Does the INSPIRON 9400 take 2 x 2 GB RAM and which one do you recommend to buy? emoticon.Confused.title
I started using Windows7 and want to virtualize some machines and need more RAM. Currently I go 2 x 1 GB from DELL equipped, but there is no upgrade by DELL to 2 x2 GB, only from KINGSTON:
Hope somebody has experience and allready upgraded his machine and can give me the results.
According to the Owner's Manual for your Inspiron 9400, the maximum supported RAM is 2Gb, which is what you already have. The Intel 945 Chipset doesn't support more than a total of 2Gb, so there is no point to trying to put 2 x 2Gb in to the system. At best the system will only recognise 1Gb from each card, for a total of 2Gb, and at worst the system won't boot up at all. Even if the system did boot up it is likely to give memory errors and be quite unstable, so I would strongly recomend that you don't try it.

I'm using Dell Inspiron 9400 with 4 GB of ram without problem. I have 2 SODIMM of 2 GB each. Indeed, the system sees 4 GB, but uses only 3.25 GB (it mentions the rest is used by BIOS !?!?!)
The system was bought about 4 or 5 years ago, initially with CPU Core Duo @ 1.86, and this year I upgraded it (myself) to Core 2 Duo T7600 @ 2.33 (x64).
I would like to install more ram in it (I plan for 2 SODIMM's of 4 GB each - DDR2), but is anyone who tested this? Will the bios recognize this ram, or not? Normally it should, now being with 64 bit OS. And I wouldn't want to invest in 4 GB sodimm DDR2, which is expensiver then DDR3, and will be useless if the bios won't recognize it. I have the latest bios to date (A10)
The system will recognize all 4G. You may not see all of it though - the chipset reserves certain memory for internal use, and though the chipset in this model does support memory remapping, the BIOS is an older one (the system went end of life long ago, so there will not be any updates) -- so, even with a 64-bit OS you may not see all 4G.
Thanks for answer.
I heard that one has updated the bios of an 9300 with bios for XPS170, to give it a newer one.
Could be possible to update the bios in 9400 with one of some other model that might give him access to more then 4 GB?
I am also considering upgrading from 1meg to 4 mgs of memory in my 9400 XP machine. Dell tells me 4mg isnt supported but can use 800mhz memory now.
Anybody have any knowledge of this? Should I buy 2mgs of pc2-6200 800mhz ram?
Yes i tried running 800mhz RAM in my E1705 and i can tell you the temp went thru the roof.I would not suggest using anything but 667mhz RAM in the E1705.

The reason I ask about the 800mhz ram is that is what Dell tried to sell me twice. Did the ram get hot or somthing else?
I asked them about the 800mhz and they said "yes, we have the software for that now". Since I posted I have heard somewhere that it still runs at 667mhz anyway. Are you a heavy user? Games and so on? Does that make a difference?
The speed of the RAM is governed by the speed of the memory bus. On the I9400 the memory bus speed is 667MHz, so the memory will run at 667MHz. Actually since this is under-clocking the memory it should actually run cooler than it would if it were running at it's native speed of 800MHz, certainly not hotter.
I suspect that dgkpcon was having other problems that caused the over-heating of his system, such as dusty cooling vanes or a defective fan?
As mentioned elsewhere in this topic, if you are running a 32bit version of Windows you will not 'see' all the 4Gb of RAM in Windows. This is due to the limitations of the 32bit architecture of Windows, not a BIOS limitation. How much RAM you actually see in Windows depends on various factors, but it usually is around 3.25GB to 3.5GB. My Dell Vostro 1700 with 4GB RAM showed 3.56Gb RAM in the 32bit version of Windows Vista, while my father's Dell XPS Desktop shows just 3.2Gb RAM in the same OS. I'm now running Windows 7 x64 and have access to the full 4Gb or RAM. Whether you can run a 64bit OS will depend on whether the processor in your system is 64bit capable or not, I suspect not.
