XP 32bit only shows 3GB with 4GB installed

[OnBoard]

hmm why does your bios say that you only have 2.9 gigs of memory? this seems more like somethings wrong with your ram/board rather then windows?

That's where you need that memory remap option, then it shows full 4gigs, but that somehow messes windows to lose 1 more gigabyte of memory.

Should try those black slots as well someday just to be sure, they haven't been is use yet. But don't have the energy now, got my OC working with these modules too 417MHz goes with 1.9V at least TPU stable 5-5-5-15 compared to 4-4-4-12 with G.Skills, so don't know if this was a upgrade or a downgrade

it has to do with pci devices they memory allocated to them and whats left windows or whatever os gets

A little update, the other stick of the memory died after 12hours, so now I've really got just 2GB Couple hours of BF2142 gaming was fine, it was smoother with 3GB than 2GB and closing the game resulted in no hdd swapping like it usually does. Then after 9 hours programs started getting errors, then crashing, then blue screens.

Win memtest gave 156 errors in 1%, tried with just 1 stick and hardly could start Windows, antivirus crashed istantly and said definitions are corrupt. So I'd say it's pretty much done, but will do memtest later. Now surfing with the other one just fine, have to try and "brake" this too

Been there done that

I've tried playing around with the concept 4g in 1g sticks..............to no avail so I took out the extra 2g and am running fine as is. X86 32bit systems simply don't run much better with more than 2g of Ram (you might see a benefit in multimedia intensive apps).

I was running 2 xms2xpc6400c4 corsair 2 g kits never had errors and never blasted them (never over v'd them more than .2v more than given max of 2.1v)
