CPU PLL Voltage?

post #1 of 10
Thread Starter 
I have a stable overclock at 3.8ghz at 1.4v, but even at 1.45v I can't get to 4.0ghz without crashing in LinX. I'm wondering if increasing the CPU PLL voltage would make it any more stable. Thanks.

PLL is a chip on your motherboard, which calibrates the CPUs clocks and voltages. Increasing the PLL voltage isn't going to do you any good.
You need to keep your temps cool and try 1.5V. If it still isn't stable then you just can't go 4GHz.

the CPU PLL Voltage on my board is set to 2.5v by default... i read everywhere that a value around ~1.5v is recommended... should i lower this? it seems very high compared to everything i read so far:O

PLL only helps your system boot at a high clock speed, so no, it wont help at all. if youre lookign for stability then focus on the vcore, termination, AND northbridge. more than two cores will require a good amount of northbridge voltage as well as termination

actually i was just wondering why the voltage is so high, in every thread i read the PLL seems to be around 1.5v and not 2.5v... got me a bit worried:O
