Hi everyone!
I had purchased a new rig back in Oct 2012 after consulting on tomshardware.com (Thread : http://goo.gl/r3abb).
I have Following config:
Mobo: P8Z77 M Pro
CPU: Intel i5 3570K
RAM: 2 X 4GB G.Skill RipJaws 1600Mhz
PSU: Corsair 600W Builder series
GPU: Asus AMD/ATI 7970HD DirectCII 3GB

And some other components with Windows 8 Pro.

I am facing a weird problem from last 10 days when I had cleaned my system.
Sometimes I power up the system it does not give any display at all and shows DRAM_LED blinking red on Mobo. My RAM is in Dual Channel Configuration. But if I remove one of the RAM's it again starts normally without any problem.

But if I install the removed RAM in the slot next to installed one in single channel the system starts normally. Both the RAMs works individually in all slots and also in single channel.

Also many a times they work in Dual Channel too, but its merely luck. I even updated to latest BIOS but no luck.

I am totally unable to understand what's going on. Please Help me out!!

A pair of RJs in 1600, OK can you provide the model #, there are a few different ones, so I can see, in the meantime, if a power surge or something may have lost settings, try installing in 1-3, enable XMP and select Profile 1, then give it a try

I am just going to do that but want to know if it will be an overclocking?
Because its mentioned on few websites that you should not change VCCSA, it should be fixed!!

It's perfectly fine, this is the System Agent Voltage and it is OK to up it, not to far though most don't understand it...Asus in particular is expanding on it as they now have incorporated the MC (memory controller voltage in with it, while most other mobo makers continue to keep it separate, most commonly called the CPUVTT with Ivy Bridge and VCCIO with Sandy Bridge. It's often used to help stabilize DRAM

Hi i am not using any aftermarket coolers for cpu.
I tried the xmp mode and raised the voltage to 1.550 from 1.500, but in vccsa there are only two options either auto or +.10v. So left it at auto and restated the system with RAMs in 1-3 position. But the system went only upto windows 8 loading screen for about 10 seconds or more and abruptly went off. Which happens mostly in dual channel mode.

I would Pull the gpu and see if the sstem acts fine with onboard gpu. I ado check for any mb bios updates. I would also reseat all your cables and see if there any loss hard drive cables. I would check for dust shorts in the pic slots and bent pins or screw under the mb or the mb shield shorting the system out. I would also make a hirem boot cd and scan for a virus and see if your system reboots using the mini xp on hirem boot cd.

Still the same results. I can't just understand that this had never happened in last ten months and now suddenly. Yesterday night it was working on dual channel without xmp perfectly fine but all of a sudden today morning when I powered it on it started giving me problems.

The problem only started when I pulled out each and every part to clean the system. I am downloading the hirem boot cd already to check for all errors. But the thing is that the system works perfect and even for 10 hours continuous if in single channel mode. Also it was working perfectly fine for last two days in dual channel 1-3 mode. So i think that there is no problem with the GPU.

Here is the test report from Intel Processor Diagnostic Tool which says PASS.
