    GTX580 Matrix Extreme OC: first session at Assembly

    in Nvidia GPU Overclocking

    Posted · Edited by stummerwinter

    that pot looks so nice, can i have one? :D

     

    Sry, not possible, because to expensive to produce...

     

    SOF! Ehr, I mean, FAIL! :D

     

    Did you test the different FW versions? Any change between 1.8V Vmem and higher?

     

    That 1400 card seems quite solid ... :D

     

    Some cards like or need 2,0 V (I don't have the 1,9 V hack), to run at lower temps...

     

    Well, to be honest the firmware thing is a bit silly. Whoever got idea about it, should have thought twice.

    Card would definitely need a switch with normal firmware and oc firmware. *Hint*

     

    Then it would be perfect.

     

    God hint!

     

    [X] *sign*

     

    :D

     

    I woulnd't use the metal backplate, causes to much condensation...

     

    That's the way I do it...

     

    plastic backplate covered with armaflex and an adhesive rubber foam (~ 3 mm thick) on the front, a litte rubber at PWM:

    slim container:

    and some more armaflex:

    most important tweak...;)

    :D

     

    Great to read...:)

     

    Just to add:

     

    I tested right now 5 cards under LN2 in preparation for GC in Cologne...

     

    1 x 1675/1400 3D03

    1 x 1575/1300 3D11

    1 x 1625/1350 3D11

    1 x issues below -160°C

    1 x not shure, tested different thermal grease

     

    These cards I got from Christian (via Michael) from ASUS Germany, thanx btw, just retail, nothing selected...

     

    Serial numbers: B5CVCM068782 ~ B5CVCM068788 (not all are present for me) and 68843

     

    Found out, thermal grease in combination with container ist a issue, my big container is simly to wide, causes condensation at PWM!

     

    big one:

    slim version:

     

    SLI-Pot-3.jpg

     

    The slim version works much better, but has lack of "cold power", but anyway, 1625/1350 where doable...;)

     

    Agree with MM, fw-voltage tweak ist not a really nice thing, but works somehow. I didn't use tweakit, simply pushed buttons and EVGA-tool to oc...;)

     

    I think, we should work on you insulation...;)

     

    BTW, JP: I failed also while ocing, the card which did the 1625/1350 in 3D11 was not modded OCP/PWM...:D
