question on upgrading ram on laptop

[Father Time]

ive got a vaio v505bx and just ordered a 1gig mem upgrade for it.
I havent had the vaio open but is a multi slot? and if so can i move my one 512 over and run it with the 1024?

it can go both ways, it can have two solts with 256 in them or you'll be lucky and get one 512 card. Make sure you keep your memory speed the same like say you had a DDR 2700 to keep it within that same speed as a 2700. A lot of times the motherboards get really picky on what card you can use, so I hope you did some research before you bought it.

this is what i picked up. i was told it was the correct speed


* 1GB of DDR PC2100 RAM SPECIFICATIONS
* 1GB DDR, 266, CL 2.5, ECC • 200-pin, small-outline, dual in-line memory module (SODIMM) • Fast data transfer rates: PC2100 and PC2700 • Utilizes 266 MT/s or 333 MT/s DDR SDRAM components • Supports ECC error detection and correction • 1GB (128 Meg x 72) • VDD = VDDQ = +2.5V • VDDSPD = +2.3V to +3.6V • 2.5V I/O (SSTL_2 compatible) • Commands entered on each positive CK edge • Differential clock inputs CK and CK# • Four internal device banks for concurrent operation • Programmable READ CAS latency • Gold edge contacts

hmm, I checked out a review for your v505bx and it says it can only handle 1024max of memory.

you can check specs for your laptop here.
it says the pcg-v505b series handles 1024 and oem speed was pc2100.

well i ran into a problem. my stick is a single 1gig stick and my notebook has two 256's installed. I took both out and put the one 1gig in and nothing. tried the other slot and mothing. put the old ram back in and now its fine again.
I got online with sony's tech support and they said i have to have both slots filled (ie 2 512's for 1gig)
I asked "so what would happen if i put one of these 256's in with the 1gig" (total of 1280, my max is stated as 1024) He said its not recomended and might harm the notebook

[cali240sxdrifter]

as I stated before the max you can have is 1024, but thats weird that if you use just the gig stick it still doesn't work...

depending on the design of the motherboard. some have to have both slots filled because the 1gb module is too big for it to use in one slot. You need 512x2
