Dell Precision M6700 Owners Thread

Well I had an unlocked vbios on the k4000m that per the synthetic benches, after a pretty large MSIAB OC +60% of stock, turned it into somewhere between an 860m and 870m. My guess is that the 970m is about 30% more powerful than an 870m in line with how nvidia does generations usually. So I'd say about 35% more for the 970m vs the k4000m OC. All this is firestrike metrics, didn't do games benchmarks at that point. It's a pretty nice upgrade for older card trading.

Then a 980m is about 25-30% more than a 970m. My current 90w 2060m is about the same as a 1070m, about 70% more firestrike score than a 980m.

 

Tangential, but I did a lot of K5000M to M5000M comparisons and looking at an at least 2× improvement in almost all tests. I would think K4000M to M4000M would be a similar improvement, percentage-wise...
(I did overclock the K5000M back when I was using it, but for these tests I was running it at the stock speed.)

Hi everyone, sad news, my GTX 970m died. I saw that some people got the Tesla M6 to work, but with having to mod the vBios, is that something you only have to do on the M6700? I saw a link on here going to a tutorial on how to get the Tesla M6 to work on an M6800, no mentions of a vBios flashing on any of the text.
I really want to get a pascel card if I can, I see people mentioning that you can get engineering samples of the vBioses there, but where do you source them? I look on google and I can't get any results back, unless I am not looking hard enough. lol

 

You should be able to find the vBIOS'es that you need for Pascal cards in the M6800 GPU upgrade thread on here. Note that we only have them for P3000/P4000/P5000. Also note that you cannot perform the flash on a M6700 — without an engineering sample vBIOS, any OS will fail to boot. You'll need another system or a hardware flasher. I tried P5000 in my M6700 and it "worked" (I used a M6800 to flash it) but it would BSOD every few days so I had to get rid of it.

Tesla M6 and all Pascal cards will only work with Optimus turned on.

 

I guess I will only go with the Tesla M6 then, there's no Vbios mods I have to do for that, just follow the tutorial that's a few pages back? It looks like a pretty straight forward install if there's no vbios you have to flash for the Tesla M6.
The issue with me being able to flash the M6, as well as quadro cards, is that I don't have any working laptops I can put it on and most quadro cards doesn't allow you to clip a EEPROM programmer on it. : (

 

I finally received my M4000M and tested it against the K4000M. Seems like quite an improvement:



I want to push the M4000M memory up but there doesnt seem to be a custom VBIOS that allows memory overclocking. I cant seem to get proper core boosting past 1220mhz either. Still a pretty nice upgrade.

 

I am not experiencing a weird problem. With the K4000M I used to be able to output 4k 60hz or 1080p 120hz to my Sony X900H TV. Now with the M4000M and the exact same hdmi cable, the laptop refuses to see the TV as anything beyond 1080p 60hz capable. Tried with both Optimus ON and OFF. Forcing a 4k custom resolution doesnt work (TV goes all crazy).

Is this a driver issue? How can I get my M4000M to see my TV as 4K again?

Thanks all.

 

Seems odd to me. The Kepler cards have HDMI 1.4 which is 4K/30Hz only. Other users have confirmed this limit on the M6700. (Need HDMI 2.0 for 4K/60.) You should be able to use higher modes with a DisplayPort -> HDMI 2.0 adapter. The cards have DisplayPort 1.2 which does support 4K/60. (It should be able to do 120 Hz 1080p on HDMI 1.4, though.)

Maxwell does support HDMI 2.0 but I'm not sure if there is some other limitation in the M6700 that would prevent it from going up to that level. (The HDMI port might be attached to basically an internal DisplayPort adapter.) I'd still recommend trying with a DisplayPort adapter.

 

Agreed, I was very surprised that 4k 60hz and 1080p 120hz worked. I tested them with UFOBench and the 1080p 120hz mode worked perfectly fine though. HDMI 1.4 fully supports 1080p 120hz.

Regardless. with the M4000M it cant even tell that my TV supports 4k. It just says maximum resolution capable is 1080p 60hz, which is really annoying. The installed driver is a Generic PNP monitor driver from 2006, and I think the driver is the main culprit here. Previously my K4000M was running official drivers.

Are there any special NVCleanInstall settings I need to use to allow proper monitor detection?

EDIT: Its definitely a bug with the modified INF driver for the M4000M. I tried with another hdmi 1.4 laptop and 1080p 120hz works fine. I tried the M6700 with a 1440p ultrawide and it wouldnt output past 1080p.

 

...Did you modify it yourself or are you using one you found somewhere?
