Problem with OC on E4300 or...

[twjr]

I have recently set up a system as follows and decided to do some overclocking.

Cpu: E4300 (Revision L2, Stepping 2)
Mobo: P35 DS3C
Ram: Super Talent DDR800 4-4-3-8
Cpu Cooler: Ultra120 eXtreme

I figure they are all the components that will be involved in the OC.

Currently I have my cpu Oced to 333*9 @ 1.425v. The max temps I have ever seen while stress testing with Orthos are 50-51C so temps aren't a problem (though my two cores often have a difference in temperatures, sometimes up to 7 degrees). At this OC I am totally stable. My ram shouldn't be a problem as can be oced to DDR100 @ 2.2v with stock timings while stable. The mobo has +.1v on both the northbridge and fsb. So I try to push further and what do you know I hit a wall. I've tried 340 at 1.45v with no luck. Will boot but not POST.

So my question comes is there something else I should try or have I just got a bad chip?

Will boot but not POST? Post is that 1 beep you here when it has been succesfull, it's the very first thing your PC does. So I guess it doesn't even POST, because booting comes after Posting.

You could also have hit a FSB wall btw, and just to be sure, put your ram at 4/4/4/12 2t to take it out of the equation, then tighten the timings back later on when you can post and are stable at higher clocks. You might have somewhat of a bad CPU too though. 3ghz ain't bad, but with that ram and that cooler I guess you set out for a fairly high overclock. I don't know much about the NB/SB voltages btw, the intel rigs I oc-ed were all moderate OC's at stock voltages.

Sorry got mixed around there it POST's but doesn't boot.

I have had the ram both in and out of the equation and it makes no difference.

I'm not entirely dissapointed with the OC but yeah I had hoped of more. I really think I just lucked out with my CPU. I had thought of pin modding it but I'm not entirely sure where to start with that.

Dude, try 345, 350 or even 360-370fsb, maybe it's a fsb wall and it won't post there, but will post/boot at higher fsb numbers.

Could try adding some more juice to the NB/SB too, if you feel comfortable doing so.

Use 1:1 memory divider with 2.0Vdimm and 5-5-5-15-2T timing. Raise Vcore to 1.46.

I have to say I had the same experience with you on my E2160 which is same batch of Allendales as E4300. I got to only 2.9 with 1.325v and probably won't do much more unless it's 1.45v+ which is too high for me. I think the new batch of Allendales is problematic in OCing. Intel has probably but some corners somewhere, the newer c2d chips are just soso.

What happens if you try 8x400? or 8x402.

3 ghz is better than I got my 4300. They are a POS OC'er IMO.

How high can you go without raising the voltage? I'm stuck at 2.9 Ghz, becuase I didn't want to raise my voltage past 1.4V.

I don't think you got a bad chip - I'd say you have at least an average (if not slightly better than average) E4300. The E4XXX series are just not great overclockers. They are best paired with cheap components, since the quality of the rest of the components usually won't make much difference in the overclock. As an example, my E4400 will hit 2.8 Ghz easily cheap on a $25 refurbed ASRock motherboard and old DDR 400 memory and stock fan. when I upgraded to a better motherboard, faster RAM, and huge cooler, I gained a whopping 100 Mhz...

Sorry to bring back an old topic (though 3-4 days isn't that old) just have been without the internet for a few days.

I've tried the chip with higher fsb and lower multi and it will POST but not boot or bluescreen on starting windows.

Haven't really tested how far it goes on stock voltage but I was running it for a while at 266 on 1.25v stable.

Will have to try running it with the 1:1 memory divider when I get back from holiday in a week.

I guess there is always Penryn in several months that may be a more rewarding overclock.
