Asus P5K-Deluxe & E6700 Batch# L633A557 Overclocking Success: Low volts & High Clock!

After weeks of tweaking and Orthos stress testing, I think I've found my perfect sweetspot for my P5K-Dlx + E6700 combo.
Please feel free to use my OC BIOS configuration below for reference purposes. I'd like to also give out my special thanks to EVA2000 and numerous other members who gave out their generous tips and pointers.
This is what makes the whole OC community so great:up:

Great results! I've been following Eva's and your own progress as something to emulate while clocking my E6700. Currently have it at 9x389 for 3.5GHz at 1.400V BIOS (1.36V according to Asus probe).

Did you have to put a fan over your NB to get your overclock stable? I found that @ 8x400 I don't need it, but at 9x389 I do.

very nice.. :) congratz on your OC.. :)

eva2000 is really an asset of the community.. I can also name FCG, raju, Tony, dinos22, and many more.. :)

Nope, no fan over NB and Ram sticks (Recommanded, I know)

However, becouse I've massive air flow and ventilation within my Antec 900 so I can probably still get pass by without active cooling on the NB. The Asus P5K-Dlx stock heatpipe based chipset heatsinks should be adequately enough for high OC but may be not enough for Xtreme OC beyound 550+FSB or 4Ghz+ for example. In that case, active cooling or water cooling should take in place. Overall it's still a satisfying OC result on air.

Please check my sig for detail hardware configurations (ie. fans setup)

defintely, yeah I recognize most of the names you mentioned. Those guys are awsome! I can never come close to those guys but I still would like to share my OC findings with others here:)

Awesome. Thanks for the results, as this is pretty similar to the system I am building right now...makes me strive to see if I can at least get to your clocks :)

Good work Tiramisu!
Are you still going to go quadcore even after you have gotten such terrific results with your e6700?

were the settings like the fsb strap, dram static read control, and PCI-E frequency necessary for this OC result?

Also, can we see some pi 32m times?

Congrats Tiramisu!

nicely done XtremeTiramisu :up:
my e6600 can work on high clocks and low voltages too.

have you tried 9x400 or 10x365? see how much vcore they take.

1. In terms of the applications I use, a highly OC'ed C2D would actually yield better performance than a OC'ed quad on air. I'm not an user who'll fully utilize all 4 cores because the applications I use aren't mutil-threaded and most of today's applications aren't written to benefit the usage of an quad.

But having said that, the trend is moving towards quad. A year from now, statements about C2D vs C2Q could change and I'm in the situation of building my second PC so in the end I might ended up choosing a Q6600 G0 stepping. I think the biggest challenge I'll face will be the heat issue even I'm using high-end air cooling and the G0 is suppose to run cooler than the current B3 stepping from quads. The E6850 may be the best choice for air cooled OC'er but reading from some overclock-ability of an ES E6x50 and actual retail E6x50 indicated that the OC result may vary. When I take this into account, I really don't want to take my risk eventhough an E6850 is capable of OC up to 4Ghz on air but the amount of voltage is through the roof as well from most of the results I've seen so far. Since I already have a golden C2D that's capable of doing what some of the better E6x50 can do but with less volt, I don't think I want to take the risk of buying a E6850 and ended up not doing AS good as the current one. Temp wise it's going to get much better than my rather hot E6700 with its given volt.

Simply, I feel it's time to start a new chapter, thus Q6600 G0 should be my next investment in a CPU. At roughly ~$300, it's really hard to turn down. For Vista users such as myself, I think the OS alone will benefit the quads as well.

2. FSB Strap: I've being testing it with it set to 266 strap but I was told that AUTO gives you a little more bandwidth. This I'm not certain becouse I havn't done any in-depth testing on it but I don't think it matters much anyways. Set it to AUTO will give you all choices of dividers.

3. Dram Static Read Control should be set to Enable for P5K-Dlx. It gives you more bandwidth and there will be no strap change when it's set to enabled. Strap change occurs after FSB499.

4. PCI-E set to 105 isn't really necessary but I changed it anyways just to get rid of a potential problem due to overclocking. Setting it too high isn't favorable for 24/7 use.

9x400=3600 and 10x365=3650
If I remembered correctly, I think I only need ~1.35v Orthos loaded to get those clock stable.
Becouse I'm using vista x64, I can't open coretemp or Intel TAT but my CPU VID is 1.25000v and that's my E6700's stock voltage.
