I was hoping someone could help me out with my voltage on my p5kpl-cm board.
I have a q9450 quad core and am tyring to OC it to 3.2ghz but by simply increasing the FSB to 400
prime95 has errors in one of the cores so I assume I need more voltage.
In my bios the voltage settings are as follows:
1.8 Dual Over Voltage - Auto, 1.80V, 2.00V, 2.25V
VTT_CPU Over Voltage - Auto, 1.2V, 1.3V
1.25 Over Voltage - Auto, 1.25V, 1.4V
1.5 Over Voltage - Auto, 1.5V, 1.6V
"VTT_CPU Over Voltage" I'm pretty sure that's the vcore voltage.
No matter what setting I put it to, Auto, 1.2 or 1.3 the voltage stays the same in CPU-Z and I continue
to get errors in prime95 in one of the cores.
Does my board just suck so badly that I am only able to OC to about 3ghz?
I'd like to get to 3.2 to get a 1 to 1 ratio.
Find the hardware monitor in the bios. It should monitor the cpu voltage. Then increase some voltage and see whether the cpu voltage goes up.
Well I tried every possible combination on all 4 voltage settings with no change in my VCore voltage
I found a description of the voltage settings btw.
"1.8v Dual Over Voltage" is "Manual Set Memory Voltage"
"VTT_CPU Over Voltage" is "Manual Set FSB Termination Voltage"
"1.25v Over Voltage" is "Manual Set MCH Chipset Voltage"
"1.5v Over Voltage" is "Maunual Set ICH Chipset Voltage"
I cant find any other voltage settings in my bios so perhaps Im just out of luck with this motherboard.
Anytime i go past 3ghz I end up getting errors in 1 core on prime95.
That's the name I was looking for: FSB Termination Voltage.
I guess you're indeed out of luck with this motherboard. Maybe a newer bios version adds that setting but I doubt it. Anyway it's very strange to see such an important voltage setting is missing.
