I bought some Samsung PC1066 RDRAM modules from componentsdirect.com and they were remarked PC800. They tried to be clever by sticking a "Warranty Void if Removed" sticker over the part of the label that said PC800. After several phone calls, they've agreed to send me some Kingston modules instead.
DON'T BUY FROM COMPONENTSDIRECT.COM
Here's what the Better Business Bureau has to say abou them.
Bureau File Experience
We rate this company as having an unsatisfactory business performance record based on a pattern of unanswered customer complaints. Some complainants allege the company fails to deliver ordered products. Other customers complain the company fails to issue refunds for returns or cancelled orders. The company responds to some complaints by shipping late orders, or, in some cases issuing requested refunds. A few complaints are closed as disputed, the customers are not always satisfied with the company's response. Many other complaints remain unanswered. The Better Business Bureau does not endorse, recommend or dissapprove of any company, product or service.
