ASUS P6T Deluxe bios assistance

post #1 of 7
Thread Starter 
Hi everyone, I'm new. Kind of noobish when it comes to overclocking as well.

I built the following computer just over 2 years ago:

i7 920 @ 2.66GHz
ASUS P6T Deluxe
Corsair Dominator DDR3 1600 (TR3X6G1600C8D) x2 for 12GB total
EVGA GTX260
850w Nexus Silent PSU
Noctua NH-U12P CPU Cooler
Windows 7 Professional x64

I never overclocked it, I just had it setup for all the standard clocks. I think the only adjustment I made was that when I use all "Auto" settings in the BIOS, it wants the RAM to run at a speed of 1066 instead of 1600 for some reason, so I manually set the speed for 1600. It's been running perfectly stable for 2 years with no issues at all. Until about 5 months ago when I accidentally cleared my BIOS settings... D'oh! I had decided to do some housekeeping and reinstall windows, download all the latest asus drivers, etc. While I was at it, I decided to update the BIOS to the latest version, which reset all my settings.

The problem here is that I have no idea what I had them set to in order to make my system work so perfectly before. I've been having random blue-screens/computer resets ever since. I usually get one every couple of days. My best guess is that I might have some setting wrong in the BIOS, like a voltage or something, because when I change the RAM speed from "Auto" (which is 1066) to the preferred 1600 with an 8-8-8-24-2T timings, it wants me to manually key in a bunch of other values and I don't remember what they were previously set to. So, I might as well ask some experts for advice...

What I'm kind of interested in doing is a slight overclock to my system... nothing major. I prefer stability and longevity of my components rather than finding out where they crash and then dialing them back a little. I'm 100% certain I have adequate cooling for a small overclock, but I'm mentally challenged when it comes to understanding all the different settings like how all the different things I can tweak effect each other and I'm worried about causing even more instability than I already have. So, maybe going from 2.66GHz to 3.0GHz? I'm unsure, I've never done this before...

This particular motherboard is supposed to have some kind of automatic overclocking where I can basically flick a switch and it does everything for me, but I'm not sure I trust it. For instance it's detecting my RAM as 1066 9-9-9-something, which just seems silly. Anyone out there able to walk me through what all my BIOS settings should be?

Thanks for any and all help!

My suggestion as your cooler is decent would be to set vcore to 1.30, set multiplier to 21, base clk to 160. Set vqpi to 1.3V, set your memory to 1600, 8-8-8-24, and leave the other memory settings set to auto for now. Vdram to 1.66V

Those voltages should be plenty enough to run that minor overclock. The 160MHz base clock will give you a cpu frequency of 3.36GHz. If you still have bsod problems try raising vqpi or vcore to 1.35V.

However I would suggest reading more and learning more, start by learning how to test for stability by using IBT/linx/prime etc, then just start to push you your frequencies and learn what the roadblock is each time you can't push any faster. A 920 should be able to get close to 4.0GHz easily, and if it's a D0 hit 4.2GHz with a bit of trying.

Thank you, Stren, that is the kind of information I was looking for.

I tried messing with more BIOS settings last night (before reading your post) and mainly tweaking a few things like increasing/decreasing voltages to try and get the 1600 8-8-8-24 timings I was looking for and I had some system instability so I just said "f**k it" and set everything to "Auto" so I could make backups of all my data in case anything goes horribly horribly wrong. So right now I'm running 2.66 cpu and 1066 ram. The good news is so far my computer is stable this way, although the crashes aren't that frequent to begin with.

I'm backing everything up as I type this, and tonight I will mess around with your suggested values and see how it goes.

One other question - I have a pretty good idea how to test for stability (memtest86, furmark, prime95, etc), but can you recommend a good, reliable source of information for people getting started in overclocking? Like, a guide that explains why when I increase my ram speed from 1066 to 1600 that my cpu temp goes up an average of 3 degrees C? I've done some internet searches for info like that in the past, but wasn't sure how trustworthy their info was since nearly every website I found had conflicting info, or info that even in my limited knowledge I knew must be wrong.

Thanks! Once again, I appreciate the help!

Hi Stren,

I tried out the OC you suggested the other day and it seemed to work fine. Check the images below, I added a couple of images of the tuning area of my BIOS so you could get a better look. I also wanted to confirm that I've plugged in the numbers the way you were expecting me to and I didn't put a voltage in the wrong place or something.

I ended up with 3.36GHz exactly like you predicted, and I ran several passes of Passmarks "Burn In Test" (about 30 mins worth) and a couple of passes of 3DMark Vantage. Everything seemed alright, no errors anywhere.

The only concerns I had were:

1) In my BIOS it gives me a warning (you can see it in the pic) that I should not put my DRAM Bus Voltage to anything higher than 1.65, and it even turns the color of it blood red just to make me extra scared. Is this just to stop noobs like myself from messing with things I don't understand, or is there really some danger to this? Is it an overheating issue? In other words, could I jack the voltage up to 1.75 and as long as my CPU is within normal temps it will be totally safe?

2) My temps got much higher than I'm used to seeing. When I'm running with all the BIOS settings on Auto and my CPU is 2.66GHz, my temps generally sit at around 39C when idle, and about 58C when under 100% load for lengthy periods. Which the 3.36GHz overclock my idle temps were about 50C and stayed around 79C when under 100% load. Is this reasonable? Where would my temps have to get to in order for me to be concerned?


Any thoughts?

I was looking around for more info and I found these two really helpful pages. I thought I'd post them for everyone else, too.

Enjoy!

79C at load is okay, I suggest that you do not go over 80C though. You are probably running the stock heat sink / fan assembly (HSF) that came with the CPU. You can install an aftermarket HSF and lower your temps a lot.

The message you are seeing with your dram voltage set to 1.66V is normal, ignore it, but I would not set it higher than 1.66V.

Since your ram is rated at 1.65V why did you set it to 1.66V? 1.66V should be fine, I am just curious.

Hi idahosurge - thanks for the comment on the temps. I was kinda thinking the same thing.

I know this thread may look like a wall of text, but the answers to all your questions are in it.
