FYI, I usually get 30L for a session lol. That lasts about 6-10 hours depending on how much hardware I'm benching and if the CPU/GPU has a CB/CBB or not.
You need to stop benching that 920 tongue.gif, too hot. 30L last me 3-4 sessions 6 hours each.

I don't believe that in the slightest lol. I do switch chips/boards/cards a lot in each session, though. That burns through a lot.

I tried ln2 again last night but cannot push it past 6.4ghz no matter what I do.
This specific cpu can do 5.7ghz at -40C and hit 6ghz at 1.6v around -80c. It has CBB around -140C and I have to raise bclk to boot.

I only tried these settings:
Vcore - 1.6-1.85V
Vccsa - 1.1-1.35V
CPUPLL - 1.9-1.95V

On my motherboard Vccio is associated with Vccsa....

How do you guys set these voltages?

CPU PLL doesn't need to be raised above stock and VCCSA/VCCIO only needs to go around 1.25V if your pushing memory speeds upwards of 2800.

Only thing I can recommend is trying a bit more core volts. To test if 6.4GHz is the highest your chip will go, disable all but one core and try booting at 105x58 (1.8V or so). Once you're in Windows, kick the volts up to 1.90V, raise the multi to 60x and then start pushing BCLK until you find your max.

The numbers are just to illustrate the process. You don't have to use them exactly since most processors have numbers they do and do not like.

Boot lower than max with one core and reasonable voltage. Raise the voltage and clock up close to your max but with a lower BCLK so you still have headroom to clock it up. Then raise BCLK until it crashes pushing F7 to save the CPU-Z dump every time you get a higher clock.

Thanks Bass! I will try it today.
Perhaps I set the PLL too high (>1.9) and that affects the thermal.

pll has a big effect on cb/cbb ive had a few chips and they all like something diffrent to work for cold. The one im using now likes 1.75 ive also had one that only likes 1.9 so just find the one that dosent give you problems when you pull the temp all the way down and stay there pll dosent play a huge factor in stabilty.
