Advice needed on an overclock - Tech Support Forums

Hi everybody!

I just received my 2100+ today and installed it. It runs great. It is a T-Bred B, from the markings, which is what was advertised, so I am happy.

I can get this bugger to run at 147 fsb and 150 fsb, but the PCI shows up as running at 35.7 MHz and 30.0 MHz. The system runs fine with full load at sub-40C temperatures (Thermalright SLK-800 with 80mm Enermax fan).

Should I worry about my hard drives with these settings?

I have had so many drives fail in the past, that I really want to baby the drives. The drive is a Maxtor 60GB drive 7200rpm 8MB buffer.

My motherboard is a ECS K7S5A, and I have the CHEEPO BIOS installed. This at least allows me to OC, but I only have a few settings I can choose from.
Available settings (no voltage manipulation available):
133/133 135/135 137/137 143/143 147/147 150/150 166/166

I tried at 166/166 and the system won't boot. There have been documented problems with the 166/166 setting on this board, yet it has not been fixed yet.

System specs:
AMD Athlon XP 2100+ (T-Bred B)
ECS K7S5A (CHEEPO BIOS) onboard lan and sound
2 sticks Crucial PC2100 512MB (1024MB total)
Abit Siluro GeForce 4 Ti4200 64MB TV out with ITES cooling system (externally vented cooler)
Leadtek WinFast TV2000 XP tv card
Toshiba 16x DVD
Lite-On 16x burner
Maxtor 60GB 7200 rpm 8MB buffer
Maxtor 3.1 GB 5400rpm
Enermax 350W dual fan PSU
ThermalRight SLK-800(A?) w/ 80mm Enermax fan w/ manually altered speed control
5 80mm case fans
1 92mm case fan

ThankS!
Dave

Sorry I can't help you dave... I know nothing of how hard drives figure into an overclock. But I thought maybe this thread could use a *bump*.

Sometimes it's the controller that screws up the hard disk.
I have rarely had trouble with a PCI frequency under 37MHz.
The exception was an early Promise Ultra66 that did not care to operate above 35MHz. No damage done, just windows errors. I would think you would be OK using standard 80 conductor ribbon cables in place of rounded cables though. I suspect the rounded cables are more prone to cross-talk between data lines.

Thats a bummer. That 2100 b should run at 166 no problem.

yeah, it definitely will. but prob not w that mobo. i have one running at 2375 ( about at a 197FSB, I believe ). but that is on a much more OC friendly mobo.

back to the question, under 37 w the PCI should be fine, especially with that Maxtor.

The PCI and AGP buses, which usually run more slowly than the frontside bus, use dividers to reduce the clock speed.

daveleau,

Out of 4 ECS K7S5A which I was able to overclock pass 143fsb, I never have any problem with the hard drive being corrupted or going bad. The only one hard drive I ever rma'd was an IBM, it went bad after 6 months and I think that batch was bad. The replacement is still running good. I mainly use maxtor and wd. Normally do not buy hard drives online, just B&M locally.

Been lucky with hard drives.
