xxbassplayerxx Posted January 15, 2016 Share Posted January 15, 2016 (edited) Last night I was tuning my 980X and OC for Geekbench (for an OCN Competition) but I was having issues pushing my CB back. Removing memory sticks didn't seen to help a whole lot... CB stayed pretty near -115Â°C to -120Â°C the whole time... Made it back to -130Â°C or so in single channel, but it wasn't always consistent (sometimes it would hard lock at -125Â°C). Does playing with the skews help move that around? Here are the voltages I was using: VCore - 1.785V QPI/VTT - 1.435V PLL - 1.60V QPI PLL - 1.32V IOH - 1.26V DRAM - 1.86V Clock skews - 800 / 900 All PWM frequency switches were set to max (1 KHz? Can't remember) Here's what I've tried: I lowered my Uncore frequency and lowered QPI/VTT to 1.315V. I tried raising PLL to 1.70V, but haven't tried 1.50V (derp, should have tried that). I tried triple, dual, and single channel memory. In my past experience (with a different chip), this made a significant difference, a la -110Â°C triple channel, -135*Â°C dual channel, -150Â°C to full pot single channel. Chip seems strong... It can do Geekbench in triple channel at -110Â°C at 5.9GHz. Dual channel at -120Â°C and 6GHz. I gave a half-assed attempt at Pi and validation. Validated 6.5 and passed 1M at around 6.15GHz (but didn't beat my previous score, so I didn't save). I'll try 1.50V CPU PLL next time. Any other advice? Should I lower my QPI/VTT even more?
