Overclocking Maxwell?

[Cerberus]

so i flashed the _80 bios, now i cant get teamviewer to pop back up, i restarted the pc three times now (fyi its in a 4u case in a rack)

I take it you have some video output - in that case, flash either one of the classies vbios or back to your original one. Before flashing another 'foreign' vbios though, compare I/O arrangement of the 980 Strix with that of your Zotac Amp.

well, i have been using this 'headless' with a hdmi dummy dongle, think i can troubleshoot this without dragging it out of the rack?

I have 0 knowledge about flashing headless cards. I have always relied on active flashing via admin CMD panel to verify the flash takes. Any of the Linux guys here who use command line text would probably be better equipped to help you with headless flashing. GL Cerb.

i'll pull it out of the rack tonight and plop it on my desk, for some reason the power switch decided to kill itself in this case too, been using a flathead the last few restarts, lol

I guess you're running Windows on the headless machine?  Do you have ssh set up?  You can flash the GPU from a terminal (even on Windows), so if you plan on keeping it headless, I would set up ssh.  I'm not positive if the Windows NVIDIA driver has the bits necessary to OC from the terminal, but you can definitely use nvidia-smi to monitor the card.

 

As far as where you're at right now, the easiest thing to do if you have another machine, would be to throw the card in that machine and flash back to the original BIOS.  It looks like that GPU only has a single BIOS, so rather than blind flashing the card, throwing it in another machine would be the easiest. 

 

Once you're back up and running, I would personally just tweak a stock BIOS with Maxwell BIOS editor, rather than trying to cross-flash.  Unless you have really good cooling in your 4u chassis, you will probably be temp limited before you are volt limited.  The other benefit to flashing your own BIOS to the card is that it will just be a set it and forget setup.  You can just set the card to run at the max stable frequency, power, and fan speed, rather than messing around with clocks and fans from the OS.

Is it true that if you try to flash maxwell in windows that you must disable it in device manager first?

[Avacado]

Yea so I'm an effing idiot. Why didn't anyone tell me there is a voltage protection switch on kingpins? I'll have to remove the backplate and look this weekend.

No, it's not. I flashed the 980 with it being my primary display. Could be different with other cards, but I doubt it.

[J7SC_Orion]

FYI, 'technically', you're supposed to disable the card in Device Manager first before flashing but 'if you feel lucky today', you can try flashing in Windows w/o that...I've done both without much trouble.

 

@Cerberus ...two quick points:

1.) the Zotac Amp model you showed earlier in the thread does seem to have DSP and HDMI outputs. I don't know much about 'headless & HDMI dongles' but to flash a bios, you may want to put it in a system with HDMI output and regular Windows. If you now want to reflash it to the original bios and if you don't have any video output from it in the 4U, put it in a separate system as a secondary card. Just remember that you have to add an additional command to nvflash if it is a secondary card in that system re. 'id = ...'

 

2.) Per my first post in this thread re. Maxwell Bios Tweaker and also per other comments here, modding your otherwise proven bios is far less fraught with missteps than cross-flashing. In addition, the Zotac card you depicted has 2x6 pin PCIe connectors, not the 2x 8 the Asus Matrix and EVGA Classified have (see my earlier post > here). With very-high or even unlimited Power Limit vbios, it cans till work (or not) since 3/4 of unlimited is still unlimited, but your software power readings will be off. Modding your card's native vbios via eg. Maxwell Bios Tweaker is far preferable.

 

Cheers

alright, ill drop the card in my desktop pc, ill post later after thats done on what kind of tweaks I should make

[Cerberus]

so i threw it in my 1080ti pc, and i went to figure out what device id was, this kept happening, try'd two different versions of nvflash.

Command line is wrong. It should be

 

C:>NVflash --list

 

Make sure NVFlash and the .sys file are in your C folder, not in it's own folder.

 

Then whichever is the 980

 

C:>NVflash index=0 980.rom

 

NVM, it shouldn't matter if it's in it's own folder, you had the path right. I am not sure why it's not working.

here is what fah says, also info from device manager

 

 

 

 

 

 

[Avacado]

I have no idea why NVflash is not displaying your devices. =/

[Cerberus]

alright, i just restarted again an it allowed me to flash back OG bios, its back to stock. now what shall I do in Maxwell bios editor?

 

[Cerberus]

alright, got a +400 on memory, lets see if it gives me a boost in ppd!

[Cerberus]

Unstable, lol

We're folding here, not mining...

This is the M2000 stock BIOS if anyone has any ideas of what I should do for tweaking. I don't mind pulling up to 100W from the 75W PCIE slot.

There were so many entries under your power table that I could not 100% identify which was the PCI-e slot. I modified the TDP and power limits to 100000. There were 3 additional entries that were >66000 so I increased the maximum on those to 100000. The remaining entries that were <66000 I did not touch as they would unlikely be your PCI-e slot wattage. 

 

Some of the voltage entries were 1.6mv, I capped all values at 1.281mv. The highest table entry your card had was 1228.0MHz. I changed your Boost frequency from a max of 1162.5MHz to 1228.0MHz. This means that the card can and should hit 1228.0MHz assuming it is lower than the 95c temp cap already assigned (You can set to whatever you are comfortable with) is getting the full 100w and caps at 1.281mv. If you can't hit 1228 or start getting instability, you can set a negative offset in Precision X1 or MSI afterburner for core frequency. 

 

If these settings do not work it means one of two things.

1. The card can't be flashed or did not take the flash.

2. I did not successfully identify and modify the correct power table entry for your PCI-e wattage. 

 

We can revisit 1&2 if it does not work. Please look over the vBIOS before flashing and make sure you are comfortable with it. 1.281mv,100w draw from PCI-e slot and a max temp of 95c are not things that are likely to give the card longevity.

Will look at it tomorrow. Tell me what your limits are. What is the max stable clock you have seen. What max watts and voltage have you seen?

FAH uses p state 0 and i only tried bumping memory up +350 and it wasnt stable. cooling isnt the best but im willing to run the card at 90c as long as its stable and it has some kind of useful folding overclock on it
