Phenom II Overclocking Guide - Page 15

post #141 of 253
Thanks for a great guide. I had never quite understood how to OC my CPU, nor did I have the courage. After reading your info something clicked and I thought I would give it a shot. It wasn't as bad as I thought. I haven't ventured into OC the RAM yet, so the hard part is probably ahead of me.

As far as stability testing goes, how does IntelBurnTest rank in the mix? A few of the sites that I visit swear by it. Others never mention it. I know it will peak my temps well and seems to give me a good idea on the settings I am using, but could it be used in the place of Prime95? The reason I ask is that I rarely have 6-12hrs to let my CPU Prime during the day and my CPU is in my bedroom, so Prime overnight if out of the question (married guys will understand my pain on this one ).

Also, on a side note. I have a 720 BE that I unlocked the 4th core and after a slight voltage bump and a few tweaks, have been able to OC it. Problem is that I can't monitor the temps. I have HWMonitor, CoreTemps, and I tried Rivatuner (but couldn't figure it out) with no results. On HWMonitor I am pretty sure that TMPIN2 is the CPU Socket sensor and it tends to run 5-8C* higher that any of the core temps when I had it running just 3 cores. It maxed out at 60C* on the last IBT i ran on max 20x. So I feel pretty confident that my temps are within an acceptable range, but I would like to be able to verify them. Is there a way to actually see them or am I just stuck guesstimating?

Thanks again for a great informative guide. The way you explain things help idiots like me understand things so much better.

Glad that I could help you get your feet wet with OCin, and really, its not all that bad once you get into it (as you're already noticing).

As far as stability testing goes, I have never actually used IntelBurnTest, and it wasn't until semi-recently(6 months or so ago) that I heard about it. From what I hear, it is an extremely intensive CPU stress tester, its origins are totally different than that of prime95 (which was not designed as a stress tester, but it just so happens to be great at that).

You can read about some various OCN'ers think about it HERE. The general consensus seems to be that while its great at stressing the CPU (more so than is possible than pretty much any other program... its kinda like the furmark of CPU tests if you're familiar with that program. The only complaint I hear about it is that it doesn't really stress the memory much.

From what it sounds like, it would be great to test the OC while you're progressing with the OC, but then you'd want to check for stability with something else in addition to about 10 passes of IBT.

I hear you about the having time for testing the OC... I don't think my wife would appreciate the site and sound of my rig running prime95 all night while we tried to sleep...

You're not alone with the temp reporting problems, and worse yet, there doesn't appear to be much that you can do about them in terms of software (like the old brisbane X2's). Your best bet is using an IR gun pointed at the base of the HS, or guesstemation like you've been doing.

*Another 'really' rough way to check temps is with the BIOS. The BIOS for some reason seems to be a 60-80% static load on the CPU. So you can check your BIOS temps (which are usually correct) and then figure out what the 100% load temps would be (you'll end up with a range of temps if you use 60% and 80%). At the very least this should help confirm if your other guesstimations have been close.

Anyway, sorry for the wall of text. And also, I just tried to write this so I could understand it, and then hoped that everyone else could make sense of it. Because if I can understand it...

Cheers!

I really want a ASUS M4N82 Deluxe to get the most from my Phenom II X4 940 AM2+
UPDATE - I am now stable at 3.62Ghz with the FSB set to 213Mhz and multiplier up to 17 core voltage at 1.40V. temps are a high 59 deg when fully loaded and 39/40 when idle. I have modified the air flow by tidying up the cable runs and allowing a better intake of the air (removed the Floppy Drive!) Sound levels are still low and acceptable. I managed to get my GTX275 to 700Mhz GPU and 1210Mhz memory so bioshock plays and looks amazing!

Cheers

I just built my first PC, and will be trying my hand at overclocking after finals are done next week. This will be helpful, thanks.

First off, just want to say thanks Logan for putting this thread together. It was very informative!

Using this guide so far I managed to get my unlocked X3 720 pushing 3.6ghz. I'm using the Scythe Mugen 2 cooler, and under load my temps stay in the early 40's, to mid 40's.

I seem to hit a wall and was wondering if anyone has suggestions on how I can squeeze a bit more out of it. I'm thinking my ram timings may be the problem, but I'm not sure. Right now my settings are:

The are my settings at the highest I can get them without losing stability (Tested under prime):

CPU core multipler @ 18X
CPU voltage @ 1.4250
NB VID @ 1.2000
Memory VDDQ @ 1.900
NB Core @ 1.100
HT Reference clock @ 200
Crucial ram (4G) with timings of 4-4-4-12 @ clock 3.33 (667 mhz)
BFG GS series 550 watt PSU (80 percent efficient )
Diamond Radeon 5850 (Stock settings)

When attempting to play around with different settings, the types of stability issues I encounter is a reboot, or if not a reboot the blue screen of death with a physical memory dump.

Any suggestions, or should I just be happy I got it running stable at 3.6? It seems like it's running cool enough I can run it higher without worry of stability or damage. But maybe I'm just being greedy.

Glad I could help out .

Ok, so right now your ram isn't the source of your instability. You're OCin with the CPU multiplier, so its not affecting any of the other settings other than CPU speed. Does that make sense?

In other words, if you were using the reference clock to overclock, you would need to mess around with your ram settings to keep them at the stock speed. But because you're not doing that, you shouldn't need to worry about it.

I would actually venture to guess that your voltage is to low. 1.425v is pretty low for 3.6GHz on an unlocked 720 BE. I would think that you could try increasing the vcore a bit more and see if that helps.

Good luck

OOPS.

Well that makes sense. I was messing around with my ram timings trying to get it to work and it didn't make any difference. Haha. I think I got confused because originally I overclocked it using the other method, which worked well. But this multiplier method seemed more simplistic so I went over to that.

I'll increase the voltage to the CPU and see if I can get a bit more out of her.

Thanks!

I'm currently at x 19.5 and about 210, this is giving me 4.1ghz on a AMD 555BE unlocked to a 4 core, I've got the cpu voltage at 1.56V. at this voltage it seems stable and did a full prime95 test, temp not higher than 48°C full load.

is this voltage a bit high ?
