1GB DDR2 RAM only reads as 512MB


Recommended Posts

I recently bought 2GB (1GB x2) DDR2 PC2 4200 RAM from crucial.com (therefore I believe it's supposed to be compatible with my motherboard) I put one stick of RAM in and it read as 512MB. I put two in and it read as 1GB. Crucial told me to update the BIOS so I did, but with no change. :[  Help?

Mobo: ECS P4M800PRO-M (2.0)

It has happened, but w/ Crucial , man, that would crush my high expectations of them.

I know what you mean, but when he installed one stick he said it only showed 512MB instead of 1GB. I'd really be disappointed with Crucial if they did not accept that as a possibility and allow him to swap it for another kit.

Hey guys..

I read your topic and I've the same problem.

I'm sure that my Kingston module 1Gb is, but my PC still read 512mb. I didn't reinstalled my BIOS because it is dangerous...at least I read that.

My module is a KVR533D2N4K2/1Gb and I've a Fujitsu-Siemens PC, motherboard P5SD2-FM. I couldn 't find the BIOS in their website.

I'll appreciate your help. Thanks.

:cry:

While it is possible to brick the mobo from updating it, its unlikely if done correctly. Especially if flashing from a USB drive which is the safest method IMO
