Minecraft Server won't take more than 1.5GB

[RedEdain]

Hi there!

 

Basically, I have this modded server on a dedicated computer 

SPECS:

Intel Xeon X5650 @2,7GHz (No overclock yet)

8GB of DDR3 RAM @1333MHz

Seagate 1TB 7200RPM HDD

Windows 10 Pro 64-bit, might change for Linux 

(If anything else is needed, feel free to ask)

 

I won't run anything else on the computer so I was willing to use 5-6GB of RAM for my server, since it has 48 mods on it. The point is I can't put anymore than 1500M of RAM for it or it will tell that it can't run on more memory. I was told by searching on internet that my Java needed to be in 64-bit. Which it is. I was also told that my OS needed to be 64-bit, and it is. But still, the server won't boot up with more than 1.5 GB.

 

I am running a 1.12.2 Forge server (version 2847) with the .jar.

 

TIA!

Have you tried a code like this? This is mine. Not 48 mods though just 24

 

Spoiler

java -Xmx4096M -Xms4096M -jar forge.jar nogui
PAUSE

Yes, that is how I started my server with 1.5GB of RAM (Xms and Xmx to 1500M) and as soon as I tried to put more it wouldn't work.

You are launching the minecraft server jar file right, not the forge one?

Yep, still doesn't work

Try launching the .bat file with forge.jar?

It gives the same result.

 

Invalid maximum heap size: -Xmx4096M

The specified size exceeds the maximum representable size.

Make sure you are using 64bit Java btw.

 

Here's my starting script that is heavily modified for performance improvement by taking advantage of all that the garbage collection has to offer.

Starting Script: (Note the end portion will need your changing) This starts it at 5gb.

java -Xms5G -Xmx5G -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:G1MixedGCLiveThresholdPercent=35 -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -Dusing.aikars.flags=mcflags.emc.gs -jar YOURSERVERJARNAME.jar

It gives again the same error shown in my lastest reply.

 

How can I be absolutely sure that I'm running 64-bit Java? (Which I'm now doubting I am)

[x17andrew71x]

Link to Java 64bit JRE: Download Link
(Oracle requires account creation)

Open Command Prompt >> Type in: "java -version" (no quotes, there is a space after java)

java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) Client VM (build 25.241-b07, mixed mode)

 

This is the result I get

Should look something like this:

Looks like I didn't had the right version. I found how to download the proper one and it is now working, thank you so much!

You do not have 64bit java, download and install the version provided above in the link posted previously. You will need to create an oracle account, they've now forced that requirement. But its free, just annoying...

Glad to be of assistance! Disregard my late reply.
Shoot me a message if you need any further help.
