Basically asking if there are any models I should stay away from.
Trying to decide which one to get and I have a budget of no more $190.
Thinking about the E6320 with a DS3.
Also can the 1.8mhz chips oc to the same place the 2.4 and higher chips can?

C2D's are all great overclockers on decent mobos. The 1.8ghz chips won't OC so high but you save a lot of money by buying something like an e4400 and getting it to 3.0ghz rather then buying and e6700 at stock.
By a decent mobo I mean one that doesn't limit your FSB as some have been found to do.
Iv heard that the 4300s OC like hell...but i dont think there are any that dont OC very well.

The mobo I was thinking about getting is a DS3 1.3rev.

Is the E6420 the best choice for my $190?

now it is.
wait for the price drop pick up a quad core for 266 and laugh at the rest of us.
or i think the e6600 will be in your range at that time

wow thats news to me :rolleyes:
The E4300 is a PROVEN overclocker, I haven't heard anything anywhere that has shown the 4400 to be any better. They are both the same core and in the end it is a matter of luck of the draw. The difference between a 9 and 10 multiplier is nill unless you have a $30 motherboard.

If they all oc to about the same level , why not just buy the cheapest one? Like the E4300. Any difference between it and the E6320?

Which is the cheapest chip with the same l2 cache as the e6420?
Simply stated what does L2 cache do?

This has been said so much it's a cliche, but:
Nothing is certain in the overclocking world. Overclocking capability is also relative to the level of stability you demand. Some people boast 3.6 "prime stable" overclocks on air that BSOD every thirty minutes due to "driver issues." I've known others who RMA their processors until they get a good overclocker. Dishonest but that's what a lot do.
Processors, even with the same stepping, will have outliers. I've seen 10% variance of the overclocking between processor of the same week and stepping on the same equipment. Some will overclock better than others. Unless you're lucky or connected enough to get cherry picked parts, you're at the mercy of the dice.
Taken as a whole, the C2D is the best overclocking option available, any C2D. How much depends on the quality of your supporting equipment, your knowledge, cooling, and the overall room enviroment.
Just don't get your hopes too high. If you do, you're more liable to get dangerous with your voltages to meet expectations and fry equipment.

The e6320 is the cheapest with 4 MB L2 cache.
L2 is simply fast on-chip memory that the processor can use instead of slower main memory. Here (http://www.xbitlabs.com/articles/cpu/display/pentium-e2160_4.html#sect0) is a review of the new Pentium E chips with 1 MB L2 compared to the 2 MB and 4 MB varieties. 2 MB of cache instead of 4 MB doesn't impact too many applications, except something like Quake or folding.

I don't believe DenBob was comparing the E4300 to the E4400. I believe he was trying to make a comparison between the Allendale and Conroe cores, stating that the Allendales do not OC as high, which for the most part, is the case.
To OP: For your $190 I would say to go with the E6420. Along with your DS3 and a nice heatsink, 3.6GHz is a possibility.

3.2 is possible on stock cooling with the e6420 but 3.6 would require major luck. If you want 3.6 out of the e6420 then you will most likely need to buy a good after market heatsink as well.

The heatsink I plan on getting is the Ultra Xtreme from ThermalRight.

Which of the duo's sit at 3.6?
I haven't gotten my E6400 over 3.648ghz. But I haven't tried. Probably won't try til I get a new power supply. I think it's a question of the amps or something. With a new power supply I could probably do 3.8. With new firmware 3.76. This is according to an actual temperature limit (the CPU itself is not straining at all at 3.68ghz). On ice I have every confidence this CPU could hit 4ghz. It's really a magic chip.
But that's the catch... Anybody can get a bad C2D. I just happened to luck-up. My vcore is 1.225. I can do 3ghz at 1.25. There are people right here on this site that ordered their chips the exact same DAY. It's luck of the draw.

Im loving my e6420 only had it 2 days trying to find a since stable speed . right now im @ 473*8 1.61v . Water is really helping out alot, i can push and bench 3d over 4ghz with 1.7v

<3 my E4300 its a very nice overclock :) im saving money so i can go watercooling :)

1.7v omg ur crazy :p even 1.6 i think is crazy lol but hey 4ghz :D

The e6320 is the cheapest with 4 MB L2 cache.
Nope, found this (http://www.pricefind.co.za/intel/core2duo/computers/processors/intel/socket-775/intel_core_2_duo_e4320_4mb_l2_cache_18_ghz_800_mhz _fsb_1689.htm). looks like a great deal, BTW, 1$ = R7.20.
Given that a 4300 can easily make 3GHz, this looks really interesting.

Can't find those on NewEgg yet.
My 4300 needs 1.525v to get to 3ghz. Can you say dud?

Wow, that's a new one to me, I hadn't even heard of that chip yet. Interesting.

On July 22nd , with the price drop.
What kind of drops are expected and on what items?
Might end up waiting if it is worth it.

It really depends on your batch. Almost all of them of them will hit 3.0Ghz.

Haha, week 44 curses. The funny thing is when I bought my Opteron over a year ago I got a week 0544, and it didn't hit 3 GHz on air but it was still a good oc'er in my mind (2.8). I'm getting 3 GHz in my L644G right now, I don't think that's bad at all.
I think its funny that week 44 in the Opteron and week 44 in the Conroes are both widely reported as being bum overclockers, and even funnier that I have both. It's not that bad of a week. :D

Not to wallow in your misery, but I'm glad it's not just me. I just got my e4300 up and running and, while it's not as bad as yours, it needs 1.425 volts to be prime 95 stable at 3.0 Ghz. I thought I was doing something wrong. Oh well, it can do 2.9 Ghz all day at this voltage (and does :cool: ). I'm happy enough. It plays games just fine and I'm not into competitive benchmarking. It's an excellent chip at ~$114 USD, there's nothing it can't do.

dont know if there are any e6420 duds, mine definatly aint lol...hitting 3.2ghz @ stock voltage with ease :)

I think its pretty subjective, but ive never seen a core2 that once properly set up that didn't overclock decently. Compared to back in the day i feel like every cpu is a winner now as opposed to back when there were "hot" cpus to have, like the 300a celerys and good stepping tbird 1000s and stuff like that, my opteron 165 did a 65% OC on water and this c2d is doing 55% on water.

I'm really leaning towards a E6750 , if I can just wait till July 22nd.
Is the E6750 a big difference from the E6420?

Yeah, as I started pushing mine I had a feeling it wasn't much of an overclocker. I decided to push the chip and my cooling to the limit and this is it. A 67% oc isn't bad at all, but I was hoping for something closer to default vcore :p.

Looks like these initial G0 chips are overclocking like mad. I'd look into the 6x50's:
