RAM on Laptop Toshiba Satellite Pro A300

Hello,

I need an advise. I've just took a 1GB memory module from older model Satellite A200 and put it to my newer model Satellite Pro A300. The following is the information about SPD:

Original one:
Manufacture Date Week 20 / 2009
DIMM1: Kingston (2 GB DDR2-667 DDR2 SDRAM)
@ 333 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 20-43-3-5-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz 4-4-4-12 (CL-RCD-RP-RAS) / 16-34-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)

From old Toshiba:

DIMM3: Samsung M4 70T2953EZ3-CE6
Manufacture Date Week 42 / 2007
@ 333 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 20-35-3-5-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz 4-4-4-12 (CL-RCD-RP-RAS) / 16-28-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)

Accordign to the information was it a good or bad idea? I mean the differences in SPD.

Thanks very much for your time and efforts!
