Did I accidently overclock my RAM?

[iamfett]

I performed a (first time) mild overclock on my Q6600.
Didn't adjust any voltages. Only turned off EIST, raised the FSB from 266 to 334. Left everything on auto.

This is my memory:
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

Brand G.SKILL
Model F2-6400CL5D-4GBPQ
Type 240-Pin DDR2 SDRAM
Capacity 4GB (2 x 2GB)
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Timing 5-5-5-15
Voltage 1.8V - 1.9V


CPUZ shows it running at a 2:3 ratio.

This is waht I see in BIOS. DRAM speed reads DDR2 - 1002?
Shouldn't this read 800 or 400?

No Blue screens or anythings, seems to be stable.
How do I get the 1:1 ratio?

This is a screen while running Prime95 - everything look alright?

Yeah, you OC'd your ram. Go back into the BIOS and change the memory divider to 1:1.2. Also set the PCIe frequency to 100. Keeping it at 110 is going to hurt your vid card.

Alright, set PCIe to 100
Chose 1:1.2 (which came up as 801 for ram?)
But now CPUZ shows 5:6 as my ratio.

Yeah, you're running DDR2-800, so 801 is fine. As for it showing 5:6, simple math would tell you that 1x5=5 and 1.2x5=6 hence 5:6. CPUz only shows whole numbers for the ram ratio. Like before it was 2:3, in reality it was 1:1.5.

Like before your ram was running at 1002Mhz. 1:1.5 ratio. 334x2x1.5 = 1002. Now it's at 1:1.2 so 334*2*1.2 = 801.6.

See what I'm saying?

 

[iamfett]

Yea, I think I understand. But where did you get the multiplier of 5?
Thanks.

because 1:1 is the same as 5:5. The 0.2 turns that into 5:5 so that it can be shown as 5:6 ratio (equal to 1:1.2). It's just the way CPUz turns everything into whole numbers. You can figure out the divider set in the bios when looking at a CPUz screenshot by dividing 6/5=1.2

1x5=5 and 1.2x5=6 hence 5:6. CPUz only shows whole numbers for the ram ratio. Like before it was 2:3, in reality it was 1:1.5.
