Current Official C90s specs

The website specifically says the Core 2 Extreme cannot be overclocked on the C90S, since anything past 2.93GHz makes th esystem unstable, but realize it will be at that speed even while you're not plugged in and overclocking. I don't knwo if it's worth that much, though.

 

All the processors can be overclocked a good amount past 2.93 ghz.

 

YHELOTHAR. I actually have a 945 chipset a 64bit C2D and installed Vista 64-bit and have 4GB of physical installed and the OS only reports 3GB.

Why? Because the 4GB supported includes all the system's memory including video and anything else the manufacturer has utilized it for.

You need to understand what you're reading. The fact is that you will not get 4GB of useable memory with anything based on a 32-bit chipset.

 

So your saying the 945g is 32bit and unable to use 4gb of ram??? That would be wrong. I can point you to several motherboards that fully support 4gb of ram on this chipset. Its a matter that the bios needs to have the option to remap the memory for system use and free it up so that windows can see/use the entire amount.

I have explaned all of this in great detail but it may have been in a different thread. So I will just assume it was and you have not read it.

And whether or not 945G itself can support more than 3GB of RAM I don't know, but here's what ASUS says:

So far none of the 945g asus notebooks have/can. They have not done what needs to be done to let it due so. Probably because they want to "play it safe" memory remaping can cause issues with certian hardware/software because they are hardcoded to read the memory adresses that are normally reserved for the system.

However remaping those addy's will cause errors/issues. Then there is the idea that 4gb of ram in a notebook will not really show much if any inprovement over 3gb because you wont be running nearly the same high resolution/settings you would on a desktop that can tax a system enough to need the extra ram.

It was not a bad move per say, but I think atleast with the c90 they should have the option since its a DTR type.

It may very well be the first that will support 4gb but I highly doubt it, then again sombody may hack the bios and get it to work without offical asus support.

 

:O WHAT!?!?! If this is true then bye bye, Sager 2090!

 

That is... very doubtful. Screw all info on that page.

 

No it can be overclocked past 2.93 ghz unless Asus has put restrictions on the comp which can be modded. 2.93 ghz is just Asus's predetermined max potential since they dont want extreme wear and tear on the laptop leading to complications and hardware failures and such so they determine that a %20 is a good amount over overclocking that is also good to advertise to the public and media. Granted that this is a laptop and thus further thermal restrictions I think 3.2 ghz is possible with 3.4-3.5 being a stretch (which desktops can easily go to.) Asus figures 2.93 is the best amount performance, stability, energy consumption, heat, and overall longevity of the cpu and overall hardware.

 

The program should do an auto 20% max OC up to 2.93ghz. Its probably not adjustable or configurable because they dont want you to break your notebook. however for those really intrested in doing so I am sure there can be a hack/mod made so that you can control the OC.

However 2.93ghz is already way more than enough.

 

As I said, it can use 4GB of RAM but that RAM is TOTAL ram not just system ram. That's why 945 isn't capable of memory remapping. Do you know of any mobile 945 chipset that has this feature?

This Microsoft KB article lists the chipsets required to have 4GB of useable memory in the OS and 945 is NOT listed.

http://support.microsoft.com/kb/929605

And you can't offer me one example of it working, can you?

 

Sure, I never said moble even once tho I said 945G wich is also used in desktops.

4gb native 945g

I can list off dozens of them, 945g is 945g... they just have not given us the option in a notebook that I know of, but the chipset is the same thru and thru.

Alot of documentation

Its much more simple if the chipset can address more than 4gb of memory because new addresses can be handed out above the 4gb line, but there are still ways to make it work with chipsets like the 945g via emulation.

edit: the 945g does only "offically" support up to 4gb of address space thus remaping of the addys above 4gb to see all 4 is not possible by normal means. If you google around tho looks like there are ways, but do so at your own risk

Looks like 945g has alot of negative publicity during my searches, people suing for false advertisment. Alot of companes (gateway) said it supported 4gb of ram and even sold it that way.

 

Sorry, I thought this site and forum and thread was concerning mobile computing.

 

Na i try to be specific, if you read my post I did say something along the lines of "I dont know of any notebooks that have 4gb working" ect.

However despite that your right even the desktop side doesnt really support 4gb, all the "4gb supported" motherboards are more or less false advertisment. Im not afraid to admit I was wrong.

Then again I wasnt really wrong tho because I never said it supported it outright, I said your bios need to have the memory remaping to have it work, and thats true. Any chipset with more than 4gb of memory adressing can have this option, or if you "hack" the 945 it can work. So I was never actually wrong.

So based on that lets call it a draw

 

Yes, but this mobile computer uses a desktop processor and chipset, regardless of its mobility, so desktop specs apply.

 

And as has been resolved, even desktop 945 chipsets lack this feature. I only made that reference because I thought maybe some desktop manufacturer might have done something custom as I obviously, like most people, have no first hand experience with desktop 945 chipsets because they were deprecated before they hit the shelves.

 

the the 945pm/gm mobile chipsets all support 4gb

only 3gb shows in 32bit windows and 64bit shows all 4

wouldnt this be the same?

 

Hey ... totally noob question please bear with me... which os should I install if a get the C90 a 32 bits or a 64 bit os? I can get either but would like toknow if I get any benefits form installing either/

 

64 bit is technically more secure, but most things are best optimized for 32bit. I myself am going with vista ultimate 64

 

will there be any difference with the hardware??? (as in will the C90 hardware run better on one of them or does it even matter?)

 

well right now 32 has better driver optimization so it will run better on that, but the difference should be almost negligent if you don't look for them specifically...
Additionally, 32bit is capped at ~3GB RAM

 

This page wasn't filled out this morning. It looks the most accurate for all the specs to me.

They also sell the "ASUS NVIDIA 8600 512MB Video Card for C90S Notebook ( MXM II v2.0 )", but it doesn't have specs listed yet. I want to know if it's GDDR2 or GDDR3.

 

Its Gddr3. Ken from gentech has confirmed that.

 

Horray! It's the first 512mb GDDR3 8600M GT I know of.

 

If you want to know if you should use 32bit or 64bit just read my review I will be using both and benchmarking it to show the performance difference.

If there is some sort of performance boost 64bit may be worth it even without 4gb of ram, if there isnt then 32bit is the way to go.

Keep in mind some programs are encoded to run in 64bit mode and they generally are faster than the 32 bit versions and you must have a 64bit OS to do that.

 

So now it's GDDR3?! Ok, when I asked for a straight answer on this, I was told DDR2, which supposedly came from Asus....now I'm hearing GDDR3? Alex, would you like to elaborate.

 

why are you so worried about gddr3? you should be asking about the memory clock speeds.

 

GDDR2 and GDDR3 are based on DDR2

 

I'm just curious as to which one it is. It doesn't effect my purchasing decisions at all, I'm just curious to see which it turns out to be since we've heard both back and forth. And both have "confirmed"

 

Ken is reliable and I trust him and he is a reseller who directly interacts with Asus. Also ddr3 does have a signifigant advantage over ddr2 while its not HUGE its still significant. It handles power and heat more efficiently allowing overall more energy to be used without producing much more heat (thus great overclocking) and still good for normal stock speeds since it keeps the heat down and uses energy more efficiently then ddr2. Also it has a higher bandwith because it churns out more bits per clock cycle then ddr2.

 

Well, two weeks ago the product rep "confirmed" DDR2. Now he is "confirming" GDDR3. I don't know which is right. I am leaning towards DDR2, because I am pretty sure the two variants of the 8600M GT are 256 GDDR3 and 512 DDR2. Since this is the first time I have ever heard of 512 GDDR3 being "confirmed" after DDR2 was personally "confirmed" to me, I naturally still believe it will be DDR2.

 

hey i got a question: i noticed that asus only will allow their program to overclock to a max of 2.93ghz and 1279mhz fsb

but it sais that the 2.93ghz cpu (x6800) cannot be overclocked with their program, since it will be unstable

so wouldnt getting the e6700 and overclocking it to 2.93 and 1279 be better then the x6800? (because the x6800 would stay at 1066mhz fsb)

also does the tdp stay the same with overclocking because in that case - the x6800 is 95w compared to the e6700 is 65w which is better battery life and if it stays that way even when overclocking, then saves battery too

or are there other programs that will allow for overclocking on the x6800? dont know much about overclocking....

 

Everything else equal, the E6700 OC'd would be faster. However, the X series processors have a few powerful features which set them apart. The most important (to me) is a feature that allows it to filter out single threaded applications and run them through only one core that is massively overclocked.

 

hmm i'm just wondering if the x6800 will be overclockable without problems

if it isn't, then the e6700 is a much better buy because ti can be overclocked and be faster then the x6800 and is MUCH cheaper. (atleast 300 cheaper)

but is there programs that can overclock a cpu? because i know asus's program won't oc the x6800, but will another program?

and im still wondering about the tdp - does it change when being overclocked or does it stay the same and you even get better battery life (less heat) when overclocking the e6700 compared to the x6800 not oc'd
