Hey Guy's I just got a 600X off ebay P3500 128mb 10GB. DvD.
and was just re-verifying that it van run someting like 570MB with the latest bios update. I purchaed 2 256Mb sodims for it for $38.00 bucks apeace, it's the standard 8 chip ram.
(your comments)

I was under the impression that the 600X wanted low density 256MB PC100 chips, not just any old 256MB chips. I've only ever used low density ones in mine, so I can't say for sure if others will work or not. Memory maxes out at 576MB in that setup (64 on board + 2x256).

Hey Phil, thanks for your reply

I sure hope they don't only take low-density. Do you think that these 8-chip moduals will work

Can anybody verify that it will take 2 256MB sodimms?

8 chip sticks will not work. Sorry.

But yes, you can have 576MB total in a 600X. It will take two 256MB LOW density sticks.

Kahlon is selling new 256MB PC100 low density sticks, guaranteed to work, free ground shipping for $66 each. Crucial charges $119 and Lenovo charges $159.

I'm a happy customer of all three brands.

Hey Wizkid. Thankyou for your help

Crap ! I thought only 600 and 600e had to take low density. well I guess I could re-sale them. I saw some low-density ram (2 sticks) for 100.00
(free shipping)

So I guess I'll have to get low-density

So is low-density ram ...(slower). What's the whole deal on that?

The whole deal is that each chip has half as much memory. It's not slower. It should even be cooler... a little.

I have no idea why it should matter at all, but the 440BX memory controller doesn't like chips with so much memory for some reason.

I (being an electrical engineer by training) would think it would be very possible to make a high-density stick appear to be low-density with just a little tweaking, but what do I know?

I know that two used sticks for $90 was a pretty good deal at a local laptop repair shop.

Hey whizkid.
And once again thankyou for your reply.

Really? I have never worked with low-density Ram.
Never had to.

Where again did you see those Low-density sticks?

Well thankyou very much for your help guy's.
