The Phenom II List of Overclocks

[Throwed]

I am a tad pissed off now. The Phenom II 940 is only 235 now. The Phenom II 920 is 195. Well, I guess I can't really complain when I got mine so cheap.

I sure as hell didn't get it cheap...

yea i saw that didn't they say earlier that it would drop to 225? anyway its a nice drop just after the chip was released and maybe we will see more when am3 comes out but im not counting on it anymore. also i thought this phenom II 940 review was funny: another person saying their tech level is high.

Pros: Played a week with this chip and best (everyday practical use) I got is 3.4GHz stable (64-bit Prime, OCCT, etc...) using 64-bit Vista ultimate. NorthBridge multiplier 10x, NB volts 1.325V. CPU Vcore 1.4375V, CPU multi 15X and HTT 226MHz. Memory at 800 (not 1066). Temps at full CPU load around 56C using Antec Sonata III case (case fan at middle speed setting) and Xigmatek HDT-S1284EE heatsink.

Cons: Could not get 2x 2GB Kingston HyperX (PC8500 5-5-5-15) work completely stable at rated speed. Newest motherboard BIOS (0802) helped a bit, but still random BSOD's... using 1066 memory speed also increased CPU temps by couple degrees and reduced highest stable CPU overclock to 3.3GHz.

Stock heatsink run 10C hotter than the Xigmatek. It is only good enough for the CPU at stock speed/voltages... Don't expect to overclock with it!

Other Thoughts: Seeing all those report people reaching almost 4GHz stable (really?) with air cooling... I'm sceptical. I tried my best and didn't get even close! What gives? Worse than average chip???

Using Kill-a-Watt power meter the setup below use 175W at idle (no Cool'n'quiet) and 274W at full CPU load (Prime) With Prime and 3DMark running together peak I noticed was 340W.

My rig:
64-bit Win Vista Ultimate
ASUS M3A78-T
Phenom II 940 (0849APMW)
Antec Sonata III with 500W Earthwatts PSU
2X2GB Kingston HyperX 1066 (5-5-5-15, 2.2V) @ 904 5-4-4-12-15, 1.9V
Sapphire Radeon HD4870 1GB (810/1000)
WD Raptor 74GB for system
WD 750GB for data
3DMark06: 15900

Heh! New xtremesystems member here. Took only 2.5 weeks to get access to this forum...

It was me who did you quote on the Newegg Phenom 940 review. That PC and CPU I no longer have. (It was a build I custom made to a friend.)

After that I build a new PC for myself using PII 940 (0850DPMW) and Gigabyte mobo and got 3.5GHz overclock at stock voltage. 3.6 is stable with 1.40V. Also the Kingston HyperX PC8500 RAM I can run at 1066 speed, while with the earlier build it was not stable, no matter what timings, DIMM voltages or CPU NB voltages I tried. What do you think, was the earlier MoBo bad? (It was ASUS M3A78-T. Afterwards I did read that this particular type has terrible Vcore droop... that certainly is not helping when overclocking.)

TIP: I had slight memory stability issues with this build too, but once I increased the CPU-NB voltage by 0.1 those are solved. NB is currently clocked at 2.4GHz.

I told to my friend about my success with my build and we agreed to RMA his CPU. It was just sent out today.. so it will take a while to get the replacement. Hopefully the new one is better... at least the memory should be stable at PC8500 speed.

At the moment I'm very happy with my new PC. It is now idling at 3.5GHz and consumes 95W from the wall... I don't have yet a videocard, so I use the built in video. At full CPU load (Prime, OCCT,...) the wattmeter show 195W peak. If I downclock the CPU to 800MHz and put Vcore to 0.8V the wattmeter show 70W. So at best the Cool'n'quiet can save ~20W in power at idle... which is neglible to be bothered with, in my opinion. (Especially when it makes overclocking impossible, unless just by increasing HTT clock.)

well, here is my 3.8ghz PI 32M run in Windows 7 32bit

Hows windows 7 running this cpu, any difference in overclocks?

I have had no issues getting OC's in this OS. Both 32 and 64 seem the same. I can boot right into both 32 and 64 @ 4ghz 1.45v. it is not OCCT or Prime Stable at the voltage, but I can run IE and games with no problems.

would be really nice if 64 bit and 32 bit would oc to the same speeds. so you wouldn't have the frequency loss when moving to 64 bit.

Your cpu will error out "behind the scenes" though and could cause OS or file system corruption. It's best to atleast be OCCT stable. Any less and with prolonged use you're asking for trouble.
