Contagion

cool. thnx man
i just passed my first stress test with it at 3.5ghz
1.38 volts in cpu-z
thats with 1.2 with .2 overvolt

Contagion, some users have had success with overclocking to 3.6-3.7Ghz with stock voltage. As soon as you run into stability issues with the overclock then that is obviously when you know you can't go any further. Always run stability tests to make sure the system is stable. If you haven't already, check out this Phenom II overclocking guide. It's extremely helpful and explains a lot of things: http://www.overclock.net/amd-general...ing-guide.html.

Good luck

Here are my very preliminary results: Haven't played with the settings yet, only took a few minutes to boot into 7 and run a benchmark before work. Will tweak voltage, remove CnQ, etc and see if it's prime stable tonight. I am hopeful for decent results, my score went from 6.5 to 7.3 for CPU so there is at least SOME gain to be had. Will post results later.

thlnker... I have been able to pass stability tests at 3.6ghz w/o a voltage increase. My prolem was when I raised the NB to 2800mhz and gave the NB vid a +275 voltage bump. Then it failed the Everest stability test immediately.

Please answer me this one question. Shouldn't my scores in Everest be allot better with 4 cores then with just 2? My benchmark scores are actually a little worse with 4 cores then they are with 2. I can pass the stability test @ 3.6ghz w/o a Voltage increase with all 4 cores unlocked. On the other hand my scores are no better with 4 cores then they are with 2? Plus I'm still mystified with the Athlon X2 6400+ scores so much higher.

Thanks for your Input!

An hour into Prime on the intensive setting not a problem. Rock stable stock x 4, temps max at 45C. If it runs fine for tonight, I'll see if I can't get that voltage down I believe it's sitting at 1.328 right now, I'd like to hit 1.2-1.25 ideally. Don't need to overclock.

RendoR, I'm not surprised. 2800Mhz is pretty high for the NB Frequency. I have feeling not even a voltage bump will add stability. For your processor 2800Mhz might be the limit on the NB Frequency.

It really depends how Everest was written/coded. Perhaps the application is not taking full advantage of all the cores during benching? That could be one culprit. Which benchmark test are you running again?

Staryoshi, how does everything feel at the keyboard level with an 800Mhz quad-core? Do applications feel the same when you go to open them up? I like that super low voltage and full load temp

Good luck

I didn't play with it much when I had CnQ enabled, forgot to disable it before I unlocked the cores :P It was as responsive as it should be, and clocked up very quickly when called upon. Here's what things looked like after an hour of prime (This manuever has rendered the individual core temps non-functional, but having the overall temp is enough for me... especially when they're this nice):


Unfortunately I didn't make a dual core baseline to compare against, and I haven't had an opportunity to run other multi-core benches to determine its true effectiveness, but regardless I'm extremely impressed with this CPU. I ran through the cpu tests in Everest and it placed this CPU just barely ahead of the PII X4 940, just as it should (100mhz diff). Using a scythe katana 3 in a 79F (26C) room, i'm idling around 30C and you can see the load temp there... I'm really impressed beyond words so far 3.1Ghz "Quad" core cpu for $97... (Even if its functionality is diminished, I have seen signs that it offers improvement, such as my Win Exp Rating going up (CPU 6.5 to 7.3). This HD4830 is no slouch either.

This setup is of course a much less powerful gamer than my main rig, but I'm having a blast with it Considering selling that rig and upgrading when P55 hits... keeping this one for a few months as mah main. Tomorrow I'm going to tackle the voltage and see if I can't get it runnin' even cooler.

I wonder if my RAM is having a negative effect? I have 4gb installed with 32 bit XP. Only 3.25 is registered. If I took one stick out could my benchmarks would improve? Either that or I could take the Kingston HyperX out and install the Corsair Dominators. They require less volts at 5.5.5.15 ( 2.1v vs 2.2v ) I just have to trim about 4mm off the heat sinks first to clear the cooler.

I read somewhere that 4gb is not recommended for 32bit because of the RAM on the Video card. More RAM then the system can use and no head room.

thlnk3r

RendoR, typically this is recommended if you're running more than two sticks of memory. This will usually put a substantial amount of stress on the IMC (integrated memory controller) which in turn can be a problem when start overclocking. Some users however have had great luck with running four DIMMs. Honestly I think your fine. It wouldn't hurt though to test the other memory you have. If you're really wanting to run 4GB 24/7 then I recommend picking up a 64-bit operating system.

Good luck
