E6420+P5NE-SLI (Safe overclock with Stock Fan?)

post #1 of 10
Thread Starter 
Hello to all, I.m new to overclocking and to this forum, I´ve been reading for the past 2 weeks, many post in this forum, but I couldn't find or determine a possible answer to this question.

What would be a safe overclock for a E6420+P5NE-SLI using Stock intel fan?
Could it reach a 1:1 ratio with 800 mhz DDR2 memory? (8x400mhz=3200mhz)


I.m new new to overclocloking, all I have is the theory after reading around 100 post in this forum , and I.m planning to buy that C2D and mother.

Thanx in advance for any feedback ,

Actually Cyph3r, that's about what I get too on the stock fan. Well, maybe both our chips suck.

I think 3.2 would be too hot with stock

I'd recommend around 2.6 to 2.8 MAX and watch temps

How can you say 3.13ghz on stock fan is crap? Thats a 1ghz OC on stock. Did you watch the temps when you all did that? I could only get mine to 2.8ghz on stock fan before temps got pretty hot (around 60C). I wouldnt consider that crap since they came 2.13ghz stock.

I should have scrolled down a little bit further, but I just posted a similar thread. I just oc'd a friends 6420 today and couldn't get it over 2.6 with stock voltage and cooling. I recommend using a program called TAT to stress the system and watch temps if you over clock. My readings said to not let it get over 60 degrees. I let the program run for about 20 seconds at 3.2 ghz and it was around 65 degrees, so I say that's out of the question, unless you can under power it as someone has suggested to me. He was running around 1.26 volts at like 3.1ghz I believe. If you wanna oc, as I would on my own, I suggest getting some upgraded cooling when you buy, as it will allow you about another 1ghz of speed

I have the same motherboard and CPU combo as you, Anpuebla, and I'll tell you that the P5N-E SLi very gladly yields amazing E6420 OCing. The only obvious limitation is temperature.

Legion Hardware has pulled off 3.5 GHz on the stock Intel HSF with the P5N-E SLi. I was skeptical of this, so I bought another separate cooler just to be safe.

I have this HSF at Newegg for only $29 after rebate, free shipping. I have my E6420 at 3.5 GHz and it idles at 44C, never seems to cross 50C mark. Absolutely silent. Just figured I'd tell you this amazing bargain out there.

At first I was hoping to use the stock Intel cooler too, but it looks like Intel only packed hefty overclocking coolers with their faster CPUs.
