AMD K7 3000 400 MHz CPU (without the plus sign) and MSI K7N2 Delta Mobo - CPU Freq. Problem, not ma

I purchased a AMD Athlon XP 3000 CPU from New Egg for what I thought
was a great price at 267 dollars for the 2.1 Ghz version of this CPU.
I didn't notice that the CPU isn't the 3000+ but rather just 3000
without the plus sign. The fastest I can set this CPU to run is 1670
MHz instead of the 2100 MHz that it is advertised to run at. When I
try to set the mutliplier in the Microstar K7N2 Delta mobo to 13.0 it
defaults the CPU down to 670 something MHz! A whole GHz slower!

Anyone? When I go to the MSI web site it doesn't show this mobo
supporting the AMD 3000, only the 3000+ etc...!!! Maybe I
misunderstand, that they only left the plus sign off of the page at:

because I linked to this page:
http://www.newegg.com/app/manufacto...frcode=0&propertycode=&propertycodevalue=4159
where they show it as having the plus sign!

ANYONE have any suggestions for me??? I would like to have this baby

AXDA3000DKV4E breaks down
it is indeed a 3000+, the 200fsb version
if the fsb is 200 then that will put the multiplier at 11.5 then you should
be set to go..
not too sure where your getting 13 multiplier from?

 

It appears that I did get a AMD Athlon XP 3000+, just that they left
the plus sighn off of that one web page. Still, I can't seem to figure
out how to set the BIOS to get it to run beyond 1670 Mhz, why the
multiplier of 13X only gets it to 600 some MHz is a mystery to me.

 

On my KT4 board if I go above 12.5/13 multiplier to 14 or 15 times, the CPU
also runs at about 500. Go figure!!
If you find a solution , please let me know : )
Maybe the actual setting is 4 X and 5 X but the bios shows it wrong ?

 

AXDA3000DKV4E breaks down

If I set the multiplier to 11.5 then the CPU clocks at 1537 Mhz. I'm
really dumb founded on this problem. I set the FSB to 200!

 

The mobo will allow a multiplier of up to 13.0 but that makes it drop
back to 667 Mhz, or somewhere in the 600's.

 

FSB doesn't seem to be correct. 10.5x200 should give you the 2100mhz. Check
FSB again, set multiplier to auto.

That sounds really weird..
Maybee the 5th bit is missing so it turns it all the way down instead of all
the way up? ..
I don thave the tables showing the sequences for the multiplier but you
could see what hte last 4 bits are for a 13 multiplier and then look to see
what those four bits are on their own..

I would stick with the stock multiplier and try a lower fsb, maybee 166 and
just "See" if that makes a difference

 

Thanks for your help brothers, but I have it working now. Apparently I
had some things set up wrong in the BIOS. I kept at it until I found
settings that would work, I don't remember where I went wrong before
or which ones caused the problem, however, here are the current
settings that work:

(Under the advanced settings)

Current CPU Clock 2100 MHz
System Performance: Manual
CPU FSB Clock [200 MHz]
CPU Interface [High Performance]
FSB/DRAM Ratio [BY SPD]
Current DRAM Clock 200 MHz
Memory Timings [High Performance]
X-T-(RAS) 8
X-T(RCD) 3
X-T (RP) 3
X CAS Latency 3.0
X FSB Spread Spectrum DISABLED
X AGP Spread Spectrum DISABLED

(Under Frequency/Voltage Control)

AGP Clock Control [DEFAULT]
X AGP Clock Value 66
AGP Voltage Adjust [1.5V]
DRAM VOltage Adjust [2.7v]
CPU Ratio [BY H/W]
CPU Vcore Select [BY H/W]

I'm letting the BIOS select the multiplier by hardware. Works great
now and gives a good 3DMark2001 overall score of 16767 using the ATI
9800 PRO GPU.

 

I had to re-do the BIOS today do to OC the FSB too much, when back to
default. I found that the only way to get the MSI K7N2 Delta mobo to
recognise the AMD 2100 MHz Athlon 3000+ to boot to the 2100 MHz freq.
is NOT TO TOUCH ANY OTHER SETTING in the BIOS, just change the FSB
from 100 to 200 and then reboot! Once you do this once it ought to
boot at the proper CPU frequency and then you can change other
settings. If you change anything else first, your screwed and will be
stuck far below the proper CPU frequency. I had to pull the BIOS
battery to get the BIOS back to the factory default.
