SATA HD and OC'ing

I haven't seen this problem posted anywhere else on these boards, so here it is:

First off, specs:

Abit IC7-G Max II
P4 2.6c
2x256 OCZ PC4000 3-4-4-8
ATI 9700 Pro
Seagate 160 GIG S-ATA
Maxtor 120 GIG U-ATA

My problem deals with the Seagate HD and overclocking the CPU. The SATA drive is detected and runs fine when I am running at stock speeds, but the moment I change the FSB in the bios, like from 200 to 203 or 250, the POST (bootup) no longer sees the SATA drive. It sees the U-ATA drive.

I have tried turning off and on all of the settings pertaining to SATA in the bios, no luck. I have noticed that others on here with SATA drives and OC'ed systems have not encountered the same problem.

Is this a HD issue or a motherboard issue? I am going to test another SATA brand this weekend to eleminate the HD aspect.

NOTES: After increasing the FSB and rebooting, the POST Will hang when it is detecting the connected drives. It will detect everything except for the SATA drive after hanging for like a good 20 seconds. When I change the FSB back to defualt (200) the system boots up as usual, no hanging and detects all of the drives. I have also tried connecting the SATA drive to the SATA 1 and SATA 2 slot, same problems.

Sorry for the long post, but I am at wit's end on this issue. Need help!!

Seems like mobo. Did you lock AGP/PCI frequency at 66/33. If you didn't then that's the problem.

By locking, do you mean that I should lock the AGP/PCI at 66/33? Because it does change when I change the FSB.

Hopefully this is the problem. I will give it a shot tomorrow and re-post.

Thanks.

Yes I do mean locking it at 66/33, if it changes when your FSB goes up then it's definently the problem.

I found this article on SATA drives and OC'ing.

http://www.overclockers.com/tips00400/

It specificly mentions my mobo, the IC7-G. I haven't tried locking the AGP/PCI frequency yet, but I am sure that Scott is correct, and that this is the problem I am having. I hope this helps anyone else that is/will have a similar problem. Save yourselves a few headaches.

Dude thats a mobo issue, make sure the PCI and AGU bus is locked to 33/66. If they run too high, the mobo will not be able to recognize it properly or at all..
