anyone wanna help this guy? He needs to underclock his RAM right? But i cant find the settings for UC'ing the RAM in the ud3p (he's go it too). I'm not very experienced in this area, so maybe ya'll can help him?

4) Im just trying to hit 3.2ghz with 800mhz as rated on the ram

The RAM dividers are referred to as "MCH Strapping" section of the overclocking section of the BIOS. It's kind of strange to look through if you've never clocked RAM in that way. The actual setting to change is "System Memory Multiplier (SPD)" in the "DRAM Performance Control" section of the M.I.T. section.

Your options are going to be listed as
x.xxA
x.xxB
x.xxC
x.xxD

wherein the x's are the actual divider and A, B, C refers to the closest clock speed to what you have. In this case, given his FSB, the closest 1:1 MCH strapping option is 2.00B which is meant for a 333MHz FSB (give or take a few MHz). Neither A, designed for 266MHz nor C, designed for 200MHz has a 1:1 option as far as I can tell. In order to get 1:1 with DDR2 RAM, though, you have to use a setting of 2.00Someletter, so I'd try 2.00B and run some tests.

EDIT: Just noticed that "Jinx" is trying to run his RAM at 800MHz rated. If you want a 1:1 FSB and RAM you need to set your FSB to 400MHz and your RAM Multi to 2.00D - if you want to go that route, however, take it slow! A few MHz at a time will help you find the sweet spot for your CPU. I can tell you right now this board'll EASILLY hit 400FSB, so you'll want to focus instead on loosening the timings on your RAM and watching the CPU each time you up the FSB - run a quick stability test each time. If your CPU can take it, those are the settings you want.

Also, on the RAM, instead of leaving the voltage on "auto" I suggest manually setting to 1.8V. "Auto" likes to do adjustments on its own sometimes.

I just ordered it. I hate the hardware midgets.

thats the right path

It handles memory dividers differently than asus boards.

here is an example of 1:1 on a test run with my E8600 (at 400 FSB 10x multi)

Selecting the various multi's takes you back to the main shot (third slide below) where is says memory frequency (1066 and 800) means its 1066 ram running at 800 Mhz. Choosing other options will change the second number which is the actual speed the ram will be running at.

Got the rest of my RAM in and now running 3.6ghz with 6 gigz of RAM.

That is just annoying

$100 USD = about $123 CAD. It lists here for $190...

newegg.ca Has it for $147 before $20mir w/ free shipping.

Only catch is the page has it shipping with a 2gb flash stick which newegg tries to charge you shipping for the stick, prob a problem with the technical side of the page. I talked to a CSR in live chat and they credited my CC the shipping funds back, which means you get free shipping anyways.

just picked this board up. Excited to try my hand at some OCing. Anybody recommend good ram for this board? Will any G.Skill RAM do?
