Will try when I have time! knew CPU-Z already, but thanks for the tip Overall I'm happy with the A8V, except is picky about 4 banks of DDR. Will try later Greetings & thanks to all who replied! Steven

Any chance you would consider changing media from Optodisc to Taiyo Yuden (I know you have tried Verbatims)? Regards Hi! Follow up: It did turned out to be a case of bad RAM. I woulden't have known if Imgburn diden't give these error messages. Funny thing is: Memtest86 did not find any errors overnight. However going from 4 sticks to 2 sticks dual channel fixed the errors. While it does support DDR400 with 4 banks it seems rather flaky. It did work when lowering to DDR333 (2T was always on) Setup: AMD X2 3800, Asus A8V Deluxe Thanks everyone! ps: those DVD-RWs are indeed cheep junk but as junky as the are the now verify perfectly Just burned one of these verbatims and they work fine.

Hi! First of all: sorry for my bad english, I'm not native. My problem: miscompare errors on verify What I have done so far: - read this forum - making sure no Daemon tools installed - changed DVD drive for a brand new - tried DVD-R DVD-RWs, Verbatim, .... - Reinstalled Windows XP - Used ASPI instead of SPTI, used VSO instead of SPTI, no change They all fail w/ miscompares:( Can you help me? edit: A burn with Nero fails too when verify Logs: (beware I use debug mode - long) I 16:12:52 Operation Started!
