Phenom overclock question?

[dacca]

hey everyone, thanks for all the help you have given me so far, really appreciate it, but again i need more, i have the phenom 9750 2.4ghz, looking to overclock it, now, i need a good guide to overclocking as i am very new to it, i dont want to alter voltages unless absolutely necessary, i just want the most out of my cpu without loads of hastle, dont get me wrong, if i can get great performance out of it with a bit of trial and error im all up for it, someone told me they got their cpu from 2.4 to 3ghz with minimal effort? just altering multiplier and fsb?

my mobo is the gigabyte ga-ma790fx-dq6

4 gig crucial ballistix 1066

xfx 4890 1ghz

zalman CNPS9500A-LED cooler

little revision to this, how reliable is amd overdrive utility using the auto tune function? my cpu currently runs at around 40 degrees, what are the safe operating temps? keep hearing loads of different things regarding this

Your CPU manufacturer should have a data sheet or specification page on what the max safe operating temp is.

AMD Overdrive is as reliable as the hardware sensors which tend to freak out sometimes in my past experience.

If you want to overclock, you're going to have get over the idea of not adjusting voltages. I'd say that guy who said they got their clock frequency by adjusting multiplier and bus speed only was full of crap. I'd like to talk to him. And see a CPU-Z validation of before and after and an array of stress tests to prove its stable.

Every motherboard is different. Overclocking requires a lot more power. 600mhz overclock on one review I looked added more than two or three watts of power consumption that's for sure. 😛

Anyway, you need high quality parts and cooling to overclock successfully beyond a few hundred megahertz. So, Just adjust some voltages and see if you can get the o/s to boot. I'd say if it was me and I wanted to do a speed overclock. I'd start by raising CPU, CPU-NB and NB by .01 to .02v for every 100mhz. Then give it the smallest increments on one of those at a time until you boot successfully.

It's really all up to you. That's just how I did mine. There's no rules when overclocking buddy. Anyone who tells you you're wrong is the one who's wrong.

You can ease off the voltages one by one until you find out which one was the major factor in that frequency attempt. BE SMART! That's all I can give you until your next reply.

EDIT: This is assuming you don't change any bus speeds of course. You may do that if you want but, you may have to increase voltages on more than just those 4 major components.

hmm.... im gunna have a play around with this once im a bit more confident, i was hoping there was a very simple way to do this, may give the amd overdrive a go and see how that pans out. I only really want to overclock as im told that my cpu is limiting my 4890, is the heatsink i have an adequate after market cooler for a good overclock? i noticed it lowered cpu idle temp by around 8 degrees from stock cooler, thats on minimum fan settings aswell

 

[Gixbit]

well I'm at stock speeds and my idle is 29-31. What's yours? Higher than 40C? You won't get much if anything decent out of that. There's no simple way to do it. Software overclock takes more time. Don't bother.

 

[dacca]

im idling at around 40 degrees, which is higher than most people i know with same cooler, my case is very well ventilated with lots of fans, so unsure why it runs so high, but amd say that the temp is fine, i might try some different thermal paste at some point, as im using zalman own brand stuff, been told that there is some good stuff you can get to lower it, i think i will try an overclock tonight, im only looking to get as high as 2.8 if possible, that way at my native res should reduce what small amount of bottleneck im getting with my 4890 (fingers crossed) thanks for your replies dude, very helpful

 

[Gixbit]

Well, My suggestion from here on is to maybe get some MX-2. Apparently better than AS5. Re-seat your cooler. Try it again. You can try different air flow too in the case. There might be a heat pocket. Who knows.

Since I'm pretty sure we're talking about an After market HSF.

yeah its this one here, http://www.zalman.co.kr/Eng/product/Product_Read.asp?idx=277 i have to be honest, i was expecting to see more of a drop in temps, some people said around 15 degrees, airflow in my case is as good as i can get it i think mate, got a 120mm fan at the front sucking air in and being vented both toward the gcard and cpu, then the heatsink of cpu is sucking that cold air back toward 2 80mm fans at the rear, the powersupply above this sucking air from the cold zone above the 2x80mm fans, 120mm fan on the psu. At the bottom of the case the cold air that is sucked in from the 80mm fan, gets sucked straight into the gcard, and any area of warmth below this is taken out by a fox1 pci blower, the case is a full tower case with plenty of room around everything, really i should be getting much lower temps, my system temp sits around 40 with fans on low, when turned up it drops to around 30 but very noisy.

Well, if you're hoping for a quiet overclock, You might be disappointed to find that's not really realistic. We're talking about keeping an overclock as cool as possible. If you got RPMs you're not using use them. Turn off any PWM and fan control settings. Run it at max speed.

Also might want to try getting some MX-2 on there as well.

 

[renzuokun]

yeah hes right. honestly if you're going to overclock youll want the max fan speed you can get. Hell i plan on getting the coolermaster v8, now that things a freaking beast.

 

[Gixbit]

ahhhh, I might have to reseat mine at some point. I was getting up to 58c@3.8ghz on my 955BE. Or that might be about right? At stock frequency on full fan speed my idle is only 29c-32c. I used some MX-2 not AS5. I didn't use the stock paste that came with the V8. So, I wouldn't know what to tell you about that.

Don't worry about noise, worry about cooling that beast down. I'll never understand gamers who want a silent build. When I pump my music and I got my fans on max I can barely hear it and when I game? I don't even notice it. You Tune it out so to speak! Wear a headset too. What can I say? Maybe some people are fussy. Maybe some people don't mind it.

(Btw, Don't get too excited with the PCI slot fan adjust, it doesn't fit very well in some cases due to the thing they use to keep it in place on the bracket. I just sling it over the back of the motherboard panel and throw it in one of the loops I feed my cables through. Lol.)
