msgclb do you really need v>1.5 at 3.6??unstable at anything lower thhan 1.5v at 3.6?

Ok, just at first when there was no pics, I thought you were just posting about 5 words in each post :p:

You were just to fast for me to get my act together. Also, the server where my images are turned out to be down.

Yes. I started with the 1.475v that was necessary to get 3520MHz - 440FSB x8 4:5 stable and gradually worked up to the 1.525v. Using 1.5v I had a crash at 3 hours so I'm not sure that 1.525v would be stable going past the 4 hours where I stopped.

At this point I drop the multiplier to 7 to see if I could get 500FSB. I'd be surprised if I could get any higher that the 3500 - 500FSB x7 1:1.

why is your cpu pll voltage so high?:shrug: does it help with stability?

I started out with these minimum default settings to test 333FSB x8 DDR2-667 1:1.

Quote:

CPU Voltage: 1.35
CPU Voltage Reference: AUTO
CPU Voltage Damper: Enabled
CPU PLL Voltage: 1.50
DRAM Voltage: 2.20
FSB Termination Voltage: 1.20
North Bridge Voltage: 1.25
North Bridge Voltage Reference: AUTO
South Bridge Voltage: 1.05

When I found my max stable memory setting I was using the following:

Quote:

CPU Voltage: 1.35
CPU Voltage Reference: AUTO
CPU Voltage Damper: Enabled
CPU PLL Voltage: 1.50
DRAM Voltage: 2.20
FSB Termination Voltage: 1.20
North Bridge Voltage: 1.40
North Bridge Voltage Reference: AUTO
South Bridge Voltage: 1.20

To get 472FSB x7 DDR2-1180 4:5 stable I raised both vcore to 1.4v and cpu pll to 1.6v.

I don't remember why I raised cpu pll to 1.70v for 440FSB x8 DDR2-1100 4:5 but I believe I tested this after 450FSB x8 DDR2-900 1:1 and I had a hard time getting that stable. I raised vcore a couple of times and then cpu pll until I had vcore of 1.525v and cpu pll of 1.7v.

It looks like most of my tests show the following correlation:

vcore - cpu pll
1.35v - 1.50v
1.40v - 1.60v
1.475v - 1.70v

After getting a stable setting I haven't tried lowering cpu pll to see what would happen.

very through documentation

do u think that u could drop ur ram down to 4-4-4-12 or better. that ram should alot better

yeah...not impressed with that at all. I gotta say, so far I have not been impressed with too much of anythiing I have seen with these G0 steppings other than lower temps.

I will be going back to see what lower timings will do.

Great results :up: , I have the same exact stepping, L719A747. I can hit 3.6Ghz with less than stock volts though :confused: What's your max OC and FSB?

What settings do you use to hit 3.6Ghz? Am I going to have to get a Abit IP35 Pro? (That's a rhetorical question!)

So far these are my max OC / FSB.
3600MHz - 450FSB x8 1:1
3500MHz - 500FSB x7 1:1

I'm going to see if I can achieve these and higher OC / FSB using lower voltages.
