PC won't reconize new memory.

  DWANE PYPE 16:15 04 Dec 2007

Upgraded daughters memory from 1 stick of 512 to 1 stick of 1gb, but according to the PC it is still 446 (onboard graphics). the question is, is it still running at 446 or 1gb, and how do I get it to reconize the 1gb if it is.

Medion: model no MEDMT407G

Thanks In Advance,

module could be faulty...

you could try it in another slot as well...

This 1gb I had in my PC when I before I upgraded to 2gb, so it was ok then, but if it was faulty the PC wouldn't work would it???. but will try Memtest anyway.

thanks for that,

Maybe it's the wrong RAM type for that motherboard. What motherboard is it?

  DWANE PYPE 19:44 04 Dec 2007

The Mobo is a MSI MS6570E(aka K7N2-DELTA2 according to the web site)

The 512 is 5400DDR2
The 1gb is 3400DDR2

As I have said the PC is working all right just not showing as 1gb of memory.

The 512 is 5400DDR2
The 1gb is 3400DDR2

Are you sure you've got that the right way round?

Better info on the ram

512 Is 4200 DDr2 Swissbit(Siemens)
1gb is 5300 DDR2 Novatec's own brand.

Hope this better info.

' The Mobo is a MSI MS6570E(aka K7N2-DELTA2 according to the web site)'

I don't think so. This motherboard just takes DDR1 ram and not DDR2.

Run a crucial scan to see what memory you can fit into the motherboard.

paulC is quite correct -

extract from the K7N2-DELTA2 PLATIMUM spec sheet:-

• Supports six memory banks using three 184-pin DDR DIMMs
• Support Dual channel PC3200/2700/2100/1600 DDR SDRAMs
• Supports both 64-bit and 128-bit DDR SDRAM
• Maximum memory size of 3GB
• Supports 2.5v DDR SDRAM DIMM

Sorry about not getting back to you earlier.

Have now changed the ram back over, before putting the 512 back, looked at the sticker,and this is what was writen on it,

512 PC2 4200U-444.

Somehow my old brain had read the PC2 as DDr2, (one of those senior moments).
But according to your specs DieSse, it does not take 4200 ram, that is if it is 4200.

Will not tick yet, incase of any further comments.

"But according to your specs DieSse, it does not take 4200 ram, that is if it is 4200."

Not my specs - MSI specs.

It's quite possible Medion have their own special version of the board - lots of big OEMs do that. It's also possible they supply the board with PC4200 RAM that's tested and known to work with the board. Some motherboards can take some faster RAMs and run them happily at lower speeds - some can't, and some fast RAMs won't run happily at lower speeds - and the motherboard may have been tweaked from the standard.

There's so many imponderables.

RAM compatibility is not a "cut and dried" subject, unfortunately.

If you've noted the make of the chips on the RAM that was fitted, you might be able to get some more of the same speed/make that would work OK in the board. This board supports dual-channel RAM - and you would need to get matched pairs of RAM to be pretty certain to run in that mode. Also often dual-channel mode cannot be used with the higher speeds of RAM at all.
