PLL voltage

[gurusan]

yeah they are low, but I think 1.65 is not needed. My P5E needed 1.55V for 520fsb and 4x1gb RAM

i have tried less than 1.65v but with no luck temps are below 50 degrees under full load, would it make a difference if you were running 2x2gb as opposed to 4x1gb?

 

[gurusan]

usually 2x2gb requires less NB voltage.

1.65 just seems like a lot to run 24/7 to me, but these are 90nm so if temps are under control I spose its ok

Why i sugegsted he steadily raise his nb voltage, he probably wont need as much as i do

if he's running 2 dimms then 1.31 is enough for P45. I have mine at 1.3V, along with 1.6V PLL and 1.2V VTT, it probably will do with a lot less PLL but have not got around to test it yet.

Well he's running a Rampage formula which is X48.

The p45 requires barely any voltage, I only need 1.26vNB for 500FSB and 4x1gb dimms at 1200mhz

in fact steve I'd try 1.22-1.24V nb, 1.52-1.54v PLL and 1.2-1.24VTT on your setup depending on what sort of FSB you want to run

 

[steve258]

Ah ic. Thanks will give that a try later

i've got 2x2Gb sticks of ram, running at 5-5-5-18 2t, which is at 1066MHz atm.

cpu-z vcore is at 1.336, whereas i set it at 1.3625 in bios.

i've got one of those piddly little rans on the NB atm (one of those fans you get to sit on the voltage regs) which is keeping it at around 45*C.

i'll give the nb a few extra volts and see if i can get it a bit more stable.

many thanks for the help guys

 

[twist3d0n3]

well, tried it with the nb at 1.45v, and got 2 seconds in orthos without an error, and then tried again with 1.51v, and got 3 seconds

don't think this wolfy wants to go any higher!
