Upgrade Memory

I have an ibm t43p 26684-p2u, with 1gb of pc4200 memory. I am thinking about upgrading to 2gb..Is there anyone out there with this system and 2gb of memory? Will I notice that much difference? When looking at Newegg for the memory, I see 2 options. Also the ibm site listed 2 options for me, both the pc 4200 and pc5300. The pc5300 is more expensive and I assume faster.

I would appreciate some opinions on this. Thanks

Jim

I have a different T43 model, but I doubt that makes any significant difference to the rest of the answer.

Whether you will notice a much difference from moving to a 2GB memeory configuration depends on how you use your ThinkPad and what you use it for. Personally, I usually work with a bunch of different applications open at any one time and for me there was a noticeable increase in my overall work throughput in moving from 1GB to 2GB of memory.

Cheers,

Bill

PC5300 is more faster, but only if it is used on a T60. The T43 was designed for PC4200 memory speeds, therefore, the PC5300 will be downgraded to PC4200 if you put it in a T43.

so what you are saying is that it is a waste of money to spend the extra on the pc5300 as it will be downgraded to the slower speed memory?

Thanks

Right. However, if you plan to get a new laptop later on (like within a year) that can support the PC5300 speed, I would get the PC5300 now so you can use it on the new laptop and not have to pay for a new stick.

Buy something that matches your current memory stick ... so as not to screw the dual-channel pooch. Another thread here recently has specifics on that....

So I wouldn't spend more or less on other than the same spec, same capacity, as what you have. That is, if you have PC2-4200 1 GB, get PC2-4200 1 GB.

You may not see blazing fast speed improvements, but if you do some serious number crunching or filters on huge images in Photoshop, then you will see a little turbo-charge.

Happy shopping.

I currently have 1gb of memory in 2 512mb sticks. I was thinking of replacing both with 1gb sticks each. Is tehre anyway of knowing for sure whether I have 2-512 sticks or 1-1gb stick without opening up the case?

Open the memory access cover on the bottom of the unit.

If there's a stick of memory there, you've got 2X512MB.

No memory, you've got 1X1GB under the keyboard.
