I think you should read what I posted again, 1.65v is the most for MCH volts in bios rev 706 available in bios option.Quote:

I'll give the 414mhz 1:1 *9 a go later on today.
Just flashed to the new 711 bios, will try over this weekend to see how she overclocks now. :)
i had the strangest thing happening, i began with oc of e6300 in the past days using a 0507 bios thinkig that i will reach high fsb, but it didn't want to be stable at anything above 330 fsb, i tried everything, even raising vcore to 1.4 but it didn't do the trick. i thought i had the first bad chip that wouldn't seriously oc, but then as the last resort i changed bios to 0711 and now i'm runing dual sp2004 at 465fsb and it seems stable at 1.375 vcore and temperatures are at 59c in coretemp cooled by big typhoon. so i don't really understand why the 0507 bios was no-go for me but it works for other people, whatever the reason i'm just happy that sorted out and it seems to be a proper chip. so i got some oc and testing to do what it can really do.

I am having a heck of a time trying to get a stable moderate OC that can pass the blended Orthos stress test. I have read many of these threads, so forgive if I missed something. But here goes. The best I can get is about 2 hours (which I guess is not considdered stable correct?) The settings are:
FSB(375- would like 400)**DRAM(750)**PCIE(100)**PCI(33.3)**Spread Spectrum(disabled)**DRAM Voltage(2.1)**CPU Voltage(1.4)**FSB Voltage(1.3)**NB Voltage(1.45)**SB Voltage(Auto)**ICH Chipset(Auto). Under CPU Config, I have everything set to "disabled" besides Vanderpool Tech.(set to enabled). Under the NB Chipset, I have: Memory remap(disabled)**Config. DRAM Timing by speed(disabled) and the following timings (top to bottom) 5*5*5*12*6*42*10*10*10*10 Static Read Control(disabled) Latest BIOS 0711 (I think thats the #)
I have tried so may combinations that my head is spining. I ran small FFT's and that was ok, large FFT's didnt run long before it failed. I removed each stick of ram, and it still failed. I am VERY new to this (first time), so are my settings ok?? what am I missing, or what else can I try? Is my PSU ok, should I try new memory (ugh $$$ but willing if it is the problem). Again, sorry if this has already been discussed, or the wrong place, but ANY help would greatly be appreciated.:confused:

The rest of Voltages (nb,sb,mch set to auto)
Ram settings are ok.
Vanderpool Tech.(set to DISABLED)
Try again.
fsb set to 401. 400 may give you problems
Ok someone please save me from suicide here. My E6600 will simply not clock over 351Mhz even if I drop the multiplier. I have trawled through this forum and I have done what everyone has suggested with regards to disabling CPU options, changed voltages (dropped and increased) but I can't get anywhere.
I can post at 355 Mhz but it won't stabilise (Prime finds error after a few seconds). If I try to go higher than this it won't post at all. My memory should be easily able to handle more (Geil Ultra PC6400 2x1Gb 4-4-4-12 and I have tried slowing the memory down with slackest latencies). I have the latest 711 BIOS on the P5B Deluxe.
Judging by so many other peoples' success at getting over 400Mhz I'm sure this thing should be able to handle more. There shouldn't be a problem with PSU (Hiper Type-R Modular 580W) and my graphics card is XFX 7900GT.
If anyone has any idea how to break this barrier I would be sincerely indebted to them and in complete awe of their overwhelming overclocking skills.

I have the 0711 bios and Vanderpool Tech.(set to ENABLED) is greyed out and will not let me change setting.
you can only change Vanderpool Tech. after a cold boot
A cold boot you say? Ok, that's what I will do,
Thank you
cold boot worked, thank you sir!
First Post very useful, Answered alot of my questions.
Some info that might help some
my e6600 air cooled on p5b vanilla would only run up to 427 x 9 and even there it wast too stable. Ran fine, spi 1M, regular stuff, but no 32M super pi
Had voltage pinned at 1.7 in bios which = 1.574 in probe
so along comes vapochill and now it won't get over 4.3Ghz at either 8 x 543 or 9 x 483
It is a week 28 chip
My next step is some voltage mods if I can find clear pictures and/or instructions.
Just thought I'd throw that out.
With my chip, the lack of sub-zero cooling and stock p5b got me to 3.8Ghz air cooled and then 4.3Ghz with vapochill
Just some food for thought..
PCIE Frequency - so what's the story and rationale behind the recommended settings for this? I've read of people recommending 96, 100, 101, 120 most frequently. So what determines the best recommended value for PCIE Frequency?
Shocking how many 1st posters are in this thread! :eek:
well I guess we have to start somewhere.Quote:

pcie could do 120 or even better
In the old days, you could tweak the pci buss. I had plenty of devices that ran at over 50 Mhz, but my board only has auto or 33 Mhz
hope that helps
I thought I had a stable oc at 3.5 GHz with my E6600. It passes Orthos blend for 12+ hours, and I can play World of Warcraft at 1680x1050 with all the sliders maxed out, but I ran 3DMark 05 this morning, and it caused a system reset twice.
My settings are as follows: FSB 390x9, Memory @ 4:5 (DDR2 975) 4-4-3-8-4-22, VCore 1.5v (reads 1.45 in AI Suite), Vdimm 2.3v (reads 2.25 in AI), FSB Term. and NB volts are one step below the highest setting, SB volts at auto, PCIE 100, PCI CLock 33.33. Everything else is as in the op.
What would you guys suggest? I really don't want to increase the Vcore or Vdimm, besides, if either of those was the problem I think it would fail orthos. My best guess is to increase the voltages to the NB, FSB Termination, and SB. What about increasing the PCIE frequency? Thanks for your help.

How does this board compare to the P5W DH Deluxe for overclocking.
It could simply be your PSU not being capable of giving your gfx card enough juice?Quote:

When I try to boost other voltages I'll get a blue screen (usually the IRQL_NOT_LESS_THAN... message) when I play some games (Company of Heroes in particular)
