The Intel Penryn (45nm) Information and Discussion Thread

[soundx98]

What is the preferred program for stability testing? Orthos? Prime95v255?
Prime 95 under processes (CPU time) shows twice the real elapsed time.
Cause of the Dual cores I would imagine.
Custom 800MB for each 1G stick?

Appears to me that the latest Everest versions show the most accurate and complete temp/voltage information (and it corresponds with CoreTemp 0.96.1.)

Air-Cooled (you can call me a pansy) with the Zalman 9700 I have Core 1 running about 10 degrees hotter than Core 2.
Remount HSF or is this common to have?

Definitely all about the GTLs for me (60, 59, 60 NB) and tRFC at 36 (40 wasn't stable for me). 5-5-5-15 and almost everything else on AUTO.

4300MHz runs great but Core 1 craps out after an hour (heat probably) while Core 2 keeps chugging along for hours (aborted it after 4/8)

Ran the rig overnight for 8 hours at 4300 looping a movie.
No issues at all and very responsive.

I would bet I'll wind up at 4200MHz 24 hour stable unless I can lick the heat issue on Core 1.
I'll try and post an SS later.

So far I am really impressed by the E8400's performance.

I also think the Everest Stress is pretty nifty for monitoring temps

To those with a DFI LT LP P35 T2R, I wouldn't worry about flashing the 109 Bios at this point.
I couldn't even get into the Bios without flashing to it and the Tmod/Loggan CD did a superb job of making it easy for me.

hats off to those oldfahts

Pick up a spare Bios Chip (much cheaper than a CPU) and keep an Official Bios on it in Case of Armageddon.
Great idea to have one of the around anyway with a DFI board.
(plus a Rosary, prayer shawl, and a couple of Nuns)

Thanks for all the words of encouragement.

You have a typo in it...


Oh, while your updating that, the Sspec is SLAPL for E8400

NCspecV81, soundx98 and Tricky. Updated. Thanks the information.
Semper Fidelis. Thanks the correction.

wow. What a sick cpu. Too bad I don't have money.

Let's discuss. I have 4.23 @ 1.45v. That seems high to me, but temps @ load don't exceed 56(c). Has anyone run the E8400 @ vCore higher than that? I'm scared, but I don't know why.

(Temperature is no longer a wall!!! Hallelujah!)

Well I finally got my SLI working again so I got to run 3dMark06.

I feel the same way, its not temperature thats holding me back its the fact that Im worried about giving it too much voltage.
What does everyone think a safe voltage is for 24/7 use for the 45 nm chips, if temps are within acceptable ranges?

[linskingdom]

I would prefer to keep it under mid 1.3 as possible if you do 24/7.

FINAL UPDATE: I have two 8400 (one on an Abit IP35 Pro and one on a DFI Blood Iron. Both are running 24/7 stable at 4000; the chip on the Pro is 8 x 500 and the chip on the Blood Iron is 9 x 445. As with everyone else, temperature doesn't really seem to be a factor with these processors--only how much voltage you are willing to risk pushing through. I've decided that 4000 on both is fast enough for everyday use and longevity so the push for the max has come to it's conclusion.
Here is what I learned along the way:
-the Overclock.net community is smarter than I ever will be.
-vdroop can really affect the way a mobo overclocks.
-I need to pay attention to the BIOS voltage readings.
-I didn't need to increase my VTT on the Blood Iron for stability.
-G.Skill HK and HZ overclock almost the same.
-the same chips can have very different characteristics.
-even after reading about it, I still don't know what GTLREF does!
-every time I got stuck, linskingdom was THE MAN!!
Thanks to everybody that posted their own results and good luck with your little slice of the overclock pie!
