Current system:

AMD Athlon 64 3500+ Winchester (socket 939)
Asus A8N-SLi Deluxe
2x Corsair 1GB DDR XMS3200XL Pro TwinX (2x512MB) - 2Gb Ram in total in dual channel mode
ATI Radeon X850 XT PE
Enermax Noisetaker 600W PSU
Thermalright XP-120 CPU Cooler with Arctic Silver 5
Audigy 2 ZS

Ok, so I have a few questions for you guys & gals now, after reading some of the various posts.

Current BIOS Version - Phoenix-Award BIOS v 1016

Current BIOS Setup:

CPU Configuration Section:
DRAM Config
Max Memclock - 400Mhz
1T/2T Memory Timing - Auto
CAS#Latency - 2.0
RAS# to CAS# delay - 2
Min RAS# active time - 5
Row Precharge Time - 2

Hyper Transport Frequency - Auto
AMD K8 Cool & Quiet Control - Disabled

Jumperfree Configuration Section:
Overclock Profile - Manual
Overclock Options - Disable
N.O.S. Option - Disable
CPU Frequency - 200Mhz
PCI Experss Clock - Auto
DDR Voltage - Auto
CPU Multiplier - 11
CPU Voltage - Auto

Having looked at the various options, my limiting factors to my OC'ing ability appear to be as follows:
DDR Voltage - Only goes up to 3.00v
CPU Voltage - Only goes up to 1.650v

My questions now are as follows:

1. What should I set the 'Max Memclock' to as it currently 400Mhz?
2. Should I stick the DDR Voltage up to 3.00v & the CPU Voltage up to 1.650v to help stablize the system during OC'ing?
3. What suggestions do you have for OC'ing this setup?
4. Theres an option in the BIOS, cant exactly remember what its called, but has the options Auto, Set to CPU or 33.3Mhz. What should I set this to?

I did play around last night and managed to get it running as a 3800+, but had to reduce the 'Max Memclock' down to 200Mhz.

What is classed as a 'Ok', 'Good' & 'Very Good' OC for a 3500+ air cooled?

Cheers in advance :)
 
Cheers for the advice guy

1. Ill set the 1T/2T Memory Timing to 1T, will this help stabilze the memory when OC'ing?
2. Ill set the PCI-E Bus to 101Mhz
3. Ill set the other setting to 33.3Mhz
4. Shall i leave the memory divider to 400Mhz? It seems i have to reduce this slightly when OC'ing though, does that sound right cause I know if I reduce it it reduces the memory performance. Will this effect overal performance?
 
So far I think I know that I have to do the following:

1. Set the 1T/2T Memory Timing to 1T
2. Set the Hyper Transport Frequency to 4
3. Set the PCI Express Clock to 101Mhz
3. Set the PCI Lock to 33.3Mhz

Also I think i will need to then change the following:

1. Set the DDR Voltage to 2.9v
2. Set the CPU Voltage to 1.55v
3. Reduce the Max Memclock down to increase stability (will try 333 and 200).

I should then be able to increase the CPU Frequency gradually until I start getting problems, and then back it back down until it becomes stable again.

Dont know if these are any good OC'ing wise, but it seems stable and was running stress test without errors. Max temp under stress hit around 48.
