I'd set it to 4GB at one point just to see if it would make any difference at all, but I get the same problems whether it's set at 512MB, 1GB, 2GB or 4GB. It's at 2GB right now and was at 2GB at my previous test when I fetched the performance results.

I should probably mention that this is single player Tekkit, so it's just me. I didn't get to check last time but Java was using a little over 2GB while I had the maximum set to 4GB, and it was killing itself all over the place. Since starting the thread I've also tried uninstalling and reinstalling both Java and the Technic Pack, so I'll add those to the list and have a look for the free RAM in a second. EDIT: Just started up Tekkit again, took all of about five minutes to start running into lag and literally spent the last fifteen minutes trying to get Task Manager up. That's how badly Tekkit slowed everything down. ._. HOWEVER, I did eventually find out that I had ~400MB in both Available and Cached RAM while this was going on. CPU running at 50% but memory at 90%. Please help. DOUBLE EDIT: Also I should probably mention that I can't seem to get any sound in-game since reinstalling the pack, either. I don't know why this is.

Title: Tekkit Lag and Memory Issues, Cannot Resolve Version: 3.0.3/3.0.4 OS: Win 7 64bit Java Version: 1.7.0_06-ea, 64bit Description of Problem: I've been having problems with Tekkit similar to those described by a few others, e.g., game runs very smoothly for ten minutes or so but will suddenly begin to lag after that, severe lag spikes every couple of seconds until the game becomes unplayable. I've tried numerous recommended fixes to resolve this, including: -allocating more memory to the Technic Launcher in the Options menu -allocating less memory to the Technic Launcher in the Options menu -manually allocating more memory to Java -manually allocating more memory to Minecraft -manually allocating more memory to the Technic Launcher -updating Java -telling my graphics card to use MAXIMUM PERFORMANCE when running Java, Minecraft or the Technic Launcher -using a custom texture pack for Tekkit -using Minecraft’s default texture pack -turning down Minecraft’s graphics settings -manually updating my graphics drivers -uninstalling and reinstalling the Technic Pack -uninstalling and reinstalling Java None of it seems to make any difference. My PC runs on an Intel i5, 3.30GHz quad core processor and there is 4GB of RAM available. It runs much more demanding games and programs at full spec with no problem, so I find these issues with Tekkit a bit annoying. Is there anything else I can try? Error Messages: No error messages. I was getting the ~Minecraft has run out of memory~ error before I turned off the custom texture pack, now it's just the lag. Error Log: N/A

I'm having a very similar issue, the game runs perfectly smoothly for maybe ten minutes or so but then it'll start to lag until it eventually becomes unplayable. I was getting the "out of memory" error until I told the game to stop using a custom texture pack and I've turned down as many graphical options as I can but still no dice. :(
