AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[SergeantNathan]

are you sure about that limit of 10x? then i wouldnt be able to adjust my NB at all, since my bios is very funny. i cant lower it from stock, and i can only raise it at the same rate as my HT link. basically im just short on adjustment options, lol.


also, what do people recommend for testing turbo stability? something that only uses 2-3 cores at a time, without me forcing core affinity.

On the 1055T? Yes, I'm sure. The only way to raise it is with FSB (which starts at 200, then 10 mult =2000 default)

Around the 2400 area (ie ~240fsb) you'll need to start adding "CPU-NB" voltage (not the one labelled "NB Voltage")

Regarding the HT Link: you won't see a benefit in performance beyond stock, but supposedly, for ultimate stability, it's best left in-sync with the NB freq (then again, for ultimate stability, AMD's current implementation of Turbo is best turned off... the proof is in the pudding: my out-of-sync settings are plenty stable), so if you can't modify the multipliers at all, don't sweat it.

So, at your current 257FSB, that means your NB is running at 2570... if you haven't already increased CPU-NB voltage, you need to do so. If you can't, then it's unfortunate, but you'll have to back way off on your OC. Feel free to flip your MB the bird.

As for the CPU frequency: you can generally get 3.6 to 3.7 on stock voltage, so you're fine there, but your turbo is probably giving you problems. Try setting the turbo multiplier to 15.5 for just-under 4GHz. Can't change that multiplier either? Well, then... feel free to flip your MB the bird again. (or just disable turbo... for the love of crap, please tell me your MB at least does THAT. If not, it's back to scaling your OC waaay back so that the Turbo freq is stable)
