|What cpu speed and model are you trying to use? |
What sizes of ram modules do you have installed?
What types of ram do you have installed? - PC1600 (200mhz), PC2100 (266mhz), PC2700 (333mz), or PC3200 (400mhz)?
Are the ram modules single sided (chips only on one side) or double sided (chips on both sides)?
Which of the three ram slots do you have which ram module installed in, slot one being the one closest to the center of the mboard?
I took a look at the Asus manual for your model.
In the bios Setup.....
CPU Speed - default is Manual?
"When the motherboard is set to JumperFree mode, this field allows you to select the internal frequency of the CPU."
In that manual I do not see any jumpers on the motherboard for enabling/disabling JumperFree mode.
Since Asus doesn't normally omit information about that, I assume there are no such jumpers on this mboard and you can select CPU speed - JumperFree mode instead of Manual.
If you select JumperFree mode and you STILL get messages you have the wrong settings for your CPU speed, the cpu is running overall slower than it was designed to - the only thing that can cause that is either
- all of the ram modules you have installed, or at least one of the ram modules you have installed, DO/DOES NOT support the fsb speed requirement of the cpu you are using. The max the bios automatically runs the ram at is at the SLOWEST specs of all the ram installed.
- you have some other setting(s) wrong in the bios Setup
The manual says something along the lines of if the multiplier is locked on the cpu itself, in this case to X13, you can't change that in the bios Setup, at least you can't and have it actually "stick" when you Save bios settings.
"My current setting is "manual"(internal) 26x (multiplier) and 100 for external freq."
You mat be able to select X26 in Manual mode, or other settingsthat are wrong, but the setting won't "stick" - be retained - when you Save bios settings if the cpu multiplier is locked on the cpu itself, and/or if settings aren't appropriate for the ram you have installed, and/or aren't appropriate because of other settings in the bios Setup.
"...100 for external freq "
The manual doesn't mention what your other choices are.
are they 133, 166, and 200mhz?
Bios Setup settings can be confusing.
e.g. PC1600 (200mhz) ram uses 100mhz externally but because it's DDR ram it's data rate is doubled and in effect the ram itself runs at 200mhz
The max fsb speed available to the cpu is double the DDR ram speed.
The multipler figure is usually what you multiply the external mhz the ram is actually running at (at least it is on my older Asus A7V600), or the lesser mhz the bios is set to otherwise that the installed ram supports, to arrive at the overall cpu speed.
E.g. on this mboard 13X 100 (1.3ghz overall), or 13X 133 (1.7ghz overall), or 13X 166 (2.1ghzoverall) , or 13X 200 (2.6ghz overall).
PC1600 ram or faster can be used with a cpu that requires a 400 mhz fsb speed, but PC1600 ram can't properly support a cpu that has a 533 mhz fsb requirement, the max fsb speed would be 400mhz, and the cpu would run slower than it was designed to run at - at 75% of it's speed.
On this mboard you can't use a cpu that has a 800mhz fsb requirement unless all the ram is PC3200 (400mhz) ram, and you can't use PC3200 (400mhz) ram, or at least you can't have it run at 400mhz, unless the cpu that has a 800mhz fsb requirement .
Apparently your mboard has 3 ram slots, each slot can support up to and inc. a 1gb module, BUT
- the total max amount that can be supported is 2gb
- you can only use PC3200 (400mhz) ram on this mboard if the cpu uses an 800mhz fsb speed (, or , at least, you can only have it run at 400mhz if a 800 mh fsb cpu is installed).
- the first slot can use either single or double sided modules, but the other 2 slots can only use a double sided module in slot 2, no ram in slot 3, or a single sided module in either of or both of slots 2 and 3
- ram modules with 16 bit chips are not supported by this mboard
