Just my opinion but what would be the best software to bench it at say fir ten or 20 minutes

What you have to remember is wether AMD or not, if it passes prime at stock speeds then fails at an OC, there is something a miss. I don't think 10 or 20 minutes is enough to get a valuable result in any software. Maybe good for preliminary testing.

And if you don't want to burn up your PC, then stick well within settings that your pc can handle during long stressful events. Otherwise, you may one day install some heavy program, maybe your fans are a little dirty and bam, you burn something up.

The way I look at it is if I can prime (Small FFT) for hours and stay within thermal spec, then I can be pretty darn sure nothing else is going to cause my system to over heat.

Intel burn test is good to start with but Prime 95 is the best in my opinion. I do a minimum of a 12 hours of each program and I do multiple stress levels at that. So all together I end up with 36 to 48 hours of beating up my chip before I consider it stable.

well I believe I hit a wall at 4830gz because 1.45v is all my new bios seems to allow. I tried to use control center and click bios to get to 1.514v but it wont go..lol can anyone send me a link for p95 or ibt as im on my phone and have no pc internet access. Any advice would be awesome as im tryin to get past 5ghz . Ive heard the older msi software allows up to 1.99v but tge new 13.5bios I flashed may be what is not allowing me past 1.45v

Make sure you get the rite version for your OS. And also monitor temps closely. I don't think your going to be able to use higher than 1.4v and stay in thermal limit though. You can try. 1.38v is about as high as I can go on decent air, and that is really pushing it. But maybe your rig will be different by a margin.

I am not very experienced with IBT, maybe someone else can help you out with that.

Realistically you may get to 4.6 or maybe 4.7 (Stable) on air. And this is being generous I feel. Unless you are lucky enough to have a very efficient chip.

well ive been runnin at 4.6 for a while @1.344v. And no increase in temps from 4.4 52c at load and I have really big air and a rear cpu fan . 8 fans total in a push pull with a top and rear and fresh air ftom all directions lol . Ive currently installef an older version of msi cc amd clickbios2 and finally got it to 5020 at 1.52v and a vdroop of 1.512 and im bout to test it with what ive been using (sandra) and its been lwttin me know pretty well how it performs so if it passes all cpu tests in tgat then I will feel safe using prime. I believe I have a very flexible chip as it would post fine @5ghz and 1.45v but would lock up when testing so ill let u know if its on cue and ready to prime.. it really doesn't get that hot. Its idling at 44 now when before it was 39 . I wanna keep it below 58 under load so ill find out here in a min lol.

Stress testing (not benchmarking) at 4.6 with 1.344v I think would be great..

CPU Voltage: 1.384v (Load)

NB Clock: 2400
CPU/NB Voltage: 1.2v (I think, will check then edit if needed)
NB Voltage: Auto

HT Clock: 2600
HT Voltage: Auto

RAM Speed: Auto (1333)





Check out my temps above at 4.6 with 1.384v redface.gif

Did another prime run today (Small FFT) at 4.5 with 1.344v. It passed 12hr. 46min. Then I stopped the test. 60C max. (6C drop from 4.6/1.384v) Lower CPU/NB clock/voltage also.

CPU Clock: 4.5 GHz (200 x 22.5)
CPU Voltage: 1.344v (Load)

NB Clock: 2200 (Default)
CPU/NB Voltage: 1.675v (Auto)
NB Voltage: Auto

HT Clock: 2600
HT Voltage: (Auto)

RAM Speed: (1333) (Auto)





Like you are, I was really hoping to get higher clocks. But thermal limit is holding me back. And I think one of my modules would hold me back anyways (cores 5-6) seem to cause issues above 4.6.

I will be adding a third fan to my cooler, as well as improving my cases airflow. Hopefully then I can do longer testing at 4.6

u have a similar clock but with a different aproach by using the multi.. I have heard a few times from others in the knoe that by fsb ocing with a lower multi is more efficient per thread and a higher clock can be achieved using lower voltage..I use all the same exact monitoring tools. And I see u have the 8320e 95w which mine is 8350 125w. Im sure theres a slight difference . Im currently at 4.8 1.42v and odling at 41 . Not sure how hot it will get. All I use it fir is gaming and daily regular usage.. I have no llc but my volts stay pretty stable.. heres my specs

4.8 ghz 240x20:1.432v 2640 nb and ht 1600 single hyperx savage 8gb( using single chip for testing)1.3v cpunb 1.355nb 2.5pll 1.2httlink everything else is auto with all features disabled . It seems stable in games so far with about 5-7fps increase and 20fps in a few games.. the new games take alot of power to run full60+ fps with aa cranked all the way up and everything ultra but it kills most games if I turn vsync off it hits 120fps easily in many games anf my mobo isnt even pcie3.0 . Ill prime it tomorrow for about 20 30 min to see what happens. U should maybe try mixing ur multi with a higher fsb as it seems more efficient and higher single thread performamce. My current cpu bandwidth is 2gb per core and it was like 1.7 before at lowerghz so it seems like I can get a higher clock with less voltage and lower temps with this setting

Ya, I am going to try some FSB overclocking as well. I just want to see what I can get out of it from multi for now, I get to confused if I try to many things at once without first nailing one thing down lol. Sounds like you are on a good path, keep it up. And keep a close eye on your temps when you start to prime. I usually will do a run for 1 1/2 hours to get an idea of my max temps before I will leave the test unattended, until I know what a given voltage is going to do (temp wise).
