FSB Wall & FSB Hole

[NoobyDoo]

Can someone please explain what exactly are "FSB Hole" & "FSB Wall". Also, what is the cause/reason for them. Is it a chipset issue/BIOS issue/mobo prob ? Typically are they "fixable", via a BIOS update for example.

Thanks.

My knowledge on this matter is rather limited but I might be able to help shed some light on the matter.
From what I understand:

FSB Wall: This is where your overclocking comes to a screeching halt. Any higher than that point is where your system will not post or boot or function in a stable manner.

FSB Hole: This is an FSB range in which your motherboard will cause a few problems such as not detecting hard drives and such (I think my Foxconn mobo is experiencing this). It also may cause some erratic behaviour.


I hope I helped in some way. I will stand corrected if any of my information is misleading. Hopefully, other posters will help to clear this up.

FSB Wall, the highest FSB your motherboard can handle. You can run total speed less than what your system will perform at, but at the max FSB. So maybe your system will do 525 FSB (6x525-3.15), even though it may run faster (8x400=3.4) So 525 is the wall.

FSB Hole. Motherboards use dividers Some motherboards won't post or run at all at certain speeds. Example: your motherboard won;t work between 380 and 400, but works fine at 401-480, or below 380.
