HERE - Try this...

[Hondacity]

my mosfets(with alu sinks) are 36C with fan..drivers(no sinks) are 38C

[Smoke]

Are you guys freezing a bit your VGA's Mos-Fets..I mean heatsinks on them and some air blowing on them?.....

Off course) I use masive radiators on mosfets and air cooling.
I try to freeze my card -76 to -90. Also I have made cap mods. And tried 12,6v to 1,35v vcore
I passed many times 1170mhz 1,2 tests but every time I have blackscreen at Trols((( Nature I passed 1190mhz. I think its OCP problem.

[BenchZowner]

Do both GPU & MEM OCP mods.

[Hondacity]

i'm thinking mem ocp is kicking in really hard...kink has blackout(shutdown) mod..wish i could do it now..

i just ordered tools for removing it...it will be awhile when i get to remove those...

[Smoke]

i'll try hard mods soon.
GTX480 is the wourst card I've ever benched)))

[Hondacity]

its the most power card i ever benched...i love it

the chil controller +driver+mosfets are also really good..no need for caps

[massman]

Just imagine this card on an decent PCB ... can't wait for custom designs!

[Smoke]

Yeah) Cant wait MSI GTX480 Lightning which can ran good without any mods

Caps is also helps stabelise line voltage on hight clocks)
My card

[Hondacity]

nice clean work...

i'm still guessing which motherboard that is...ehheheh

[Smoke]

this mobo only for air test... oldschool)))

[FatAlbert]

dfi lp nf4 sli?

[Smoke]

Yes)

Do you use 2 PSU or if not, have you tried it yet?.... OR VISA-VERSA use one PSU?...

Ram OCP and OVP didn't hit me even at 1.73VRams with no mods.....

There must be something else....



P.S. Please don't ask me how high did I got this card because I won't tell you that it does EASY 1296/1323 at ONLY -120*and 1.32VGPU and I STILL have to get it down to -190*C and more VGPU to feed it..... .

[F.O.G.N.A.]

Thank you very much George, for bios, for the right words and for all work, you are a fantastic clocker and person

Thats just way cool man.

[hiwa]

just a Legend can do this

I use single PSU ANTEC TPQ1200OC

I never freeze this card more than -90, because it have coldboot at -70 and I need more time to try)

Do you insulate ALL the VGA?....
Nowadays Rams are cold bugging like crazy you know....
I used to put 3 or 4 layers of insulation tape and guess what did I discovered with the 5870 one!
NO INSULATION at all as for me for all new cards from now on......

I just plastic spraying them a LOT - BUT A LOT - and I just put the LN2 pot on them and that's it.....

When you fully double/triple insulate them, the PCB get's more freezed inside and the rams runs a LOT colder and they cold bugging....

I encoded this problem yesterday during my tests at full LN2 -190*C and at core frequency 13xxMHz when the PCB around the core took that white colour of snow , reached the rams and then the rams started cold bugging....

In such a case I have to put them on the mod I did as for the 5870 to warm them up a bit....

I'll retry it one of these days and I'll see...

[Monstru]

Will try this pretty soon, thank you old timer

[massman]

George is right. In fact, the worst thing you can do is use that kneaded eraser stuff ...

I insulate rubber eraiser all VGA exept PWMs and other power side... Also I use neopren)
What is plastic spraying?)
I try hard voltmod for Vmem but it is not help to much...

I checked Your new bios. It has bug with overclocking memory. Tried AburnerX and EVGA Presicion but it can't overclock memory. You need to fix it) Also I cached blackscreens in Vantage when core clock was more than 1110mhz.

Why? I use kneaded eraiser about one year without any problem)

[massman]

Because it's a very bad isolator. Cold spreads oh so quickly through the eraser ... it's making the memory coldbug.
