I know, if I had 2 more blocks I would try. I need to ship out the KPE's before the buyer kills me. He has been really patient. I still need to do some more testing but it seems with this latest revision that the looser timings and higher mem clocks are evening themselves out to the same score. This is just some prelim results and I'm sure there are still tweaks to be made. Either way I was doing firestrike runs at 8000mhz memory last night.
If you are talking about the XOCKPti bios. Yes you can use either program to set your core and mem clocks and power/temp limit. Only use those programs for those settings. Do not check off any voltage boxes or touch the voltage sliders at all. let the evbot do that.
I have only tried it with precision x and have had no problems at all. I would use precision x if you don't have a preference.
