Nice work!
I think I have the same memory as you, so will have a go at slackening off the timings and see if I can hit 4Ghz.
What voltage are you entering in the bios to get that?

Topitoff, I see you have FS2004 on your PC, have you tried it out yet? Noticed any benefit?
With native 1333MHz FSB what does this mean for overclocking? I mean the multipliers are low so to get high overclocks the FSB will have to very high.
I mean I have an E4300, it runs at 9x200MHz = 1.8GHz. The 200MHz when quad pumped gives 800MHz. To overclock the 1.8GHz stock to 3.2GHz I just have to up the FSB from 200MHz to 356MHz (1422MHz when quad pumped). No problem at all and below the spec of 800MHz PC6400 RAM. A 78% overclock with no problems.
These chips though, based on 1333MHz (333MHz actual) need the FSB to be pushed to almost 600MHz to get a similar 78%. That’s not going to happen! Maybe around 450MHz is the highest we can reliably hope so only a 35% overclock.

Thanks, no you don't have the same RAM, replaced it with Ballistix PC8500 as anything over 470 FSB was "flakey". Now I can go for max. suicide run, I wanna try for <10s SuperPI 1M
Vcore is 1.52v

Ah I see! Apologies!!
This overclocking lark is mad, I said to myself I'd be happy with 3.6Ghz, but then thought 'no, if I got some faster RAM, I could hit 4Ghz+'...
Off to source some 8400 RAM now. Where will it end?!!

I’m pretty sure the die's are orientated the same way as the old C2D's, mobile duo's are the only exception.

great post, thanks
Finally got FSB of 500 - Now I'm not saying it's anything like stable! Will do SuperPI 4M
So close to breaking 10 secs

It should with a bios update.

Booted at 4Ghz, just confirming memory is stable first and for most. Managed to get into windows at 1.335v bios so things are looking promising.
I need 1.360 (cpuz) for my E8400 at 4GHz to be stable,btw tom can you check your gmail?
Fitted an E8400 into a Gigabyte GA P35 DS3P (4 x 1GB Crucial Ballistix PC25300) this afternoon, running it at 4.2GHz @ 1.375v at the moment, was able to get 4.4GHz @ 1.425v, however, would not boot at 4.5GHz didn't play around with setting in BIOS due to time availability. Must say am very pleased with it so far....
Soldato
is that confirmed stable jbloggs?
Have you ran prime yet?
