People with PCI-E vga cards should have " Overclock Mode at CPU,PCI-E, ASync", with PCI-E clock at 100MHz; and of course PCI clock at 33.33Mhz. Whereas AGP users can have "Sync or Async" selected. However, my personal experience with both 4coredual-vsta and 4coredual-sata2, agp setups, is that overclocking is better served with "Async" selected and PCIE Clock set greater than 100MHz (based obviously on trial and error testing) ---> for example, my current E4400/4coredual/7800gs agp setup overclocks more stable at 320 when pcie clock has been set to 119Mhz. Of course, simply selecting "CPU,PCI-E, Sync" would also have caused the pcie clock to be set higher than 100MHz. However for some reason the 118MHz which was being automatically set because of my 320 fsb was just not as stable as when having it manually set at 119Mhz? On the other hand, when fitted with an old 7600gs PCI-E card, overclocking stable at 300 levels becomes almost impossible with PCI-E clock at anything above 103MHz --> so with pcie vga card, for me, pcie clock is best left at 100MHz.
Yep. But thats for the predessors of the 4CoreDual-Sata2. The 4CoreDual-Sata2 only has Auto, Sync with CPU, or 100mhz as the options. No way to input a value.
Boot Failure Guard should be at "enabled", since this function is all about helping to recover from a bad overclock, or "stupid" bios settings.
Yeah, Boot Failure Guard can be set either way, but it has never saved me from having to clear cmos with the jumper though.
Your statement on available Overclock Mode options is clearly not true since my 4coredual-sata2 (bios v1.80), which I am currently using to write this posting, has options of "AUTO", "CPU,PCI-E, Sync" and "CPU,PCI-E, Async". And as stated before, changes to PCI-E clock settings is done in "CPU,PCI-E, Async" mode !
Very very weird.
I am also using bios v1.80 on my 4CoreDual-Sata2. I just rebooted and went back into bios to double check. Sure enough my only available options are : "Auto" "Sync with CPU" "100MHz". Sadly, I gots no "CPU,PCI-E, Sync" and "CPU,PCI-E, Async" available jimmor.
Where did you download your bios update from ? I got mine from
http://www.asrock.com/mb/downl...=4CoreDual-SATA2&s=775
What is the revision number of your board, between the pci slots ? Mine is Rev. G/A 1.02
Definitely weird on your part !
My 4coredual-sata2 mobo is Rev G/A 1.02, and my 1.80 bios, like all I have used since 1.10 that came with mobo, was downloaded from same asrock website.
And all three Overclock mode options are available with "any" version bios on my setup ---> so doesn't make sense that you can't see them ?
So with for example bios "auto" as the highlighted option, you are not able to toggle through the three different selections using your keyboard Number-pad's large "+" key ?
Also, not to confuse things, I generally, when available, use the modded versions of asrock bioses which provide proper operation of the EIST/Speedstep options which asrock have "switched off". Strangely enough, when challenged on the missing EIST/Speedstep options, Asrock sent me a "modded" bios asking me not to spread it around as it was not formally recognised ?
For anyone interested in EIST/Speedstep on a 4coredual-sata2 mobo, the latest modded version 1.80A bios is available from the link below:-
