Re: HELP! Booting from SM951 AHCI via PCIe Adapter on Z87M Extreme4
Update - So I made a Windows 10 boot UEFI USB through magicISO and Rufus following RAMCity's instructions. I now need to know if there any other things I need to set up in the BIOS to get this SSD to work and boot into windows 10. At this moment I am still waiting for the SM951 to arrive, I will give an update later when I get it attached and set up (fingers crossed it works fine first time!)
Also, do you reckon I will get full speed with this drive installed,as my motherboard has another PCIe 3 x16 slot available next to GPU. The sm951 can handle up to 4x lanes of pcie 3 as its max to get those 2000MB/s read and 600MB/s wrights. will this mean my GTX760 thats in the first x16 slot will have its bandwidth halfed down to x8 speeds and run slower?
my cpu is 4670K.
thanks.Comment

I'll let someone who games chime in on that. Honestly, I don't game at all so I wouldn't have the foggiest idea.Originally posted by K4MR4N View Post#1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.

Re: HELP! Booting from SM951 AHCI via PCIe Adapter on Z87M Extreme4
lol dont worry i just did some digging and found really good article on TechPowerUp on PCIe scaling, difference between PCIe 3 x8 and x16 is extremely small and most of the time no difference in performance!Originally posted by - wardog - View Post
anyway GPU's are a discussion for another time and another thread,
I just can't wait to get the samsung SSD through the post, first move to an SSD and hopefully everything goes well! lol so many stories of people saying the same thing, "once you go SSD u never go back"
well i'm going from HDD straight to PCIe SSD so difference should be huuuuge!
I just hope windows 10 and basic programs will be enough for the 128GB drive after its formattedComment

Re: HELP! Booting from SM951 AHCI via PCIe Adapter on Z87M Extreme4
When I fitted my sm951 256GB onto a pcie to m2 adaptor I thought if I put it in Pcie 3 x8 next to the graphics card slot performance would be hit on my Gtx 970 G1 so I put it in pcie2 x4 on my Asus Maximus 7hero but like you found out performance between pcie 3 & 2 is marginal but I left it in pcie 2 x4 slot quite happy with the slightly lower read & write speeds...Comment

You monitoring temps on the SM951? I heard it gets really hot when in use, I have open area in my case which is phanteks enthoo evolv so the front 200mm fan is blowing through the system and hopefully right on top of my card also the fans on the GPU may affect temps don't know yet.Comment

Well my SM951 256GB Idles around 29c and when I ran Anvils 32GB benchmark it shot upto 54c very quickly...

Re: HELP! Booting from SM951 AHCI via PCIe Adapter on Z87M Extreme4
I asked Asrock if the NVMe drives work with the new BIOS update beacuse I didn't know 100% if the NVMe capability would be available through just a firmware upgrade as I initially thought it was a hardware level specification on the motherboard that allows use of NVMe drives. And they replied saying they have tested with the L2.10A BIOS the samsung sm951 256GB NVMe drive with my exact motherboard and success! it works. They did say however that If I am installing windows on it as boot drive then I have to install it in GPT mode, this I have done following RAMCity's guidance on installing the drive as a boot device.
I ordered the AHCI model of the 128GB prior to all this findings and now I will try to cancel the order and get the NVMe OEM version as it seems to be by spec, have much faster Random IOPS , 4KB Random Read is at 300K for the NVMe and 90K for the AHCI, also 4KB Random Write is at 83K for NVMe and 70K for AHCI.
Its a no brainer reallyComment

Yea, GPT is a requirement. Either AHCI or NVMe.

Re: HELP! Booting from SM951 AHCI via PCIe Adapter on Z87M Extreme4
Okay so having some issues getting the SM951 NVMe to boot ! 😫
I have followed RAM City video on how to install it on Windows, however once I complete the installation set up going through the interface , it restarts in the end and then just doesn't boot from sm951 as if it can't see it anywhere , but when I go through the setup I see it as 119GB space to install Windows 10 on , I click next and then it goes through the process ..
But when it restarts it just boots to setup again from UEFI USB that's plugged in.Comment

Continue ...
And when I go to my BIOS and system browser tool I can see that the PCI slot is occupied with the Lycom-DT120 adapter I installed with the sm951 on it but all the BIOS says is Mass Storage Controller, is this an issue with the motherboard not being compatible with the SSD? Because Asrock support emailed me and confirmed that it works with the BIOS that I flashed.
