I have had installed this kit since 3 months ago when I did a major overhaul of my system by going mini-ITX. An issue came out since that upgrade, the dreaded display driver not responding error :pt1cable:. Which happened every 3-4 hours but recovered instantly. My computer works almost the whole day. Which is insanely frustrating when doing a raid in wow while in a support role.

Some days ago the display started to go black completely with my GFX fan at 100%. Only a cold start would mitigate the issue for it to come back in 15-20 minutes. I did an under clock and 10% raise in voltage, it worked for the next 2-3 days only.

I tested the card on another build, where it ran flawlessly :sarcastic:. I haven't put it back in since. On the iGFX the first problem persists, today it has been reduced to flickers. Thus I am now in detective mode to find the backstabber in the system.

Previous System Specs where it all worked;
Intel Core i3 2100
ASRock B75M Pro
2x4GB Kingston ValueRAM
XFX HD6950 1GB
1x 60GB Kingston V+200
1x 1TB Cavier Green
1x 500GB Cavier Green
Antec Earthwatts 500W
Antec Mini P180

Current System
Intel Core i3 2100
ASRock Z77E-ITX
2x4GB G.Skill Ripjaws Z 2133MHz CL11
XFX HD6950 1GB
1x 60GB Kingston V+200
1x 2TB Cavier Red
Corsair HX520W
Corsair H55
CoolerMaster Elite 130

Please, if you may, provide me recommended voltage and latency settings to be done in the BIOS with this kit so that it may remain stable during heaviest loads. The memtest also passes without issues. Its running with the XMP profile for 2133MHz but I found the voltage to be 1.61 instead of the defined 1.6 in the profile. Also there are two XMP profiles defined, one for [1066MHz, tC 1T] and the other for [1067MHz, tC 2T], why?
 
The setting with the 2T should be profile 1, and with the 1T profile 2 (profile 2 is normally more of a enthusiasts setting...real question is what is the DRAM currently running at? Look in CPU-Z in the memory tab and let us know what the frequency, CL, tRCD, tRP, tRAS, tRFC, and CR are showing
 
@spooky2th

I have done the research on standard specifications. I am asking, if they may require adjustment still.

@Tradesman1

tCL 11
tRCD 11
tRP 11
tRAS 30
CR 2T

Voltages from ASRock extreme tuner
DRAM 1.6V
VCCSA 0.928V
 
Activate profile1, set multiplier to 2133 and I bet the sticks will be set up automatically to the advertised timings & voltage, the optimal settings for your comp/MB & CPU.

EDIT:
If voltage is not correct, it is simple enough to set it up to 1.6V. It will and can vary some. If it shows up as 1.61V, there's nothing to worry about.
 
As stated in the first post, it is running at 2133 correctly with 1066.5 frequency.
I just needed to know whether a further offset would be required to the DRAM, NB or VCCSA voltages for it to be perfectly stable?
Also I needed to know which profile is better, the one with Command rate 1T or the other with 2T?

I will soon be upgrading to a 3rd gen i5 K-series (I plan to run it with a light overclock as well, possibly a little above 4GHz).
 
It seems that even setting the CR 1T in the BIOS doesn't do anything. The applied setting remains at 2T. Even the two XMP profiles in the BIOS have the same CR of 2T. And I have searched over the internet and it seems that it may introduce errors in certain configurations.

Thanks anyway for the help.
