My memory is Corsair CM2X1024-6400C4, 800 MHz. I need some help understanding this. I used PC Wizard 2007 To view several system information details. This is the first one to get my attention. Part of the information seems correct as to the actual memory installed and some is not. My memory says 800MHz and the setting are 4-4-4-12. The information below suggest otherwise. How do I fix this? It has to be slowing my rig down. Thanx now for any advice you can provide.

Hi,

Everything seems right with your memory.

Here is the explanation:

Clock: DDR, DDR2 and DDR3 memories are labeled with double their real clock rate. DDR2-800 memories run in fact at 400 MHz transferring two data per clock cycle. You memory is running at 399 MHz, so it is running at the right speed. BTW. I suggest you to run CPU-Z and click on its Memory tab to double check this.

Timings: Your memory is labeled as 4-4-4-12 timings and the program you used says that it has 4-4-4-13 timings. Again, I suggest you to run CPU-Z and click on its Memory tab to double check this. To correct this slight difference you can enter the motherboard setup and look for an option like "memory timings" or similar, change from "auto" to "manual" and enter your memory timings.

CPU-Z can be downloaded from:

I hope I have helped.

Cheers,

This is what the memory tab shows in CPU-Z. If I am seeing this right it says 5.0-5-5-18. The last two numbers I don't understand. I cant understand why two different programs would list the memory settings that different. I will go iinto the BIOS and see if I can locate something for memory settings. Thanks for your assist. I will check out BIOS now.
