NEC 2510 8x ritek being recognized as 4x

I dunno what’s going on my 8x ritek discs are being recognized as 4x.

has anyone experience this problem?

many drives limit RITEKR03 revision 01 to 4X due to quality issues that arose at the start of this medias’ production.
Most recent discs burn very well at 8X.
If you update to Herries’ 107 HV2B5 they will burn at 8X.

ah fixed it. updated to latest fw 2.16 ritekg05 now seen as 8x.
