Forced to choose between onboard SATA or overclocking: Why?

:Q 😕 :shocked: :thumbsdown:

I recently attempted to add a new WD SATA 200 GB drive to my system. I'm running an Albatron PX865PE Pro II with a P4 2.6 clocked at 250 FSB for 3.25 Ghz and 400 Mhz DDR memory. I have pci/agp/src locked at 33/66/100. The board has the Intel ICH5R controller with 2 SATA channels. I can only boot with the SATA drive connected if I reset everything in the BIOS to default for the CPU and memory. If I overclock the CPU or manually clock the memory to 400 Mhz, the system fails to even POST with the SATA drive connected. In fact, I hear the drive click and spin down immediately when I try to boot. The system reports the CPU and memory, then it just stops...it won't even enter the BIOS. I found a post added to a review of this mobo stating that a user had received an email from Albatron tech support stating that the board does not support SATA when overclocked. My tests confirm this. My question is WHY?

I bought a PCI SATA card and it works fine with the system overclocked. I'm just pissed that I would have to buy an add on card when I have the freakin' controller built in on the mobo.
 
Rant, not a question, you answered all your own questions. :roll:

The SATA controller is not locked, whereas the PCI bus is, so the SATA drive gives up after a small OC. Its an imperfect world so what's new!!!

I have the same problem with my MSI K8T Neo2-F. :frown:
 
If the onboard SATA controller is linked to the FSB, then that would make sense. However, why does it also fail if the CPU is at default, but the memory is clocked at 400 instead of 333?

Click to expand...
Albatron may have meant that they actually built-in a protection mechanism to prevent the use of SATA when the system is overclocked.
