so how many volts have you pumped into your ram so far?

No more than 3.7Vmem...........I'll pelt them and I'll try higher........

Does this VTT mod sound ok, to you?

1. Cut trace from back of the board
2. Leave MC50 cap in its place, and solder wire from center leg of vr to its upper side (closer to Winbond chip).
3. Solder wire from vr to VTT mosfet lower (source) leg.
4. Solder last free leg of vr to ground.

Resistance (of vr) between MC50 and VTT mosfet should be first 0ohms, right?

Thanks

Yes it's OK......BUT you have to solder the wire of the Mos-Fet on the Drain of the one and Source of the other(closer to rams) where we measure the VTT......

Can you clear it little bit?

So one wire goes to MC50 side, one to mosfet (Q6) leg, where the VTT is measured, and the last one to?

Thanks again

If you don't solder a resistor(as you say) then it's going to ground......

Thanks for your efforts m8

VTT, VDDR and Vchip mods work like charm.

Tomorrow Im trying to get in serious business

[flapperhead]

hipro, ive done all 5 of your mods. 4 work like a charm xcept the vtt mod.(i did the second vtt mod cutting trace on back of board/with vr pot) i found that it just burns up any pot used(cause it needs almost a dead short to work). the only way i can get it to track1/2 vtt is to use a .25 ohm 3watt resistor to grd instead of the vr pot.. can u help??? thnx


update well, seems i burned up or severly weakened the power mosfets to the vtt . funny right after i posted this ,the rig just shut
down and on inspection the far right hand power vtt mosfet was burned. tho the rigg runs i can only get 1 volt thru to feed my vtt.Well daddy hipro, any suggestions??? or am i sunk.... thnx flapper

[enzoR]

use malves method for the VTT mod

[The Stilt]

Mods seemed to help my IC7-Max @ IC7-G Downgrade littlebit
Thou I have to make Vnorth mod, because it give only 1.22V by default, when using prescotts

[hipro5]

Well done The Stilt..........

Try to up the Vagp at 1.95Volts when playing with 1:1 CPU:RAM........

You might have soldered the trimmer to the Mos-Fet's side.......Check if you soldered them to the M64 side.......(of the 10 Ohms resistor).....

[enzoR]

hipro, to do the 5v mem mod which leg of the mosfets do i need to lift up and do i need to lift up both mosfet legs?

[hipro5]

No......You have to lift up the leg of this Mos-Fet of the photo......The one which I've soldered the "fat" cable on.......Unsolder it with MUCH care not to break the Mos-Fet's case and feed it with 5Volts........


EDIT......After that you have to put heatsinks on the two output Ram's Mos-Fets(The big ones).....

soldered exactly as u diagarmmed.. is it worth it to change the mosfet out??

Which Mos-Fet's out?...

the mosfet that burned, was the 2nd vtt mosfet in the corner next to the dimm slot

Yes if you have another one from another mobo you can do it.....

[flapperhead]

thankyou hipro i will try.. im pretty good at this cause i work in hi -tech(tho u are my master). i followed this mod EXACTLTY what do u think happened?? im at a loss.... without prints i find it difficult to trak what went wrong....
