e6300 or 6400?

Getting stuff for my next build. Should I just go with an E6300, or the E6400? There's a $40 price difference @ newegg right now ($180 vs $220). I could probably use that $40 to get myself a nice heatsink to go along with the E6300. Either way, I plan on overclocking the crap out of whatever I decide on. So what does everyone think, E6300+heatsink, or E6400? Are there even any advantages to the 6400 over the 6300? :confused:
 
The E6400 has the higher multiplier which means you won't hit the motherboard's fsb wall or the ram's max as fast, usually giving higher OCs. It's also speed binned so the core itself should be better than an E6300.

You can't overclock much without a good cooler anyway, so you better buy at least an AC Freezer Pro ($30) with either CPU. Depending on how long you want to keep the processor, the difference between 2.8-3.2 (E6300) and 3.2-3.4 (E6400) can be worth $40.
 
The multiplier is the biggie.

The extra $40 is worth it, as you won't have to force yourself to buy expensive RAM in order to hit the same overclock.

The E6400:
400MHz FSB x 8 Multiplier = 3.2 GHZ
Your RAM will be doing 800MHz, so buy any PC6400 RAM

The E6300:
400MHz FSB x 7 Multiplier = 2.8 GHZ
To hit the same 3.2GHz overclock, you will need faster memory.
 
You don't always have to buy faster memory for the e6300... You can run your ram asynchronously although it's better to run synchronously... You lose like 2-5%...

Ya... me coming from AMD and over to Intel, I understand it's not as big of a performance loss to run asynchronously, but it just seems freaky and I don't trust it :p But ya, it's an option, but hey, for $40 you can save on the Memory, go with the faster CPU.

P965 does not do that.
 
8x450 would sound nice :cool: Three from five 6400s that I've tested did that completely stable @ around 1.45V :D

If you had 6300 you would need at least 500fsb capable board and no board will do 500+ without raising NB voltage
 
I say go with the E6400. It's worth the extra 40 dollars. My buddie is selling a E6400 for about 160 or more, if you want it PM me. (Please excuse me for discussing this in the wrong place mods. and users.)

Actually, that is false. The 965P-DS3 offers RAM:CPU ratios. Whether they work or not, I havn't tested to be sure, though I doubt that Gigabyte would offer the option if it didn't work.

There is nothing lower than 1:1, which is what he was saying.

Also, you don't really have to spend that much more on RAM for an E6300.

If you want an Orthos stable system with air cooling, you will rarely get over 3.5 GHz with an E6400/6300.

Generally 3.4 GHz range is normal, which means all you need is a semi decent mobo like the P5B-E, some good D9 RAM like the Buffalo Firestix for $241 on newegg, & an E6300.

Saves money over the E6400 for the same results.
 
Well, I got 3.4 out of my DS3 (a cheaper board) in combination with some generic D9GKX. You don't have to buy brand-name memory to get the performance.

I have a DS3.

Where'd you get generic D9GKX? :eek:

where the FSB on the conroe is 1066, and DDR2 would be at 800, won't he need to set the ram divider to 4:3 in the bios? the E6400 is 266x2x4 which = ~2.128Ghz. (266 not 400.)

I fail to see a P965 chipset in this article :confused:

Also I should have said in my original post that it does not do under 1:1. You can, however, run the memory faster than the bus speed.

I finally tried a Core 2 Duo on my P5B... Yup it can't do it... Hmmm... I guess I'll have to look for E6400 or 6600...

conroe 1066 you gotta remember is QUAD PUMPED not dual like ddr. so 1066 really has 266fsb. where 800ddr2 would be 400. so it's actually 266:400 so it's actually 2:3.
I'm running 266fsb and 333 ram so that's actually 4:5

:)

how can i confirm the mobo i want will allow me to tweak the ratios in the bios? I'm looking at the intel G965Express mATX board. the newegg reviews/stats don't clarify.
 
6400 FTW

6300 you'll likely be limited by your motherboard or ram for the max overclock.

With the 6400, you'll minimize that risk.

wouldn't it be 4:3 because 1066/4 = 266 and 800/3 = 266?

i'm spinning!
 
Just got it in the mail. Week 31, and A567 "code". Anyone have any information about it? I don't see any other A567's in the overclocking database. :confused:
