Ok. I am using a Toshiba laptop with a Pentium 3.33 with HT and a 93 gig HDD and 512 Mb of memory....I would like to upgrade the memory. Would it be better if I were to get another 512 or a 1 gig? How do I figure out how many pins I need? And if i get another 512 should I get the exact same model that I already have? Thank you for your time and i look forward to reading your replies.

if i were you, try on getting the 1 gig already, it doubles the speed of your 512 mem if you add another mem. for the pins i'm not sure with it, sorry dude.. hope this could help.

I have 2x256 Mb, should I take them both out and put in a 1 gig or leave one in with it?

What I would personally do is get another 512 Ram and then get an external 1 gig for memory just because it would allow your laptop to still work as fast and not overburn it with the added internal memory.

you can get external memory? do you know from where?

Hi Hobo,
Some computer brands "prefer" matched memory cards from the same manufacturer(IE. ALL CARD THE SAME SIZE ..EG. ALL CARDS 128mb ETC) .. others don't care. Check with Toshiba to see if it matters.. it probably won't. It shouldn't matter how you match the sizes... because all newer computers (P 1 and above) don't care if you mix n' match different memory sizes.
Just put the largest size memory card into the slot that your computer accesses first (see the users manual) as this usually gives you the best memory performance on some brands.
Hope this helps

Don't forget to check the maximum memory that your motherboard can support. In general, the new processors use 168(I think)-pin DIMMs, but there are different speeds and categories, so you'll need to check with Toshiba. Especially with laptops; they sometimes use different types from vendor to vendor. I would expect that it probably uses RAMBUS ram, but it could also use DDR SDRAM.

external memory? yeah right...

I would see if the store can take back the 256 modules you have and give a discount on 2x512 modules. You can use a program called CPU-Z to identify what memory your system is currently using. As for the pins, it is probably a 200pin SO-DIMM. but depending on how old it is, it could be a 144pin SO-DIMM. The 200s are used for DDR and the 144s are used for SDR laptop memory, although I think there is now DDR2 memory as well. You'll need to check with the manufacturer to confirm.

u ve had 2*256Mb,if u want to change them to 1gig.u have to remove the 2*256.and buy 2*512Mb.so the old 256Mb is wasted.
I heard the news that someone have compared between 2*256 and 2*512 to see that how speed 1gig faster then 512?
the result is theirs distance is so close.
I suggest u have no need to do that!!

Dude, memory wont make your machine faster then it is now. Listen, look at your memory when your doing normal internet stuff. If it's below 30% then your fine. But when your gaming and it lags, then get as much as you need or can afford.
