Hello,

i know this question was asked a lot, but i still dont get it, if its normal or not..

This is the situation: Yesterday i had a single Kingston 2GB 1333mhz ram (which was working at 800mhz, guess that would mean my ram is 1600mhz but its not, so idk about that..Today my other 2gb kingston ddr3 1333mhz arrived, and at the service they told me its 1066 (which i highly doubt) and now my pc is running at dual channel 4gb but its 400mhz, which is like 3 times lower instead of 3..Is anything wrong here or the dual channel splits it even more or what?

I wouldnt like lectures about what ram does, and how does it work, since i dont understand anyway, just a blank english explanation if everything is alright, and if the memory is still TECHNCLY still working at 1333 or whatever..

My mobo is: msi g41m-p26
My cpu is: Intel Pentium E5800

Thank you.
 
Your Pentium is running at 800Mhz https://ark.intel.com/products/42802/Intel-Pentium-Processor-E5800-2M-Cache-3_20-GHz-800-MHz-FSB
Now as you have Dual channel Memory that means if your single channel was 800Mhz now it runs 400Mhz x2 because you have 2 sticks of ram.

For ram rated at 1333Mhz whats needed for run on its full potential is your cpu limiting that. THat means if you wanted your ram to run 1333Mhz your CPU FSB should be 1333Mhz.

Short story its better than Single 800Mhz.

So for example i can take 3000mhz ram (i know i cant but theoreticaly speaking), and if its single channel it will run at 800mhz, and when in dual half of that.. Aright so i should change the cpu to unlock the rest pretty much?

Im not REALLY about to update anything at this point, but the point is, the cpu is the culprit right?

Take a screenshot of your memory tab. Don't think I can specifically see what the RAM is running at from SPD values there. The SPD looks fine at any rate.

Keep in mind DDR means Double Data Rate, so any MHz values associated with RAM will be doubled.
