Okay, here's my inexperience coming inot play here.

With VTT mod, I heard that macci left the MC50 in place & did the mod the same cept that the MC50 was still there.

first dilemma:
About cutting the trace at the back of the mobo, do I need to cut along the lines or is it as long as I snip the trace it's okay?

I seen some pics where the trace was basically cut nearly the full length of the trace. I'm thinking about just cutting straight across the trace instead of cutting along the trace?

I borrowed hipro5's pic & edited it to show the place/s where I'd be cutting the trace in blue, (I hope he doesn't mind, if hipro does not like it, I can erase the pic). I'm thinking that it'd do thae same job.

Double post but important to me none-the-less:

second dilemma:
With the Vdimm mod for the max3, can I do it by just taking soldering a 2K VR from the bottom pad of the MC64 & the bottom leg of the Winbond chip above the R50/MC64? Just like how I did it to the IC7-G?

What about soldering a 10Ohm fixed resistor plus 1K VR set to something between 100-220Ohms like the drawing of johnrr66 that I've modified to to show what my theory is about the Max3 Vmem mod?

Will this work?

I hope to get an answer within the next 24hors as Im taking the mobo, 9800XT & my new Enermax 460w PSU to my m8 to get modded somethime 2morrow.

TIA.
Cheers,

Out of curiousity, I measured the Vdd (Vchip) on my IC7-G with a Prescott installed, and it measured 1.28V.... I noted you said it was 1.49 in your notes. Is it possible that with a Prescott, it uses a lower VDD (Vchip)????

I am in the middle of doing the mod the Catch22 way but a worried as there isn't much feedback on whether Catch22's way works good or not.

I have taken the MC50 capacitor off & am worried that if Catch22's way doesn't work then I'm kinda stuck with another dead IC7-G board.

What I wanted to ask is if some kind soul could somehow measure or find out what the capacitance of that MC50 cap is. I would've done it with my dead IC7-G but silly me used that board as a practice board to take the MC50 off b y using the old fashioned way, with a plier....

I have this thought that most mobos use 10nf capacitors but would like someone with more experience than me (that's probably 90% of the XS members) to clarify this.

TIA,
Minnyboy:(

You can cut only at one "blue" point on the photo......

I had the same problem BUT with my GeForce 440MX overvolted........When I didn't overvolted my VGA,everything was OK.......I do not know about Proscott yet......

Hipro 5v mem mod plzz!!! v :D

YYYYEEEESSSS!!!!!

Done the Vmem mod with my "modified" hipro5 way on my IC7-G, also did the VTT mod the Catch22 way as described in my last few posts....

They're working perfectly!!!!

Next on my list, My Max3 mod, doing it the way in hipro5's guide. Not going too extreme, just the Vmem, VTT & that cap on the N/B.

Look out!!!! I learnt how to solder 2day as well!!!hahahahahaha!!!

No mobo, vid card, PSU is safe from me NOW!!:D :D :D :D :D

Thanks to hipro5, Catch22 & the many others that have helped an inexperienced modder!!!

Cheers,

A Toast To All:toast: :toast: :toast:

edit:
Mod works so good that I've able to get 2 x 512MB XMS3500 running at DDR496 (trying DDR500 right now). So far, DDR496 @ 3.3v/1.7VTT 2-5-2-2. not bad for 512Mb sticks in dual channel.

Hipro, nice work!!!! Helping the Abit's shine!!!

Question..... VAGP feeds VDD for the chipset? From reading around here and your webpage that's the conclusion I came up with. I have done Vdimm, and vtt mods to my max3, not sure about doing the vagp just yet but if vagp is left unmodded the max vdd for the chipset will be the 1.65 selectable through bios right? If so I can raise the vdd to 1.65 before needing the vagp mod?

Trying to get over a hurdle and hopefully this mod will do it.

Thanks!!!:toast:

yup. but the vagp also helps the chipset even if the chipset voltage isnt raised beasue thats the voltage that coes to it thought the agp bus

WOOHOO!!!

Now at DDR500 @ 3.4vdimm/1.7vtt @ 2-5-2-2 with my 2 x 256MB XMS3500 thanks to the Vmem mod (hipro5) & VTT Mod (Catch22 way).

Done 100 Memtest86+ runs of test 5 & 6, 50 runs of test 3, plus over 7 hours of all tests without a fault rearing it's ugly head!!

Got me new 3.0Ghz NW testing now at 280fsb (4.2Ghz:banana: :banana: ), hoping that she'll do fine.

Hipro please post the mod for puting 5v on the mosfets directly. thanks

Thank you....... :toast:

No. VDD is a different Voltage from Vagp.....You should do the Vagp mod... ;)

Thanks hipro:toast:

I've been able to set GAT @ turbo, enhanced, 5 Clocks, enabled, enabled & pass a few hours of Memtest86+ with these 2 "babies o' mine".

Got some 512MB sticks that'll do 240fsb 1/1 forever but as soon as I enabled CPC, it just dies.... I'm thinking it has something to do with being 512MB sticks... GAT @ auto, aggressive, 5 Clocks enabled, disabled.
Bandwidth reported by Memtest86+ is something like 3207MB/S...
Have yet to try Sandra unbuffered on them.

hipro, does your Ram give up on your when running 5/4 dividers?? I mean, do they get as high as they do 1/1 or do they give up earlier on 5/4??

My 2x512MB stick XMS3500 dies when dividers are used. Even 220 with GAT @ a, a, a, d, d they just throw up errors & then freeze my rig...

Haven't fully tested all my BH5 sticks - 6 x 256MB, 2 x 512MB - so hopefully I'll end up with some that'll do more than 250 1/1.
Sure beats the h3ll out of running my new 3.0Ghz with A-Data DDR500 @ 544 (2.5-5-4-4)...

Cheers mate,

Keep on breaking those records :thumbsup:
I think it'll be a while b4 someone else beats those records you set. Next clocest person is......HIPRO5

Keep on burn-in them M8.....

512MB Rams clocks a bit worse than 256MB ones....

Next project on going : Peltier 80 Watts and water on Northy to see how it does...... ;) :)

burned traces

OK. The temp on my regulated solder pencil accidently got bumped up (read without my knowledge) on my max 3. The traces burned on R50 on the max3 board, R46 seems damaged. Only the top layer is damaged. Can I salvage this board? Is there a way to make some direct connections, thereby bypassing the traces, or can I pick up the traces at another location?

What about plain old vcore mod?
We've tried to mod my vanilla IC7 but with no luck.
at ~1.9V board will hang.
tried to mod both vsen and vdiff legs - voltage was lowered
at these legs but still a no go.
an abit logic somewhere? :confused:
