Asus A8n-E Overclocking

[spiral out]

I've been using this board for a couple of years now, and have only just recently tried to up the voltage for the CPU to above 1.4v to see if i can get an overclock higher than 2.7Ghz on my 4200 CPU. But when i put it on 1.4v or above it causes the board to hang. And i have to pull the battery out to reset the bios.

Can this board go above these volts?

I am using bios V1008 could it be this or maybe my power supply which is a couple of years old now. A Nexus 4090?

Could this be caused by the power supply?

well i have the same board and same cpu as you, for roughly about the same time as well. i have recently OC'ed for the first time. everytime i tried to take it past 2.7 though system wouldn't even boot, i thought it was running stable at 2.64 but then my pc randomly restarted allbeit the once but that was enough for me to reduce it back to 2.588 which has given me no problem. incidently i am using a voltage of 1.375. good luck mate.

I never had much luck OCing S939 A64 to 2.7 or above stably. Most I usually get (stock volts) is 2.62-2.66. Thats with a 3200OEM, 3700retail and 3800retail (single cores). motherboards asus a8n-sli-se with RAM timings lowered so they arent the problem. I can drop the CPUs to 2.6 and run them all day long no problems but much over that and they give up sooner rather than later.
I use stock or NorthQ air cooling. Some people get banzai results but with large volts and supercooling.

What rating is your PSU? And what else do u run on the system to draw the power out? Its unlikely tho, it just that the CPU cant handle that frequency. But its still good at 2.6 no? nice free speedup

It's a 400w PSU, Run a couple of samsung hard drives and a X800 GTO overclocked too.

Just wanted to see if i could push it furthur for the fun of it really, I have seen people on here get these chips upto 3Ghz.

What bios version are you using MKA?

[MKA]

My bios is the 1008 version i believe.

I had one and I culd not get the FSB up past 250 reliably...so my 10 multiplier cpu's stopped at 2.5.

Tbh it never really bothered me and all my 939's ran at that. My Opeteron (sold here on HEXUS recently) went much better in a mates 939 mobo, but I still loved my Asus. Within it's happy zone, it was rock

I had no problem lifting an old amd64 4000+ to 3.0ghz on the asus A8N-E though it was a while ago.good board i do miss it lol.

As zak said i had one of these was a rock, better for o verclocking than the current an832 thing have, i got my 144 opteron to 2.8
