Strong Island Posted August 3, 2016 Share Posted August 3, 2016 Hey guys, does anyone have any experience with 285 Classified. KPC is down for right now so I will make thread there also. My stupid evbot died otherwise I would use that. Does the evga voltage tuner 1.1.2.2 work ok? Does anyone know how high can go? Just wondering if I should grab classy or try some volt mods on reference. Thanks Quote Link to comment Share on other sites More sharing options...
nachtfalke Posted August 3, 2016 Share Posted August 3, 2016 you can voltmode gtx285 classified simply like other card aswell ,i did that few years ago! or software with comand line from rivatunner , because it use volterra VT1165mf pwm chip , it is a true digital pwm ...

Wiggles Posted August 3, 2016 Share Posted August 3, 2016 Ill send you a PM about the dead EVBot. Quote Link to comment Share on other sites More sharing options...

There are 2 on ebay Ill send you a PM about the dead EVBot. cool thanks Quote Link to comment Share on other sites More sharing options...
nachtfalke Posted August 3, 2016 Share Posted August 3, 2016 here the mods, be carfully when you will turn the trim pot for vdd and vddq ...they are very sensitive and rise the voltage spontanly, so rotated very very slowly! on gpu , it hint NO ocp or ovp !! enjoy!

Strong Island Posted December 6, 2016 Author Share Posted December 6, 2016 (edited) here the mods, be carfully when you will turn the trim pot for vdd and vddq ...they are very sensitive and rise the voltage spontanly, so rotated very very slowly!on gpu , it hint NO ocp or ovp !! enjoy! hey thanks so much for this. GPU pot works great. Vddr pot works good also. Thanks for tip, even with 20 turn trim pot the volts move the second you move pot. Do you know how to measure vddq? For some reason I get same voltage reading at vddr and vddq measurement points. I tried poking around but cant find any measurement points. On 9800 it was easy, there was separate caps for vddr and vddq but I cant find anything similar. So when I turn the pot for vddr both vddr and vddq measurement points move, so I am just assuming the measurement points are the problem? All resistors I find seem to be vddr and nothing different for vddq Edited December 6, 2016 by Strong Island Quote Link to comment Share on other sites More sharing options...
nachtfalke Posted December 6, 2016 Share Posted December 6, 2016 (edited) they are linked , that way i told you to be carfully when you turn the trim pot , need to be both outputs monitorised also vddq and mvddc don´t respond very well on cold , i don´t think you will need it:D if you wanted to measure directly from vddq or mvddc outputs , on the front side were the vrm are localised you will see one(vddq) and 2 (mvddc) tantalium cap , near inductors!

When I was turning the vddq trim pot I didnt see any movement in voltage, but when I turned vddr trim pot both voltages moved. So it's ok to just use the vddr pot for both? Or does the vddq have to be moved also? I havent really benched a ton of cards that have both rails so I guess that's why I am a little confused. On 9800 it was easy, they each had separate pots and measurement points and I just turned them the same amount. Quote Link to comment Share on other sites More sharing options...

I also figured out a pll mod last night. To the right of the bottom dvi connector on inside. The up6161 ic, pin 4. I measured around 750 ohm and used 20K pot but the voltage was instantly 1.2v, so just the 20k raised it around 30mv Not sure why that would happen, trying to learn. Even 25 times resistance 20k should be good Quote Link to comment Share on other sites More sharing options...

Strong Island Posted December 9, 2016 Author Share Posted December 9, 2016 Tried on cold last night but couldnt break 1152 core 2600 shader. It was weird about in the middle of the bench session whenever I crashed in Vantage, I got a black screen like power off and then like 30 seconds I get a bsod and then a reset. Is that a sign of something other than instability? Wish I would have taken screenshot of 23478 score but I thought for sure I was going to get higher. It didnt seem like the gpu liked much over 1.55v and -130c Quote Link to comment Share on other sites More sharing options...
Strong Island Posted December 11, 2016 Author Share Posted December 11, 2016 had a great time with the card last night, 1188 core, new first place. going to wait for kaby for rest of benches. i think 1200 is possible, 1188 passed on first try and at the very end i ran out of ln2 thanks a lot nachtfalke Quote Link to comment Share on other sites More sharing options...

Strong Island Posted December 12, 2016 Author Share Posted December 12, 2016 Damn !! Very great card !! thanks man, definitely a fun card to bench. I think the first session I was having trouble with the x-cool switch, now I changed the position and the blue screens seemed to stop, I also havent found a cold bug and I only went to about 1.6v so I am excited to push again. Only problem is memory is like 100mhz off top scores so that will be a problem. Quote Link to comment Share on other sites More sharing options...
Radi Posted December 12, 2016 Share Posted December 12, 2016 Same on my classi the memory isn't very . My matrix is better on memory 1500+ but in need to do à vmod because memory is too cold It is the best génération of vga Quote Link to comment Share on other sites More sharing options...

I think you can even leave it un-plugged. Quote Link to comment Share on other sites More sharing options...

Radi Posted December 12, 2016 Share Posted December 12, 2016 i don't think too . i just need to find time for mod and bench it my best matrix is dead now but i have other card no tested Quote Link to comment Share on other sites More sharing options...

I want to max out classy but that memory can really hold you back, so frustrating sometimes. Still fun though trying all these older cards, learning a lot.
