You're wrong. The CD-RW disks you used are made by different companies
and have diffrent speed limits hardcoded in them.
This CD-RW has a 4x speed limit hardcoded in it:
ATIP info from disk:
Indicated writing power: 6
Is not unrestricted
Is not erasable
Disk sub type: Medium Type C, low Beta category (C-) (6)
ATIP start of lead in: -11231 (97:32/19)
ATIP start of lead out: 359848 (79:59/73)
Disk type: Short strategy type (Phthalocyanine or
similar)
Manuf. index: 27
Manufacturer: Prodisc Technology Inc.
Blocks total: 359848 Blocks current: 359848 Blocks
remaining: 42982
Starting to write CD/DVD at speed 4 in write mode for
single session.
This CD-RW has a 10x or greater speed limit hardcoded in it:

ATIP info from disk:
Indicated writing power: 3
Reference speed: 6
Is not unrestricted
Is erasable
Disk sub type: High speed Rewritable (CAV) media (1)
ATIP start of lead in: -11940 (97:22/60)
ATIP start of lead out: 335975 (74:41/50)
speed low: 4 speed high: 8
power mult factor: 1 5
recommended erase/write power: 5
A2 values: 00 00 00
Disk type: Phase change
Manuf. index: 43
Manufacturer: Acer Media Technology, Inc.
Blocks total: 335975 Blocks current: 335975
Blocks remaining: 22593
Starting to write CD/DVD at speed 10 in write mode for single session.
They're *NOT* the same kind of CD-RW media. Do yourself a favor and
read a FAQ or book on how CD-RW drives work before giving other people
advice on them.
There are two kinds of CD-RW media 1x-4x ones and 10x and higher
speed ones. They *ARE NOT* the same technology.
1x-4x CD-RW media
Disk sub type: Medium Type C, low Beta category (C-) (6)
Disk type: Short strategy type (Phthalocyanine or similar)
10x+ CD-RW media
Disk sub type: High speed Rewritable (CAV) media (1)
Disk type: Phase change
