Yeah i pretty much thought the mod would be at me own risk lol. But unless i have a shakey hand when i do it I think i'll be ok. Just to clarify the pencil to use is a 2b right? Or do I have to get one of these conductive pen things?

You can use any pencil, but the softer leads - like 2B require fewer strokes as you put down more graphite at each stroke. The last thing you want to do is to overdo it, so do a few strokes, boot the machine up and run a voltage monitoring application to see what your voltage is at idle, then run Orthos to load up the CPU 100% and watch the voltage like a hawk to see if your Vdroop is cured. What you want is no change at all when you load up the CPU. Mine took 24 stokes of a B pencil so I would think 10 strokes of a 2B would be a good starting point.

Thanks for the advice WJA96 that has given me a figure to aim for on how many strokes I would need. I really do think then that this is the board for me, been humming and arring between this and the abit.

most conductive pens tend to have a silver content, making them to good a conductor for this application, you can get graphite conductive adhesives, which are resistive but its less reversible than using a pencil I recon. the only problem I see with a pencil mod is if it gets rubbed off, if that happens you'll only end up with an unstable overclock.

The big plusses with the graphite pencil as I see it are that they are exceptionally cheap and very hard to do any permanent damage with.

Using Speedfan to check, my VCore stays the same whether im at the desktop or running Orthos, i dont know how acurate Speedfan is but im 8 hours stable at 3.3 on my e6300. stopped the test at 8 hours btw. ive run the most CPU demanding games i have (LOMAC, COH, MTW2) and nothing has made the system fall over. Before the mod i couldnt get 3.2 stable for any more than an hour.
Im just working up my RAM speeds at the mo but once thats done i'l go for 3.4 and see how that goes.BTW, 3.3ghz is stable on less volts than when 3.2 was causing system resets.
Orthos has only pushed my temps above 50C (briefly at 52C) with a room temp of 23C.

What settings you using for your 3.3GHz oc, in particular your nb voltage and vcore? I'm running my E6300 at 3.3 too, I have to have the highest nb voltage to achieve it though, qfsb set to 1886, vcore @ auto+100mv, ram unlinked at 800 MHz 4-4-4-15 @ 1.9v (OCZ plat rev 2's). Runs at a max of 50c under orthos load, cooled by a Tuniq.

Its orthos blend test stable at 6+ hours, not bothered running it longer than that as the system's been running 100% solid for the past 2 weeks of gamesplay thrashing which is good enough for me.

Only thing is I just can't seem to get it past 3.3, pushed it up to 3.4, it crashed entering windows and required a cmos reset, tried a couple combinations between 3.3 and 3.4 but it refused to even post and required cmos resets too. I have to admit I didn't play with it all that much as I was getting fed up of crawling under my desk to reset the cmos, i'll probably try pushing it further when i've got my new office setup and have the case sitting on the desk for easy access!

NB is at max with a 92mm Amber blowing across it (Swiftech chipset cooler arrived today so i'l put that in the loop this W/E) VCore is 1.4+1 iirc (at work at mo). Mem is the Geil value 2x1gig stuff at 5,5,5,15 Auto volts and unlinked@230mhz and working my way up.
I'l pop my cpu up to 3.4 tonight as i know my ram is ok at these settings.
Set your VCore to manual and look to see if you are getting VDroop.
If so then try the pencil mod to stabalise your VCore.

Hi.

What kind of Motherboard Temps get with a decent o/c on this board?
Mine went up to 60C the other night during a heavy gaming session.
Is that too high?

It does sound high - what is your case ventilation like?

 

[pegasus1]

Orthos at 3.4ghz (3399 actually ) and temps maxed at 52 but have settled down to high 40's. Room temp 20.5. Has been running for 30 mins so far.
1.7 on the NB and 1.41+1 on the Vcore (which is still rock solid).

 

[Kaiju]

Man, i'm running 1.4v+1 and my load temps are just under 70C with a room temp of 24C.

Even though my room temps are higher, I may just have to swap my SI-120 for some of that watercooling goodness.

I think 2h for the pencil mod might be better because it gives a finer line. Ive done the mod on previous asus boards and I did have a problem with a 2b pencil being too crumbly. In that case they actually said to break the tip of the pencil off though

 

[Hayley-K]

What are your CPU core temperatures like?

My cpu temps were pretty low idle - 30 and load neverover 40.

Just put everything at stock and it somtimes post sometimes does not. It getting really annoying now. I think I might just have to leave it on standby all the time or somehting.

I will probablly reseat the processor tonight with some decent tim as I have som rubbish value stuff on it ATM as it was all I had when I built it up.

Mine did similar, set it to spd manually and up the volts slightly ?


I had to switch to 1.7v on the NB after going to 1707 QDR. It crashed loading into windows with 1.5v, higher nb volts meant no problems. Ive kept it there since, not massively hotter imo

silversurfer was you mobo not posting, or posting and not booting into windows? As mine wont post at all on the first attempt, then I have to resart, load defults then go and load my overclock profile. If I want my processor at 3ghz.

 

[benskia]

So...where abouts is the NB on a mobo?
Just asking so as I know where to aim a fan at it.

Is it at the top, bottom, back or front?

Cheers.

You want to aim a fan at the big silver heatsink in the middle with Asus written on it.

 

[benskia]

Thanks.

Plus - any idea how I mount a fan in the case?
Is there any such special equipment to help me do so?

 

[EvilGrin]

Right, manually set my vcore to 1.40 +100mV. Speedfan is reading thus: Vcore 1 from 1.47 to 1.455, and Vcore 2 - 3.35v! wtf

 

[WJA96]

Thanks.

Do a search on Zalman fan bracket - should be about £5 I think. Or Antec do a nifty flexi-spot fan for about £10. Or you can just zip tie a fan to the Northbridge.

Now at 3.4, Orthosed for a couple of hours and played COH for a couple more and all is well so far. Its currently running Orthos while im at work so i'l have a look how things are at lunchtime.
Temps hit 55C but the room temps were 24.5C.
If it turns out to be 3.4 stable im gonna set up a summer profile and see how little VCore i can use to get 3.2 stable (for those realy hot days).

I have just purchased the P5N-E along with 2-off OCZ PC6400 DDR2 rev 2 1GB sticks of ram (making 2GB in total)

The board has 4 ram slots labelled DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2

Please could someone confirm which slots I put my 2 sticks into as the manual doesn't seam very clear to me. (I'm not the brightest bulb in the set)

I would appreciate any feedback

Cheers

[Mista.Gee]

For Dual Channel if i can remember rightly it's DIMM_A1 - DIMM_B1. (Two Yellow Sockets).
