AIDA64 Extreme Edition TestsAIDA64 Extreme Edition is the evolution of Lavalys' "Everest Ultimate Edition". Hungarian developer FinalWire acquired the rights to Everest in late November 2010, and renamed the product "AIDA64". The Everest product was discontinued and FinalWire is offering 1-year license keys to those with active Everest keys. AIDA64 is a full 64-bit benchmark and test suite utilizing MMX, 3DNow! and SSE instruction set extensions, and will scale up to 32 processor cores. An enhanced 64-bit System Stability Test module is also available to stress the whole system to its limits. For legacy processors all benchmarks and the System Stability Test are available in 32-bit versions as well. Additionally, AIDA64 adds new hardware to its database, including 300 solid-state drives. On top of the usual ATA auto-detect information the new SSD database enables AIDA64 to display flash memory type, controller model, physical dimensions, and data transfer performance data. AIDA64 v1.00 also implements SSD-specific SMART disk health information for Indilinx, Intel, JMicron, Samsung, and SandForce controllers. All of the benchmarks used in this test- Queen, Photoworxx, ZLib, hash, and AES- rely on basic x86 instructions, and consume very little system memory while also being aware of Hyper-Threading, multi-processors, and multi-core processors. Of all the tests in this review, AIDA64 is the one that best isolates the processor's performance from the rest of the system. While this is useful in that it more directly compares processor performance, readers should remember that virtually no "real world" programs will mirror these results. 
The Queen and Photoworxx tests are synthetic benchmarks that iterate the function many times and over-exaggerate what the real-world performance would be like. The Queen benchmark focuses on the branch prediction capabilities and misprediction penalties of the CPU. It does this by finding possible solutions to the classic queen problem on a chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores. Like the Queen benchmark, the Photoworxx tests for penalties against pipeline architecture. The synthetic Photoworxx benchmark stresses the integer arithmetic and multiplication execution units of the CPU and also the memory subsystem. Due to the fact that this test performs high memory read/write traffic, it cannot effectively scale in situations where more than two processing threads are used, so quad-core processors with Hyper-Threading have no real advantage. The AIDIA64 Photoworxx benchmark performs the following tasks on a very large RGB image:
The MSI Z77A-GD65 posts Queen and PhotoWorxx scores that are about 8% and 4% below those of the ASUS P8Z68V-Pro. This is a trend we'll see through most of the tests, but it's not unexpected: vendors often take several months to fine-tune their BIOSs for the best performance from new motherboards and processors. Over time I expect the scores of these boards would be virtually equal. 
Similar results in the ZLIB and Hash tests... ...but virtual parity in the AES test. Surprisingly, overclocking doesn't significantly help scores here, with my manual overclock providing only a 3% improvement. 
Let's move on to the PCMark Vantage benchmark.

I try OC but when Windows starts up, my computer just stops in the loading Screen for windows....
Same if i use OC-genie
And sometimes it appear a2 in right bottom corner on the screen (rest is black)
My computer specs:
I7-3770K Intel prosessor
MSI z77a-gd65 motherboard
H100 cpu cooling (corsair)
12GB ram Dominator GT / ram fan (corsair)
MSI hd r6800 series HAWK
And i got a H2Go case from MountainMods.com
Im crossing my fingers :P
1. This is true of ANY Z67/Z68/Z77 motherboard except high-end boards with PLX chips. You've only got 16 PCI-E lanes from the CPU, so provisioning 2 x16 slots is impossible without extra hardware.
2. If you're using an Ivy Bridge chip, you've got PCI-E 3.0 lanes with twice the bandwidth as PCI-E 2.0 lanes, so those two x8 slots are the equivalent of two x16 slots if you're using a PCI-E 3.0 compliant graphics card.
3. But even if you're running Sandy Bridge CPU and older graphics cards, guess what? Nothing out there saturates 8 PCI-E lanes anyway, so games won't play one FPS slower on a 2x8 SLI or Crossfire system than they would on a 2x16 system.
But if you want to spend extra money, yes, there are many LGA1155 motherboard that can supply 2x16: ASUS Maximum V Extreme, ASUS P8Z77-WS, ASUS P8Z77-V Premium; EVGA Z77 FTW. MSI doesn't seem to have any boards like this, but again, unless you're running triple or quad cards, you don't really need a board with a PLX chip.
