Hello OCN <img alt="smile.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/smile.gif"><br><br>
This will be my first attempt in extreme cooling.<br>
After failing to achieve 5GHz on water...<br><div class="bbcode_center" style="text-align:center;"><a class="bbcode_url" href="http://www.overclock.net/t/1366322/build-log-my-first-water-loop-to-achieve-5ghz-on-i5-750/60#post_19653359">Water-cooled build</a><br><a class="bbcode_url" href="http://www.overclock.net/t/1366322/build-log-my-first-water-loop-to-achieve-5ghz-on-i5-750/50#post_19639925">4.87GHz run</a></div>
<br><br>
...now it is time for dice! This is OCN, so I just cannot give up <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><br>
I'm going for Dice + Aceton, I have all parts ready, including a pair of Scythe GT 5400 rpm fans <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br>
This is my pot - It's just arrived - I think it looks sweet <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><br><table><tr><td><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1466397/"><img alt="" class="lightbox-enabled" data-id="1466397" data-type="61" src="http://www.overclock.net/content/type/61/id/1466397/width/500/height/1000/flags/LL" style="; width: 500px; height: 667px"></a><br></td>

All the stuff is ready, waiting for dice delivery tomorrow morning <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br><br>
It's gonna be fuuuuun <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br><br>
I promise pics tomorrow and details of my success/failure (whatever - I will have fun anyway).

One of the things that might help you tweak without wasting subzero juice is to lower the multi and try pushing BCLK on air. It'll probably go further on LN2, but you should have no problems going higher than 238.<br><br>
On X58, BCLK was tied to PCI-E frequency... I'm not sure if they're related but it shouldn't cause any hard trying moving PCI-E up to 105 and seeing if that gives you any additional headroom.

Did you mean Socket 1156?<br><br>
On X58 PCIe could be set in bios independent of BCLK AFAIK?

When I say tied I mean that if you want BCLK over ~220, you needed to raise PCI-E. For 260+ you need 118+ on PCI-E.<br><br>
All the above is for X58. I'm wondering if it has a similar effect with P55.

I spent many hours on air and water playing just with BCLK <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"> The highest one I ever achieved was 239. I don't have much experience, but my impression was that the stuff behaves differently in sub-zero - I had to use different levels and combination of voltages for high OC (mainly Vcore and QPI). Close to 5GHz they had precise values - anything slightly higher or lower didn't work.<br><br>
My ideas - please tell me what you think:<br><br>
1. I could not figure out 24x + turbo + 1 or 2 cores combo - I can set it, but I can not get any high OC (most of results better than mine were on 1 or 2 cores only).<br>
2. Windows - I just used fresh Windows 7 installation - I had no issues with starting in BIOS @5GHz, so I imagine that super light version of windows 7 or even better XP could help.<br>
3. I had strange feeling that lowering temps may help <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"> LN LOL?<br><br><br>
PCI-E - I will double check - but I'm pretty sure it's not like that on P55 platform.

Time for some pictures <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br>
Before that, big thanks to Palzen - we did the whole session together. Also thank you to other OCN members for tips and encouragement. OCN is a great community <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><br><br>
The parts.<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486160/"><img alt="" class="lightbox-enabled" data-id="1486160" data-type="61" src="http://www.overclock.net/content/type/61/id/1486160/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>
Preparation.<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486161/"><img alt="" class="lightbox-enabled" data-id="1486161" data-type="61" src="http://www.overclock.net/content/type/61/id/1486161/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>
I love eraser - easy to apply and remove.<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486162/"><img alt="" class="lightbox-enabled" data-id="1486162" data-type="61" src="http://www.overclock.net/content/type/61/id/1486162/width/500/height/1000/flags/LL" style="; width: 500px; height: 667px"></a><br><br>
This approach for bottom insulation is advised by Ivanov - one of best Polish overcklockers - I used a lot of paper, not k-flex.<br>
It worked well.<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486163/"><img alt="" class="lightbox-enabled" data-id="1486163" data-type="61" src="http://www.overclock.net/content/type/61/id/1486163/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>

Ice, baby, ice <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486165/"><img alt="" class="lightbox-enabled" data-id="1486165" data-type="61" src="http://www.overclock.net/content/type/61/id/1486165/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>

More action<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486168/"><img alt="" class="lightbox-enabled" data-id="1486168" data-type="61" src="http://www.overclock.net/content/type/61/id/1486168/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>
With my spare mobo and PSU (gigabyte P55-USB3 and OCZ 600W) I reached only 4.89, so I removed my main mobo and PSU from my watercooled rig (assus P7P55D-E Premium and corsair AX760i) for some more juice. Second insulation was really fast, but it worked as well. <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486169/"><img alt="" class="lightbox-enabled" data-id="1486169" data-type="61" src="http://www.overclock.net/content/type/61/id/1486169/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a><br><br>
In BIOS.. <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1486170/"><img alt="" class="lightbox-enabled" data-id="1486170" data-type="61" src="http://www.overclock.net/content/type/61/id/1486170/width/500/height/1000/flags/LL" style="; width: 500px; height: 375px"></a>
