New kingston DDR3 1333 running at only 800 bus speed..

Hi There,

I decided to upgrade my pc by adding a new kingston 2G DDR3 1033 kit .. I Bought it and placed it in the same slot color with the old one (kingston 2g DDR3 1033) .. when i turned on the pc it just gave a black screen without any beeps .. i removed the new one, it worked well .. i changed the clock freq. from the bios from AUTO To 667 and 553 and aslo they didnt work .. BUT when i changed the freq. to 400 .. the new kit worked well with the old one

This is my pc spes. without the new ram installed

With the 2 rams installed it Reads 400 MHZ

What should i do ?! Is the New kit is bad ?

Note the old one Model is KVR1333D3N9/2G
and the new one is KVR1333D3S8N9/2G​

Load bios defaults and try again? Its just ram, your system wont be faster because of it running at 667 vs 400mhz, it will be faster because it has more memory installed.

when i load bios defaults it gets back to the black screen without any beeps just fans are working ... I cant get it work except i remove the new ram and change the clock to 400 MHZ an install it again ... What should i do ?!

Sounds like bad RAM.

It will run at 800 but not at the advertised speed. Typical of defective modules.

Send it back.

EDIT: Just check to be sure your new RAM is the correct voltage. It should be the same as your old RAM. Also check that is the same as the old RAM in buffering and ECC.
