Unganged memory ??

Dwarf said:

What does the SPD tab report as to the memory capabilities? It sounds as though the effective memory frequency is 667MHz (remember that DDR memory transfers data on both leading and falling clock edges, resulting in an effective doubling of the actual clock rate), which would tie in quite nicely with the speed you report of 334.9MHz.

Thanks Dwarf,
Where on the SPD tab would I see that info. It initially shows slot #1 with a Max Bandwidth of PC2-6400 (400MHz). Appreciate your helping clarify!!

CPU-Z shows 669.6 MHz for DRAM Frequency under the memory tab for my PC 10700 DDR3. Thats why I wondered why his only shows half of that? Now I'm confused?

I am only running DDR2, could that be the difference?

Ops my bad, your RAM is slower than mine. Your RAM is PC-6400 (400 MHz) and mine is PC-10700 (667 MHz). 334.9 MHz was close enough to half of 667 that it sidetracked me. Still I think it should be 400 MHz and not 333 MHz? I'm not sure why its running at the slower speed though, unless one RAM module is only 333 MHz RAM.

EDIT: Or your motherboard only supports 333 MHz RAM.

Howdy,
Using the CPU-Z, all the ram is supposed to be 400 mhz! It will accept PC1200 chips according to the box. Hmmmmm.......

PC1200? I tried to Google that and it refers to it as RIMM 2400 which is Rambus?

My fault, they are called DDR21200+. I assume it means ddr2 memory running at 1200 MHz. Sorry!
Glenn

May I ask what the motherboard make and model number is?

Sure, it is a gigabyte ma785gm-us2h Rev 1.1. When I bought it it was to upgrade, except technology jumped past me too quickly, won't take ddr3........

gigabyte ma785gm-us2h Rev 1.1. >
Support for DDR2 1200 (OC)/1066(Note2)/800/667 MHz memory modules
(Note 2) Whether 1066 MHz or above memory speed is supported depends on the CPU being used.
GIGABYTE - Motherboard - Socket AM2+ - GA-MA785GM-US2H (rev. 1.1)

I hope I got this right, all these numbers are giving me a head ache.
DDR 1200 (600 MHz X 2) is PC 9600, your RAM is DDR 800 (400MHZ X 2) PC 6400. If I got the math right, that would indicate that it should be running at 400 MHz not 333 MHz. Your motherboard supports that speed and higher. The Phenom II supports it too. BIOS setting not correct? The BIOS should display what speed your RAM is running at during the POST. You may have to disable the "quick post" or "quick boot" option in the BIOS along with the "display full screen logo option", to actually see it.

EDIT: Sorry for the small text, the font size must have got changed when I clipped and pasted from the web page. I didn't see what happened until I posted it.
