How would I go about upgrading the RAM on my Latitude D800?

Assuming this HDD doesn't break, I predict I'll get ANOTHER six years from it.

The hard disk thing really has me worried - why do so many fail? Do larger (relatively) drives have higher failure rates now? I've never had even slight issues with the current 30GB one.

 

I'm not sure if recent HDDs fail more frequently than the old ones. Bad news tends to travel faster these days. However, they can fail at any time so have a good backup system in place. In terms of failure based on hours of usage, optical drives are much less reliable.

I left my notebook with a computer place near me, along with the new hdd. It'll cost around $150 for the install, seems like a total rip - but I don't have the gear and software to image my old data onto the new one, c'est la vie. I'll get it back Monday.

 

$140 for labor, and I paid $60 for the new drive, but seeing how much snappier and quick everything is I'd say this was an incredibly solid investment.

More RAM: $100
New HDD: $60
HDD install: $140
total cost upgrading PC so far: $300

and so worth it

 

Hi guys.

I all ready read the entire thread. I also have a Latitude D800.

On March '07 my technisian performs the first upgrade on my laptop installing 2 x 1Gb SoDimm-DDR PC 3200 400MHz and remove the old 2 x 512mb DDR 333MHz that had my OEM Latitude.

I realize today when I made a F2 setup that my current speed memory is 266MHz. Why is that? it is because I have the BIOS A09? or I need to buy DDR PC 2700 333MHz in order to have the maximun performance that support our D800?

And last question? Which brand is better one? (samsung, Kingston, hynix, etc.)

Thanks in advance.

 

Brand doesnt matter as they all perform fairly the same.

Could you run CPU-z and post the screenshots of the Memory & SPD tab?

 

Often the nominally slower RAM also has a lower latency which means the actual throughput is little different.

To check the actual performance, download SiSoftware Sandra and run the memory bandwidth benchmark. One of the built-in benchmark results is for the Intel 855PM chipset and 333MHz RAM.

Hope you can see the numbers.

SPD slot #1 & slot#2 has the same values.

 

@ John Ratsey

Sorry, but I really don´t understand the SiSoftware, it seems confusing to me. I hope I did well & this is the graphic I get it, according your instructions. (Benchmark-Memory Bandwith) But seems that my processor doesn´t appear's. I was clicking here and clicking there and this software get a lot of information that i need to study. I am a newbie and I'm learning from you guys.

Thanks in advance.



P.S. If you another information that you need it, please let me know and I will show it.

 

1. CPU-Z indicates that the RAM can run at up to 400MHz (ie 200MHz x 2).

2. To run the benchmark in Sandra, press the refresh button (to the right of the green arrows - 8th icon - at the bottom of Sandra's screen).
