Is there a way to check what the speed of my RAM is running at??

OK, I'm running:

Asus A7N8X Deluxe
AMD Athlon XP 2600+ Thoroughbread-B
512 Dual Channel DDR400

Core Speed 2081 MHz
Multiplier x12.5
FSB 166 MHz
CPU Voltage 1.65

Thanks

If you set "Memory Frequency" to 100% in BIOS, ram will run at same
speed (in sync) as FSB setting.

If your RAM is set to SPD, probably 200MHz.

If your RAM speed is 100%, then 166MHz

If your RAM speed is set to x%, then it's x * 1.66MHz.

I would set the memory timings manually and set the speed to 100% of FSB.

Actually, I found it...It says:

Memory Module Properties
Module Name Kingmax MPXB62D-38KT3R-PEA
Serial Number None
Module Size 256 MB (1 rows, 4 banks)
Module Type Unbuffered
Memory Type DDR SDRAM
Memory Speed PC3200 (200 MHz)
Module Width 64 bit
Module Voltage SSTL 2.5
Error Detection Method None
Refresh Rate Reduced (7.8 us), Self-Refresh
Highest CAS Latency 2.5 (5.0 ns @ 200 MHz)
2nd Highest CAS Latency 2.0 (7.5 ns @ 133 MHz)

So I guess it's running at 200 MHz??

That look like it's SPD info... which is basically text stored in a chip,
and doesn't actually relate to the current settings. I could be wrong, I've
never used that program, just pointing out that it might not be what you
think it is.

where did you find that?

Looks like it.Shouldn't it be @ 133(266)?
 
PS
If your XP2600 is a 166/333 CPU then that RAM should be run at 166/166
with the FSB?
Click to expand...

No, it can run fine on 200MHz, DDR400. I'm unsure about it having any
advantage though. Might depend on rams latency and number & config of
ram sticks. Higher memorybus could reduce latency. My own experiments
hint's that DDR333 CL2 seem to be somewhat faster than DDR400 CL2.5
though. At least on 333FSB, two symmetrical DIMMs and dualchannel.

Well this is what I'm running now:

Core Speed: 2088 MHz
Multiplier: x10.0
FSB: 208.8 MHz
BUS Speed: 417.6 MHz
CPU Voltage: 1.696v

Memory running @ 100% of FSB, so RAM is running @ 208.8 MHz

CPU running at 41 Degrees Cel. Under normal usage/49 Degrees under heavy
load
MB running at 23 Degrees Cel. Under Normal usage/25 Degrees under heavy load

Is this ok??

I thought your RAM was capable of running at 166/333 speed?

Well, does the increased bandwidth affect your performance so much it
justifies so hard overclocking of the FSB? You are overclocking the
cpus FSB hard, but core, chipset and ram moderately.

I'm not an expert on overclocking, I avoid it myself. But if you're
looking for best performance, I doubt it should be so unbalanced?
But someone more experienced with OC should comment this.
Temps are ok.

Nominal for your system is: (on the off chance you're asking ;))
166 FSBclock, multiplier 11.5, 100%, DDR333 CASL 2 or 2.5 (there's a
good chance PC3200 CL2.5 will work fine with CL2 on DDR333).
That's how I would (meekly ;)) do it.

You can run the memorybus above 100% (and that was primarily what I
was thinking about) but I'm almost sure it's not a good idea with
dualchannel and reasonable DIMMs.

There's nothing that needs "balancing" when you overclock. You just take
everthing as fast as it will go :-)

The FSB is usually quite capable of 200MHz (the rest of the chip is often
capable of 10 times that, so why not?), often you can reduce the multiplier
and you're fine. Increased memeory bandwidth is beneficial in many
applications.

I use aida32 all the time to compare systems.

The thing to watch is the benchmark read and
write times. Check them before and after you
make your speed changes. The speed they are
running at isn't very telling. What is telling is the
time it takes to read and write to ram which you
can check with Aida32's benchmark routine.

It's under system, at the bottom of the right hand panal.
