**- Official Asus P5K Thread -**

Backed down to 356 FSB @ 1.328 v (CPU-Z) 3204mhz Q6600

3DMark06: 16981

This seems the highest stable OC I can get :( - Thanks for all your assistance though. I've learnt a lot :)

You do seem to have a wall at 360mhz regardless of vcore. Your bios settings seem perfect, you have a good mb and your ram is WELL within its limits
Temps also seem a-ok, im a little stumped tbh.

Maybe give your NB and PLL voltages a wee boost. say 1.5/1.5v~ respectively, worth a try I guess.

I'll give it a shot in the morning and let the thread know the results :)

It is strange, ran Prime95 overnight on the 356FSB for 12 hours (seperate Prime for each of the 4 cores) and solid as a rock, temps were at 52,51,51,53) yet I up the vcore to 1.4 / 1.5 and that is fine, but the slightest change in FSB and it BSOD, its not like it is fails Prime after say an hour, or 30min! I'm lucky if it even boots without BSOD! Yet back it down again to 356 and it couldn't be more stable! Really odd!

Thanks again

Sorry, one more question:

Seems my memory might be unstable (Prime95 on the Blend Test) fails after Test 4!!

One can we do to attempt to increase memory stability? (more voltage? - Memory is G.Skill 4GB DDR2 PK PC2-8500C5 (2x2GB) CAS5 Dual Channel Kit installed into the yellow ports on my P5K Premium - Current voltage is 2.05 BIOS reported voltage)

Thanks
 
LOL - is that a lot!!

(incidentally I did lower it to approx the 800 mhz mark and its much more stable - I'm up to about 3.4ghz at the mo...)

Thanks,
D.
 
P5 K Premium black pearl

Just been having a play about in bios and came across something i thought might be strange.....

Can anyone tell me why i can not alter the CPU Ratio Setting's they are stuck on Auto and i have tried loads of things to get into them but to no avail

Thanks Andy

What is FSB Strap to Northbridge?
Click to expand...

When your computer starts up, the CPU says to the motherboard, I'm a 200/266/333MHz FSB CPU. The motherboard has bootstrap settings to make a CPU run stably at those speeds, and that's what the FSB Strap to Northbridge sets up for you.

It loosens internal timings and increases voltages, so the higher you go, the hotter and slower the system runs. That's why sometimes a massively overclocked PC can feel sluggish. You have the processing power, and the benchies to prove it, but the user experience is often quite poor. Hence it is almost always better to run at the top end of a lower strap setting than the bottom of a higher strap setting.
 
Good answers to the FSB Strap to Northbridge question. I didn't know much about it myself and have always left it on auto! :o

Highest I've run my board is 475MHz which worked fine, if I'm gonna have a bash at 500MHz-FSB you saying I should set the FSB strap to 333MHz?

Perfect answer, thank you very much :)

Auto best then? lol
 
Bought a Medion Desktop, it came with an ASUS P5K31-VM (well that's what cpuz id said ) and a Intel core 2 quad Q9300 and 3GB Ram. My question is can I overclock this MB ? (not by a great deal) The FSB options in the bios are grayed out, indeed doesn't seem to be a lot of options in the bios which is an AMI Bios rev 0009

Most likely an oem asus board with a partially locked bios, sometimes you can get a retail bios that unlocks the overclocking features. if asus don’t support it on their site theres not much hope tbh.
 
Im having trouble getting the marvel ide driver to install on my p5k se
under mode it says not applicable in the device manager, shouldnt it say something like udma 133:confused:

machine feels like its stuck in mud:o
 
I've bought one of these B-grade and it's just the board in a bag. I've downloaded a manual and read it just in case there was anything unusual. I have two minor questions as a result:

What pins should the chassis intrusion jumper cap be on? The manual says pins 3-4 if this feature isn't being used and that this is the default. The board came with the cap on pins 2-3.

There are repeated advice sections saying that if using a dual core CPU, be sure to connect the chassis fan to the CHA_FAN1 header to ensure system stability. Is this just a clumsy way of saying that a chassis fan should be used, or is there some reason for using that header specifically? I have all my fans on a fan controller, so I don't want to use that header.
