to pay much more for that.
This however, at the near-bottom of the Kingston lineup, is just remarkable. Even if you're not thinking of upgrading, £26 will get you two of these, and will really get you back on track with the ever-rising PC standards. If you already have 1Gb (2x 512mb) installed, don't just get ONE of these to replace your old RAM as it won't particularly make much difference. The specs for this RAM is fairly average as things go, so you really need to be buying two in order to make the most of an upgrade.

One more quick note;
Don't be put off by the product title, as it says "PC5300". This should really be PC2-5300 as it is DDR2.
DDR1 = PC-xxxx,
DDR2 = PC2-xxxx

One absolutely final note;
Do make sure you know what type of RAM your laptop takes before ordering, else if you buy an incompatible chip which is either too fast or too slow for your motherboard, you're going to look like a bit of a fool and then need to go through the hassle of returning the product and getting the correct one.
Just a helpful hint to the novices out there :)

Cheers Play.com!

Upgraded my Acer Aspire 5102 laptop with 2 of these yesterday. Vista uses too much RAM for visual Aero effects so i've upgraded to 2 x 1Gb AND to make a massive difference... turned the visual effects off so it just looks like Windows 2000. Worth doing if you dont care about looks and just want speed from your computer!

what can i say having never upgraded a lappy before it was simple as pie, it works straight away so good i brought two, no faults makes my laptop run like a dream, buy now or regret, cant wait till 2gb are this cheap

I was going to splash out on the proper HP ram for my new HP6720 laptop. But another reviewer said it worked perfectly in this laptop. So i thought I'd give it a shot as its a 1/2 of the price. Got it next day. Took it out the package ad slotted it in, job done, worked perfect. for £12.99 its a bargin

I Just installed two of these ram chips into my dell inspiron 1520 series laptop it is working much better now with 2GB of Ram, a perfect upgrade chip and great value for money for Kingston Memory very good deal
