Topic: Very first tests P104-100: 39 Mh/s Ethash; 470 sol/s ZEC - Nice GPU! - page 8. (Read 9368 times)

Hey,

Some more historic info.

This card did 28-29Mh when it first got built a few months ago, which was completely stock.

When we were first testing it with nvidia, i did a small and simple tweak and i got it up to 40Mh+.

It is now selling with that small modification for around 500USD per card, that is if you can find/get it.

That initial 40Mh we got was indeed as i said with custom timings, also knowing that the prototype had only 4GB GDDR5X memory.

For your reference, the ones being built/sold have 8GB GDDR5X memory. (not that it will make such a huge difference)


Cheers


Edit: it is now selling for over 900USD..

Here's the original Vbios that was on the prototype when i first recieved it months ago.

I'm however not going to share the modified one that gets you up to 40+Mh, not that it would matter that much as it's out there anyway..
Still, i honor my NDA's.

Greetings

My Palit P104-100 cards look exactly like Palit GeForce GTX 1070 Dual without display outputs.

neoscrypt hashrate is ~1.2 MH/s with alexis78 ccminer.

can anyone with that card please run ccminer and check neoscrypt performance please:) ? any coin .. feather gobyte etc...

I meant to extract the BIOS file and upload it somewhere.

For VBIOS using GPU-Z, you could check it in 3rd image of my 1st post. I made it for a while already.

Or you could check it here: https://imgur.com/a/ga8Zq

Please dump the VBIOS using GPU-Z and post it here.

If you want to see the its design or its cooling or sth like that, I could take a picture next week when I come to farm.

But the official GPU has not released yet so basically I need to ask my distributor about posting GPU image.
He agreed for spreading the words about performance I think it's the way the make price. But honestly to say, its cooling is not good as I expect.

 That is NOT a 1080, which has 2560 cores - it's a 1070 with 1920 cores but GDDR5X memory instead of GDDR5 memory.

 The early RUMOURS were 1080 with GDDR5 but that turned out to not be the case.

 Still doesn't explain how it manages the announced high ETH hashrates claimed for it.


 The 4GB vs the 8GB on a regular 1070 isn't a factor, and probably won't be before ETH goes Proof of Stake.

This card is basically GTX 1080 with DDR5 memory not DDR5X.
Therefore it performs very good with ETH algo but not so impressive with Equihash algo.

If it is under 500$, it is very good buy currently.

FYI:

I've contacted a few manufacturers from Alibaba, most of my queries for P104-100 take very long to get answered and not even in a good manner. Anyway here are few price points they threw at me: $425 $478 $485 and from another manufacturer $880 $760. They also have prebuilt 8xP104 rig for about $4680~4880, some may accept small order if you contact them, i recommend using Whatsapp. They are available to pre-order only, available April. Most of the parts and the GPU itself are made by unknown or lesser known brands: newmagic, Manli, Inno3d, Jegy, Onda.... From which I only trust Manli and Inno3d. In order to order they mostly will talk you to add their Whatsapp number (or Skype) and pay outside Ali via T/T or some sort. Very risky indeed. Warranty will be 3 months for most if not all brands. After-sale support is horrible as I read the feedbacks from previous buyers and around the web; any broken card will need to be sent back costing lots of $$ even if you're lucky enough to get a reply from them. If you willing to deal with them I can help you find out legit manufacturers but again warranty isn't good and you buy with your own risk.

P/S: Luckily I found a distributor who travels back and forth from US to Asia to bring here some goodness, batches of P104-100 from Inno3d, MSI and Zotac available end of Jan and end of Feb. Yata! However I can't share his contact information without his permission. So sorry the community.
