3.2E Overclocking results

[AristoV300]

I got my 3.2E to run at 3.8 on stock vcore. It is completely stable after I ran all of the stress tests through it. What do you all think is a reasonable vcore for a D0 Prescott for everyday use. I really want to hit 4Ghz.

 

[Corporate Thug]

WOW, very promising start. how long did you prime it for?

i wouldnt give it any more than 1.65V

 

[AristoV300]

Over 6 hours along with Sandra Burn In, 3d Mark 05, and Aquamark.

 

[Lithan]

Nice one. I'd say try and keep it under 1.55v

 

[AristoV300]

Thx. I'll see if I can get it any higher stable with a vcore bump.

 

[Adn4n]

Ditto on the 1.55

Try and Prime it for a day.

 

[Soulkeeper]

yeah anything higher than 1.55 seems excessive
i keep my 2.8e at 1.36v till i get to about 3.3ghz then i up it to 1.47v to 1.51v for that extra 100mhz or so
anymore voltage doesn't really do anything

Is your computer on fire? :laugh:

You know you can't do that with a Prescott, right?

 

[AristoV300]

My temps are the same as my old northwood. 38 Idle, 45 load with xp-90 and 92mm fan at 3000rpm. D0 stepping runs pretty cool.

Yeah I agree, I tried and I can get a little more out but it is not worth it. The high vcore is just going to fry the chip in the long run. I think I'll stay at 3.8 with stock vcore.

Well looks great to me if you are telling truth.

prescotts are hot, but not that hot, lol. the overclock does seem pretty unreal, especially if done on air. i 0n0, its still a great overclock. why not try to oc to 4ghz if intel isnt coming out with one? :laugh:

No reason to lie. Here is a CPU-Z screenie.

[hytek369]

wow, nice chip, where did you get yours from?

 

[AristoV300]

I hand picked here in Japan from a local shop so I could get a D0 Stepping. 6/3/2004 Pack Date from Malaysia.

 

[ntrights]

Very Nice temps !! Stay below 1.5 with the vcore if you want the chip to last for a long time. D0's seems to run about 5-10 cooler then the older C0 stepping...Im planning to get watercooling for 24/7 stability at 4 ghz (got a c0) ...right now im at 3.924 (14x280fsb)...

 

[AristoV300]

Yeah the C0's run warmer but you have access to the 14x multi with the 1018 BIOS, I don't:| I was hoping to put this PC-4400 to good use to run 1:1. I am curious to see if the E0 will be able to go to 14x...

 

[ntrights]

The 14 multi is nice...but hey you got great temps and you can probably get it to 4ghz+ STABLE with air!?! Have you tryed going higher? E0 with 14 multi would be great, less heat and the 14 multi!!!!

 

[AristoV300]

Yeah I can get to 4.1 @ 1.525 in windows but I am more comfortable with running it at 3.8. I would like to keep this chip and not fry for a another 200mhz. The XP-90 is great HS though.

 

[Soulkeeper]

`nice to see a few more crazy prescott overclockers around here

I find that prime95 does well to test cpu stability at load temperature (improving temps often improves prime95 stability). Sandra Burn arguably does nothing. 3dmark is great for testing cpu stability at a given voltage (upping voltage usually fixes crashes during cpu tests). Aquamark only tells you if your system is VERY VERY VERY unstable. I also include in my tests UT2K4. I'll often play 2 complete deathmatch rounds with 6 bots at maximum settings at 1024. This has been, for me, the most demanding standard and most telling of system instability, no matter how stable it might seem by other tests. Neither increased voltage nor lowered temps help. Only a lowering of the FSB does.
