Whats This CHIP exactly?! ... Come Here Hardware Professionals PLZ!

[HamidFULL]

Guys I need to know some information about this chip seems It based on all of motherboards whats this chip?!



Thank you!

[Turrican]

looks like a clock-generator

[massman]

Yeap, what Turrican says

[dinos22]

yup pll chip

[HamidFULL]

Thanks a lot guys but what do a clock-generator chip exactly?

yup pll chip

ppl chip = clock-generator chip?

It regulates the "pulse", the "tick and tock" of the system clock, which everything else on the motherboard uses to determine its speed and when and for how long it does an operation. Without that chip, nothing on your motherboard would work. From this we get the term "overclock" - on the earliest machines, you could change the value that this system clock gave out, and speeding up this value, obviously, made everything else run faster.

great reply! then we Overclock our systems we command this chip to set higher FSB,Mem Freq and etc?

[quake6]

Yes

[HamidFULL]

Yes

tnx! ok then its great and awesome!

model of this chip could effect to Maximum/Stable Overclocking?

How much these chips cost usually?

[cadaveca]

yes, chip affects max FSB, see XBX1 and XBX2 for more insight to this...Fugger made a few comments if I remember correctly...when Core2 first came out...and XBX needed mods...

WOW! and tnx for link! means Fugger replaced this chip!?! how it would be possible its built-in chip for a mobo! interesting ...

PS : How I can find some information about the chip that is in first post which number is exact model?

There are many databases online with detailed pdfs from different manufacturers. Normally you can find a components by typing in (part of the) codes that are written on the IC. Google usually works.

I searched for your components but couldn't find anything. This may be due to the fact that the chip is very new.

ppl chip = clock-generator chip?

The black chip is a pll (phase locked loop). The metallic thing (with an aluminum cover) is a clock generator (crystal oscillator to be more exact.) The pll takes the signal and multiplies/divides it.
For example let's say that the crystal oscillator outputs a 25MHz signal. The pll takes this , multiplies by 4 and divides by 3 and you got 33MHz for the PCI. Also then multiplies it by 10 and you have a 333MHz FSB and so on. It has many pins because it gives a lot of independent signals. If you set PCI lock, the PCi frequency will remain at 33MHz, while for the FSB the multipliers/dividers change in order to set it to whatever you want.
Actually the term pll is kind of wrong. This is a frequency multiplier/divider, which you obtain from a pll plus a filter and a limiter (amplifier in saturation).
I can explain in detail how it works, but you need some electronics and signal processing knowledge.

Awesome!!!! then its phase locked loop not clock generator! my means was black chip not metallic! but now I find out more! tnx a lot

Great! I learned with example!

I'm computer Engineer but seems I had to learn some info about electronics and signal processing any reference just for know more about Motherboards,VGA and similar boards?

Thank you also I googled! but found nothing! anyway tnx

What wiki says?! check here plz : http://en.wikipedia.org/wiki/Clock_generator

it say same as you but not in name of chips!

[DX_Medic]

it's a PLL. Looks to be off an audigy or somethin.

[ownage]

You could try an almost identical IC.



Not exactly the same chip, but from the same line so it might work. I found 2 nearly identical PLL's for my laptop for example.

Wow. I love computers but don't have that kind of indepth knowledge. Thats fascinating. What determines the MHz signal strength for the crystal oscillator? How does the pll multiply and divide the signal? And why does it?

Edit: Wait, I answered my own question with a bit of research. The crystal supplies a frequency by electrical current causing it to vibrate. The faster the current, the more vibration resulting in a change in frequency. The pll uses the frequency as a reference to generate a signal to drive the voltage controlled oscillator for an output frequency to generate a stable frequency used for broadcasting. Simplified explanation but it makes sense. Thanks.

great post

[ownage]

great post

You found a working PPL?

[George_o/c]

Great stuff !

[HamidFULL]

Still I cant find a software for this PLL also in BIOS I cant set PLL voltage ,

PLL voltage option is not available in many of BIOSes and just I found GBT P45 with this option ...
