Windows 10: Windows 10 copy speed limits

Hi! My question is about speed limits in windows 10.

My configs:

CPU: AMD Ryzen Threadripper 1950X

MOBO: ASUS X399 ZENITH EXTREME

RAM: G.SKILL TridentZ Series 64GB (4 x 16GB) DDR4 3200 F4-3200C14Q-64GTZ

SSD: RAID0 (2 disks) SAMSUNG 970 EVO M.2 2280 250GB MZ-V7E250BW

System: Windows 10 Pro x64


AS SSD says that raid has 5GB/sec read speed and 3GB/sec write speed.

AIDA64 Cache&Memory Benchmark says that RAM has 98GB/sec read/write/copy speed.


So i created a disk in ram via RamDisk and measured speed by copying one big file between the disks.

Here are results:

RAM>RAM - 1.5 Gigabyte/sec

M.2>M.2 - 1.25 Gigabyte/sec

RAM>M.2 - 1.45 Gigabyte/sec

M.2>RAM - 1.75 Gigabyte/sec

Doesn't matter if to use standard windows copy or to use total commander.


I understand why raid to raid is 1.5GB/s. It's because its write speed 3GB/s is divided by two (read+write,read+write etc).

But what about ram>raid, raid>ram or ram>ram??

Is there any limit in windows?

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Wireless Speed is slow and limited in windows 10

Hello!

I know this topic is asked many times, but I still didn't find any solution for my issue.

The problem is my wireless speed is not normal, it is limited/capped to ~4Mbps (~500KB/s), it should be ~60Mbps to connect to the internet.

I found some points regarding this issue.

• My wireless speed is normal in Ubuntu, with the same device. It means that the problem is not my hardware, the problem is in Windows driver or software.
• My wireless transfer speed is limited to ~4Mbps when I copy a file from a local network location (my PC).
• I tried to install and re-install network drivers.
• I even fresh install windows into a new disk (I just bought a new disk to replace this laptop's old one), and the problem occurs before I install lot of programs.
• The speed still limited using 802.11bg connection (Its different, limited at ~16Mbps).
• I tried many 'common ways' starting from flushing dns, reinstall drivers, and etc.
• My wireless network interface is Qualcomm Atheros AR956x.
• LAN connection using cable does not have any problem.

Any help would be appreciated, thank you very much.

 

Speed limit wrong.

The speed limit is listed at 55 in Ohio on I-77 between Portage Rd. and just north of Fulton Rd. It changed to 65 several years ago.
