Finally got the XSPC RAZOR R9 290X put together - Card is a Gigabyte R9 290X with Alpida vRam and I'm using a QNIX 2560x1440 Display presently at 60Hz.
I believe I'm first to post an over 3000 Valley Score with an Single GPU AMD card in this forum ;o)
My best score is 3066 with TRIXX set at 1258-1500-162-50.
I get a 3057 score with TRIXX set at 1250-1500-156-50 and a 3022 score with TRIXX set at 1230-1500-143-50 = the sweat spot for daily use.
GPU Temps vary from 32C at Idle and Maxs at 47C running the TRIXX 1258-1500-162-50 profile. VRM Temp Maxes at 73C with that profile.
I running the PWM GPU Header to 2 Noctua PWM NF-A14's pulling through a 280x60x140 rad with a custom fan profile in TRIXX on a single loop for now as the i7 2700K is cooled with a Corsair H110. I'm also running a Koolance RP-401x2 with a single PMP-400 pump at 12v. I will post PIC's of the rig in my "XSPC RAZOR R9 290X" thread some time later this week. Case is a Fractal Design ARC Midi R2.
