Hm I think I'll better wait a bit and see how this thread here developes. :rolleyes:
Hm could someone please take a look at my last post.

I do hope there are some peeps arnd tonite
I have done the mod using 3.9kohm resistors. Ive have booted up fine. I decided to use my palomino just incase damage was done to the processor.
Now the information I would like to konw is, what would the effects of this mod be in the state and safety of the processor in the mthbrd.
For example should i be worried abt doing certain tasks like priming, benching etc. What would happen if this mod wasnt safe etc etc.
Seeing no noe has done this be4 with the resistor i am using could someone theretcially explain the dangers.
thanxs

Thanks for that Vlad, free lesson in electronics.. ;)
Any success to report, mong? :D
I have some bad news guys,
Any results that I was gonna share with you are now no longer. During the process of removing/replacing the motherbord over the last few days and having to remove my waterblocks and put them back on I had an accident.
The mods seemed to be working, I had not got round to fully testing stability because with the mobo on my workbench all i could use on my CPU was a crappy aluminium heatsink. There was no way I was gonna put 2volts through my barton on that thing.
So i had to install the mthbrs back into the case and reattach all the water blocks. Having done that I booted up and all seemed to be fine. I had some things to do and left my PC on. L8er when I came back I was greeted with a blank screen.
I tried to reboot it, but it wouldnt do anything, so I took a closer look at the components when i noticed that something bad had happened. Some how from all the moving abt I had sprung a leak, yup water had caused several pieces of hardware to short out. There were charcoled components, it looked like I had lost
the mthbrd, my gfx card, the relay, maybe the processor and ram.
:(
I took everythin apart and started to examine the parts closely, the AGP slot on the mthbrd had dry green powder inside the slot (those of you who have seen this be4 will now what i am on abt).
The PCI slot below the AGP slot was burned in one corner to the extent that I could put a whole through the plastic, the 9800 had one of the traces which goes into the AGP slot burned from the short.
Need I go on, everything looked bleak. I looked to see what i could save. First was to clean up the mthbrd and see if it was working at all. I cleaned as much of the charcoal and green dust as well as i could out of the AGP and PCI slot and around the motherboard. The scorched plastic PCI slot was tidyed up, this is when i noticed the hole which had formed in the plastic. I was happy with my 'cleaning' result and went ahead with a geforce mx and tried to boot. To my suprise it booted! Yipee (my hapiness was to be shotlived more of this l8r).
One down two to go, so far the mthbrd was working, my barton was working and the RAM was working. Now for the 9800, i cleaned up all the green dust which had accumatlated from where it had been pluged into the APG slot and cleaned up the charcoled traces. Fortunately only one of the traces was burned out. I decided to bridge the trace with a small piece of wire and solder.
I threw the gfx card into the mthbrd and tried to boot, success the 9800 was working I coudnt believe my luck, 2pieces of scorhed hardware which i had manged to ressurect from the dead. Last thing left was the relay. This had a corner burned, the corner which was in the PCi slot which had turned to charcoal. the slot which goes into the PCI needed cleaning and the corner needed to be remade. I used superglue to slowly mould a new corner, and repositioned the trace which once used to be there back onto its spot. Being a perfectionist I developed a new pin for the PCI slot (2 of the pins had burned to dust!!!) and believe it or not i manged to get it functional. So everything was working. Wow it was hardwork, but worth it, until the inevitable happened.
Everything was going very nicely, I was talking with my housemate and had just started to tidy up my case. I rebooted the computer but had forgot to plug in my sata drive so I turned it back off. That was the last time my Infinty ever booted
:( :(
For whatever reason It just died, now what I dont know is the following, did it die because of the short circuiting which had happened previously or did it die because of the voltage modifications. We will never know. L8r today I will contact the shop i bought the Infinity from and explain to them abt the
leakge. They are good people there so I am hoping they will be symaphetic and let me RMA my motherboard. If not I will have to bite the bullet and just buy a new one.
Hopefully by then U guys will have fully established the right values for the resistors in the mod. I dont regret for a second what has happened, you have to learn some way, I learned the hard way. I will now know that moving my waterblocks can turn a leak free water cooling solution into a bad accident, oh well.
I will post some pics l8r on of the hardware and my attempts to rectify the damaged pieces. Its now 4:30am here in the UK, I am mentally and physically exausted, but i cannot sleep yet. I need to get a computer ready for my housemate who needs a rendering machine for his degree project which he hands in on wednesday. This is what im typing on at the moment. Need to finish instalation of the software then i can go to bed.
Goodluck to the rest of you doing these mods, I hope you have a better day than the one i just had.
Thanxs for your efforts guys, especially to you Vlad your da man
:toast:
mongoled out
Let us pause for a moment of xtreme silent meditation for our dear departed.
Better luck on the next one mongoled :toast: Another member of the DFI Destruction Dudes ;)
Our condolences mongoled. Always sad when good hardware goes up in magic blue smoke. I think its a just a wee bit past being able to RMA, btw. :(
o
Thanxs for the messages guys,
sjohnson,
Maybe we should sort a special avatar/sig out for us guys to distinguish us from the normal modders
;)
Any ideas peeps please chime in.
DarKcyde,
Your prob right abt the RMA, I have PM the store owner and explained the circumstances, like i said be4 the are pretty cool their, the best customer service I have EVER seen!
Vlad Draculea,
I cleaned up the motherboard first using a solution compiled of cellulose thinners, it evaporates almost instantly and cleaned everything up nicely. A bit more detail on the mthbrd which may give a clue of cause of death. When trying to pwr up the mobo using both the 4 pin connector and the regular connector, on pressing the power switch there is activity for a fraction of a second (prob a thousandth! of a sec). If i unplug the 4 pin connector then the mobo powers up but doesnt boot (mthbrd fans sockets dont work)
I tried a diff power supply just to check that mine wasnt damaged but the PSU is fine.
So if i understand correctly from your calculations using 3.9kohm resistors will give a current of 90 amps?
mong
Oh. My condolences with you on your dead board :(
Apparently there seems to be an increased number of DFI deaths around :mad: in whatever circumstances... once it works (happiness), next time you're sure it works it's disappointing you :(
I today got a message from a friend (bought my LP and two infinities from him - he is forming a shoplike firm ;) ) he gets my last dead infinity replaced too... I was hoping for the money though... so I am gonna have two new infinities and one new LP B soon ;) But for rmaing infinities it takes DFI quite a long time :rolleyes: My friend says, LP is the prestige object of DFI, the infinity only the budget variant... so guess what. Right. The LP is being rmaed very fast, the infinity I am waiting for is still has not been rmaed for over three weeks now :rolleyes:
Hope you get an immediate replacement, mong :thumbsup:
q
mongoled have you try remove the batery and put the reset jumper in posicion reset about 30minutes?
Just a thought here....
I'm getting a new DFI from RMA...hopefuly. Anyways, to take care of the fluctuations, I've been thinking in doing the same as hipro did to the IC7. Soldering an additional choke and capacitors on the bottom of the board. Maybe this could be a safer approach.
Might sound a little dumb, but...
What 's a choke :confused: ?
A choke is one of those (typically) donut-shaped things with the copper wire wound around it.
Provides reactance to a circuit. Often used to filter "noise" out of a circuit via reactance and I'm sure something else (but d'oh, I don't know what).
u
Oh well, Ima try the caps and see how it goes. But it may take till next week for me to do it and have a feedback for you guys.
Thanks sjohnson for explanation :)Quote:

@others:
Already tried the caps-adding with several nf7-s' 2.0 and it never gained me anything :( (used original caps from nf7)
Seems it had sth to do with overcurrent as well, drawn ampage or not-drawn ampage ;)
I hope I don't end up modding my new board all-over... :rolleyes:
Please, guys, find out what mod is the most beneficial for vdimm/vcore/vdd stability at high clocks ;) :D
That's what I wanna do tomorrow or when lp b arrives. RMA was done on one day - replaced the board... gls should ship it today to me :thumbsup:
guess i am jumping out of the circuit here. Newegg is outta Infinity, so I got a refund. Think I'll just get a 2.4C and keep on going with my IC7 projects. :)
