Curse

My computer (toshiba laptop) freezes up with the new ram I put in it once I put in 2 sticks of 1 gig. But when I put in just 1 stick of 1 gig it runs fine.

It definitely supports 2 gigs, so I'm not sure why it's freezing up randomly. Any ideas? Also, it crashes in guild wars a lot too with the new ram, but not the old ram.

Computer specs:

1.73 GHz Intel Core Duo
ATI Radeon Xpress 200M IGP

here's the computer, http://www.newegg.com/Product/Produc...82E16834114351

try switching the 1 stick with the other too see if the other stick may be bad.

Well I bought the sticks together and this happened with 2 other brands of ram I had before, but took back. I just updated my post with specs and such.

When you have the old ram are you running 1 stick? it could be ram slot thats bad, also could you post what ram the new ram is.

Here's the ram, http://www.bestbuy.com/site/olspage....=1166840341232

Yeah, just 1 stick with the old 512 ram.

I dont have alot of experience with laptops but maybe try running 1 stick in the second slot to see if the problem happens that way.

HAving recently researched RAm and added 1 more GB to my home CPU I see two things that may be the issue.

1) According to your Machines specs it has 533MHz abilities
The RAM you are adding has 667MHZ abilities though it will be reduced in PC4200 slots.

SO, you may need to get PC4200 RAM IF your slots are regulated for that the PC5300 may just not mesh with it well, notebooks are very fickel

Also there is this:

2) SO-DIMMs have 72, 100, 144, or 200 pins. The 100 pin package supports 32-bit data transfer, while the 144 and 200 packages support 64-bit data transfer. This compares to regular DIMMs that have 168, 184, or 240 pins, all supporting 64-bit data transfer.

Your specs say DIMM, your new RAM says SoDIMM, again this shouldnt matter, since SoDIM is desinged for Laptops, however, again Notebooks are fickle.

Spmetimes you can only upgrade so far, you have to stay within the system requirement parameters.

Kinda like my Truck, It's designed for regular gas, The higer octane stuff is better gas, but my truck runs like shit wiht it in the tank becasue it was designed for the lesser stuff.

That about all I got for imput on that.

In theory, two DIMMs at different speeds will work nicely together, because that's how RAM was designed, to be backwards compatible with that generation.

But that's not how it works out, obviously.

Real world methods have tested that it's not the difference in speed that warrants incompatibility, but the difference in chips, or simply put, manufacturing.

If they're not paired, there's a chance they won't play nice, and your system will crash. This happens especially if you buy inferior "value ram". But please list the brand and part number of your RAM and I can do research to give you some insight.

Hm I see, thanks. What's the difference between PC2 and PC? I found this 4200 at CC, but it's sodimm and 'PC2'

Finding dimm and 4200 seems difficult. Do you think I should just go for the 4200 sodimm?

Pull out the RAM that came with the LapTop.

Figure out what it is, PC4200 DDR2, is my guess, call the manufacturer to find out for sure if you can't tell.

Buy the exact same thing, only alot more GBs of it.

That may be the simplest way to go.

Admael · May 13, 2008, 06:41 PM // 18:41

All laptop memory is SODIMM.

PC2 = DDR2, PC = DDR
They are not backwards compatible, DDR memory is more expensive.

Alright, thanks guys. I'll let you know how it works out with the new ram once it gets in.
