似乎沒有網友提到，所以小弟三八藉此討論串提一下。

-------------------------------------------
1) Celeron D (256K L2 cache) and Willamette (also 256K L2 cache) now have different implementations for several FFT sizes. This results in an improvement of several percent for the Celeron D.
2) A bug that caused some machines to generate "Error 2252" when communicating with the server was fixed.
3) SSE2 trial factoring code had a bug when factoring very large exponents.

--------------------------------------------
1) For SSE2 machines the larger FFTs have been changed to more effectively use a wide variety of L2 cache sizes. The previous version was optimized for a 256KB L2 cache only. Depending on your CPU and FFT size, you could see an improvement of several percent.
2) As a side "benefit" even larger FFT sizes are now supported. This allows testing of exponents up to 596 million. Not recommended.
3) The factoring breakeven points have been recalculated using my 2 GHz P4. This version of prime95 will do less trial factoring.
4) Since server database crashes cause spurious error 3 messages, prime95 will now ignore error 3 messages from the server for 72 hours. This should workaround the problem whereby a result is reported but no CPU credit is given and the reservation is not cleared.
5) Fixed crash bug trial factoring exponents above 286 million.
