Does anybod know which Intel CPU in the 630 and above series have their multipliers unlocked.
thanks for the help
 
ES means Engineering Sample. They are NOT available for purchase. They are property of intel and are illegal to own and use unless you are an intel engineer. Intel sends these chips out to companies before the locked ones hit stores so companies can test them on their products. Some of these 'ES' chips hit the used market like for sale forums or ebay because those companies have employees that sell the chips. It is very rare to come across them but they do exist.
 
yeah, you wont find one in any store, and i highly doubt youll get one on ebay. whenever they DO show up on ebay, intel steps in and demands return of the chip to them.
 
I was hoping they would relase chip like the 550 and up where you could change the multiplier to 14 then adjust the clock speed I had my old 550 overclocked to 3.9.
kinda miss it
 
That thread got only one reply so I thought I would ask again
Try to get an answer from someone else.
 
ok you're not really understanding the "unlocked" / "locked" multiplier thing are you?

All 6xx series have unlocked LOWER multipliers, (with the correct motherboard/ BIOS). And I believe all the 5x1's (and/or the 5xxj's) all have unlocked lower multipliers. The lower multipliers allow the CPU to throttle down to 14x (2.8Ghz) when not being used. This also lets you maximize the FSB by lowering your multiplier and seeing how high you can OC the FSB/memory for maximum performance. Then you can also raise the multiplier back up towards the defaults once you found the max FSB OC.

On the 840 Extreme Edition, they have unlocked multipliers upwards so you can overclock with out adjusting the FSB or do almost whatever clockspeed / FSB you want. (with in hardware limits)

630 you have 14 or 15 available
640 you have 14-16 available
650 14-17
660 14-18
670 14-19

One problem though, if you lower your multiplier to 14x and overclock from there your CPU can't throttle at all. But if you leave your multiplier alone on say a 650 and you overclock up to 4Ghz (235FSB), when your CPU isn't being used it can throttle back to 14x multiplier (235x14=3.3Ghz) and run cooler and use less electricity, etc.. assuming you set up the power management thing on windows.
 
I have the bios that allows it on my board it shows in the manual the option in the BIOS to change it manualy I have the latest BIOS. their CPU is a 640 mine is a 630.I understand it.What I don't understand is why it is not showing up for me and ASUS refuses to help. But they do say it it is there. They say it should be the same setup as my 550 14x280 = 3.92
they cant tell me which CPU's because Intel will get mad at them. ASUS said I need an uncapped CPU.

WTF, are you all talking about.

Maybe they mean unlocked upward CPU (ES) by "uncapped". (cap = top = upper limit)

When talking to people you should talk to them about the EIST / speed step for lowering the multiplier.

If you ask them about overclocking & multipliers in the same sentence, they assume you want to overclock via the multiplier like with an 840 Extreme Edition or another chip thats an unlocked Engineering Sample.

I believe you need to enable the Enhanced Speed Step option in the BIOS before it allows you to lower multiplier. Someone correct me if I'm wrong b/c I don't have a recent Asus board.
 
maybe theyre talking about a mobile?

not sure if mobile prescotts are uncapped or not...
