I'm stuck at 466MHz with 4 sticks. Plus most P5BD's can't do 500MHz FSB in click 4.Quote:

But, I don't because at 1:1 that would give me a crazy bus speed. I have run only two sticks at 3:/4 at over 440MHz x2. But I have a CPU speed problem at that x. Anyway with air I am happy at 3.36 GHz.Quote:

I don't know, since I haven't got 2x2GB to try. I give up on P5B-D when i can't get 445FSB with 4 stick so i ditched the board and got myself a P5k-E, 500FSB with 4 sticks easy.Quote:

When my FSB is heavily overclocked (say 450+), during the boot process sometimes my video card isn't recognized. This gives me a blank screen as it boots through Windows.
I can fix it sometimes by powering off the computer, then the PSU, and restarting. However, lately it seems like the problem is happening more and more often (I am also pushing the FSB harder and harder with the E8400).
I think I might have figured out what the problem is but I don't know how to fix it. I lock my PCI-E frequency at 101 regardless of what I am doing. However, I remember reading somewhere that the P5B series behaves better if you overclock the PCI-E frequency along with the FSB.
Can anyone give me any insight into this? It is hindering my ability to run at higher speeds as it will take anywhere from 6-12 boots to get into windows. Half the time it does boot it states "overclock failed" blah blah blah enter the BIOS,even at settings known to be 24/7 stable.
Thanks.
Just a little more info, I've tried swapping video cards and it doesn't fix it. I've also searched this thread and didn't come up with anything...that and its kinda hard to sort through 186 pages or so.
EDIT: I guess it won't display my sig yet. Hardware is...
ASUS P5B-Deluxe C2 (1226) with E8400 (testing)
2gig G. Skill DDR2 800
ATI AIW X1800 XL
D-Tex FuZion/MP655/Black Ice Extreme III
Corsair HX620
Silverstone TJ-07 Case
I have the exact same problem on my P5B Dlx but only when using Stand By mode. At a FSB of 460 MHz all is OK going into and coming out of Stand By mode but at 470 MHz it will go into Stand By mode but all I'll get is a blank screen when it tries to resume.Quote:

Not very kind, nor constructive these kind of answers. Not a kid's forum here. If you can't help, better shut up, right!!Quote:

I have mobo volts as high as I dare, I'm on
Vfsb 1.40 (have tried 1.45V)
Vmch 1.45 (have tried 1.55V)
Vsouth=1.6V
running Ballistix 8500 at 1:1, currently 5-5-5-15, 2.15V
running 4x 1gb modules
mobo temps are quite high (is system temp southbridge ??)
even though case is well cooled ... system temp idles about 48C and goes up to about 55C under load worst case
cheers, Mark.

You see, I can boot into window with 460 FSB and do dual SPI 32M, But when memtest I get error at the range 2020MB-2024MB, and 4040MB-4096MB in test 5. I change my mboard P5K-E and the ram work great 500FSb with 4 modules no problem.

It's a forum, so people can't guess what's in your mind. Your answers should be helpfull for all. My point of view, not meaning to be rude :)
Let's close this comments as the question was answered
Otherwise, people getting their Q6600 above 400 FSB stable on this board are lucky. I tried two boards and Prime95 small fft is stable, but nothing above 390 FSB is stable with OCCT in RAM mode. This is with many RAM combinations and any NB voltage/timings... combination...
Moved just now to a P5K Premium, my results will show in my sig.
I'll just advice people to check stability with OCCT in RAM mode as the NB and RAM are limiting on this MB for high overclock with a quadcore

What a joke !!!! P5B does a FSB over 400 no problem. Must be something with your skill, knowledge or components. I guess the first two.
I am testing now an E8200 @ FSB550MHz with 7 multi! :D
Very easy to flaim people when you don't know them. Especially when I see your sig with poor OC when I fly at 3.8GHz on a P5K and 3.6 on a P5B with DDR2 above 1000Mhz at tighter timings than yours. So hey, go to school, improve your specs, and come back.Quote:

edit: Looks like you're still confusing quadcore and C2D overclock potential and FSB limits
P5B Deluxe FSB capabilities...?

very nice :)
After my post above (thanks for the replies) I decided to ditch the overclock and reduce it somewhat...
@ 3.45 gig
Vcore = 1.51V, Vmch = 1.45V, Vfsb = 1.4V fsb, Vsouth=1.6V
Prime stable
@ 3.31 gig (so not that much lower)
Vcore = 1.41V, Vmch = 1.25V, Vfsb = 1.3V, Vsouth = 1.5V
Prime stable
thats a lot of extra volts for not much extra overclock - so sticking to no.2 I think
Fair enough:up:Quote:

Sure I flamed you. The topic is not PK5 vs P5B.Quote:

At this point, my goal is 24/7 operation uptime without errors in Windows Event Viewer. I use my computer. I just don't Fire it Up for a quick unstable OC.
Oh, yes, I already said you're well known to be a flamer. Getting frustrated, when wrong, can be cured. No need to get your guns outQuote:

Sure you have to agree your mind, if it does the 400 FSB stable on a quad or not?Quote:

Anyway, seriously, to sum it up:
The P965 chipset rocks with a C2D but is FSB limited with a quadcore CPU, this is known from ages.
Most P5B deluxe series will overclock your C2Q to a 380-420 FSB, some roxor boards reached 450MHz. I till now, never saw a report of a stable OC on a P5B deluxe over 400FSB on a quadcore except the easy to stabilize small FFT in Prime95. Personally, Small FFT are stable for 12h at about 415 FSB, than no boot. OCCT in RAM mode and F@H are rock stable only at 390 FSB maximum
On a C2Q, above 520 FSB is far from being the rule, only noobs think the opposite because of some nice screenies. Only few Roxor CPUs and motherboards can do it.
Now, I saw boards doing a 450FSB screeny on a Q6600, but they are not legion
So people looking for a high overclock on C2Q, just have to know the limits of this board
Oh, yes, I already said you're well known to be a flamer. Getting frustrated, when wrong, can be cured. No need to get your guns out

I don't recall flaming anyone on this board before. Since you have researched me, show me where.
