Default Are my settings alright for long-term running?

I have an ASUS P5K with an E4500 (M0 stepping, VID: v1.3250) running at 3GHz. Just wondering if these settings are okay to run 24/7.
RAM is 2x1GB Mushkin 991603 running at DDR2-902, 4-4-4-12.

CPU Multi = 10x
Bus speed = 300 MHz
vCore = 1.45v
CPU PLL Voltage = 1.5v
FSB Termination Voltage = 1.3v
DRAM Voltage = 1.9v
NB Voltage = 1.4v

This is my most stable overclock so far. It ran with 5 runs of IntelBurnTest v2.51, and 8 hours of Orthos. Even setting the vCore down one step (1.4375v) caused it to blue screen when running the burn test.

My only question is will the vCore of 1.45v signifigantly affect the life of the processor? During idle the vCore is 1.424v and during load, 1.346v. (According to CPU-Z v1.56)

TIA!

just make sure your temps are under control though and you should be good to go.

Ah, forgot to include those. At idle, she sits around 39-41C. During load with IntelBurnTest, it can get as high as 65C, and 52C for Orthos.

Default Temps

Those temps look fine for 24/7. Looks good!

Thanks for the replies. If anyone has the same board and processor as me, how are you able to get above 3.0GHz? I've tried all sorts of settings, but none will boot into Windows at 1.45v, and I don't think it would be safe to have the voltage over that for long periods of time.

higher NB, PLL and termination voltages, push 1.47v on the cpu, the rather large droop should make up for it anyways. check your ram speed and timings as well in correlation to the FSB speed. have you dropped the divider?

I was told the termination voltage should not be put any higher than 1.3.

Raising the NB and PLL voltages from 1.4 and 1.5 don't seem to help. Plus, I only have two options for PLL voltage, 1.5 and 1.7. I think 1.7 is a little high.

I don't really understand how RAM speed/timings and dividers work, so I didn't do much with that. Right now, at DDR2-902, 4-4-4-12, 2.0v (had to raise this due to multiple blue screens), I have an FSB:DRAM ratio of 2:3.

well it's quite important, if you're running the ram too fast the computer isn't going to boot proper or will cause errors. you need to make sure if you're overclocking the CPU you gotta leave the ram at as to stock speed as possible.

Duly noted. This is what probably caused the BSOD's I had during startup and playing games.
