The same is reported on the specs table in this report ( I must say I'm a bit skeptical that it will work, but I want to try a slower memory anyway.

I sent back my 2x2Gb@667MHz and, the vendor said, my 2x2Gb@533MHz will probably ship tomorrow.

I'll come back with the result. Whish me luck :-)

Hi all.

The modules arrived. Unfortunately, there's no difference with respect to the faster ones: I still get only 3113448 Kb of memory (about 3040.5 Mb or 2.97 Gb) in my system, according to "cat /proc/meminfo". The BIOS sees 3071 Mb (2.999 Gb), same as with the faster modules.

My system does not seem support 4Gb of memory. This in spite of the specs and the fact that Acer Help Desk assured me this laptop supports all 4Gb.

So this is it. I'll keep the modules since I'll use the extra 0.97Gb my system sees, and hope that I'll find something that will make my system use a bit more or the memory I installed.

Best regards

hmm, sorry to hear that; too bad there's not a BIOS update to fix it (or a 3rd party BIOS file). Anyway, 3 gigs of ram is not that bad, I guess .



bigmem, debian, kernel, ram
