OverClock Celeron 850MHz

[wj]

I've over clocked my celeron 566MHz to 850MHz at 1.65 volts. Boot in to windows and all, but lock up in Quake III. Should I up the voltage to 1.7v or 1.75v. and is 1.75 about the highest I should go. I have a FIC slot one VB-601 M/B with an FIC 370socket to slot one card.

Thanks

go to 1.75. i have mines at that speed. it cant go any higher. 1.85 is the safest you can go

Who said 1.85 is the safest voltage?
You actually can run @ 2 volt with good air cooling.
You need to try to step in 0.05 first, and if still lock up you need to increase it again until stable.
It's different on every CPU, mine run perfectly 1.65 volt @ 876 MHz, or 1.85 @ 976 MHz

strange, I can boot to windows at 850 using default voltage, but 1.6v for stable 850

Hell no! 2.0v is crazy.. u know how much you're shortening your cpu life spand by if you bump the oltage that high?

I'll say 1.85 is about as high as you want to go, 1.9 if you feel good about yourself and dont' mind replacing the chip after 7 months.

It's not strange, all CPU is different, I had tested about 10 celeron 566 and the result is different, I had 2 run 850 @ 1.95 volt and the lowest run 1.6 @ 850, this CPU from different batch, the later the batch the better CPU. The other work 850 with different voltage most of them is 1.7 volt
The 1.95 v CPU from week 19 and the 1.6 CPU froom week 34.
If you guys can get the latest 633 with cC0 stepping you can get around 1 GHz easily, it's already in the market.

The reason I could get so many CPU to test cos I work at computer company.

2 volt is crazy? I don't think so if you have good cooling. Actually I run one CPU @ 2 volt for quite a long time, few months for sure since the first 566 hit the street and work fine until now. REMEMBER good cooling!!!

What are you talking about? You rarely hear of a chip dying from voltage. Its the heat that is caused by the higher voltage. Shortening the life? Stock chips are claimed to have a life of 15-20 years under normal load. So you figure OCing that thing to the limit at max will shorten the life by 10 years. So that gives you 5 years. In 5 years you wont even know what a celeron is. We will be up to 5 ghz by then. I say for 85$, burn the sucker!

 

[soundsation]

you've got the point dude he he he,
I wanna ask you guys, how long you keep your CPU?
the longest CPU I had in my system was 2 celeron 366 @ 550, it stayed on my BP6 for almost 9 months. Most of them gone before 6 months, so I don't really care to burn this $ 85 baby.

for me

566@850 1.7V
566@950 1.8V <-- where I have it at now

I'm running at 850MHz at 1.65v. Even made it though a round of Quake III.
To make sure it stable I guess I need to let Quake III do a time loop. So does some one know how to do this. I did at one time have it wrote down. So if one would tell me how to make QIII loop I would be thankful.

I'm dying to know how much you shorten it's life! Tell us! I'm running at 1.75 and to tell you the truth if she lasts 1 year I'd be happy.

where do you get the cco's at?

 

[soundsation]

I am using stepping cB0 right now, but it's week 34 CPU, thats why I could oc'ing a bit higher.
New stepping cC0 it's hit the market on the small quantity, most of 633 celeron is cC0.
Like I said I work at computer company, I get everything I want from this company and the best part : at distributor price.

How do you know what stepping you have, and what week. I got FPO/BATCH# 0034A320. VERSION # A09451-002 can you tell from this.

[soundsation]

FPO/BATCH# 0034A320 ??? I believe it's Q0 not 00 This CPU is week 34 same as mine, this is cB0 stepping, if you want to know the stepping you need to look at the Intel sheet and look at the 5 last digit production code in your CPU, should be like SL3W7.

Well, I believe you needs to get better cooling for your CPU more than retail heatsinkfan for OC
