PCIe freq. over 100 does nothing but increase the chances of data corruption and other problems. It does NOT increase performance. Unless you have a 9600gt

It seems to be stable at this. It won't remain stable at 3.5 for any long length of time.



Have I reached the top end? Are these voltages safe? Should I push it more tomorrow when I resume my trials or is this as far as I can get?
You can probably get some more out of it cause you voltage is still very low.

Alright I will put it back to 100.

What do you think of the rest? I can't seem to get it stable enough above 3.48 to keep it there 24/7.

Right now I am unable to make it crash during any of the testing programs at 3.48 so its stable as far as I am concerned.

With my current voltages, do you think I have any more room to go any higher safely?

You should be able to get to 440 FSB. That's around what I got on my chip.

well from what i can see you got plenty of head room on the cpu volatge as said before your max safe volatage on the 45nm chipset is 1.36 and still only at 1.2.
Id say kick it up and bit and 3.6 /3.8 is well there, on my own chip not the same i know. but 3.6 was a 1.25v and for 2.8 stable 1.35 is needed. anything up after that big jumps i will personaly say your going to be volatage bound nothing else.

I've got the voltage up to 1.34 and I am still having no luck above 438.

Get better cooling on your MOSFETs and NB, and increase the NB voltage.

If possible, get water.

My mobo did come with something for the NB, I will have to take a look at it.

Water isn't a possibility. I got it stable at 3.52, but when I put it to the max safe voltage and tried for 3.61, I am unable to get into windows.
Right now my settings are:

FSB Freq: 450
PCIE Freq: 100
vcore: 1.3625
MCH: 1.77
vdimm: 2.24
VTT: 1.64

Am I safe with those? Should I push it further? What is the maximum safe operating range on the rest of the voltages?

Is your board an x38/48? They are much more FSB limited than P35.

The MCH looks a bit high if thats the NB, although I am only going off the default voltage for P35, I have no idea about the x38/48. You can probably go to 1.4v on the CPU, but I would go no higher than that on air.
