I guess I'll give Newegg a call and see if I can get a new one.
Or should I call AMD?
Since it's a recently bought retail CPU (you did say stock HSF) you should be able to get a replacement through NewEgg. If NewEgg will not honor their warranty due to user error or because it is retail, you can try AMD. Here's the info from AMD's site:
Processor In a Box Warranty:
AMD provides a three (3) year limited warranty on its line of boxed microprocessors. To obtain warranty service for your AMD microprocessor, contact your computer system manufacturer, distributor or reseller during the systems warranty period. After your computer system warranty has expired, you should contact AMD at (408) 749-AMD9 in the U.S. only, fax 852-295-63996 in Asia, and 44 (0) 1276-803187 in Europe. Please be prepared to provide:
Your name, address, and telephone number;
Proof of purchase (including place and date product purchased). You will be asked to fax or e-mail this verification to AMD;
Description of the type of processor you have (K6-2, K6-III, Athlon, or Duron);
Confirmation that the product to which you are inquiring is a retail Process in a Box (with heatsink and fan attached), and not a non-boxed product (processor only);
A description of the computer system including the brand and model;
The brand, model, and revision number of the motherboard supporting the processor and confirmation that the motherboard appears on the AMD Athlon Processor, AMD Duron Processor, or AMD-K6 Family Processor approved motherboard list;
An explanation of the problem.
I don't think SOYO is on AMD's recommended motherboard list though...
Here's Newegg's return policy as well:
There is no replacement or refund guarantee of any kind for any retail package processors, routers, software, blank media cartridges, or any specially ordered items. There is likewise no replacement or refund guarantee covering any product that is affected by any "Year 2000" compliance problem.
