I just installed a pair of new PC2-4300 1gb Samsung memory modules in my Dell GX280 Small mini tower. This system runs XP 32bit. Before I had the original 512mb PC2-3200 modules. The BIOS is the most recent A08.
I'm a bit confused that both the bios and cpu-z says that the module size is 512mb. But that the total memory size is 2048mb.
Yes the small sticker on them said 1gb and that is what I ordered, both task manager and process explorer says that the total memory is 2095mb with about 1400mb available. Looking at the system properties in the control panel it claims 2.0GB.
You are correct the system is old, originally 2004 when dual channel memory was new, the latest bios is from 2006.
With starcraft 2 running I have 400mb available and SC2 using about 1GB. I guess as long as it actually can use 2GB I can ignore the 512mb statement.
I just looked at the memory modules. The chips says HYB18T512 400AF37. There are 8 chips on each side. Although pcwizard identifies them as samsung pc2 4300 I can't read anything about samsung on them.
I also contacted the seller and he says that I can either send them back for new modules or upgrade to 100% compability modules from a major brand at twice the cost. But I really don't want to spend much more money on this system.
Odd, sounds like the seller may not exactly know what he actually sold (high or low density).
But yeah - it doesn't really matter if your ram is low or high density - as long as it works. I knew of some older computers previously had problems reading "high" density memory modules - but yours seems to be inbetween - detects all 2GB in OS, but not all 2GB in the BIOS.
