I have a 2gb stick of DDR2 w/ low cas 4 pc2-5300:

too much?

cpu-z currently reads 2x512mb pc2-4300

Go to Crucial and search memory upgrades for your specific laptop.

That's not too much. 2GB is about right. I'm familiar with the Pentium M. Your memory limit is up to your chipset. However since it's only a 32bit CPU you're limited to under 4GB... in the real world it's usually between 3 to 3.5 GB. As long as I can remember nearly all Centrinos during that era max out at 2GB. Also from what i remember, that 2GB may not work well or at all. You'll want two 1GB sticks since you want to run dual channel.

I had a M740 in my laptop (in sig below) before I updated it, I have 2x 1GB Crucial DDR2 in it now (up from 1x 512MB,) but I put that in as part of the upgrade when I replaced the CPU, so I don't know if it would work with a single stick of 2GB, but I don't see why not.

...stab it in and try...

my thought as well: 1gb and 1gb. how many timing tables would a high end cas-4 667 have? I'd assume 3-4, given it is mobile. The one a clocking down, the one w/ compatible timings below sold speed, the reported timings, and maybe a clock bracket ahead. Will a potion of this at least show up- no damage form trying, right? Which is better: 2x512mb, 1x2gb, 1x2gb + 1x512mb? 2.5gb? CPU-Z says dual channel, but no synchronicity. I am running crystalcpuid on the dothan 1.73ghz single-core and the installed memory is steady at 141mhz(x2 right?), 266mhz, and one other speed runnign at 4-4-4-12.

 

[Charlie98]

Yes, 141MHz x2...

I would probably just try the 2GB card by itself, I don't think I would mix-n-match the sizes.

FWIW, I got that nice 2x 1GB Crucial DDR2 from the 'egg for about $30 delivered, and no problems. That and the faster processor really, really helped the old tired lappy out.

like butter.
that single-core chip reads ~50% memory usage of 2gb- 266MHz at 4-3-3-10 according to cpu-z. only one dimm populated- single channel mode. dare I see if it have do dual-channel asynchronously with a 2gb and a 512mb?

 

[Charlie98]

You could try it... I have something like that in my old Dell Pentium D... 3x 512GB and 1x 1GB... just to fill every slot.

Hopefully you will get the same response I did... it's like a new computer. I bought another set for my mom's Vaio... she's stuck with a 1.60GHz T2050... and needs all the help she can get.

cpu-z reads it, but neither bios nor the xp installation see 2.5gb. Though, in the "sys info" display, it reads PAE, so wouldn't the range of addressing be closer to 3+gb? Chipset limitation?

 

[Charlie98]

Chipset limitation?

Must be...

 

[Charlie98]

I pulled mine up... (laptop in sig) and I get dual channel in CPUz, but that's with 2x 1GB, 4,4,4,12 @ 266MHz.

That's with the 770 CPU, not the 740, obviously, and with 2 cards. I don't recall what it said when I only had the one 512MB card in, but I'm almost positive it was still dual channel.

now i have a ocz and a hynix i no longer want. lolrz. i want my hynix no longer.
