AMD phenom ii x4 965 overclock unstable

[Victini517]

The problem is that i can't get 3.9ghz even with 1.5volts. I know 1.5 is just in the safezone for voltage. Everytime i go over 3.8ghz it bluescreens on the desktop.

Why not just OC it less?

1.5 is too high, drop it down to 1.4 max.

Naw, 1.5 is fine for those phenoms, it just needs to stay under 60c in prime 95, which is surprisingly easy to do, even with a 120 mm air cooler. Also, 1.425 is the stock load voltage...so no 1.4 isn’t max.

Surely you can't be serious... Surely...

Just don’t go past 3.8 or go higher on voltage barring the ramifications, there really is nothing else you can do, your chip is a bad bin and that’s kinda just something you’re stuck with

Phenom II's could only reach 3.8GHz ~ 4.0 GHz range.

If you are unlucky, you could be as low as 3.6 GHz.

 

Bringing back the old memories from my brain's archives (from when I had a Phenom II X4 955 Rev C3, and a Phenom II X5 1090T)

• What is your CPU-NB frequency and voltage are you running (you need to increase the CPU-NB voltage as you go up in CPU overclock)?
• Have you tweaked the NB and SB voltages (in higher overclock situations, increasing these VERY slightly can help with stability)
• Does your motherboard have Load-Line Calibration settings?
• 1.5V Core Voltage is on the higher side of things, but still within the safe limit range.

 

Recommend to stay 1.5V or below, especially if you have a weaker motherboard, or not a good cooling.
