Anyone overclock a retail e4400 yet?

[LagunaX]

Got my 2gb supertalent ddr2 667 ram and a 1066fsb modded mobo - deciding between the e4300 ($115) and the e4400($140). 90% of the e4300's can hit 2.7ghz on stock volts/cooler. Anyone try an e4400 yet? I've googled a lot and there are no posts for retail e4400 overclocks either on stock or increased volts. I'll be ordering tomorrow! :cool:

Looking for the same info, though I'll wait a bit more, so here's a friendly bump :)
Me too, I've only seen a few E4400s, many were ES, but they seem to have the
same FSB walls, or OC limits (despite the higher multi).

I got mine on saturday. I bought it from ebuyer in the UK for £81, and paired it with a DFI Infinity 975X which I got on clearance for a good price and some VData ram. You can tell I wasn't really aiming for much! but I was upgrading from a P4 630 so I would have been happy with stock performance anyway even if it didn't overclock.

Paired with a Scythe Infinity and a Yate Loon 12cm fan I upped the fsb to 266Mhz. Booted no problem and was dual Prime stable. Vdroop on the motherboard is a shocker so I upped the vcore a little bit to 1.36v and went to 300Mhz. Again, no problem whatsoever. Under load the vcore drops to 1.328v, but under full load temps stabilise at 52°C so there should still be plenty more to come if the board is up to the task.

This was done in about 10 minutes, and since then I haven't played with it any more because it's rock steady and is more than enough for my needs. I'll have another crack at it tonight and report back with benchmark scores and week/batch numbers etc... (off the top of my head I think 1M SuperPi was ~21s, but I'd have to double check to be certain)

Couldn't resist and picked up an e4300 retail for $110 shipped off of ebay new. A couple of newer posts on the web suggest that they both hit around 3.2 ghz before they require a big increase in vcore so the $40 difference (price/tax/shipping) wasn't worth it to me. But will follow this thread just to see what "could have" been mine...

Well I couldn't get it above 3.25Ghz stable, and it needed 1.36v under load to run at that speed. Load temp was 55°C and SuperPi 1M completed in 19.917s.

Overall not too bad for air cooling, but given that it can do 3Ghz@1.31v I was a bit disappointed I couldn't get higher without upping the volts significantly. Even though the temps stayed low, I wasn't going to risk frying the chip within a week just to eke out another 500Mhz. Still a good chip for the money, but not significantly better than the E4300.

There are a few results here with the E4400s on a ASUS P5W64 WS Pro.

You may have to sign up to check it out though.

Long story short two E4400 from the same batch and pack date were tested and one did 3.45Ghz the other 3.65Ghz

That's using a very good FSB overclocking board though which leads me to believe that it's an FSB limitation rather than a CPU limitation holding back the E4400s.

nice. my E4400 hits 3.68 today with aircool on my P5WDH (Zalman 9700LED)

Nice. What vcore are you running for orthos stability? Did you do the 266 - 1066 fsb bsel mod?
