set RAM from 1066 to 1333...?

[somecanadianguy]

I'm running the CPU at stock speeds right now.
I just got it and haven't OCd before so I want to wait a while.

The motherboard is Gigabyte EX58-UD3R...

Ram is Corsair XMS3 3x2GB DDR3 1333 (9.9.9.24)

Cpu-z shows...

NB Frequency: 2664 - 2665 MHz
DRAM Frequency: 666.2 MHz
FSB DRAM: 2:10
CL: 9.0
tRCD: 9
tRP: 9
tRAS: 24

I see that only the CL has the decimal showing.
When I entered the other numbers it asked me to enter a decimal value.
I just put 9 and 24 not 9.0 and 24.0... does it matter?

All of what I posted isn't JUST for OC'ing purposes, its so you understand what you're doing when adjusting your RAM to "anything" but default...

As for Gigabyte Board..hhhmmm...they must have a Support Forum similar to Evga....

I'm in the process of learning...
It takes time though ( I just got this pc together a few days ago and have never OCd before ),
and I find that asking questions to clarify what I've read can be helpful.
Thanks for your replies.

[rjbarker]

No worries...thier is all inds of "help" available here with oodles of knowledge at your finger-tips.....

[somecanadianguy]

oodles...


**edit**
I figured out that only the CL is supposed to show the decimal.
I'll be trying memtest out later, but it seems to be running good.

[somecanadianguy]

I ran memtest86+ and it finished 2 passes without problems.
Don't seem to be having problems doing other things either.
Does that mean I'm pretty much safe?
All I did really was change the memory multiplier and timings to match the RAM specs.
I'm trying to figure out whether or not I have to change anything else... don't want to fry my system in a week.

If anyone is interested I got a response from a gigabyte tech guy on another fourm...

I haven't tested this yet... does it all look safe?
The info came from a gigabyte tech but that doesn't mean he's right.
I've read about DRAM voltage and a lot of people say 1.65v is max... would I really want to set it to 1.66v? It's not much more, I know, but would it have any effect on the life of my ram... or motherboard over time? The specs on the RAM are 1333 @ 9-9-9-24 so I'm guessing that it should be ok with the settings above, but I'm just not sure. i'm also wondering how much my temps will increase if I do this? I'd like to know what to expect so I don't panic when I see it rise a little.
