Yup :) Oh and i had some slight issues with my volt mods. Mainly VTT went wack on me. I ended up replaces the 1k ohm vario with the same. But i decided to add a 1/8 watt to my varios for VDD and VTT. Both were 50 ohms and i added them to the ground side of pin in series. Anyways it seems to be working again and i just managed to raise my corsairs pc3500 max to 260 cas2-2-2-5 Turbo cpc enabled hehe
Interesting but i tried running 1 stick of hyperX pc3000 at a time to see what max they could do with streetracer enabled. 1 did 264 and the other 256. So swapped that slow sucker at the store for another stick and tried that one by itself and it ran at 264 also. Then tried em in dual channel with the following settings
255mhz / 260mhz
2 / 2
5 / 5
2 / 2
2 / 2
streetracer/turbo
enhanced /enhanced
5 / 5
enabled /enabled
enabled /enabled
I actually tried streetracer at 260 and it didn't work and that's why i listed it with turbo. I haven't even tried 256-259 in streetracer mode yet. my VDD set at 3.55 fluctuates to below 3.523 so i'll probably have to raise my 3.3v line a bit more. I think it's at 3.850 currently hehe
well, I have now given up on the Ic7 Max3.. I have come to the conclusion it is the most expensive piece of S$$$ I have ever Bought...
time to go back to an asus or abandon it completely. Having too much fun with my athlon64 right now..
ok, let me get this straight...
there are 3 mods done here..
the vdimm stabilaztion mod, that bigtoe says to remove MC64 resistor. now, what do you do after you've removed that resistor? nothing?
then, the vdd mod,
you cut the trace that goes up and to the right on the back of the board. then you measure the resistance of the bottom leg of the upper right mosfet on the mobo (making this the right leg if looking the right way at it), it should read 5 mega ohms. I can then solder a 1k VR set to 320 Ohms to the left side of the MC50 and the bottom leg(right leg) of the mosfet in the upper right corner. (what do i do about the MC50 resistor? do i remove it? )
now, from here for the VTT mod, can i use a 1kVR with a 1kfixed resistor in parallel to make it essentially 2k VR (adjustable from 2k-1k ?)? I solder a outside leg of this new VR to the leg that is attached to the left side of the MC50 resistor. I then solder the middle leg to a GND.
Where do I check the volts of each mod, and what are the "suggested" ranges? also, for each mod, which ones do i increase resistance to decrease voltage, and which do i decrease resistance to increase voltage? or do i just want to increase volts on both mods?
Stang_man it depends if you're referring to the ic7 or ic7max3. MC64 should be removed from both the ic7 and ic7max3 for VDD voltage fluctuation. Although it appears to really only affect the max3 at 2.9v+. To mod VDD on the ic7 remove R50 and use a 1k ohm vario with center leg soldered to bottom pad of where r50 was and left leg to upper pad of where r50 was and right leg to ground. Resistance between center leg and left leg set at 100 ohms to start. For a max3 leave R50 alone but after removing mc64 use a 2k ohm vario where mc64 was. Only 2 legs of the vario are required. Center leg and right or left leg. Now for VTT for a ic7 and ic7max3 remove mc50. Then cut trace on back of mobo. Check resistance between the upper mosfets lower leg and left side of where mc50 was. SHould read 500k ohms to 5 megaohms. Now use a 1k vario with center leg soldered to left side of where mc50 was and left leg to right side of where mc50 was then solder a wire from upper mosfets lower leg to right leg of vario. Now set resistance between right leg and center pin at 100 ohms to start. That about covers all the mods for memory. Do a username search catch22atplay for other threads that cover this mod as well. Dan that was a lot of typing. I hope i got that right :)
this is on Orian's IC7 Max 3...Quote:

which side of MC64 do i solder a 2k VR too?, and then this VR goes to ground right?
can i use a 1k fixed resistor in parallel with a 1k VR to make it adjustable between 1k and 2k? and what do i set the resistance too?
VTT seems really easy, it's just this little bit of confusion ^^
hope i get this right on his board... :p:
here's the VTT mod explained in a picture :)
Stang_Man,
can you do one of those pics for the IC7 VTT mod?
That's a pic you posted is a lot easier to understand IMO.
Thanks,
Minny
that also works for IC7 (according to catch)Quote:

So that 1K VR must be set to 100 ohms... then all we need to do next is remove mc64 and cut the trace behind the mobo?Quote:

Is this correct?
that 1k VR must be set to 100Ohms between the bottom leg of the mosfet (green wire), and the left side of MC50 (red wire).Quote:

this is a different mod... and I can't answer these questions, as I'm unsure myselfQuote:

Ok so we are about to do this to my ic7-max3 board. Now my questions are...
VDD mod affects the vdimm stabalization above 2.9vdimm correct This simply involves removing the MC64 cap and replacing it with a 2k ohm vario? What side of MC64 do we solder this to? I do not think radio shack has these...
VTT mod also affects vdimm stabalization? I'm just looking for a clear explanation of what these mods exactly do.
Thanks for the tip. I'll have a proper look at my mobo to find that MC50 & go fro there.Quote:

One more Q. Would it be alright to set the 1K Ohm VR to 1K & then lower the resistance as needed? I'm half thinking it's the same as the Vmem mod but want to be 110% sure B4 I go ahead with anything.
Oh yeah, I'm talking about stabilising my VTT on my IC7-G as I've done the Vmem mod & now it behaves like a good Max3. My dead Max3 could do over 2.9v with ease & stability but the VTT was around 1.3vtt-1.35vtt. Same thing is happening with my IC7-G so I'm looking to do the VTT for it.
/me rubbing hands waiting for delivery of BH-5 chipped XMS-3500 rev1.1.
Thanks:)

Look for madcats1968's post...awesome work
What can i use to get the MC64 removed?
I dont have this soldiering thing. Can i just use something to cut it in two? Will anything work?
Stang_Man,
I get it now. I was too worried with looking at your posted pics & didn't realise that you'd mentioned that it was for both the IC7/IC7-Max3.
I might just wait that bit longer til my BH-5's arrive & test them out with my already Vmem nodded IC7-G & if it does present a problem then I'll get the VTT mod done.
Thanks for everyone's help.
bump for Catch.
Bump?? er what i do now? Damnit i can't get my agp mod to work for some reason. Bought 2 P4 2.4 SL6Z3 cpu's the other day. I've only tried one so far and max i've had it with stock vcore and my IC7 undervolts a bit was 310FSB. Here's a pic below at 304.7FSB. Crappy score cuase i was only testing the cpu. Mem is extremely relaxed etc. Hoping the other 2.4 runs just as well.
bigtoe.... all you have to do is remove the cap?? thats it??Quote:

Im doing the mod myself in a coupple a days. I have the MAX3 board. So, to get one thing straight, can i just remove MC64 and the board will work fine afterwoods without that MC64? or do i have to do something else to get it to work?
I thought it was just to remove the MC64, nothing more.
Can somebody please confirm to me that to do the mod, you ONLY have to remove MC64 on a MAX3 ?
Im doing the mod in the weekend, so i whant to know first what im doing!
thanx :)
Please read through this thread properly. At the start of the thread "bigtoe" basically tells you what you need to do. Even on the page you're on there is your answer.Quote:

Yes I do think that is all you do for the Max 3 stabilisation.
edit:
Tried to PM Bigtoe about this?
see thats all bigtoe said to do but then catch22 comes in and says a whole bunch of stuff...
Well if all you want to do is fixed VDD volts from going crazy then just remove that mc64. If your vdd acts normal then there isn't any reason to remove it. I never had any vdd fluctuations. I just needed the vtt mod for when you set vdd to 2.9 or above. Had to fix it for tighter ddr timings and higher ddr o/c. Just mod what needs to be modded for what you want the mobo to do. Me i need it to run at 350fsb. That takes vdd/vtt/vnorth/vagp mods plus a damn fine custom psu.
