win98 / win2k overclocking?

[spazm_1999]

I've got my PC running on win98 at 165FSB on one drive and when I installed my win2k on a spare drive it wasn't booting. I lowered the FSB to 133 and it booted. Could this be the HD which is too old to run at 165 FSB or it's really that win2k needs a lot more stability to boot?

P.S. After many try I found that win2k doesn't start at max 140 FSB higher than that, scandisk (DOS) crash.

It really could be either one. I do know that win2k is less tolerant of memory errors and overclocking. If you can run stable in win2k on an overclock, it's almost a sure thing Win9x will be fine.

I would suspect your harddrive is giving to the problems. Post your specs and I bet we can eliminate one or the other.

I thought about memory errors but at 165 my ram is running at 112FSB and I have PC-133.

I did saw something weird when o/c
667 - 47C
700 - 47C
750 - 48C
800 - 50C
825 - 50C (not totally stable)
850 - 53C (not stable)

Then I putted a peltier & water cooler on it.
667 - 64C ....

Specs:
Asus CUSL2-C

Cool! You have the same board I do. This should be easy to communicate, then. You know how to go into your bios and select your harddrive mode, right? Just go to where the Maxtor is, and force it to use either DMA1 or PIO4, if it boots, then your HD can't handle the extra mhz on the PCI bus, if it doesn't, you know you are hitting the ceiling of your CPU.

Yes I forced it at PIO 2 a little before, but it didn't help... but why would it boot at 800 under win98 and not under windows 2000.... could it be because my PC is installed in "standard PC"?

just a question like this, didn't you had problem with ACPI under win2k with that mobo?

I think your processor is giving you some troubles. Some things to try: Set your memory in the bios to 9T,7T (IIRC).

I haven't had any ACPI related problems with the CUSL2-C running the 1003 bios.

Changing the mem for 7T,9T didn't help either.... that's really weird. Here's the setting that I've been able to make work on each OS.

Win98SE (Quantum)
---------
133/133/33
160/120/40

Win 2000 (Maxtor)
---------
133/33/33
140/140/35

I tried 150/112/37 under win2k and it failed.
145/108/36 also failed, but after 5mins under scandisk DOS, it did 4% (the entire drive takes about 30 sec).

Maybe your just more lucky than I for the mobo, my PC just does'nt close with this one.

I bet your maxtor HD just can't handle the bus speed. They are notorious for not being very tolerant of out of spec PCI buses.

Damn... and I didn't wan't to risk all my drive datas by installing it on my HD. Well, it seem that this 2 year old drive has to be remplaced.

Thanks for the help.
