Would it be okay to put a drop of liqud tape on top of the resistor right about it for insulation and then move the new 3.3k resistor partially on top of it so I will have a place to solder? I want to make sure this won't cause problems.
@ hipro5 : nice work (I only "fly-ed" thru all posts in this thread & I have to say: finally someone had the guts to do some mods ... :) Check also mine proposal about certain possible mods, you my find something you missed:
My posts @ Dothan overclocking thread, first one with some not quite accurate statements, but others IMHO Ok! Resolving certain problems! Mods!

Quite a lot of stuff to read carefully, I know ... :) ; there are also some later posts explanation to read too ... & here is another idea also! http://www.xtremesystems.org/forums/...920#post946920
*BTW that chip you are all searching, it is a voltage clamp chip, maybe could be found on some dead MoBo ...
@ caater : thanks for info with PM :) ; will follow also this thread even if I am mainly interested right now on Wireless Stuff ...
@ you other guys too : check my smallest Win9x ever, running entirely in Ram from bootable CD at the end of page http://users.volja.net/image/Files/ResQsys.htm ; usefull also for testing max. Fsb & max. Mem. clock prior to run your main OS (preventing its corruption); if crashing when PC too much OC-ed, no harm! :) Good for testing!

Pretty sure that's a CPU problem, I had a B1 that wouldn't go past 158Mhz FSB on a board that does 173MHz on another B1 (native supporting board - no adaptor).Quote:

but here's pics of how i did it, with double and triple stacked 25v caps (only ones we had in stock) ;)
the solder points by the resistor is fine, it snot really burned, just looks that way in the pic
If the resistor was smaller, then it would not be easy for someone to grab it and solder it.......TOO tiny......With the resistor you have now, you can solder first one side so as to be holded down, and then solder it.....Afterwords, mesure it so as to see 1.24KHOhms and to be sure everythings is OK before you power up your PC.......I used to solder resistors 1206 onto 0603 ones......;)Quote:

Why don't you try 5:4 divider or even 3:2 so as to see your CPU's overclocability first and then try to find your rams fsb?......:)Quote:

on another note, do you know the vcore measure point (on the mobo) for the p4gd1? Asusprobe and bios both say about .07v higher than what i have set in bios, and i trust my multimeter a lot more than those readings hehe.
Lol cirthix this is exact same think happened to me. When i was moding with just a 3.3k res mod i broke a pin off. I dont think it's the pin that causes problem. In my case after this single Vmod i got a bit higher booting speed but overal overclock didnt improve much. Other mods that i dont have stuff for are important too i see. The thing is after that mod the res is there to stay. I tried removing it and the resistor on adapter i vmoded with this 3.3k one lost tolerence:) so it wold read allot lower voltage then before, Max Vcore i had was 1.4 when setting 1.6. As result i could only boot 200x11 even 2400g wodnt do.Quote:

Need to flash my p4c to p4p to get rid of Raid, having problems with it loading windows when MB is below -20c. Also my p4p boots much better at cold temps.
Hipro im gona get 780 soon and finish that adapter Vmods. So how many people got positive results when completing all the mods?

All the mods aren't yet released, Hypro's results are including mods that he hasn't unveiled yet. I think he has released stability mods but not yet the ones which allow to increase max oc.

I'm sorry to say that, but those solder joints look horrible. OK, I'm exaggerating a bit, but they sure don't look good. Be sure to use some solder flux (colophony) next time. You'll see the difference. ;)
@Jojo1971:
you should definitely use better solder next time. also, you should rotate that cap, it won't fit with the heatsink retention frame. i actually have mine standing straight up and down, it doesnt cause a problem wtih either the 7700cu or 7000alcu :)
Well cirthix...
If you have planned some dry ice or ln2 action, a standing cap wont do you good on the insulation :) you if he lays that would be better.
Can't wait to see this one. I take it then that even the Dothans droop enough for a mod to help...skipped em in the first place thinking that their lightweight power draw didn't warrant it.Quote:

Heh, I recently run DICE on my unmodded yet dothan rig and I forgot to insulate 1 side of adapter. After DICE session that side was beautifully covered with frost :D But hardware was and still is working thanks to nail polish :toast:Quote:

Is the mod you speak of red spot - 50kvr - ground? This is the vcore mod for p4c I have been doing for awhile now, and I prefer to the pin8 vmod on the adp3180. It works very well and not as many issues with ovp latch off.... maybe coincidence, but at least thats what it seems so far.
Hipro, I managed to knock off the VCCA mod yesterday, then after that it was busted and my cpu's were doing crappy speeds of like 2.2ghz.. :S
today, I was trying to fix it and sort out the problem, but when I powered up, there was a POP and a puff of smoke :S , do you think it may have taken my golden 760 with it? :(
There appears to be no visible damage to the ct479, motherboard, or 760 so.. :S
any ideas?
Cheers.
PS: new one will arrive tomorrow..
Thats the one man, I serched for continiuty from pin 8 since i realy hate to solder to it with my not so pro toolset. Have 75K ohms resistor on this mod. I had a realy big drop on this board and the reg drop mod dint fix it. But this one just keeps my vcore so stable it wont drop at all even at load. I also did the Vagp and set it to 1.88 for now. So far i only manage 1060 FSb with this p4c board reg cooling but my p4p did 1200 easy.Could also be the cpu since i changed it.Quote:

but it's kinda overclocking crap, only doing like 2.7-2.75 :S
think it might just need some mods tho..
