Which model of C2D to buy for Ocing

[epexy]

Hi.

I want to change my E4300 that i had it working at (320 x 8) with the stock cooler for months.

Now I'm between:

E5300 (200 x 13 - Rev- R0) - $100
E7200 (266 x 9.5 - Rev. M0) - $155
E7400 (266 x 10.5 - Rev. R0) - $165
E7500 (266 x 11 - Rev. R0) - $172
E8400 (333 x 9.0 - Rev C0) - $225

(prices from my Country, sux)

I have an ASUS P5B Deluxe and 4gb of 800 mhz RAM (4-4-4-12) Kingston.

Basically I want to know which one will overclock the best with a stock cooler, and by this I dont mean which one will yield the highest speed but the highest difference between the stock speed and the overclocked speed.

I'm leaning for the 7400, since the 8400 is kinda expensive for what im looking for and the e5300 is too similar to the e4300 that I used to have. but I may be wrong.

What do you guys think? Which one should be better considering price and performance.

E7500 (266 x 11 - Rev. R0) - $172

That'd be my choice, because of the lower frecuency and higher multiplier, it can overclock higher (just in %, not final GHZ), 25% OC in that cpu is nothing.

but keep in mind that one of the best cpus for OC is the E8400. but you might need a new heatsink to get it close to its full potential

Agree with the above post.
E7500 and E7600 are best value for money OCs, but E8400 E8500 E8600 will yield in higher numbers.

E8500 is a small price jump up from E8400, but E8600 is silly priced (although I want one so bad 🙁 ).

Out of your list, I'd go E8400. Easy 3.6-4Ghz.

My E8400 runs at 3.6 ghz with the voltage dropped to 1.14V. I can run 3.9ghz with it set to auto (1.25v) The big thing is the heat. With the heatsink it came with, it would clock down because it would get so hot. (over 73C under full load) Even undervolted and the artic freezer pro it still idles at 39C-42C and when it's fully loaded it's around 58C. Don't forget though, every chip is different.
One thing you might want to consider is the AMD 720 BE. It's only 120 bucks and has an extra core. I have mine running at 3.6Ghz but I had to go high on the voltage, (1.52V) but it runs cooler than the E8400.

Oh yeah, if overclocking, do not use factory heatsink and.or compound.
My E8500 @ 4.37 peaks at 65C (for like 1 second rare but happens) but normally 38C idle 60-62C load (Prime95 SmallFFT 3 hours)

Thermal Spec is 72.4 which is for Tcase, coretemp is roughly +5, so anything under 77C is fine.
My old P4 spent 2 years at 80C without throttling, probably wasn't good for it, but its 3 years old now and still did an easy 15% overclock, no damage to be seen. Its not in use now because its too old and the Asus (grr) motherboard died.

e7500 is good
i have it runing with my P35 m/b with latest BIOS
at 333*11 with stock cpu cooler without adding any Vcore volt
im getting a new cooler CM hyper 212 plus
i think i can get it runing some where around 4Ghz ( i saw ppl did it easily )

Wait for the e6500k hands down with out a question. Sub 100.00 cpu with an unlocked multiplier.

 

[SpidersWeb]

Just looked that up.
Has less cache, when it hits stores here I'll buy one, see if I can do 5Ghz, and if it's faster than the E8500 at 4.37. Looks like a lot of fun, seen it's already done over 5Ghz at 1.72V.

Edit: I'm not seeing Core2, I think its just a 45nm Pentium Dual Core, don't think it does HT or anything, will overclock well but performance might be questionable. Explains the price tag.

 

[sportsfanboy]

It's a Wolfdale core with less cache

I read somewhere that they will sell for around 80.00 USD, for that price I'm thinking about grabbing one just to see how long a really high overclocked chip will last.

try to get the E8400 at the EO stepping instead of the C0 stepping.

 

[mahmoudi]

I got an i7 920 but if i was going to buy a c2d i think E8400 is the best option

 

[stumpystumped]

I don't see E6300 on your list. That's basically a Core 2 Duo, overclocks very well, I got mine running at 3.5Ghz from 2.8Ghz at 1.15V (after vdroop) that's lower than stock voltage.

get dual core E6300(266x10.5), its best value for money now a days and it runs very cool with new R0 stepping and can easily reach 3.8GHZ on stock HSF.

Hello, OP here.

After reading all your helpful comments, I decided to go and try to get the E6300 as the last couple of posts suggested. Well, for some reason nobody sells that cpu around here, couldnt find it at all. So I went and grabbed the E7500 which seems to be a little better with that extra mb of cache.

Should be here first days of next week and I'll let you all know how it turned out.

Thanks everybody for the halp and suggestions.
