dark22: may i steal your cpu?

the problem is that on that frequency my temps are very high!!!
79C i thing is to much for that cpu...
i also tried at 4.5Ghz with 1.4 but is not stable, i thing because of temps...
i saw 90C and i dont feel comfotable with that...
until now i havent change GTL settings but i think that i will need to
and also better cooling because here in Creta the weather is hot...

mine don t have temps issues but isnt stable 4.5 ghz with 1.40 v anyway.... (I THINK EVER TO NORTH POLE ISNT STABLE by those vcore) it does 24 min orthos at 4.283 ghz with 1.376 v(6 min it did at 4.33 ghz LOL) i didnt change gtl setting too...i think ur is so hot because have lower VID than mine

**dark22** · 03-01-2008, 04:02 AM

i went out and i left it for a little longer...
i think at ~4400 Ghz it can be stable with 1.39-1.4...
about the temps probably coretemp it is not reading well...
i am waiting for real temp... to test again...

**kathman** · 03-01-2008, 04:03 AM

Hi everyone =D.

I went for 4, but I couldn't get it stable, so I'm going to give it another try tomorow =D

yes coretemp and all the software not reading correct...but 81 anyway i think is real hot...i think 4.5 will be stable at least at 1.44-1.45(i mean 500x9 not 490x9)...mine after 11 hr show 66 C core 0 and 62 core 1

Get everest, it reads Wolfdale chips correctly. Atleast on mine.

**hersounds** · 03-01-2008, 11:06 AM

i agree the last everest read very well my 8400
when overclock i just look everest to see all right ( or not)

**CrazyNutz** · 03-01-2008, 11:39 AM

I've been doing some research on the temp confusion we all seem to be having with the wolfdales. Coretemp thinks the Tjunction max should be 105c
but from what Im finding from reading the Intel e8000 datasheet Tjmax should be 92.4c, this calculation is based on Tcase max of 72.4c + Ttrip of
20c over Tcase which = Tjmax of 92.4c

Just thought I should put this out there.

**dark22** · 03-01-2008, 11:57 AM

my everest 4.20 reads the same like coretemp...

**hersounds** · 03-01-2008, 12:00 PM

Everest Ultimate Edition v4.20.1292 Beta Multilenguaje

read very fine my 8400, no troubles.

[/url]

it is not reading correct because with everything stock at idle says 43-44 which i believe is imposible...

**Spyrus** · 03-01-2008, 12:15 PM

Man my first opinion 1.45@4650 is close enough.
I like that you love your cpu (φτου μην τον ματιάξω)
Are you on air? Mine does 4500@1.45 all benches but orthos tested only for 24/7 setup 4050@1.3V
which is a good cpu amongst others just think that for your cpu how excellent it is. It reminds me of
my previous E6750@1.3@3.6 on air.

**Xvys** · 03-01-2008, 12:34 PM

My Everest Ultimate and CPUID Hardware Monitor both show my idle cpu temp at 28C @ 4.1GHz, while in the bios the cpu temp is 32C? I would probably believe the latter, and add 4C onto the Windows temps.

Some other posters have confirmed that thermal throttling starts at bout 95C, which would bring the tjMAX of 105C into question. I guess we could then add 10C to the core temp readings in Windows, also.

**Furiøùs** · 03-01-2008, 12:54 PM

... When your in BIOS the CPU is under load... fail

Not a very high load, but enough to bring the temps up 4-8 degrees.

that would be - 10c not +

**alcatraroz** · 03-01-2008, 02:03 PM

everest ultimate latest version beta read the same temps of coretemp..isnt correct IMHO

I combined it all, somehow, along with my experiences with pointing an IR thermometer at my bare E6400 and E8400 CPUs and have created a new program called Real Temp. The swiss army knife of temp software.

I finished the data logging feature tonight and after I write a pile of documentation for it, it will be ready for download tomorrow.

Will you be posting Real Temp here? I have been following your comments throughout this thread and am very interested and anxiously waiting.

**dark22** · 03-01-2008, 03:12 PM

thx Spyrus

i have some issues with my mobo P5k Green... it is degraded...
i cannot be stable at 500 fsb... crap...
I also cannot give more than 1.5 volt on the northbridge... when i put more no boot...
so i am trying at 4410 mhz with 1.37-1.38 but i cannot make it stable...
the same issues i have also at 4000 mhz... it is not stable know...
but at 445x9 it runs at the same volts... 1.2...
so until i will find a desend mobo i cannot search for higher stable frequency...

What's the best budget board for E8400 overclocking? I don't need RAID, or SLI, and will be using a Tuniq Tower heatsink.

**g0dM@n** · 03-01-2008, 05:16 PM

If anyone has figured it out, I'd love to know what GTL REF voltages work best with what VTT... like maybe a list or something.

It's taking me forever to figure it out, but for me with 1.12vtt I was getting similar results with 59, 60, and 70... as long as it wasn't set to default b/c default was the worst by FAR.

I just post'd at Overclockers about this, but I have found with my board, that 63/63/67 works best for me.

**maxwolfie** · 03-01-2008, 06:56 PM

How do I adjust GTL/ VTT etc on my board? There's no option (Giga P35-S3)

Can I do it via software in windows?

I'd love to get the GTLs figured out myself. I'm just having a heck of time trying to get much over 500 fsb out of my setup. It could be the board I suppose.

Anyway, decided to play with the small ffts today. Much tougher to get it to run. This is the best I could do at 1.36 vcore. Funny thing is just one more on the fsb and it wouldn't go more than 30 sec. I'll try playing with it more later.
