Asus P7P55 WS Supercomputer Ram nightmare

I have an Asus p7p55 ws supercomputer motherboard , and some really strange and bad things happened lately, i would want to tell my story, but its long and i don't really know how things work around here..

The thing is, i have been using an i3-560 OC'ed @ 4.2 ghz with 2x2gb Kingston HyperX Black Limited Edition , DDR3 1600 (XMP) 7-8-7-20 latencies.

It worked perfect for more than 1 year, and around 1 month ago, i wanted to get more ram. so far i tried : 2x8gb kingston kvr, 2x8gb kingston hyperx beast 1600, 4x4 kingston hyperx beast. After the system failed to start with each of theese options, i tried getting a kit from the Mobo QVL list, but the same thing happens.

When i insert all the ram, for example 4x4gb, or 3x4gb for the QVL kit(KHX1600C9D3K3/12GX) , the system hangs at POST right before the ram count.. but if i insert just 1 stick, i get blue screen either BAD_POOL_HEADER or IRQ_NOT_LESS_OR_EQUAL.

After many attempts to make it work, voltage increase and decrease, BIOS reset etc.. eventually the CPU crashed, got a BAD BIOS CHECKSUM when turning on the PC, tried another mobo ( P7P55-LX ) same thing there also. I bought a brand new i3-550 , and now i get the same thing.

Memtest doesnt work, it stops less than a second when the test starts, at 17% , 32% and just hangs there. Tried on a brand new Gigabyte GA-P55-UD3L , which also has the 3x4gb kit on its QVL, same thing happens in Memtest, and windows freezez at Starting Windows, just before the 4 colors should appear, instead of the blue screens.

I dont know what to do, i'm desperate, im afraid to get another memory..

Any help would be appreciated.

psu or video card maybe? can't see a new cpu, mb and ram doing the same thing unless those other two items are the problem.

Intel lists i3-560 Memory Specifications as using DDR3-1066/1333. The memory controller is in the CPU. The motherboard QVL may be using a better CPU such as an i5 or i7. It looks like your overclock is failing when you populate more than 2 memory slots with 1600 memory.

Do you have the latest BIOS, if not get that, if you do, the reset the CMOS, install the sticks in the proper slot, go into BIOS, enable XMP, select profile 1, go to DRAM voltage and raise it + 0.05

There's a Gainward GTX580, tested it on other systems as well as the PSU, and anyway the system boots with the old ram. with this graphics card and PSU.

I tought about that Cavin7, thing is , i'm not trying to overclock, not with the new i3-550.. and the system does't work with the auto Dram frequency, which is 1333 by default.

Tradesman1 , i will try and i'll post the result.

Thank you all for your help.

I tried, same thing happens, with 3 sticks.

With 1 or 2 sticks , the sistem hangs at POST.

Damn chipset, it's given me nightmares.

And yes, it has the latest BIOS.
