Hello everyone. I recently bought a MacBook Pro 15" Late 2013 2GHz. I'm running the latest version of Catalina 10.15.7
I swapped the 256GB Apple OEM SSD (Samsung chip based), and replaced it with a Samsung 970 Evo NVMe 500GB along with the gum stick M.2 adapter. I'm noticing 1675 MB Read / 1523 MB Write. It's definitely an upgrade from the stock 820 R / 665 W I was getting before. But the speeds are not up to spec. Is the motherboard for late 2013 PCIE 2.0 ?

Also when running bootcamp along with Windows 10, I installed Samsung Magician, and it also gives me the same read/write speeds. Regardless if I use the Samsung NVMe Driver or not.

Either way, I'm happy with the result, just trying to get the most out of the drive, or as optimized as it can be.

That speed is about right, 2013 model only support 2x4 . Only 2015 15" model can do 3x4, so nothing wrong with your setup
 
Hi
I found this ssd ADATA XPG GAMMIX S11


I have MacBook Pro 2015 - 13”

Gammix wont fit into macbook clearance, it has preinstalled heatsink.

Better go for SX8200 if you want adata. And get short adapter.
 
I have a weird problem with NVMeFix. It installs and loads just fine with Hackintool. I disable SIP while installing and enable again after installing. Both NVMeFix and Lilu kext load fine the first day or 2, even after multiple restarts, but after that they stop loading on around the third day. Any idea why? It's like the permission to load unsigned kexts get revoked.
Catalina 10.15.6.

Did you enable debug boot args ?

or even better, just dont use catalina at all if you aint have to. Lol
 
Yes, when I had to secure the drive it bowed slightly. But I don't follow how that results in kernel panics consistently using the same app. I installed this over two years ago and it's been going fine until recently.

As some of you might remember, I use two (512 and 1TB) Silicon Power on my MacBook Air Early 2015 and MacBook Pro Mid 2014.

I had been having at least one kernel panic a day lately (it did not happen in the first four months) in my Air.

I open the laptop and removed the SSD. When I unscrewed it, I felt like if the SSD was loose inside the Sintech short adapter.
Anyways, because I used the original screw, I thought maybe it was my perception only.

What I did that resolved the problem (it's been running without any panics for about 3 weeks now):

I put Kapton Tape on the board UNDER the SSD. There are some metal points there and maybe there were some capacitive effects between the SSD and the board, which caused the panics.

This is my experience and I hope it helps someone!!
 
Howdy @pimu96! When you start Black Magic, it will cycle over and over automatically until you press the Start button again. Sometimes what's being read and written changes. I notice that one test run will check all boxes and the next run will not, then the following run will check every box again. I don't know why this is, someone else with more knowledge of the program may better serve you.

As for the iMacs, yeah, those are some pretty slow speeds, especially for the HDD. Have you run the benchmark from a fresh restart?
Hi @Shrimply Pibbles,
Thanks for the info! If someday I learn more about how BlackMagic works I'll post it for sure.
About the iMac speeds:
- The iMac with Samsung 860 EVO giving ~400MB/s do you think is slow? I think it's not the best but I do not know what else to do. This mid2011 iMac is the product of replacing an HDD with the SSD and then filling the info directly by hand (I mean selecting the folders and reinstalling the apps one by one, not using any Time Machine copy). I did it that way in order to not to copy the junk of the previous HDD. Any suggestion to improve the performance? (I know it is a SUPERgeneric question because there is need to know more about the machine, but maybe the community has a cooking-book-recipe MO on improving the speeds, which I would be very glad to hear about)
- The iMac with HDD, I know it is amazingly slow. The iMac is from 2017 and it takes about 1.5~2 minutes to start up, in order to open a folder with a reasonable number of files it takes maybe 10 seconds, the preferences app takes a lot to open too, and I could go on and on. Actually, it has been a PC which always took a long time to boot. The last month I decided to take all the information into an external drive, wipe the entire machine out in recovery mode (but not cleaning the HDD with maximum security, I think I cleaned with the lowest value -which I think it is like putting all 0s-, I do not know if it matters or not), install Catalina using a USB boot and then put the info again folder by folder (as you can see I am a bit hypocondriac when cleaning stuff and I just go raw selecting the folders by hand). However it did not improve much more, actually I think it improved NOTHING and the placebo effect of me cleaning stuff is kicking in. I am planning to reformat the HDD again with the maximum number of random number overwrites (7) and installing Catalina from scratch. I hope to get better performance but I am not very confident to get any results. Any suggestion? Do you think that maybe the disk had a manufacturing error and never went well, or the problem can come from another thing? If I am too desperate I will try to change the HDD with another SSD, however I am trying to avoid this because the Apple engineer fams thought it would be nice to replace the magnets of the plastic cover with some adhesive much more difficult to remove.

Sorry for the long post, today I woke up feeling like a writer even though English is not my mother tongue and I did not want to kill the roll ;)

Thanks again!

Hi @macpro_mid2014, I'm glad you solved it! When you say you put Kapton tape on the board, you mean in the PC board, or in the SSD? The first time I knew about Kapton tape was in this forum and I have never used it. I am planning to buy a roll because I remember reading somewhere to put Kapton tape on the sintech adapter (but not directly on the metal pins). Is it correct to put it there? Completely newbie here
Thanks,

Will the processor heat up faster if we use the 970 Evo? (Early 2015 13 inch MBP)

I've recently installed the samsung 970 Evo 1TB into my Early 2015 13 inch MBP. (macOS 10.15.7)
Yes it's generating more heat then the stock apple ssd & it's draining my battery faster.

Reading through this topic, I've devided to switch it for the Sabrent Rocket 1TB.

I live in Turkey. There's no way I won't get Sabrent here. Do you think I should buy ADATA XPG SX8200 PRO?

Catalina 10.15.6.

Same problem here, it may be related to deep sleep (closing the lid at <5% battery power). Generally a restart fixes it.

I've also noticed I can't re-enable SIP and have NVMeFix work reliably without having the symptoms you've mentioned.
 
Seems like latest NVME fix working great

Idling on 0.4x W
Memory on 0.01W

A1708 - 2017
DST5100 1TB

How is the battery doing? Does the processor heat up quicker?

Hi all,

I upgraded my MBP 15" Mid-2015 to a Samsung Evo Plus 1TB today. No snags, apart from me realizing I needed a pentalobe screwdriver *after* I started and already wiped the original Apple SSD. :rolleyes:

I upgraded Sierra to High Sierra (clean install) and then to Mojave (clean install.) With Mojave I got bootrom 199.0.0.0.0.

My adapter is the Sintech short one, straight from Sintech. No exposed pcb traces so no need for Kapton tape. I was going to see if Samsung Magician would boot on a MacBook but since everything went swimmingly, I've put that off.

If there's anything someone wants to know, just ask.

Many thanks to you all. I already fell into the GPU Upgrade iMac 2009-2011 rabbit hole...

Cheers!

Is there a guide to installing NVMEfix? I did not come across this at the beginning of the topic.
Thats's because this thing only known later,

Installation is pretty simple and straight forward. And it will be better if you are on mojave

1. Boot to recovery.
2. Open Terminal, and type this two commands
3. csrutil disable
4. nvram boot-args="0x144"
5. Boot back to system
6. Download LiLu.kext, NVMeFix.kext and Hackintools all from GitHub
7. Use Hackintools to install both kext to S/L/E and rebuild kext cache.
8. Reboot, at least two times

You are done. Shall you have problem or crash when reboot, it means your ssd doesnt support APST and play funny when it enabled. Simply boot to safe mode and remove the kext.

Thank you.
Which SSD do you think I should choose? 970 EVO or SX8200 PRO?

As far as i can remember, SX8200 pro doesnt really get along with NVMeFix, it doesnt crash, but it doesnt improve either. Lol

970 is surprisingly a good idler after the fix. Although it's kinda pricey (especially in my country) but if you manage to snatch a good deal, then go for it.

I have today install both kext ( Lilu & NVMeFix ) with Hackintool but on my Mojave System ( its current up to date ) both kext will only load if I installed them in L/E in S/L/E there will not load on booting the system !!

I can confirm that NVMeFix work properly on my MBP11.1 with EVO970 1TB and the IDLE power reduce from 2,5 to 0,4-0,5 W.

Now im happy cause that was the last step after im successfully patch the BootRom with CH341A Mini Programmer and the J6100 adapter - thanks for the great manual here !!

Does this happen to anyone using the 970 EVO?
