Stabilizing 2x2gb ddr2 8500 on a EP45-UD3P

It doesn't work at stock speed (1066). This jump out at anybody? It passed memory test and runs like a charm at 800mhz but if i can't even get it to run stock, i'm not so confident its going to overclock later you know what I mean?

Heres the parts:

Name Core 2 Quad Q8400
Operating Frequency 2.66GHz
FSB 1333MHz
----------------
Model GA-EP45-UD3P
CPU Socket Type LGA 775
FSB 1600/1333/1066/800 MHz
Memory Standard DDR2 1366+/1066/800/667
Maximum Memory Supported 16GB
----------------
Brand G.SKILL
Model F2-8500CL5D-4GBPK

Here's the settings, exactly as they should be set according to everything i've read in the last 3 days and the G Skill administrators (telling other people w/same gear in gskill forum) recommended settings.

FSB: 333x8
Performance Enhance: Standard
XMP: Disabled
MCH Freq Latch: Auto

System Memory Multiplier: 3.20B (1066)
5-5-5-15
Command rate 2
TRFC 68
MCH Core 1.28v
MCH/DRAM Reference 1.16v

DRAM 2.1v
----------

Only runs stable at 1.84 volts and 800mhz 2.40B

not overclocking. memory stock speed is 1066.

However, i've been brainstorming on this... is it possible to have compatible memory that can't run at its stock speed unless the FSB is overclocked to catch up? Eg. my fsb is 333, my (stable) RAM speed is 400mhz(x2=800). When I put my ram speed to 533 that creates a difference of 333 : 533 - could this cause my BSOD? Ratio too far off? I'm a noob so, some things I haven't learned yet.

Ahhh i think i see what you're talking about. See these are the things I wanted to learn by building this system. Glad I did it. Here are the tables. Correct me if i'm wrong, shouldn't memory SAY that it's 800 standard 1066 OC if that's what it is?

Try testing it at the 1066mhz speeds with only one stick at a time. It's possible one stick is faulty and can't run at 1066mhz.

Aight here's an update: it still wont' accept any of these suggestions, and I tried the first jump on Gigabyte's Easy Tune 6 and I could noooot get it to post for 20 mins after that. Sooo... I dunno what I'm gonna do but this thing is kicking my butt.

I run my G.Skills (PC2 6400) @ 4-4-4-12-24-2T / 1.9v and they are faster than my OCZ (PC2 8500) Platinums 1066Mhz @ 5-5-5-15-26-2T / 2.2v ......That has a lot to say about 1066Mhz modules.....

Thanks for the input guys I really appreciate it. So now let me ask you this: you're running 800mhz before overclock? Or total? Because if I want to OC this in the future (which could be a while and a few lessons later since I apparently have NO idea how to do it) I'd like to know that the parts I have will work. Only important parts not listed up top is my 2 x XfX HD 4870's and my PSU is a Corsair TX650W.

It's stable at 800mhz. That isn't a problem. I've been playing some games on it, watching temps, benchmarking, etc. I just assumed earlier that cpu should run at stock speed and RAM should run at labeled speed. But I was n00b =\

Oh and speaking of temps I want my GPU fans (HD 4870s) to run faster than their default minimum which maintains ~61C. I don't like that. I think its too hot. But then if i manually override with catalyst, it will go that speed and only that speed. What overrides catalyst fan speed and does it well?
