ULTIMATE NETWORKING GUIDE! 

I’ve been having issues playing games and my download speed has worsened these past few months. Contacted my ISP about my issues and they’ve always found excuses not to fix it. Just found this video today and after following it through it really helps me a lot. No more stuttering and packet loss. Truly deserved a like and a sub. Thank you so much for this guide. Have a blessed day man

phenomenal content my guy, keep it up

Excellent videos and advice, no copy+paste theory and all researched and test 👍

Bro you are magician! Day and night difference for my setup!

man u best, it so rlly interesting for listening and understood what of hard work did u do) great job

Thank you savitarax ! Helpful as always..

Niceeeeee vid man 🫶🏼 always nice to learn new things

After watching many videos on youtube to try and optimize my pc without success i was recommended your videos and im glad i was.I love how you explain everything in detail and how you dont just say "do this",you actually explain the effects of changing the setting.....and more importantly my pc is more responsive....thank you

Thanks, needed this!

would be cool if you shared all the commands and registry paths in video description.

I found a restore point thanks for you great videos and your help!

Best network guide i have ever seen good job man you are awesome!

You're a legend

Really very good video, very well explained, and impressive how they inform you of programs and values, and much more to explain every detail of your understanding! I have a question too, you have ever heard about AdditionalWorkerThreads? Is it a thing in performance?

Thanks A LOT man!!

Thanks again for the nice video and those nice tips! How come when you run a speedtest, your NDIS.SYS is running onto 1 core while mine is on 8 cores. I followed the same modification as yours.

video is amazing

Thank you for this! One more thing, there is FastRecieveDatagramThreshold in the same path as fastsenddatagramthreshold. Earlier both of the values were 4000. I changed fastsend registry value to 64000, now wht value should i put fastrecievedatagramthreshold?

I noticed you set the value for FastSendDatagramThreshold for 64000 in hexadecimal. Should it not have been in decimal?

Awesome video (subscribed)! I am a little concern about messing around with UDP and TCP ports though. I don't think that I quite understand the performance benefit of changing the default values. (Start port = 49142, Number of ports = 16384). That's an awful lot of available listening ports for apps to use and unless you are running a Server, not sure that this adds any benefit

Please tell me how to enable large send offload and checksum offload via registery editor, as when i change these settings via network adapter properties and then when i restart my pc, the settings get reverted back to disabled :(

Thank you bro

Hey savitrax what is the notepad on ur desktop about fix for ethernet can u share it in the next video?

Hi, does it matter what RssBaseCpu core you use or is it any that isn't being utilized heavily?

can you do a guide about ur taskmgr and what u have disabled?

It seems that all the Nvidia links lead to deleted pages any chance on making a tutorial for the Nvidia sourced solutions?

Issue 1: When going into latencymon, after having set my RssBaseCpu to core 6, my core 6 still says 0 on the DPC count? Issue 2: When running the set dynamicport command, it just comes up with "Wrong parameter" Issue 3: Jumbo Packet doesnt have the option of disabling or enabling it, it has a value of 1514?

Intel Driver version 26.00 are the last version drivers where there is Rss option. I dont see working Rss in your video, NCard work only with One Core #9, shouldnt it use others cores, RssBaseCpu=9 so 10,11,12. (RSS=4cores), and what about HDAudBus.sys how to change Core for an audio?

Sick! after tweaks i got to 950Mb/s up and down with 3ms latency down and 5 latency up. Hade 75 latency up before the tweaks :O

In this case I cannot change the Buffer Size via Driver settings, how would I change it via regedit?

A couple of notes ... 1) the Nvidia links in description have died. 2) per the MS article on RSS the RssBaseCpu goes in Tcpip, not NDIS, for modern Windows. I did it that way instead and am seeing networking spread across my last 4 CPUs. Might work in either place?

Great video, thanks for providing sources and such. Probably asking for a bit much but some form of before and after comparison in a game or something would be cool to see the effect but it's all good. I saw a tweak go viral among the cod and fortnite community recently, not sure if i can link it in the comments but basically the person disabled ipv6 in network settings properties claiming it'll massively reduce your ping. Any thoughts on that or is it bad to do? Some people said avoid it, others happy with their results. Looking at my adapter properties i've had it disabled for quite some time, is there any drawback?

Thank you for the guide. I am unable to use the RssBaseCpu, despite setting it to Core 9, I still get interrupts on Core 0 and Core 12 in latencymon when running networking intensive tasks. I am running Atlas OS Win11 23H2 on i5 13600KF with HT OFF. My Ethernet Adapter is Realtek Gaming 2.5GbE Family Controller. I am on the latest drivers.

Still cant find how to increase receive and transmit buffer size, there is no Proset Adapter for windows 11 from Intel

i recommend leaving networkthrottlingindex to default hex a or dec 10 as setting it to FFFFFFFF has an impact on dpc latency. and also systemresponsiveness set to 0 is also the same as set to 10, but for me setting it to 10 decreases my dpc latency also, if i set rssbasecpu, do i remove the affinity i set on interrupt affinity policy tool? and im pretty sure the value is supposed to be 64000 for decimal for fastsenddatagramthreshold

Thank you for this video, just wanted to say that some of the command lines for dynamicportrange can vary. On my system for example i had to specify tcp and udp using protocol=tcp or udp. so stuff like that. Commandprompt is great because it shows you possible commands, so if your using this video as a guide and copying commands one for one don't get discouraged. Play around in cmd and you can make it work. Here are my command lines for dynamicport range. C:\WINDOWS\system32>netsh interface ipv4 set dynamicportrange protocol=udp startport=1025 numberofports=64511 Ok. C:\WINDOWS\system32>netsh interface ipv4 set dynamicportrange protocol=tcp startport=1025 numberofports=64511 Ok.

I made my buffers as small as possible to prevent packet loss. and it really works, but I have a big problem with bufferbloat, could increasing the buffers reduce the bufferbloat?

everything you did in command prompt I did on my windows 10 and it said " the parameter is incorrect"

hej ! netsh int udp set global uro=disabled

where u download that proset adapter config util?

can u do one for realtek ethernet users?

Hi i am on a realtek network adapter and i noticed that when i do the rssbasecpu some of the intereputs go onto the core i have chosen but most are still on cpu 0 if you can find a solution i would be very happy and you mentioned some drivers like realtek have receive and transmit buffers at 512 and 128 you are right but i have figured out how to change it you can go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318} then go to the 0000s or 00001 or more depending on your pc but go to the one that has the most stuff then go to ndi then params then select recieve buffers and change the max then go back to adapter options and you can change it

Excellent video! However, adding the DWORD "RssBaseCpu" and setting it to a specified core does not seem to work in my end. I have also tried using the Interrupt Affinity Policy tool and also did not work. Is there any way to fix this problem? I'm on a Realtek Gaming 2.5GbE Family Controller Network Adapter, and AMD Ryzen 5 7600X.

for flow control to work as intended, you need all the devices on the LAN and the switch to have flow control enabled. additionally, it's ancient sauce, so even when working as intended, any misbehaving device on network can make things worse with flow control on. it's basically another point of buffering, which you dont want on a full speed across all ports capable switch. speed and duplex should be auto....and use cat8 cables for best performance i noticed the nvidia recommendation for the datadram threshold is 64k, i.e. 64000 in decimal. you've set yours to 64000 in hex, which is not 64000 decimal

The Nvidia link does not work?

i only have the option for 2 rss cue things should i still put it to 4 in registry?

the latest latencymon (7.20) does not do a great job in displaying dpc usage. my davise try to find a older one

FAST SEND DATAGRAM THRESHOLD Isn't that edited via decimal (64000) instead of hexadecimal? Because I believe that the numeric value is suppose to be shown between the parenthesis.

I cant do: netsh int tcp set global rss - enabled, it says the parameter is incorrect

i want to reset my udp/tcp ports after following this guide can you me tell me wbere to find to reset ports to default value

is this strictly for ethernet or does it also work on wireless

In windows 11, systemresponsiveness will always default to 10 if it's lower than that

I tried the regedit for the cpu set command but that doesn't work the network traffic still gos thorgh the cpu 0

when running the command prompt for the RSS part: netsh int tcp set global rss=enabled

can someone provide the right location for RssBaseCpu and MaxNumRssCpus? please ?

This Sure has kind of lowered my ping in games But what i noitced Was the Stability, now whenever i get a latency spike it only goes up by 50-80ms, (Keep in mind i Played Roblox To test this). While i used to get 100-200ms that would spike up to 600ms now im seeing a stable 89-120 ms and when it spikes it only goes up to 210ms max. Thank you so much.

could i get the latency mon download?

can you clarify if its supposed to be in hex or deci? thanks

Why is Packet and VLAN set to Packet Priority? What does that do?

as someone with limited knowledge of all of this should I just do it the way you have shown in the video. my setup is almost high end 12700k, 3090, 32gb ddr4 ram. i don't feel like verifying if all this will actually only help lol. i see some mixed reactions in the comments on whether this is worth it on or since there are so many variables.

Thank you. After so many years I thought it was just Windows 10 causing my Input Latency It feels like 2009 again 🤰🏿

where do i get this proset configuration utiliy? i downloaded from intel website, but it says that i dont have intel ethernet controller on my pc xD i have intel i225-v

my ndis.sys stuck to CPU 2 even after the reg weak i changed it to 9 ,11 ,4 ...same result .any thoughts . thanx

dude i am waiting for a video from you about microstutter solutions

Is the first tweak supposed to be in hexadecimal ?

Where is your custom OS video bro , been waiting for days.

All nvidia links are invalid.

hey bro , I've tried RssBaseCpu and the interrupt affinity policy but still didn't work

como remover o classpnp do nucleo 0 ?

I got more than 20% increase in download and upload on WIFI and Windows 7, this is a universal guide!

W VIDEO

is it just me or 4:13 RssBaseCpu fix doesnt work? tried multiple cores but nothing seems to work!

MaxNumRssCpus are by default already 4 so u dont need to add it in.

Does anybody know a NIC with on board processor preferably Intel ?

In Microsoft Windows Server 2003 - HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\Tcpip MaxNumRssCpus In Windows Server 2008- HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\Ndis\Parameters In Microsoft Windows Server 2003 - HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters RssBaseCpu In Windows Server 2008 - HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\NDIS\Parameters i have win 10 please tell me witch dword goes in witch folder ?

hey Savitarax, i wanted to ask if you know if its possible to change a process priority and affinity on startup WITHOUT processlasso or wiriting a batch file command ( maybe something like how you made crss.exe run realtime) thanks in advance.

I love your videos they are very helpful, But i have to strain my eyes to see what ur doing cause ur fonts are so small lmao

My RssCPU registry entry was assigned to core 9 just like yours didn't show any interrupts during speed test. What happened?

@Savitarax Windows 10 Home or Pro?

Can you make a video to explain, win32priorityseperation, something "HEX" values, people talk about this.

how do i do any of this LOL is there a step by step

Try not to go blind challenge level impossible

4:22 is not applying idk why please help bro

How does this with gaming? Honest question.

Great content but infuriatingly hard to read and to set out a plan. Can you not include some text ?

Buy dedicated pci nic >

uh? i dont have fastsenddata thingie

Start port : 49152 Number of ports : 16384 xd

ive been having bufferbloat problems for a while, this vid didnt specifically help for that although it helped with everything else. I was wondering if u had any idea on a fix? @Savitarax

Facing double digits latency due to ndis.sys and ntoskrnl. your help will be greatly appreciated.
