** The Official ASUS P5N-E SLI & Ultra 650i Thread **

Hayley-K said:
Hey just got the P5N-E SLI and have been having trouble overclocking as I am not familiar with the bios. I have currently got my e4300 to 2.7ghz but it fails to post any higher. I have the latest bios installed

Could anyone give me any tips on what to tweak. For example what do I need to do to the LDT frequency, and what are the best voltages.

Also what have other people with this combo managed to get out of their processors?

Thanks,

Hayley

As far as I know, everyone is just leaving the LDT on 5x, but you could try dropping it to 4x and see if that makes any difference.

From the E4300 overclocking thread you seem to need a lot of volts to push the E4300 - 1.4V+100mV minimum and a lot of folks are at 1.45V+100mV. The Idle temperatures look horrible, but the max load temperatures aren't actually a great deal higher usually.
 
Just got it into windows at 3ghz with 1.6v its not orthos stable regardless of if I run it with 1.6v or 1.45v and everything in betwen. If I run a 3dmark I get blue screens just wnated to bench it a 3 then run it lower.

What are your other voltages at?

1.56 going through the NB everything else is on auto.

Have you got some decent cooling on your northbridge also?

I just put a spot cool on the NB and now its running stable. I have had orthos going for 20 mins now and am going do some serious benchmarking. I did have an opteron 175 which would only get to 2.6 so I want see how much this new set up beats it by.

Thanks for all you help guys, its just a little picky I think.
 
The zalman is here, unfortunately I've been out to a formal and had a bottle of wine. Is it worth the risk of fitting it now, or shall I wait till the morning :confused:

Best done in the morning I think. You could easily fry the northbridge if you managed to fit it with any gap between the surfaces

I'll see how brave I feel when my BF 2142 patch download finsihes. Its no easy job, have to remove the mobo and my Scythe Infinity.

Well, if you're sober enough to be asking the question you're not drunk enough...

First do no harm or something like that?

All done, went smoothly, a very tight squeeze with the Scythe but seems to be seated nice and firmly.

Will see if it has any effect on my overclock in the morning.

Edit - the thermal pad Asus use on the stock sink is horrible, its really thick and hard to remove. I had to resort to scraping with a screwdriver (without scratching the core) and then dissolving the rest with the most alcoholic thing I had to hand (mouthwash :eek: ). Cleaned it all off in the end though and gave it a nice coating of AS5.

Will sort pics in the morning :)

Well its morning Dave, so how'd it go :D
 
It sounds like theres a lot to be said for reseating the stock heatsink. A real clump of paste wouldnt transfer half as well as a thin layer of something better would it. Just wondering if the NB is really pivotal or not
 
Has anyone got their P5N-E do go to sleep correctly? I'm using Vista and when I try and put it to sleep it seems to but as soon as the screen goes black it fires up again back into Vista.

Any ideas?
 
I just put it into standby ok. Im on winxp does it have sleep, not sure how to do hibernate.
Do you have to enable shutdown on the network card maybe since that'll have constant traffic

Definately, the stuff Asus has used is far from optimal.

Its is if you want to hit higher FSB's ie with a E6300. Ive currently got my NB setting at its max (1.7something volts) with a 92mm Amber blowing across. Temps using my fan controller are higher than that hit by the mem of my 7800gtx but not by much. With summer round the corner i want at least 10C shaved off the NB temps.

I've got a tuniq cooling my CPU, so I have a feeling that i'm not going to be able to get a decent sized northbridge cooler on too, except maybe one of those more expensive L-Shaped Jing-Ting heatsinks...

I've got the northbridge on the 2nd highest voltage and have a 92 mm fan situated above the northbridge via a zalman bracket and i'm pretty happy with the temps, can happily leave my finger on the northbridge heatsink without burning it. I've got a pic of the setup in this post: http://forums.overclockers.co.uk/showpost.php?p=8683244&postcount=478.

I haven't tried the highest voltage for the northbridge yet, but I have a feeling i'll need more than just my little fan blowing down onto the stock heatsink. I've got the overclock up to a stable 3.3 GHz so far (on my E6300), but if I want to push it further i'll no doubt have to up the nb voltage. What do you guys think? Any heatsink suggestions? I think I may well need to move the graphics card down a slot too, might be an idea anyway to improve the airflow down onto the nb heatsink for now.
