I almost would bet on it , had the same years ago where sata3 was new on desktop mainboard , used the wrong cable with similar effect

If my reseller had played along i would have send it back but because I have it 4 weeks already they only offered me to send it back to EVGA to check if something is Broken ....... i tried to tell them there is nothing Brocken .... just a 2017 Notebook with no sata3 Support

By the way i got in contact with EVGA Support it’s the same here , they don’t try to fix this only standard replays

„We can only guarantee for the installed components“ ..... this made me laugh out laud .... even the installed hdd is Sata 2 only ,

„Beta Bios works with some SSDs, but we can not guarantee for all SSDs“ ...... then why don’t they tell which ssd are working ?

I wish i would know someone with the necessary knowledge and tools who could Test the ssd cable .. i would pay for it

Hi everyone,

I found a solution for your problems. So I had the same issue as you all. Tried this with both my samsung SSDs and got only sata 2 speeds. But I had a kingston UV400 ssd lying around so I just tried it just got kicks and it totally worked... got 540 MB/s read speed and 368 write for sequential read/write. Just thought this might help all of you. Of course this was after I flashed the beta bios and set it to gen 3

I have a feeling that it particularly does not work for samsung ssds for some odd reason. Maybe a few others too but I'm sure that if it works for kingston then it might work for others as well... maybe it has something to do with the way the sata controller interacts with specific ssd sroms? 
 

Thanks good to know but why can’t evga do something about this ..... this would be easy for them to test some ssd and tell us the result but no they don’t do anything their customer Support is really bad

The thing is this model is a „little“ old , what happens if I buy a new uv 500?

Tested and don’t work or have problems with the beta bios ,

I have a feeling that they probably knew about it. That's maybe why the Sata gen3 was locked in the first place. Also, I guess UV500 might work? You can always get one and return it if it doesn't. Maybe the hardware/firmware that kingston use might be compatible with this laptop or maybe samsung has some sort of proprietary way of interacting with sata controllers? Anyway, at least we know some SSDs would work as expected and that EVGA hasn't blundered completely. Apart from this small hiccup, I really like this laptop. Wish they had a bios option to turn off the gsync monitor setting completely so that even the iGPU could work. If this was available then we could've made a hackintosh out of this machine as well.

Anyway it’s good to know that some might work ..... i guess your ssd + Beta bios is stable , when I run my 860evo + beta bios the notebook behaves a bit wonky , sometimes it loses the ssd within windows sometimes is not even showing up within the bios with the beta

368 write is not that good, not much more than we are getting now with SATA II.  The MX500, for example, benchmarks at 510.

Well, I just checked and realised that I'm not on the beta. I unlocked the 1.06 firmware by following the dude on page 1 of this thread. So far it hasn't failed to detect the ssd. It did a few times on the beta though on the samsung. Also, if it does even after you try the unlock, maybe try enabling the hotplug setting so you can detect it from windows whenever.

Just did another test and yeah its 541 read and 375 write. Guess it's a hdd limitation because I had similar numbers with this on my desktop too. But it's good enough for me, i prefer the faster read speeds vs write

Yup, it's not bad.  Definitely way ahead of a platter drive!  :)

So for now we can say don’t use the beta bios and it would be better to use the hack on 1.06 (at our own risk )

@shriramhr , could you tell us what size your ssd is ? Because if it is the small 120gig the write speed could be max , Kingston says 550/350

Edit hm ,
Uv400 Controller Marvell 88SS1074
Uv500 Controller Marvell 88SS1074

maybe it’s a controller thing , just found this Site with more ssd who used this Controller , damn no links in this forum i forgot

Anyway a mx300 should have the same controller maybe i try this one
