Just set up my Core 2 Duo yesterday and as soon as I made sure everything worked fine, I started to overclock. It took me a while to figure out the ASUS BIOS, but I finally found what I needed tucked away in this Jumper Free Compfiguration menu. Hearing that 6600s can get to 3.0ghz easily on stock voltage, I jumped straight there from 2.4ghz. I tested stability with Prime95 for 2-3 hours and then started overclocking in 10fsb jumps, testing to see if it would boot. I ran a stability test at 3.1ghz, at 3.3ghz, and finally at 3.4ghz all with prime95. They all passed it just fine. The final stability test at 3.4ghz was about 8 hours long. All was well and I had been monitoring my temps (about 45C idle and 52C load). I set my voltage to auto which kept it at 1.38v idle and 1.45v load. I also left all of my memory stuff on auto for the time being and my BIOS automatically kept a 1:1 ratio with my RAM (it did underclock it, though). <br />
<br />
First Problem:<br />
Here is where my questions come into play. First, I couldn't find out how to change my memory timings anywhere in that damn BIOS. CPUZ kept telling me that they were 5-6-6-18 when they SHOULD be running at 4-4-4-12 (RAM does use EPP). When buying this RAM, I heard some people say that they had to change the timings manually. Any help on this would be nice. My profile is correct.<br />
<br />
Second Problem:<br />
After I was convinced that I had a prettu stable OC, I wanted to run 3Dmark06. I opened up the program (all the while having Asus AI Suite monitoring my temps) and as usual, it did the thing where it detects my hardware. All of a sudden I see my clock speed drop to 2.26ghz. My FSB stayed at 377, but the multiplier dropped from 9 to 6. A second later, to my relief, it went back to 3.4ghz with my normal multipler. As soon as my hopes were back up, it dropped down to 2.26 again and stayed there even after I closed 3dmark. After that, CPUZ wouldn't launch even after several reboots. I kept getting the standard "program has encountered a problem and needs to close" error.<br />
<br />
I also could not find the multiplier in my BIOS. I did find some CMOS ratio thing that was set to 9, but that's it.

For the RAM timing problem, try to find a setting in the BIOS that says something like...configure RAM timings by SPD and disable that then you can change the timings. I'm not sure if that's how it is on your board but give it a try. <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" /><br />

Not sure aboutt he 2nd problem.

It seems that CPU-Z is okay now and it is still reading my core speed at 3.4ghz, but why is AI Suite seeing that 6x multiplier?

Here is a screenshot of the RAM timings. Depending upon the BIOS ver you ought to find it under "Northbridge Chipset" menu.<br />

Sorry for the double. But you might want to check these settings as well.<br />

when u open cpu-z look where it sais revision, if it sais c1 then that automaticly lowers ur clocks if the speed isint needed, its a power saving "feature" i was upset when i didnt get c1 on my pentium d 950, but now i am thank ful, although c1 gets a 2% performance boost stock as long as the speed stays up, i might be confused with another technology but i am pretty sure that is what the c1 stepping is<br><br>
edit: ram timings are found in the bios just look at every option, i just swiched to asus from gigabyte and i still have to check every option to find my clock speeds

I can't stand that ASUS AI program. Avoid it at all costs. Between CPUz and PC PROBE II, you should know everything you need to know without freaking out the motherboard.

I tried changing my timings in BIOS, but everytime I touched the automated SPD settings my computer wouldn't boot. Even if I just turned it to manual, but didn't change any settings. What's the deal?

Did u disable intel speedstep? I think thats wut is making your clock speed go everywhere. I have the same ram as you 5-6-6-18 =/ I tried to set timmings manually but it will not post -_- not sure how to fix it.

i fixed my timmings! yay. Try changing the ram slots.<br>
Mine is:<br>
ORANGE:<br>
BLACK: X<br>
ORANGE:X<br>
BLACK:<br>
Then set the timmings manually<br>
I thought it was suppose to be same colors of it to run on dual channel. Dual channel still works with different colors.
