Help me overclock my e6600 and 1ghz ram!

So I have an A or B stepping 6600 ( think B, overclocks very well)
My mobo is a p5w-dh deluxe.

I have gotten 3.0ghz by doing 9x333fsb, AND undervolting it to the lowest my bios allows!

Problem is, whenever I go higher, say 8x400, it craps itself WHEN i try to go 1:1 at memory. The cpu will run fine at 3.2 if I back the memory down from 800. I am running stock 2.2v into the ram. I have to reset bios, and restart all over again.

I'm not really concerned about my cpu speed, but more concerned about getting my RAM speed up.

I have a 2x1gb pair of Crucial ballistix pc2-8000 (1ghz). It works fine at 666mhz (333x2), but like I said, when I try to do 800mhz (400x2), it craps itself.


What is the problem? Could someone please tell me what to set the chipset voltages at? I think this may be one of my problems. Also- should I loosen the timings?

Also- would it be better to go 9x355 to get to 3.2ghz? Would running ram at 710mhz be better?

Please help! Thanks!

Why not run the ram at what it's supposed to be? Going for a 1:1 with slower ram I doubt is going to speed the system up anymore seeing as how much faster it is if you run it stock...

I think you have the memory settings confused. Use CPU-Z to check your memory settings. You should be using the 1.0 memory multi, which makes your FSB and ram mhz the same in CPU-Z. The DDR2 rating is 2x ram mhz that shows in CPU-Z.

Your ram will be good as long as you keep it under 500mhz per CPU-Z

If your showing 666mhz ram in CPU-Z, your overclocking the ram to DDR-1332, which is a monster overclock on that ram.

I realize this, thanks though. Right now at stock (Had to reset bios the other day, havent begun to o/c again), my memory frequency is at 267.1mhz in cpuz, like what it should be. This should give me an overall memory speed of 533mhz.

Question is, why does the system fail to post when I bump the fsb to 400mhz, making the overall memory run at 800mhz? This is only %80 of what my memory is capable of!

Like I said, the system runs fine when the fsb is at 400, its only when I have the 1:1 multiplier that it fails to post.

This must have ment that I was using a high to low ratio? like 1.5:1, making the ram run at 600 mhz?

What can I do to the chipset voltages or mem. timings to make it post?

Memory and cpu dont need more voltage, so what gives?

Keep the multiplier @ 9 so that you don't stress the board as much with a high FSB.

Look for the NB and FSB voltages in the bios settings. Up 1 notch.

Give them a little boost. Those 2 are needed when overclocking.

About the RAM, make sure that you set the timings manually to 5-5-5-15

Disable anything Throttle or spectrum related in the bios as well.

Set your CPU Voltage to 1.3V - 1.35V

Set your FSB to 350 and for the RAM, you can use any of the speeds listed under the RAM settings that is below 1000mhz.

And even then, Ballistix RAM can overclock to 1200mhz or so in case you wanted to try going higher than the original 1000mhz.

Thanks for the instruction! Only problem is that my NB and FSB voltages are set to Auto right now. One notch up would be less than normal voltage?

I say that because thats the way it is with cpu voltages.

Well, in my board, 1.4V for the FSB voltage is what I use for a 350 to 400 FSB.

You can try setting it to 1.3V or 1.4 if the first doens't work.

For the NB, I would also use the same 1.3V or 1.4V (whichever is available)

Thanks, i will try this

I found I got faster SuperPi times when I had my Corsair XMS2 PC8500 at it's stock speeds 1066 5-5-5-15 2t and a 3.6ghz OC 9x400 than I did running it 1:1 with the CPU. So I can't really understand why you're trying to do this?

Since you have the 680i board, I would run the memory unlinked at it's stock speed of 1066 with stock timing and volts. Then you can focus on your CPU speed without worring about the ram.

You will likely have to up the vcore to get it stable at 3.2ghz and higher. The newer batches of chips aren't clocking as high as the older ones and require more vcore. For awhile it seemed that 3.2ghz on stock vcore was common, but not anymore. Seems with the new chips anything over 3ghz takes more vcore.
