Thanks for testing. Something happed between release 66 and 69.
Looks like 66 is the fastest. but the clocks are higher.

lyra2v2:
release 66: 9805
gtx 970 (core 1354Mhz, mem 1502MHz)

release 69: 9282
gtx 970 (core 1328.5Mhz, mem 1502MHz)

release 73: 9204
gtx 970 (core 1328.5Mhz, mem 1502MHz)

release 74: 9550
gtx 970 (core 1316.3Mhz, mem 1502MHz)

I have tested some more. Release 74 is using more power and heat, so the card trottle and performance is lost.
My test was conducted in a closed case rig with a EVGA superclocked card (2x 6pins power)

but my dev card:
The gigabyte 970oc G1 comes with 1x8 pin and 1x6 pin and doesn't trottle and give bether performance in release 74 than 66.
