Im looking to overclock my CPU, but keep hearing Rumblings that this paticular version will not over clock that well, is this true?

If so what can i do? How Can I overclock?

I have read the guides, but still seam to have some truoble getting to grips with the numbers ect?

I have above CPU, Black Edition.
MSI K9A2 Platinum AMD 790FX
OCZ DDR2 memory.
ATI/HIS Radion 3870


So what should I do first?

u could use the AMD overdrive or overclock via bios... just up the multplier and voltage if needed..

yes the 9x00 don't clock well. you'll be lucky to get to 2.6-2.7ghz...

OK, use the overdrive, not sure would that have been on the m/B disk or do i download it.

lol. 2.6-2.7 is better than 2.3 right?

OK, Well, i did play about in the BIOS with the Multiplyer settings, but it didnt really work very well.

download it here http://game.amd.com/us-en/drivers_overdrive.aspx

as i said you'll be lucky to get to that..

u also need to up the voltage alittle...
 
OK, cool, I assume there are instructions somewhere on how to use this? do you know what the Vcore should be? as I think it reads auto, so how am I supposed to know what to change it to if I dont know the Orginal?
Thanks for your help!

if u use overdrive it'll say.. also u can up it using overdrive.. or look in bios under H/W monitor

Using bios on my asus crosshair, am getting a reliable 2.75 with a 9850, old 9600 would only got to 2.5 on stock volts, any more on any voltage and i get random blue screens.

Overclocking using the multiplier on Phenom chips is the only practical way to play with them.

Forget everything you know if you've used an Intel chip as - whilst identical in aim - the procedure is vastly more complicated.

The Black Edition - being multiplier-unlocked - can be overclocked just by setting the multiplier higher. Basically do this until the chip becomes unstable (Orthos for at least 8hrs, 3Dmark06 for 4hrs. encode a full-length movie into DIVX/MKV and then SuperPi/PiFast to 32m decimal places... all followed by 24hrs of Toast - this is what I would consider a full stability test). If the chip passes each overclock with such settings, you can be reasonably sure it doesn't need additional voltage to go higher.

The thing with Phenom is better performance is available by tweaking the Northbridge clockspeed (no, not NyperTransport). Increasing the northbridge frequency has a direct impact on L3 cache latency which is a serious stumbling block for the chip.

If you decide you want to play with the Northbridge frequency, make sure you increase it so that its final total value (i.e. once appropriate multipliers have been added accordingly) is higher than the Hypertransport value. You will not get any stability at any voltage if you do not follow this principle. This is why so many benchmark sites had problems with Phenom overclocking before the Black Edition came about.

Another thing to remember is that Northbridge voltage can be adjusted independently to the CPU and RAM voltages. By the same token, dont give it too much juice (put a limit on 1.45V for pretty much all CPU-bound things if on standard cooling) or it will kill the chip.

Just take your time, head over to http://www.xtremesystems.org/forums/forumdisplay.php?f=58 (but READ the threads; don't just go and ask how to overclock your system) and enjoy.

Blimey.....thats one hell of a stress routine, overkill in my opinion as when would you ever recreate anything like that in computer use. Orthos alone is more of a CPU stressors than 99% of computer programs, testing that extensively must notch up your power bill quite nastily.

Damn right. But if Orthos alone were an effective stress test, why do some people who post on this forum claiming to have done up to 24hrs of successful Orthos testing then get failures as soon as they stick a game on?

The problem has been reduced by improved platform stability (8-phase power circuits, solid-state capacitors, better cooling), but the only way to make sure one's PC is completely stable is by running through a rather offensive mill. The tests above are what I would consider best practice, but not necessarily practical for every 1MHz increase in HTT/FSB frequency. Run them successfully on your final overclock and you really shouldn't havea problem.

Toast is an awesome heat-load tester. It makes Orthos look like the equivalent of sitting on a beach.

The problem with Orthos is people tend do to be doing nothing else with the PC while its running.
i have many times had Orthos going for hours & as soon as i start something like even winamp it fails.

Didn't expect that.

That is because Phenom has been denounced on these forums as a useless chip, which the B2 chips pretty much were. The B3s are much better, as you can see.

Shows what happens when only one side of the story is widely publicised.

However, overclocking Phenoms is a very delicate process - much more complicated than with Core architecture. By the same token, it is also described as more rewarding... go figure.
