Damn macci 34 marks from 10k woot :D
The name fits is right! :pQuote:

It's called condensation. Take it out and get a room heater and blow warm air on it for a couple hours. Sticking it in the oven helps also. Watch the temps though. After it's dried use alchohol and cotton swabs to clean the whole card. Also the agp slot may have condensation as well. You'll need to make something to stick in the slot. I use a piece of cardboard from a box and alchohol. I've had cards that wouldn't even turn on come back to life doing that btw. Don't RMA a card that isn't dead yet. Yours was probably just fine and just needed a toweling after it's bath. :)
interesting that you think it`s condensation, but I don`t think so.
This is the third card I`ve had frozen now and I`ve never had a problem with condensation at all. I always use the heater tape around the core and set it to 100%, never had a bit of problems. There too, after I removed the card I cleaned it throughly with Brake and electric motor cleaner and then blasted instant dry with compressed air before I put the factory heat sink back on, and tested again, I don`t know if you`ve ever seen that cleaner dry under compressed air before, but there would be no moisture after that.
Inspecting the card closely, it looked to me like I might have marked/crossed connections (possably?) the printed curcit board by\next to one of the attaching holes, there are like 4 tracers that pass real close to the hole, looks like I might have damaged them when I tryed to pass the threaded rod thru to mount the Vapo head.
Whatever it was that killed it, I`m sure I did it. :rolleyes:
Hmm i use a electronic spray cleaner that has excellent dielectric properties. It won't kill ESD sensitive parts and dries quick. Mine is safer. But it seems yours works fine. I've cleaned and cleaned and cleaned until i thought all the water was out. On the really pesky cards i've had to wait 2 weeks before they came back to life. But if those traces are messed up well that's another story altogether. I rarely kill a card for good. Although my R9800Pro2 with 256mb a saphire died with no o/c and no V mods. It was my stock card for gaming only. Died in the middle of a game. So it sometimes doesn't take much to kill theese things. We might as well v mod and cool em and o/c em if they die stock. If it's gonna die it's gonna die.
You the man! :) Well, I changed to 4.2 drvrs and got about 40+ points... then after that session, I shut down and pulled the card from the Mobo ( I've been fighting condensation ) I think I finally got it! Everything looked good and no H20! :DQuote:

I took the backside insulation off and measured R1596 @ 41.2k ohms ...I penciled it to read 19.52k ohms and this morning I reinstalled the insulation. Ran it up ... This is very interesting!
The card is much more stable! The sparkles are reduced and I can run higher vcore ( I'm @ 2.125 now) but, I can't get the clocks any higher ..... the card is alittle hotter .... graphics are cleaner... but stuck with the same clocks! Hmmmmm, I'll keep at it because it's diffently better, just different! ;)
btw, #4, Runmc is pretty safe I'd guess, unlessssss :p:
OK i fixed my channel 2 of the gpu v core. Now i don't burn my finger on channel 1's inductor. Only problem is i got the sharing incorrect. Channel 2 is taking like 60% of the load. But at least nothing gets hot any more. I'll fix this tomorow to run channel 1 and 2 at 50/50. er i hope or if anything to get channel 1 to run 60% or so. It's supposed to take a higher % because of the volts going to hexfets it can actually put out more ciurrent.
ok what's the highest o/c with a heatsink/fan? Got mine up to 540 now with all copper socket 370 heatsink/fan and ambient temps are about 25C. Almost time to install my water block again. :)
Oh and total v mods just to gpu core is up to 7 now :)
Now that all the big boys are here, Can someone help out with the Vref mod. A pictue would be greatly appreciated. I am sure this is what is keeping me at 405Mhz on the mem. Both Hobocrow and myself have been posting asking for help and yet to get a responce ( except for penciling random resistors)
Thanks-Crusher
Instead of pin 5 to ground try pin 5 to Vref. Same for vddq as well. That's one way to do it. Or search for the resistor that reads Vref and about 800mv and ohm it out and figured out what size vario you need. Vref is harder to fake than vddq. So finding the correct resistor is most important. I didn't write down which resistors they were and i mod em slightly different than above.
Oh and the calculations that work best for me are as follows.
Vref=(vddq/2)+.100 to .125
i've tried raising and lowering vddq and setting Vref accordingly. Best seems to be vddq set at 2.65 or so. Lower is better than higher btw. But that's just me.
Random penciling is the sheit. :)
Oh and that was to lower Vref and vddq. To raise them use pin 5 to ground. The controller chip for Vref is closest to the molex connector and vddq is closest to the agp slot. We already know where VDD is at. ;)
I've been trying to find my old notes from the 9500np and 9800p mods.... looks like I keep worst notes than you. :) So, iirc, the VDD, VDDQ and the VREF controller chips are (ICxxx)s with the same #s. Of the lower two the upper one is Vref and the lowest one is Vddq. I cann't get to mine as it's under foam again.. anyway's I'm reluctant to do it as it's a card killer if you do it wrong!Quote:

I think I'll just lower the resistance on R1596 and up the volts a bit instead! ;)
Very good description. Yes it can be a card killer if done wrong. However i've always believed that V modding was needed to keep from frying a card. If the volts are wrong when you o/c you can fry it. I try to find the correct volts and set it accordingly then o/c like mad. I feel this saves my cards. This was a MUST on the ati R8500LE 128mb cards and a couple others. Incorrect stock Vref killed those cards. Not my opinion it's a proven fact. My R9800Pro2 256mb card died because it didn't put out enough watts for vddq or Vref i forget which. Both cards died with NO o/c or V mods. ATI if you noticed must have hired someone else to design thier boards. I've noticed thier voltages are much improved. At least now they won't get thousands of returned fried cards because they can't even figure out the correct volts and watts. The R9800xt was designed extremely well imo and whoever designed the board for it should feel extremely proud. It's thier best design yet imo.
Oh and what is MAX gpu Vcore anyone can run reliably? 2.275 is max on mine. Although i can run it higher it doesn't help any. Macci has his up to 2.28 Just slightly higher than what i run at. Since i did a few more V mods to gpu core i may try 2.40 or so. But not with this heatsink/fan on it. It just doesn't like to run above 2.225 with heatsink cooling. hehe that's some wicked volts for lame cooling. :)
Couldn't we ohm pin 5 to grd off the IC for Vref and then put a VR of the appropiate value so as to be able to either raise or lower Vref? Or is this thinking just silly! :D If it would work then maybe Mrcrusher could ohm it out for us!Quote:

Measured Pin # 5 on Vref IC at 1K ohm to ground and .800volts when powered up. Right in front of the IC there are 2 pads, the one on the left measured 1.41 volts (Vref???) and the one on the right measured 2.65 volts (Vddq).
The two Caps to the upper right of the IC measure 2.85 volts which is my Vdd and the other measure 2.65 volts again Vddq??
See picture below
I can't believe you told everyone in the world about this catch.
jeeeezz louiezzz. what came over you???

I couldn't agree with you more.
Simply a little humor between catch and myself;)
Kinda catchy the way you spelled purpose. How long did you think about that one??
Simply a little humor betwn us... didn't take long at all... a lucid moment! :DQuote:

MrCrusher... :) This is good stuff and sort offfff what irc! :D We'll just have to wait for C22@play to get off of holiday and find the time to post back! ;) Maybe, we'll all get higher.... modded the C22@play way!! :cool:Quote:

I'm just playing a game. I been checking this thread every few hours.
Runmc hehehehe. It was getting boring in that there are less than 10 people at 9k+ 3dmark03 scores. I think your score is fairly safe.
Hobocrow if memory serves we've been talking back and worth to each other since the r8500 days at rage3d and P3 days at overclockersforum. Nice to see you at the top of the field after all theese years.
MyCrusher you got everything correct. You can remove the ??? marks now. Only problem you have is your volts are pretty good. Maybe try raising Vref just a bit to get rid of sticks on wings. Set ddr o/c to 405 or so. Gradually increase Vref to a max of 1.450 Try small increments cause it's very picky. Try 1.410 then 1.415 and so on. As you increase this it should help. Raise ddr o/c and repeat procedure. Usually when i have mine set correctly i actually have a couple dots on my desktop. What actually seems to work better is lowering vddq and leaving Vref as is. Here's an easy way to lower vddq.
look at your pic from pin 5 of vddq's isl6522 chip we want to use a 100k ohm vario to pin 5 of the hexfet located next to it. Pin 5 of the hexfet is next to R934. Set the vario at 100k ohm. Pin 5 is vddq out btw. It's always a good idea to solder in a 1/8th watt resistor say 100 ohms to any vario you use. That in itself can save your arse.
I think if i showed all my v mods we'd have 50 people with 9k+ scores. The most important v mod of them all.
GET A PCPOWERCOOLING PSU!!!!!!!!!!!!!! :)
OH and since all theese R9800xt's are made with different parts each will need to be modded differently. I have another idea i may try tomorow night for ddr. But as you can see i can't tell you exactly what will work. I've had people try theese things for thier ddr with zero gain.
I'd show you a pic of my card. But if i did that without complete instructions you'd be very confused and you'd kill it for sure. I got 16 gauge wires going here and there and some parts completely removed and some replaced.
Hey C22... your right! :) I owe all my VC ocs to you... Your the man!... Com ovr here... I'm gonna hug ya! :p: RGds ... :toast: HCQuote:
