all of them ON

my switch explanation
The Mem v, GUP v and PLL v all add a little votls. +0.050 if I remember right
OCP switches moves the ocp limit from (I think) 300a to about 500a
PWM - you can adjust the frequency from 260Mhz to 310Mhz
cold bug helps with cold boot issues, off CBB was about -80 for me on is about -140
I have always had both on ( the switch is upside down compared to the others)

To play safe - ALL of them (as in both switches on each block?)

Very nice tips there Splave

Allen, preparing to insulate my lightning, just wanted to check, does it need memory/vreg sinks????? Coz I dont see any on yours, also, would some1 be kind enuf to link me to the cold slow bios for lightning.......

Apart from the OCP mod, does it require any other mod???

Bro,

Splave told me he cut the base of the HSF and used that to cover the VRs, that's why you don't see any heat sinks. Memory is kept cold enough by the eraser (cover the mem chips) and the LN2 pot.

Also, you don't need the go slow bios flash because you set the card for LN2 and voltage with the switches on the back. Set ALL switches to on, then follow Splave's guide.

I'm going to run mine later today, if you want to look at the heatsinks I used check the thread I posted called "WWJD".

Splavious, if you read this, please check my pics and let me know if the other chips need sinks. I put sinks on all chips your plate covers (I believe)
