*** USB 2.0/ X2 Breakthrough!!! ***
Well I hope it is. After talking with Tony at Epox USA, he mentioned to me that only X2
3800+'s seem to be affected by the freezing issue, and then it occurred to me that AMD released the Manchester 3800+ and then the
TOLEDO 3800+ with the disabled L2 cache (should be Rev JH-E6 in CPU-Z)! Before I get ahead of myself, I should ask, does anyone with something other than the X2 3800+ (Toledo) have this freezing issue?? Another way to put it is: does anyone WITH the X2 3800+ Toledo not have a freezing issue??
My theory is that the disabled L2 cache plays a large role in the freezing issue, but I need more data before I can make any conclusions. Like I know Mem has no freezing issues, but he has a 4400+ X2 I believe. This means he doesn't have that disabled L2 cache and would not have the freezing issues.
The AMD Errata 123 may have something to do with it as well since it fixes an L2 cache issue with X2 processors:
Errata 123 refers to the 123rd bug identified in AMD Athlon and Opteron processors. This bug affects the cache bypass feature in those processors.
These processors have an internal data path that allows the processor to bypass the L2 cache and initiate an early DRAM read for certain cache line fill requests, even before receiving the hit/miss status from the L2 cache.
However, at low core frequencies, the DRAM data read may reach the processor core before it is ready. This causes data corruption and/or the processor to
hang.
Feel free to chime in with your thoughts, but as of now, I think I might be on to something!!!
