NUC8i7BEH上三星970 EVO 250 G的PCIE仅分配了2个通道

我遇到与NUC7i7DNKE上三星970 Pro的此线程性能问题相同的问题
Bios显示970 EVO PCIE NVMe,仅分配了2个通道。读取性能为1702,这是该驱动器的一半。
我有最新的英特尔和三星驱动程序。
是否会针对此问题进行BIOS更新?
谢谢!

I have the same issue as had on this thread Performance problem with Samsung 970 Pro on NUC7i7DNKE

Bios shows 970 EVO PCIE NVMe with only 2 lanes assigned vs 4. Read performance is 1702 which is half specified for this drive.

I have the latest Intel and Samsung drivers. Is there going to be a bios update for this issue?

Thanks!

当您在存储控制器>标准NVM Express控制器>详细信息> pcie当前链接速度和pcie当前链接宽度下签入设备管理器时。
你能截取显示windows中两个值的截图吗?

When you check in device manager under the Storage Controllers > Standard NVM Express controller > Details > pcie current link speed, and pcie current link width.
 
Can you take a screenshot that shows the two values within windows?

我正在使用当前的三星驱动程序,三星存储控制器的设备管理器显示链接速度3和链接宽度4。

I'm using the current Samsung driver, device manager for Samsung storage controller shows link speed 3 and link width 4.

今天早上我跑了Crystal磁盘标记(CDM)来比较原来的三星魔术师结果和CDM结果都很棒!
所以我重新考虑了三星魔术师的结果,他们也是规格,这是他们比较的方式: 
读写
三星规格3500max 1500
CDM 3325 1539
魔术师3282 1535
所以我回到了BIOS,现在它正在使用x4速度8GT / s。
这就是我认为发生的事情。
我在NUC上安装了Windows 10,带有新的驱动器和内存。
此时正在使用Windows NVMe控制器。
然后我下载并运行了三星魔术师基准测试。
第二天早上,我找到并安装了三星NVMe控制器。
我没有重新运行三星魔术师。
在我安装新驱动程序后的第几天,我第一次进入BIOS探索。
我想我取消选中M2盒子以查看会发生什么变化,看看我是否可以选择4个PCIe通道而不是显示的2个,
我意识到它只是一个启用M2复选框,然后我再次重新检查它并退出BIOS而不保存。
我认为这是可能的,因为我在BIOS中的行为,即使我没有保存任何更改,它在重新启动时从2到4通道PCIe重新配置。
你觉得怎么样?
对不起任何混乱,希望我没有对这个模型NUC施加任何阴影,我喜欢它!

This morning I ran Crystal disk mark (CDM) to compare to the original Samsung magician results and the CDM results were great!
So I reran the Samsung magician results and they were to spec also, here's how they compare:
                              Read          Write
Samsung spec     3500max     1500
CDM                     3325           1539
Magician              3282            1535
 
So I went back into the bios and now it's showing using x4 speed 8GT/s.
 
Here's what I think happened. I installed Windows 10 on the NUC with new drive and memory. At this time the Windows NVMe controller was being used. Then I downloaded and ran the Samsung magician benchmark.
The next morning I found and installed the Samsung NVMe controller. I did not rerun Samsung magician.
The first time I went into the bios to poke around was days after the new driver was installed. I think I unchecked the M2 box to see what would change, to see if I could choose 4 PCIe lanes vs the 2 shown,
and I realized it was just an enable M2 checkbox, then I rechecked it again and exited the bios without saving.
I think it's possible due to my actions in the bios, even though I didn't save any changes, that it reconfigured on reboot from 2 to 4 lane PCIe.
What do you think happened?
Sorry for any confusion and hopefully I haven't cast any shadows over this model NUC, I love it!

可能在M.2 NVMe控制器的第一次初始化期间,您可能通过使用复选框错误配置了控制器,但是很高兴看到您的驱动器现在按预期执行。
Windows可能还有一些后台任务会带走一些驱动器性能。
如果您发现性能下降并且度过美好的一天,请随时通知我们!

Its possible that during the first initialization of the M.2 NVMe controller that you may have misconfigured the controller by using the checkboxes, however it is great to see your drive is now performing as expected.  There is also a possibility that windows may have had some background tasks that were taking away some of the drive performance. 
 
Please keep us informed on if you see more degradation of performance and have a great day!
