Hey,
I have an:
A8N-Sli which seems to be a popular mobo so i was wondering if any one could help me. For some reason my mobo will only let me up my CPU voltage to 1.5 which is crap really and i would like to go higher.
Do i need to upgrade bios to do this?
If so is there any way to do this without a floppy?
Cheers lecsiy

You get into your BIOS by clicking on the Delete key as soon as you turn on your machine. If you don't know how to get into your BIOS, you had better not start changing things on your own. Get a friend, who knows about BIOS settings, to help you.

no, no im more advanced than that. I can get into bios i overclock and all but thats the problem to overclock i need to up the voltage a bit more than its letting me. As ts capping me at 1.5V and thats not enough.
So i mean any ideas on how to change that setting in the bios!

You haven't listed what BIOS you are currently running on the board.
The latest version for that board is 1014.
Is there any reason you don't want to use the floppy to upgrade the BIOS, it is extremely easy to do via floppy.
Otherwise you should be able to use the Asus updater tool, however that tool sometimes fails to work (I don't know why).
Having said that, it is unlikely that a BIOS upgrade will change the CPU voltage range, as the board is made to work at a certain spec.
Are you sure that the CPU is the limiting factor when pusing the speed up, what tests have you used on the system to see which components fail.

Simple reason i dont want to do it with a floppy is because my flopp drive is severly malfunctioning.
Also the problem is not that the computer freezes it is that when i try and up the CPu voltage the top voltage i can possible go to. Theres just not an option to go higher is 1.5V.I need more for what i want to do.
So any more ideas?
Soryr for being a little inprecise at the beggining.

I presume that you get errors when you are overclocking, as you are already getting fair bit out of a 2.2 CPU, the max stable I've seen on a 3700 is 3.2, it will go higher, but is not stable with any of the usual system checking tools such as Superpi.
The only valid reasoning to up the voltage is to allow the CPU to work harder if you overclock it.
I was just trying to make sure you looked at all the possibilities for the system reaching a max stable overclocking point, rather than just presuming that the CPU must be the bit that was suffering.
If you are getting errors on the PC when you go over a certain level, then you need to test the system to determine exactly where the errors are coming from.
It may not be your CPU that is the problem; it could be the memory or the HTT that is suffering.
You haven't listed what settings you are using on the system, only the CPU speed, so I'm not sure if your using a memory divider, if you've upped the memory voltage, slackened the timings, or what multiplier/voltage you're using on the HTT, as you want to keep that as close to 1000 as possible.
Either way, it looks as though you need to get another floppy drive at some point, and us the Asus updater tool in the interim.

Glad to hear something I said helped someone out, the name sounded familiar.
I've been off the forum for a while, been out the country.
Hopefully now I'll get more time to post here again.

The BIOS I memtioned earlier is incorrect, that was for the a8n-sli not the SE which you have.
The latest BIOS for your board is 0502.
http://support.asus.com/download/download.aspx?SLanguage=en-us&mo...
The easiest way to do it is to look at the EZ flash method.
To use EZ Flash, press "Alt" + "F2" during POST
http://support.asus.com/technicaldocuments/technicaldocuments.asp...
With an FSB of 252.64 you're running your memory at DDR 505 which may be too much especially of you haven't slackened the timings used for DDR400.
I always set my Corsair at 2.75V as standard on Asus boards, as they don't read the spid correctly for some reason.
Obvioulsy if you are oc'ing the memory as well you may need to increase the voltage on that as well, and the default HTT multiplier is x5 so your HTT will be running at 1260 if that wasn't changed to x4.
