I'm attempting to run my cpu at a constant overclock by upping the multi to 13 thus running the system at 2600MHz speed akin to the fx55. I've been able to do this in the past though it never was particularly stable for lengthy periods of time and I'm posting here in the hope that some of you overclocking enthusiasts can give me some advice. :)

What I've been doing is upping the multi from the default 12 to 13 as mentioned above then testing with volts from 1.5 upwards. 1.5 is obviously too low and the computer will hang/reboot, I then up the volts one step at a time and with each step the cpu has more stability (runs through more of 3dmark before dropping to the desktop). My problem is once I hit 1.575 my system refuses to boot and I have to reset the bios manually via the jumper on the board itself. This is the closest my mobo has to the 1.535 stock cpu volts the fx55 has I believe.

System details in sig, psu Enermax Noisetaker ATX 12V Ver. 2.0 470W.

Any advice would be greatly appreciated.
 
Sounds strange, would have thought that chip would have managed a 200MHz overclock without much problems. You certainly seem to be doing everything right.

Mine had exactly the same problem, I would have random reboots while playing games, the ram I'm using at the moment tops out at 217mhz hence my 2.6ghz, if I slacked the timings of the memory would probally do more but not that bothered really as I'm upgrading to conroe very soon. The unlocked multiplier is a total gimick unless I need to do something else.

This link gives some useful info on overclocking an FX-53 http://www.nogodforme.com/MyBabyTera.htm

Sell the FX53 & buy an AMD 4000+ the current ones are capable of 3ghz.

Try changing the multiplier to 13 but dropping the FSB to 185MHz, then start increasing it by 5MHz at a time and see how far it goes.

Thanks for the suggestions.

After some more testing tonight, it seems to be the max this cpu will allow windows to boot at is ~1.56v. 3dm05 drops to desktop at the same point of test 3 every time at that max bootable voltage and this bios won't seem to let me drop below 200 fsb either, ouch.

Guess I have an excuse to buy a new cpu in the near future. ;)
