overclocking phenom ii 550 be stock 3.1

jonnyp1993 · 10 Jul 2013 at 08:50

Hi guys. I dont know much about overclocking but know some basics.
I have my 550 at 3.3 with multipler at 16.5 and voltage at 1.139. Stock settings was 15.5 and 1.135v.
If i take the multi upto 17 - 3.4 or 17.5 - 3.5, i get bsod. Do i need more voltage? How far can i take it ?

Im using stock cooler at the min but i am upgrading to a new one shortly.
My idle temp at the min is 40c and under load with prime95 it reached 57c even in this british sunshine!

Does cool n quite have anything todo with why im bsod ?

Any tips would be great

You will probably need a little more voltage, try increasing it in 0.20 V increments till you get stable.

Your CPU's voltage range is 0.850-1.425V, so make sure you don't exceed that.

I would also have Cool n Quiet disabled if it were me.

My guess is you can get your multiplier to 17-18-19 if you start increasing your voltages into the area of 1.25

Ok i will try it when i get home. How far do you think i can take it on stock cooler ?

You can probably get away with a little bit more, but it will probably struggle the higher you push it. Just keep monitoring it as you progress and make a decision depending on what results it gives you.

Personally I wouldn't take it past 45 degrees on stock.

Ok. I should be getting my new cooler this week. Havnt decided which one yet though

You going with a better air cooler or some form of watercooling?

I was thinking of gettingna h80 but reliability has made want a decent air cooler.
Id love to custom loop it but cant afford that just yet.

What's wrong with the H80's reliability? I've been running a H70 for pretty much 2 years now on quite a strong overclock and it hasn't skipped a beat.

I would say, unless you have a case that is built well towards air cooling then I would go with a corsair WC kit, can't really go wrong imo

2 friendsnof mine have had them and both pumps went. Theybhad them replaced then 6 months later they went again so they havebgone back to air cooling.

My case is great for air cooling. It has 1 120mm on rear, 2 200mm on top, 3 120 on front and side for intake. Also has a 200mm on side aswell.

Stock voltage of my phenom II x4 955 (3.2GHz) is 1.35V and I've had my voltage up as high as 1.6V to push just past 4.1GHz.

You will not want to be pushing these voltages on the stock cooler. I have run mine at 1.46V for 4 years which gave me just shy of 3.8GHz. This ran at a maximum temperature of 60 degrees using a megahalems. (it now runs at 53 with custom water cooling)

Cool n quiet is unlikely to be the cause of your issues. I run cool n quiet on my system and it's been stable plus it runs cooler and uses less power whilst idle. Just make sure to check if C1E is enabled. If it is check your dpc latency as this feature made mine very fluctuate massively.

I was looking at a megahalems cooler ealier, are they good ?
Whats c1e and dpc ? I said i only know basics lol and i means it

Thank you.

C1E is a power saving state and should be an option somewhere in the bios.

Dpc latency stands for deferred procedure call. (full explanation here) High latencies affect the computer's ability to stream and playback audio in realtime.

Yes the megahalems was a good cooler. I only upgraded to watercooling for my graphics card.

Ok, I'll have alook later, and good, I think I'll be getting one
