Noob here; need to OC Phenom II x4 965 to 3.8GHz - 4GHz - Page 5

Also, I guess I was a bit unrealistic thinking I could have both a good overclock as well as low power consumption/heat output -- so I think I'll leave it OC'ed as long as ambient temps are low (since it's winter). But because I live in Arizona, once we hit summer and outdoor temps reach 105-113F (ambient room temps ~78F/25.5C), I may end up going back to the stock settings to keep the load temps down.

Thanks for the help thus far! I really appreciate it.
Go back to stock setting? NEIN! Watercool that beast and crank the multi up to x20

How are the idle/load temps that I mentioned?

Also, it's not really worth paying $80 (Corsair H50) or $100 (Corsair H70) for just 0.2Ghz more than 3.8 -- although I realize there are other benefits. My brother bought an H70 just a few weeks ago, and after seeing it it made me consider buying one, but not for just .2 more than what I can do on air. If I want to push it to 4GHz, I would have to, though.

Turn on your power saving options and you'll see even better idle temps aka put it on balanced.

But I tested my system at stock and we're close. I was 31 - 48 degrees idle/load.

I would rather just save the money and buy a newer/faster chip later than watercool and push the system.

An upgrade is the best OC you can ever do IMO. You get more stickers to slap on your case!

I'm runninig ,and have been , for the last few months -- 3.8 @ 1.40V //
That's actually a step higher than required but I feel, given that I've turned LLC off, randomness from my PSU could have the Vcore wanting more.

RAISE THAT NB volt man ~! And I find it immensely difficult going from 3.8 to 3.9
The PC will boot at 4.5GHz if I want it to, but will DEFINITELY crash-a simple reboot- on p95 anywhere b/w 10 minutes and upwards.

BTW, AFAIK, U need 2.6-ish GHz on the NB clock to hit >3.8GHz on the CPU

TURN OFF LLC --- IT'll send BAD SPIKES across your CPU Vcore and remember that VDROOP is required- its an occurrence that by design, aides the thermals and the cpu itself-- there's an article on anandtech that explains in detail why you'd want to turn it off. GoOgle is ur friend!

If you're worried about vdroop, simply set your vcore to one step higher than stable . THATS ALL you should do. LLC = FAIL

Also, while I can run 3.8Ghz stable, the power consumption does not throttle based on use, it stays at 111.30W instead of throttling down to 14.8W or so. Is there any way to keep it down even with an OC? I'm considering doing this: http://www.overclock.net/amd-cpus/55...l-n-quiet.html. Thoughts?

I've added Rep to all those who have helped me thus far -- thanks!
That HWMON power consumption is BROKEN-- USE THE ASUS EPU for a more accurate power consumption idea by the CPU. FYI- that'll only work when NOTHING is altered in the BIOS- Just gives u an idea..

125W cpu - This means MAX TDP --- under something stupid like p95 or OCCT - in realtime priority. Don't go by these figures. You'll necer cross 4/5ths of this figure in real world full load applications like multithreaded encoding et al.

Whats your Nb-freqs?

Sorry I can hit 3.8 ghz easy if I don't touch the NB freq's at stock voltage.

Also can you show me the info about the NB voltage? I really want to see concrete info on NB voltage. I'm still under the impression its only good for FSB tweaks or for multi GPU setups.

Thanks

Not to necro an onld thread, but I feel like I can offer some observations:

(1) You CAN have a great overclock and still have power saving. CnQ is a perfectly viable option. And it works well with...

(2) LLC (load line calibration). I used to be a big hater and was afraid of so called "voltage spikes". Now, I've realized how much of a tool it is. With LLC on, you set the voltage in the bios and vdroop is GONE. e.g. I set my vcore in BIOS to 1.44v, HWMonitor reads voltage from 1.43v to 1.45v depending on the load. Hardly a "spike".

Think about it. Your CPU needs more power under load. While let the voltage drop under a load. THAT means that at IDLE your CPU is using more volts than it needs (to compensate for your load vdroop.

Just my 2cents.
