Any Phenom II Owners Here?

[sangyup81]

Got an x2 550 unlocked to x4 B50 that has been running stable at ~3,5ghz since release. pretty happy with the bang for buck on that one not tried doing anything with voltage though, maybe it'll go higher?

That's an excellent unlock and overclock for stock voltages. You should overclock the CPU-NB a bit so you aren't bottlenecked by the memory controller and L3 speeds.

If I may step in guys. I am overclocking my Phenom II BE 940, I am at 3.4GHZ and now I would like to OC the NB too, should I just it from auto to 12x or even 13x and raise the voltage to 1.2v?

Thanks

Here's my Phenom II X2 560 unlocked to X4 B60 setup according to the numbers I get in CPU-Z

CPU: 207.7 MHz x 19 = 3946.3 MHz, 1.512V (load), set to 1.6125V in BIOS
CPU-NB: 207.7 MHz x 14 = 2907.8 MHz. I don't get any CPU-NB voltage measurements in Windows but it's set to 1.55V in BIOS.
HTT: 207.7MHz x 9 = 1869.3 MHz (according to benches, you do not want HTT too high over the stock 2000 MHz )

An important thing to note is that I have LLC off for both CPU and CPU-NB voltages and a Corsair H50 with 2 fans cooling this CPU. This is the only reason I can set the voltages so high in BIOS. If the CPU temps ever get to 62 C, stop what you are doing and slow things down.

This is all done using an ASUS M4A89GTD Pro/USB3. As always, YRMV

I ran this thing at 4.2GHz for a few benchmark runs... but did a quick bench to post this. Phenom II 555 -> B55

ok here sorry for any mixup

A noob question;

Does a stock Phenom x4 965BE become a bottleneck for the AMD 6870 gpu? Or is it powerful enough?

 

[crisium]

That'd be fine. We have people here running Crossfire set-ups on PhII's. Would you get better performance on an i5 2500k? Yes. But, with your 965BE, would you get better performance from a 6870 than a 6850? Certainly. So no bottleneck.

 

[mosox]

It's fine. However if you have a monitor with lower resolution (1680x1050 and below) Intel is noticeable better in many games.

Hmm how's that? One would imagine that less resolution causes less strain on the system?

At lower resolution the graphics card would have less of a load, so if it previously was the most significant limiting factior, going to a lower res might shift the most significant limiting factor to the CPU.

This does not mean you get lower performance when you go to lower res. It just means your "theoretical peak performance w/ a faster CPU" will probably go higher when you switch to a lower res if you are no longer limited by the performance of your graphics card.

How did you choose what multiplier to use? Could you have gotten better performance if you kept the base MHz at 200 and used a x20 multiplier?

I'm wondering if there is an optimal way to figure out which multiplier will give you the best overclock with black edition Phenom II processors. Any suggestions?

I personally like my X6 1055T. It's been running at 3.8GHz at 1.375v since I bought it at launch and it has come in handy for video encoding especially. And I definitely liked the fact that it was a drop in for my AM2+ motherboard with DDR2, rather than me having to buy a new board and new ram.

I went from a Q9450 to an x6 1055t earlier this year. It's been a great move for me since I cruch SETI on it and never game with it, but going from vista x64 with 2gb of ram to win 7 with 4 gb has been a much bigger difference than the cpu change.

OT, but love your wallpaper.

I've got a Phenom II X6 1090T ~3.2GHz and it runs everything I've thrown at it so far very well indeed, and it was very cheap as well for a six core processor, about £105 I think. Only complaints I have is that it has quite a high power consumption (125W) when compared to similar Intel processors.

I ended up with those settings because of how the memory and cpu-nb would turn out on my ASUS M4A89GTD Pro/USB3. I could keep experimenting but I've already spent a great deal of time on this system

Try undervolting it. You'll be pleased with the results

 

[blackphoenix]

I can concur with that.

My 1090T will do 1.15v at stock 3.2ghz, much cooler and less power use.
If I put it at 1.3v I can do 3.6ghz, so still undervolting, but getting more performance out of it.

 

[lopri]

Been running 1090T for almost 2 years. 4.0 GHz core / 3.0 GHz NB and it's been a perfect CPU for me because I need those extra cores for my VMs. What I especially like was the stability of it. Only upgrade I made was to 16 GB of DDR3 this year and the CPU had no problem with it. It's doing my work-related duties and VMs while my 2500K is mainly for games.

How good is the stock 1100T cooler? Is it work going aftermarket for a 300 mhz OC?

It's likely the same one I had(have) for my 1055T. It seems sufficient, according to what I have heard, for a mild Overclock, but for me even at Stock speeds it gets crazy loud. You'll definitely want to spend an extra $30ish for an after market Heatsink/Fan, if you value your hearing.

 

[repoman0]

X4 955 at 3.6Ghz under-volted to 1.3V. Paired with an HD5770 it's more than enough for everything I use the computer for.. occasional games, audio compression and photoshop being the most demanding.

 

[jhu]

1090T stock speed. Will undervolt soon.

 

[Googer]

I suppose AMD LLANO APU Owners could also chime in on this thread?
