Window detects 3.25GB RAM when I installed 4GB

So is there any wai I could run my RAM at 800 mhz?2gb Ram 800mhz RAM or 4GB 667mhz which one is faster?

I did the last debug in a rush but have now had a closer look, my verdict is the same but I am more sure now that it is the drivers for the wireless card. I can only assume as you are using a dongle the PC does not have a built in wireless card so it must be the drivers for the USB dongle.

Qwertymaster, I know this thread is going quite fast but you missed my question in post 17, can we have the full number off the RAM stick label.

Here are the numbers:Simmtronics 2gb ddr2 800mhz
SG10-172606 and SG10-172636

as far my ethernet is concerned there is one called realtek RTL8102e/RTL8103E family PCI-E Ethernet NIC(NDIS 6.20)...

Two different numbers? Is that one on each or are both of those numbers on each stick.

Has it actually got 800MHz written on it somewhere? I got nothing back on searching for those numbers so seem to have reached a dead end.

The only information I got for your Bios was from a later version and it gave no details about RAM voltage settings, although the settings must be there somewhere, you may just have to hunt through the various pages in the set up, probably a section with Power in the name.

Have you replaced the old sticks or are you running them side by side with the old ones as that would make them run at the same speed as the slower sticks.

I am sure your Ethernet is fine the driver in the BSOD definately related to a wireless device.

That's because there isn't actually a "DDR4", at least not yet.

Video graphics RAM has both >G<DDR4 and GDDR5. As I understand it, these are based in DDR3 tech, bit access is (up to?) 256 bits, unlike system RAM which is fixed at 64 bit access.

You're starting to ask the same question over, and expecting a different answer. Regardless of the Windows version, (XP, VIsta, Windows 7), a 32 bit OS can only access, (or allocate if you prefer), 4GB of total memory, with memory addresses subtracted for all the hardware attached to the system. In plain words, that leaves about 3.25 GB of usable RAM

Yes one on each stick.yes they have mentioned 800mhz on the sticker,i have even checked the hologram,matched it with the one in their website it seemed genuine.
I checked my Bios there was this section for voltage setting when i entered there was:

1.ACPI suspend type - S3(STR)
it had another option of S1(pos)but it was set at s3(STR)

2.Remote wake up - on

3.Auto power on - Disabled

4.AC recovery - Off

That looks like the power settings. Even though it's good to see these settings, they are not related to the memory voltage - remember these if you plan on running a Linux OS in the future

You'll have to continue searching for the memory settings. Remember: as I've said, 'tweak' settings are not standard, there is a chance that your BIOS/motherboard does not support a manual change of the voltage.

The MHz is in fact the "speed" - the rate of a read/write cycle unless I'm mistaken. 800 > 667, the 800MHz-stick is faster.

That explains the 800MHz --> 667MHz drop we experienced earlier.
By running a 800MHz-rated stick side-by-side with a 667MHz stick, you are actually decreasing the speed of your memory-system. But keep in mind that the amount of available memory has still gone up.

I just checked the system details on the Dell site and you only have two RAM slots.

As your sticks have different numbers on each that would suggest this is not a matched pair.

Try this experiment.

Put just one of the new sticks into DIMM slot 1 leaving the other slot empty, boot the PC and check in the Bios to see what frequency it shows, power down and swap the sticks over then repeat the process.

I could be wrong but I suspect one will show 800MHz and the other will be 667MHz.

I tested them individually and what I discovered was, individually also they were running at 667mhz
and I called the dealer and asked him to get the sticks changed...though on the sticker its written 800mhz i think they have mistakenly put wrong sticker...I would rather buy Kingston or Transcend stick instead I suppose they don't deceive like this... anyway thank you so much for helping me throughout MARK56.

Your welcome.

yes I ws right problem were the sticks bought kingston sticks working pretty well at 800mhz...

Excellent, you can't go wrong with Kingston.

It will not resolve the problem, if it is XP 32 bit. It will let you use the same amount of memory of 7 32 bit as they suffers the same limitation due to the 32 bit memory management.

I know you are only trying to help but the post is resolved and that point was answered in post 25
