Did Evga also changed the ram in the FTW cards, I was aware some superclocked models already came with micron chips, but was hopping that the top tier card will remain unmodified in that respect. Any official word on this?

The 1070 uses GDDR5. The 1070 FTW uses samsung memory. Only the 1080 uses GDDR5x which is Micron.

Yes I know, but some others AIB partners already switch the supplier in the 1070 memory from Samsung to Micron (cof MSI fiasco cof), and I was surprised when I read a costumer review claiming that his new 1070FTW card also came with Micron chips.
 
 

Worthy to note: this card came with Micron GDDR5 memory chips. There are two types of memory on these cards, Micron and Samsung. Reports indicate that samsung memory can overclock much higher than the micron memory. Some users are investigating whether the Micron memory is of lesser quality, or if the video card's bios does not have an optimized power delivery curve for the memory modules. There are different versions of 1070 bios depending on the memory module installed. Some users have tried various micron bios' of other brands with mixed results. The important thing to note is there does seem to be an effect on the overclock ability and different card bioses.

I have to admit that by paying a bit extra for EVGA's most powerful version of this card, I expected to receive the best of the best, which would mean not having Micron memory. Hopefully BIOS updates are available in the future that allow for the Micron memory to reach clocks similar to the Samsung memory.

line them up by most recent review.
 
I will try to upload a gpuz validation of this later on.

My first 1070 ftw card had Samsung memory and now my 2nd has Micron memory. First card had annoying whine coming from the fans.. so does this second one also.. 

Thanks for your input. So it's confirmed that some (if not all) of the latest batches of 1070 cards will come with micron ram. sucks

Micron is top tier ram like Samsung. What's the issue?

Noticeable lower oc potential, in a FTW card 
but also after this: I'm kind of skeptical. 
 

MSI GeForce GTX 1070 Quality Problem In China, 100% RMA Return Rate

MSI GeForce GTX 1070 Duke
The real reason for all this defective production is unknown, but it is logical to think its production problem, because all affected graphics cards were manufactured at the factory in China, not Taiwan. The production factory in Taiwan supplied graphics cards to other markets (Europe, USA, etc.). Next to the factory, another reason could be that these graphics cards had used Micron memory chips (non-affected models are equipped with Samsung chips), which might lead to temperature problems that would be causing these artifacts by excess heat. Although none of the two hypotheses have been confirmed by the company.

1.  Micron makes very good memory.  Micron rivals Samsung and TSMC for the top position in the world.
 
2.  You quoted someone claiming 100% RMA rate without providing a source.  Claiming a 100% RMA rate is laughable -- impossible -- which makes everything else related to that claim quite unbelievable.  Do you have any proof from any reputable source which proves that this Micron memory on this card is any worse than this card is with Samsung's memory?  I mean proof.  Not just a few people claiming their card didn't overclock well and therefore Micron sucks.  I am not talking about someone's Amazon review either.  I mean reputable from a well-known source by someone with a degree in electronics and a large enough sample size to prove something is statistically likely to happen and is more than a random chance of a small sample size.

1. Yes, I'm aware of that
 
2. You're right. This was a rumor/news spread in various forums from a translated letter that appears to be from MSI china. I admit that the claim is suspicious but I can't affirm that is not true. You can google it and make your own conclusions.
As for your claims of proof, I mainly do my purchase by reading a lot of opinions from reviewers and costumers, like the 99% of the consumers. Hardly the actual reviewers have a degree in electronics, or the time to do a study of the scale you are referring. 
 
Anyway, Jyrtzy already answer my question.

An other DP cable seems to be OK. tracking...
Thanks for advice.

I had one 1070FTW with Micron VRAM. It often flash garbage on my screen.
After RMA... i got a new one with Micron VRAM again. And still flash garbage...
I recorded a video for the symptom.
But my old VGA card -MSI GTX970 Golden didn't have this problem..
 
I don't know is it Micron VRAM problem..

Yes...sometimes flickering still be happened, even changed the cable.
But I think the new cable has some improved, the flickering less than old cable.
 
I will borrow some cables to check again..

The point is that it's NOT a cable issue, it's a driver issue. There are hundreds of people reporting flickering with the 1070, 1080 and Titan XP.
 
I thought the same as you at first. I changed cables and three different monitors (RMA). I also changed card from 1080 FE to 1080 FTW - the issue persists, though lessened with each driver release.

Sounds like this has wandered off on another red herring where once again Micron memory is being blamed for something which is not a Micron memory problem.

The "Micron" problem is not the Micron Ram itself but, I believe, a bug in the micron version of the bios that increases the clock speed of the Ram from a low voltage state (below .800v) faster than the VRMs can be cranked up to provide enough voltage for the memory to support the high clock speed. An overclock from low voltage states will start giving checkerboard artifacts somewhere in the +400 to +500 range. 
 
If the voltage is already set high when you increase the slider and hit the apply button. running Kboost or locking rge voltage in afterburner, the memory will clock to +600 or better with no artifacts, of course the exact levels will depend on the individual card.
 
The Samsung memory either copes with the few milliseconds of voltage starvation better or the different bios version increases the voltage faster to support the memory at the high clock speeds.

Sounds like a crap shoot. I've been wanting to upgrade to a 1070 and was going to pull the trigger shortly. What's the verdict? Should I wait a few more weeks and see what happens or has most of the issues calmed down since op wrote this? 

my 1070 FTW2 has Micron. Both of them do.

My 1070 SC2 has Micron VRAM, clocks to 9008 mhz too. I used the slider to manually set the vram to +500, then used the manual curve for the core, 1.062v @ +125 mhz = 2113 mhz. A little over 500 points shy of a 21000 graphics score in Firestrike.
