Yea just a Maze4. It does the job pretty well, never gets over 35C even at 1.6+v VGPU during load.

Yea just a Maze4. It does the job pretty well, never gets over 35C even at 1.6+v VGPU during load.
do u know exactly where it would need to be soldered? and exactly what kind of resistor i would need? that v-mod might be easy enough for me to try it. yah i know... i shouldnt mess with v-modding if im not familiar with it, but hey, u gotta start somewhere, right? and where could i find a better place to learn then here?? :DQuote:

That's the guide I used, works like a charm :)
Now, for the heatsinks, does anyone know of any other S939 heatsinks that are more low profile that would fit on my 7800GT? I am using both of the PCI slots on my Ultra-D and the CNPS7000 won't fit :(
i did the pencil mod and only bumped it up from 2.03 stock to 2.09... I even went back and tried to darken it some, no difference...
Try another pen, woks fine for me. I got ~580 Ohm => 2.2v :D
Just measured my card and i got this;
2.17V Ram
1.61V GPU
And i have only done the biosmod, seems pretty high right?
Damn i want to do a real vmod, and up to 1.7V but i dont have the guts to do it :)
which rev is your XFX?
UDF7, is that is what you mean with rev?
But my card still only does 500 mhz with 1.61V, thats a bit wierd :/
I was asked to repair Leadtek 7800GT, it was v-modded, but it's owner crashed 2 resistors and damaged PCB. =( :eek:
So, I want to fix it, but I need to know a few things:
1. Nominal resistance of damaged resistors (1st is removed, 2nd marked as "damaged").
2. Look at the yellow and blue lines. Are they connected to the marked points?
Maybe somebody will measure this points and reply here?
I know, it'll be hard to solder resistors back, but hope I can do it. =)

I think, that correct is yellow line only, lost resistors give GND to one of voltage controller pins. (4th from bottom to top on the photo)
well i think i killed my card. I was doing the vgpu, and i think i shorted the wire to the resistor above the one to be modded. Now my voltage drops all the way down to .6v ....
EDIT : i mean .325v ...
i suspect it's not grounded properly, in that case. Where did you attach the ground point to?
oh its grounded, its snug inside a molex ground. Voltage starts @ 1.12, then slowly makes its way down to .325v
EDIT : Wow, and even better, it was just a hotglue mod, but when i was taking m ram sinks off (used half ceramique epoxy and arctice ceramique) popped of a bga. Nice. So now NO chance of an RMA... Man... looks like time for a 1900...
oh. I dunno then, over to the pros...
Holy :banana::banana::banana::banana: sounds like a bad day!Quote:

To get the rest of the sinks off
A) try the freezer trick ;)
B) heat it up with a hairdryer
To get that BGA back on you could
A) oven trick

@-De$troyeR-, nice quality job on your vmods.
Question....with an aftermarket cooler (h2o), does the onboard temp diode still work? Mine is 31c and never goes any higher even during 3D/05. I can't tell if it is reading or not.
mine usually read 31c idle, and around 37-38* max under load.
7800 sensors can't read below 31c. So you can assume that it is both idling well below, and loading at below 31c
mine usually read 31c idle, and around 37-38* max under load.

results after volt mod. i have very happy with these result sand i think it still has more.

Good work Cronic.
Some tweaks and LOD+3 and you'll be done.
Thanks, that's good news. NV-78 cooler with cold water. Had to insulate the entire copper portion and cut out places for memory and gpu.
**edit** Good work I guess cronic. That is fantastic score.

excuse my ignorance, but is diagnostic startup the same as safe mode? if not how do i get into it? thanksQuote:

I have a 7800gt coming my way, and I just read this entire thread... hmmm...
If you know what your doing, it is worth doing the mod, with little risk (given you know what you are doing and feel confident)
I have a question @ bAdboLL, if you read this, wana explain how you did that mod, how you mounted that CNPS7000 and how you have the card mounted (ie: anything stabilizing it, or holding it up)?
@ AFI: what cooling ya got goin on there? 1.8V makes me think subzero? :D
Update for anyone who might give a rats arse, my ripped off and then re-glued BGA RMA.... it worked. Oh yeah. Tracking number says it should arrive today. Its nice. But.. its a 518-BX ??? was AX before... whats that mean?
LOL nice
Got my 7800gt in. I now have a 7800gt and a highly overclockable x800gto² (does 620/620 stock volts on water). I'm not sure about which I should keep. I think the 7800gt can't break 500mhz gpu on stock volts. It's the 517 model.
I can volt mod both cards, but I hate switching my machines from ATI to nVidia and vice versa... even though drivercleaner helps a lot, the scores always end up being less than a clean format, and doing a clean format all the time gets annoying.
Decisions, decisions...
Was your 7800gt evga? The latest batch has really sucked for overclocking, I don't think I can get past 500mhz with 1.5v =0
Well you never know till you try, a lot of people said to stay away from PNY but this card turned out to be a beast and my Ti 200 is still chugging along to this day.:fact:Quote:

Where is the best point to solder + on??

Badboll, do you think the card could handle the all copper version?
Replied... keep your fingers crossed, Mikal. The problem may go away... I've had tons of funky stuff happen with BOTH of my DFI boards. One of them doesn't turn on with a power switch (neither case nor mobo power switch). I have to "jump it" every single time to turn it on, no matter what PSU. :(
Yehh...maybe I will start with that. :rolleyes:Quote:

Do anyone now?
I think 2.3v is fine for 24/7 as long as you have decent cooling, I know that the memory might actually get hoter from the NVS5
I did some research on the memory IC's a while back, they are designed to run something insane like 2.5 or 2.6v
So the memory get hoter from the NVS5 than stock...that no good!!
Are you sure??
I purshase a NV5 just for my memorys!! They clock 1080MHz with stockcooling! ;)
I've heard in many cases stock cooling actually does worse then running them bare. As for the NVS5, I don't have any proof of this, but if you take the concept that the same peice of copper which is being heated to 50-70C from the core, while the memory is running at a much lower temp, there is bound to be some unwanted heat transfer :P
As for my video card being flakey, I just tested it again, it must be the motherboard. I'll go on further in my other thread to not jack this one
Maby, but i think it will be a little too heavy for the poor card to handle :DQuote:

I have this one from using my NV Silencer, keeps the card nice and sturdy.
Wow... never heard of those, but that's pretty hot. My mobo to expansion slot is not 90 degrees, so it requires bending to fit my pci-e cards in nicely.
My 7800GT must be the worst card ever...I cant even do 1100MHz on my memorys!?
I dont get any artifact but it freezing and get a pattern over the windows.
My core handle 490MHz. I havent done any mod yet but I will never reach 500@1200 ...thats my goal!
I hope more voltage will help but I dont now.....
I share your same problem, with stock volts I can't even break ~490/1170. but with 2.3v my memory flies (or used to, I think it is artifacting at 1260 instead of 1370 like it used to)
The 7900 series is going to be very promising for high clocks, but why bother when G80 is SO close
Edit: At 1360 I get such SLIGHT artifacting, sometimes a couple red/white or discolored pixels appear on the screen. I am wondering if I should up from 2.31v or get better memory cooling
I tryed this pencilmod but it did not work so well. I decreased the resistance to ~575ohm (~2.25V) but after 20 sec in windows my screen freeze with a pattern over the sreen!? No Iám running with org. voltage again.
Can the freq to PCIex slot have effect? My setting is 100 (org).
What more can I do/test??
i can run 525/1220 and that's only with the bios 1.5v trick. i'll be doing a hard mod next month when i go back to work and my soldering desk:D i'm gonna have to get rid of my stock copper hsf though for some nice reliable voltages and temps. it's not the card but rather the luck of the draw when it comes to overclocking.
1.5v is the most volt u can give with only softmod, right?
just picked up a used evga 7800gt (445/1070 version -518?) and did did the vcore hardmod and penciled for 2.26v vmem. w/ 1.66v on the core it is stable at 570/1380 - watercooled - core under load hits 38c. seems like pretty typical clocks.
Hmmm....why cant I oc my memory "at all".....not even with more voltage!?
Can I do the biosmod (nibitor) with a cd?...I dont have a floppy.
I never use a floppy when flashing a bios... I have a very small FAT32 partition on my harddisk, because FAT32 is accessible in DOS, and I boot up from my old Win98 cd and then select boot from cdrom.Quote:

Holy crap Garret that's one hell of an idea! Why didn't I ever think of that? Haha. Hi everyone, I'm new to XS as you can tell, I have yet to set my avatar and such. I was just wondering what everyone was getting for max core clocks. I ask only core clocks because it seems everyone is limited on they're memory at around 1380~1400MHz. I for one have been running 621MHz at 1.83v 24/7 without a hitch. I think we all know that there's no point in trying to squeeze a few more MHz out when you won't see a performance jump until you get 27MHz. I seem to have hit a voltage wall and I don't think running at 648MHz is attainable. Has anyone found what the max voltage is on these cores before they simply won't boot? Am I going to fry my beautiful performing card if I try to find out? Haha, if there's some form of over voltage protection I'll shoot for 650MHz even though I don't think it's happening. Currently I can't seem to break 61°C during RTHDR (that insanely awesome HD real time rendering 3D app.) or whatever It's called. That seems to push my card the hardest, during BF2 I tend to see temperatures in the fiftys. I plan on going H2O when I go SLi, but first I need those G71's to cause some price drops. Also has anyone else seen memory stability degradation over time? I'm not sure if I ran them a little high to start, but Infineon says these are good for 2.5v and I was running 2.4v 1400MHz hella stable, but recently I've had recently I've had issues running 1400MHz and only do it for benching purposes, heck I can't even run 2.4v at 1390 anymore without that weird screen grid lock up deal, I now run 1390MHz at 2.3v 24/7. So I guess the purpose of this post was to find out two things, what has everyone been maxing out on the core (don't bother telling if you haven't hard volt modded yet), and has anyone else seen this memory degradation. If you have please tell what voltages you were running at to start and such. Thanks!
Mikal, I'm sorry to see that you lost that much on your memory, have you tried starting from ground zero and seeing what you can get at lower volts? Like in the 2.1~2's? That's what I did and found that I was artifact free at around 2.18, but after a few minutes to hours, almost randomly, It'd just lock up and I kept getting that until 2.3v. This Infineon seems to be some really weird stuff. Sorry for the lengthy post, good luck all!

My memory maxes out before 1200MHz on stock volts, I haven't tried lower yet. I am getting my water cooling setup this week/early next week and I plan to have this baby MAXED out or kill it trying, gota squeeze all the performance I can get until I upgrade :P As for what you were saying about the 27MHz increases, I though the new BIOS locked all 3 clocks to the same frequency?
I wish I could do the volt mods. *cries*
But, after installing my Arctic Silencer originally I got quite high temperatures, higher then what I got on the stock cooler. But when I re-installed the stock cooler I got even higher temperatures. So somehow I have managed to increase the heat output of my 7800GT without actually doing a voltmod. :mad:
I get 45C on idle and 65C on load.
Damnit!
Hmm, maybe I did do a volt mod unknowningly. :p:
*checks highest coolbits clocks*
EDIT: WTF!!!
Highest clocks are 466/1030 WTF
Were 480/1150 before installing the silencer WTF!!
God damnit, the arctic silver that made its way to some of the resistors around the core needs a good clean out....
Was that the only reason for 27MHz being the magic number? I noticed that they always were the same, but they wouldn't always run at the specified speed. I can't exactly remember an example, but like I'd set the core to 555MHz and the true clocks showed in Riva Tuner wouldn't budge until I hit a certain speed. Sometimes they'd even round up. I've just heard everywhere that 27MHz was the magic number. My understanding is that 27MHz is the reference clock kind of like a divider. I guess if they're all locked though I could try for a few more MHz. Good luck with your water cooling and I hope your memory clocks improve. I feel sorry for Bob and his Arctic Silencer... What kind of thermal paste are you using?
Bob's dead, no need to feel sorry for him. :stick:Quote:

Yes I am, I even reinstalled the stock cooler and the stock cooler showed higher temperatures too. I've also got a VF700-CuLED sitting around because it's worse then the silencer.Quote:

I'm sorry to hear that, I don't think there's any real solution to fix your problem. I know the silencer uses a totally different mounting system than mine, but I'd think the Zalman was similar, when I first installed this one it took me alot of time to figure out the right tension on the diagonal mounting bracket. If I didn't get it perfect it resulted in temperatures hitting 90 degrees, obviously I quickly closed ATi tool everytime I failed to get it seated correctly, but still. Have you checked to make sure that the goo is getting sufficient contact to the core? Try putting the TIM just on the core and then press the heatsink on, pull it off, and check to see how much it spread out. If you're doing it right I don't know what to say.
I had a silencer with my 6800GT and it was horrible, after 15 resttings and a whole lot of AS5 wasted I bought the VF700, couldn't be happier with it, now my MCW60 is in ;)
Hey Guys,
Long story short guys I accidently broke my 7800GT when removing the GPU voltage mod because I was selling it. Since it broke the buyer did not want the card anymore (who could blame him). So I still have the card and now I want to fix it.
I did the same GPU voltage mod that everyone has done using the 5k or 10k variable resistor (VR). The one where one leg of the VR gets soldered to a ground and the other leg gets soldered to one side of the corrent capacitor.
Well when I was removing the votage mod to sell the card I accidently broke off the correct capacitor and lost it. The cap broke off very cleanly and I think there is a good chance I will be able to replace it without much problem. The only thing I need to know is what value that capacitor is so I can get a new one.
With that said does anyone know what the value is of the capacitor used in the 7800GT GPU voltage mod? If not, would someone measure it for me with their multi-meter? I have looked through many threads here and over at XS Forums looking for high-resolution pictures of that area of the 7800GT but have found none that wouuld clear enough to see what the value was on that capacitor.
I just got a new 7900GT that unfortunetly needs to be RMAed so I want to fix my old 7800GT so I will have a card/computer to use while my 7900GT is away at eVGA! Thank you guys very much, I apprecaite your help!!!
I had a vf700 with my 6800GT, and a NV5 silencer Rev3 with my 6800GS.Quote:

Unfortunelty I now have to RMA my new 7900GT because of some major artifacting, random reboot, shutdown, BSOD, etc...problems so I want to fix my old 7800GT so that I won't be without a computer while my 7900GT is being RMAed (Even though it will probably only take a week or so).
To fix my card all I need to know is what value that resistor is (the one I accidently pulled off while removing the voltmod). I will just replace it with a new resistor. It broke off pretty cleanly with good solder pads left over! Unfortuently I lost the resistor when it broke off so I have no idea as to what value it was.
Would anyone be willing to check their 7800GT for me and measure the resistance value of this resistor so I can fix my card! I thought about maybe just using the variable resistor I used for the voltmod but I'm not sure if it would be enough because it was used in conjunction with the resistor on the PCB? Below is a picture on the PCB with the resistor in question circled to make it easier to know which one I need the value for! Thank you guys very much for taking the time to measure this for me! I owe you one.

If you broke your card while modding or unmodding it's not the company's fault and you should take responsibility for it, not make the company pay for it (which will drive up prices and hurt everyone else).
I hope your not replying to me as I didn't say anything about RMAing a card that I moddified. I know it's a long post but if you read it you would know that is not the case. I am trying to fix my old 7800GT which I broke while modding. My 7900GT is defective and has never been touched. In fact I was not even able to overclock it because it would just lock up and reboot, artifact, BSOD, or just freeze until I manualluy rebooted.
The picture included in the above post is a picture I copied from this thread to show the resistor that I need the value of so I can fix 7800GT. Please read through the post before you post a reply please. I feel the same way you do about people RMAing cards that have been messed up by user and not the manufactuing company. I think that is also the reason the RMA process has become such a pain in the ass sometimes. Any chance you'd be willing to help, do you happen to have a 7800GT? Thanks all the same!
Sorry about that. I really should read posts after I shower (I just woke up). Read your post again and in the first line it says that you bought a 7900gt to replace your broken 7800. /smack_forhead
EDIT: my 7900gt is my first nVidia card. If I had a 7800 I'd be more than happy to rip er out and checkout that resistor for you.
Hey guijonsith,
Now I feel like a jerk for replying to you the way I did, it's just that I feel the same way you do and didn't want to be thought of as someone who expects companies to fix my mistakes, but thanks for trying to help! So I take it your happy with your 7900GT, what card did you have before that one?
I'm working on my card now that my water cooling is up and running, card idles at 31C (or lower, temp sensor innacurate?) and loads at 35C
This being said, what was the max safe voltage on water? 1.7? :stick:
If a delta BIOS doesn't help me unlock this card, 1.7v better ;)

Thank you very much Nosfer@tu, it would be awesome if you had the time to measure that resistance value for me! My neighbor has a pair of 7800GT's but they are XFX's and the PCB layout is totally different? I sent you a P/M, thanks again for your help and time!
Sorry for my English. Why, when I connect 25K to chip in my 6800GS i don't see changes on multimetr (before 1.4; after 1.4)????
Welcome to XS forums, and dont' worry about your English it's fine! When you say "I connect 25k to chip in my 6800GS and don't see changes on MM what voltage mod are you doing? That is what info are you using to do the voltage mod on your 6800GS card? I only ask because I'm not familar with the process for your card.
1.4 Volts would point towards a CORE mod not MEMORY mod, I think you need double check its correctly grounded (earthed).
I relied to you PM.Quote:

I would say the resistor is 1340-1371 Ohms.
My MM is a Monacor DMT-2560
Specs here.

How's this for memory cooling?
The aluminum is 3mm thick, sinks epoxied on it, been kind of generous with the epoxy but well, it works :D
This is meant to be screwed on the card, so you can use normal paste, always comes in handy when things can be removed without pulling your bga memories off in the process eh? ;)
It wasn't until I saw the pictures that I knew exactly what you were talking about. I'm pretty impressed Garrett, great job! Did you have a chance to install it yet on your 7800GT and if so how did it go?
I just did a 1.55v mod on my 7900gt with a vf900 on it and my temps are getting up to 74 deg c. Is that ok? or is that high for a vf900?
1: cloud, this thread is about the 7800gt. You coulda posted in one of the 7900gt threads or started your own
2: that sounds high for a vf900cu. how's your case airflow? how cold is it in your room? Good air flow with fresh cool air is a must.
oops, read the thread wrong. My air flow shouldnt be too bad. I have a thermltake armor most of it is filled with hard drives. It just hit 80 while running 3d mark. My room does get pretty hot. My vf900 did have one of those holes that didnt screw in right. it never fully tighten and kept turning. I still manage to attach the heatsink find i just had to hold that stub with a piler and turn the thumb screw. As far as I could see it was pretty tight. Could that be an issue?Quote:

yeah 7900gt dead. Went to try to reseat the heatsink and now it is artifacting when im starting up the computer. Doesn't acutally get into windows or it does but nothing really shows up. Popped in my old card and it was fine. Question is the card suppose to be bent a bit when the heatsink is installed? Also am I better off doing a RMA or get call evga and get them to honor their warranty?Quote:

Does anyone know if you can adjust the voltage of the cards during operation with the pentiometers? I've always shut down the system, tweaked it, booted, and repeated, I am just wondering if the other way is safe
Yes, at least I do on mine. Monitor V with DMM during adj.Quote:
