I have an 8GB A-Data DDR3, 1600MHz RAM, 11.11.11.28... making it CAS 11?
I am gonna go for 16GB. I can't find a module, getting options for 2 single chips of 8gb...
Now, is Corsair Vengeance good? Cause i am getting 2 for ~100$ (10,200PKR)
If not, which should i look for. And would they cause a problem, 2 single RAMs?

My MOBO is DH77Kc, Will it accept 1866MHz DDR3 RAM?
And will this MOBO accept dual channel ram kit?

yes Corsair Vengeance is good

2 x 8gb should be fine assuming your motherboard supports it and you have 64bit windows

its actually a better idea to get the 2 matched modules together rather than getting one module the same as the one you have

as even adding a stick of the same ram isnt 100% guaranteed to work

My motherboard is DH77Kc, And i have win7, 64bit, Sp1...
Will this also accept 1866MHz ram?

Your board can run up to 1600mhz.
Memory Types Dual DDR3 1066/1333/1600

Mobo is rated to 1600 as is the CPU, 1866 might be a stretch for a 3470, especially on an Intel made mobo (they didn't spend much time with their BIOSs). 1600 might be best bet, but if 1866 is a good price should be able to run them at 1333 or 1600 with no problem via manual setup

Of the two I'd prob go the 1866/10 - stronger sticks can run them at 1600/9 vs the base 1600/10 or the 1600 set

I think i can't do any overclocking with my Board :(
Can i?
And, Won't the 1866 run like 1600 ones? Both have same CAS latency...
And what do you mean by "stronger sticks can run them at 1600/9 vs the base 1600/10 or the 1600 set" bro?

The 1866/10 would run as 1600/9?
The latency of 1866 is 10...

yes but because you lower the 1866mhz to 1600mhz you can tighten the timings

Just bought Corsair 2x8GB kit... 1866MHz (CMZ16GX3M2A1866C10)
1 thing i found, they're running on 1333MHz?
Here is CPUID stats...
Total Size:
16384 MB
Type:
Dual Channel (128 bit) DDR3-SDRAM
Frequency:
665.1 MHz - Ratio 1:5
Timings:
9-9-9-24-1 (tCAS-tRC-tRP-tRAS-tCR)
Slot #1 Module:
Corsair 8192 MB (DDR3-1337) - XMP 1.3 - P/N: CMZ16GX3M2A1866C10
Slot #2 Module:
Corsair 8192 MB (DDR3-1337) - XMP 1.3 - P/N: CMZ16GX3M2A1866C10

Is this going to happen? Or is there something wrong?

XMP is in BIOS settings? And yes, i have latest BIOS. I had to upgrade it cause old bios couldn't run my G1 970...
EDIT: I found an advanced feature in Memory... I chose profile 1...
Whenever i change it, increase it, BIOS crashes...

Right now, CPUID is reading:
DRAM 798.1
FSB : DRAM 1:6
CL 9.0
tRCD 9
tRP 9
tRAS 24
tRFC 200
tRRD 4
tWTR 5
tRTP 5
tWR 10
tRC 40
tFAW 20
CR 2T
Host clock freq = 100
Memory Multiplier = 12
Volts = 1.5000

bIOS IS SHOWING mEM @ 1600, BUT ITS NOT...
