D900C or D901C?

I am having trouble determining whether or not my SAGER computer is a Clevo D900C or a D901C.

After doing start->run->dxiag my computer shows the model as D900C.

However, I have a quad-core processor. I am under the impression that the D900C does not support Quad-Core and that the D901C was the first Sager notebook with the power to handle quad-core. Additionally, when looking beneath my computer, I see D901C listed.

Why would dxiag show D900C while all other signs indicate that I had a D901C? The only reason I am asking is because I'm looking to upgrade a few things and need to know whether or not the different model number will have an impact.

1. I want to upgrade from 2gb to 4gb RAM. Do both machines require the exact same RAM or do I need to make absolutely sure which model I have before making my purchase?

2. Is it possible to add a 2nd hard drive to either machine? My current HD is full and I'd love to add another one if possible. Does the model number come in to play here at all?

Thanks for any assistance you might be able to provide.

 

can someone explain the difference between d900f and d901f,too?

 

D900C is blue, D901C is black. That is the only difference. If you look at the clevo guide it tells you how to decipher the model numbers.
The difference between the Sager 9260, 9261 & 9262 is that they are different revisions of the D90xC that support different processors, the only way to tell which you have is to take the bottom cover off and look for the motherboard version (usually on a sticker on one of the RAM slots).

D900F is D900F, D901F does not exist.

Yes dxdiag does that with my D901C as well. A sticker on the bottom of my system tells me that I do have a D901C and yes it allows me to run a Q9650 quad.

Your system can hold three hard disk drives, one underneath the battery and two more right under your touchpad. You can upgrade to 4GB for only a few bucks, check the requirements and make sure you have equal sticks.

 

I think that that's just notebookcheck calling it that because of the D901C, find me anywhere else that calls it D901F (especially on the clevo website) and I might believe you.

 

Thanks Theriko

Thanks for your help. I purchased 4GB of ram yesterday, so that should arrive shortly. I am excited to hear that my system can hold 3 hard disks. Currently, all I have is a single 100GB harddrive because I'm an idiot and thought that I would never fill it up in a million years, but that was before I was introduced to 20gb video games and the horrors of postgresql.

If I were to open my computer, I would likely find 2 empty hard drive locations, right? I don't want to lose or have to re-install any of the things I currently have on this hard drive.

Yes that's the best thing to do!

If you have some experience with replacing parts in laptops you could take the following steps:

- shut down and unplug all cables from your your laptop
- place your laptop upside down and remove the battery by loosening the three screws of the module with the "Caution" sticker. You will probably find your one and only hard disk here.
- now remove the module right underneath the touchpad, by removing four screws. This will reveal a bracket that can contain two more hard disks.
- it is your decision how many and what kind of disks you are going to put in!

Good luck!

 

Thanks so much for your help guys. After doing some research, I've opted to go with the

Western Digital Scorpio Black WD3200BEKT 320GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive

Newegg lists this is a "bare" drive. The drive containing all the cables is $10 more, but the bare drive has like 1,000 positive reviews and the complete drive has only 1 review (and it's negative). Why are so many people purchasing the bare drive? Do they happen to have spare cables laying around or do most computers not require them? I'm clearly a tech noob, so before I go and open up my comp, if anybody knows the answer to this, I would definitely appreciate it. Thanks again for all your help.

 

Seems a fine drive to me and yes you can just plug it in without any cables because the bracket holds a SATA connector.

 

One last question. I purchased 4gb memory from the Crucial website yesterday and received the shipment confirmation email today. I followed the Crucial recommendations for the type of RAM I purchased and made the stupid mistake of not doing some research on my own until after placing the order. I was shocked to see that I had purchased DDR2-667 ram when I can see that my system is currently running DDR2-800. I called up Crucial and they explained to me that they hadn't updated their D900C RAM recommendations since May 2007 and they were not aware that my machine could support 800mhz memory (although it clearly says that it can in the Manual).

Am I correct in making the decision to return the 667 RAM in exchange for 800? I convinced them to pay for the return shipping, but I just wanted to make sure that I'd see a difference between 667 and 800 before going through the hassle.

 

In general (though not always) if the system does not support a specific freuency for the ram it will automatically declock it to the proper speed. The difference between is so small that I would never go for the 667. In practice propably the ram ( both 67 and 800) are so fast that I do not think there is any difference between them. This is becuase the proceessor is not able to proccess so much data that will have to wait for the ram.

But anyway having faster ram will not make things worse.
