rorey,
Yes and no. 1600Mhz ram often SPD detects at 1333Mhz but can have profiles in JEDEC chips for 1600Mhz operation. However, this is not guaranteed as it depends on the chips being used.
Your Kingston RAM appears to be fixed at 1600Mhz (default):
• JEDEC standard 1.5V (1.425V ~1.575V) Power Supply
• VDDQ = 1.5V (1.425V ~ 1.575V)
• 800MHz fCK for 1600Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 11, 10, 9, 8, 7, 6
• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
But supports programmable timings...
PnP JEDEC TIMING PARAMETERS:
• DDR3-1600 CL10-10-10 @1.5V
• DDR3-1333 CL9-9-9 @1.5V
• DDR3-1066 CL7-7-7 @1.5V
In some cases, the RAM can/will work PnP... BUT, If the RAM doesn't work PnP, please try manually setting your timings and voltage to DDR3-1333 CL9-9-9 @1.5V and see if this helps.
