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 -115°C to -120°C the whole time... Made it back to -130°C or so in single channel, but it wasn't always consistent (sometimes it would hard lock at -125°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 -110°C triple channel, -135*°C dual channel, -150°C to full pot single channel. Chip seems strong... It can do Geekbench in triple channel at -110°C at 5.9GHz. Dual channel at -120°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?

Gunslinger Posted January 15, 2016 Share Posted January 15, 2016 Seems to me all the good chips of this gen ran full pot, usually in dual channel PLL volts seem to jog my memory for helping them run colder, but platform feels like ages ago, and my memory isn't what it used to be in my youth.

xxbassplayerxx Posted January 15, 2016 Author Share Posted January 15, 2016 Shame. It seems like you have to get lucky and find a chip with a strong core and a low CB Quote Link to comment Share on other sites More sharing options...

xxbassplayerxx Posted January 15, 2016 Author Share Posted January 15, 2016 I had one retail that could run full pot.... Trying to track it back down lol. Quote Link to comment Share on other sites More sharing options...
