overclocking a celeron 566

[beaglesrule]

i am a newbie to overclocking and have some basic
questions - i'm hoping that you good folks can help me out.

i'm running a celeron 566 in an abit vh6 motherboard, with a golden orb sitting on top of the cpu and several fans. my video card is a voodoo5500 agp, and i've got a soundblaster mp3/5.1 sound card. for memory i've got 3 sticks of 128/133.

i am trying to overclock by setting the fsb to 100 (to
bring the cpu to 850). the max voltage i can get is
1.7v (the bios settings won't go higher). when i do
this, some of my software runs fine (internet, quicken,
etc), but games like mm2 and unreal tournament
lock up on me. by this i mean all input devices -
joystick, mouse, keyboard - stop working, although
the game seems to keep playing by itself.

any help here would be appreciated. i'd love to
be running at 850, but until i can get this resolved
i'm moping along at 566........

First I think ya need to find a way to bump up the voltage. Of course when ya do that (IMHO) ya need to lose the Orb and get a good OC'ing type cooler. Gorbs are fine for stock speeds and lite OC but not up to the task when yer pushin' things. If ya can goose'er and give'er what she needs, that lil' Celly will dance for ya :)

You might want to get rid of the gorb anyway, as a really good cpu cooling solution might allow the 850 you want without any more modification. Alpha's and Global Win's are the most recomended here, although there are new generation h.s. setups coming out. The gorb is probably one of the single most sucessfull marketing gimmicks to come along in a long time...everybody wants one....I personaly think it's the "Gold" in golden orb that makes it attractive..that and it just looks cool, but looks are secondary to hardcore hardware people who hang here...(at least that's the way I am)...I must confess, I own one too, and it sits on a PIII 600E @ 840mhz 24/7.
This 600E had a alpha P3-125 on it and was @ 956, so I know the gorb is adequate for the mild overclock of my 600E

For what you want to do, the Golden Orb is fine.

Alot of these PIII overclockers and almost ANY AMD guys will tell you the Gorb is junk. Well, it is, but it is fine for running a Celeron, they dont produce that much heat. Especially @ "only" 850.

I was running a Celeron 566 @ 952Mhz (112fsb) with 1.55v (almost default!) and was only using a Golden Orb. It would run 100fsb (850) at default voltage no problem. I was using an ASUS Smartslot converter card (recomend quality c-card).

Of course because of the extreamly low voltage I was running, it was running cooler then stock temps.

The only extra case cooling I had was a Slot cooler under my tnt2 ultra.

I was running an AX6BC MB and 128mb APacer Ram (ran 112 cas2 fine).

Obviously my results were not normal. You definatly need more voltage then 1.7! I would not go above 1.90v with the GoldenOrb (assuming you have case fans) and in my paticular case, anything over 1.80 made me nervous, but I would have run it at 1.85v if I had to to get 952.

BTW The chip was a 1000+ chip, but my MB only had a 112fsb or 133, so I was stuck @ 952.

3dmark2000 scores with Tnt2 Ultra:
@566 - 2385
@850 - 3273
@952 - 3818

It is DEFINATLY worth it to do what you gotta do to get to 850... the boost in fsb from 66 to 100 is great.

One thing I had to do to get 850+ to run stable was change the AGP jumper on my motherboard. I had to change it from "Default" to "2/3" ... try that, might just be your videocard killing you...

If I had not changed that 1 little jumper, I would have been running 708 instead of 952... woowee, am I glad I found that jumper :-)

Good luck! Hope I helped out.

Do you have a 75 FSB choice, or do you only have 66 and 100 MHz settings? Two things to try in order to reach the magical 850 mark. First, take the Gorb off, scrape that crappy thermal tape off and use some good thermal paste. Consider lapping the heatsink, that helped when I was using a Gorb. Then if all your RAM SIMM slots are full, try removing one module, so you have an empty slot, then try overclocking again. If you still are unstable, then you need a little more voltage. I bet 1.75v or 1.8v would work fine and the Gorb should handle that ok, if you are using good thermal paste (Radio Shack has pretty good paste if you're on a budget). If you go over 850 and more than 1.8v, you better invest in a better cooler. So, how do you get more voltage? Use the "wire trick" to increase the default voltage. Go to the URL listed below. I have done this and it works. Email me for more details.
