Overclocking a e2180 on a DS3 Rev.1

[Bones82]

I was wondering about the memory settings. The memory settings I have available on my Gigabyte DS3-Rev.1 board is 2.00, 2.66.... and so on. How do you go about overclocking the 2180 with tese types of memory steps?

On that board the memory setting is how many times faster than the FSB the memory runs. Selecting 2.00 will give you what is normally referred to as a 1:1 ratio. (So at stock, with your E2180's 200MHz FSB, your memory will be running at DDR2-400.)

For now leave it on 2.0 while you overclock your CPU. Once you've achieved your desired CPU overclock, then worry about ratcheting up the RAM speed if you care to. Personally, I'd just leave it running 1:1 anyway.

With a 2.0 ratio your DDR2-667 memory won't even run at stock speed until you reach FSB of 333 (which will equate to 3.33GHz for your e2180).

If you push your chip to 3GHz (FSB 300) your memory will run at DDR2-600 with a 2.0 ratio. If you change the ratio to 2.66 at that same FSB your memory will have to be able to run at DDR2-798 which is usually doable if you relax the timings. Otherwise leave it at 2.0 and run tighter timings. You really won't see much (if any) difference in most real-world applications, perhaps a bit of difference in Prime or F@H.

OK. Thanks guys. I appreciate the help.
