Hey guys, planning on having a play with tri sli should i get another asus card the same as my other two or a reference card?
post #21043 of 24922
Hey guys, I've been OC'ing, and right now I'm using PX 4.2.1

I've heard good things about afterburner (especially since PX 5.0 got taken down and doesn't really have an ETA for being back up) but I was wondering if it had an option similar to K-Boost like PX has, because thats really useful for me with some games that just dont seem to boost right, and it seems like it might be a good move to go to afterburner since I'm using an older version of PX

Hello , anyone can help me ?
I have one GTX 780 HOF+ with chip B1 and i saw with HWINFO program, the controller is CHL8318.
I tried to unlock the voltage but without result.
I had flash the skyn3t Bios for B1 and i've tried to unlock the voltage with Afterburner but it's said Invalid.
Where i wrong?

Regards

Hey guys I've just completed my first custom water loop & water cooled my GPU's for the first time ever aswell I used alot of information from this thread to help with my overclocking and flashing custom bios etc

So I wanted to share with you the results of my time and money spent smile.gif

Here's my finished build



Specs:
Processor: Intel Core i5 3570k @4.5Ghz
Motherboard: Gigabyte: Z77X-D3H
RAM: 16GB Corsair Vengeance LP 1600MHz
GPU: EVGA Geforce GTX 780 x2 (Overclocked + skynet custom bios both cards running at 1314mhz)
PSU: Corsair RM1000
Cooling: Swiftech h220x + 2 EK 780 Nickel Waterblocks + Alphacool 360mm Radiator
HDD: 2x Green Western Digital 1TB drives
SSD: 120Gb Kingston SSD
Case: NZXT H440 Green Edition
Monitors: Samsung 27" U28D590 2160p Monitor - x2 24" Benq GL2460 1080p - 32" LG TV



I currently have both my cards running stable at 1314 mhz core clock and 300+ memory clock with a voltage of 1300v and 150% power target running skyn3t vBios rev 3A




Unigine Heaven Benchmark results: Ultra Quality, Extreme Tessellation, Resolution:3840x2160, 0XAA

Both cards running stock:



Both cards running OC:



And finally my Fire Strike Score



Thanks for viewing smile.gif

If your GPUz pic is showing core clocks and boost as 2 different values, then its not our bios, as when boost is disabled its the same value as core clocks! wink.gif
So you must be making a mistake with the bios you put inside the folder as x.rom, it really happens a lot! wink.gif

Yes it's non-reference as it uses a different set of VRM's (Voltage Regulator Modules, or Power Decoupling and Capacitance Banks as i like to call them as a homage to master TIN! smile.gif) with more power phases that reference cards!

Another thing i did get one bios to work when i did it the first time and everything worked, OC worked great and all. it wasnt till it crashed on a benchmark that i started having issues like with the bios and the BSODs (which you explained already why;) ).
i mean my bios revision is 80.10.3A.00.80 and i have an evga 780sc acx. what would be the right bios then?

My question is what is your original stock bios? If you bought your card new as of lately its bios 80.80.xx.xx.xx if its "old" ( or used card) as in since last year it could be 80.10.3A.xx.xx
Look at the back of the card for a sticker with your bios revision on and report it back! thumb.gif

Careful with PT slider, only increase it if you are experiencing stutters or frame drops as you see your power draw constantly hitting the max! Leave it at 100% and increase it gradually! thumb.gif
As you are actually allowing more current inside the card a spike might generate enough heat to burn something ( less probable with EK blocks and ALL inductors covered with thermal tape but STILL probable that something might give in... wink.gif )

My take is always EVGA as for its RMA policy! "Always looking ahead and around the corner!" thumb.gif

With AfterBurner you can do the volt mod ( in my SIG) it allows you to set the voltage up to 1,300V) PX only to 1,212V with K-boost! wink.gif

You are using the wrong guide, i have two guides, one for the reference 780/Titan and another for the DCUII but it might work with the HOF as it has the CHL8318 voltage controller!

Here its my guide for your card:
Quote:
"For those who want to try it AT YOUR OWN RISK


VOLT MOD FOR ASUS GTX 780 DCUII with Voltage controller CHL8318 up to 1,300V

Go to profiles folder inside Afterburner folder :



Now open the: VEN_10DE&DEV_1004&SUBSYS_27843842&REV_A1&BUS_3&DEV_0&FN_0.... files inside the profiles folder and add
these lines:

[Settings]
VDDC_Generic_Detection = 0
VDDC_CHL8318_Detection = 44h

Now save and close notepad and restart Afterburner, it will ask you to reboot!"

Still it might not work for the HOF, if you are using Afterburner 4.0.0. beta 9 and it doesn't work, try the Afterburner 3.0.0. stable final : http://www.guru3d.com/files-details/msi-afterburner-beta-download.html

Just be careful with the power draw at 150%! thumb.gif

Thanks, so im guessing 150% is too much what power draw would you recommend? :s

Drag and drop the file to desktop, change it and drop it back to teh folder! Thats it! thumb.gif

OR

Use this little registry hack to add to your mouse right click menu a "take ownership" tab to quickly "own" any stubborn file!

If your bios is 300W based with 150% you will have as a "ceiling" power draw 300W x 150% = 450W Your air cooler cannot cope with it only water and still its dangerous if your card has high leakage! wink.gif
Always keep it at 100% and increase it gradually when you see stutters and frame drops with your power draw hitting max constantly!

Okay thank you very much I've never fully understood the power target I was just always told max it and forget about it, ill do some testing tonight at 100% and see how it performs
