I then increased to 1.40v and actually got logged into Windows. I started my Orthos test, but blue screened before it ran 2 minutes. It would appear my multiplier threshold is 15.5x, so I'm not sure if I'm done at this point then or not. Should I start trying to increase the reference clock now?
Rbeal, trying dropping the multiplier and increasing the HTT. How is your memory at the moment?

Good luck

HTT is the same as the reference clock, correct? I will start increasing that when I get home. Should I leave the multiplier at 15.5x where it seems to be stable, or should I lower it even further?

When you ask how the memory is, what do you mean? I have not changed any memory settings whatsoever, so as far as I know, the memory should be fine. Is there something I should be doing as far as memory settings go?

Thanks again.

The memory references the CPU speed when calculating its speed, so an overclocked CPU usually means overclocked memory.

Memory speed = (CPU speed)/divider

You can increase the divider if you don't want your memory to be overclocked, however there is no "divider" option in the BIOS. Two things effect the divider: Memory setting (i.e. DDR2 800, 667, 533, etc) and CPU multiplier. You can read more about it here.

Just keep an eye on the memory's speed and timings under the memory tab in CPU-Z. If it's overclocked, then you might want to consider increasing the divider by lowering the memory setting, such as switching it from DDR2 800 to DDR2 667 for example. It's fine to overclock your memory, but if both it AND the CPU are overclocked, it's hard to know which one is causing the instability. So underclock it for now, find the max of your CPU, then we can bring in the memory.

EDIT: And yes, when thlnk3r and many others talk about the HTT, they're referring to the reference clock. AMD did a bad job of standardizing names for the various settings, it can be confusing I know.

Well, it looks like 3.1ghz may very well be my limit. I underclocked the memory(DDR 667) to make sure that was not causing me any issues. With a 15.5x multiplier(3.1ghz) and 1.35v, I increased the HTT to 205. The Orthos test failed. I'm not really sure there is anything left for me to try. Thanks for the help!

Rbeal, would you mind posting CPU-Z screenshots at 3.1Ghz? Perhaps maybe there is a setting or two that you can adjust for more stability/higher oc

Let us know

Good luck

My CPU-Z screens look exactly the same now as the ones I posted on page 1. I pretty much right back at the beginning, where the only thing I have changed at this point is the multiplier. Let me know if you think there is anything else I can try. Thanks again for all the help!

Rbeal, try dropping the cpu multiplier down a couple notches and raising the HTT. For example: 14x * 220HTT = 3220Mhz. Give that a shot and see if it's Orthos stable. Remember to keep an eye on your memory frequency. When you start raising the HTT your memory frequency will also go up and that might cause stability issues.

Good luck
