Not if you bought it through eBay. To replace a working 128MB card, I bought an 8-chip 512MB Crucial RAM SO-DIMM of the correct specification (according to Crucial's website) for a 14" iBook G3/600MHz last August. The new card wasn't seen by the iBook. ASP saw the RAM slot as empty. Apple's Hardware Test CD reported:
DIMM1/J12 Bad Memory
PC133-322, SDRAM
CL3:7.5, CL2:10.0 Cycle (ns)
00-0
Rev. 0000, 00 00, 00
ie, with no data in the last two lines, in contrast with the existing 128MB DIMM:
2C-0, 8LSDT1664LHG-13383
Rev. 0300, 02 01, 08.
I told the seller of this on the day that the card arrived, and asked for an RMA number. I returned the card by registered post, and it was delivered in Hong Kong four weeks after I sent it. The seller had the effrontery to post feedback claiming to have made a refund, which never appeared in my PayPal account, the only avenue for him to make a refund. Neither eBay nor PayPal would get off their behinds to do anything about the matter, which still stands the same eight months later. So I have neither RAM nor refund. Fraud at least, and scarcely distinguishable from theft at best.
Cross your fingers and wish very hard for your refund or replacement.
