Dell computer with intel 440BX chipset

[Mildlyamused]

I've got a dell computer with an intel motherboard, integrated graphics on the intel 440bx chipset. I have 1 256MB PC 100 memory stick CL2 and when I run si-soft sandra, I get a memory score of only 275MB/s 35% bandwidth efficiency. I've got another system with this chipset and it gets a bandwidth efficiency of 90%! So I have no idea whats going on, I've got the latest bios revision.

I don't see how a northbridge memory controller could ever get 90% efficiency. That doesn't sound right any more than 35% efficiency. Make sure the PC 100 memory stick isn't running at 66 or even 33 for some reason, like a jumper.

Could the integrated graphics be holding back the memory? That doesn't make sense.

The system with 90% bandwidth efficiency is very speedy while the system with 30% bandwidth efficiency is not so.

What CPU do you have in that system, and what CPU do you have in the other one..

re-run the tests. Make sure you're using the same software on both computers to run the tests.

Ok the system specs go like this:
1 256MB stick
2 128MB sticks
PIII 1GHZ Processor
Intel 440BX chipset
One system is a dell v333c slot 1 originally had a 333MHZ celeron

Second system is an Dimension XPS R450 originally had a PII 450 slot 1 with same software etc..
Same Memory used in first test system
Same processor used in first test system
Same chipset, 440BX.

First system has 53% integer efficiency ALU
Second system has a 90% integer efficiency ALU
First system has 73% FPU efficiency
Second system has 90% FPU efficiency
?

Seriously I can't see how 440BX had integrated graphics version available, at least to my knowledge, it must have been called something else, not 440BX.

On those old integrated graphics motherboards, the video is integrated onto the motherboard not into the chipset. Usually they have an ATI rage chip and 4MB or 8MB of SGRAM. It's not a UMA solution.

How much of the total memory is dedicated to the onboard video (BIOS should tell you)?

Did you try one DIMM at a time? Not all brands of RAM play well together.
