Yeah your memory clock is beastly, but I might try and lower the memory clock to around 4050/8100 and see if that gives you more room to push the core higher. Its been noted that core clock does more for your score so you might pick up some points. As for the CPU speed reading it always lists...
Set the preset to Custom and you should see the tessellation option appear. The first page can give you more info. The F12 works but it saves to Heaven folder under your "User Name" folder
It looks like you need to turn on the Tessellation setting and set it to extreme for it to compare to the scores here. Also, a screenshot (F12) is required in the benchmark to be listed. Stock clocks should score about 1300 with the proper benchmark settings.
I used a custom vbios to extend my TDP and voltage limits to nvidia hardware limit on the G1 970. (Hard limit is around 1.31v) Fans on my case were throttled to max. In the end I managed to gain a few extra points by sacrificing some memory clock for core.
I've been working with my G1 980...
Your result indicates that 8X AA was not turned on (note that between 1920x1080 and fullscreen it should say "8xAA")
Average 2x SLI 980 score is about 3500-3100, the best atm is 3704
I used this debacle with the 970 misinformation to facilitate a "Step-Up", if you will, to a 980
EVGA GTX 980 SC ACX2.0
1560/1960
4790k 4.7
Im eyeing 2K but I spent a solid 2 hours and I don't think it'll happen without more voltage. *edit -via hardmod
What he said,
Heaven is very GPU dependent, not that it couldn't be bottle-necked, but the exact performance of your GPU will have a greater impact on your score.
Based on others Id say thats in the 1520-1570 range. Your mem clock is great, but the core clock speed has the greatest effect. 1530mhz would put you in this range based on the charts on page one.
You might try finding out if you are reaching TDP limits, in which case sacrificing mem clock...
