GTX 1070 on HP EliteBook 8770W DC - it works!

Just as the title says - it works!
I tried one MXM 3.0b GTX 1070 , which I found new and relatively cheap on feebay and it worked like a charm. I did put some LM on the GPU - 73-74C max after half an hour of FarCry 5.
Some pics and benches:





Not bad for almost 7y.o. grandpa....

 

Nice! Looks like a 115W 1070N from the Heaven score (Fire Strike is too low-res to read), which might be the first time I’ve seen a 1070 in standard MXM-B that is not Max-Q.

 

Nice work!

 

Yes, 122W max on load.

 

Nice. Have you tried overclocking yet?

 

It already runs at 85C, no much temp room for OC I think...

 

The card is TDP locked, so OC won’t increase temps, it’ll simply run high clocks at lower voltages. Pascal/Turing OC is quite different from OC on previous architectures. It’s more similar to undervolting.

 

Here it is +200Mhz core OC:

 

Looks good. Your Heaven score is what I expected, but the FS Graphics Score is a bit low (the OCed score should be what it gets at default), I wonder why. Also I would up the memory OC to +500 in Afterburner as well, as the the GTX 1070 is quite memory bandwidth starved due to using GDDR5 instead of GDDR5X, and those Samsung 8Gbps GDDR5 chips are good for at least 9Gbps.

 

Is it possible the CPU to hold the GPU back? (Thats why it gets lower FS graphics?)

 

How do you find it now +200 Core +500 Mem:

 

Nah FS Graphics is very, very light on CPU.

See, there ya go. Nice boost from the mem OC.

 

How much further can those sammys go?

 

Idk much about it, I just know that 9Gbps is supposed to be guaranteed. I would ask @Falkentyne, he's our resident GTX 1070N overclocking expert.

 

Usually between +500 to 700 mhz. There were newer 1060 and 1070 cards with 10 gbps memory that would work at +1000.

 

+600 mem works without problem..
Thanks for the encouragement!

 

Got me wanting further tune my 1070 again lol

 

The temps are a bit high for my taste...
After 40 min “Watch Dog 2” the GPU reached 88C.
What if I modify the vbios with “Pascal TDP tweaker” to pull max 90-95W and reflash it with nvflash? Is the procedure same as it is for the Maxwell vbios flash?

 

You always just tune the card to a lower voltage curve (and lower clocks as a result) to achieve a similar result I believe.

But of course lower tdp vbios would also do that.

The former would just allow for the ocassional spike when an application demands it.

 

Makes me wonder if it'll work without the DC given how hard they are to source, perhaps with optimus?

 

How to modify the voltage curve, would you explain it to me or is there a source where I can read this from?

 

No, because HP 8760/8770 doesn’t support Optimus. Besides, Pascal GPU requires eDP panel, where the normal FullHD non-DC is LVDS...

 

Thought it did, which is why I brought it up. I'd plan to use it with a Zbook 17, which I know does support optimus.

 

You can’t flash a modded vBIOS on Pascal using NvFlash, you have to use a hardware programmer.

The MSI Afterburner voltage/frequency curve editor can be accessed using Ctrl+F. After applying your +200 core offset in the main interface, you can either lock the curve at a lower voltage point using L, or manually flatten out the individual points after that to the same frequency.

 

If I set the curve with ctrl+L, then GPU doesn’t want to switch to low power states when browsing , how to resolve this?

 

Yes that’s what lock means. If you want it to downclock like normal you can save the locked curve to one profile and the regular dynamic curve to another profile, then either manually switch between them or set them as the 3D/2D profiles in the settings, or use the curve flattening method.

 

Still hits 85C...
Time to think about HS mod...

 

Yeah, Pascal is more difficult to cool than Maxwell as its thermal density is higher.

 

Is there a higher CFM/RPM fan for the 8770W? I've heard people speculate that the Zbook 17 G1/2 fan is higher RPM, might be mistaking it for the 8740W fan however

 

Ok, 69-70C at 1418Mhz
What are your settings?

How much voltage needs your gpu at your game frequency?

 

Try to aim for 1550 or so, you can probably keep it around 75C

 

1607Mhz - 69C
It is really confusing with OCing Pascal gpus...

 

Essentially you want the highest possible frequency at the lowest possible voltage, assuming it’s stable ofc (doesn’t crash or degrade performance).

 

Would u mind to share your achievements with 1070?

 

wow! do you have a link for that card?

 

Sure, here u are:

What do you think of this? - 1645Mhz at 0,794V on LM:

 

Definitely not half bad, any reason you havent hit 100% on GPU utilization or is that an FPS limit?

 

Yes, I use v-sync in games as I have OCed my DC panel from 60 to 72Hz and I don’t like screen tearing..
Is this particular 1070 sample a good one as it operates on default clocks only at 0,794V? Or it is rather normal...

 

Here you go...


...and, congrats on the nice upgrade. Your vintage laptop is from a bygone era before all of the ODMs became lobotomized eunuchs with an insatiable fetish for peddling disposable rubbish.

Older laptops never die, they just go faster.

Newer laptops just die, they never go faster.

Sockets and slots FTW!​

 

Who needs to go faster when you can go faster than a laptop with sockets?

 

Right... until it craps out and you have to toss it into a dumpster because the replacement mobo costs almost as much as the turdbook did when it was new.

 

By the time that'll happen, most people will be dead or it'll be too useless to even look at using for a daily machine

 

Nah, there are plenty of upgraded Clevos that are 4 or 5 years old that are still kicking the teeth out of the latest and greatest soldered trashbooks. The concept of paying a lot for castrated throw-away rubbish is one of the mental illnesses that plagues the world we live in. Nothing needs to be good or be worth a damn as long as it sells well, has RGB lighting and lasts long enough to get past the warranty period. They don't want to build anything that is durable, easy to fix, or upgrade, because they can't sell another round of disposable garbage to the kiddos.

 

All the dead Alienware 17 r4 would like a word with you. 7820hk / 1080 have been dropping like flies.

 

A couple of laptops =/= all of them.

But they aren't? A P870DM can barely handle a 8700K at full bore, VRM or cooling wise, and the even with a 1080 in it. And thats after all the insane mods you'd have to do to get it working. It'll still get thoroughly beaten by BGA'd laptops with 9980HK's and 2080's. That's just the flow of technology. and how it works. Technology changes, for the better or worse, but it gets faster and thinner. There are Macbooks faster than a stock P870DM. Sure, the P870xx line is the king of upgradability, and there is no denying that, but whats the point in having the path to upgrade if it'll get beaten by laptops that are significantly cheaper than it? To replace a GPU that fails? Don't buy a laptop that'll fail within a couple of years then, treat it like a laptop and not some idiot with a chromebook, and maybe you'll see it lasting longer than one.

I don't think I'll say anything else, we're going off topic of the thread and if you feel it necessary to continue to rant, I'd suggest doing it elsewhere. I know you will, so I'll leave it to this

 

The fact that debate can occur around it kind of says it all to begin with. You want to compare it with systems 3 generations it's senior to make the point, which only demonstrates a counterpoint to me.

Some people actually like what they have in terms of usability which is why the next question is if you can keep it relevant to current equal tier hardware. No offense to @Mr. Fox but his mods aren't exactly insane either. Replacing a 980m with a 980 desktop and it's corresponding memory is insane to me lol

Point being, outside of running lines you have no idea if the next machine will fit you like a glove like the current machine. If you like what you have and can upgrade, why not?

I especially love it in business line laptops because of the design aesthetic it becomes a sleeper machines with tons of muscle on the cheap. Especially after selling the previous card at Nvidias inflated pricing on ebay.

People keep asking why bother, obviously it's still being done which means it's worth it to them, the why is there own.

 

I've flashed a Quadro P5000 which I'm pretty darned sure is Pascal ... I did under Mint Linux 18 using the linux specific version of NVflash.......

 

That was a beta vbios not a modded vbios iirc, I'm assuming you are referring to the m6800/m6700 upgrade?

 

Prezactly though I'm sort of unsure what difference that makes ....
