Wow temperatures are rising in here!

I am sure there was just a language/translation problem, no need to take it personally guys, we are all here doing the same thing.

[Grnfinger]

I think your system is capable of more than that; I'm getting better 32M times on my untweaked regular OS (Vista) with only 4.3Ghz @ 8.5 x 506. Keep pushing

Would you care to share that 8.5x506 setting?

I have 4.3GHz on the 9 multi but would like to test the 8.5 for the hell of it and maybe better bandwidth

nice going it seems the e8400/8500 likes the p5k motherboard as cordovader who posted earlier also had good results , whats the fpo/batch code of your chip

What's your max fsb with the p5k deluxe ? Can you try 7x multi (like 7x560-570 580... )and Can you give me a bios settings ?

[HaTaX]

Well, I went back to the store and exchanged my CPU for another one, Q746A503 is my # and it seems to be much better...
4014mhz @ 1.27v VS 4014mhz @ 1.44v running orthos on it now and it has made it past the 10 minute mark. I'll be curious to see where I can get with this chip.

I want to run it around the 4ghz mark 24/7 so this seems to be much more suitable.

[Merc14]

My 8400 is:
Q746A377
1.225v
Pack date 1/4/08

I couldn't get her to 560. Maybe 540. I'll post some settings later have to watch the ball game.

what bios u are using on the P5K Deluxe?

[maxwolfie]

People are saying ignore coretemps and look at CPU temp, what program can be used? (Most accurate?)

[flesheatinvirus]

Here is my 1meg Pi at 4860mhz.

0705 Works great.

@ flesheatinvirus
Nice clocks there. Your RAM is doing some pretty good clocks there,congrats !

[Merc14]

Here is my 1meg Pi at 4860mhz.

@frzzy and flesheatinvirus
I don't understand how I could get a 09.891s time at 4682MHz and you guys are getting just 09.578s at an incredible 4860MHz. You both should be in the 8 second bracket i would think. What version of Spi are you running? I have noticed that I have to run Pi twice to get a good number. The first is always higher. I have no idea why. Incredible clocks BTW guys, very well done.

It's just normal on intels.

A quick test with my E8400:

[Merc14]

I guess I have to up my volts. Great job guys. I can't believe we can get in the 9 seconds on water. Never thought i'd see it from an X86. An amazing chip for sure.

*cough*

[Xvys]

Maxwolfie: CPUID Hardware Monitor and SpeedFan are two free programs which show the cpu temp in Windows, although SpeedFan seems a bit buggy with the Wolfdales.

I was wondering why I can't break the 10 sec. barrier in SuperPi1M. I have the same or better settings that some of the others, but 10.2 sec is the best I can do? More FSB?? Some have broke 10 sec. with 502FSB with the same ram timings as mine? Is it my crummy DDR2-667 ram or do I need water cooling??

Thanks mate!


Could I use CPUID for all voltage and temperature monitoring? Is the rest of the reporting accurate? I'm finding that I have about 10 programs that I need lately :|

[Retrolock]

wow, a lot of 1.6v out here lol... i hope our suicide runs dont massacre our procs, mobos and mems lol. The max I did was 1.55v (1.536v vdroop) for my 4.5ghz run.

[scottc19]

So just so we are all on the same page. It is confirmed that the core temps are not working... Mine is idling at 34 C and core 1 says 60C and core 2 says 43. Also the two cores dont flucuate much. Ive tried reseating my water block 4 times. Changed thermal paste twice. And even flipped the water block around. Made no differnece at all and did not help lower the gap between the two core temps. So I am pretty sure that these are not worth looking at, which it seems the rest of this thread is in agreement with. I just wanted to make sure.

I've started trying to overclock this with the 680i and am having a hell of a time. It seems I have a fsb hole. At 1800 it wont post no matter the multiplier. At 1900 I can run orthos, but seems to be freezing after 2-8 minutes. I am going to do more tests, but this is as far as I got with day 1. Anyone else have any luck with the 680i.

For those concerned with high voltages and degredation here is a link to the E8000 series data sheet. Section 2 covers electrical specifications. ftp://download.intel.com/design/proc...s/31873201.pdf

[mrcape]

There's also a supplementary document / spec update with a list of errata.

Many of the errors mention workarounds that can be addressed in updates to bioses. Others will be addressed in a new stepping.

Pain in the butt for board and bios engineers, but would be very grateful if they did the fixes that they can.

This is not a job of bios engineers. Microcode update is supplied by Intel (usually before the chips entering the market). By the way, C2D 65nm. has a bit longer errata list.

Well the microcode update would have to be added into the bios and new bios prepared and released no? I do remember there being a bunch of issues with 65nm C2D and I think there was a microcode update for those.

If you look at the list of errata there are a lot of "bios workaround" mentions. For example the most recent addition - AW51 from 02/01/2008.
