In conclusion to our extensive discussion I would like to say a few words to those Asus P5K Deluxe owners who for some reason believe that it changes FSB Strap at 500MHz. In reality there is no Strap changing whatsoever and cannot be. All tests that allegedly prove this statement haven’t been performed correctly. The thing is that if the DRAM Static Read Control parameter is set to Auto, the mainboard changes its value at this frequency. That is why the performance drops, which is erroneously considered to be caused by Strap changing. To eliminate this unpleasant effect, you should set DRAM Static Read Control to Enabled in the BIOS Setup.
Am I the only one who actually set the Dram Static Read Control from AUTO to Enabled???
It's EVA2000 who referred this link to us on I4memory and mentioned that there's no negative effect of strap change for 0404 BIOS but yet I still see everyone including EVA2000 setting DRAM Static Read Control to AUTO..
