E8400 or not??

I currently have as in my specs. But i have been considering getting an E8400 when i get my TRUE and i was not sure if it was worth it. I would be aiming for a rather high overclock, 4.2 or higher hopefully. I would have thought that the extra speed would be more worth it over the extra cores when gaming and doing day to day things but was not sure, any input would be appreciated,

Thanks in Advance

Shoot for e8500 or e8600. If you go 8400 it HAS TO BE an E0 stepping, otherwise 4+ is just a decent voltage pipedream.

EDIT: With the new cooler, how high can you get your existing Q6600??

i would stick with the q6600. almost equal in performance and you won't see much of a speed boost past 3.6ghz anyway. plus i guarantee you that you will miss the 2 extra cores in terms of functionality.

Unless you are encoding or something along those lines you'll notice the E8400 to be a bit snappier when surfing/gaming as long as you get an E0 and it's a good overclocker.

Havent got the new cooler yet unfortunately. Hopefully won't be too long, my Q6600 can pull off 3.6Ghz @1.425v Stable but with this cooler (POS) wouldnt run it 24/7. I'm guessing that with a TRUE i could probably pull it off with lower volts and maybe get 3.8 if im lucky, so if i cant get much more than 4 with an e8400 it may not be worth it if i can almost get my q6600 there, have i got my thinking right??
Also, on a related note, would a Scythe S-flex 1600rpm be a good option for the fan to attatch to my TRUE when i get it?

Avoid the E8400. I only say this because I got a C0 and it sucks rather hard. I bought from newegg some 2 weeks ago and I've tried to OC this thing and its pretty crappy.

I can't get 3.6Ghz at 1.36 vcore / 1.4 NB voltage / 1.35 CPU VTT / 2.125 VDimm (rated at 2.1v)

EDIT: And that's on my DFI board too >_<

Dude that's why you order from Tank Guys to get the guaranteed E0 or buy from an individual seller so you know what the stepping is. Some people get lucky with the C0's most don't

To the OP:
In my opinion I would just keep the Q6600 we are splitting hairs here especially since you have a decent overclocking Q6600 on yours hands.

I have C0 stepping and mine is 4.2ghz stable, and easily boots windows at 4.5ghz, just need to fine tune for 4.5 I think. E8400 was a very good purchase in my opinion, and usually a great overclocker.

C0 revision* lol i dont know why i said stepping

I do encode occasionally but i have not got any good multi-core encoders so i am not using all 4 cores anyway. But lets say i could get my q6600 to 4ghz (crosses fingers) how close would that take it to an e8400 at 4ghz+? any people with experience with this kind of change i would appreciate the input.

Think about this
4 cores at 4ghz vs. 2 cores at 4ghz (highly unlikely with the Q6600). The Q6600 would own simply because it has more cache and cores.

So its more of a mixed bag for e8400 overclocking than it is for some of the other Core 2 Cpus?

I've been able to boot at 3.85Ghz, although it gets to hot for my liking, it will actually run Prime95, do you think that with a TRUE it could reach this speed or above at acceptable temps?

Someone was just having a hard time overclocking in general


lol but seriously, C0 stepping is not bad, 4.2ghz stable is a pretty good OC, I have it and I know it easily boots windows at 4.5ghz too, so nothings impossible.

I did, but in things other htan benching, i love my multitasking, but in single threaded apps would it really be faster on a quaddie considering that the 45nm chips can execute more instructions per clock? i havent seen any direct comparisons, hence why i ask.

EDIT: If i were to stick with the quad and go for 4Ghz what would be a safe voltage, i can get to about 3.8Ghz stable with 1.55v, i know its a bit high, but i'm assuming that with a better cooler the voltage required would probably drop, maybe enough to safely reach 3.9 - 4 if im lucky

In single threaded apps (mostly everything) the Core 2 duo at the higher clock speed will be faster, specially since you can get the E8400 up and above 4ghz, its a pretty good performer, and I do multitasking and never really notice any slowdown with quite a few apps running.

Hm... looks like i have some decision making to do here. Maybe it would be better to just get a TRUE for now and stick with my Q6600 until the Nehalems come out.

EDIT: But i still have the question of the max safe voltage for a q6600 on a TRUE

I ran a q6600 at 3.6ghz and my current E8400 at 4.4 the E8400 is noticeably faster. You will not notice any real world performance difference due to th E8400 executing more instructions per clock. Goodluck in your journey to find somebody that has compared the two both at 4ghz.

Edit: I think you are already pushing it at 1.55v intel recommends you not go over 1.5. I've heard of people running higher voltage (around 1.6v) and not having a problem.

I think i may just stick with the Q6600 and see how far it will go, it will be approximately AU$300 cheaper lol. I seem to have gotten a pretty good Q6600 from the looks of it anyway it does have a VID of 1.3 but seems to do better than some with lower. But i think it's probably best to give it a go with a new cooler first and then decide later
