**- Official Asus P5K Thread -**

Bazza, that does seem a bit too hot. You might want to try these things;

Lap the IHS on you cpu. (There's loads of threads on this) Although the temps are even between the cores so you may not see an improvement with this.
Re-seat the apogee drive block making sure you don't use too much paste.
Make sure you have the lowest possible vcore for the cpu speed you're running.
Leave all the voltages on auto except for vcore and vram and only change if you have stability issues, but at that bus speed you shouldn't need to.
Tidy up your cables with cable ties!

If the temps are still too high then I would go for the 220 swiftech rad with the integrated res as you can just do a straight swap for the 120 you have now with out forking out for the whole kit.

Hope this helps.
 
If i overclock my Asus P5K Delux to 400fsb.

I can't get it to keep the PCI-E 16x running at 16X it keeps defaulting to 1x

This board should do 400fsb as it will take the 1600fsb 45nm quads.

At the moment its getting really really annoying as i can't overclock my chip with out gaming performance going

Temps on the board seem fine. My PSU is a Corsair 520watt power my sig. So should be fine.

Anyone got anyideas? I'd ran out of bios's/ bios settings to try

I would definitely recommend turning the CPU TM Function back to enabled. This function controls the Thermal Management function in your processor which allows it to throttle the clock speed if the temperatures reach Intel's recommended maximum of 80-85c. Seeing as you have said that the temps once got to 80c you definitely don't want to turn the automatic throttling off.
 
Anyone find that this motherboard requies more voltage for a stable overclock than other motherboards?

I just changed from a Gigabyte GA-965P-DS3 to an Asus P5KC. Tried to use the same voltages I was using previously. Orthos Blend ran for about 6 hours before the computer froze, then I was getting intermittent freezing/crashing.

I have now set all the voltages to auto, which seems to be stable. Does auto mean that the motherboard will just pump volts as and when required? my CPU used to be set to 1.3375V on the old motherboard, but on auto it seems to be taking 1.4V, according to CPU-Z and SpeedFan.

Is there any reason not to use auto for voltage settings?
 
Ok I've reset the CPU TM Function back to enabled, removed the drive, cleaned both surfaces and remounted it using the minimum AS5 ensuring it is a thin coat evenly distributed. First boot, same temperatures. Next I upped the voltage to the fan from 7v to 12v and wow what a difference. Apart from the mahoosive amount of noise the core temps have dropped below 70c at full load. They average out at 65c with the cpu at 53c. That's a 10 degree drop for the cpu and 12 degrees for the cores.

At 390x9 the core temps border on 69c-70c and at 400x9 72c-75c.

So maybe now all I need to do now is upgrade the radiator to something like the 220 Swiftech and hopefully these temps will drop even further. I'll get to a stable 3.61ghz if it kills me :D
 
Well done on getting the temps down Bazza. I am in the same boat with regards to temps/fan speed as I have to have my fans on full (AC7 fan and 3x120mm case fans) when running Prime 95 or Orthos. Nothing really stresses the processor as much as them so I run the fans on full for stress testing and keep them on low for general usage and gaming.

Running any game or any other application only raises the temps to around 55c on mine with the fans on low, but Prime takes it to 67c with the fans on full. Keep us posted if you have any luck getting to 3.61GHz, I am debating whether I should go for 3.6GHz myself with my E2160, I am at 3.42GHz at the moment and am only 180MHz away from the 100% overclock. :D
 
Don't encourage me LOL :D I think I will be giving it a go soon, its just the amount of time that takes to prime that puts me off. I have never really been keen on running prime at night or when I am out of the house.

But tomorrow I will be finishing college at 12pm so I am predicting another overclocking session form 1pm onwards ;) Have you had another go at yours? I don't want to come on the forums tomorrow with a 3.6GHz 8hour prime shot if your E2160 is going to be feeling jealous :D

That's very thoughtful of you but it's ok.........she aint the jealous type!

Gonna give it a little push for 3.4ghz at the weekend. Out of the country with work right now so it'll have to wait.

What vcore did you need for 3.4ghz? Are you using x9 or x8?

I don't prime for loads of hours to be honest. 4 hours is the most I've done. Rather spend the time using the thing really! :rolleyes:
 
Vcore was 1.55 bios / 1.53 idle / 1.52 load for 3.42GHz, That's running 380x9 on the P5K-E. I know what you mean about not letting it run for ages, I have never had a prime session fail over 2 hours, it always happens before then if its going to happen at all.

The hardcore prime faithful will always be quick to show screenshots of it failing after a long period, I saw one the other day in another thread where it had failed after 14 hours... that has to be some sort of power drop/surge issue though. I really can't see how it could fail after being stable for all that time. The only reason I do 8 hour sessions is so that I have screenshot proof to help with selling when it comes to upgrade time again :p
 
Thanks, I had a try going for 390x9 and 400x9 but with no luck. I think its my ram that is holding me back rather than the processor or motherboard. I had to build the pc on a ultra low budget and had to compromise between P5K Vanilla and DDR2-800 ram or P5K-E and DDR2-667 ram.

Needless to say I went for the latter option and only have DDR2-667 ram at present. For the clock of 3.42GHz the motherboard is running at 380x9 and therefore the memory is running at DDR2-760 which seems to be its limit. I tried adding some more volts and loosening the timings but it doesn't want to know at all. I should be getting some new ram soon so I shall try again shortly.
 
Hi Guys

Just decided to give my present OC a more thorough test on Prime and it stays great throughtout small fft's yet starts giving me errors when I use blend after a couple of minutes. I would assume that it has a problem with my ram settings if that's the case, as it's tested more in Blend?

Settings on the ram during Blend are 5,5,5,15 2T, 2.1v. Memtest passed with no problems and all the other settings are as recommended in the overclock guide for 3.2Ghz (400x8). Any ideas?

New to OCing.

Thanks!

Hey,

Got my p5k-Premium, running well with a q6600, and 2 1GB Ballistix 1066Mhz RAM modules.

On Everest it tells me that I am running with a 12:8 DRAM:fsb divider, with 266 fsb and therefore 400(800) Mhz ram. I want to be running my ram at its best.

Is it best that i change my mulitplier, or if I am probably going to try a first time overclock, just start tinkering with the fsb and let my ram increase freq that way?
 
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
 
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
