Problem installing new 1GB DDR RAM into Dell Latitude D800 laptop

Hello,

I just installed 1GB of DDR RAM into my Dell Latitude D800 laptop, but when I try to turn it on afterwards the area on the keyboard with the 3 lights representing Num Lock, Caps Lock, and Scroll Lock simply blink, specifically the Caps Lock light, and after a few seconds of that the computer turns itself off again.

I even tried putting in the two 256MB RAM sticks originally in there back in there again to make sure it turns on if the original two are put back in there and it does. But every time I try to turn it on with the new 1GB RAM stick it just blinks and doesn't turn on.

The RAM stick is definitely right for the system. I only purchased it after hours of research to make sure it's the right one, especially by using the www.crucial.com scan, and purchased it brand new specifically from a reputable seller listing the RAM as specifically for the D800 (my exact laptop).

Everything looks legit, including the way I put it in, which is very easy, as it clicks completely into place, so I don't see how I could possibly mess that part up. Everything looks good except for the laptop not turning on.

Technical details: The laptop originally had two 256MB sticks in it, labeled PC2100 266MHz, while the new 1GB stick is labeled DDR-1 333MHz. (research showed for a fact that PC2700 sticks work in the D800) The laptop never turns on with the new 1GB stick installed, whether I install it by itself with no other stick or mixed with one of the two PC2100 sticks.

I don't want to put words into anyone's mouth as I am not an expert in RAM, I only want to say that guesses I have wondered about, for instance, are: Do I need another 1GB RAM stick next to this 1GB RAM stick for this to work? Or, do I need to update the laptop's BIOS before it can detect 1GB of RAM or PC2700 RAM?

Thank you

I tried it with every combination possible:
256MB + 256MB = works
256MB + Empty = works
256MB + 1GB = fails
1GB + Empty = fails

Can I have your Service Tag of your laptop and your link to your ram that you order.

Sounds like different timings

It is not a good idea to provide that information off the Dell site where you check for hardware upgrades etc.

That said, check what version BIOS you have. It may be that you need to update the BIOS in order for the computer to recognize the new RAM.

Oh okay, I provided it because I was asked, but I'll do the BIOS check now. Thanks

new 1GB stick is labeled DDR-1 333MHz

The DDR RAM stick specified will run only at 266 Mhz (PC 2100) according to this PDF link

Oh no! I successfully installed the latest BIOS (It went from A02 to A13) off the Dell site, but unfortunately the RAM problem persists.

OP: I would say that memory module is the wrong frequency that can cause that issue Also DIMM_1 has to be fill to boot the computer. From other resources I gather that could be the wrong type of ram that you order was the wrong type.

http://www2.corsair.com/configurator/system_results.aspx?sc=us&id=168891

Bios updated wouldn't render a standard memory change out

Sorry for that moderators. I was only looking at specifications of the memory module. that required a service tag but sorry that was a mistake. I should have look at other ways
Again I am sorry for the mistake

Dell can be persnickety about which RAM it accepts. If it's not Dell branded, it might not work. That isn't always the case, but I have seen several reports of that happening. Last year, I tried to upgrade the RAM on my computer, and it didn't work. Everything I researched says that it should have. Only thing was, it wasn't Dell branded.

So this year, I went to the Dell site to find out which RAM upgrades they recommended for my system using the service tag method. I copied the manufacturer part number then searched for the best price for that specific part number making sure I was getting a reputable seller. That RAM works like a charm. I installed it just a few days ago.

Hmm I don't mean to be naive, I just don't expect a reputable RAM seller to mention my exact laptop model D800 unless it definitely works for it. I contacted the seller and am awaiting their response. It sounds like the best move now would be to get a Dell brand 1GB stick, but should I be sure to go with PC2100 or would PC2700 definitely work if that's cheaper, because of backwards compatibility? Thank you

Dell lists that speed as a possible RAM upgrade for this model computer.

Hi andrewset,

My name is Saurabh.

I understand the inconvenience that you may be facing due to the upgraded memory not working in the system. Would be glad to assist.

Please mention the exact technical specification of the memory cards that you have purchased. I need to know if it is synchronous, non-synchronous, ECC, non-ECC.
I would appreciate if you could mention an online link for the card that you have purchased.

Also find mentioned below, the standard technical specs of a 1GB memory card recommended for an upgrade for your system:

Package Type: 200-pin
Logical Type: SDRAM-DDR 333MHz Unbuffered SODIMM Non-ECC
Speed: 333MHz Description 1GB MODULE
Data Integrity Check Non-ECC
Technology SDRAM-DDR

Dell branded or non-Dell branded, if the memory card meets these specifications, it should work with your computer. As requested, please mention the exact specs of the card installed.

Thanks & Regards
Saurabh_A
