I am worry
cpu pll v 1.56
fsb 1.26
and nb 1.26
crash occt.
but I see when mother board more 44° is no goog for me
i fink my reaper heat ( hot) too match
i will try to have only 42° when burning
my timing 5 5 5 5 15
refresh cycle time 35
performance level 10
write to precharge delayed 13
write to read delayed 11
actto act delayed 2
read to write delay 7
read to precharge 5
refresh period 4171
command rate 2t

I will test my cpu with a noctua nh-u12p

[Leeghoofd]

Which bios are you runnign Genish , either it's 0803 or 1406 there's no in between apparently... try to pm truehighroller (he's a few pages back) he has got the same cpu as you and think he can help you out better than me with your hardware setup

[genish]

my bios is 1406 (the last)
I have put a 50mm fan to blow over (on) my ocz reaper
and the mother T° down 10° 45° to 35°
I have cpu 468 Hz and ram 10:8 1170 Hz
the pll fsb and nb are always better in AUTO
I try a new test when I evolue to zalman 9500 tu noctua nh U12P
the T° is too much 74° core one

can you say me how I can down the Temp only of the first cpu core is always more 5° of the 2 3 4 core

thank
genish

Greetings to the friends of forum.
My first post.
Voltages in auto are really dangerous?
I wanted to keep this over, but I am only obtaining keeping the voltages in "auto".
Somebody using Q6600@500Fsb?? Tips??
Thanks!!

So guys, nobody you give me a hint of 500Fsb voltages for the Q6600?

My zalman 9700led is not goooood, but in the coming days I will remove, clean and back to see if improvement ....
Thanks!

I have now overclocked my e8400 to 4.2 and its stable see pic below. But the weird thing is. Before I had 4.0 8 hours prime stable. But it was not 24/7 stable and now I overclock it to even higher and it is really 24/7 stable. Can somebody explain why?

Could you post your settings please, also which board is this. Good looking clock you have there.

[An1mA]

When I post in a P5Q Deluxe thread I think I have one too ? xD

Settings
4255MHz (532x8)
vCore = 1.32500v
CPU GTLs = Auto
CPU PLL = 1.58
FSB = 1.28v
DRAM = 2.02v (1:1) @ 5-5-5-15
NB = 1.26v
All the rest: Auto

[Melhisedek]

What is the highest you can go with PLL and FSB Volt using 8400 E0? They add stability to my system but I see most of the people running them pretty low. I'm up to 1.58 on PLL and 1.26 on FSB, if I go higher I can get higher overclocks. What is strange is that higher vcore doesn't help but PLL and FSB do. Perhaps it is only one of them not sure still. In any case

Same question, is it ok to up the PLL to 1.62v and FSBv to 1.28 for everyday use? These settings only my e8400 C0 Stepping would be stable @ 450x8.5 (3.825Ghz). Anything lower than that, it would either restart or BSOD.

my vNB is 1.26v.

Thanks for all your help!

I'm trying to get to 500 fsb stable on my P5Q Pro but I'm stumped and in need of some help to steer me in the right direction. I'm running an E8400, CO revision level, with 2 gb Transcend AxeRam DDr2 6400 (D9). I've been able to get the CPU to go 9x445, 8.5x470, and now 8x490 completely stable, generally needing core voltage 1.36-1.376v in CPUz, 1.38-1.40v in BIOS. I've had the ram up to 1117 stable, or even higher, using 5-5-5-15 timings. The best I've been able to get it to do is 940 with 4-4-4-12 timings. I'm using Ket's modded BIOS 1307 for the P5Q Pro.

The problem I'm having is I'm fine at 490x8, but when I crank it up to 500x8 I get blue screens, instant prime blend test failures, and general instability. I have noticed it will pass small ffts for a while though.
I'm especially having a hard time figuring out where to set the FSB and NB voltages because I don't know where the BIOS puts them at when set to AUTO to use as a starting point for reference. Basically its been nothing more than a shot in the dark so far trying to figure out these two settings.

Here are my current BIOS settings, any help would be appreciated.

Your settings look similar to mine, I can't quote that at the minute as I'm at work but I never got to 500fsb stable, I did however get to 499fsb!! That's prime95 & 3dmark06 looping for 24 hours stable, also the intel burn test too for 50 reps. If I try 500fsb it blue screens as if I'd upped by 20 and not just 1!

It looks like what yours is doing at 500 mine is doing at 490. I have a new set of cellshock ram coming any day now I'm hoping this will give me more options, I'll let you know how it goes.

[BigDMadinko]

Here are my settings, hope it helps:

Thanks for the help, the thing is my cpu seems to need a lot more voltage than yours, I'm at 1.40 in bios just to get to 4.0 ghz, Im wondering if that also means I need a lot more voltage on the fsb to get the same results.

Hmmm, I know I got pretty lucky with this CPU, but still 1.4v for 4GHz seems a bit higher than usual. How much of a vdroop are you getting? Do you mean 1.4v in BIOS or real (after vdroop)?

Have you tried lowering the voltage of NB and FSB to around ~1.26? If not, give it a try.

[Melhisedek]

I seem to have same problem I need about 1.39xx in BIOS (it is 1.38x in Windows) to get stable 4Gig. I have tried playing with voltages but no go E8400 E0

Wow, and that's with an E0?!

What temps are you getting?

[slash777]

Is FSB 480 - 500 possible on this Board ( Q9550 ) ?

[Melhisedek]

Wow, and that's with an E0?!

What temps are you getting?

33-35 idle and about 49-51 load. TRUE cooler + Scythe fan and Antec 1200 case with good airflow.

It is not RAM as I can memtest it at over 500 FSB for hours with no errors. Small FFTs are also stable, not sure how long... perhaps a few hours at least, but using large FFT (using Prime95) gives me errors after some short time... 10-15 minutes. Highest stable overclock is 480x8.5. Even a MHz higher I get errors in Prime. I guess I'm just not lucky when it comes to overclocking components.

If I try and lower Vcore prime fails almost instantly

[carepolice]

Uhm i dont see your problem.... Not every chip is a lollow voltage user + those temps are really great for those volts. Just use volts what you need for you OC.

[Melhisedek]

Problem is that people say these chips shouldn't be run higher than 1.4 No matter the temps, or maybe I'm understanding it wrong?

[CryptiK]

well you shouldn't really run more than 1.3625 vcore according to intel, but many run up to 1.45v, just depends how long you want to keep your cpu. I run my 8400 C0 at 1.336v for 4005 MHz stable, on that vcore I can run either 445 x 9, 500 x 8 or 534 x 7.5 totally stable. Thats using 1.50 vPLL and 1.2 vFSB. Every cpu is different.

[Melhisedek]

Well I'm ok with chip lasting about 2-3 years tops, but am still afraid to run it over 1.4 I have asked earlier what are highest NB, PLL and FSB volts you can run on air as well. I would like to try and max them all out and see... If it gives me 150-200 MHz more why not run a little higher than the most

Try a lower FSB with a higher multiplier. It may be an unstable chipset OC and not the CPU.
