chopper Posted May 11, 2005 Posted May 11, 2005 Does anyone know if there is a BIOS available that fixes the A64 sub zero bug? Seems I have it on my Winnie 3200. Many thanks, C Share this post Link to post Share on other sites More sharing options...
spdiscus Posted May 11, 2005 Posted May 11, 2005 I think that's a Winchester (hardware) thing, not a BIOS bug. Share this post Link to post Share on other sites More sharing options...
magg Posted May 11, 2005 Posted May 11, 2005 Lol, same thing I said on EOCF... it's a memory controller thing, not something you can change. Only by buying a new chip Share this post Link to post Share on other sites More sharing options...
FX-WANNA-B Posted May 12, 2005 Posted May 12, 2005 I am getting -117 degrees Celsius in bios with my 4000+ Clawhammer. I was wondering the same thing. Share this post Link to post Share on other sites More sharing options...

Vista Posted May 12, 2005 Posted May 12, 2005 OK. It's just that some people have said that a BIOS update 'might' fix it.That was on the MSI board, this is a different fish. It's never been completely isolated down to the CPU vs. MB level, since not enough people have tried what you are attempting with enough chips and boards. For now, it's just a mystery and your mileage will vary from install to install. Share this post Link to post Share on other sites More sharing options...
chopper Posted May 12, 2005 Posted May 12, 2005 I've 'upgraded' if you can call it that from a AS8 3rd Eye with 3500 Winnie to this DFI and 3200 on the basis that I wanted to go with PCI-E and I couldn't overclock the 3500 because of a memory controller issue. I guess it is worth using the 3500 at the stage to see if it was the motherboard as this processor definately ran 24/7 subzero. What processor should I buy next? Does the FX range sufer this problem?

A64 Posted May 12, 2005 Posted May 12, 2005 what's sub zero bug ??? Share this post Link to post Share on other sites More sharing options...
chopper Posted May 12, 2005 Posted May 12, 2005 Where the processor won't run at Sub Zero temps ! Share this post Link to post Share on other sites More sharing options...
Vista Posted May 12, 2005 Posted May 12, 2005 chopper, from what I can gather this problem is mostly associated with Winchesters and temps below -20°C. Some people think it is the 90nm core, so maybe a San Diego would have the same problem, while Newcastles may be less prone to the issue. Other people have no problems with sub zero and Winnies, so it's not a 100% kind of thing. I haven't seen reports using AMD mobile or Sandy 90nm's yet with sub zero cooling, so the jury is still out on that. However, if it is something that can be cured with the right BIOS settings, your DFI BIOS has more flexibility than any other board out there, and the components are top-notch. I'd lean toward trying some cheap Newcastles and see if you can find a sweet one to super cool, or wait for more data on the new cores.

chopper Posted May 12, 2005 Posted May 12, 2005 BTW. This 600W OCZ PSU Seems ok (your sig). Share this post Link to post Share on other sites More sharing options...
chopper Posted May 12, 2005 Posted May 12, 2005 Yeah. I guess but I really need this machine up and running ! Think I might go for an FX55. I hope they don't have any problems ! Share this post Link to post Share on other sites More sharing options...
