Let's go round in circles, shall we? There were later 8200 units that
shipped with the Intel 850E chipset. That chipset (with proper BIOS
accomodation) did support PC1066 RIMMs.

Same chipset as was in the later 8250 model - the BIOS being the only
apparent obstacle in those latter 8200 systems.

My question - to Tim - was if his posted information was a result of PC800
or PC1066 RIMMs installed along with his 533mhz FSB CPU.

You are correct. 8200's prior to about June 2002 when Intel released the
2.53Ghz processor, had the standard 850 chipset.

With the introduction of the 2.53Ghz processor that ran at the new 533Mhz
FSB, the 8200's came with the 850E chipset.

Soon thereafter, Intel announced support for the PC1066 RDRAM, however, the
Dell 8200's BIOS did NOT support the PC1066 RDRAMS.

Other manufacturer's DID start supporting PC1066, but Dell never did. Not in
the 8200 even tho the newer ones had the necessary 850E chipset.

In my case, my 8200 came with PC800-40 RDRAM

Putting PC1066 RDRAM in it wouldn't change a thing. the memory would still
be limited by the BIOS and run at the same 400Mhz channel speed.

I believe there were rumors back then of people flashing their Dells with an
Intel bios at their own risk in hopes of being able to utilize the PC1066,
but I don't think many were successful.

That's when Dell released the Dimension 8250.


I would venture to guess that the difference in overall system speed on a
day to day basis running regular office type apps, that you would be hard
pressed to tell the difference between PC800 and PC1066 memory. In
benchmarks and some apps, you might, but considering the difference in
price, I'd stick with the more readily available PC800 RIMMS.

Tim -

Thanks for the response and I'm in agreement.

I do wonder if anyone ever attempted to flash an 8200 with an 8250 BIOS
version, though.

The speed difference would - as you pointed out - likely not be perceptible
outside of benchmarking. Of course, the people who were screaming for BIOS
support didn't want to talk about that at the time. heh.

Thanks again.

Stew

It's not great, but it would be clearly visible on a benchmark (probably
not actually noticeable, however). The memory subsystem would be
significantly faster, but that is only one component of system speed.
It's importance varies depending on how and how much the software being
run accesses memory.

What about flashing an 8200 (known to have an 850e chipset) with an 8250
bios?

I honestly don't remember if anybody tried that back when the 8250 came out.

Some body would have to have a 8200 with the 850E chipset, some PC1066
RIMMS's and a willingness to take a gamble.

I have the first two, but not the last two. My 8200 has been running just
fine for the last 5 years. 'If it works, don't mess with it' I was taught.
