**- Official Asus P5K Thread -**

I'm having trouble trying to overclock my Ballistix PC6400 RAM, at 4-4-4-12-2T and 2.1V it can do one pass of Memtest86+ at 457MHz however I haven't let it done any extra passes as it was just quick testing. It doesn't seem to be stable in Windows Vista because when I opened Super PI, the program crashed after trying to start a 1M calculation.

At 5-5-5-15-2T and 2.2V it can do one pass at 510MHz. If I push it to 520MHz, the PC doesn't display anything at saving the settings in the BIOS.

Do I need to adjust the following voltages after CPU Voltage in the BIOS, such as CPU PLL, DRAM termination etc in order to provide more stability?

Currently I've got my E6600 at 3.2GHz using 1.35V and my Ballistix's at stock speeds and timings (400MHz and 4-4-4-12-2T) at 1.9V which is over 12 hours Prime95 stable :)
 
You shouldn't need to alter any of the voltages other than the standard DRAM Voltage setting to increase memory stability; at least i didn't have to, anyway. My Ballistix PC2-5300 are 22-passes-on-memtest-stable at 471Mhz, 4-4-4-12, 2.1v- if that's any help. Are yours stable at these settings?
 
Can anyone tell me what this voltage damper an "vanderpool technology" options do? :confused:

Im using the garden variety p5k, any reason to update the bios?

If your using the standard P5k then the voltage damper does nothing on the deluxe version it stops the vdroop. An easy pencil mod soes it on the standard though.

As for Vanderpool see here
 
Just gonna wait till my new hsf gets here tomorrow to see how much voltage i need to reach 3.2. Is the vdroop paticularly bad on these boards or can it vary fomr board to board? From what ive read even cpuz doesn't always read the voltage accurately.

has anyone got any sata issues, the mobo corrupting the hard drive? it seemd to start and stop,, only when you put 4 in.... when i leave the main drive in it works perfectly.

I have the exact same problem as you. Just purchased the board brand new (Asus P5K Deluxe) When I plug in x3 SATA II drives, and a SATA DVD/RW the primary boot drive does not detect, and is very Intermitiant .... Also a blue screen of death appears when the drive does detect and boots into Vista x64. Anyone else experiencing these issues?? :mad: :(

With me for example, the difference was around 0.08v between set in bios voltage and actual and it also drooped another 0.02v on load, so I was a full 0.1 less than what I set in bios when running Orthos!! not good.

Now, i set 1.5375v and it shows 1.52v and no vdroop now, in fact it goes up 0.008 to 1.528 :)
 
Getting mine tomoz. Do you recommend i flash it to the latest fbios as soon as everything is together and before i install a OS?

I'd wait a bit first, and make sure everything is working ok. I haven't had very good experiences with the latest BIOS, it severely limits my overclock and i achieve higher clocks with 0311.
 
ive tried the latest pk5-e bios (503)

added some extra bios options
windows loaded with new pci-express bridges
or something along them lines lol

not much in the overclocking things for me
