Yesterday I, Coolbits, The King and |ron met in Monza, we had 30 litres of LN2 and some stuff to test.

Config:

  • Core i7-980x # 3020A – provided by Coolbits
  • EVGA 760 // bios 74 – provided by AOC
  • HD 4870 1 GB – provided by AOC
  • KHX 2000 cas8 – provided by me
  • P&C 1200 watt – provided by me
  • OS and HD – provided by me
  • Ryba / Sf3d CPU and GPU pot – provided by AOC // great POTs, but I still prefer mine


The main objectives were to do a super-pi 32M, 06 and vantage with our HD4870.
The limit for 32M with 1.83 volt was around 5.7 GHZ, unfortunately we can’t feed the uncore with more than 1.45 volt because of stability issue with higher voltage…then low uncore frequency.
No matter what CPU PLL voltage we use, CBB and CB were both around -125°, not a great CPU.

super-pi 32M // 6.25.812 // 980x @ 5690 MHz // KHX 2k cas8 @ 7-7-6-18

Not that great, but good enough for TOP 100 at 32M.
