View Full Version : Memory purchased not the correct speed...

With the new CPA that has come about on the 1st of April what are my rights if I buy memory from a company and they sell me the WRONG type?

Its DDR2 2Gig dimms but they said it is 800 and what I have now under cpu-z is 400

Thats quite a little bit of cheating in my eyes.

Any suggestions?

Please post a screencap of the CPU-Z report

Probably running 2T (2 X 400)

Yes its running 2T is that then correct?

It is correct. Post a screencap of SPD as well

Is there much of a performance hit when its 2T or wont I even notice? Just needed more RAM as PC was grinding...

Thanks for letting me in on 2T :-)

its got to do with the bus speed, most ram runs @ 2T. I'm no expert, played around with my old DDR2 1066 ram to get it running more than 800 (old PC). Was years ago ... Now I have DDR3 1600 ram on my new board and its running way off and at 1T... Will have to sort it out ...


Command RateThis is the setting that selects the speed of the SDRAM signal controller. If set to 1T, then the memory controller is running in synchronization with your bus speed. 1T will increase your memory bandwidth but a LOT of memory brands will really have trouble running this at decent speeds. This setting will have to be played with a LOT while your increasing your FSB speed. It does in fact increase your memory bandwidth but will often lower your max bus speed so much that it just isn't worth using.

the clock frequency of DDR ram is always half the data rate, it clocks data on both the rising and falling edge of the clock - thus "DDR" or double data rate. So you are getting the full speed of your RAM, which is exactly what you paid for. No fault at the supplier.

That makes more sense .. shot P924. So I must calculate my DDR3 as in 1600 / 3 ...

EDIT mmm not sure about that ... its still DDR (regardless of whether its 2 or 3) ag will check when home!

Thank you everyone!

Beers are on me tonight

@IRG: No.
DDR3 is still just Double Data Rate. So CPU-z will report the memory speed / 2.

eg. DDR3 1333MHz will be reported as roughly 666.7MHz in CPU-z.
