used E7500 for O/Cing, should i?

[Borealis7]

i'm looking to get a little more out of my 775 rig. currently i'm running my old E6550 (65nm,4MB Cache) at 2.8GHz (400x7) using 2x1+2x2 RAM sticks (total 6GB @ 1.9V) under a CM Hyper 212 (not "+", the older version). idle temps are very good around 24 and load doesnt exceed 55-57.

now, the E7500 is a 45nm 3MB Cache 11x multi CPU. i know plenty of people have had good experiences O/Cing these babies, and i'm wondering if its worth it for me to get one for about around 70$ used. my goal is 3.7-3.8GHz, preferably 4GHz

its highly o/cable and cooler running than my current CPU, but has less cache and O/C is never guaranteed. i would've gone for an E8xxx but where i live they cost alot more, upto 3 times as much.

looking at AT Bench, a Stock E7500 is about equal to my current CPU. i'm not considering Nehalem for now because i'd like to keep my DDR2 RAM, plus i hear LGA1156 and 1366 are dead sockets

i mainly play games on my computer and do light multi-threaded programming in JAVA.

should i do it? are OCed E7500s very hot at load? what about voltage and power consumption?

What do you expect out of a $70 investment? The way I see it, any gains you get (potentially higher clocks/performance, potentially lower temperatures/power draw) are going to be very marginal. Now, of course you can sell your old proc to offset costs, so that might make it closer to being worthwhile. Additionally, maybe you're just itching to try it, in which case GO FOR IT!

I'd personally aim a bit higher such as E8200+ (for 6MB cache) or a quad core.

I recently upgraded my 65nm e4300 in a server to a 45nm e5400 (like yours just 2MB cache and lower fsb)
the e4300 was running at 3GHz oc'd
the e5400 runs at 3.6GHz with the same motherboard and modest cooling (zalman).
Total system power usage is about the same or slightly lower at these speeds (185 watts w/ 9800GT). Overall it was a good upgrade, I just couldn't justify spending the $ for a quad.

Can you get a 7200 or something for less? 70 is a lot for this "upgrade" consider you can get a used Q6600 for 110.

i'm not in the US, prices aren't the same here.

i think i'm going to resist the urge and pass. wait for socket 1155 chips and consider my options. also, it looks like the only way i'll be able to keep my 6GB DDR2 RAM is to go AMD but i want a fast dual/quad chip for gaming and not a slow many-core CPU...

You can hit 4 ghz easy with average cooling and good motherboard. It's night and day difference for me from say 3.0 to 4.0 specially with my 5850 but you also may be better off waiting.

yes, do it.

Mine runs happily at 3.6 Ghz on default v core...
Bump the fsb to 1333 Mhz, leave the memory freq at a safe level, bump the vcore a notch and finally test stability using IBT...
Presto, you're done...

why not use 400FSB? does your memory not run at 400MHz?

Yeah I would go right to 400 just set your memory to the right divider. Knock down the multiplier so your in noramal speed range then start bumping it back up to test higher speeds while raising voltage.
