Northwood (D1) what to expect?

[I'm Obese]

Hi, what can I expect for an OC from my Northwood D1 stepping CPU chip? I'll be pairing it with a AI7 motherboard.

Thanks.

In my opion I would say 3+ghz. My 3.06 will do 3.56 ghz.

Is it correct that I should keep my voltage under 1.65? I read that in this forum I think. Maybe 1.6 - 1.63/4?

Some people say 1.7250, some people say 1.6, some say 1.65... I say 1.65, depending on flucuations and droop of the board (same idea).

Either way, I'm not sure how the 133fsb chips OC... I know the 200FSB D0 and M0 steppings are absolutely disgusting (in a good way, meaning MONSTER) overclockers, heh. I have a D1 stepping NW, 200fsb (3.0C), and i've gotten it to 3.6, I think that was the max though

I had one of those 2.66 Northwood C1 stepping once and it did 3.2 gig with good cooling and extra voltage. So, the D1 should do even better. How much vcore to use depends a lot on your cooling and how much of a risk you want to take. I'd say up to 1.6v is pretty safe. I don't recommend anything over 1.65v

Ok,

I was gonna wait until the AI7 board arrived to OC this chip but I went ahead and threw in this dfi board we had laying around here.

I have it at 3.25 dual prime stable. I didn't run it over 10 mins but it plays games without any problems so I'm not worried about it. I have my voltage at 1.67 in the BIOS but in the health status of the BIOS it claims the voltage is at 1.6. I would have chosen 1.65 in the BIOS but it jumped from 1.63 to 1.67. My luck. In cpu-z, everest, and speedfan the voltage read 1.61-1.62. I understand all of these are likely inaccurate, but it's all I got.

Must be that this board droops/drops/fluctuates. Who knows, with a DMM maybe none is true. I don't know. :shrug:

At any rate, I'm satisfied and I hope to get some better ram and take advantage of the AI7 boards robust vdimm options when I get it.

Thanks.

Oh yeah, my temps are 38-40 idle and 48 at load. I have a xp-90 but I might get one of those xp-90c's for Christmas even though they only deliver a few more in cooling power.
