I've spent the last two days trying to select the best tweaks for Super PI. In fact, benching Super PI with C2D is very different than with A64. I was quite confident with my good old tweaks but I must confess that I'm a noob now for tweaking Super PI while running a C2D.<br>
The CPU was cooled by an homemade watercooling system and only needed 1.4Vcore to operate within @3600MHz to 3680MHz.<br><br><span style="color:#FF0000;"><b>Normal mode with Olive Green color scheme (Tweaks: modified registery keys + Maxmem=600): best run achieved in 13.797s</b></span><br><br><img alt="" src="http://img87.imageshack.us/img87/3268/e6700spi1m13797skz6.png" style="border:0px solid;"><br><br><b><span style="color:#FF0000;">Normal mode (Tweaks: modified registery keys + No page file + Maxmem=600 + Copywaza=1.6Gb): single run achieved in 14m 37.844s</span></b><br><br><img alt="" src="http://img401.imageshack.us/img401/9128/e6700spi32m14m37844nf8.png" style="border:0px solid;"><br><br><span style="color:#FF0000;">-----------------------------------------------------<br>

But today I've put the bad baby under 2-Stager to begin serious things... My motherboard is fully volt-modded but I didn't tune the Vmod trimmers yet and only set voltage settings to the max instead of the CPU which vcore has been set to 1.60V 'only'.<br><br>
Take a look a the temp <img alt="" class="inlineimg" src="/images/smilies/cool.gif" style="border:0px solid;" title="Cool"><br><br><img alt="" src="http://beforeoverclock.com/images/P1020088%20copie.png" style="border:0px solid;"><br><br><span style="color:#FF0000;"><b>Normal mode with Olive Green color scheme (Tweaks: modified registery keys + Maxmem=600): best run achieved in 10.703s</b></span><br><br><img alt="" src="http://img134.imageshack.us/img134/7845/e6700es4780spi1mnq2.jpg" style="border:0px solid;"><br><br><a href="http://valid.x86-secret.com/show_oc?id=132820" target="_blank">http://valid.x86-secret.com/show_oc?id=132820</a><br><br>
I've to find more useful tweaks but the next step is to overclock a little bit more... <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin"></td>

Any reason for an IDE HD instead of a SATA HD?

Thank you so much guys! <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile"><br><br>
@wowza: actually, I don't know if it exists a real difference between overclocking with an IDE HDD than overclocking with a SATA HDD. May be...<br>
BTW my 320Gb SATA is already used by my desktop computer so I've to bench with my old IDE.

SATA drives can cause instability at higher FSB and PCIE frequencies<br><br>
For example (not a great one though) my 805 can do 195x20 with a SATA drive and PCIE at 105, but can do 211x20 with an IDE drive and PCIE at 114.<br><br>
Pratical for everyday use? Probably not, but if your sole goal is to find max stable speed, and IDE drive is a must or a PCI SATA controller.

</div>Or a motherboard with separately adjustable PCI-E and SATA frequencies (which I think newer boards should have - I know mine does)

I think the record was 8.9 seconds or something.

Thx guys <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
@Mazeppa: TweakGuides is a very nice place <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /><br />
<br />
@Whodie: interesting! Thx for sharing.<br />
<br />
@OzziKing: actual Spi1M WR holder is my friend OnePageBook-san with 8.906s<br />
<br />
@Kopi: actual highest operating freq. for a 6700 is 5140MHz<br />
<br />
Be sure that I'll try my luck at 5GHz and above <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" />
