Yeah, on a TRUE. I can put it up to 3.85 and be internet stable but fails orthos. What other things do i need to change? My memory is OC'd too...should i put it down?

i get the same problems, mine wont go over 3.6ghz

its @ 3.6 right now (450x8) 1800fsb
post #3 of 24
Super PI is not stable IMHO try 9 hours of PRIME95 and to get higher you will have to adjust your vcore and FSB core voltages. TO change the voltages go into the BIOS to adjust. There is a great thread here on OCN about you mobo and tweaking it
post #4 of 24
Yeah up the Vcore a tad and try again. If that fails you might have to up the RAM voltage if they're linked and your RAM is increasing as your CPU does.

My batch is Q746A518.

I started Orthos testing and it immediately BSOD'd, so i bumped it down to 3.55, and Prime95 is running fine now....its been like ten minutes.

How do i change the vcore though? It shows it but won't let me change it. How?

Need some CPU voltage, maybe some northbridge/FSB voltage too.

Whats your Vcore now? Add +0.025...so if you're at 1.25 try 1.275, or 1.3v or something along those lines.

To change your voltages, in the main menu of the bios, press ctrl+f1. This unlocks the ability to change your ram timings, voltages and everything else you need to finish oc your system. Also, do not take your CPU above 1.3625volts, as that is when it starts to damage the proc.

You and I have pretty much the same setup, so let me know if you have any other questions. Also, check this out for our motherboard:
