Athlon 2500+ A7N8X-E DLX bios settings

Hello!I'm new in forums and need some help.
My system: Athlon 2500XP+ ASUS A7N8X-E DLX KINGSTON 3200 256x2 120Gb Seagate MSI 5200FX 128T
I want to overclock my cpu.But the best i can do is 1980Mhz.
My bios settings are:

CPU EXTERNAL FREQUENCY :180
CPU FREQ MULTIPLE SETTINGS :AUTO
CPU FREQ MULTIPLIER :11.0X
SYSTEM PERFORMANCE :USER DEFINED
CPU INTERFERENCE PTIMAL
MEMORY FREQUENCY :AUTO
RESULTING FREQUENCY :AUTO

xSDRAM ACTIVE PRECHARGE DELAY :6
xSDRAM RAS TO CAS DELAY :2
xSDREAM RAS PRECHARGE DELAY :2
xSDRAM CAS LATENCY :2T

FSB SPREAD SPECTRUM ISABLE
AGP SPREAD SPECTRUM ISABLE

CPU VCORE SETTINGS :AUTO
xCPU VCORE :1.65V
GRAPHICS APERTURE SIZE :64MB
AGP FREQUENCY :AUTO
SYSTEM BUS CACHEABLE DISABLE
VIDEO RAM CACHEABLE DISABLE
DDR REFERANCE VOLTAGE :2.6V
AGP VDDQ VOLTAGE :1.5V
AGP 8X SUPPORT :ENABLE
AGP WRITE FAST CAPABILITY :ENABLE

CPU is locked.When i change multiplier it doesn't effects current speed.
When i increase cpu external freq to 191 bios doesn't boot when i diseable the halt on option windows doesn't start and a message appears
"file missing" <windows root>\system32\ntoskrnl.exe"
The temperatur observed in asus probe is 44-45 (i dont know if it is normal).What is the limit temeperature that cpu can work safe?
I dont have any information about ram timings.How must i change them?

What means MEMORY FREQUENCY :AUTO? What is the difference between MEMORY FREQUENCY :BYSPD

I'dont have any information about voltage? How must i change voltages and some other values when i increase external clock frequency?
I'm new in this overclocking world and need some help.
Thanks!

Why disable AGP Fast Write?

AMD XP-M 2600+ @ 2.6Ghz (12x216Mhz)
Gigabyte GA-7N400 Pro2
Geil 2x256MB PC3200 DDR (2-3-3-11)
Gigabyte Radeon 9200 128MB VIVO
WD 36GB 10,000RPM 8MB SATA
Maxtor 40GB 7,200RPM 8MB ATA133

Notice you have the mobile chip in your rig. Wat voltage are you using at your current setting?

Barton 2500+ @ 2200mhz (10x220 vcore @ 1.8)
Asus A7N8X Dlx 440 FSB
1gb Geil GD pc3500 Dual Channel (2-3-3-6)
Segata 80gb SATA 8.5ms seek
ATI Radeon 9800 Pro(420/720)

hmmm...i think i'll go home tonight and see if turning of the AGP fast write gives me any more OC...i still want to try to get it up to 2.7Ghz, that was my goal when i got the chip (hopefully at 12.5x216). i think i can once everything gets settled, and i do some more tinkering.

Gigabyte Radeon 9200 128MB VIVO
WD 36GB 10,000RPM 8MB SATA
Maxtor 40GB 7,200RPM 8MB ATA133

hehehe...thinking of getting one too? umm...i'm a rookie on this board, so i don't know how to post a link, but, heres the url:

http://www.ocinside.de/go_e.html?/ [...] inmod.html

change the first drop down box from "cpu view" to "socket view", and the last box from "FSB selection" to "200MHZ FSB". it should show 2 lines on the diagram. what i used to connect the soceket holes was 2 sinlge strands of wire from a standard wire, each cut about 1 cm long. just bend it in a "U" and drop it in the socket holes. then put the CPU in and lock it down. when i booted up my computer, it automatically booted at 200 FSB...i had the multiplier set to 11 already from my old locked barton 2500+, so, first time i booted with the mobile chip it booted right to 2.2Ghz, no problem, stock voltage, the system totally thought it was an XP 3200+.

heres a link to another thread that talks about this if my description isn't enough for you...

why anyone would ever buy a locked 3200+ for $200 more than an unlocked XP-M 2500+ i'll never know...
