While felinuz and I were decoding what exactally DDR3 uses for timings I honestally got to thinking what it really is like. Often times people look too closely at the speeds and not the timings themselves... Perhaps we have overlooked what is really going on and are being taken advantage of.
Im going to list several GDDR timings to give a overall impression but I will list the DDR3 for now. Here is what your fancy card is actually using... this may come as a suprise to many:
Samsung GC20
Voltage: 2.0v and 1.8v
Speed: 1000mhz
Timings (CAS-TRP-TRCD-TRAS): 7-6-7-15
Samsung GC16
Voltage: 2.0v and 1.8v
Speed: 1200mhz
Timings (CAS-TRP-TRCD-TRAS): 8-8-9-19
Samsung GC14
Voltage: 1.8v
Speed: 1300mhz
Timings (CAS-TRP-TRCD-TRAS): 9-9-10-22
Samsung GC12
Voltage: 1.8v
Speed: 1400mhz
Timings (CAS-TRP-TRCD-TRAS): 9-10-12-25

Perhaps people need to re-consider their feelings at Rambus's XDR...Because clearly this isnt what I would want to run on my desktop
