E6400 overclock - I'd say it's stable after 24 hours :)

These C2D chips really are amazing. Here's a screenie after almost 24 hours of dual Orthos. The room temp is 19.6C; roughly 67F.

I hope that everyone can see this screenie...I never have gotten the hang of full Desktop screen shots. 😱

For those who can't, I'm at 3.20GHz (8 x 400) @ 1.320v in the BIOS (1.296-1.312 according to CPU-Z). Load temps (as measured by Intel TAT) are 57C.

Note the discrepancy in temps b/t TAT and the Gigabyte EasyTune utility. At idle, the gap is even bigger; usually 14-15C.

Here are my relevant specs:

Gigabyte DS3 MB-F7 bios (CPU-Z shows F4, but it's wrong)
E6400 (L629A728 stepping code on the CPU)
2GB (2 x 1GB Corsair PC6400 ram) The CAS5 stuff...not the $$$ CAS4 stuff. All AUTO timings on the ram.
AC Freezer 7 Pro w/AS5 (fan control set on Auto in BIOS)
Antec Trupower 2.0 550
Antec P180 case with stock fans in stock positions all at low speed
EVGA 7900GTO (not OC'd yet)

PIC OF SYS INTERNALS

I ran 18 hours of dual P95 before this test and called it stable...but then I read that Orthos is supposed to be the new "Defacto" ocing stability tester. To me, it just looks like a pretty way to run dual P95 loops. 😛 But hey, I played along. 😀 I'd say it's stable.

Just wanted to share my OC goodness! :beer:

I've been told I should push for more, even at this voltage. I also know that the ceiling for these chips on air is 3.4GHz. For another 200MHz, it's not worth it to me. This thing is already faster than my old dual Xeon @ 2.6GHz and plain smokes anything else I compare it to. I'm happy.

It is not a discrepancy....It is clear they are not reading the same thing....We have never been lead to believe the temps reported by mobo manfacturers has been a digital temp taken deep within the core...

You're technically right, Duvie. But it would be nice if the mobo manuf's would stop reporting "CPU temp" in their reporting utilities. It really is misleading.

Very nice, especially since your vcore is lower than stock max 🙂

I agree but they are reporting temps most in line with what manufacturers of HSF are designing to...The temp at the underside of the IHS....That is the temp the HSF needs to disipate....

Thanks, N7.

I wonder what will happen to my temps once summer rolls around and the room temp goes to say, 28C. :Q

I may have to crank up the case fan(s) at that time. I am loving the QUIET the P180 gives me. 🙂

This C2D chip is "it", man. 50% overclock, with minimal fiddling? Heh, I remember when you'd have to do the pencil trick, plus move some jumpers, wave a dead chicken counterclockwise on the SECOND Tuesday of the month just to get 100MHz extra out of a chip. These are good times! :beer:

Actually, the E6300 is it 😉

75-85% OCs are the norm with it, but good RAM is needed (or just a good knowledge of which RAM OCs to 1000 w/o trouble 🙂)

LMAO!!!

right my fist OC was a 400mhz K6-2 I was able to get 33mhz out of....or 8% OC

my next was a 750 tbird I got 840 out of or about 14%

Then my beautiful 1.6a@2.7ghz or 69+%

Now I have a 1.86ghz@3.43ghz or 84%
