One thing has struck me..
is the difference so fokkin huge when in comes to the IMC, and the mem speed from chip to chip..
I have friends running the 4770k + 2800mhz just fine
This 4670K specimen is maxed out at 1600mhz (4gb) 6.6.4
And at 4800mhz only 1333mhz (4gb) 5.5.4
If i bump up the ram speed and voltages and loosed up the timings much ( 2000mhz 7.7.7 or 1866mhz 7.8.7), i get artifacts/freeze and crash, and if i tighten the mem really hard, i get even lower speeds as a result
Its borderline Intel spec..
at stock cpu clock its 1600mhz-1700mhz mem speed max (loose timings)
Please share some light over this..
