DI-party in Warsaw, PCLab.pl involved :), E4400 & Cel420 WRs :D, QX6850 @ 4,86GHz
Hello!
Last weekend we had a DI-party* in Warsaw: , including a "session" with E6750 ES in the PCLab.pl headquarters :).
*my first-ever DI and second subzero - the first was with piotres's cascade - http://www.xtremesystems.org/forums/...d.php?t=142898, the results {not great for an E6700 L629B, time and VCore limited} http://www.xtremesystems.org/forums/showpost.php?p=2172518&postcount=54}
Hardware:
Asus Commando + VDroop [pencil] {"both"} by JMKS
VGA 8600GTS by PCLab.pl, 8500GT DDR3 by jumson, Gf6600 by JMKS {no graphic benches :p:}
PSU Silverstone 850W by PCLab.pl + ModeCom MC500 by JMKS
RAM Corsair Dominator 10000 by PCLab.pl + GoodRAM PRO by JMKS
CPU's: E4400 by jumson, E6750 by PCLab.pl {or by Intel, I don't know what to write ;)}, E6400 by JMKS & Cel420, I don't now who is the owner of this (me or my friend takero, we must decide afterwards ;))
Thermal grease Arctic Ceramique (thx Team Japan for the "tip" :))
DI container by piotres

E6400 "1333 FSB mod" - unfortunately it isn't working at all (CPU is working but 266 FSB standard, nothing else) - maybe the "graphite ink" used was not that special, hmm...

after the tests with E4400, WR done! {easily :)}
and the best:

shortly after the benches, the view from my windows - as You can see the sun is shining - I started this "session" shortly before midnight and tha photo was taken at 4:36 AM, I'm sleepy... ;)
czyli widok z okna tuż po zakończeniu benchów - jeśli wierzyć komórce, to zdjęcie zrobione o 4:36 AM - coś wcześnie / późno (zależy jak patrzeć ;)), w każdym razie zważywszy na to, że 2 dni wcześniej miałem 36-godzinną dobę to będę to musiał niedługo odespać :]

After the session with Cel420 {another WR ;)}, some freezing action {the PC isn't running of course}

After all the tests. In this picture You can see the homemade heatsinks for MOSFET cooling :)
OK, let's talk about the results ;):
First test was with E6750. It is great CPU for daily use, 4GHz fully stable possible with ~1,4V I believe :woot:. Air pretesting gave me some good results - 4080MHz 1M with 1,55V (lower not used ;)) and SetFSB to 515 FSB => freez.
Under DI the FSB-wall was absolutely frustrating - highest benchable FSB was 520 which gives 4160MHz "only". BTW, "strap modification" was used {thanks to jp @ ixtremtek.com I must say ;)}- no genuine 520 with air cooled NB and my Commando possible.

Max validation: http://valid.x86-secret.com/show_oc?id=213054

4GHz {pseudo, only 15mins but who is doing Orthos under DI?!}-stable with 1,35V - I don't know if it is great or "only" very good :).

Now E4400, really sweeeeet :):
Max air, 1,70V, 4090MHz

Picture of the air setup (it's my 24/7 setup :D, of course except of CPU, and VGA):

Max 1M 4010MHz 13,89s - if someone's interested: http://hwbot.org/signature.img?iid=25007&thumb=false
Now let's cool it "a little" :):
all results with 1,7625V @ BIOS => 1,808V idle in BIOS, slightly higher under load I think - the result of the VDroop :)
FSB Termination 1,45V
NB VCore 1,75V or so - with HR-05 this NB survived 1,95V for a lot more than "couple" of hours :), 1066 strap in all the results of course
max MHz - 4710MHz - WR by more than 200MHz I believe :D
FSB-wall limited maybe, 475x6 => no POST, FSB-wall on air ~440
http://valid.x86-secret.com/cache/213661.png
http://valid.x86-secret.com/show_oc?id=213661
max 1M - 4620MHz - 12,375s - not bad for an Allendale IMHO :)
http://img441.imageshack.us/img441/7919/1m462ghzcr3.jpg
16M "Polish national bench" {but not maxed, You will see ;)}, 4,53GHz
http://img224.imageshack.us/img224/7...m453ghzwm9.jpg
32M with higher frequency than 16M :), 4,54GHz
http://img441.imageshack.us/img441/6...m454ghzge9.jpg
The clock on the screen is working correct, yep, it was close to 4AM :)
And a big disappointment - PiFast wasn't stable even with 4,4GHz - WTF?! :( 4,35GHz finally:

The end of the E4400 benching and I could not resist, once more:
short after the bench ends
http://img441.imageshack.us/img441/4116/dsc00590nm5.jpg
The next day and the new CPUs to test :):
Celeron 420 with hmm... 1,45V {overkill! :p:, stable with 3,2GHz and 1,35V on air}
On air the FSB wall even for validation is ~425.
max MHz: 3552MHz - WR (temporary ;))

In the PCLab.pl headquarters I also had chance to bench WPrime on the dual Clovertown machine :) - 7,66s 32m and 3m44,98s in 1024m.
More photos to come! I hope You like this :).
Enjoy!
{PS. It seems that I must polish this in some places because the photos etc isn't showing correctly - give me a moment and it will be OK - that's the result of using notepad for writing ;)}
