View Full Version : M.2 NVME on Maximus X Hero

Hello experts,

I am looking to fully utilize my M.2 NVMe on my Maximus X Hero. Currently, I have a 960 EVO 500GB which is slotted in the M.2_1 slot (with heatsink) and the max I get before setting everything to gen3 PCIe is 2176 MB Read (can't remember write), and after enabling everything in "advanced options" to Gen3, and explicitly stating for the M.2_1 slot to use PCIe from Auto, I am getting a mere 3000 Read / 1600 Write (using CrystalDisk Mark 6)

Am I doing anything wrong? What other settings should I change? I must mention that I am running XMP profiles and am unsure if anything was changed by that.

Only the M.2_2 slot has option to choose x4 mode from x2, should my card be here instead?

I would greatly appreciate your help.

HI SherardG,

What's the capacity of your 960 EVO?
The 250GB max out at 3200/1500MB/s, while the 500GB at 3200/1800MB/s. and the 1TB at 3200/1900MB/s.

Are you comparing to Raid 0 setups?

How good is the airflow, even with a heatsink on the M.2 it can throttle, especially when you keep running benchmarks.

After focusing on my CPU speeds, I had to revert back to default BIOS settings. I re-enabled XMP, but did not set anything else. (I forgot about the settings you mentioned.)

So you made me curious. I just ran Samsung Magician, and it says performance results 3137 / 2010. It also says the interface is PCIe Gen. 3x4. Also noteworthy was a firmware update applied today, after just updating when new last week.

Did you peel the backing off of the thermal tape that was pre-installed on the heatsink? I was surprised to learn that the blue tape was indeed thermal tape. I removed the label from my SSD and the backing from the blue tape and installed.

Edit* I have a pro, but hope this is helpful. Perhaps mine is under performing as a pro since I'm not sure what the performance should be.

Hello MasterC,
My EVO has 500GB on it. I don't get those figures running Samsung Magician; I read on a thread some threads here that it doesn't report the correct figures, in fact, I am only able to get the 3000mb+ figures from CrystalDisk; I pretty much stopped doing benches since they eat up the lifespan of my SSD.

No, I am not comparing to a RAID0 set up; and I have no plans of running RAID as well. The airflow has a lot of negative air pressure on it. On idle, sensors report them as 37C. Under load after 2 hours of gaming, I get 51C max. My case has a lot of negative airflow which I am trying to turn into positive a/f. I'm currently running 3x120mm fans as intake at full RPM, I have 1 140mm exhaust fan and 2 140mm push-exhaust fans for my radiator. They run on a curve and at idle runs at 39% speed (700rpm).

I might try updating my firmware as well. I did peel off the adhesive protector for the themal tape on the heatsink. What I did not do however, was peel off the label on my SSD. Thanks for your inputs; firmware might have resolved the magician issues, since a lot of people running a 960PRO get numbers which aren't far off from mine using the bundled software, but are blazing fast and hit their rated speed with CrystalDisk.

Figures seem fairly ballpark to me. Don't forget the max theoretical speed is exactly that, and you're close to it. Try updating the firmware as you say.

Hello Silent Scone, everyone,

Thanks for all your feedback. I've done one more bench after upgrading firmware and results stay more or less the same, though the results in Samsung Magician are worse of from what I've got. Since I really have no complaints (was just trying to get my money's worth!) I've decided against running any more tests to keep my TBW's to actual usage rather than from bench marking.

Just one more thing; should I also remove the label on the stick itself and directly stick the thermal pad to the stick? I just removed the blue thermal pad leaflet.

Leave the sticker on, you would need it in case of RMA, it also has a thin copper layer as heatsink

Just saw your reply now, but thanks! I did think that it would void warranty but wasn't sure.

There is another label on the the other side of the SSD which I think has the info related to RMA.

I'm undecided if the copper label style heatsink residing between the thermal tape for the MB heatsink and ICs would be a benefit, since there is another layer of paper or some other material on top of it. It appears to me to that the copper label heatsink is best used in standalone applications only. But, I'm no expert on these matters!

I am sure removing the sticker will improve contact between the thermal pad and chips by a small amount, whether it's a measurable amount can only be determined by testing with and without removing it.
You would see the biggest temperature difference with active cooling

I am actually thinking on how to source a mini fan and mount it on the middle area (M.2_1 slot) haha. At what temps do these chips start to throttle anyways?

I am using a Noctua 40mm pwn fan and set it on top of my Video card, reduced temps 5 to 10 degrees at idle, I am thinking of installing the fan mount to the middle motherboard mounting screw just to the right of the M.2 slot except my Corsair case standoff at that location sticks through the motherboard mounting hole and no screw so I would have to remove everything to change the standoff, system just runs to good to be messing with it:)

One Question. Im having a Samsung 970 pro and in the Samsung Magician performance benchmark im reaching only 290k IOPS Read and 263K IOPS Wirte see attachment. My Temprature for the 970 Pro is around 47 degrees celsius on the m.2 heatsink slot of the asus rog maximus x hero motherboard during the performance test. Also i have activated the PCIE Gen 3x4 support. I dont know why i cant hit the advertised 370k IOPS READ and 500k IOPS Write . I thought it could be BIOS settings.

Anyone have an adivce?

Anyone have an adivce?Have you installed the latest drivers NVMe SAMSUNG v3.0.0.1802 ?

The performance stats for your device are as good if not better than those for my 960 Pro. It's actually nice to see that the 970EVO has improved and is better priced. As far as the "Advertised" R/W iops, IIRC those numbers are based on Sequential vs. Random. The Magician benchmark R/W IOPS is testing Random which is slower than Sequential but, also more representative of everyday use cases. Using the sequential test numbers in marketing "looks" better as it will always be a larger number than random.

Here's my 970 Pro 1tb results, IOPS is under what the reviews suggested, latest firmware/Samsung drivers. Installed in #2 slot and x4 mode enabled.

I have the latest Samsung Driver installed. So the 370k/500k random read/write IOPS is fake advertisement and 300k is the truth? Or is there some BIOS setting im still missing?
