400 -> 533mhz FSB (dip switch on Z71v)? - Page 3

Okay, I'm really confused. I ordered my laptop from DiscountLaptops, and I ordered the Dothan 1.86ghz processor. That's the fastest it will go with an FID at 14x. However, I opened up the laptop, and the dipswitch is already at 133mhz! :X That is, the tips of the pin are pointing downward towards the "133" that's written on the board. Can this be right???

I'll await a reply before putting it all back together.... but that's really weird.

EDIT: Also, if I underclock it to 100mhz, what will that do? Just out of curiosity? I noticed that the chipset I have is a 750, not a 745... argh. Does this mean I'm out of luck? ;_; Also, the 1.86 I have is clocked at 533mhz by default... I take it there are two different versions?

the dipswitch method will ONLY work if you use an older CPU (Number 7x5, instead of 7x0). You got a newer one, so it cannot be overclocked using this method. I'm not sure what would happen if you underclocked it, but I also don't see a reason why you'd want to, so it's a moot point.

The 1.80 GHz processor is 400MHz FSB. The 1.86 is 533.

Yeah, I didn't realize which version I had until I looked, then it kind of figured itself out for me. >.< Damn... ;_;

Lots of folks haveing success with the dip switch overclocking. Some mentioned moderate temps after the OC. How much increase in temp could I expect if I used a 1.60GHz 400fsb cpu with the switch at 533. I mean, over running the 1.6 stock, with no mods.

Well I just built the Z71V with the same 1.6 chip as yours and I didnt notice it running any hotter. Unless you throw more volts at a cpu it shouldnt raise in temp by maybe an extra 2-3 which is no big deal with these Dothans.

So it may be possible, as someone earlier in the thread said, to undervolt the 1.6 on a 533fsb setting and actually run cooler than stock while running >2.0GHZ?

In regards to the 1.6ghz setting, I think the increase was around 2*C at 2ghz.

And with White Heat's little gizmo he's working on maybe we can eliminate that 2C

His gizmo is for the GPU, not CPU

It is for the GPU - I do have some ideas on helping the CPU run cooler but that will wait...

I updated the thread on the GPU cooler with initial design and some pics of current cooler here

But if heat is removed from the inside of the case will not all components see some benefit

On the Intel 1.7 400FSB I was able to over clock it stable to 2.26 533FSB.

Undervoltage is at min x8 -> I get 0.716

At max x17 -> I get 1.308v

Using Centrino Hardware Control.

I am able to get down to 1.292v stable enough for casual usage. One you play game with it, it get unstable. So 1.308v is perfect safe zone for me.

I have not tried all the multipler between.

As for temperture, as I am typing now on the laptop, it is running at 800 Mhz due to dynamic switch, it is around 39c. The CPU fan is totally OFF.

Battery life as it stand right now is 3.6 hours.

So if you ask me, overclocking rules!

just curious.. is there a reason asus decided not to put the dipswitch in every laptop they make? it would seem that something this awesome would be in everything they sold.

The Z71 notebooks are part of the M7 series, which is a brand new design. The Z70 notebooks are part of the M6 series, which is an update of an earlier model. I'd guess there are certain things you can make on an entirely new model that are harder to do with an update, where there is a certain rigidity on the internal design features.

Just curious, I'm about to get a z71v and do this mod from the start. So I was wondering if there was a step by step guide from hardware to software?

Nope...

All you have to do is plug in the 400FSB Intel Pentium-M

Set the dipswitch on the Z71V accordingly to the documents that make it 533Mhz FSB..BAM...you got overclocked system

smilepak, just curiously... how are you temperatures so low? Even at 800mhz and undervolted, I still run at 50ish temps--and AS5 is applied, of course. What is your secret???

@ 800Mhz it starts off around 38c...and hoover up to 45c on casual usage. If I go max speed, it hoover around 59c - 61c now that I am overclocking....

I've gotten as high as 67c on gaming with it.

I didn't do anything different than a thin layer of AS5 and undervoltage.

I did clean off the heatsink before applying AS5.
