New memory running at 1333 instead of 1600 like old one

[Songyu]

Hello everyone,

I know this question or similar ones have been asked many times before but
I couldn't find an answer to my specific (but generic) problem:

I have a crappy computer from medion (Medion Akoya P5203 DR) with the
mainboard MS-7797G (msi?).

The installed ram was 2x2gb ddr3-1600 which ran 1600.

I have now exchanged them with 2x4gb ddr3-1600.
However the new ones run only at 1333 instead of, preferably, the 1600.
Note that the old modules run at 1600 even after I put them in again.

I've uploaded a few screenshots from cpu-z here:

Things I gathered and tried:
1333 appears to be the default frequency. But why do the old modules run properly?

Changing XMP profile: I havn't found any such settings in this mainboards bios.

Change memory frequency in bios: It's greyed out and so far haven't found a way to
enable/change it. I found the shortcut Ctrl+F1 to apparently enable all settings in a
thread somewhere here, but it didn't do anything, where ever I tried it.

BIOS update: Whatever this may help: There appears to be no update available for
this mainboard.

What else can I try out?
Any more information you guys need to please help me?


Thanks in advance and
kind regards
Stefan

If your motherboard doesn't support XMP, but the RAM requires it to run at top frequency, then you can't use the top frequency.
Cheap computers often don't have the XMP option available, and you likely can't overclock it to reach 1600 on your OEM board.

I see. And the original ram can reach 1600 because it doesn't need XMP for it?

Pity, that's that I suppose.
Well, thanks anyway!
