Overclocking Core 2 Duo with slow RAM

[Money]

get a better cooler before u melt it LOL

My E6420 is running at 3.2GHz now with stock cooling and voltage.

I've run prime95 with 100% load on both cores for a couple of hours for temperature purposes, max temp was 58C. I'm now re-running prime95 to test for stability going to let it run for about 12 hours.

ok, my e6600 is stable @3.4ghz @1.475 vcore
using this cooler:

ran a stress test for 5.5 hrs and no error max temp was 63C

this is my cooler, buy it it fucking rocks, its only on a sempron 3100+ and is ICE cold

well in MY experience, it hasnt shortened any of my processors, seeing i still have an old 500mhz celeron that is from 1998 overclocked to 820mhz which is at my inlaws running strong..so yea

not always, more than likely if u dont buy a better hsf...yea

Yes, always.

This is based upon experience in designing, developing and manufacturing electronics, including motherboards, for the last 20 years. Simply put, over-clocking runs the part beyond it's specifications, particularly it's thermal specs. This voids the warranty and puts the part, and components around it, at risk.
I have had this discussion many times with Intel and AMD AFE’s, over-clocking any CPU will shorten it’s life expectancy and decrease it’s MTBF.

get a better cooler?

better thermal compound is also a good idea if youve got some generic silicone based paste.

i got am e6600 last week. oc'ed to 3.4ghz. (8x 425) (OCZ Sli ram underclocked to 850mhz)
(I tried 3.6ghz but it was either unstable couldnt boot and running a lil too hot.)
idle @ 39-42c and load at 55-59C
my voltage is 1.45 i think.
any suggestion to make it run cooler? i already got a aftermarket cooler
maybe i should lower the voltage a lil bit

overclocking = shorter processor life

e4300 is an overclocking monster

[Ewan]

I probably should have updated. Got an E6420 and 800MHz RAM in the end. Got those bits but not the rest yet, I put in the wrong post code so it all got returned and am still waiting for the refund to process.

If you want to overclock your ram, I strongly getting ram which uses the Micron D9GMH chips because those are the ones that are the most overclock-friendly (Micron D9 Chips can easily overclock up to 30% or more). My preferred brand of ram is "Crucial" since they use Micron D9s in their Ballistix line of ram (newegg has some deals on these such as on the PC2-8000 and PC2-8500 models).

As for overclocking with slow ram... if you don't want to get faster ram, you could get the e4300 instead of the e6400. The main advantage would be that the e4300 has a higher multiplier (9x instead of 8x), so you would be able to overclock without needing to increase the FSB as much (therefore slow ram would be fine). Of course the e4300 does have some inherent disadvantages compared to the e6400 and e6420 such as lower L2 cache and no virtualization, but if you mainly care about overclocking and dont want to get better ram, e4300 is the easiest one to overclock.

If you want to overclock your processor I would recommend you get an aftermarket heatsink/fan since the stock intel one is fairly lackluster. I am using the Freezer 7 Pro (which for some reason newegg is overcharging for, best deal is here (same place i got it from): http://www.ewiz.com/detail.php?name=FAN-AC7PRO). I have an e6300 (1.86ghz) overclocked to 3.0ghz on stock voltage and my cpu temperature is around 32 degrees C at idle, which is quite nice!

ddr 800 ftw.

Update, I am definitely going to return my Processor when it arrives and buy the E6420. I am probably, but not definitely going to also return the RAM and buy the faster RAM, it's only 30 quid more, I just need to consider if it is worth it or not.
