So, I got CrystalCPUID yesterday to simulate Cool N Quiet on a mildly overclocked processor (+200mhz with a -0.025 undervolt, stable on orthos overnight). I read through the guide to it on here and looked around for other guides.
So far I have it changing the multiplier. It thinks that it is changing the voltage, but SpeedFan and CPU-Z tell me otherwise. They always showed me when Cool N Quiet changed the voltage.
I have Cool N Quiet set to auto in my BIOS and have tried it on both minimal power management and always on and it still doesn't change the voltage. What am I doing wrong? Does Cool N Quiet need to be turned off in the BIOS?
CrystalCPUID not dropping voltage

Re: CrystalCPUID not dropping voltage
There that is the problem. You need to do the undervolt with CrystalCPUID instead of the motherboard BIOS.Ch0z3n wrote:So, I got CrystalCPUID yesterday to simulate Cool N Quiet on a mildly overclocked processor (+200mhz with a -0.025 undervolt, ...

Haha, thanks. I saw your PM right after I posted this. Thanks for all your help by the way. Maybe you should make a comprehensive guide for CrystalCPUID for people like me who make tinker with the bios settings before getting everything on the front end working.
On a side note, it is fairly disheartening to me that the 5400+ BE seems to overclock equal to or, rather, more poorly than the 5000+ BE. Everywhere I have seen, people have no problem with the 5000+ getting stable at 3.2ghz, which is a 600mhz, with either a very small or no voltage increase. Most people seem to only be able to get a 5400+ to about 3.2ghz which is only a 400mhz overclock. Mine on the other hand, 3.1ghz isn't even stable with a 0.025v increase and going to 0.05v only gets me to 3.2ghz and I don't want to run that hot. It is a personal preference because I am using a Ninja Mini and the Brisbane temperature sensors don't give useful outputs. So I have it at 3.0ghz right now and I could use a 0.025v decrease and still be stable. But, that also only means a 200mhz overclock.
Before you ask, yes I reduced the HT multiplier and increased the voltage on the ram slightly and reduced it's speed and loosed the timings when I was testing for CPU stability.

All the recent Brisbanes I've had could manage ~3.2 GHz at some voltage. The X2 4400+ I kept was actually the one that needed the least voltage.Ch0z3n wrote:On a side note, it is fairly disheartening to me that the 5400+ BE seems to overclock equal to or, rather, more poorly than the 5000+ BE.

I don't really need CPU speed on this system, and having a fast HT speed gives the biggest real boost (w/ the 780G), so I have the HT 5x240 MHz with a 10x CPU mutliplier. I haven't gotten 5x300 MHz HT working yet.
I thought someone wrote a guide on here to using CrystalCPUID.

Yes, only important for IGPs.Ch0z3n wrote:Why is the HT so important? is it an IGP?
Yes, the same chip is sold for $20 and $1000 at times. The 45W Brisbanes are also the same as the 65W versions. How good (voltage required for stability) your chip is luck-of-the-draw, but the high clockspeed, low TDP chips should be the best. I just buy whatever is cheapest.That is exactly my point, it seems like all the 65w Brisbanes are the same chips just with different default multipliers.
