Can RAM run at different speed than FSB?

[Guest]

I have a question, but first my system specs.

MSI K7 Master (ms-6341) (bios ver 1.1)
Athlon 1333mhz
256MB Micron PC2100 RAM
GeForce3 (MSI)

It is set to stock - 133mhz, 10X mult.

Since flashing BIOS and running VIA 4-in-1, AMD AGP, Detonator 12.60 and DX8.1 I am now able to get through 3DMark2001 at 1333mhz, but I still get a RARE lockup. There is a utility that comes with the motherboard called FuzzyLogic. It showed the following:


Processor=1333
Bus=133
AGP=66.5
PCI=33
CoreVoltage=1.8
VIO=2.63
Memory=100

Is there any concievable way that the memory can be running at a different speed than the FSB? It is Micron PC2100 RAM 256MB, and it is supposed to be rated at 266mhz. Any ideas?

I'm not too firmiliar with the motherboard, or bios, but I'm guessing there should be a setting in there somewhere which allows you to switch the memory from 100 to 133, giving you the effective double pumped 266 MHz. It is as such on my ASUS board. I can switch the memory bus between 100 and 133. At both speeds, it will also increase with the increase of the FSB.

I'm entirely not sure about this one, but it also could be a jumper on the mobo itself. Never hurts to check

As with any potential motherboard problems, you should first fire off an e-mail to the motherboard maker... they will probably know more than we do.

While it is possible for there to be asynchronus clock speeds between the FSB and the SDRAM, the memory still should be at 133. I would check your bios settings. If that doesn't work, take the numbers off the chip and go to Micron/crucial's website to make sure they sold you 2100 DDR and not 1600 DDR

HCLK+33, HCLK-33, SPD. These are usually the options you might find in your BIOS as far as FSB speed...Sounds like you're Got HCLK-33 (Host Clock minus 33, so that would be the 133FSB - 33 = the 100FSB that you're showing)

The Master BIOS has a bunch of settings for Memory timings as well that I'm unfamiliar with though.

Hope that helps a little.
