Oh, thats sad.
The store I bought it from and the Silicon Power website stated the same speeds for all the capacities.
Thanks for the clarification.]]> Sun, 08 Sep 2019 07:06:22 +0000 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67677&title=b450m-pro4-nvme-m-2-ssd-speed#67677 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67665&title=b450m-pro4-nvme-m-2-ssd-speed#67665 Author: Ray62

Everything is ok with your SSD. If you want real 3000MB/s write speed, you have to use the 1 TB version.

Silicon Power P34A80:
Silicon Power PCIe M.2 NVMe SSD M.2 1TB Gen3x4 R/W up to 3.400/3.000MB/s
Silicon Power PCIe M.2 NVMe SSD M.2 512GB Gen3x4 R/W up to 3.400/2.300MB/s
Silicon Power PCIe M.2 NVMe SSD M.2 256GB Gen3x4 R/W up to 3.100/1.100MB/s

Geman site, but look at the pictures, it's the P34A80

Tested a few things, the only one that helped was if I turned off the Direct I/O in ATTO, after that I reached ~3000MB/s write speed, but the read speeds gone up to almost 6000MB/s, which is non-sense.
Tried to turn off the RGB, it did nothing in my case, checked the Windows settings regarding write cache, everything was okay by default.]]> Wed, 04 Sep 2019 16:17:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67523&title=b450m-pro4-nvme-m-2-ssd-speed#67523 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67488&title=b450m-pro4-nvme-m-2-ssd-speed#67488 Author: gizmic

atto and crystaldisk is enough to flood cache i know this because i can sometimes get 700MB/s on write seq q32T1 on 970 evo

but i know it goes back to 24XXMB/s when i diable razer synapse + asrock rgb ]]> Tue, 03 Sep 2019 18:47:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67488&title=b450m-pro4-nvme-m-2-ssd-speed#67488 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67485&title=b450m-pro4-nvme-m-2-ssd-speed#67485 Author: Dusee

I know that, but it never exceeds 1000MB/s, like it is fixed to that value.
Review: https://www.tomshardware.com/reviews/silicon-power-p34a80-pcie-gen3x4-m-2-nvme-ssd,6180-2.html
In the sustained sequential test You can see that if the cache is full it throttles to 1000MB/s, but in my case it didn't happened, cause an ATTO or CrystalDiskBenchmark doesn't write that much data.
Is there a setting/trick in Windows which You have to enable to use the write cache, it is not enabled by default?]]> Tue, 03 Sep 2019 17:02:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67485&title=b450m-pro4-nvme-m-2-ssd-speed#67485 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67465&title=b450m-pro4-nvme-m-2-ssd-speed#67465 Author: kschendel

3GB/s write speed would be pretty impressive for any SSD. Who claims these rates? I'm not sure I can hit that with a 970 Pro, which is one of the fastest writing prosumer SSD's available. It may be that the 3 GB/s figure is only valid for very specific conditions, like staying within write cache or something.

Hi

I have a Silicon Power P34A80 PCIe Gen3x4 M.2 NVMe SSD 256GB, this drive should reach around 3200MB/s read, 3000MB/s write sequential.
The read speeds are OK (3200MB/s), but the max write speed is 1000MB/s in my case (tested with ATTO).


My config:
B450M Pro4
Ryzen 5 2600
2x8GB 3200MHz Team Group T-Force Delta RGB
Win 10 Pro 64bit
BIOS 3.50

Every driver is updated to the latest, the SSD installed in the correct slot, in the BIOS the link is set to Gen3.

What can I do to reach higher write speeds?

Thanks!]]> Mon, 02 Sep 2019 15:08:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=12353&PID=67422&title=b450m-pro4-nvme-m-2-ssd-speed#67422
