Asus merom support

I called a tech yesterday and they said that the Asus a6j has / will support merom and then i read this : http://www.devhardware.com/forums/cpu-overclocking-19/help-with-oc-a-t2500-core-duo-84634-2.html

post number 21

but now im confused which pins to connect ? Can some please mark the pins for me on a picture of the back side of the proccesor ? Because I fail to understand the diagrams. Please help !

Thanks In Advance

 

To my knowledge, all Asus NAPA based laptops will support Merom.

If you can't figure it out yourself, I would recommend you to stay clear of it.

Here is the link to the Intel® Core™ Duo Processor and Intel® Core™ Solo Processor on 65 nm Process Datasheet (.pdf).

Find the Processor Pinout and Pin list (4.2) and look at table 14 and 15.

 

Interesting, FUGGER over at xtremesystems.org said he just dropped his merom into his NAPA based mac-mini (core duo) and it went off without any issues....

not sure if its different for notebooks....

insane

 

I have no idea why those guys are trying to get their Duo up to 200 MHz FSB relating to Merom. Everything I have read says that Merom for Napa will be 166 MHz FSB like the Duo. I did register and ask in that thread. Merom will only be a 800 (200x4) FSB or 1066 MHZ when Santa Rosa comes out:
http://www.anandtech.com/showdoc.aspx?i=2715&p=2

So in a nut shell dont worry about about it. The merom should be a drop in replacement and the FSB will be the same as the Duo (Yonah). I would watch that thread to see what there answer is to me, I might be wrong.

 

Also dont' worry about it now, since you know all yonah laptops will support Merom when MErom actually releases... August, unless delays. Your not gonna be the frst one to make a change.

Wait till someone else does it and then follow with guidance. Prolly anandtech will have it done or something.

But we will still need ASUS to provide us with a BIOS update right?

No bios update needed as far as I am aware.

They already had a Merom in a Fujitsu N Calistoga notebook over at Xtremesystems.org and it worked fine.

 

Great news!

 

Does this mean that if I were to buy an Asus S96J right now, I would be able to drop in a Merom when it comes out, and it would work fine?

 

that's the gist of it

 

Wow pressure interesting. So the chipset just understands its a 64 bit cpu, and it enable the 64 bit processing right when you place Merom into the chipset?

Interesting.

Can anyone find any info in regards to increasing batterylife?

Thanks,

i haven't seen any indication that the 64-bit capability works....just that there is an increase in performance. i feel like 64-bit would need a bios to enable. can anyone verify?

 

lol, this is one big puzzle! LOL

When you drop Merom into Yonah spot:

1) ~20% Boost Performance: YES
2) ~20% Boost Batterylife: ?? I guess not much
3) Will 64bit work right away: ??
4) Do we need a bios upgrade: ?? Pressure so far say NO.

Well these are some things we need to know =\

Thanks,

MysticGolem

 

i recall reading somewhere for intel's introduction of the merom that there isnt a battery life difference. fyi

 

your right mysticgolem it is one big puzzle.

to think that only the os is responsible for controling these changes. unless current bios is just being limited by having yonah in there.

 

lol when i first heard about Merom, they said, boost performance and batterylife, with 64bit processing.

Now the more recent info doesn't say anything in regards to batterylife.

Also i guess no one has really tested. Also we don't know the power consumption of Merom. 25-55watts....i forget but how much does Yonah and Pent-M use?

Thanks,

MysticGolem

 

So what are people's hunches about running Merom (64-bit) in a laptop that comes with a Yonah chip? I'm considering do this with a S96J... do you think there will be a good chance that it will work?

 

well, for performance increases, it has been verified to work, but we are unsure about the 64-bit. either way, people, especially those considering waiting, should realize that the full potential of merom will not be realized until it is in its the new chipset (santa rosa?).

 

1) Higher performance, yes
2) Merom has a higher Thermal Design Power compared to Yonah. Yonah 31W, Merom below 35W. Unless Merom has better power saving functions, it will give equal or less battery life compared to Yonah on the same platform.
3) The chipset has really not much to do with 64-bit capabilities. Merom is a 64-bit capable chip.
4) ...

 

i was speaking specifically about the performance when i meant full potential. mainly the faster bus speed and larger l2 cache. i am surprised there haven't been anyone testing the 64-bit capabilities of merom....although the increase in performance is nice, i think it's main selling point for me (i will have my notebook for 4+ years) would be 64-bit.

 

Thats an interesting question indeed as Intel dont give out exact TDPs of their processors, Intel's TDP is quoted at 75% of the MAX CPU usage and doesnt include the TDP of the northbridge memory controller. AMD quote 100% CPU usage when giving TDP numbers. and obviouslt inculdes the momory controller.

P-m 533fsb was around 31
P-m 400fsb was around 27

the Yonah 'T' class are between 25 and 50Watts.
Yonah 'L' class are between 14 and 24watts.
and 'U' with a max of 17watts.

http://www.theinquirer.net/?article=25623
seems to think merom will have a TDP of 35Watts.

As for testing the 64bit capabilities of Merom,.... Well I've put WinXP 64bit ed on my lappy and I wasnt too impressed, poor driver support and no real speed boost. I think 64bit tech is only really helpfull to servers at the moment so they can address > 32GB of ram.


Insane

 

Insane, thanks so much for the reply! Sounds like it should be a while before we really need 64-bit.

Unified architecture. Will allow integration to all supporting chipsets

 

The Santa Rosa chipset is the one that isn't going to be out until 2007 though, right?

 

yup....hence spoken to those who are willing to wait

 

that's right.
