Argh,

Strange things happen when I change anything in the BIOS (well haven't tried everything) when i just turned of CPU Spread and then went "save settings and exit" the computer turns off completely, i.e no fans lights, then comes back on, but the monitor doesn't recieve any input.

So i press the off button and then turn it back on again and the computer boots ok, but gets to a point and says "Overclock failed.... press f1 to change settings or f2 to return to defaults" Any suggestions why only changing say CPU Spread would cause this?
And why did my monitor not recieve anything after the reboot?

Any suggestions will be appreciated

That's the normal sequence of events when an overclocking setting is pants.

First boot fails to post, second boot resets the bios and gives you the option to change the settings.

Can't say I'm too familiar with the CPU spread settings. Did you google it yet?

Anyone with a P5K Premium Wi-Fi and Q6600 running circa 3.4-3.6 GHz please could you post your bios settings esp voltages, think I'm on bios 0504 (can't remember as at work) but it is the latest from the Asus support site

Having read various threads, It appears I have some bios options missing so would like to check/compare to others, in particular the "voltage damper" isn't their or is called something else

I'm hoping to hit [email protected] with GeIL DDR2-800 @1:1 @1000 and FSB@2000 or maybe [email protected] with memory divider to 1000 and FSB@1800

Case, cooling and Tuniq with idle and stress temps suggest I shouldn't hit any temp problems, mainly want to understand all the voltage settings as I'm a noob to this

Just checked Asus website - def 0504 dated 28th Dec 07'
Also won't let me run latest Asus Probe either, no errors or anything just doesn't run

Thanks

Are you sure that your memory will run at that speed?

Same here buddy!!

Gone from 0204 bios to 0504 and I’ve lost a few settings in the bios to, voltage damper worked great for me in 0204 why have they removed it in the latest bios.

Also I can’t change the CPU Ratio Control anymore!?! simply can’t open the option box to set it to manual from auto! so Im stuck on the q6600 9 multi.

Also randomly takes a lot longer to boot to the bios splash screen now.

Anyone else running this 504 bios on their Premium?!?

Cheers

Make sure the AI overclock tuner is set to manual
Then in the cpu ratio setting you highlight that and type in the multiplier number eg 6,7,8 or 9, I tried pressing enter hoping to bring up a list but you'll notice in the right hand pane of the bios window it tells you to type in the number, this should now work

Theres def several bios settings totally missing from 0504 compared to many bios screens Ive seen posted, however Ive found one called "load-line calibration" which if you highlight you get these options
disabled - follow intel spec
enable - improve vdroop directly

list of voltage related settings I have :-

cpu voltage
cpu pll voltage
fsb termination voltage
dram voltage
nb voltage
sb voltage
clock over-charging voltage
load-line calibration
cpu gtl voltage reference
??? gtl voltage reference

I've managed a quick orthos run at 9x375 (3375) on cpu voltage 1.35v with memory 4-4-4-12 1:1 @750, all core temps about 56 with Tuniq fan on max, not bothered about a monster o/c so if I can hit 3.5/3.6 without loads of voltage changes I'll be happy

Hi 1080,

Yup just worked out how to input the cpu multi, wonder why they changed it.

Ok, just compared 0204 and 0402 to the new 0504 bios:....

-CPU Voltage Reference is now called CPU GTL Voltage Reference
-NB Voltage Reference is now called NB GTL Voltage Reference
-CPU Voltage Damper is now called Load-Line Calibration

It seems the new P5K Premium bios is using the Maximus equivalent terms, NO bios settings have been lost as far as i can see, they have just moved around and a few have different names.

Going to see how well it overclocks now.

Ok, so I am getting a failed boot when I change just the CPU Spread off. I just tried restarting going into the BIOS and then going 'save and exit' without changing a thing, and then my monitor went blank. Turned comp off and on again, and got a failed boot again!! How come it is saying overclocking failed when I haven't even changed any of the settings, it happens everytime I go into the BIOS. What should I do? Will this be resolved by upgrading the BIOS?

Shirley then you need to change the CPU spread back to whatever it was before?

Ok well I’ve not noticed any improvement in overclocking with 0504 over the old 0204 bios, my q6600 is still prime stable at 3.8Ghz 1.4v and only 32mb pi stable at 4Ghz 1.5v. not got the guts to run more than 1.5v to get it 4Ghz prime stable yet :o

How are you getting on dude??

It does change back when I set everything back to defaults to get past the overclocking error. But I should be able to turn it off without problems.

I managed to change the RAM to 1066 settings then rebooted and that worked ok. Going to maybe update my BIOS, anyone have a version to recommend? Shall I just get the latest?
 
how do you do raid on this thing,

I have a 250 as my os and 2x250 (identical) that i want raided for apps/games/multimedia. Anyone help, it doesnt seem too explanatory in the manual :/ (for instance, How do you get in the raid menu ...)
 
Had a good couple of hours trying o/c

9x400@3600, memory @800 4-4-4-12 required cpu 1.425v, orthos gave temps of 71
7x500@3500, memory @1000 5-5-5-18 no boot with all voltage settings increased
7x490@3430, same problem as above
8x450@3600, memory @900 4-4-4-12 - required cpu 1.43v, orthos temps 74

Currently settled at :-

8x425@3400, memory 1:1 @850 4-4-4-12, fsb1700, orthos small fft pri 10 temps 74
Going to stress test over next 2-3 days

other bios settings :-

pcie 100
dram ddr2-850
dram command rate 2n
dram - manual 4-4-4-12
transaction booster disabled
relax level 3
cpu 1.4v
cpu pll 1.6v
fsb termination 1.3v
dram 2.15v
nb 1.55v
sb 1.20v
load-line calibration (cpu damper) enabled
cpu gtl voltage reference 0.63x
nb gtl voltage reference 0.67x
cpu spread spectrum disabled
pcie spread spectrum disabled

What should give higher fps in games

Got mine at 8 x 400fsb now, with the ram at 800mhz ddr 444-12, seems pretty happy at that, it isnt getting too hot either, topping out at just under 60c under heavy load.

The vdroop is also a lot less than my previous p5b and im using like 1.325v which is equalling about 1.25v under load, lots of settings in the bios that i dont have a clue what they do though
 
Enable cpu voltage damper, 0.075v is still quite a drop for that sort of voltage.

Im seeing 1.53v under load with 1.5625v in bios at 4Ghz, which is a diff of 0.0325v. If I run less vcore I see even less vdroop.

I think you have to have the drives set to RAID in the bios to get the on screen prompt for the RAID menu.
