I have done many upgrades over the last 12 years and this is the first time where a CPU has been automatically underclocked on installation. So its taken me somewhat by surprise. The manual with the mobo is somewhat vague over CPU settings and leads you down the path of leaving everything to the default settings, in this case half speed and a lot worse than the CPU it replaced.	cshwone (11921)
775752	2009-05-22 10:54:00	cshwone Nice quad. I just did some googling. Looks like the chip itself utilises AMD Cool n Quiet - ie throttles down just like Intel's speed-stepping - to reduce power consumption when not required. "AMD Cool N Quiet" (revision 3.0), it reduces voltage (power) while sacrificing some processing power (Mhz/Ghz) temporarily whilst you are not stressing your CPU. So - best bet, grab CPUz + Prime95. Run Prime95 and have a look at CPUz while it's running. You'll see the frequency jump as the cores get fully utilised. To remove CnQ, open your BIOS setup menu and look for the option to disable it. Oh and Paul.Cov - I know advice well meant - but actually checking which processor etc first (googling) might be beneficial. 4 cores - each running @ 3.2 Ghz.	Brooko (8444)
775753	2009-05-22 10:59:00	cshwone Can you set it to AUTO - rather than specifying a multiplier? That way you get best of both worlds. I have a Q6600 - small OC to 3 Ghz - but once I got it stable, I turned speed-step (equiv CnQ) back on. Now processor idles @ 2Ghz - but immediately ramps up to 3Ghz when required. Funniest thing is watching individual cores do it (some @ 2, some @ 3).	Brooko (8444)
775754	2009-05-22 11:07:00	I switched off Cool'n'Quiet first. Made no difference, the system wouldn't throttle up. What seems to happen now with manual x16 is that the system now acts like speed step and will ramp up when required. (Previously it wasn't getting past 1.6 per core) Now its up to 3.2 per core. Not really fussed about OCing, just want the system to run at the advertised speed.	cshwone (11921)
775755	2009-05-22 11:18:00	I'm just downloading your mobo manual now (it's crawling at 20kb/s). I'll have a quick nosy through the bios settings and post back if there's anything else you can try. Is it permanently @ 3.2 now - or is it actually idling lower? EDIT OK - took a look at the manual. Looks like (in MIT section of BIOS) - you can just leave everything at AUTO - make sure the clock ratio is set at auto too (rather than the 16X you reset it to). Enable CnQ again - then reboot and see if it actually is stepping when under load. The CPU-z & Prime combo will show really quickly! However - if you just want to run at 3.2 permanent - leave the setting as you've got them (ie CnQ off and clock ratio @ 16x). The reason it wasn't stepping before was because of the manual setting @ 8X. HTH.	Brooko (8444)
775756	2009-05-22 11:26:00	It actually idles lower, around 800 MHz and then ramps up when required. Pretty puzzling really, its almost as if the various technologies are getting in the way of each other ie, normal user like me > low idle then max when required (up to the advertised limit so no real stress on the system). Overclocker > probably set high above normal speed at the limits of system stability. Any ideas you have would be most welcome. Thanks	cshwone (11921)
775757	2009-05-22 11:45:00	Just edited my above post - you can try that first. What's the multiplier range on the CPU (8-16 right)? If you're running @ 800 Mhz - then that would indicate lowest @ 8 x 100 FSB which definitely sounds screwy. First I've heard about dynamic stepping of FSB and multiplier :horrified My multiplier on the Q6600 ranges between 6x-9x. My FSB is at 333 - giving me 1999 - 2997 Mhz (2-3 Ghz). Your FSB should be @ 200. 8 x 200 = 1.6 Ghz. 16 x 200 = 3.2 Ghz. You might want to check that your FSB freq is set to 200. If it's not - then it's almost like the factory settings for the mobo were 'play-school' mode ;) Sorry - don't know enough about AMD boards to give you a really informed opinion. If no-one else here can assist - try googling the board + 'over clock' - eg "GA-MA790FXT-UD5P over clock" I know you don't want to clock it up - but it should give you a lot of info regarding bios settings & a greater understanding of how they work together. it's how I learnt a lot about my P5Q Pro + Q6600.

The 955 is unlocked so 4x/35x multiplier. It actually idles lower, around 800 MHz and then ramps up when required.

Overclocker > probably set high above normal speed at the limits of system stability. Yes 800Mhz is correct for CnQ (My 940 does the same). Leave it as is as it doesn't affect performance. Are you able to stress both cores with ORTHOS? If not then run two instances (set affinity in task manager 0/1 and 2/3). Pretty much you should have Multi = Auto, PCI-e 100Mhz, HTT/Bus speed = 200	trinsic (6945)
775759	2009-05-23 00:52:00	Thanks trinsic. So do you just set the max multiplier you want (eg default is 16), leave FSB @ 200 - and with CnQ turned on, it will go between 4-16 on demand? Just curious. The 35x multiplier seems a bit OTT. I was reading the reviews - and most early 'hobby' OCers seem to be only around the 3.6 - 4 Ghz (eg 200 x 18-20). Still I bet it would be fun to play around with if you have a decent board and a good AM cooler :thumbs:	Brooko (8444)

Still I bet it would be fun to play around with if you have a decent board and a good AM cooler :thumbs: Yeah pretty much, when not in use it will go to 4x, if you run something that needs a bit more it then goes to 8x I think and then full 16x when required. My 940 runs at 4x on all desktop applications and the only time it goes up is during gaming :) Intels SpeedStep/C1E is the same as CoolnQuiet. SpeedStep lowers the multiplier and from memory C1E lowers the voltages, CnQ does both together. It will work at any multiplier so if you set it as Auto or x16 then it should work as normal. If you're not overclocking then just setting everything to auto is best. The reason for a high multiplier is for use with memory timings most likely (and also to sell a CPU that can go higher than its default multiplier aka Black Edition). Also wouldn't you be pissed if you had an unlocked CPU and reached its multiplier? Hence the insane 35x ;)	trinsic (6945)
