Set write buffer above 512MB?

[Rex Dart]

How can I set the buffer over 512MB? I've tried messing in the windows registry without any luck. I've got at least 2GB free RAM at any given time, so I'd like to set the buffer higher to reduce HDD access while burning.

Do you really need it that high? If you are having buffering issues a few things you can try (besides going overboard on the buffer size itself).

 

Try not to do too many things that are taxing to your hd, which can affect the buffer. Update your controller drivers, and if you haven't run defrag in a while you might want to.

 

If though you aren't having such issues, then just go with 512MB, but even that is going overboard. This is only if you are getting buffer underruns, is when you might consider increasing the size.

 

If it ain't broke, don't fix it.

Yeah, it's broke. And I want to use my computer for other things while it's burning at a mere 2.4x, so I don't see how this would be overkill. Why not let the user decide that?

 

So, no fix?

Increasing the buffer size does not necessarily guarantee you won't get buffer underruns if you do decide to do other activities that can potentially drain the buffer away from imgburn. If you really want more than 512MB, perhaps try making a request in the suggestions forum.

 

I very much doubt also you are really burning at 2.4x all the time. Have you checked your logs? I am willing to bet you will get write-speed miscompare warnings and you might actually be burning at faster rates since some discs/drives do not support going at slower speeds.

"16:21:02 Average Write Rate: 3,124 KB/s (2.3x) - Maximum Write Rate: 3,360 KB/s (2.4x)"

It should be 2.4x, I would assume... discs and drive claim to support it.

The buffer size limit is 512 MB, which is much larger than any other burning software will allow, and if that isn't enough, you could always create a ramdisk/ramdrive.
