What speed is my Memory REALLY running at??

Friends this has nothing to do with which os, to my understanding, but I posted this on lesser forums and stumped everyone. I predict that will not happen on this forum!

In theory my 'project' notebook, having i945GM chipset, is supposed to run the memory bus at either/or 266MHz or 333MHz. I have the two slots populated with matched 1GB 667MHz ddr.
When I pull up SIW to check, it says "DRAM Frequency 266.0"
It shows the modules themselves as "667 MHz"

So I go run MEMTEST 4.0, and it shows:

RAM Speed = 221MHz [DDR445]
FSB 133Mhz
CAS 4-4-4-12

no errors....

Can someone tell me what's going on here?
the Cpq BIOS/Setup is typically barren... no options to speak of, nothing at all about the various clockings...

It seems your memory speed is running at 266mhz each channel. Dual channel = 532 Mhz. Current timing 4-4-4-12-16 and if you have memory setting in bios you could change it to 5-5-5-15-20 and it will run @ 333Mhz each channel.

It seems you forgot the screenshot of slot #2 @spd tab.

makes sense
attached

is there another way to get there? the bios is threadbare, so to speak.
I think there are other cpq models with same basic platform... c500? other c300? guess I better search around and see if anyone figured it out.
i really hate having a capability that is being defeated by sloppy implementation...took me a week to find answers to getting real SATA mode enabled...no thx to hp/cpq

I guess your mainboard auto configure the ram to run at 266Mhz.
Try this Tweakers.fr (you may want to read the discussions about the software there).

I never use the software myself so be careful.

tweaker isnt compatible with my cpu/chipset. their other one, memset, should work but doesn't because it can't alter the first timing setting: all the others it can.

its odd to me that the chipset gets reported differently by the different snoopers... I get: i940, i943, i945... i guess they are all minor steppings of the same? anyway when I get time I'll try to find out if a diff c'set driver could allow the memset to deliver the goods.

Here are the basic specs of the notebook: Product Specificatons Compaq Presario C306US Notebook PC - HP Customer Care (United States - English)

As you can see, the processor runs at 1.73 GHz, and this is equivalent to an FSB of 133 MHz with a 13x multiplier or 266 MHz with a multiplier of 6.5x. Looking at the images you posted, I see the following:

Views: 541
Size:  14.7 KB

So it would appear that your FSB is 133 MHz with a multiplier of 13x, yielding a processor speed of 1.73 GHz. The processor power saving, if enabled, is achieved by automatically changing the multiplier dependant on system load.

To confirm this, can you show what you see on the CPU tab of CPU-Z ?
