Phenom II Overclocking Guide - Page 17

post #161 of 253
i was wondering you guyz keep increasing the voltage and for what again o.O.... performance lol i put my comp into power saver mode like silent mode and still get unbelievable respond rate and also my cpu is very cool im in a 80 F room and my cpu only at 38 C air cooled o.O i still get high benchmark test too clocked at 3.9 ghz voltage at stock didnt even raised a single volt o.O??? saving power and getting ultra performance this is overclocking babe not performance and then a high electricity bill w t f......

Hello everyone,

I've been building my own machines for about 15 years now but have just recently decided to try overclocking. My last mobo died on me so I bought a replacement CPU/board combo. Please critique my OC so far and let me know what I can do to improve it. Most of the system is about 3 years old so it's not top of the line.

System:
GIGABYTE GA-MA785GM Motherboard
AMD Phenom II x2 550 Callisto CPU
CORSAIR CMPSU-650TX 650W Power Supply
RADEON HD3870 512MB Video Card
CORSAIR XMS 4GB DDR2 800MHZ RAM
Western Digital Raptor 10k RPM HDD

Overclock:
The first thing I did was unlock the 3rd and 4th cores of the Phenom. It was easy enough, took me about 10 minutes to do. the CPU isn't a black edition so I can't adjust the multiplier. I have taken the clock to 240 (3.7Ghz) on stock power and Prime95 blend for about 10 hours. Pushing past that I have to adjust the Vcore. Taking it to 245 (3.8Ghz) and 250 (3.875Ghz) with Vcore at 1.375 and 1.4 respectively, runs stable on Prime95 blend for over an hour. the system didn't crash at this point, I decided to push it further. I haven't ran Prime95 overnight on these settings yet but plan to tonight. My temps are a bit high with the cooler I have so I've ordered a CORSAIR H50. With what I have now on full load I am hitting about 61c.

Questions:
How much further can I safely push the Vcore.
What max temp should I stay under (I want to try to keep it at about 50-55c)
After I hit the max on the CPU what is next? What can I do with RAM, Graphics...

Alot of people say 1.45 volts is the max you should run, i've had mine @ 1.5 for about 9 months almost and never missed a beat, even pushed 1.65 through it at times when beanchmarking.

With the volt vurus clock speed there is no reason you cant get 4-4.1 stable with 1.5 volts. The main thing is keep the chip cool, and with a H50 you'll be able to keep it below 50 in theory. Even with 1.6 volts I keep my sig rig below 45 deg 95 percent of the time.

You mention ocing your ram, unless you've reduced the multiplier for your ram you already have it over clocked to about 960mhz, your ram is effected when you change the clock.

If what you've done so far is with the stock cooler you'll be able to hit 4.1 with ease once you have a better cooling system.

Good luck

Hey. Yes for a beginner its ok to just up the multiplier. Remember to test for stability and please check ur temps. @ some point Ull have to up the cpu voltage.

Let us know

Your OC looks great Maximous, I like the high NB clocks. Everything looks great as long as the temps are good.

Also thanks for helping out in here while I'm busy this summer .
