Asus P4P800, checking DDR ram speed with XP?

Hello,

Is there a simple utility that displays DDR-ram speed, with Win-XP.

I just bought some DDR-433 PC3500 ram, and want to make sure it's
running at 400Mhz (not 266, etc.).

Thanks.

p.s. Tried a small util called CPU-Z, but it doesn't seem to display
true DDR-ram speed.

Go there, its a utility that allows you to change FSB/mem etc while running
windows, it should report
the true speed, and even allow you to tweak it a bit.

The one for your Board is at:

The utility is Motherboard dependant, so you can only use that 2nd link for
P4P800 / P4P800-VM / P4C800 / P4C800-E
for other makes, people have to go to the first link and check to see if
their MB is supported.

Sorry, side note its for adjusting your FSB and AGP speeds, not memory, but
it will show you true values for RAM.
 
You can also use Sisoft Sandra -- which gives you tons of information about
your system. Here is a link to it:

Here is what it says about my RAM speed: note that it says "400 mhz data
rate" next to speed under the memory bank portion (note that it also shows
that I have PAT and hyperthreading enabled):

Thanks for the help, I'll try both programs.

Also DL'ing Sandra-2004. I just switched from W98 to XP, some of my
software programs are so old(!).


Might as well ask about this too:

In P4P800 BIOS, Advanced/Jumperfree Config/Performance, there are 3
settings:

Auto
Standard
Turbo

Sounds like 'Turbo' mode would be preferred setting. The manual does
mention turbo-mode but nothing else. What does this setting actually
change or do?

(...watching the other/new topic about PAT setting)
 
No. SATA has nothing to do with PAT -- I don't even have a SATA board.

PAT is enabled in the P4P800 by setting Memory Acceleration in the bios to
"enabled". I don't know if your board has a similar setting in the bios.
PAT can also be enabled in the P4P800 by setting "performance mode" in the
bios to either the "standard" or the "turbo" settings. Again, I don't know
your board's bios.

Also, no matter what, PAT generally becomes disabled (at least partially)
when you overclock.
 
From experimentation, it appears that the peformance mode when set to either
"standard" or "turbo" does two things:

1. it enables PAT (assuming you are not overclocking) -- Performance
Acceleration Technology

http://www.xbitlabs.com/news/mainboards/display/20030528093951.html

2. it changes the memory timings to what may be more efficient timings,
assuming your memory can handle it.

For instance, in "auto" under the "performance mode", with the "serial
presence detect" elsewhere in the bios set to enabled (so your memory timing
is auto detected), my memory timings show up as 2.5 3 3 8.

When I enable either "standard" or "turbo", the timings show up as 2.5 3 3
6. Under a previous bios version, "turbo" tried to change memory to 2 2 2
5. My memory couldn't handle that, and I couldn't boot in "turbo".

Ok... was confusing it with the Intel Application Accelerator (or whatever
it's called).

Definately overclocked here, sot PAT stays off!

This info is very helpful!

Since updating the P4P800 865 chipset from Intel's website (v5.0.2 I
think), things 'seem' to have not been as stable. Your post basically
explains why (overclocking the CPU, and 'turbo' combination probably).

Thanks.
