Before overclocking, you should establish that your machine is stable at stock. Run a memtest86 on your RAM - at least one full pass off the 10 tests. Then, stress the CPU/MEM with Orthos Stress Prime (blended test) - 1 to 2 hours minimum.

Thanks for the reply. I just finished testing stability. Passed all memtest tests.
temps at idle as read by core temp and speed fan. ambient temp 73F
core temp
core 1 - 44C
core 2 - 41C
speed fan
sys - 41C
cpu - 34C
temps under load using Orthos

This was after lowering the vcore voltage to 1.225 as you suggested to someone else earlier. I ran Orthos yesterday with the vcore set to auto which was at 1.30v and my load core temps were 69C and 68C, also yesterday I had Q fan enabled. Today I disabled
Q fan and used speed fan. Do you think the vcore voltage adjustment accounts for the 15 degree drop or did speed fan play a part? Am I right in assuming it is safe to run at 1.25 vcore?
I have one other issue, and that is a long boot time. I have already disabled Q fan but the boot time remains unchanged. It seems to take awhile after detecting the memory.
Any suggestions?
Thanks again.

Starting with the boot issue: do you have any USB storage devices connected? That's usually the culprit when suffering from long POST times.
re: temp change
The drop in your temps is definitely a result of both the lower vcore and disabling of Qfan. You have less voltage, and better airflow since your CPU fan will now spin at 100% rpm. Your temps are still a bit high. Nothing to worry about, but not as low as they could be. What is your ambient room temp? Do you have at least one intake fan at the front of the case, and one exhaust at the back? Good airflow through the case is key.
re: low vcore
Yes, it's perfectly safe to undervolt, as long as the machine passes stability tests.
