Done the basics, now what?

post #1 of 8
Thread Starter 
Hello all. Please be gentle, this is my first post here

I've got the following system:
E6420 with Noctua NH-U12F
Asus P5N-E Sli
Geil 2GB PC6400 DDR2


I've had a read through some basic overclocking guides and have managed to get to 3.1GHz which is 8 hours Orthos stable (small FFT and blend test, both at level 9). For that I had to update my vcore to 1.43V.

This runs at 387.5 x 8, 35C idle and 61C full load under Orthos.

I tried to go to 3.2 at 1.46V but when showing the BIOS splash screen it had artifacts all over it, obviously that scared the **** out of me so I quickly turned the computer off. Rebooted and got into the BIOS (no artifacts this time). And put it back to 3.15 and 1.46V, this gets into windows but locks up soon after.

Where do I go from here?

I'm kinda scared to up the voltage anymore after the last scare, I dont think the problem was temps however as I was under the impression that low 60's is ok, I should only start worrying when it gets to high 60's low 70's. Is this right?

I havn't changed the voltages for my NB either, I've left that set at Auto which I presume is 1.393v as the other options are 1.208, 1.393, 1.563, 1.748. Do I need to change this?

My memory is at stock speeds and I'm running it unlinked at 800FSB, 4-4-4-12. I plan to overclock this later after finding my max cpu speed.


Any advice?
Thanks.

First off... WELCOME!!!

Secondly, click on User CP near the top of the screen and input as much info about your rig as possible.

To answer your question (more like attempt to). If you had artifacts on your BIOS screen then I would think something is really wrong. I never had artifacts on my screen just from overclocking my CPU. Now overclocking the GPU is a different story, but even then I never saw the artifacts on bootup... where it goes through the POST process. I am defenitely no OC'ing expert, but I would definitely wait until someone else on here with your same CPU lets you know how far they went with their's. I can guarantee that someone will be able to help you out on here. This place is great for these kinds of questions!

As for your temps, I think you are correct in saying that high 60's/low 70's is your threshold, but don't take my word for it. I know there was a thread on here somewhere that listed a lot of CPU's and their limits, but I can't remember exactly where I saw it.

Sorry I can't really help you out, but just give it time... someone on here will know exactly what you need to help you out with the fine art of OC'ing!!! Once again, welcome to OCN!

Thanks for the warm welcome

I think I may have to take a backward step as I've had a few problems in the last few hours.

I took my graphics card to give it a quick clean as it was getting a bit hot. Put everything back together and booted back up but just got a blank screen. Turned it off, checked all the wires and one of the power cables to one of the hard drives had fallen out. So i pushed it back in, booted back up again but still nothing.

It goes to the BIOS splash screen, then instead of bringing up the dual boot screen to let me choose which OS to load (xp or vista), there's just a little cursor flashing in the top left of the screen and it doesn't go any further.


I then stuck the XP cd in and ran the repair console and tried chkdsk /r. Completed that and tried to boot up again. This time it booted as normal got into windows, all my data is still there.

But then after about 5 minutes it freezes so I have to restart, and guess what....I get the blank screen again

I ran chkdsk again and before booting reduced it to 3.0GHz and knocked the vcore down to 1.4v. (Which ran for 12 hrs stable in orthos 2 days ago). This worked for about 5 mins before the system froze. I had the temps open at the time, they were around 39C idle so its not overheating.

This time I was able to boot back into windows without running chkdsk again, so I restarted it and knocked it down to 2.8G and 1.36v (which has been stable the last year).

Its been running for about 15 mins so far with no issues, temps are still fine.

Any ideas what's going on?

I'm guessing my overclock is either not stable even though it ran for 8+ hours in Orthos, or I have somehow corrupted my windows install and this is causing the crashes rather than an unstable overclock.

Thanks for any advice.

You might have corrupted your Windows. Once you find a stable OC that you can run for hours upon hours, days upon days... leave it at those settings and reinstall Windows. If that's not too much of a problem then I would reccomend that. It might not be the easiest solution out there, but it always seems to fix my problems.

Go to stock settings. If you're getting spotty performance, then do a clean windows install.

One thing that many people forget/don't know is that you should *never* install windows when OC'd. Just like you should never flash your bios when OC'd.

Your CPU is only rated up to about 60C. I would highly recommend not letting temps exceed 60C.

I'm very, very familiar with your board, and for the kind of OC you're looking at you're going to need 1.56v on the NB. Once you hit FSB's over about 380 the NB needs more voltage. In order to be safe at the voltage, make sure you remove the heatsink from the board and replace the stock TIM with AS5 or something similar, if you haven't done so already. Buying a new cooler for it would be preferable (I use the Thermaltake Extreme Spirit II).

I'm not familiar with the e6420 specifically, but the e6400 should go to 3.2GHz on this board without too much trouble. However, the 650i and 680i chipsets both have FSB holes. They're slightly different on every board, but generally people run into them in the 390 - 450 range. For example, on my board I can post at 400 FSB, but not above 400 until I hit >410, then there's another hole from like 420 to 440 or so. It's usually worth turning your CPU multi down to the minimum possible and putting your vcore up to the max you're willing to tolerate and testing every FSB in the range you're interested in just to see whether that FSB is a theoretical possibility for you.

Also, you should probably take your questions to the dedicated thread for this board You can find it stickied on the top of the Intel Motherboard section.

Thanks for the replies everyone.

It ran for 5 hours last night, some of it spent running orthos, some of it running 3dmark 06. All ran fine. Shut it down last night and the blank screen happening again today.

I've reduced everything to stock speeds to see if that makes a difference, but I'm starting to think that its something to do with my windows install rather than damaged hardware. It just doesn't make sense for it to be hardware related as chkdsk fixes it everytime so I think I'm with you beelzebub.

Is there any way of knowing whether it is simply a corrupted install or whether the disk is actually damaged. I can check it on another hardrive but it will take me a few days to get all the data off it as I'm busy atm.

Thanks for your advice TriBeCa. I dont have any cooling on my northbridge at the minute (apart from the stock heatsink) and I don't really want the hassle of taking it off and putting new bits on, I'm not really confident enough to do that. And thanks for the head up about the 60C, didnt realise it was that low.

Thanks again.

I haven't read over the whole thread but TBH ditch the P5N-E and get a P5E...
the P5N-E has the worst chipset ever for OC...
the P5E has the new X38 chipset which I found incredibly easy to reach max OC..

I would say go with another hard drive just to make sure. It wouldn't hurt to swap it out... it's better to eliminate it then to worry if you have multiple problems. Keep us updated!

by the way... welcome to the wonderful (but sometimes annoying) world of OC'ing! Ha!Ha!
