A8N SLI Deluxe voltage problem

Amp34 · 19 Aug 2006 at 21:03

I have just been playing around with the OC'ing options on this board and have hit a snag. My x2 4400 has been running at 2.3Ghz for the last few months on stock volts and today I tried to up it to a higher speed. The problem is when I put the voltage over 1.425 CPU-Z (and asus probe) show the voltage as 1.40 and when I try running super pi I get an error as soon as it starts.

The highest I can get is 11x220 or 2.42Ghz at 1.425v with a temp at load of less than 50c. I am sure it ca go higher if the voltage was actually what I set it to. :confused:

Ram is on a divider of 333mhz so thats not a problem and I am running a Antec 430W PSU with 2 HDDs and a 6800GT

I found the voltage on this board seems to move about a bit, i set it to 1.4 and it reports 1.44 most of the time.

Tried a bios update?
It took them at least 10 bios's to make that board actually work.

Early A8N bios had voltage problems with x2s. I have the premium version and the first bios to support x2s had two effective options i.e. 1.35v and 1.45v. The current BIOS are better.

Damn mods moving the thread, no wonder i couldnt find it!

I'm using Bios 1011 at the moment, one of the earlier ones, it has voltage settings for every 0.25 volts from about 1-2v. I'll have a go at updating to the latest bios then and see if that helps. At the moment according to Asus the voltage is jumping from 1.408 to 1.424 randomly lol although it doesnt seem to be usetting the computer.

I think it took until something like 1019 before that bios actually worked.

I spent at least 6 months waiting for a working bios from them, in fact thats the reason i joined the forums, because the bios that the board shipped with wouldn't boot with a sata drive or something, and caused games to crash and various other problems that made it unusable.
Basically it didn't work for a very long time and it took at least 6 months before it worked properly.

And as if that wasn't enough, most of them shipped with the older rubbishy chipset coolers that either died or simply couldn't cope with the heat, and couldn't really be replaced because they were under the graphics card.

Horrible board. Works ok now tho, and i recently upgraded it to a dual core cpu and overclocked it and the voltage is fine. I forget what bios i'm running tho but its a fairly recent one.

At the mo the latest one on their website is 1016. Could you explain how I actually flash the bios on this board as I dont have the instruction manual and it doesn't say how to do it to this board on their website?

Thanks

Ok well I have finally managed to update the BIOS to 1016. I now look in asusprobe and CPU-Z and it shows the voltage fluctuating from 1.456 to about 1.480 every so often. I am assuming thats normal even though I set the voltage in the bios to 1.425 should I trust the bios or Ausuprobe for voltages?

Whats the highest everyday voltage people would reccomend for a 4400?

I have my A8N/ X2 4400+ set at 1.425v which gives about 1.44v in asusprobe. It is good enough to give a stable 2.65Ghz (11*241)

Most people like to keep it under 1.6, so 1.55 to be safe. 1.6 is the lowest voltage thats been known to kill a cpu. It really depends on how long to want to keep it for and how good your cooling is.

Does anyone know where i can find information as to where i can measure the voltage using a voltmeter on the board so i can see what the voltage actually is? I assume this wont damage the board and I should do it when it is running?
