Panzer_V you need to run two instances of Prime95 for dual core for over 4 hours here is a good tutorial:

Hey, not sure if I'm ready to post this yet since I'm planning on improving it more. But I got fed up with the ds3 and my buffalo blew up, so here's a new screenshot I did:



It's 8x425=3400 e6400 es 5b1 l617 a856 1.4v actual water swiftech apogee p5b vanilla 1102 bios

win2k3 again. ocz 8800 this time. 1:1 425mhz (850) 4-4-4-4 4-20-3-9-4-10 (memset shown just for reference but actual values set in bios).

2.29v actual vdimm.

1.25vmch, 1.2vfsb, 1.5vpcie, 1.057vich


large fft orthos 16 hours (been longer but never screenshotted)



Currently, I'm unable to go much beyond 450fsb, so I had to settle at 8x425 with the weaker strap performance. I hope to look into actual vmch values and hopefully be able to run 7x485=3400 or better.

ram ic is d9gmh

yes you are right thought about it for awhile was gonna make the change but never got to it...... mentok1982 probably didnt know that it was the same company... real name is

sunbeam tuniq tower 120.... thanks for your concern
 
Ok
I give up on how to identify the stepping my chip is
SL9S8
L639F039 so far in the database that Kyle is keeping there isn't any e6600's
with code F039

SO someone give me a clue :p
LOL

Is there any way to find out that Week and code other that disassembling my PC? Btw. This was my first oc :D

Yes, if you kept the original CPU box. The info is written on a label and match the writings on the CPU.

My first try at 3520 MHz was stable for 10 hours but unfortunately Windows adjusted the system clock by 3 seconds during the run so it looks a little suspicious.



Hopefully this second run is enough to get me into the [H] OC database as one of the quickest Intel cooled E6400 chips.

hahaha your funny rats.... well we will see how long this chip will last... i live on a tropical island it burns everyday... coldest it ever got one night was 73*F haha... maybe ill invest in an A/C unit for my computer room....but dont want to spend alot on power :(

Will repost screenshot after 24 hours hopefully.
This is an update to my earlier listing of 8x425=3400 on the p5b vanilla.

I've found that enabling spread spectrum allows my p5b vanilla to go from 460fsb max to around 520fsb. Unfortunately, performance isn't spectucular, due to 1333strap.

This listing is not fully tuned and tweaked in terms of memory timings and voltages. It was an initial attempt at 7x500=3500 stability, but should update the existing 8x425 entry well, and does prove the point of the c2d's overclock.

It should also be noted that there's something wrong with my apogee waterblock and temps I've been seeing recently are way higher than when I initially started using the block in January. I used to be able to run 1.55vcore and still keep under 60'c under full load.

I did run orthos along with 3dm2k3 last night for 10 hours, but since it was a custom test (8-1024 in place, 5 minutes), I didn't bother screenshotting. Currently, this is large fft that is about 4.5 hours already, and shows no signs of instability.

edit: It is a different cpu than in the previous listing, but I hope to sell that one soon. Surprisingly, both cpu's have had nearly flat IHS's and similar temperatures under the same conditions.

update: 16 hours and going


update: I was still sleeping when it hit 24 hours. When I woke up, the screen was blank (from power saving) but system was locked up. Reset does nothing. Had to cut power from back. It came back at 7x500. I got fed up and tore the motherboard out and alcohol washed the entire motherboard. Looks like now it's doing 500fsb without spread spectrum, although it sometimes won't post. I'm working on that, but it's definitely an improvement over before, when I needed spread spectrum to post 500fsb.

I tried low voltages (mch, sb, ich, fsb) and it locked up in the same fashion really quickly. So I'm imagining the lockup I had last night (I checked orthos log and it looks like it locked up after 26 hours) was due to motherboard issue.

edit: damn, looks like 500fsb is no more. I can't maintain it stably anymore at all. I'm pretty sure the cpu is stable though, but I guess hold off for now. I'm testing 7x438=3066 right now with everything relaxed to make sure 438 is stable, so I can prove 3.5 first. Can't wait for dfi to come out...

This is my buddy's E6300, the batch # is L28 but the rest is unknown cos this cpu was lapped.... It was watercooled using Swiftech mcw5000 waterblock and Bix 3 radiator with 3 120mm 121cfm fans ....

New E6600 CPU, L644F262.... getting later in the production year, 44th week.

So far, 3GHz (9*333MHz) Orthos stable for 4 hours @ 1.375 Vcore.

I'm pretty happy with the ease of getting to 3GHz, and hopefully looking to get 3.6GHz later this week. Seems the "F" code CPUs are nothing to be scared of, thankfully.

(Not looking for database entry yet, more of a info post for people looking for F-code CPU info, feel free to nuke this post if warranted)

When using Orthos it says I'm runing 400 Mhz faster than I am.
Anyone have a solution to this?
When testing at 3.2 it reports 3.6
