ah good information man. thanks

[OC_Windforce]

When LN2 tests do you plug in the GPU Reactor (It is very important.)
And...In my&Gyrock case, less than -60 degrees, will freez after the start of the bench.

Thank you so much my friend

Thanks for information and nice results buddy.

Hoping to pick one of theses up next week

How far can I go with the voltage via Afterburner?

[Splave]

1.8v on the core

Do you try adding +100 AUX?

Here is my settings for 1650/1900 (CPU is at 5ghz sorry for blocking it)


Pot at -95c GT1 / -85c GT2 GT3 / -80c GT4 / -75c Physics / -78c Combined
If pot is colder then -78c during physics it freezes the screen but combined needs a little bit more cold to pass

[emertX]

Thanks man!
Without any mods, just taking the oc-BIOS?

[Hondacity]

1.8v is only released for ln2 benchers.

[emertX]

how do you mean this?
I can switch the bios if I want, or not?
Or do you mean the Afterburner? If so...it doesn't matter!

try add aux ..but, Does not change...
My skill is to lack.
Thanks splave

[Splave]

not your skill perhaps your card

5ghz on cpu no OCP on card at that speed, 5.5ghz on cpu I get OCP GT4 every time...drops voltage to .125 till I power cycle psu.
I will see if I can get OCP mod and will post here.

Thanks for imformation

getting my 7970L later.. hope for a good clocker!

[Splave]

this one is pretty nice



-105c for gt1 -100c for gt2&gt3 -95c for gt4 and physics must be above -90c and combined -92c
1.67vGPU 1.825vMEM +100AUX

very efficient run, and cpu is still not maxed

excellent work Splave.

[emertX]

what should be possible under water? Ek is building a cooler!
My water is @ 14°C...other, I mean reference cards, can run 1400 with that...should a lightning be able to do that too?

[Splave]

^ probably not they are meant for ln2 and sometimes do not clock as well on air/water

[emertX]

How are your asics?
So you mean...I should look for a good reference one?

[OC_Windforce]

great works bro!!!!

[SeMbEr]

How are your asics?
So you mean...I should look for a good reference one?

I tested mine card with cold water (idle 10c and max 21c core)
On air my card was maxed 1.2vcore 1200MHz and more vcore didnt help me at all.

On water it turned out 1.3vcore was okey and max clocks were 1350Mhz. (Tested only with 3dmarks)


Hope that info helped u a bit.
Every card wont scare even that much i think but this card could do pretty well with ln2

[emertX]

Mine runs well with 1200...under air and stock cooling...know I'll test a bit with 100% fan!

[emertX]

could you read out your asic?
Mine is comparable...1200 maxed with air...I think water should help a bit, but not much!
