Is my i5 overclock safe for long term?

[Rui]

Hi I just finished building an i5 build.

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
ARCTIC COOLING Freezer 7 Pro Rev.2
MSI P55-GD80
(don't think the other components matter that much but if they do I will post them too)

I have the system overclocked to 3.6ghz

For the BIOS settings I have:

Intel EIST - Disabled
C1E Support - Disabled
BCLK - 200
OC stepping - Disabled
CPU Ratio - 18
For memory I have them set at stock settings of 7-8-7-24 timings
Memory ratio 4 = 1600MHz
QPI ratio at the lowest (16) = 6400MHz
Load-Line Calibration - Enabled
CPU Voltage 1.250V
CPU VTT - 1.126V
DRAM 1.650
Spread Spectrum - Disabled
Everything else is auto setting for my motherboard

I have run 8 hrs of Prime95 small ffs - no errors
20 passes of IntelBurnTest with 2gig memory setting- no errors
10 passes of Linx - no errors

Ambient temp around 24C
Idle Temps around 32C-35C
100% load from IBT and Linx brings CPUS to a max of 62C once or twice during tests

Is this overclock safe to last for say 4 years? or will this decrease the life of the CPU significantly?

Thanks for the help!

On Another note, I have tried lowering the OC to 3.2Ghz and keeping turbo boost enabled, and my RAM in BIOS says 1600, but in CPUz only says 2569.5, Same thing if I disable turboboost. I don't have this problem with my 3.6ghz OC. Anyone know why this is?

I set my i5 at 180x20 for CPU and 180x8 for RAM so that I can stay within the maximum Vtt(1.155V) and Vram(1.575V). The absolute maximum for Vtt and Vram are 1.21V and 1.65V which should be fine but can potentially wear out your CPU and MB faster according to Intel's datasheet.

If there is a RAM Ocing option as Gigabyte in your m/b, set it to OFF/Standard to have your RAM run at specified frequency.
