Can you all please try to confirm that everything = default but vNB=1.3V will lead to not booting ?

Thanks.

[Pyr0]

if you look at the pic you can see that its not only auto settings

if you set NB voltage to 1.10v it overvolts same as auto setting

tested the NB, FSB and PLL on the P5Q3 here yesterday, and the same thing happens, lowest setting is same as auto

Thanks.

no problem with 1.3v vNB! But i cant boot high CPU VCore...

all over ~1.50v shut down after 2 seconds

[Cob]

I've having problems booting at 1.12v NB, never mind 1.3v.

I'm going to try the 0702 BIOS.

[LUCI5R]

Anyone tried 0704 BIOS yet?

[Chri$ch]

I've having problems booting at 1.12v NB

you know that 1.12v vNB lower voltage is than 1.10v if you overclock?!

[jVIDIA]

Anyone tried 0704 BIOS yet?

I'm here with 0704 with all voltages set to it's minimum value except for the vCore and VMem:

Q6600 @ 3600 ( 8x450 )
2x2GB Mem @ 1128MHz, 5-5-5-15, PL=8
1,4vCore
2,1vMem

Yip. But everything is fine if I set the NB to 1.10v.

I have problems with 1.3 vNB,doesn't boot sometimes
I use 0704 bios

Awesome.
Where can I get more information on PL? I'm not clear about PL and what it really is.

I second that... is there like a generic guide to OC with p45 mobo, I feel like I don't understand half of what is being said here (that's what happens if you fell out of the loop for a year )

[Leeghoofd]

How are you guys dealing with PL and Booster level ?

Anyone with 2x2GB with PL=7 @ FSB>= 450 ?

On my board with 4gb Mushkin ram I get these results with the Qx9650 :

400FSB and Ram at 800Mhz -- Bios sets 13 perf level at AUTO setting -- Lowest manual is 9 (8 doesn't post)

400FSB and Ram at 1003Mhz -- Bios sets 10 perf level at AUTO setting -- Lowest manual is 7

400FSB and Ram at 1066Mhz -- Bios sets 9 perf level at AUTO setting -- Lowest manual is 7


450FSB and Ram at 900Mhz -- Bios sets 13 perf level at AUTO setting -- Lowest manual is 10 (OCCT stable)

450FSB and Ram at 1081Mhz -- Bios sets 10 perf level at AUTO setting -- Lowest manual is 8 (OCCT stable)

500FSB and 1000Mhz ram is perf level 10 (OCCT Stable)

500FSB and 1200mhz ram is Perf level 8 (OCCT Stable)

I have to admit I never went over 1.5NB voltage to test, I tried a quick boot with 1.7Nb voltage but whenever I set a lower PL value it doesn't post or is very unstable in Windows... Think P45 is a bit crippled here over P35/X38/X48
but makes up for it with heavy and easy FSB clocks...

Awesome.

PL is performance level : it's ram related, I'm no technical geek but it increases overal bandwith and lowers latency... overal with this board if you can run a divider (so not 1:1) do it... you are rewarded with a lower PL which brings more performance... I've summed up my findings in the above post with early tests on which PL level to expect... I don't run weird FSB ranges I only do 400 - 450 and 500

I haven't been out of the loop for a year and I still don't understand half of what is being said here ... primarily due to the mammoth change in BIOS, coming from the P5W DH bios, which was essentially 2 years old. The BIOS on the P45 has changed so tremendously, I'm basically accumulating bits & pieces of information from here & there. We definately need a new, P45 updated OC Guide.

Anyhow, Lee, thanks for the info on PL.

lol, what a coincidence, I'm coming off p5w too... it was a good board but it's showing its age p5q seems to be a very worthy successor, for the price, of course

[Cob]

Now I'm getting somewhere...

[LUCI5R]

Now I'm getting somewhere...

Totally Awesome!!! Can't believe you hit the magic 4.0Ghz (500X8)!! That is really, really promising. Do we have the same memory kit? (OCZ Platinum Edition 4GB (2X2GB) PC2-8000).

Would that 1.4v hurt the CPU? It's higher then it's rated 1.3v

Now - I need to get my system to where you're at - And get it Prime Stable!!

Start reading up guys These guides I found very helpful when I started seriously OC'ing. Hope you find what your looking for.

NOT WITH YOUR FREEZER !!!! get something better before overclocking ya quad !!

What's colder than a freezer? LN2?

Thanks, but all these are pretty old and none of them is p45 specific Put it another way - I've already know how to oc in general, or how to oc conroe on a 975 board (p5w specifically). Now, I'm moving on to wofldale and this board and it's more complicated - more options, etc, so I would like to know what does what. Your links are helpful in general but not with this board, unfortunately.

Any recommendations?

Move on to watercooling!

[TheKarmakazi]

Any recommendations?
Thanks!

How much of an overclock are you looking to get? Also, what currently are you using for cooling?

As for other solutions there are many, but it depends on how much you want to spend. And also if your looking for 24/7 overclocks, or temporary extreme benching overclocks.

[Cob]

Do we have the same memory kit? (OCZ Platinum Edition 4GB (2X2GB) PC2-8000).

Would that 1.4v hurt the CPU? It's higher then it's rated 1.3v

Now - I need to get my system to where you're at - And get it Prime Stable!!

Yeah we've the same kit. It should do 1040mhz without tweaking the sub-timings.

Nah 1.4v won't hurt the CPU. It drops considerably under load.

And Prime95 stable can wait til the w-end. I alreay know this chip is 8 hours stable at 3.8ghz on P35

[TheKarmakazi]

What's colder than a freezer? LN2?

Artic air, water chiller, single stage phase change, rotary phase, cascade phase, dry ice and LN2.

Thanks, but all these are pretty old and none of them is p45 specific

Well your PL question wouldve been answered by the RAM Timings article. Not to mention P45 just came out and there probably arent detailed guides yet for the people who dont want to do it on their own.

Also, many of the terms apply to P45 even if the article refers to P4's (like EIST/C1E/ram timings/etc). So why not just figure it out yourself? Thats part of the joy of overclocking, then when you get your next mobo, you will understand it all better (and maybe wont need a guide).

Cob, post here a screen of the everest memory bench @ 4000 and mem 1:1
