Required Voltage for E6600 @ 4GHz

post #1 of 12
Thread Starter 
I have an E6600 running 3.6GHz (400MHz FSB) completely 100% stable (Orthos, OCCT, 3dMark '05 & '06) @ 1.4250 set in BIOS on an Abit Quad GT-13. I actually was running stable at a couple notches lower except the 2nd CPU test on 3dMark '05 kept restarting the PC (go figure).

Anyway, I have a Thermalright Ultra 120 Extreme with a 120MM SilenX fan. I have great airflow and was wondering if 4GHz is possible. I've been able to load windows that high, but SuperPI fails. I'm leery of giving my Conroe to much juice, and was wondering what was considered the voltage limit?

Thanks,

Kevinm207: Please go to user cp and fill in specs (will help all help you and you don't have to retype specs every time). Here is a link to what others are doing according to their cpu stepping:

Good luck!

Well, I'm at work, so what I remember off the top of my head:

@ 1.4250V (set in BIOS) 3.6GHz (400MHz FSB): 28-29C idle, 35C full load

My Case ( LIAN LI PC-A05B) has a reverse air flow, so I'm pushing cool air directly onto the CPU.

@ ?.????V (I've slept since then) 4050MHz (450MHz FSB): ?? idle, 60C full load

At least that's what I remember. I've change so many settings, I can't remember, but I'll post when I get home from work with the accurate settings and temps.

Now being serious, It will take quite a large amount of juice for it to run stable. However, really, I beleive that you will have a new CPU by the time anything happens.

I know to hit 4050MHz I'll need at least 450MHz FSB, so I've been working on that. Right now, I have my FSB set to 450, and my multi. at 7, so I can simply focus on the FSB. It seems that I only need a slight bumb on the MCH (from 1.25V to 1.30V) for a stable system. Next, I'll start around 1.53 vCore, and inch up from there.

I'll keep ya'll posted.

Also, I'll try to get a better list of voltages and temps together asap. There was a discrepancy in one of my previous posts. At 3.6(400FSB) idle is indeed around 29C, but at full load it's more like in the upper 40's (around 46-47C)

This is something that could be hindering me as well.

When I was first tweaking my BIOS, I left Execute Disable Bit, and Virtualization Enabled. If I try to disable them, I get a blue screen. So, short of reloading Windows, I'm stuck with the settings that I have.

My question: Will either of those affect my overclocking capabilities?

Well, I'm officially giving up on 4050MHz for now. I went as high as 1.75 vCore. Ouch! I think it actually did better around 1.7250. Needless to say, without at least water cooling, it ain't gonna happen with my chip. I was able to run SuperPI 1M succesfully for whatever it's worth! I'm stable and somewhat content for now at 3.6GHz (450MHz x 8).

I don't understand how your temps could be so low. What are you using to monitor?
