Mat_Agnesi Posted March 29, 2014 Share Posted March 29, 2014 FRANKESTEIN CARD, this is an 8800GT with the 8800GTS's Power supply. Made by me from two broken CARD, the 8800GT has broken VRM, and the 8800 GTS has broken CORE. Both Core and RAM is powered by the external 8800GTS's power supply. Very Crappy Qimonda RAM can't Overclock more than 1060MHz even downvolted... Quote Link to comment Share on other sites More sharing options...

Guest BarboneNet Posted March 30, 2014 Share Posted March 30, 2014 very nice solution!!! hai usato la gts come epower? grande.... Quote Link to comment Share on other sites More sharing options...
nachtfalke Posted March 30, 2014 Share Posted March 30, 2014 (edited) asus 8800GT top don´t need another vrm , because it have one enought powerfull for G92 chip . it have L6713A pwm ..just moded fb pin and ocp mod . the "secret" is to put a jummper or dip switch on the FB wire ...boot in windows with jummper removed ( without FB mod- on), and then in OS put the jummper back ..then you will be able to inceerese voltages ...without OVP trigger... for the mem , you need REVERSE vmod , because qimonda ic´s are very difficult to bench with lot of voltages , need degreese the voltage ..just moded the FB pin to + vram vrm output , and you will be able to reverse voltages .. measure before the ressistance between the fb pin and out+, and then put a trimmer x 20 over that value good look!

poparamiro Posted March 30, 2014 Share Posted March 30, 2014 Those 3 phase need good cooling and can sustain 1.5v+ an air/water, no nned for zombie (if the card VRM is OK, of course). Even two phase VRM with very good cooling can sustain a G92 GPU with big air voltages: Check below: http://hwbot.org/submission/2345165_poparamiro_3dmark_vantage___performance_geforce_8800_gt_256_mb_8975_marks If you have e golden board with defective VRM, is wothed to zombified.

Mat_Agnesi Posted March 30, 2014 Author Share Posted March 30, 2014 Thanks everyone for the interest. My custom power supply cutted from the 8800 GTS is modded and has a wide range voltage regulation. GPU voltage can be set from 1,1v to 1,8v. RAM voltage can be regulated from 1,5v to 2,3v. For that crappy Qimonda RAM I've used 1,9 volt, and for the Core 1,45v In fact, nachtfalke & poparamiro is right, not so much difference in overclock between the original Asus's power supply and my 8800 GTS's power supply. RAM stop at the same frequency, The core can go only a little higher than before and need a lot of voltages to raise more. what voltage do you usually give to that G92 chip ?? For sure, this is not a Golden Card...it's crappy, right ? but I have liked that experiments, it's funny. Quote Link to comment Share on other sites More sharing options...
ludek Posted March 30, 2014 Share Posted March 30, 2014 I like this! Is it 4 phase power section? The same as 8800 GTX? I have my 8800 GTX zombie, after tunning it can do 4phase: 1.3 - 2.6V, 2phase 1.7 - 4.2 V. It is very stable and helps me lot! I also like experiments like this!

Mat_Agnesi Posted March 31, 2014 Author Share Posted March 31, 2014 The PCB has a total of 4 phase, 3 for GPU and 1 for RAM. This came from a 8800GTS, I think 8800GTX has more powerful power section. however, this one that I have has supplied also my AMD HD 6850 (little overclocked) without problem ! not bad for that old mosfets Quote Link to comment Share on other sites More sharing options...
