Phenom II X6 1090t OC: results question

[neon4]

Hello people,
I've managed to stable OC my CPU from 3.2 to 4.0

This is the first time I OCed this rig (also first time in UEFI) and I'd like to ask if there is anything I forgot to do, like if there is anything I forgot to increase, change etc.
Also I'd like to push it to 4.2 Ghz, what do you think would be the necessary changes for that? To make it run smoothly.
Thanks in advance for your answers!

Looks like it's been a while since you posted and have since received no response, don't know if you're still asking or not but I will respond anyway.
As an owner of an x6 1090t, I would say that with your current voltage, you should be fine to jump on up to 4.2GHz, assuming your cooling is reasonable, and seen as you're hitting 51 degrees under max load, you should be fine.

If, of course, you're crashing at 4.2, check if its temps or voltage, although I wouldn't want to go much higher than what your voltage is already set at.
I would recommend, however that you do go ahead and continue to push the clock speed on your NB higher. It is said that 2.8 and 3Ghz is the sweet spot for best performance. You're voltage will definitely have to increase though for this to happen, I believe 1.15 is stock and you're already running at 1.16, I imagine you'll have to push on up to 1.2v (I have to run at 1.3v for 2.8 🙁 ) although I may have just gotten a not so overclockable chip.

You may also find this useful if you have not yet come across it:

If you scroll down to almost the centre of the page there are results for best overclocks with the best NB speeds to go with it, although it does say that 2.8 GHz outperforms a lot.

My other recommendation is that your Hypertransport link speed (should you not choose to overclock your NB) should be slower than your NB lane speed (to be on the safe side). But never higher!!!!!!!
They say equal to or slower than NB but I'd recommend a few hundered MHz slower, else you will begin experiencing problems (sync problems I believe).

For the 1090t chips, performance boosts with the NB are much better than those that you will notice with the HT link, so stick your efforts into there.

Happy overclocking!
