Hello.

I have an intel e7400 and i want to unlock the multiplier so that i broaden my overclocking. Is it possible ???
I have heard that i can do this by upgrading my bios to a hacked version that allows you to have the multiplier you want.
Can anyone help me ? Am i I right ???Where can i find the hacked bios???

Thanks In Advance.

Don't think you can do that anymore, changing the bus should give you as much as it can do anyway.

Years ago you could short pins to change the multiplier and then years before that you could move jumpers on the board. But some kind engineers have designed the adjustable FSB to make our lives so much easier.

And other unkind engineers locked the internal multiplier of most CPU chips.

my ploblem is that my multiplier is limited .
it can take values from 6 to 10,5.
is there a way to unlock it so it can take any value ???

if you wanted to OC on a budget you should have gotten an amd BE.

Have you tried overclocking the FSB? It's a much more efficient way to overclock as in data bandwidth over CPU frequency. Exactly, how much overclocking progress have you had so far with that e7400 and which motherboard are you using?

^ he said he wanted to get further than just oc'ing the FSB.

Yes , i overclock the FSB. So far , i have overclocked to 3,333 Ghz using bus clock 333 and 10 multiplier.I have an asus p5q se/r , p45 chipset MOBO.

you should be able to get to 3.5-3.6ghz.

i haven't tried more because i am not sure about if the system is going to boot or not.
what do you think ???
will it be able to boot if i have bus clock 333 and 10,5 multilier ???(what means 3,5 Ghz)

*Scratches head*

 

Your trying to unlock your multiplier even tho you havnt maxed it out yet?

 

Not knowing if its going to boot is a reality of overclocking. Try it and see. Worst that can happen is you have to reset your bios.

OK , i maxed it out , it was perfect. it boots alright and the tempreature is not very high .
do you think it can go more ??? i am not sure ....

Try it and see. Every chip is different. We cant tell you how far it and your motherboard will clock. You have to find that out.

^ have you put the voltage up?

no , i haven't tried this ??? does it matter ?? i mean , would it help the cpu to boot @ 3,7 Ghz???

If you still have the voltage on auto, you should take it off of that and set it manually. It is safe to set the voltage as high as about 1.36, possibly 1.4 if you push it a bit. Keep an eye on temperatures as well. Push it as high as you can while staying under 72C or so full load and 1.36 volts.

Not even years ago. With the Q6600 there was a pin (well not really since it has no pins) mod to actually set the FSB to a standard 333MHz thus giving you a stock OC of 3GHz.

There are always some out there. But not all.

the voltage is limited and it's max value is 1,263 so how i am going to set the voltage higher ???

p.s. sorry for my bad english

yesterday i broke my record . 3,6 Ghz , 1600 Fsb and the tempreature was stable.
400 (bus clock) x 9(multiplier) = 3,6 Ghz , 1600 fsb

i'm using the same processor. just pust the voltage at 1.48750. and 400x10= 4Ghz is possible. i'm trying for 4.5 or more. this system is perfectlly stable.http://photos-a.ak.fbcdn.net/hphotos-ak-snc1/hs117.snc1/4975_93618866633_718666633_2098424_3578303_n.jpg

1.48 is a bit high though for a 45nm CPU. It'll work fine short term, but as a long term system, it is likely to slowly damage the CPU due to the high voltage.
