STEvil, Yes, we have the same layout and chip sets. I can't attach any files, as there's no browse option available to me.

Anyway, I measured the voltage on the 4 pins that are below these two chipsets (regulators??). I believe that the pin are from the capacitors on the front side. I numbered the first row from left to right: 1, 2, and 3. Then below #3 is the last pin, so it's #4.

From a common Grd to #1 =7.5v, #2 =1.255v, #3 =7.5v, #4 =2.854v....Between #1 and #2 =1.248v, #3 and #4 =2.846v.

I'm hoping that this is the memory voltage that we're trying to increase and the correct place to measure it. :)

Anyone want to host/post a digital image of the upper backside (behind the PSU connector) on a Sapphire 9500np Red PCB with the Infineon 3.3 memory?

I've reduced the PNG file and it's only 230k....It's pretty clear! :)

email it to stevil_REMOVETHISBIT_@attcanada.net

I'll crunch it up as a jpg and post it.. dont need to be using killer high quality png's 8-)

Thanks STEvil :)

This is the backside of the card, behind the frontside PSU socket, on a Sapphire 9500np R30 card with Infineon 3.3 memory. Both of the 14 leg regulators are Intersil and I believe they control the vmem.

From a common Grd to #1 =7.5v, #2 =1.255v, #3 =7.5v and #4 =2.854volts

If I measure between #1 and #2 =1.248v and between #3 and #4 =2.846v.

#1 and #3 are negative and #2 and #4 are positive. We need some one to guide us in adding the proper resistance to the correct legs of one or both these regs, so we can increase the vmem. :)

Edit:// STEvil you did a great job on the pic/file! :)

Im thinking it will be the same as the old mod, as the Rev3 cards had a second controller, too. It was just smaller is all.. what it controlls I dont know, though.. 8-)

Maybe MrIcee would post a pic of his vmem on his Rev30 9700pro as a comparsion to our 9500np cards, as the pic he posted in this thread earlier (right upper side thin plate view) for the vcore mod looks exactly like my card in every detail...that might answer a question or two! :)

don't forget, mine is a 9700pro and it has the two regs instead of one..

Have you taken any measurements from those points so we can compare? Have you done a vmod? :)

Hiya back....Catch22:)

I need more parts before I can do mine 8-/

The multiturn pots are too expensive.. $13 each here 8-(

I'm very confused now. Let me get this straight.

Does this, 9700 vmod, also work on a 9500np(9700 pcb)?
Do i have to beware that there are several revisions on the market?
If so, wich revision is compatible with the 9700 vmod and wich revsion isnt.

DisposableHero :) what exactly did you do to your card....did your card back look like the pic that STEvil posted ? Did you mod this area or the area near the plate like MrIcee's pic............ and is your sig before/after the mod? :)

my sig is old :D sorry about that... just vmodded today...

i just did the 10k vr to the 18 pin on that chip under the heatspreader and then to ground

yeah like mr. icee

Does the vmem mod still work the same way with the newer PCB revision of the 9700Pro as well?

Here is a pic of my new 9700Pro rev3.0.

Anyone? There are now 2 IC's on the newer revisions

start testing the voltages with ur multimeter that should give u a good indication
