Dont touch the ram timings, if possible set the board to optimized defaults, save it go back in and under ai tweaker set docp (xmp) then set your ram to the profile specified and then set your multi and voltage as onemoar said

 

[Viem]

raise the multi to 19.5 and set the voltage to 1.40 and see if it boots
if it doesn't boot at that try lowering the multi to 18
also try overclocking the nb to 2600Mhz
you really need better cooling to push a x6 they do get quite toasty

Yes I agree. On the upper egde of the case sometimes it gets hot enough to keep beverages warm during winter...

I'm thinking to get another CPU (8350 )rather than to buy a better cooler or a watercooler for the one I already have, though. I'll try what you suggested when I'll get home to see what may happen. Thanks a lot!

 

[eidairaman1]

Stick with what you got and then see how far you can go with it. Read my prev post.

I believe your ram timings are 9,9,9,24 at 1.5V

8350 is the way to go, it really shines in video rendering especially if the software is multi-threaded and I do like it in games, seems much better experience playing games.

The 1090T still has quite a bit of life left in it though. If you can geat up to the 4.0 mark with some better cooling. I wouldn't be too quick to jump into an FX right away. Although you dohave a good foundation already if you felt like doing so.

It booted normally , once I applied the settings exactly as you suggested. It's running now at 3.9 Ghz. When I entered Windows I ran a stability test for 5 minutes in AMD's Overdrive and everything appear to work well until now. Temperature is at 38,5 - 39 °C at idle and while the stability test was running it maxed at 60 °C which I guess is normal.

Yes my RAM and their voltage are these, exactly.

Here's a screenshot of what is done.

 

[OneMoar]

if you encounter any stability issues give the cpu-nb NOT the "Nb" voltage a slight bump usually 2600 requires a bit more voltage try like +0.050V
if its stable at 19.5 you should be-able to go all the way to 20 and get a even 4Ghz *with better cooling
I would do some gaming tests first

 

[eidairaman1]

Get prime 95, occt, ibt.

 

[OneMoar]

I would run at least 8 iterations of prime
also prime will overheat it with your current cooling now know that we know it posts at 3.9@1.4 and doesn't immediately bsod its time for some better cooling

 

[ThE_MaD_ShOt]

I have my 1090t set at 3.6 with just multipler adjustments. Runs stable as a rock.

 

[Viem]

I 'll next try prime and post the results! Thanks a lot guys!

Well, after multiple attempts with Prime95 my system keeps getting BSODs in the first 10-15 seconds of me starting the torture tests. Opposite to that I played some Battlefield 3 and everything was working good without errors during a period of time of about 40 minutes gameplay. I put all the fan profiles in Turbo mode in BIOS prior to that and surpisingly the temps went down to 33 °C while gaming. Should I keep it as it is or should I set it up differently until it 'll become stable with prime95 passing the torture tests?

I want to get more computing power out of my Phenom II x6. What should I watch for?

Mine's being cooled by a CM Hyper 212 Evo and runs great on a Asus Crosshair V Formula despite it being an AM3 CPU on an AM3+ motherboard. Also I know that my case, CM's Silencio sucks for keeping components cool but I want to render videos a bit faster and get the best possible frames in games like Battlefield. I 've read it's possible to OC this CPU without burnning it out, but i'm a complete newbie in overclocking and my bios looks to me like it's written for extremely advanced overclockers when I look at all these options, which are avaliable for tweaking there.

So, what should I do first to OC my Phenom II? In what clock frequecy should I try to set it first? Do I have to go up with the voltages for this, if yes how high ? Also, what would be an acceptable temperature for the CPU after the OC is done, based on an air-cooling option?

Anything else worth mentioning? please post

Thanks in advance.

Looks like I took too long to write my guide.

Spoiler

CPU speed is determined by FSB (often given other names these days like "Bus Speed") multiplied by the CPU multiplier (or for Asus, "CPU ratio"). The stock values for you should be 200MHz FSB with a 16x CPU multi. Since you have a Black Edition processor, your CPU multiplier is unlocked. If it wasn't, you'd have to overclock by raising your FSB which also (typically) overclocks much of the rest of your system and can cause instability due to stressing out other components. The easiest way to bump up clock speed is to raise your CPU Multi. Unless your motherboard monitors CPU frequency and adds voltage itself, you shouldn't see too much of an increase in temperatures. When overclocking, make sure you're not sticking excessive voltage through your chip (I think 1.5v and above is excessive on these things. Can't quite remember.) and make sure your temperatures are okay. You'll also want to watch your VRM temperatures.

For now, I'd suggest leaving voltages at stock and just see what you can get out of it for free. Bump your multiplier up either 1x or 0.5x, save and reboot, check stability and temps, rinse and repeat. When you start to get errors or BSODs, go back in to your BIOS, move the multi down to wherever your last recorded stable point was. If you can't remember, try just lowering it 1x on the multi.

You should see something in the BIOS like this:

If you can keep in it the 40 to 50c range under load you will be golden.

P95 is a lot harder on a CPU than AMDs stability test. If you want to pass P95 you'll likely need to dro you OC a step or two. You were already reaching high temps and P95 will make it a lot hotter.

 

[OneMoar]

take the multi down to 18 and run prime again I knew it wasn't gonna pass prime small fft just wanted to get a ball park of what the chip could be capable of on better cooling


if it passes at 18 then order a better cooler and you should be-able to get 20 @ 1.48v or so
I would go with a good air cooler or maby a double 120MM AIO
avoid the single 120MM aio's they aren't worth the cost
@
he doesn't need to raise the mutli one step at a time it booted at 3.9 and is stable enough for battlefield 3 witch means hes REALLY close to getting it rock soild he just needs better cooling and maby a touch more voltage he can go all the way up to 1.52V on the core and 1.3V on the CPU-NB if he really needs it but he needs better cooling and I don;'t think he will need any-ware near that much voltage
based on what I have seen once he gets the cooling sorted he should be-able to get 4.0 @ 1.48V

 

[Viem]

Seems like the only way to stay comfortably close to 4 GHz is to get a better cooler. So once I'll get a better cooler my system will be fine with these settings. I'm going to get a Corsair Hydro H100i for my Phenom and to try again the steps OneMoar and others advised me. Thanks to everyone for your efforts, I apreciate your help.

edit: No 2x120mm sized radiator fits in Silencio 550 . What a bummer!

he could always get the tin-snips and do a bit of getto modding to fitt a double 120mm rad

I agree. I'm aswell thinking about making a mini customization on my case like drill some nice straight holes on the top of the case, to get the 2x120 and the nessesairy airflow and maybe add some kind of air filter in between to reduce the dust.

One easy solution would be to remove the HDDs cage and the other 3.5 slots (one is already removable, the others are not), to remove the air filter from the front side and install the radiator there in a standing position, but the problem is that in this way there wouldn't be enough cool air for the fans to blow on the radiator because of frontal design of the case. Other than that, I'm not sure if the tubes are long enough for what I want to do with them. But even if I manage to install the whole cooler inside the case, I still think that the warm air would keep recycling itself after two more fans would blow already heated air on the radiator. Currently I have 2 CM's factory fans in my case plus 1 more CM "excalibur" on the exhaust and that's what really happens inside my case.

So I think drilling the case on the top , fixing the radiator inside and leaving its fans externally taking the fresh air in would make the best result.

just remember to remove everything from the case before you start cutting
metal shavings are no Buenos for pcb's

Yes! Of course!
