Don't know whether that is true or not.

So they will only have 2 memory slots.

Quite funny of them to blame AMD, the AMD64 technology supports over 128GB of memory, so no problem there.

In reality it's most likely the VIA K8T890 Chipset that's holding back the 2GB limit.

The Nforce3 Go does not support PCI-E. It is an older chipset. And there is no socket 939 Nforce3 Go notebook, all are 754. However it seems that the current nforce4 chipsets are capable of supporting mobile systems
http://www.nvidia.com/page/pg_20041015990644.html
On this page for Nforce4 Ultra there is a section called "Mobility". I wonder if they are really OK for notebooks or not. Will it ever be a Nforce4 Go?

Anyways it is certain that Clevo D900K will use the Via 890 chipset. Both M-Tech and Eurocom are mentioning this on the specification page for their D900K notebooks.

So no nforce4 notebook yet :-(

What's all the hype over 4 gb? Sure, more is often better, but what are you guys doing that actually uses over 2 gbs of RAM? I only have 512 mb right now, and I use all of that sometimes, but I don't think I could use more than 1.5 gigs.

I run a program that maxes out at 1.45 GB with 2GB. It would run a lot faster with 4GB. Everyone who is concerned with having 4GB has a program that they run that slows way down with 2GB. Be glad that you don't need 4GB, those of us who do find our laptop selection very limited.

That is because your applications are designed for Win32 which has a 4 GB limit (2 for OS + 2 for application). If in a few months you switch to Win64 and start using application that take advantage of 64 bit addressing then 2 GB would be totally insufficient. Even if the address registers are 64 bit the Athlon64 CPU has 40 lines for memory addressing. That means it can address 2^40 bytes = 1024 GB, which is more then sufficient for now. So the 2 or 4 GB limit comes from the motherboard not from CPU. I have seen no desktop motherboard for Athlon64 that can use more the 4 GB. My guess is that the motherboard or chipset manufacturers are using only the first 32 of the 40 lines available for memory addressing Only Opteron motherboards can address more the 4 GB

Quite simply? Multitasking (which would be why a number of users purchase a DTR, as not all of us are gamers).

I understand what somebody said about some programs using that much RAM, but trust me, I multi-task plenty, and I still don't think I'd use more than 1.5 gigs if I were doing everything that I'm doing now plus running games in the background. I have 20 IE pages open, 16 AIM windows, several folders open, WMP, WinAMP, mIRC, and Photoshop all running right now and I have 150 mbs to spare. This is on a comp that only has 512 to begin with. If I had 2 gigs, I could have HL2 and Doom3 open in the background, and I still wouldn't be using all the system RAM. At that point the thing that would be slowing me down is my CPU, not lack of 4 gbs of RAM.

I should have likely qualified the previous statement to state "business level multitasking". My apologies.

Also should be noted that none of the above applications mentioned (save perhaps photoshop) are particularly ram intensive.

I've seen Doom 3 suck up a bit more than a gig of RAM. HL2 comes close.

To all who are knowledgeable about AMD cpu's and MB's a couple of Q......

1) Is the MB proposed for the 900K PCIe capable, I assume so????
2) Will it support NCQ like the P4 cpu/MB????
3) What is the max memory speed and is it DDR or DDR 2?? What is the basic difference between the 2???
Thanks.

1) yes
2) probably, not sure
3) the max memory speed is technically 400mhz, but that can be surpassed with overclocking. It would be DDR, not DDR2. DDR2 uses slightly less power and reaches higher clock speeds, but has slower latencies so it and DDR tend to be balanced for overall performance.

I think there will be 2GB SO-DIMMs by early next year if you feel you need more then 2GB you could always upgrade then.

If Clevo stays with the announced VIA K8T890 mainboard chipset, the D900K will not support NCQ. The decision for the VIA chipset has maybe a pricing reason (VIA is cheaper then Nvidia). But I do not understand that move. A high performance DTR notebook like the D900K should have a high performance well equiped mainboard chipset (even if it is more expensive). The nForce4 supports onboard Gigabit Ethernet, onboard hardware firewall, SATA II, NCQ, PCI-E, PowerNow!,...

No... the modeling program that I run was not designed to run on Win32. It runs on 5 different platforms AIX, IRIX, Solaris(Sparc), Linux and Win32. In many cases it will run faster on a PC by virtue of the faster clock speed. It does require some healthy 3d viewers, so graphics is also somewhat important. But not nearly as much as serious gaming.

From all the discussions in this thread and others it is becoming appaent that it is the chipset IMPLEMENTATION that is the most important. All the Centrino stuff is 32 bit so it will never address more than 4GB - Video Ram - other hardware addresses. It seems that no one is even thinking about 4GB even Clevo. It looks like I may be going SFF

From everything I have been reading it will require a new motherboard to acually address it.

It's most likely something to do along the lines nvidia doesn't want their nforce4 (desktop editions) going into laptops, because they also make mobile chipsets, it's just they've been a little slow with the release of the nForce4 Go.

WHAAAAAAAAAAAAT?

No PowerNow/Cool'n'Quiet?!? THAT SUCKS.

In every case (VIA, ATI or Nvidia mainboard chipset) there will be Cool'n'Quiet. All A64 chipsets support that feature now.

All this talk about the cpu...but the 9880 doesnt have cpu heat problems .
That was the 9860. The issue no longer exists.
The heat is from the video card. So if the x800 manages to be cooler during load, you guys are brilliant for waiting.
If not, you still have a shiny new x2 in your laptop
