Specs:

Intel e4300 /w Asus P5B-E
Antec P160 /w 2 120mm fans (running 100%)
2x1gb A-Data PC6400
Geforce 6200LE
Tuniq Tower 120 (fan running 100%)
Antec SmartPower 2.0 500w

Oc'ing results so far:

1. My system goes to 9x345 /w 1.45v in bios (actual 1.39-1.4 according to speedfan?) before it doesn't post anymore. It will boot into Windows, but Orthos fails after a couple of minutes.

2. I lowered it to 9x334 /w 1.45v and Orthos fails at around the hour and half mark.

3. With my voltage at 1.45, my core1 and core2 temperatures at load do not exceed 54C in speedfan. Intel TAT is about 72-75.

Potential flaws I have identified:

1. I need to raise my northbridge and fsb voltage. Right now I have them set at stock. Although some people say that this is only neccessary with Conroes (e6300/e6400, etc.) as they have lower multipler and thus require higher fsb for overclocking.

2. I have hit the FSB wall some e4300 owners are experiencing. Perhaps I should do the BSEL1 mod?

3. The power supply sucks. However this is just my test bench so the power requirements are light. I can't imagine the Geforce 6200LE, 1 SATA HD and 2 120mm fans stressing my PSU too much.

Questions:

1. I have seen someone recommending that you keep all your voltages, including CPU at auto. That way the motherboard will increase it as necessary without the user constantly testing it. How true is this, especially in the context of overclocking?

I know it's a long post, but I want be as clear and detailed as possible. Any help would be appreciated. Thanks!

1.45 i think thats still a lil bit 2 much, do 1.375 and have ur memories run 1:1 with ur fsb, so ur memories should run @ 667, and have em at 1.8v or 1.9 if they r cheap ram have em at 2.1, se eif it boots and if it works, disable all the cpu cfg's and see wats up. the temps on tat r the most trustable 72-75 seems a lil 2 high :X

Sweet JESUS you're using a lot of Vcore to get to 3GHz!! I get similar temps in TAT, but at 1.45V I can hit 3.2GHz; I can run 3.0 at 1.3375V.

I run everything on my board at STOCK/lowest voltages (not AUTO! the lowest voltages!) except Vcore and Vdimm and it is stable at up to 363 FSB (tested, limit not known). I don't think you need to bump voltages for 333FSB operation...

IMHO, if you need >1.45V to hit 3GHz, you have a 'dud' E4300.

What are you running your memory at? I don't think you need more NB voltage at only 345 FSB. Power supply is a good match for your setup also, plenty of overhead.

Have you tried a big FSB jump? Something around 360 or 365? Leave the CPU voltage where it is and try that, sometimes there is a "dead spot" in the FSB increments. Happened on my old ABIT NI8 SLI, would post at 195 x 20 on my D805, but not even post at 196-210 and perfectly stable at 220 x 20.
