Somehow I get no result when measuring it, the resistor next to it is no problem but that's nog gonna help you.... sorry man, this really sucks but I can't help you, usually I have no problems measuring stuff whatsoever...
Yeah, it is. :(Quote:

Long story short I recently upgraded to the 7900GT to replace my old 7800GT which I accidently messed up when I was removing the GPU voltmod. I actually pulled the resistor that is used for the GPU voltmod out because I didn't take my time. 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 ;)

If so I will shutdown my comp and mesure resistance for you when you reply.
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:

It stops at 1371 Ohms.
I would say the resistor is 1340-1371 Ohms.
My MM is a Monacor DMT-2560

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:
