I used a 1M pot but only because I ran out of 100k pots (which I reckon is the ideal value of VR) at that time, had to make do cos I couldn't be bothered walking to the nearest hardware store around 2 miles from here... :D

i used a 10k pot + a 14k fixed resistor and it looks like im at 2.84v woot!.
Crack up the memory pass the 900MHz mark...
well this got interesting. I was getting artifacts at desktop when clocking even after reducing voltage to 2.78 so i decide to rip off vmods till i do more homework. well i ripped to hard and ripped the 3rd resistor off and cant find it... :( so now my card is dead at the moment until i find the value of that resistor anyway.
Help please....
Ouch :bsod:, if you can find a resistor match you should be able to take the card into a good electrical repair shop, someone with the right tools and expert soldering skills should be able to fix it for you, if you are lucky they'll solder that resistor back on for just 10 bucks...
got lead wire already soldierd in place i have mucho cards to scavenge from tho i will prolly just use a fixed and or variable i just need to know the value of that particular resistor if possible so i have a range to work in.
Not sure how to tell the value of those tiny resistors, all I know is they are a :banana::banana::banana::banana::banana: to solder back on, just wait for one of those EE guys to turn up, they'd know... :)
just put one of your ohm meter leads on each soldiered end of it when card is off and thats it :) i already have the hard soldiering done now i just fill in the blank with appropriate value @ the ends of the wires ive attached. whew i may have dodged one here... circuit is functional
Yes but I go nuts with the hotglue gun (for good measure, see pics) after soldering the wire onto the resistors, it's all securely fixed under hotglue... :D
you read my mind, i already did that LOL :D
well im up and running but seeing some glitches! be nice to know the exact value of that resistor! :)
edit: card is running fine @ underclocked ram speeds :( cant complain at least i didnt fry it. my ram just didnt like volts at all.
Alright.. Upon reading all of the previous.. None of it sunk in. x_x
Could someone tell me in a neat little package on how to do the memory vmod on a 6800NU made by BFG? Right now I got the core at 1.5 with the bios mod and usin a NV5 for cooling, which works damned good so far.
I could probably understand it better if I read through it about 6 more times.. But im too scatterbrained right now. x-x
be very cautious with vddr mod as it didnt take much at all to make my rams act goofy. stock was 2.73 highest i went was 2.84.
So ive heard, although did it perm goofify the ram or did it clear up when you dropped the voltage down? I can get the ram up to 870 actually without artifacting, but some games just have to be bastards and throw artifacts around. Would adding voltage clear this up?
Oh, And also if the card yer talkin about is a NU card (A pic would be helpful) and ya point out where the resistor is, ill gladly give ya a readout.
more voltage definatly wouldn't hurt. I hear gddr3 dosn't like voltage too much, but I havn't tried myself nor heard of any actualy results.
Well if im not mistaken, NU cards dont have gddr3, but gddr1 or something. Would my kinda ram be sutible for this kinda mod anyway?
pump the voltage through it :) non ultras love voltage I hear, well not really, they are just given less than they need stock.
Yeah, Much less. They run at 1.2 stock. Right now I do have the core cranked to 1.5 and its overclocked to 420mhz, but the memory I can only really max out at 800-820 without any sort of artifacting. I can get it to 870, but then alot of the games start to artifact then, namely Halo with the snow and Rollercoaster Tycoon 3 showing messed up geometry, although no benches artifact.
Maybe I missed it, but are there schemetics for doin a memory vmod on an NU. (Jeeze, im so out of my mind today. Too much stress.. x-x ))
Performing the mod/s after ~20 cups of coffee is NOT recommended. :explode:
I take it you fried it?Quote:

This entire thread is about the voltage mods, you simply cannot miss it, unless your head is completely wasted... :DQuote:

Im a night owl, but unfortunately ive been having to get up early to work with mah grandpappy. Ill take another look through the topic when my mind is fully rested which should be tomorrow. If im not mistaken, I may have a few pots layin around. If not, Ill just take em offa my old Vmodded 5600.
No, Its not dead, just obsolete. :D
-Addendum-
Alright, Im havin a very hard time following whats needed for the volt mod. I saw stuff about adding caps to the board and I just feel like im leaving something out here. Not that its not outside of my ability, I just wanna make sure as to what all I will need to do this mod, although I dont plan on adding the extra molex. Tomorrow im gonna make one of my treks into town for once (Its about a 20 mile drive, I live out in the boonies of Texas) and I wanna go ahead and stop by RadioShack to get all I need. I dont wanna have to waste gas on multiple trips.
i've edited a bit the first post, enjoy ;)
Thank you! Good thing im at my wits today. :D
I got the caps from an assortment pack that Radio Shack had, Although the 3300's I have are rated for 25v.. It this still usable for the ddr cap mod? Also can I get a part number on the 100k risistor. All I have are the 10k-15 turn ones, or is there a topic around here that sports all the part numbers one needs for volt mods and such? That would be quite handy.. I may scrounge one up later if I have the time.
