System specs:

MSI 870a-G54 mainboard (latest firmware)
Phenom II x2 555 Black Edition rev c3 w/ coolermaster hyper 212+
2x2gb g-skill ripjaws 7-8-7-24 1333 1.599v f3-12800cl7d-4gbrm
1x sapphire radeon 5770
1x dvd/rw
1x WD 640gb Black
1x OCZ Vertex 2 60gb
3x 120mm lighted case fans
Antex neohe 500w psu


Have already read through the black edition overclock guide, and for my system at least it has been little help. From everything I read most people go up to 3.8 ghz on stock voltages. I have bumped the voltage to 1.424v (cpuz) and can only run stable at 3.6ghz. Have left cpu-nb voltages on auto for now, raising them doesn't seem to help stability, have also tried lowering memory clock to 1066 to no avail. Running the latest bios for my board. I had ocz memory in before and could only get the system stable at 3.4ghz.

Only using the multiplier to overclock, tried the built in overclock genie and it lowered my ram clock to 6** and only got the cpu up to ~3.5ghz.

Any help appreciated.

Have also tried unlocking cores at stock clock speeds, not stable at all.
 
Hi and welcome to Tom's forum.

Your RAM is rated at 1600, so, I don't know why you are running it at 1333MHz.

You need disable in BIOS the following options: C1E support and Cool'n'Quite, after that set your CPU at stock speed and run some stress test for 30 minutes.

Let me know the results and LOAD TEMPS.

For whatever reason I can't run my memory at 1600 at advertised timing specs, it defaults to 1333 at 8-8-8-24, runs 7-8-7-24 fine at 1333 but won't post at 1600. Will only post at 1600 with auto timing selected which puts it at 11-11-13-24. I think I'm better with the tighter timings and slower speed.

I have already disabled c1e and cool n quite.

I ran prime 95 for 20-30 minutes on my current configuration (3.6ghz) and it runs fine. Just need help getting up to the 3.8-4.0ghz mark.

At current setting load temps are 35-36* Idle is 26-28*
 
You won't get the CPU work with the same settings that the club, since even if the CPU are the same, components and conditions are different.

1.4V for 3.6GHZ is high more if you keep in mind that maybe people can do the 3.6GHz at stock voltage.

Try with 1.5V on CPU.

That's what has me confused, 3.6ghz at stock voltage for everyone else. I will try at 1.5v, what ghz should I try at that voltage, and is 1.5v safe for a computer running most of the day. business/gaming pc.

Ok if I put voltage up to 1.5v it won't post....I checked the HW monitor in my bios and my PSU isn't putting out exactly 12v, quite a few under, same with 5v and 3.3v....could this be a psu issue? Or are those voltages not typically directly on.

I just bought the same one to replace an older 535W Enermax and the Antec (Seasonic) is at least as nice as the Enermax and the semi-modular cables make the clutter issue so much better.

PSU installed...definitely part of the problem...only upto 3.7ghz now, not stable at 3.8ghz even with loose ram timings and slower ram speed and 1.5v to the cpu....do I need to adjust any other voltages to get her up to 3.8-4ghz? Not even sure what the other voltages do....and still no-go unlocking cores.

Voltages per bios are just about dead on with the new psu, which is nice.

Well, now this is annoying....not stable at 3.7ghz....right back to where I started at.....any more suggestions?

And apparently core temp was giving me inaccurate readings....

cpu full load temp is 42-44*
idle is around 33-34*
