650e cBO not impressed :(

[Buckichiro]

Just unpacked my new 650 cBO and I am a little disappointed. I expected to set this baby up at 150FSB and have it smokin at 975.

So far I am only stable at 910 default voltage and I am loosing my 150FSB I had with the 600e@902

I need to do some more testing in the intermediate ranges to see what it will do.

I think heat is more a problem with this chip than my 600e cBO. Does anyone know a way to get the stock heatsink off without ripping up the four plastic pins?

Anyone with a 650 please let me know what your chips will do and what cooling you are using.

Thanks -Todd

old steppings 650e slot 1

1.65 V to 1.7 v
P3125 with Ice 71 peltier on 12V, around 2 to 7 c @ 936 Mhz.

Can't you just pop those four plastic pin out from the back using a screw?

Look at the heatsink from the orginal P3. It is the exact same as the one that come with the coppermine. If it can handle 2.0v, it can handle kicking the voltage up to maybe 1.75, or, I had mine at 1.8.

Old stepping p3 650, Running at 948, at 1.6 volts. 1 Peltier,( frost 74 ), cpu will do 1012. Water cooled.

I think the 600e"s were generally better than the 650E's?

[Big Lar]

I think so too/ In general that is,... I think we ALL expect the max out of every chip, But I do agreee with TN, I think that near always the Lower Multiplier for a given series of chip, will produce the highest yeild.

Buckichiro:

I just took the cover off of my P3 600E with the cB0 stepping like ten minutes ago and let me tell you it requires a lot more pressure than that article mentions to pop those pins out. I had to bare almost all my weight on it to get them to come out. And you will here a very loud crack. I almost **** my pants because I thought I had broken the thing in half. But all should be ok. So be prepared to use lots of force and hear a loud cracking sound.

Yup... Tha articles kinda forget to mention that, but it is normal... It takes quite the amount of pressure to "press" the pins out.......

The cool thing is if you want to RMA it you can put retail HS/F back on... or at least I did with the help of a hammer to get the pins back in. And yes, I went numb when I heard those loud cracking sounds. I thought I shattered the chip. After all, I put all of my weight on it.

Well I am a little happier now. I removed the cover and put on my global win VS504 and am running at 930 air cooled stable at 1.7v. Idle temps are 25c as compared to 38c. I am going to let it burn in a little here then up it a little bit and see what it will do. It will run at 975 but is really flaky. I don't know if voltage will help we'll see.

Thanks for all the replies....I read them a little too late and already cut the pins on the inside to get it off. Luckily, I have another retail if anything goes wrong I can just use it.

I don't know how much the Intel specs mean to you, but the recommended voltage range for coppermines is 1.58-1.68v if I'm not mistaken. Is it really wise to push beyond 1.7v? 1.8v?!

[Maxout]

If we wanted to run within the specs we wouldn't be here!

Overclocking is obviously not in specs... The question was regarding voltage.

I guess the reason I ask Maxout is because I thought that the processor might be a bit more sensitive to voltage then just simply being overclocked, know what I mean?
