160MHz FSB -> TOO HIGH???

So that we all know the background, here are my system specs:

PSU: Enermax 365W
Mobo: IWILL KK266
CPU: Factory Unlocked Duron 650MHz
HSFs: Taisol CGK742092 on CPU & Blue Orb on NorthBridge
RAM: 2 x 256mb PC133 Mushkin rev1.5 (Faster settings in BIOS/SPD2/4-Way on)
HDD(1): IBM 75GXP 15GB
HDD(2): IBM 75GXP 30GB
CD-ROM: Teac 40x IDE
CD-RW: Yamaha 8824SZ
SCSI Controller: Adaptec 2930U
NIC: NetGear FX310TX
Video: 3dfx VooDoo3 1000 16mb
OS: W2K Pro

Now, I have been able to run this system up to 160MHz FSB with a 5.0 multiplier (I am there right now) without encountering any noticeable problems. I could probably go higher, up to 165MHz, but that would be it. MY CPU's limit seems to be 853+ MHz...she just wont boot beyond that without errors (even at max V).

The only modification I have made to my base setup beyond this configuration is to tell the NIC not to AutoSense its connection to the LAN, rather I specify it in the properties.

If I run my system at this FSB, what are the dangers I will encounter? I realize PCI and AGP dividers are high, but have I gone TOO far? My biggest fear is lost data and data corruption as this is a production box for data and model simulations. I could always back down to something more reasonable like 5.5 x 150 or 6.0 x 140, but would rather juice all I can outta this rig

I would appreciate any feedback and suggestions or concerns others have about running my FSB this high.

Thanks...
 
Possible data corruption. Do some drive benchmarks to make sure this isn't a problem. I have a 2940W SCSI card that doesn't like to be OCed one bit.
 
Thanks for the warning. I am going to back things down a bit to something in the 140-150MHz range and work from there. I would rather be safe AND have a little more CPU power to boot!
 
dont we all wish we had the problem of running fsb at 160......damn.....wish i could hit 150!!!145 even....lol😀
 
The key: a solid motherboard and quality RAM. In this case an IWILL KK266 mobo and Mushkin RAM. Though I can hit 160MHz, I am not going to stay there. My comfort zone is going to be 5.5 x 152MHz.
 
I'm SCSI+CPU limited in my FSB, the system was stable (w/ the exception of the SCSI foo) at 150MHz FSB but I had to bump the CPU voltage to 1.875 for 7x150 (1.05GHz) vs. 1.8 for 7.5x133 (1GHz), I ran it for a week at 7x145@1.825V

Damn do I need to get a 2940UW, this old 2940W (yes, old even for the 2940 line) doesn't even like 36MHz PCI 🙁
 
I would go straight for one of the Adaptec **160 cards, like a 19160. No point in not having the upgradability down the line.

Just my $0.02 worth...
 
JPS: when it's a diff of getting a used card cheap or a new 29160 for something like $200, that really matters to me, and the speed isn't what I have SCSI drives for (my main drive is IDE, all others are SCSI)
 
Being on tight bidget myself I totally here DX. Just suggesting that for you seem to know what is holding you back from upping your FSB, and it is fixable if you wanna spend some cash. If it is not not worth it, then hey, don't do it!
