core 2 duo conroe E6600

I'm currently building a new pc that will use the new intel core 2 duo processor.

is it reasonable to expect to get gentoo working on the machine once I get the computer up? I was thinking there might be issues because its a new processor. I also noticed that there is separate downloads for amd64 architecture, does gentoo expect to do the same for intel 64 bit?

thanks.

so when downloading an architechure tar.gz file, i should grab the amd64 not the x86? the amd64 should work for EM64T.

thanks.

Hi there,

in about one week I'll get my new Conroe-based system. I've some questions concerning kernel + gcc-optimizations:

CFLAGS:
is -march=nocona OK when running gentoo in 32bit-version?

which setting should I choose when installing a 64bit-gentoo?
also -march=nocona ?!

KERNEL:
will the ENHANCED SPEEDSTEP functionality be supported just by running >=2.6.18 and enabling
[*]Enhanced Speedstep and
[*]Use ACPI tables to decode valid frequency/voltage pairs ?

or will I have to wait until some patches appear on the horizon?

=> is there a chance that the CPU will be damaged when running it on a kernel without specific patches for it ? (<== this question is very important to me since I haven't got that much money and can't afford to buy another if the cpu is fried ...)

Thanks in Advance

Some people at the Xtremesystems Forums are runing these under debian/knoppix already and they say that the core duo 2 is really a beast

Hello all

I just got my new system today. Core 2 duo E6600 and an Asus P5B motherboard.

I am still struggling to find out:

- what safe flags to use

- which processer architecture to download install files for (x86 or AMD64)

- which stage tarballs would be the best in my situation

- any other applicable info (like if there are features in certain kernels that supports conroe better etc.)

Thx in advance. I'll post my finding once I get it up and running. Don't expect too much tho - I'm no expert :-)

As the core duo2 supports 64bit you have to use amd64 stages. I would use stage 3 as the other stages are unsupported since 2005.

A really good question is what -march setting you have to use. maybe someone here knows it already, but i am not sure if "nocona" is the right arch.

You don't need to use the 64bit though. You can still use X86 if you want. You can use either 64 or 32bit.

But the processor its self should work no matter what, just like stated above, you may run into trouble with the chipset for somethings.

Now that we start to see people installing Gentoo on their Core 2 Duo machines it would be nice to have a definite FAQ about how to install a 64-bit system.

1. What CFLAGS to use? Especially is -march=nocona the correct one?
2. What CHOST to use? Is "x86_64-pc-linux-gnu" the one?
3. Which stage3 tarball is the correct? i686 or AMD64? If AMD64, then the stage and keywords should be immediately renamed as they don't reflect the reality.

PS. This might belong to "Installing Gentoo" so please move it if this is the case.

to 3.
actually the name is reflecting reality as Intel copied a design from AMD and gave it a new name to cover up its shame :twisted:

Please, let's not make this a fanboy thread. Copying has been done so many times (by both sides) that this shouldn't make any difference. Gentoo shouldn't favor AMD over Intel or Intel over AMD and this is why I asked. Especially:

4. Is there anything AMD specific in AMD64 stage3 or does is also work with EM64T?
5. Is there anything AMD specific in the keyword amd64 or do the packages also work with EM64T?

maybe I should attach <cynism> </cynism> tags next time

AFAIK besides the processor type in kernel there are no architecture specific settings in the arch. But I am not a developer and have never tested it on an Intel as I have not bought a machine in the last half a year.

AMD64 and EM64T are compatible with each other. The only reason why you should use -march=nocona on a Core 2 is because -march=[k8,opteron,amd64,...] sets the 3Dnow! Cflag, which Intel does not support. See the GCC i386 and x86_64 options manual for more details.
I also hope for all you Core 2 owners that the GCC devs will make a Core2 option, because Nocona is a Pentium 4, which is based on the Netburst architecture.

I am planning a major system upgrade towards the end of the year and I am looking into the Core2 CPU as well as the northbridge being intel's 975X or P965 chipsets

does the present liveCD (I guess 2006.1) kernel support these (mainly the southbridge chips)
ie would I be able to boot and start the install?

Sweet!! my concern really isn't with the actual Core2 CPU (that I beleive is supported) but more with the "glue-chips" it needs ie the northbridge and such which are comming out on Core2 mobo's

As long as there is some method to install I will get it installed, even it if means using a Ubuntu liveCD (to do hte Gentoo install) if they have a new release by the time I decide to upgrade
