Got it to 3.7Ghz @ 31C But i didn't like the votlage i had to give it (1.6V) So i backed it down to 3.433@1.5V New NB cooler will be here Wednesday i will do some more playing around with it. Anyone else got better E4300 OC?

the processor temp on Gigabyte P965 based has been adjusted for a more accurate reading after BIOS versions that has already added support for new super IO version, likes BIOS F10 for 965P-DS4 and F11 for 965P-DQ6, otherwise, the processor's temp will be too low. if you have not using the version of BIOS with your board, then for checking processor's temp try using Core Temp or TAT instead.

1.5V is quite a bit of voltage for air. Is that Orthos stable at all?

1,5, that would be max for air IMO and yeah check out temps in Core Temp while running orthos. I'm guessing it's hitting the 70's, which is fine also, but dont let it get near 80.

Well i ran Core tem while it was @ 3.42 *Orthos was stable* And it reached 61C once then dropped down to about 58C the rest of the testing.

Im happy with it @ 3.33Ghz Super pi is 17 seconds @1.325 V Idle 24C load 41-45C (With Core Temp)

Its crazy that it needs so much more voltage to go those few more MHZ. 3.33 is the happy spot with this chip

3.33GHz is pretty decent for that voltage. Beats my E6600 for low volts.

Just a minor question on the side....have any of you guys heard of an C2D that actually have been killed due to too much heat/Voltage...? The reason I ask is just because that I can't recollect anyone stating to have killed their C2d at all ....?

Can't say I have...

For that matter, I don't think I've heard of Athlon 64's being killed directly from vcore either, only from excess DRAM voltage.

Even if I'm missing any, I think that the amount of voltage required to quickly fry a CPU are far past amounts which will stop yielding much benefit in clocking.
Theoretically, higher voltages on the same chip will yield a lower lifespan, but it's rather difficult to test, as in either case, the lifespan is measured in years.

I love this chip. i havent seen anywhere online selling it anymore tho? Ah oh well when im done with it ill go quad. This is plenty of power for me ATM. beats the x6800 in some benchmarks

good processor overclock result ,
however, i think the 31C on your first post was not right. so you may want to remember using the Core Temp or TAT to check the processor's temp,

and for your information, this is different in the case of using C2D E6750 GO, the CPU Core's temp does not seem to be an accurate reading by any Core's temp reading programs yet.
the processor's temp from EasyTune5 (for Gigabyte P35 based) seem to be more realistic at this time.


---------------------


yea i think i will never considering running my 24/7 system with an extreme high voltages. however, i've been often using 1.55-1.57V Vcore on B2/L2 C2D's on air, for hours and hours, yes, but never running 24/7 with something above 1.475V or so. i don't have nor have tested with a lot of C2D's, but with what i got, i've not yet killed a C2D processor with mentioned Vcore.

memory modules are quite different, some are easily just dying or went completely dead, suddenly. and it's not because of too much Vdimm either. sometimes, when the memory froze the system up, like during memtesting, and this could be, in some cases, because, not too much actually, but not enough voltages, either MCH, Vcore and the Vdimm itself.
and the memory modules could be killed if you shutdown the system by holding down the case's power button.

Lowfat

I've yet to see any C2D die that wasn't caused by condensation from under phase, or someone trashing it by pulling the heatspreader.

But 1.5V on aircooling is a lot of heat, even my Tuniq Tower couldn't keep my old E6400 at that temp without it jumping in the high 60s.

nice overclock? what's the stepping (if you know offhand)?

A friend of mine has the same chip as you on water, and he hits 3.9ghz, obviously on air he was maxing around the same as you as he didn't want to kill it with voltage/temps.

Might be a worthwhile investment at some stage going to a decent water cooled setup...

PangingJr

AFAIK, E4300 1.80 GHz is "L2", i don't think it is not yet available in "M0",
E4400 2 GHz has both L2 and M0,
E4500 2.20 GHz is now M0,
all are C2D 2MB processors.

josh2thad

Yes it has the L2 Stepping, Was thinking about water cooling... HMmm

Erroneus

Whats the highest FSB you had the cpu at, because there is a FSB strap on them, in some motherboards.
