cool and quiet and OCing

[confusingcomputers]

Hey guys, i had my AMD 3000+ Oced to 2.1 Ghz (235 x 9) and installed cool and quiet. Everything was working fine for about a day, then i checked my temps and i was running at 45C at idle. I was thinking, wow, that is really hot (it was running at 31C when cool and quiet was actually WORKING).

Well, i checked cpuz and my voltage had actually increased to 1.688!!! I only had it to 1.525 in the bios before i enabled cool and quiet.

Needless to say, i went straight to bios and disabled cool and quiet.I noticed that i didn't have the option to mess with my core voltage what time cool and quiet was still ienbaled in the bios. AFter i disabled it, my voltage was still set to 1.525.

I was just wondering if anyone else has encounted this?? I really like the cool and quiet feature...but i can't have it running if its going to do crazy crap like this. Does anyone know why it decided to increase my core voltage?

Might be an issue with the Bios. Do you have the latest version of it?

confusingcomputers - Sorry, I don't mean to be a jerk, but unfortunately some people will be. Do a quick search on the Anandtech Forums if you can before posting something...you can usually get your question answered w/o posting...saving you headache, time, and stupid and/or smart ass replies.

Now, to answer you. D/L RM Clock. It allows you to set min. and max. multipliers and voltage. If you're not using that, C&Q should be disabled if you're OCing unless you are using the stock multiplier.

I agree. RM Clock is a great program. It should come bundled with all Cool-n-Quiet capable motherboards.

hey, Lt4camss, i did do a search, and nothing specifically adressed my same issue. I actually searched google and didn't find much about cool and quiet automatically "increasing" the voltage above what it should be. I know some people use RM Clock, but i didn't want to have another program running on my computer using up resources. It seemed that most people that used RMclock weren't useing stock multipliers And yes, i know i should be using the stock multiplier, thats why my problem struck me as kinda weird. I guess with cool and quiet enabled my motherboard switches all the voltages back to auto and with my overclock (2.1 ghz) increases the voltages way above what they need to be. The reason i say it switches them back to auto is b/c with cool and quiet enabled...i can't manually change the voltage in my bios, it just disappears.

If you noticed i asked "I was just wondering if anyone else has encounted this??" I just wanted to know if cool and quiet did this to anyone else. specifically on the asus a8v. Thanks for the replies.

Sounds like yours is a motherboard problem. Did you try updating to the latest BIOS? Otherwise, RMClock is using a tiny memory footprint of 1,136k on my computer, and absolutely 0 percent of any cpu cycles. I'm fairly certain it will solve all of your current problems.

 

[confusingcomputers]

Yeah, i have the current bios. I may try RMclock eventually.

confusingcomputers - Oh man...well, I honestly don't mind at all when people post a new thread for something discussed in the past...just some people can be real piss ants about it. I think it's better b/c a problem may or may not overlap completely or be exactly the same as what's already been posted. I'm only saying it so you can save yourself the headache, lol. Anyway...there was actually a post here two days ago that was talking about voltage increases. It actually is normal to see that happen if you're not using stock multi. And from what I've seen people post, it seems widespread unless you use rmclock. Sorry your left w/ only that option man . Here's a quote from one post about this:

Cool n' Quiet is an AMD feature that allows you to save electricity when the computer is idle. When the CPU is idle and Cool n' Quiet is enabled the motherboard halves the CPU clock multiplier and throttles down the voltage. With less voltage to the CPU it runs cooler. Since the CPU runs cooler the CPU fan gets throttled down to, thus, making the system quieter. When you begin using the computer again the CPU multiplier automatically and voltage ramps back up to stock speed.

It is possible to overclock while running Cool n' Quiet and people do it all the time. The caveat is that you need to make sure you leave your multiplier at stock and overclock by increasing the HTT (FSB). Cn'Q works by lowering the multiplier to around 5x and lowering the CPU Voltage. This makes the processor run slower and cooler. Then the motherboard will sense that it's cooler and lower the CPU fan speed, thus making your system quieter.

If you overclock by lowering the CPU multiplier and then raising the HTT you'll get instability. When Cn'Q needs to restore your multiplier when the CPU is under load, it will use the stock multiplier no matter what you have it set to in BIOS. That could result in an overclock that's higher than your board supports at your settings and you'll get lock ups. So as long as you overclock with your processor's stock (maximum) multiplier you'll be fine with Cn'Q.

Actually LT4CAMSS, you are wrong. Voltage increases were not mentioned at all on the other thread, they only mentioned the multiplier increasing.

Anyway, I'm quite surprised that your voltage actually increased. The only way I can think of to have this happen (excluding possible bios/driver bugs) is if you, for example, set your bios VID to something like 1.3v and set the CPU voltage modifier to something like vid+20%. When C'n'Q raises the clock speed it also sets the VID to the default (1.4 for a winnie) and 1.4 + 20% will end up being around 1.68. I doubt this is what's wrong but I'm just taking a guess here.

I'm not sure about your motherboard but some mobos have dynamic overclocking settings. If you do have something of the sort you should try disabling it. If not then there's always RMclock. ^^

LT4,
Yeah, i actually read that thread, and like Furen said, it didn't really talk about your voltages increasing for some strange reason when you ARE using STOCK multipliers. Which is exactly what happened in my case.

Furen,
Thanks for the help and understanding exactly what i was saying. I don't remember seeing anything about VID with % values in my bios. I'll look into it tomorrow though, i'm sleepy and going to bed now. AS of now, i'm just running without cool &quiet b/c i dont really NEED it. I just think it would be nice to have b/c of the saved power and a little lower temps. I still run pretty cool at 34C at rest and 45C under load w/o C &Q

Another vote here. Its an excellent program!
