Safe voltage settings for Amd Phenom II X4 945
Safe voltage settings for Amd Phenom II X4 945
Hello, I also own the 945 deneb 3.0 and it's currently overclocked to 3.3 with a stock heatsink. I reached 3.37 after a restart, but no blue screen appeared when playing Bad Company 2. The voltage was around 1.62 or slightly higher. Was more voltage required or could better cooling help? I'm considering using Arctic Silver CPU paste—would that bring me to 3.4, or would an aftermarket cooler be necessary? Any advice on aftermarket heatsink and fan brands would be appreciated. Thanks!
It seems like you're overheating as well. Also, the voltage of 1.65 is quite high for a 300MHz overclock—AMD recommends a maximum of 1.5, and staying well below that could prevent blue screens. I’d suggest lowering it to around 1.4 and using an aftermarket cooler would help.
at 1.6 you should aim for around 4.1 or 4.2, reduce the voltage and get a solid heatsink based on your RAM and case. choose one that fits—like the 212+ or core contact freezer, but if your case is thin, opt for something such as a Thermaltake Max Orb, which works well and has a lower profile.
I didn't interpret the voltage properly... right now it's 1.3 with the CPU at 3.3. No issues have occurred yet.
The multipliers are fixed because it's not the black edition, so I need to increase the CPU bus frequency to overclock...it automatically clocks the memory, right? Does this also raise the voltage if auto is enabled? I set the voltage in my BIOS to 1.425 and entered cpuz, which shows 1.1??? But I mentioned it's stable at 3.3 and 1.3V. I’m hoping an aftermarket cooler can help push it higher. Can someone clarify the voltage situation?
Do you know the reason behind your CPU voltage not reaching over 1.3V? If you set it higher in BIOS, it comes back lower than 1.3 when auto is enabled. In AMD overdrive, the voltage reaches its maximum at 1.3 for this CPU model... Is this limitation due to it not being the premium version? You have the AMD 945 3.0 Deneb 95W.
I'm testing the same CPU right now. I have an ASUS board with the latest BIOS, dual 2x2 RipJaws RAM paired with a Zalman 9900 cooler. I'm running 3.6 with overvoltage at 1.46. Temperatures stay below 40. With the original heatsink I could reach 3.4 but it got quite hot around 59°C. An aftermarket cooler would make a big difference! My FSB is 240, HDD/SSD count is 2160, downclocked RAM to 1280 timings at 9-9-9-24 (may vary with different memory types), and voltage set to 1.5. It's stable on Prime95. Hope this helps! Oh CPU says it's at 1.41, Everest says 1.44
I'm using G.skill 1333 ddr3 downclocked to 1178 with timings at 8, CPU voltage at 3.3V and voltage at 1.3V. My FSB is 220, nb speed is 2200. Why is my nb higher than yours when you're at 3.6 while I'm at 3.3? Also, when I raise the voltage in my BIOS above 1.3, it lowers the clocked voltage. I suspect there might be a faulty board—everything else seems normal, even with AMD overdrive, the max I can set is 1.3V and boosting the OV meter just resets it.
