I missed the ghz club by 5 mhz

[ebola]

I had my new celly 566 running at 995 stable this morning at 1.9 v. i think i would probably need a ridiculous amount of voltage to get it up to 1ghz running fully optimised. its not worth it if you diable shadowing because you lose out too big.

at 995 i had everything enabled on the board so i wasn't taking any performance hits. it gets a bit warm so i'll probably wait till i get more cooling before i keep it higher than 850.

Read the BIOS optimization guide! Shadowing and Caching BIOS, VideoBIOS etc. into RAM isn't really much faster and it can cause system instability! Try disabling it all, and see if you can get just those few Mhz's more...

well i did disable it and my stats went to crap and i had worse performance. it runs faster when everything is enabled.

Thats still one He|| of an oc ebola, you should be very content with that. More than a 50% oc is quite a feat. Really whats 5mhz? i know it'd be nice to have but thats definitly a keeper right there. Way to be ebola.

OpenFriday had a good point, what's 5 MHz amongst friends?? A LOT!! hehe Braggin' rights to say that you hit the magical 1 GHz plateau. ESPECIALLY with a C566. Over 950 with one of these is doin' REALLY well!!

Now, let me ask two important questions.....

1) What are you using for a hsf on this??

2) I'm assuming you're slocket mounted, on a slot 1 board. What board and slocket?

Now, let me put a smile on your face, and give ya some hope.....

My C600 ran solid as a rock at 1009MHz for a long time, with a Gorb cooling it. Went from the Gorb to an Alpha PEP66T, and dropped a bunch of degrees, celcius. I then swapped out the board, replacing the A-Trend/Via chipset, with a Soyo 6BA+III, BX chipset board. Between the two, I suddenly found myself at 1053 MHz, at the same vcore I was running 1009 at.

You need only ONE MHz of FSB for the magic GHz. Keep pluggin away, I guarrantee you will find IT!!

BTW, Ebola....it says in my "sig" ....1053 @ 2.05v. this chip is stable at 1017 at 1.9v, as well.

I wouldn't go any higher with the vcore with yours. Well....maybe to 1.95v, BRIEFLY, just to see what might happen, and then go back to 1.9v.

Congrats on a pisser o/c, too.

its a sweet chip. i got it from batboy. its a celeron 566 cbo stepping

1. im using a alpha pal 6035 heatsink.
2. im using an iwill slotkit on an abit bx6 rev 2 motherboard

yea the next fsb is 124 so its unlikely it will go there. im running it at 850 right now for stability. 995 can be tempermental. sometimes it works and sometimes not. i'd rather not damage the system.

[Mr B]

Fair enough. 850 is still a really good o/c for a C566. Well done.

Doesn't that board have the 1 MHz at a time option in the BIOS?? I thought the BE6 II had the SoftMenu III version.

Yeah, 117 to 124 is one hell of a jump. Too bad you don't have 118 instead of 117 as an option......

Great job, nonetheless.

disabling shadowing makes the vid card (for the most part) do ALL of the work. If you had a VooDoo I'll bet you could disable it and get the extra 5 mhz! [img=http://forums.overclockers.ws/forums/Public/Images/Default/E19.gif]

[ebola]

haha. no i have a viper 550. when i bought it it was top of the line. the only thing as old as my vid card is my motherboard. the bx 6 2 is awesome though. sadly the viper is way outdated. atleast i can still run my resolution at 1200 pixels.

never the less i'm super happy with 850. its sooooooooooooo much faster than my old celly 466 at 584.

Ya gotta love these 566 CBo's. Beleive it or not, ya might get that little extra by using an MSI-6905 Master :)
