Hi

Had my CPU a few years now and always hit a bit of a wall with overclocking it.

I managed to get very good mileage out of the FSB but no matter what I try on the multiplier it just wont budge above the default 16.

CPU-Z shot below, any tips welcome, would prefer not to up voltage if poss as worried about temps.

Post a screenshot using the latest CPU-Z.

What motherboard, memory and PSU do you have? What cooling?

cheers, andy
 
Asus Crosshair V Formula BIOS 1703
Corsair Vengeance Arctic White 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz @ 936.5MHz 10-12-11-28
Sapphire 950W PSU
Noctua NH-D14 Dual Radiator CPU Cooler

Thanks
 
Have you turned off CnQ?

I have an almost exact setup in the other room and will fire it up tomorrow and have a look at my own settings.

If you want to get higher than your current 4.5GHz you will probably have to use more voltage but this is fine given your cooler. What are you using to change your overclock settings?

If you change the multiplier in the bios, does it just not recognize the multiplier has changed or will it try to boot up, restart then boot up with stock settings?
 
Yeah I turned off all that stuff and don't have the cpu turning down when idle.

It will post and I can get to windows but it will just not be stable in benches or games and reboots itself after a while.

I could put some extra juice through it but am a bit paranoid about temps cause I know these processors have a low temp tolerance of only like 65 degrees or so.

Just seems to be a bit of an odd chip, other than the default fsb it was only stable at 280!
 
They don't have a low temperature tolerance, they have the same as most other modern CPUs, it is just the monitoring of the temperatures are off at safe levels. They made the temperature sensors in a way that as it approaches its absolute thermal limit, the sensor is more accurate. For clocking and normal use, bellow 61 would be ideal but that 61 wont be 61 degrees but rather much higher, it will just show as 61 due to off temp readings at safe temps. With your cooler it will probably give a temp near or bellow ambient when it is idle because of these sensors.

I would use Core Temp to measure things and just keep them bellow 65 under max load. With your cooler, you could quite comfortably put 1.45+ volts.

Your voltage is quite low, so it doesnt surprise me that your clocks are not stable when you increase the multiplier.

Try 1.4Volts to start and put the multiplier on 20 and FSB back to 200 and see if that is stable.
 
Put the volts up to 1.425 but wouldn't post with higher multiplier. Guess I will have to make do.

Thanks anyway.
