Intel E8400 Wolfdale Living Review

[supershanks]

Hi Ace,
Welcome M8 Looks like the activation pigeon finally got to you, must have had a head wind

Thanks for the explanation , like i said i've altered the original ABITFAE.BAT file on my usb stick & will be running with your command line in future, much nicer behaved

Cheers

[Ace-a-Rue]

thanks...i had a heck of a time to register with all those bot questions...LOL...it took several attempts..hehehe...anyway, the tweety bird made it.

i'm baffled on why abit does not have the new bios file coded to update the boot block area...it was that way on the 1st beta bios for the IP35 Pro where the boot block was not being updated...not until i flashed the boot block did the performance increased to match my AB9 QuadGT board....AMI bioses do update the boot block as the last item of the flash...their flashing program shows that specific area being flashed.

Welcome to the forums

The good thing about all those bot questions is that it keeps us relatively spam and idiot free, with a few exceptions, notably the nappy spammer who has been 7 months pregnant for 10 years.

Might be worth adding a note to your procedure or maybe contacting abit, you think ?? Like i said it nearly did for me , the board was going into the wall until i flashed back to 11 & coincidently using your command line to manually flash.

I've a strong suspicion some of those earlier 45nm multi issues etc., may be down to this.
I'll add the command line tip to the bta bios index.

How's that dfi behaving now

Was that for me?

If so...

Yes, going good, 4140Mhz stable so far with the G0, not tried the 8400 yet until theres more of a verdict on the temps

[supershanks]

Was that for me?

no ace has one as well

I mentioned in the earlier post showing my Occt Stable that temps were a little warm , especially as i'm on water.

So i ran a little overnight experiment. Nothing radical, in fact i put everything back to stock, yep ok you heard me right
Vcore set to vid of 1.1225v.

So it primed all night small ffts to test cpu. :-
3,000 9x333 VC= 1.1225v

cleared coretemp log prior to run, so yhat i could get stats:-


Now here's one i did (much) earlier , using the Q6600 Go
8x450 @1.40v Vcore


Bear in mind this was a blend test so we need to compare the max temps over the Coretemp run for the Q6600

So we have 2x 55.5 +2x57 = 55.5 average

So boittom line on water we have :-
8400 = 46.9C Avge
Q6600 = 55.5C

Now thinkinng about Air cooling , i was able to run on air at 3.6 with the abit

Default 9x400 12HR Prime Stable Now that was about the max i would like to be on air. Looking on the 8400 there's only a 10C window between max & stock.

Are the temps right??
Not sure, there are divided opinions. It might be the temps are off.

My own feeling at the moment is that even if the temps are wrong , it would be difficult to sell on such a chip, doesn't really hack it , telling a buyer "oh ignore the temps". So will play a bit more but looking hard for an explanation/fix for these temps.

It's a sobering thought that 2 of these will go to the Yorkfield Quads. OPeople thought the Q6600 B3 ran warm

Continued .........

...well, the DFi is in the closet...LOL...it was 'ok' but i like the simplicity of the Pro board.

A great post here unclewebb on reading CPU Temps
Might give us some understanding re temps.

Update: 06/03/2008 See aslo unclewebb's Real Temp - New temp program for Intel Core processors

1) Generate CPUZ.txt File



2) Open text file , cpuz.txt you will see n blocks like this depending on the number of cores
go to reg 19C & note the DTS value, highlighted value in eax eg 3C

3) Convert to Decimal


4) Obtain Absolute Temp Deduct vakue from 3 from TjMax for your CPU, In this case TjMax = 105C
so Core Temp = 105C - 60 = 45C Now that's with my cpu at idle.

Temp = TjMax - DTS

OPtional view of Temps - Delta
Rather than look at the Absolute temperature as shown in 4) Ann alternative is to lok at the Delta or the decimal DTS.
Using this approach is rather like drivibg to a speed limit , the lower the DTS the closer you are to the limit.

Coretemp can be changed to show the Delta :-


As unclewebb says using this method

As long as you always have some headroom as reported by the DTS and your computer is stable at full Prime load then there is no reason to be too worried about your absolute temperature

In other words just check that your under the limit.

Clear

But what does it tell you about your CPU?, with regards to the high temps, are they correct?
