800eb question

[IronLungsta]

quick question
System

intel 800eb
asus cuv4x mb
voodoo5500 agp
2 chips of 128 ram 133mhz
sblive
ethernet card 10/100
Win 98 se

Had this bad boy oc'ed to 888 now for awhile with stock fans and avg around 45 C full load. A bit high. This is with the fsb at 148

As soon as i crank it up to 150 mhz Win decides not to boot up and im forced to shut her down. It eventually kicks me back to 400mhz.

Now, my question is why is this happenining? Is it a temp issue?
Have i just reaced the limit with this proccesor?

Any help would be appreciated..
Thanx

Is it generic ram or some type of name brand?
I am having trouble at 150mhz bus with cheap ram. Try setting lower timings w. ur ram

It could also be your NIC. Most NIC's don't like higher PCI bus speeds. Try taking it out and see if it works then.

It could be your temps. I would recommend getting a better HSF than stock. OCZ Gladiator. Mellineum Glacier. Thermalright SK6 are all good HSF's.
Are u using thermal paste or the pad that came w/ the stock HSF?

Your temps are definatly getting up there. The advice given above is good plus you might need to raise your vcore to overclock higher, but this will increace temps so you should get a better heatsink and fan before you do that.

If it was temps that was causing the problems my comp would at least boot up, would it not?
How do u turn down my ram timings?

not allways when i put on my new Gladiator i was able to post and run at 171FSB before that 168 was tops and i only ran 3C cooler with new HSF, the others are rite if you have better cooling [case cooling too] maybe even a HSF for your northbridge you can raise CV and set your memory timings back a bit and you should have no problem getting your CPU to run at higher speeds also you may want to set your BIOS up for stability check www.rojakpot.com and go through there BIOS guide.

What FSB are you running at? if its over 133 then you are running your ram out of spec look for settings like minus clock speed for ram also NS speed, i think if you go through the BIOS guide i pointed out it may explain things better or atleast give you a better background.

I dont know what chipset your running but if its a VIA make sure you disable sideband in registry.

Also some NIC cards do not like to run at out of spec speeds and theres a good chance that may hold you back as well

K cool thanx outhouse...
got it up to 900 but i am now gettin registry errors. Has anyone even heard of this happening, cause its new to me...
When i dont get that reg error its extremely unstable when running practically everything.. My temps never reach above 40 before my system decides to hang, so i dont think its temp related.

Anyone know what could b causing this?

Thanx

What are you using to measure temps? the Asus PC Probe is known to be 10 degrees (+/-), meaning your temps could be hitting as much as 50 degrees. I'm having the same problem, with the registry, and it might be heat related (where the flip is my alpha!!!). The only other thing I can think of, is that you need to try a re-install.

[outhouse]

When you get registry errors it means youve gone a little to high and you need to regain stability, burn it in for a while at a cool higher CV but lower FSB settings and see if that will help after a couple of days of non stop burning with your favorite program thats intensive [i like Seti] As long as your NIC card is not holding you back you may gain stability. One note sometimes hard drives do not like to be overclocked and they can cause registry errors but in this case i believe its just that your pushing your CPU a little to hard.
