e6400 OC, proof you should go conroe

Temps are still the same after a full half hour. Bios voltage is set to 1.35

This seems like a pretty good temperature, considering its similar to idle temps at stock speeds with a stock fan (at least with my testing).

I'd go higher, but my ram is only 400mhz. I could overlock that too, I'm sure... but I'm not going to do that until my system starts actually running at full load once in a while outside of a stress-test.

thank you for sharing your overclock... but just because you get 3.2 on a 6400 isn't "proof" you should go conroe/allendale.

there are many that have an 939 setup that is perfectly fine for what they need to do.

yes, the conroes overclock very well but that is not reason enough for people to "go conroe"

Those temperatures are a bit hard to believe...Orthos @ 43 degrees w/ stock cooler?!?!

 

[Stumps]

meh, I'm happy with my OC'ed A64 skt 754 setup...no need to upgrade just yet.

 

[melchoir55]

Oh, sorry, you misunderstood. I started by testing temperatures at stock speeds with a stock cooler. Then I removed the stock cooler, re-applied the grease and put on my aftermarket heatsink. Then I oc'd it to 3200 and checked temps. At 3.2ghz under full orthos load it's running about the same temp as it was idling at stock speed with a stock fan.

I'm pretty confident this could go higher than 3.2, but I don't want to screw around with my RAM to do it. 3.2 is enough for me.. for now.

pretty decent oc compared to others i've seen, but nice none the less, i my self am aiming for 3.4

I can't get 3.4 stable I am at 3280 right now. I am also using DDR2-667 Ram though but it's crucial 10th anniversary but I had that up to ddr2-1000 5-5-5-12 when running a FSB of 400 for 3200. I dropped it down to a 2x multiplier on the ram and raised my FSB to 425 for a 3400 even but it wouldn't be stable in orthos after 5 minutes. It was completely stable in real world and games though oddly enough. I had the voltage up to 1.4 vcore evenat 3400 and it would not take and I didn't like the temps at that voltage so I am down to 3280 on more reasonable voltage =(.

Oh I have a P5B-DlX and the E6400 too.

 

[melchoir55]

It's possible you are simply reaching the limits of that particular cpu?

1.4 seems like alot for a 425 fsb, I'm stable at 1.35 with a 400. Of course I don't know how much juice you need to start pushing in past 400. TBH I think 3.2 dual core is more than enough right now.

I have heard ppl having issues getting that board past 420fsb withoutr the right bios, settings, and some luck....

1.4V is like 1.35-1.36V with vdroop, which is rarely enough to get you to 3.4 GHz Orthos stable.

You'll need around 1.45 (1.40-1.42V w/ vdroop) to be Orthos stable @ 3400 MHz.

Also, i've recently discovered the last four RAM sub-timings on P5Bs often default too tightly.
Might help using something like:
x-x-x-x-6-42-5-11-7-14

Instead of normal x-x-x-x-6-42-10-10-10-10

:shocked:

I don't know of a single instance where the P5B-D can't do way over 420 Mhz FSB (unless user has crap RAM).

P5B vanilla is a whole other issue though.

E6400 @ 3.3GHz, 1.343Vcore, +0.1MCH and +0.1FSB.
Gotta love the Kingston Value DDR2-667 sticks, easy OC at +0.1V (1.9V).

I'm loving my Conroe.

My voltage is set to 1.275 in bios. It droops to 1.264 (flops back and forth between 1.264 and 1.248, but spends more time at 1.264)


I've noticed when running orthos, the temps hit their max around the end of the first hour, then drop a few degrees and become stable after that.

NOICE! That's almost identical to my setup. My north bridge cooler comes in tomorrow which will hopefully get me up to 3.4. Right now I can push 3.2 with stock voltage.

I don't see that as "proof" to go C2D really. My opty @ 2.81GHz (not even pushed hard, still stock volts) is fine for all I do, no need to spend all that extra $$$ for a new CPU, mobo, and RAM for those extra 3Dmarks or 1 or 2 FPS in games. No money to upgrade a darn thing anyway

And 30 minutes isn't what I call tested fully stable. I don't doubt that it can be stable at that speed, but I've seen CPU's fail orthos runs a couple hours in (my old 3700+ comes to mind with SP2004).

Use large FFT testing for Orthos and see what your temps are at full load after 30mins.
