Scratch that, got another idea.

Take two VRs and arrange them like this:



Set VR 2 to 500 ohms. Set VR 1 to 100 ohms. This sound produce 4.16v at that leg. If that circuit is designed the way I think it is, the mem volts should be 1.58v when you turn it on.

If so, then slowly reduce the resistance of VR1 and see if the mem volts change.

Whoa I'll try that when I'm back home. Until then...

Happy new year and have a great first guys! biggrin.gif
post #255 of 281
Any progress?
This might work

5v in and turn the pot to get what you want out, desolder the 1.58v leg on that regulator and wire it to the positive output leg and ground to ground
I should game.

Okay, so here's my current setup:



Just making sure: Is that the proper setup to fire up?
post #257 of 281
Is that leg unsolder from the pcb if so then it looks good.
I should game.

So assuming you do get 1.58v on the mem with that setup, then slowly decrease the 100 ohm VR and see how the volts change.

It's POSTing with 1.75V, so I regulated it down (increasing resistance on VR1) to 1.58V before booting into windows. Close enough thumb.gif
post #260 of 281
Hmmm no chance. During the welcome screen the voltage jumps around between 0.94V and 1.36V, then a black screen and reboot...

I'm guessing the 5V line is too unstable? I'm using the one where the HDDs are hooked onto.
