Hi,
As an overclocking newbie, I was hoping to share my first overclocking attempts and results and hopefully get some advice from the more knowledgeable folks.
Here is my rig -
i5-750
Gigabyte GA-P55-UD3 motherboard
Kingston 4gb 1333mhz DDR3 memory
Nvidia GTX 260 GPU (stock clocks for now)
Prolimatech Megahalems CPU cooler
CM HAF-922 case.
Windows 7 Home Premium OS
Antec 750w TruePower PSU
2 * Seagate Barracuda 500gb hard drives
After an evening of tweaking and testing this is where I got to -
Base Clock - 200mhz
CPU Multiplier - 20
Memory Multiplier - 6
QPI Multiplier - 32
CPU Frequency - 4.0Ghz
QPI Frequency - 6.4Ghz
Memory Frequency - 1200Mhz
I didn't play around with voltages much, but HW Monitor and CPU-Z after a bunch of tests reported the following max voltages -
vcore - 1.36v
dram - 1.57v
I ran Prime95 for about 25 minutes before failure on one core, running "In-place large FFTs".
I also ran the following tests (all at 1600 * 900) -
3DMark06:
Overall - 19,731
CPU - 6,135
SM2.0 - 8,269
HDR/SM3.0 - 8,356
3DCMarkVantage:
Ran full suite of tests at 1600 * 900
CPU - 51,080
GPU - 10,645
Crysis Benchmark:
1600 * 900, Very High, No AA - Average 30.4 FPS
1600 * 900, Very High, 4 X AA - Average 25.3 FPS
1600 * 900, Very High, 8 X AA - Average 20.9 FPS
Maximum temps during all benchmarks maxed at 64 C or 147 F using HW Monitor (while running Prime95 obviously)
Under normal usage, temps sit around 36-40 C.
Aside from the not so great Prime95 runs, system runs stable and all other benchmarks reported improvements at each step all the way to 4.0Ghz. My rig doesn't seem that stable with Prime95 even running stock clocks, although I found i got much better stability once I enabled "load line calibration" and set memory "performance enhance" to standard.
My question is this - Am I doing ok? and more importantly does 4.0Ghz seem a good safe everyday overclock with my hardware and recorded results?
I am hoping to get a good base setup before looking at overclocking the GPU.
Thanks for any help and guidance.
