Phenom II X4 965 BE @ 4.08GHz, voltages ok?

post #1 of 15
Thread Starter 
I've been tweaking this setup for quite some time, basically since I built the computer back in February. I've already managed to do many things I never imagined I would be able to, but was wondering if anyone has any other suggestions for improving the setup, or if I'm sitting pretty, which I expect I may be at this point. I'm always learning though so I want to see what everyone thinks and what your suggestions may be.

So, here is my current setup:

AMD Phenom II X4 965 Black Edition CPU (3.4GHz)
ASUS M4A79XTD EVO Crossfire Ready motherboard
4GB (2x2GB) of G.Skill Ripjaws X DDR3 1333MHz RAM, 7-7-7-21 2t, 1.5v
Nvidia GTX 460 1GB (reference card, MF'd by Nvidia), 675MHz core/900MHz mem (3.6GHz effective)

CPUID Validation: http://valid.canardpc.com/show_oc.php?id=1962422

My current CPU settings are:

Running Speed: 4080MHz
Bus speed: 240MHz
Multiplier: x17
CPU-NB: 2400MHz (x10 multi)
VCore: 1.4875v
CPU-NB volts: Auto
CPU VDDA volts: Auto

Cool N Quiet Enabled

HT Link Speed: 2400MHz (x10 multi)
HT Link Width: 16 bit
HT Link Volts: Auto

RAM settings are:

DRAM Frequency: 1600MHz
Timings: 7-8-7-21 CR 31 2t
DRAM Voltage: 1.64v

GPU settings are:

Core voltage (after BIOS and voltage mod): 1.187mV
Core Speed: 920MHz
Shader Speed: 1840MHz
Memory Speed: 1050MHz (4.2GHz effective)


My temps are fairly well in line and Intel Burn Test/Prime 95 can both run without errors or crashes. My CPU idles at 25-28 C and during average use it hangs around the mid 30's. While gaming it spikes up to 50 C for short periods but generally stays around 45-48 C, and only when stress-testing does it cross the 50 C threshold, spiking up as high as 59 C with Intel Burn Test and 56 C with Prime 95. Both tend to average lower than that though, and hover between 52-55 C most of the time, measured with Core Temp. Are these temps OK? I know they're on the high side, but is there any danger, considering that I've tailored my overclock to allow for Cool N Quiet to continue working properly? It only hits high temps like that for short periods at a time.

My GPU does OK temp-wise, although it now runs MUCH hotter than it did at stock settings. I had to compensate by setting a manual fan profile to keep the fan idling at 60% and maxing out at 100% if the temp reaches 75 C. It only gets that hot when I run Furmark or Unigine Heaven Benchmark; generally it hits the mid to high 60's while playing intensive DX11 games.

Any input you guys have would be much appreciated.

ya cpu temps are ok , i think the max is 63c , i would turn Cool N Quiet off for stability

I like the low temps it brings, but I can understand why it might help to disable it. It down clocks to some pretty weird frequencies with this overclock and seems to run a bit smoother with it off. Thanks for the suggestion I didn't even think about that being a factor in maintaining stability.

Temps with CNQ disabled are the same at load but idle is now ~33-35 C. I cleaned my PC and reapplied thermal paste to my CPU/heatsink yesterday evening, so I expect both load and idle temps to drop by a couple more degrees in the next day or so.

Nice one there mista. U should also lower Ur HT down to stock(or the closest value). No performance gain with a higher HT. Actually it can hurt performance.

Temps looking ok, bit higg at 59 but if Ur stable why not.

One more thing. I would never use furmark for testing stability. Puts just to much pressure on the gpus. Use gputool or atitool.

Everything looks good and your temps are great. As Maximous said Try to decrease the HT to 2000 having it higher than that actually hinders performance.

Thanks guys. What do you suggest I set it to? I believe the only values available due to the Bus speed are 2160 and 1920. Which would be better in this case? I know that 1920 is closer to 2000 than 2160 but would underclocking it hurt performance just as much as overclocking it, or less? And does the fact that I have a motherboard supporting up to 2600MHz HT Link change anything (says it right on the box in like four places and it's stamped on the motherboard too)?

1920 is what I would go with, only because I know mine craps out over 2160. Here's mine.

Have you tried lower VCore? I know all CPUs behave different, but there is a good chance that you can get that OC with less voltage than what you're pushing right now... My temps are not quite as good as yours, but then again, I am in Florida and it's summer time.

Haha nope, my CPU is incredibly voltage hungry, I get BSOD's constantly while stress testing up until about 1.4625v, and at that voltage I have an extreme vdroop under load (drops down to 1.446v under load and goes as high as 1.49v at idle). I'm testing it at 1.4625v right now, and have updated a couple of settings, but I don't know if I will be keeping it here permanently; it all depends on the results:

CPU Settings are:

Running Speed: 4080MHz
Bus speed: 240MHz
Multiplier: x17
CPU-NB: 2640MHz (x11 multi, up from 2400MHz)
VCore: 1.4625v (down from 1.4875v)
CPU-NB volts: 1.2875v (auto setting led to crashes)
CPU VDDA volts: 2.60v ({poor} compensation for vdroop)

Cool N Quiet Disabled
ACC Enabled, +4% (whatever that does is beyond me, but it's been suggested on a few forums)

HT Link Speed: 1920MHz (x8 multi, down from 2400MHz)
HT Link Width: 16 bit
HT Link Volts: Auto

RAM settings are the same, I know that the RAM is 100% stable at it's current overclock.

Anyway, I'm getting ready to run 10 passes of Intel Burn Test, and if it passes, an overnight Prime95 Blend Test. If stable, I will keep everything where it's at and call it good; been f***ing with this for way too long.
