Overclocking Maxwell?

i mean, yeah, is there any point to pushing memory further? also did i score higher than you in cloud gate?

God no. You are off by about 50000 points. Pushing the mem won't make sense for folding, but if you were to game or anything else it would.

@Avacado since this bios is flashed , can we actually add these few mhz? im switching to ubuntu on the 980 machine and i want to keep the oc. should i just run it with the bios thats on it currently? should i try coolbits at it?

After some roadblocks, I cracked the locks on this M2000. I have a slight OC on it now. Now I need to see how much headroom this baby actually has, and how much power this PCIE slot can handle. So far with a small OC it's pulling about 55W and I saw a momentary spike of 88W. Temps nice and frosty now that I put a different air cooler on there.

That's what I'm talkin bout. What settings did you change?

You can add whatever it will take. The voltage and wattage is there. I don't know how much in terms of MHz the silicon will take.

What I did was I dissected the ASUS GTX 950 card's BIOS which has no PCIE connector. I copied over much of the voltages and clocks, but kept my own elevated power limits. Thus it's still recognized as a Quadro M2000, but behaving more like the Geforce cousin. I'm going to let it fold overnight at the 1350MHz and tweak it some more tomorrow.

[BWG]

Holy moly, we're all doomed!!!

[damric]

So far I'm at 1455MHz without issue. Of course HWBOT is down...

 

Gonna let it fold for the rest of the evening and test some more tomorrow.

[damric]

Ok well it looks like it is stable for folding at over 1500MHz. I was able to run 3D benches at over 1550MHz. Anything over that crashes at this voltage. I'm not going to bump voltage as that will probably severely increase the power draw. I'm happy with these statistics I pulled from GPU-Z logs. Even with the huge overclock, it's averaging only 60W and has occasional peaks over 100W. I'm ok with that. Next month it will fold non-stop for ETF, so we'll see if there is a longevity issue with the slot power, but I bet it will be fine. It's still on an air cooler. I have a better air cooler coming, and I do have a water block if I really want to get the temperature down, but as you can see it runs cool already.

 

While this M2000 card itself is too weak to be significant, there are greater implications now if someone wanted to overclock larger Maxwell Quadros now that we have a working theory. I see the M4000s (similar to GTX 970 I think) are going for less than $200, which is still a very good 1080p card for a desperate gamer in desperate times.

You might have more success with the M4000's than I did. I bought a pair of them for SLI benching. I was never able to flash anything on them. If you were able to succeed with the M2000, then you might want to try it. Wish I wouldn't have sold them.

I had to use that flashy thing that bypasses the checks that you linked back in this thread somewhere. It's the only thing that would work for me. Now I'll try that on that GTX 750 and see if I can get anything else out of it with some added voltage.

Yea, maybe I used the wrong NVflash at the time. Figures. There are 3 versions. Regular, ID mismatch and Cert checks bypassed.

I had no idea about any of that. Where did you find the good ones. All I ever saw was the regular one at TPU.

Well I tried modding and flashing Michele's GTX 750 BIOS again. It failed to flash, no matter what version of NVFlash or KBT or MBT I used. It always says sanity check failed. I'm thinking EVGA put some sort of lock on it. I'm not too upset about it, it's already like 40% OC

I think you are probably right. I have come to the same conclusion. I have felt for awhile now that newer drivers were limiting vBIOS tweaking. I would see if you can find older drivers. Or perhaps use DDU, re-start and see if you can flash the card on the default windows GPU drivers without installing up to date ones.
