every each of us got a different chip. So i guess no one can advise the exact amount of CPU Voltage you need to use to have a stable 4.3ghz. But im not telling you that you're wrong, you can actually use that as your initial margin for trial and error. if it boots up, try to run IBT or Prime 95, if it crash down, adjust again by 0.005 add or subtract until you have a stable OS.
Offset setting is desired because, It just lessen or heighten your default CPU voltage through CPU offset voltage, you dont need to change default voltage. It literally act as a "gate valve" of your CPU.

things i already have>
Case: Storm Enforcer Cooler master
SSD: 512 GB Crucial M4
1 tb Caviar Black
Antec High Current Pro HCP-850W
Like how totally dubbed describe ASUS CS or RMA service, they are the worst. But lucky for me coz ive been using Asus brand since i got my first laptop and never had a problem. That is enough for me to trust this brand so i got this board. I guess my luck is still on this brand coz i never experience any fault with my board. Just my plain experience no fanboy comment.
also: we got Asus service center few minutes away from my place, so i think ill never have a problem with this board. (hope so)

stress test with aida64 for 1 1/2 hrs ( is that long enough)? is it worth just uping the multiplier to 47 leaving the voltage at 1.32v as it is?
can anyone give their veiws on this pls
8hrs of stress test are the standard and 1 1/2 hrs is way below the standard. If you're on 4.6ghz with 1.32v and is stable with a temperature not exceeding 80c then you're ok. I suggest you use Prime95 or Intel Burn test for stress test. Those application will stress and push your chip to the limit in exchange for accurate result. The only reason your chip will be damage using those application is if you got a bad cpu cooler, not properly seated, no thermal paste or not properly applied and your CPU runs hot enough to burn it. So running test even on stock is necessary.
You can determine that you have a properly seated and working perfectly cooler if your CPU temp is close enough or just few Celsius ahead of your room temp. in exemption of course with below zero coolers

I reformated and slowly installed ASUS drivers. apperently some of the drivers are bad and was causing my cmputer to crash.
the rader app was the first one i ran into that casued games to crash.
you can remove and uninstall all asus applications except for necessary drivers. i didn't find them necessary to be honest.

i also seen on youtube a guy called jj from asus saying that aida64 is better for stress testing than prime95 for the ivy bridge cpu's? who do we believe in? which stress program is the right one to use? which is the right progam for telling the right temps for testing
CPU-Z generally tells you your cpu speed on full load, or its capacity. Meaning that your CPU can run 4.6ghz at full speed.
Now with aida 64, it is telling you your CPU running speed in real time. Meaning your CPU's current speed. Possible that it is running with just 5% or less load so very reasonable that you can only see 1600mhz instead of full load speed of 4.6ghz.
Now regarding on which application you will be using on stress test. There are applications that will 100% stress your hardware without exemption or rule, that is a hundred percent you can get accurate result. Some application or "safer" application can stress you CPU to a certain level, once exceeded itll prompt you to discontinue the test even without reaching you hardware's full potential. result can be different from what you should be expecting.
Also, you can try to update your bios. the latest bios upto now is 1708

The only reason your pc will shut down, hangs up, crash or BSOD during stress test is because you're CPU voltage is not supplying enough power to compensate with the load. Solution is to increase your CPU voltage, rerun test, if system still crashing, do the cycle again till it becomes stable.
Also other things to consider is your DRAM voltage, and temperature..
If you over clock and add some value on your CPU voltage, you should do that also on your Dram voltage and GPU (tho i find GPU to be optional, depends on your card).
0.9v at 4.6ghz? i guess this is just the result of cpuid? cpu-z? 0.9v is the lowest value that a CPU can run at full stock under load. So i guess you just over look that value.Edited by SpEaKeRb0xXx - 1/1/13 at 9:57pm
