Its a Nice feature to have for hot climates…
When I enable it the CPU temps are really low and its quiet too. no issues here.
The problem is, when this feature is enabled, framerates go down in games. I have noted this in almost all the games. and there is stuttering.
Does the feature reduce the overall performance of the CPU jsut to get the CPU temps down? The cool n quiet software (one with a green cpu-meter) shows the CPU running at 1100MHz. no matter how many windows I load or tasks I run it does not go beyond this. theoretically it should have fluctuated depending on the load. but it doesn’t. why?
I have enabled the CnQ feature in BIOS and installed the software in XP.
Rig:
AMD 64 3200 NC
ASUS K8NE-dlx
512 Mb TA
etc etc
CnQ feature varies the multiplier accordingly to manipulate the clock speeds as per load and thus lower the heat dissipation. But u probably knew that..
perhaps its not switching speeds fast enough in games? may be u cud try gaming with CnQ disabled.
Disable it when playing games. Sometimes it doesnt switch to full speed when a game is started. I’ve noticed it when running ut2k4. Just change from minimal power management to anything else in power settings and it’ll switch to full speed.
CnQ just reduces the multiplier to 4 or 5 based upon CPU from the default multiplier (9-13) when there is no load on the CPU. Thats all it does. Thats why the A64 chips are unlocked down. else CnQ won’t work
Hmm, actually I dont mind CPU temps in the range of 50-55 during gaming. thats why I have disabled the feature in BIOS. But the definition says that whenever the cPU load is less the temps/noise will be reduced, BUT it will be normal when there is load, which is not happening.
@Chaos, thanks. will try the power managment thing.
EDIT: do I need to keep the AI OC in the BIOS to standard or something. right now it is manual. and running at a small OC @ 2.3 GHz
using CnQ on my system for 4 months and till now no performance loss or problems encountered. I am actually happy with it as it reduces lot of fan noise when my dad is working in word.
Well if you are overclocking then you must disable the C&Q. Enable it only if you are runnuing the processor at stock speeds.
Yes sometimes it dosent work properly. Maybe a software update is needed.
I havent tried it personally as i havent ran my CPU at stock speeds at all. But I do know that the first thing you do while overclocking is to disable cool n quiet.
If its working for you then good. But its recommanded that it should be off when overclocking. Specially in the case where you touch your CPU multiplier for overclocking.
i kinda doubt this…cuz as far as i know for OCing u need to disable C.Q to get more options in the bios for OCing…or maybe it differs from mb to mb. I got a asus K8N and i have to disable it inorder to OC.
I am on ASUS K8V-X m/b and if i disable CnQ i can change the multiplier and the vcore. But since i am using the stock vcore and OCing by FSB i didnt turn off CnQ but if I can go for higher fsb then I should turn off CnQ
K8V-X won’t do more than 220 FSB anyway without causing BSODs. Even lower with SCSI drives. Its a crap chipset for oc’ing as it doesn’t have PCI/AGP locks.
well, I didn’t change the multiplier. changed the fsb to 210. also at the moment the CnQ feature is disabled, as I’m heavily into gaming for the past few days.
no matter how many windows I load or tasks I run it does not go beyond this. theoretically it should have fluctuated depending on the load. but it doesn’t. why?
