the Nature is to low at those gpu´s clock
, LOD and GT aren´t right for best effciency -
if is compatible with 1366 , is also compatible with 2011lga:D

100€ !

unloaded -61 -62 , load Gt1 -62, gt2 -60 -61 ,gt3 -58*, gt4 nature -55*
it is a mitsubishi rotary compressor 24ccm
, also the condenser is big cooled by 2 fan´s 22cm , evaporator stepper 42mm/50mm made by bartX , this ss was designed by me for heavy load , i will build another one i hope more powerfull:D -
i´m glad that you like my work:D you need to find 512mb version no 1gb , because qimonda 40x ic ram´s on this pcb design are very good at ram clock.
here the mod: http://forum.lab501.ro/showpost.php?p=357173&postcount=228
if you need advice in deutsch sprache please PN me.

thanks! the SS can handle massive load , it was designed by me for that
Asus HD4870 top/ dk / matrix are from far the best design , but you need vid mod , also i tested the pcb power plane and is very strong compared reference or sapphire card´s , that is the point because i like asus custom vga´s
also the result is not max , because card can run 1130 / 1275ram , and with little bit cpu ower can be a great result!

new price: 110€

bump!

the pwm is RT8841 with FB pin6 , you will have ocp trigger if you go higher ( 1,55+) but also can configure the ocp from pin9( imax) no problem
the memory pwm should be RT9259 ( i can´t see good in the pic´s)with FB pin4
-
the really problem on L6713A pwm is the OVP:)
first configure the FB mod and see were is the ocp trigger value , then configure the ocp from my pic ( you can tryed from 5k to 3,5k , for me 4k offer 1.5 - 1,55v enought i think).
ocp mod offer you 20-30mv before ovp shut down the card ,and then need ovp mod .
the best way is vid mod , but i don´t have time now to configure vid mod, please try in this way and post here.

the board wasn´t tested for max bclk or oc capability , it was brought for my 775lga collection half year ago

not that BIG btu´s count mate..because the limit of refrigerant´s push with one 10-12k btu ....for example R507a have -47.1 boiled points , R404a -46,4 ..most phase change builders push the discharge pressure over safe limit to get that lower temps ..but in 1 year( or less) you have a death compressor.anyway nice score and nice cpu , again!
cheers!
-
-60 load for a phase change unit is little bit out of range:D
nice cpu:D
-
i think the mb is s**t at cpu clock
nice score , monster vga:)

have you tried the CB bios from here: http://forum.hwbot.org/showthread.php?t=26163 ?
-
Thanks guys, this was an hard Job to beat Mtech
ofcourse it was , becouse you use wrong driver ..
-
if you look for heavy bench unit ..the compressor / condenser and refrigerant( R134a have a low performance ..for what you need) is the problem, the water pump also( need MAGNETIC PUMP) , becouse the pc designed for water is not perform very well at lower temps.
recently i build myseelf a strong chiller and GPU SS with rotary´s compressors( both with R507A)! , for exemple my Chiller loop is with the evaporator builded in reservoir ..that offer a better boost compared with HX plate ..that all chiller/ss builders use today.
HX plate is restrictive over -30* water temp, liquid into HX cover small amount of water ..and that make it unstable at load temp..etc..
i waiting suction line from BartX and i can braze hole unit an ready to go:D http://forum.lab501.ro/showthread.php?p=362036#post362036

is another pcb design , another gpu arhitecture ...the pwm can be scheduled from factory in another way , even you can set up to 1.5 via I2C buss adress with smart dc software i think will have also ocp/ovp problem.
the pwm is SHE ASP0907 ( uP6208 undercover- asus renamed the pwm ) is same like gtx580DC2...
-
does matter..small difference , just give it a try and will see!, desolder the smd´s and then measure exacly the value!
the vid mod area from back side is exacly like in my pic , yes?
-
sure, you can remove resistor 2 and 3 , measured the resistance and soldering a variable resistor set at same value to specific place that in Ramiro pic.
it is another way to control voltage over ovp/ocp limit ( ask elmor )via I2C bus adress , if the mod above is a bit complicated for you
just hint a PM to elmor , i shaw eVC have support for uP6208.

if you made VID mod don�t have that problem with ocp/ovp anymore , is ONLY way to pass over OVP , ocp can be modded via trimmer pot , but he offer 40-50mv before OVP trigger out..so need vid mod.
in fact OCP and OVP have almost same symptoms, both shut down the vga ..0 Volts , always OCP shutdown first and then OVP ( if you have allready the ocp modded before)
unfortunately i don�t have now hd 5850 DC2 ( my oldest DC2 is allready dead), but i know have same pcb design like hd 5870 V2 , fortunately i have here 2 pcs
.i made for you a pic with back side were the ressisors for vid are located!please compare with your card if they are identical
if i compare my card( no vid modded) with ramiro card ..he moved only resistor noted 2 ( moved down )and 3(moved up) .
PS: if you don�t have enought soldering skill , i don�t recommended soldering that area , can be dangerous for vga life
