Guys,

I bought a bundled mobo, memory set from Newegg, got pushed into unfamiliar territory.
I haven't overclocked before. I am not interested in overclocking CPU, but have to oc
memory, since the board's default is DDR3-1600

I've read OC tutorials, think I have a handle on some of the settings I need,
so I'll post the list, but there are still a lot of settings where I'm uncertain,
I haven't found info on them.

G.SKILL Trident specs:
- DDR3 2400 (PC3 19200)
- Timing 10-12-12-31
- Cas Latency 10
- Voltage 1.65V

Pretty sure of these:
Memory Clock Multiplier 1.00
Memory Multiplier 24
CAS# Latency(tCL) 10
RAS# to CAS# Delay(tRCD) 12
Row Precharge Time(tRP) 12
RAS# Active Time(tRAS) 31

Not so sure on these (some of the letters in parenthesis are hard to read
on bios screen, so I might have a few wrong):
Command Mode(tCMD) 1 or 2?
Write Recovery Time(tWR) ?
Row Refresh Cycle Time(tRFC) ?
Active to Active Delay(tRRO) ?
Write to Read Delay(tWTR) ?
Read CAS# Precharge(tRTP) ?
Four Active Window Delay(tFAW)?
Refresh Interval(tREFI) ?
CAS# Write Latency(tCWL) ?
CKE minimum pulse width(tCKE) ?

Motherboard: ECS Golden Z77H2-A2X(1.0) LGA 1155 Intel Z77
CPU: Intel Core i7-3770 Ivy Bridge 3.4GHz (3.9GHz Turbo) LGA 1155 77W
Memory: G.SKILL Trident X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM 2400 (PC3 19200)

Does the board support Xmp mode in the memory section, if you have the option.
It should read the settings of the memory can configure it auto if enabled.

I suggest manually setting to the dimms supplied specs (timings,voltage,and speed) leaving all other timings on auto. See if it works, post back with your results.

I build a PC maybe every 2-3 years, and each time is a learning curve. I read up on xmp profiles, new to me,
and found that yes, the ECS Z77H2-A2X board supports two XMP profiles. Profile 2 did indeed load the settings.
Whew! There was a time delay posting back while chasing down another (unrelated) issue, but with that sorted,
the box runs nicely.

Thanks for the assist!
