How do I upgrade notebook memory?

Users questions: Buy the Lenovo 2005 notebook, Celeron 1.5GHz, intel855GM chipset, 256MBDDR333 memory (ramaxel memory production). The first is to upgrade to 512MB or 1GB of problems, 1GB memory, a major, but other parts are relatively low , 1GB is not a bit wasteful? Should also consider capacity notebook battery life, 1GB power consumption is not too big? Second, the question is how to upgrade, should think again to buy the memory together with the original, or to replace the original cast of the whole buy my own? Price factors, If I use the ram axel memory, 512MB and 1GB How much difference? Can use other brands of provincial How much? Please the real expert to answer, well I say bonus points. Thank you very much master of the warm solution. We This is a small place, no computer accessories market, I of convenience, nearby in the clothing of the passenger association Memory. Because computers are too old, 512 and 1G of memory are not goods, and only added a 256, 240. Their attitude was very good. I urge everyone to buy our own brands in the world! Lenovo's notebook quality is very good, I have personal experience, spent nearly two years, never out Had a problem. I have seen HP and DELL in the book, to be honest, work too well. 7,777,771, capacity, proposed 1G first thing to consider, your card is on board, graphics card, it takes memory, so a good memory or larger. I started from 256, 512,1 G, 1.5G , 2G I have used, installed XP, feeling no different than the 1.5G to the. The following specific about my experience, your reference: 256 to 512, speed increase is very significant, usually operating, feeling almost doubled. This is because the 256 is too low. But to play great games (capacity, divided Set is the high speed requirements) such as was Xuanyuanjian 4, on the graphics card requirements are very common RPG, but the card may not work. Can reach 1G. 512 to 1G, speed increase is very evident. Into the original Lord of the Rings, rings to 4 rings, expanded to 1G, the turn around and then entered. Usually use a very smooth, almost nothing When the card. 1G to 1.5G, usually nothing to improve the operating speed, but when playing big games, like I like playing the Lord of the Rings, improve significantly. 1G when playing Lord of the Rings, played a major battle, exit the game quite a while the desktop icon, the hard disk has been rung. 1.5G after 1 second on the show tables Noodles, and never played on the same. 2G, I expanded into Vista to play 2G. Feeling under the XP and 1.5G not make any difference. But in Vista, or are clearly different. Because we must account for vista starts out about the memory of 800M. So, I suggest you at least rise to 1G. Because 512 is just enough, sometimes there are points card. Re-occupy some of your graphics card, the worse the. The memory is now very cheap. xp memory consumption is large, with antivirus software, and occasionally a rogue and then the plug-like, after the boot is not much memory available, so not to waste a bit. As for the power , Memory power very small, nothing to consider. 2, compatibility. Ramaxel memory, market, good buy, I am surrounded by several friends of Lenovo and HP to upgrade books are retained ramaxel, plus a Kingston, very stable, very good compatibility. When you buy and the merchants say, OK, If not compatible, great article on the exchange. He can even discuss what discount the old memory. However, I suggest you first try to use genuine Kingston. Sell notebook memory business I know, he said all kinds of memory, the number of Kingston's compatibility better. Memory mix of old and a high probability of success. He gives the books in the upgrade Only Shenzhou defects more. There is also a key to use. If there is a slight memory is not compatible, you into the bios, the memory speed to reduce the number. You are now DDR333, the market is basically all DDR400, then, in memory, do not use auto or by spd, and to hand to DDR333, or other low-option so that compatibility with different memory speeds will be greatly improved! 3, the price. DDR, 512 is the memory of about 250 or so, 1G doubling. The small gap between the price of the brand is 5 10's. Mainly Compatibility, no other essential difference. Do not buy no-name like. Kingston fake a lot, we must find a regular agent. On the supplementary questions: 1,855 does not support Hyper-Threading, does not support dual channel. No way. 2, DDR333 is 333 internal and external is 166. That is, board FSB is 166, because DDR is double inside, so then x2 is a 333.
