Yet another question from me.

First of all, I'm beginning to wonder if the guy who upgraded my PC is BSing me because he knows that I'm not very computer savy, or am I missing something here.

I have a question about the DOMINATOR Memory he installed in the system. From what I understand, he has installed 2GB's of Corsair DOMINATOR DDR2 1066MHz. I was using PC Wizard to see what exactly he installed, and I'm not seeing anything about 1066MHz anywhere. I see a whole bunch of other MHz's, but no mention of 1066MHz. If it matters, this memory was used.

Here is a copy of what PC Wizard is telling me about the memory.


General Information :
DIMM0 (BANK0 ) : 1024 MB - DIMM
DIMM1 (BANK1 ) : 1024 MB - DIMM

Information SPD EEPROM (DIMM0) :

Cycle Time (tRAS) : 15 clocks
tRC : 22 clocks
tWR : 8 clocks

Memory Controller Information :
Memory Controller : System Memory
Location : Mainboard
Error Correction Capability : No
Number of connectors : 4
Max. Module Size : 8192 MB


Does everything seem correct, or is there some way he could have adjusted the memory to be compatible with the motherboard and/or processor?


Thanks in advance.

Also, if I do a Google search of the part number listed above, it lists the memory as PC2-8500. But if you look above, it has 8500 as part of the part number, then under "Type", it says it's PC2-6400. I'm very confused.

It is 1066 rated RAM running at 800. CM2X1024-8500C5D means you have the memory you paid for.

I am a retired Ford tech. Next to Fords, any computer is a piece of cake. (The cake, its not a lie)

3770K @4.5, Corsair H100, GTX780, 16gig Samsung, Obsidian 700 (yes there is a 700)

I'll just add a note that RAM will not necessarily run at its optimum speed...that's controlled by the motherboard. Sooo...installing faster RAM than the board supports...yields nothing exceptional in terms of performance.

Very helpful. Something I did not realize. Thank you.
