(May be a bit of a read)
I'm not exactly a noob at overclocking but I am new to Intel CPUs. I had an AMDX2 5000+ (non black edition) which I clocked to 3GHz perfectly stable. I have since upgraded to Intel and some things are a little different.
My system specs are as followed:
Intel C2D E8500
Thermalright Ultra Extreme
2x2GB OCZ Reapers DDR2 800 (4-4-4-15)
Gigabyte GA-EP45-DS3P
HD3850 256MB (Awaiting delivery of my HD4870 1GB, they didn't have them in stock when I ordered this new setup so it's on pre-order)
1x150GB Raptor
1x640GB WD640
Cooler Master CM690
Before I even installed windows I had a little go at overclocking. I went for 4GHz straight of the mark. I set multiplier to 9.5 (some reason it was set at 9 for default) and I increased the fsb to 421 and increased voltage to 1.3625 (CPUz reports 1.328V). It worked perfectly but had some problems as windows was detecting 3.8GHz and CPUz saying 2.5GHz. Later found out it was due to speedstep so I disabled C1E and EIST and everything worked flawlessy. Ran Prime95 for over 15 hours without a hitch. RAM was running at 1010MHz with default (auto) dividers at 5:6 and I left timings at default of 5-5-5-18.
Today I figured I'd play around a bit more cause I know the CPU is capable of more. But everything I tried simply didn't work with instability issues. I read that the Gigabyte motherboards had problems with high fsb (according to xbitlabs) so I decided to test myself and ran the PC at 8x500 for 4GHz and everything ran like a dream. Tried 9.5x450 for 4.27GHz and it was plain old unstable. Wouldn't even get into windows without freezing up. I've tried numerous other settings but still no luck.
Overclocking with the RAM at 4-4-4-15 resulted in an issue where the PC simply refused to post so I had to clear the cmos several times (as I tried different settings). So I ask what are the best overclock settings I can get for 24/7 use? I do a bit of gaming and enjoy benchmarking. Currently I managed 10996pts in 3DM06
