CPU-Z versus my build

[SanDiegoPC]

I've got an Abit IP35-Pro and a Quad 6600 @ 3.2Ghz. Corsair PC-6400 RAM which is labelled as 2.1V and 4-4-4-12

My computer runs fine and I'm glad it OC as easily as it did. My question regards the reporting of CPUID for memory:

On the SPD page, it correctly reports the memory including the PN, type and speed. On the bottom right of that tab, it says that EPP#1 has the following settings:

400MHz
4.0
4
4
12

That so far, agrees with the label on the RAM sticks. 4-4-4-12

But then, over on the MEMORY tab, it shows these timings:

400MHz
1:1
5
5
5
18

So what gives? Is the SPD tab reporting on what the actual SPEC is for PC6400 and the MEMORY tab showing what my system is doing ACTUALLY?

You need to manually set the timings in bios. You will also need to increase your voltage to 2.1v in the bios.

Thanks Yoxx but I've tried. Won't boot when I tell it to go 4-4-4-12 and yea, I do have to proper voltage. In fact I have the V at 2.125 or 2.15 can't remember.

So was my original asessment correct, that the SPD tab (what's that stand for, speed?) the program is report just generic spec for the type of RAM? In the MEMORY tab it's reporting what it actually SEES?

I'm using CPU-Z version 1.42

SPD is information on the RAM, if the mobo cares it can ask the ram what the settings should be and it gets this information through SPD, so cpu-z is just reading that. These are just timings that the manufacture puts on the ram at a given FSB speed. Instead of adjusting the timings yourself you may be able to set your bios to set the timings per spd (auto, standard, they may call it lots of things)

The cpu-z memory tab is reporting what the memory is actually set to.

My guess is that you were getting the cas 5 timmings with a default voltage of 1.8 (though it seems like a bit of a big jump to go to 1.8 to 2.1

edit: you won't notice a difference between the two sets of timings. If you are running fine, then I wouldn't mess with it.

Not in this particular case; from the time I first booted it up as a virgin PC, I set the memory voltage to 2.1 because it's stated right on the modules.

ok, so if you set it then it was in a mode that did not listen to SPD. So either auto it and see what you get or set it yourself, or ofcourse you can just leave it as is. But i think you were asking more about what SPD is rather then what to do with your computer.

SPD means Serial Presence Detect

Thanks again - that's what I was looking for. I was sure it wasn' short for "SPEED."

I'm going to leave it the way it is...the machine runs so good that it's going to be hard as heck to improve upon...and I know that tightening up the memory settings would not change my 'seat of the pants' feel of the way it is.

-errr, at least I'm *sure* that it's not going to change things enough to feel.

Have a great weekend! I'm going to enjoy this thing!

chaning the speed won't change the way it feels.

Dun break what dun need it.

yes you have to BIOS set these only Nvidia mb will auto set for you.
