NB voltage help

[twicksisted]

I currently have my system running 24/7 at 3ghz as my previous overclock was unneccessary 24/7.

Q6600 @ 333mhz X9 = 3ghz (voltage=auto)
Thermalright Ultra 120
Asus P5K-E
4GB OCZ paltinum rev2 DDRII 800mhz @ 800mhz (2.1v)
4 Western digital WD320 RE1 drives in raid 0 on the p5k-e matrix controller
NB voltage=auto (no fan on NB)



Every once in a while (like one a week to every two weeks) I will be on my pc and ill hear a click from one of the hardrives in my raid setup. The PC will freeze and then blue screen for a split second... reboot and my overclock will fail. this dosent happen when stressing the pc, more likely happens when im not doing anything or browsing a web page.

I'm guessing this is due to the 4GB ram needing higher NB voltage as standard on the P5K-E board and was wondering whats a safe level to set this at, considering that i have no extra cooling on my NB besides the heatpipe that comes standard with the P5K-E.

You shouldn't need anymore than 1.37v.

EDIT: Also to add, on my DFI, not currently running any fans on my nb and I do 1.41 for 425fsb stable as a rock. Oh and even possible your PSU could be failing also, but I doubt it if its the one in your specs.

Is the click the sort of sound of a HDD turning off, or a bad HDD?

And is your ram at 800Mhz (i.e you dropped the divider to OC the FSB at 333Mhz)

And do you have 2x2gb or 4x1gb?

well it has options in the bios for
1.25v (standard)
1.40v
1.50v
1.60v

So theres not much finetuning really... just another notch up..
am i right in my knowledge that the NB is responsible for raid etc... and if that is unstable then it can make the raid crash?

also that 4GB ram would need a higher NB voltage?
As this would explain it then... i know my raid drives are healthy.

divider is at 333mhz (800mhz ram)
I have 4X 1GB
The sound is of the HDD's turning off... im 99.9% sure the drives are fine

Actually, its SB Core and PLL voltage, but shouldn't have to up that. Yeah 1.4v would be fine. Just check your temps, anything over 42C should be classified as a "no-no" on the nb.

aaah ok... nice one...
I think that I may tinker with it... problem is that i wont know if i fixed it as this will happen once in a blue moon, out of the blue.
interestingly though its never happened when doing anything stressfull... itll always be almost idle and ill hear the one drive lose sync... like a tick and power down... then freeup and blue screen (which is for a split second so i cant see the message)

what would be a reccomended SB & PLL voltage for 4X 1GB stick of ram & my "four disk raid 0"setup. Im guessing that it probably takes more stress due to four disks being in raid 0

Up your NB voltage just the next notch and you should be alright man.

Look into power-saving options on this tho. Oh and if it helps any you may be able to disable automatic restart on system failure by using the "F8 menu".

@SB Core
Shouldn't have any problems at stock. Usually its around 1.55v.

PS: Sorry for the edits.

You shouldnt have to up SB and PLL voltages. I would say to definetly up the NB voltage to 1.4v cus its 4x1gb and running an OC'd CPU. See how it goes, better to change one thing at a time. if it does it again (which it should be a lot less likely to) come post here again with what happened and we can think of something else to try.

thanks guys...

Interestingly on the power saving modes... the HDD's was set to turn off after 20 minutes of inactivity. I have changed this to never.

but earlier when it did this crash, I was browsing a web page... and must have had like 2% CPU utilisation... and nothing going on... no inactivity... so i dont think it was something to do with this.

Anyways, will up NB voltage as suggested
