no? java will automatically use more ram if it needs it (also, the minecraft launcher allows you to choose how much run it starts out with allocated, although, 6gb is ridiculous, never had minecraft go over 1gb (client wise, server wise i max out at 2gb)
http://blogs.vmware.com/apps/2011/06/taking-a-closer-look-at-sizing-the-java-process.html JVM is funny about memory. Minecraft default is for 1024mb, FTB 2048.
Actually, nope. You can view the changelogs for yourself, that has not changed. 2011 introduced SE7 JVM support for dynamic languages, with the new invokedynamic bytecode under JSR-292,[SUP][91][/SUP] following the prototyping work currently done on the Multi Language Virtual Machine Compressed 64-bit pointers[SUP][92][/SUP] (available in Java 6 with -XX:+UseCompressedOops)[SUP][93][/SUP] These small language changes (grouped under a project named Coin):[SUP][94][/SUP] Strings in switch[SUP][95][/SUP] Automatic resource management in try-statement[SUP][96][/SUP] Improved type inference for generic instance creation, aka the diamond operator <>[SUP][97][/SUP] Simplified varargs method declaration[SUP][98][/SUP] Binary integer literals[SUP][99][/SUP] Allowing underscores in numeric literals[SUP][100][/SUP] Catching multiple exception types and rethrowing exceptions with improved type checking[SUP][101][/SUP] Concurrency utilities under JSR 166[SUP][102][/SUP] New file I/O library to enhance platform independence and add support for metadata and symbolic links. The new packages are java.nio.file and java.nio.file.attribute[SUP][103][/SUP][SUP][104][/SUP] Timsort is used to sort arrays instead of merge sort Library-level support for elliptic curve cryptography algorithms An XRender pipeline for Java 2D, which improves handling of features specific to modern GPUs New platform APIs for the graphics features originally implemented in version 6u10 as unsupported APIs[SUP][105][/SUP] Enhanced library-level support for new network protocols, including SCTP and Sockets Direct Protocol Upstream updates to XML and Unicode Since then we've had one hell of alot of bug fixes and security fixes. Some more security fixes, a few security fixes, 1 or 2 additional security fixes and I'll stop here because I think I have demonstrated the point that java is a security hole ridden nightmare for whatever reason (hell, most OSX malware known infects via java). Hardfloat ARMv6 support, Retina display support (aka, we changed a dpi setting that it was possible to do already), some changes to the time apis and the introduction of JavaFX to the standard SDK installation. Memory management has remained the same.
no, that's incorrect, java can, and WILL, allocate more ram when needed, idk where the hell you're getting that info, but java allocates itself more ram when needed, it has for quite a while, for example i can limit java to 512 mb and when it needs more it uses more, bypassing the allocation settings
That is from GNU Octave which is a programming language targetting the JVM. There is also some good info on it here: http://www.kdgregory.com/index.php?page=java.outOfMemory It is all deliberate. - - - Updated - - - Its all over the internet dude, its even on the oracle technical documentation if you wish to read it. You are the *only* source I can find claiming it autoallocates.
Java can not possibly use more RAM than you allocate to it. It will allocate portions of that limit to itself, but it will never go beyond your set limit... do you even java bro?
yes, actually i do, i've made a custom mod for minecraft using forge, and whenever i limit java to 512mb, it usually ends up needing more, so it gives itself more, it always has for me
See I can immediately tell that you know you are wrong now, normally if I was genuinely wrong you would have link spammed me with something to back up your point, yet you havent, I however can back up my claims and already provided sources. http://stackoverflow.com/questions/11597563/how-to-set-jvm-to-have-more-1gb-stack-size http://www.minecraftforum.net/topic/228873-change-java-memory-usage-re-crashing-fix/ http://forum.feed-the-beast.com/threads/suggestion-disable-ram-maximum.12831/ https://www.java.net/node/653815 https://www.java.net/node/646513 http://www.overclock.net/t/956198/how-do-i-increase-minecrafts-memory-limit http://www.wikihow.com/Increase-Java-Memory-in-Windows-7 http://www.mathworks.co.uk/matlabcentral/newsreader/view_thread/167434 http://serverfault.com/questions/336750/how-does-my-jre-exceed-its-heap-limits Also I speak from experience having hit that limit when a bug in my own java code caused a loop to never terminate and repeat creating additional objects until the JVM hit its own memory limit and crashed on 1.7.40
^^^^^^ always happens for me, in all my experience with java, it has ALWAYS, auto allocated, past my allocation limit when it really needs it, maybe i'm getting lucky, or my java is bugged, idk, but it's fine, because it only does it, when it does in fact actually need it
Because my new PC is up and running, here are the full specs: Mobo: Asrock z87 Extreme9/ac GPU: EVGA 780 ti Superclocked 3GB DDR5 CPU: i7 4770k @ 3.5 GHZ Memory: 2 TB Western digital HDD, 120 gb & 500 gb 840 EVO Samsung ssd's RAM: G.skill sniper 16 gb PSU: Corsair 860i Case: Coolermaster Cosmos SE w/ window OS: Windows 8.1 Pro Full edition Optical drive: Some random LG There it is. My full new build. It is running beautifully.
okay so i've upgraded since the last time I replied to this thread. I now have A Intel Core 2 Quad Q9500 @ 2.844 GHz, ASUS IPIBL-LB Gigabyte AMD Radeon HD 4870 1 GB 6 GB DDR2 2x 500 GB HDDs in Raid0. Delta OEM 460W HP Micro-ATX OEM Case Windows 8. I get about 30-50 FPS (varying) on the default grid map with low-med settings (low mesh, high res textures, normal shader quality, no AA, 16x AF, low shader quality, Ambient Occlusion on high, HDR enabled) I'm planing on getting a 750 Ti seeing as I have high hopes for maxwell looking at the power consumption and the performance/watt
I know only that my PC has a 2,6 GHz CPU, a 19 inch LCD monitor and gets about 13 FPS on grid map (RoR) and about 0,1 FPS on Desert Trails (also RoR).
ASUS N750JV-4103 CPU: Intel i7-4700HQ (2.4GHz, 3.4GHz Turbo, 6MB Cache) GPU: Nvidia GT 750m RAM: 8GB 1x DDR3 1600MHz OS: Windows 8.1 x64 HDD: 750GB
