Okay so, doing a little multimeter testing again. I'm using Skynet Rev 4 bios, and Classified Controller. When I boost up my clocks and voltage while on desktop (I use 1.275mV for my current clocks)...the reading on the multi is perfect at 1.274mV. Now, when I go in game (I'm currently playing Crysis 3...because well, now I can lol) and test with the multi again I'm getting a steady reading of 1.312. Is it normal for the voltage to jump like that?

No, that was someone else. I was playing Battlefield 4 on stock clocks and stock voltages as the card was degrading severely.

Yes its completely normal. With the classified cards voltage goes up slightly under heavy load to over compensate for vdroop which should help to stabilize overclocks

Interesting you brought up vdroop. I was playing the game fine for two hours, then after a cut scene it locked up. Back to the OC'ing board biggrin.gif

By Heaven Extreme you just mean Heaven Basic with maximum settings?

Metro Last Light (great game anyway) is a good test too, for me it's ~BF4 if not 1 stepping tougher. The bench it provides is good but playing it is better as testing capability.

Odd. I can't get firestrike to even run. It gets to running the system info thing gets my info and crashes before it can even load the test even at stock...

Tried uninstalling all benchmarks and updating driver. No go.

It keeps saying "Expression:hr:DX11 call failed [-2005270523].

Hardware device removed.

DVGI_ERROR_DEVICE_REMOVED: ID3D11Device::CreateBuffer"

 

I also get a message that my display driver stopped responding but has recovered (which is why I did a clean update).

I'm baffled here. Okay I have my core set to 1280mhz (at least that's what GPU-Z says), yet when I run 3DMark 11, Heaven...any benchmark, it never goes past 1267. When I set the core to 1250mhz, it never goes past 1243mhz. Nothing should be throttling the gpu at all. Is this just GPU-Z reading it wrong?

Open Precision X or Afterburner. If you move the core clock slider to +100, then you will boost to 1100MHz (or thereabouts, because the increments go in 13MHz steps). The same rules apply to the memory. Stock memory runs at 1502MHz (6008MHz effective). +500 on the memory will take you to 7008Mz effective. Double the mem offset to get to the effective mem MHz increase.

If you want to start messing with voltage, get the Classy Voltage Tuner in the OP (or you can go up to 1.212v using AB and Precision X if you enable voltage control within the software). If you want a non-boost BIOS grab skyn3t Rev.3 if you have a A1 revision card or Rev.3 or Rev.4 if you have a B1 card. I've posted detailed BIOS backup and flashing instructions within the last few posts. thumb.gif

As a baseline, I think you should be able to get to ~1,260 or so with stock volts, give or take. Some cards are better than others. Move up your GPU offset slowly, maybe ~26 MHz at a time and test stability with Valley, Heaven, gaming etc. After you're done OCing core, then move onto mem. No need to be messing with both simultaneously.


Great instructions. thumb.gif
