too bad your thread states somthing you cant even back up....

You're just too easy.....the fact that the chipset supports 3.0Gbit speeds and is LIMITED to 1.5Gbit BACKS up my thread topic. ;)

Thanks for bumping it with your reply!

So I guess you can't prove your previous statement:

Your quote:

"NCQ show's up but IS NOT ACTIVE"

Was that not on your cert tests?

Until you refute your previous claim with something substantial, you know, like documentation from Apple (kinda like what I did) you will just be dismissed as a butthurt troll! :D

How's that sound?

Here is some more of your unsubstantiated rants.......

that particular chipset was modified by intel for apple, sata II was not included in it for obvious reasons (at the time it was not needed and was at a much higher cost)

this is nothing new

PROVE THIS

yawn...


the ncq shows up as supported...that does not mean its operational.

you put alot of faith into the system profiler and what you read online,

i dont need documentation to backup what im saying you dont believe me then good,

not to mention you act like a 12 year old child, good luck...troll...or whatever name you created for me.

by the way...what is your educational background...besides grade 3 which i can see you have almost completed.
:D

I'm Steve Wozniak.

You must believe me because I say it is so.

Does this argument sound familiar?

I called bull**** on your claim that "NCQ show's up but IS NOT ACTIVE."

My educational background is irrelevant but based on your writing skills and spelling it has clearly surpassed yours.

Making those inquiries about my schooling is just the flapping of a desperate argument anyway.

Again, prove you are right or else your claims are anecdotal at best.

I've posted a couple tech notes and there is documentation all over that refutes your statements.

You are the one that backed yourself into this corner, not me. ;)

wow your a smooth talker,

the fact is...i have all of the repair manuals and documentation at all my disposal...yes i could scan it and show you...but i dont need to...because you r thread is useless...

im better than you....face it
 
The 2008 macbook also had a completely different southbridge controller (intel vs the current nvidia chip) so I don't see how this is relevant.

its not relevant...thats why no one is reading this thread...no one cares

http://en.wikipedia.org/wiki/Native_Command_Queuing

check out how they mention it has to be enabled on both the drive and controller , and how its driver dependent.

wiki isnt the best documentation...but it works for me.

happy now, ncq is supported by leopard. does NOT MEAN ITS ENABLED, its there and its supported but not enabled.

happy now?

Everyone is up in arms about the new model's 1.5Gbit speed cap.

No, not "everyone" is up in arms.

I can understand that some people are upset about this, but the emotional language and exaggeration being displayed in some posts is really not helping.

You post crap with no facts.

You have no credibility.

The only exaggeration is your supposed certified knowledge of the products we are trying to discuss.

Hi

Yes you are correct. The ICH8-M used has SATA 3.0 Gbit/s capability but is capped at 1.5 Gbit/s. There is a reason for that and it affects other laptops as well - Dell, IBM/Lenovo etc

The ICH8-M was incompatible with many SATA-PATA bridge chipsets at the 3.0 Gbit/s level. Since the SATA-PATA bridges were needed due to optical drives being PATA, you'll see this on many laptops. On Desktop motherboards where a separate chipset was used to provide IDE channels and on laptops that had no PATA optical drives, the chipset can and does provide 3.0 Gbit/s

This makes alot of sense to me. I'll give you a scenario.

Say apple was using Sata-Pata bridge chips for the DVD-Rom do to cost of a SATA DVD-rom being to high. then when the Umb came out last fall they found a SATA DVD-rom close to the same price and this allowed SATA2 to be used on the HDD. With the new price cuts they needed to find savings and went back to the Bridge chips in a lower cost DVD-ROM returning the new systems to SATA1 :rolleyes:

Again, WHAT DOES THIS HAVE TO DO WITH LEOPARD?

You are DENSE.

And incorrect!

YOU were the one who claimed the HARDWARE provided by Intel was DESIGNED for Apple WITHOUT those capabilities.

YOU ARE INCORRECT because the CHIPSET does support NCQ (a feature of SATA II) and people have been compiling Linux distros that USE NCQ on that same hardware YOU CLAIM doesn't support it.
 
I have a late 2008 Oct 17" MBP classic with BTO SSD

Its a 2,6 GHz machine. It has the same Intel ICH8-M AHCI the OP states. However the Native Command Queuing shows: No

Is my machine capable of SATA II but is capped? -- My gripe was that I ordered it direct from Applestore BTO with the SSD option. One would expect that SATAII speeds would be enabled for a top of the line machine such as the one I ordered :rolleyes:

Who are you again?

There is a lively debate going on here and you call to close the thread?
 
Wait.. so are you saying that :apple: had not been aware of the issue at hand ? But the first gen MBP's all have 3.0, so obviously, :apple: had knowledge of it before releasing the new MBP's last week. Do you reckon this can be fixed with a firmware update? If so, what's taking so long? :confused:
