Help needed - AMD 3500+ , asus A8V

[Jawad]

I am overclocking from the Bios.

HT frequency
- 200mhz

Memory
- 5:3 DDR 333
- CAS Latency 3.0
- 2T command disabled

CPU
- FSB @ 250mhz
- Multiplier : 10.0
- Stock Voltage (1.5v)
- AGP/PCI Lock enabled
- DDR Voltage - AUTO
- V link stock 2.5v

Sandra 2004 says mem clock speed at 208mhz x 2 (416) or something along those lines.
I do get a warning at end of sandra stating :
- Memory bus speed exceeds memory rated speed, reduce memory bus speed
- Memory bus speed exceeds chipset rated speed, reduce FSB/memory multiplier

With these settings, through the whole 1hr 39min till Prime95 gave me an error, i was @50C max.
Was running the torture test in Prime (one that says max heat tested, some ram)
and got an error after 1.5+hours stating:

Fatal Error: Rounding was 0.5 , expected less than 0.4
Hardware Failure Detected

What settings should be tweaked?
I am a noob to overclocking, but i didn't just guess the bios settings. I did plenty of reading.
I did however make ram adjustments blindly.
Help me out.

somebody ?

Try bumping your DDR volts upto 2.7, maybe bump your CPU volts upto 1.55v. If that doesnt work, you may just have a CPU that cant do 2.5, i dont think your memory should hold you back, although its only rated at 200 and you are at 207.

hmm i raised the ddr volt to 2.7 and it got 1 error after 25minutes.
kept the cpu volt still stock...

what about my memory? its to CAS 3, but i made it that, from cas 2 i believe. is that what it should be at?
here is my ram : link to newegg specs

and what about this :

5:3 DDR 333

i changed it to that from 1:1 i believe. what should it be at?
what will make my error go away
