fsb over 200mzh

[Shingi]

hi guys,

i have an epox 8k5a2+ i'm running my duron at 200mzh fsb.
i can go faster with the duron, but my pci divider is 1/5 only.

therefore my pci bus is currently at 40 mzh.
i need to know if i push it further than 200fsb and my pci goes
higher than 40mhz, will my pci cards and devices like hardrives and cd-roms
will get damage.

I don't think in general PCI devices are very tolerant of higher bus clocks. I'd be careful with it. I don't think there is much chance (if any) of the devices themselves being damaged, but if they fail due to data transmission errors then you can get data corruption on drives. This has happened to some people with SATA ports that aren't speed locked. In general I wouldn't mess with it unless you have a full backup.

Markbnj,

I'm curious, because I'm thinking of adding a SATA DVD to a SATA controller card. The only thing that I can remember in my bios regarding SATA, is something called SATArom, which can only be enabled or disabled. I have assumed that was simply to enable the onboard SATA controller. Would the addition of the SATA DVD present any problems as far as being in sync with the system? I do not overclock.

I wouldn't OC the pci. Are you saying the divider is locked?

 

[Markbnj]

I wouldn't think it would cause any problems, Seeker, but I have never used a SATA optical drive, so I'm not entirely sure what the implications of that are.

I had an old epox 8KHA+ with a 1700+ tbred, I OC'd it and my wall ended up being the PCI bus since that old board didn't lock anything. The PCI and AGP busses were good up to 38MHz/76MHz respectively but even 1 more MHz out of it and I ran into stability issues and data and display corruption. Thankfully the only data that got scrambled was new files and nothing important

The PCI bus is not lock on the 8k5a2+.

Does anyone know if there is any mod bios out there that enables you lock the PCI or any mod bios that enables a 1/6 pci divider instead of the stock 1/5 PCI divider? for my board specifically, cause i can go beyound 200fsb on my chip?

The FSB isn't necessarily the same clock as the PCI busses. The PCI busses are locked or controllable separately on any decent modern motherboard, I believe.

EDIT: Sorry, upon rereading: the keyword is "decent motherboard."

That being said, I have run my laptop at a 25% OC on everything (no locks) for years with no problems except that the onboard sound doesn't work. That's fine since I have a USB audio thingy that sounds better anyway. That's 41.25MHz...

I don't know if you'll hurt anything, physically anyway. Lockups are to be expected, and I wouldn't do any heavy-duty hard drive copying while you're experimenting with the limits or you might mess up your data. CHKDSK will usually fix anything that may go wrong there...
