# How to change the burning buffer size (Regedit/Hex) in CDSPeed

The explanations I found around were way over my head, so I wonder if someone could tell me very plainly* how to set this buffer to 80Mb…

*Plainly = which hex number to enter in the relevant Reg key value, I don’t need a course about how to edit Reg values, I’m not THAT dumb…

To narrow the question, I’ll put a reminder:

So basically I just need someone to help me translate my 80Mb in Hex values… yeah, I find myslef unable to do that… gosh I’m so ashamed… :o

Do [I]amount you want [in MB][/I] x 1024 [KB] divided by 64 [KB]…

That’s taking how many MB you want, converting it to how many KB you want, then telling you how many blocks of 64 KB that would be.

So 80 MB:

80 MB x 1024 KB = 81920 KB

81920 KB divided by 64 KB = [B][I]1280[/I][/B] blocks of 64 KB

This works out, since 4 times 20 MB is 80 MB, and 4 times 320 blocks is [I][B]1280[/B][/I] blocks.

Rough guess with help from calc.exe:
80MB–> 1280 --> 500h

EDIT: Too late. And Albert’s reply is much nicer

Well, that was much simpler than I thought.

Actually I realize only now that dword isn’t hex in the least.
