Coppermine 600E does 757 with flying colors, but wont even POST @ 600¿¿¿

[-=!ME!=-]

My coppermine 600E does 757 with flying colors, but wont even POST @ 800:( [typo in subject :(]
My CPU runs great @ 757 [6x126]
But when I set my FSB to 133 it just wont boot/post.
I see my vidcard init and then my screens just stays black.
I set my PC133 RAM to CAS 3-3-3.
What would be the problem part¿

Did you try upping the voltage?

[cozyfannytooty]

ME, You don't need to up your voltage at 800Mhz, at least thats what the Overclockers.com reviews with the 600e on Abit and Asus boards have shown. I have that chip and I get 800Mhz at 1.65 and stable on both my Abit boards (SH6 and VT6X4) and can post at 1Ghz (not enough cooling yet). I'll look into your situation more and see what help I can offer, but voltage should not need a change from default. Cozy

Every chip is different; you cant use tests of 1 or 2 chips to predict them all. I'm guessing 99% certainty voltage is your problem. Out of curiosity, cA2, cB0, or cC0 ?

[cozyfannytooty]

Well, okay I'm still a learner. Maybe it is your voltage ME. Please don't fry your chip though. V/R Cozy

Well, if I'm reading your post correctly it says your at 1.58V. That's kinda low. After all, a cb0 coppermine is supposed to run at a default voltage of 1.65v and a cc0 is supposed to run at a default voltage of 1.7v. So, I tend to agree with others here who say you may need to bump up the voltage a bit. A little bit higher voltage isn't going to kill your chips as long as you keep it reasonable. I, myself, wouldn't go over 1.85v, but some people push it even higher.

I noticed, that when i just had my C-mine it ran @ 2V @ 600 for almost a month. :O

I'll bump up the Voltage a bit to see how it does...

There's one thing that hasn't been talked about and that's your temps. Is 38C idle or under load. If it's under load you seem to be OK for now, if it's idle those temps are too high at that low of voltage. The rule of thumb is that it's OK to kick your voltage up .25-.30 at most, providing you have proper cooling. If 38C is your idle temp I would probably venture to say that you'd probably be around 45 at load. Which is about as high as you'd like to go and still have maximum performance. I would find in most cases you'd have to raise your voltage to hit 133FSB, however guys with 600's would no more than I would.

PIII 700@1030 w/alpha, Abit BE6 II, cpu temps idle and under max load 25C/35-38C at 1.9V

38C = @ Full load. All dile time goes to my cow...
600 MhZ = 37C
757 MhZ = 38C
Not much difference, so I guess cooling wont be the limiting factor to 800.

Me.......what's going to generate heat is the upping of your voltage which I assume hasn't been done yet. Hey man your running at 757mhz at default voltage, that ain't bad at all. I've seen no mention of your heat/fan combo unless I've missed it. Most of us like to keep our temps below 40C at max load, but 45 is acceptable to most. Anything over that would suggest better cooling. It's already been suggested that you up your voltage to stablize your system at 800mhz. I would have to agree with that......just keep an eye on those temps. In order for me to be completely stable at 133FSB I have to run my voltage at 1.8. As you can see by my earlier post I'm always under 40C and that's at 1.9V. The clear advantage of a quality heat/fan combo. Up that voltage, live a little, keep an eye on those temps and you should be just fine.

Well Said, Howard!

Thanks Milk Powder, the only thing Me's guilty of is not having a 700 like us.....:))) As I've mentioned before I'd get rid of my kids before I'd get rid of this CPU. Thank God that don't frequent this forum!!!....:)))

[DocClock aka MadClocker]

I would tend to agree and also point out that the cpu heats during bootup as much as if you were running an intense game..voltage and cooling is the answer.
Your screen went black before the mem test? and before the cards init?
Voltage.....1.75 is a good point to get you 800
Good Luck

Just after I see my videocard info.
I DON'T see any BIOS/POST, only my videocard info, then that disappears and the screen goes blank.

I use an Abit SH6 for my slot P3 600e ( sittin' pretty at 830Mhz right now ) with Alpha cooling and 1.65V at 36C to 37C under load. I use the default voltage because of a couple of Overclockers.com articles. One 600e o/c was with the Abit VT6X4 and the other was with an Asus mobo and one or both stated it wasn't necessary to raise the voltage above default until hitting the 900Mhz mark - thus my logic, taken from the more experienced. I was unaware that chip variations with different mobos might present other circumstances. JustCozyFans
