Masked Compression (Ultimate compression in one go)

[gotitpakn]

i have been plagued with general (de) compression errors in xz , any ideas where i should look to correct this ?

appears to have to do with the low amount of ram i have,on win7x64 4gb ram of which 2.25gb is reserved, so 1.75gb available ram. could some one help me with the info i need to mod the file or upload a version of arc.ini optimized for my low ram system. tottal noob to this so not sure what proper amount of ram to alot in the arc.ini

msr gives me error but cannot figure where to adjust ram used for it in the arc.ini, then last run . would like to get it figured out
