g751jy Pcie ssd questions

[Lubert85]

Hello!

I have preordered the g751jy in norway, but there is still limited information on the actual product.
The only information on the ssd is that it is 256gb m.2 disk. Is this the pcie version. And does all g751jy ships with a pcie ssd?
And the information i got on the store is that it has only 16gb ram. And i cant find in any other country a g751jy with 16gb.

So im a little frustrated with the lack of information i can find out about it.

Hi iwantspeed,
The G751JY only works with PCIe Gen 2 & Gen 3 (AHCI) M.2 SSDs' not the newer PCIe Gen 3 (NVMe) M.2 SSDs'.
The best available PCIe Gen 3 (AHCI) M.2 SSD for booting the G751JY is the 512GB/256GB OEM Samsung SM951
PCIe Gen 3 (AHCI) M.2 SSD. Unfortunately, the retail Samsung 950 Pro SSD is PCIe Gen 3 (NVMe) M.2 SSD and
PCIe Gen 3 NVMe M.2 SSDs' are unsupported by the latest G751JY AS211 BIOS.

I need to replace the drives in my g751jy i have already upgraded to windows 10 without making a recovery disc with backtracker am i boned?

I followed the procedures described here in the first post and in the winyl's post (starting from a backup of the original BIOS, I deleted Mtftpd6d, added NvmeExpressDxE and flashed with afuwinx64) and now the SM951 512gb NVME (MZVPV512HDGL) in my G751JY boots without any problem in few seconds! 😉

It would be nice if ASUS provided owners of the G751JY notebooks a BIOS update which supports booting to PCIe 3.0 NVMe M.2 SSD. This is the one
thing that dead ends owners of the G751JY from upgrading to the newer, larger capacity, faster PCIe 3.0 NVMe M.2 SSDs'. It would also be helpful
if in the new BIOS update ASUS fixed the low PCIe 3.0 AHCI M.2 SSD sequential READ of 1600 MB/s (not even close to rated 2150 MB/s) most
G751JYs' can only get.

Hi guys!!!

My first post in the Forum! :cool:

I purchased a used G751JY-T7159H in Germany, it is the model with 4720HQ, 256GB SSD, 16GB RAM, GTX 980M 4GB.

But in the deal the old owner wanted to delete all his data, and he deleted all the partitions too. So I lost the hidden 15 GB backup partition and had to install from zero. I'm using the latest BIOS 211, and I couldn't boot from USB to install Windows 10 in a UEFI. It doesn't show on the options, only the SSD, but without system, it boots straight to the BIOS every time.

So I had to change do legacy and install in the old BIOS way (I could choose all the options (USB, Bluray, etc) which are unavailable in UEFI mode). But the boot time takes 5 times more... I want the UEFI back!

Can anyone help me cloning the 256 GB SDD and uploading in my Cloud Storage?

My plan is to clone back someones partitions scheme, with GPT mode, change the BIOS, than boot in UEFI and then perform a clean restore. Sounds good?

If anyone has a better idea I would love to hear.

Thank you very much!

Alex

Hi again guys!

I have managed to install the right way and now I got the UEFI boot again! No need for this crazy and large operation! Lol!

Hello guys. I'm not entirely sure if this is the right place to post my questions but long story short I want to swap out my HDD for an SSD but I don't know if it's compatible or not. If you're interested here's the link to my post * * *https://rog.asus.com/forum/showthread.php?88800-G751JY-T7132H-Questions-about-swapping-HDD-for-an-SS... *I would highly appreciate it if you could check it out and give me your feedback. I'd prefer you replying on my post directly but here is good as well. Thank you for your time.

I've been looking for a Samsung SM951 512GB AHCI SSD, but they are getting difficult to locate and the prices are getting out of hand. Are there any other options that might work? I would REALLY like a 1TB SSD, but would be happy just to find a good 512GB SSD at this point. This is to replace the 256GB SSD in the left-drive of a G751JY.

Thank you,

J

Out of curiosity I recently browsed a few retailers to look at the prices for the 512GB OEM Samsung SM951 PCIe AHCI M.2 SSD and like you state, they're getting harder to find, and the few that are for sale are now over $700 US which is nearly double what I paid for mine Dec. 31, 2015.
Luckily I bought it when I did and upgraded my G751JYs original 256GB XP941 to the faster, larger capacity 512GB SM951PCIe AHCI M.2 SSD for only $365 US on Amazon US website via Platinum Micro. 7-8 months ago they were selling for around $329 US. What a difference a year makes, now Samsung is only producing the latest PCIe NVMe M.2 SSDs for OEMs & Retail market & no longer producing M.2 AHCI SSDs for OEMs
(PCIe AHCI M.2 SSDs are end of life - legacy hardware, no SSD manufacturers produce them any longer).
I found only 1 512GB OEM Samsung SM951 PCIe AHCI M.2 SSD on amazon.com US currently selling for $711 US (plus $4.60 shipping US only). The seller is Electronics World & they list only 1 in stock. Our G751JYs only support two OEM Samsung PCIe AHCI M.2 SSDs, the gen 2 OEM Samsung XP941(supported by all ASUS G751JY BIOS AS202 - AS211) & the gen 3 OEM Samsung SM951 (AHCI version only & provided you have ASUS G751JY BIOS AS206-AS211) as you already know. No other PCIe M.2 SSD brand or models are supported with our G751JY notebooks. If you're not planning on upgrading to a newer model, expensive, high end gaming/mobile desktop replacement notebook for another 2 years or longer and don't mind spending the $711 US, I'd go ahead and buy it if I were you. In a few more months they'll probably no longer be available for sale anywhere. Samsung will not be producing them for OEMs ever again. Our only other option is to bite the big one, spend thousands and upgrade to a brand new notebook that uses the upgradable PCIe NVMe M.2 SSDs. Then we can buy the newest, fastest, larger capacity, retail PCIe NVMe M.2 SSDs like the Samsung 960 Pro NVMe M.2 SSD 512GB $339 US/ 1TB $629 /2TB $1299 US or cheaper Samsung 960 Evo NVMe M.2 SSD or the higher priced, slower performing OCZ (Toshiba) RD400 NVMe M.2 SSD 512GB $279.99 / 1TB $704.99 on amazon.
It's all about supply & demand and since we're stuck w/ only 2 OEM Samsung PCIe AHCI M.2 SSDs supported by our G751JYs that are no longer in production we're screwed! This is why I was hoping ASUS would provide owners of G751JY notebooks one last BIOS update w/ support for M.2 NVMe SSDs. I'm not sure if M.2 NVMe is supported by our G751JYs legacy Intel Broadwell CPUs & our legacy Intel HM87 express chipset on our mainboards, which is probably why ASUS hasn't provided owners of the G751JY notebooks a BIOS supporting M.2 NVMe SSDs? Lack of M.2 NVMe SSD support is one of the few things about the awesome ASUS ROG G751JY notebooks other than the drive bay 2 SATA 2 adapter that is too bad for us.

Hi Jon G,

Go check here : Win-Raid Forum

Check in that post the "Clover-EFI Bootloader Method" too. That one doesn't require flashing bios.

Just found this post too : G751JY-NVME-Support-950PRO

I asked @Linux86 to share the bios with me. If it's really working will be able to use SM951 NVMe and SM961 NVMe (Will have to find out if this model can be used at full speed) . Will link on this post if i got the bios.

SM951 (512GB) : Max sequential (MB/s) Read 2150 - Write 1500
SM961 (512GB) : Max sequential (MB/s) Read 3200 - Write 1700

Cheers.

not sure if anyone still in this topic, but i managed to install MZVPV256HDGL in my Asus G751JT. Followed the Win Raid method.

Reading 1700 MBPS / Writing 1300 MBPS.

Pretty interesting mod.
