phenom II x550 be

[Shingi]

calling AMD gurus here.

I have a HP(please don't laugh) that has an x4 630 in it. I took out the x4 630 and swap in my x2 550 be into it and use amd overdrive to overclock. Everything is great. I got the phenom to 3.7ghz at 1.4v. The problem is now I believe cool'n quiet is turn on. I get throttling from 800-3.7ghz. If I don't oc it stays flat at 3.1ghz. Bios as you know is from hp and is crap has no options for turning on/off c'nquiet. This leads me to believe that the throttling is being cause by amd overdrive because on stock setting it does not throttle. It is not a heat issue because my linpack test at 3.7 ghz and it tops out @ 58c. And the x2 is does not have the additional four cores unlock again(hp). Besides if it was a heat issue it would only throttle at high temps not on idle.

I already know what you guys are going to say next. go to power options and set cpu minimal state to 100 percent. I did but it works for a while then goes back to throttling, WTH?

is it Overdrive software driving the throttling? Is there a string I can edit to help?

thanks for reading and helping

My 3.5 GHz 1055T even with cool n quiet disabled still throttles down to 1 GHz when idle. I remember reading somewhere that Phenom II chips (certain ones?) has its own "Cool n Quiet" built in and can't be disabled. I imagine your chip is like mine.

OTOH, my X4 640 doesn't have this "internal cool n quiet" and stays at 3.3 GHz full time with cool n quiet disabled in the BIOS.

if that is the case, how does that explain the 3.1ghz stock and does not throttle at all even when linpack tested? Shouldn't it throttle even at stock?

ive been thinking about asking the ask the opposite for a few days

mine is a athlon x2 5600+ not oced idles at around 1008mhz, Is there a way to set the idle lower like 600 700mhz?

Oh really I didn't know this. I would think you can disable cool n quiete in BIOS. If the fan

From what I know its pointless to OC if you have cool n quiete ON , cuz it will make fan not spin as fast and your OC will blow up.

Im guessing the HP has locked BIOS options and this is one of them if you cant turn it off. HP doesnt want people to OC ya know. and their motherboards are special made by known vendors like gigabyte but its just a limited BIOS.. My Cousins ACER Q8300 has literally 1 bios option,, nothing else,, soo he can't OC the CPU. This is what you get when you dont do a build by yourself. thx

I know what you guys are saying. I'm trying to confirm that this is an AMD Overdive issue causing the throttle, and if there is a way to disable it. If this was a bios issue then why doens't the cpu throttle at the stock speed. It only throttles when oc using AOD. If i uninstal AOD it returns to normal 3.1ghz constant and does not throttle. Anyone here using AOD please help.

somebody must know?

I'm amazed, you bought an HP OEM, and it is letting you OC through the BIOS? Didn't know such a thing was possible on OEM boards.

use amd overdrive to overclock.

Oh, that's how. Interesting.

in the top right hand corner of AMD overdrive there is a little circle.. green means CnQ and Red means full OC all the time. Click it to change it - hope this helps.

CnQ uses a 4x multi, so the default speed in 800MHz (200x4). If you lowered your HTT/FSB, you would see lower CnQ idle, but then your load speed would also be lowered. For example, a 3.2 GHz CPU would have a 16 multi. At 150 HTT/FSB, your CnQ idle would be 600MHz, but your load speed would only be 2400. In addition, everything based off the HTT/FSB speed would be lowered unless your also increased their ratios/multis, such as RAM and the CPU-NB (aka memory controller and L3 cache). The reverse is also true - a HTT/FSB overclock will raise your CnQ idle speeds.

From a power consumption standpoint, this would not have any real effect unless the lower speeds (both CnQ idle and load) allow you to reduce your voltages.

Most motherboards can be configured to automatically adjust fan RPM based on temperatures, so this isn't an issue. Many mobos come with software that do the same thing. In addition, modern CPUs have their own internal temperature-based throttling.

Your right yes...

Rhoxed,

Thanks for the info. I did see that. here is the problem. It now stays @ 3.7ghz but only so long as I don't restart, if I restart I still get the overclock but c'n'quiet is now running again until I open AMD and Recheck the button to red. I think it's a software glitch in windows or some kind of setting because in power options it sets back to 5% when windows restarts. I have my own custom power option which i set minimal to 100%, but again upon restart it stays at 5%? WTF is windows messing with me? LOL

I feel like my computer is haunted because it doesn't keep the settings and neither does Overdrive. Who here likes to oc everything they boot up into windows?

Please shed some light here as it may be software or registry or something that's causing the default back to 5% or c'n'q being turn on auto when windows restarts.

Thanks
