RIVE, 3960X & my 1st overclock, to 4.3: Suggestions? And guidance for 4.5?

Level 9
Hi guys, this is my first post to get some feedback on an overclocking attempt. I initially tried to go up to 4.5, but things just didn't seem to be stable (enough) even though at first all seemed well. I have achieved what seems to be a solid 4.3 using the settings below. I'm not a gamer, so gaming scenarios and loads will not apply. I won't be pushing this computer too hard most of the time, but do expect to have a lot running at the same time. I'd like to be able to bump up to a higher OC for specific tasks, like audio ripping/encoding (not professional) and batch image file conversions etc.

1) I would very much appreciate any comments or suggestions regarding this existing overclock and,
2) Any advice for best adjustments to push this to, say, 4.5?

My current 4.3 OC has VCORE between 1.344-1.352 volts at load (and 0.856 V at idle.)
With air conditioning running for stress tests, maximum temperature of my hottest core, with 15 hours of Prime95, was 82 degrees centigrade. Running AIDA64 (which is where I read my temps and voltages,) that stress test generally kept temperatures in the mid to high 60s, maximum hit 73 degrees. (I do realize these stress tests are not normal, everyday computing scenarios, and I am keeping perspective when evaluating the term "stable.") I also used Intel Burn Test.

Also, before CPU overclocking, but with XMP memory setting selected, I ran 3 cycles (12 hours) of Memtest86, with with no errors reported. I'm now entering my XMP values manually, however.

Unfortunately my 6th CPU core runs about 10 degrees hotter than my lowest, and usually 6-7 degress hotter than the next warmest core. At "idle" on this 4.3 overclock, the hottest core temp is around 34 degrees.

Here are my settings, and thanks in advance for your suggestions! 🙂

Hmm I understand how that could take the shine off a bit...two card readers! But only temporarily; I'm sure it's a great computer...but workmanship isn't what it was unfortunately. I'd be tempted to write a letter to the owner of the company...maybe he'd be shocked!

But even if it is a bit idiosyncratic, I'm sure it's going to serve you well. Maybe one rainy Sunday you can take off the cooler and replace the TIM and fit it back on, just to check it's mounted 100% .. but the temps aren't bad so like you say, just a trade off...and quiet is good.

And yes...fundamental....enjoy it....:D

Yep.......thats why I build my own...honestly...a 3960X processor mounted on a RIVE.....I wouldnt settle for an OC any less then 4.8 Ghz....thats an $1,100 chip......
The only reason I dove into a 980X yrs ago was for the OC potential with unlocked multipliers.....had I bought a 980X only to "settle" on an OC that folks were geting with a 920....ugh!!!!
Thee's something to be said about building your own Rig !!!!

Hi guys, hi rjbarker,

I agree with you, we are just talking about a CPU cost twice my 3930K that has overcome the problems of 4300.
But you will see that maybe it will be a problem of memories that I repeat do not deserve to be on a PC like that.
Instead, I see that you are also a veteran of my own experience with X58 when .... with my poor i7 920 push @ 4075 Mhz, then sold for a i7 960 only pushed to 4150 Mhz while I was expecting more, .... . just money thrown to the wind.
But then God has thought of him that, who have struck him with a ....pitiful lightning during a storm!
I then self-assembled this current PC and ... from what I see, I was right that I have not got one fantastic assembly as the one in question ... on which I would bet without a doubt!

Hmm, now I feel the need to tell my experience W/card readers:

When I spec'd my first sys W/a card reader, I wanted one that just worked good and would be reliable. So when I seen they were
One thing about those readers: They're all just cheap chinese electronics, buyer beware. Read the customer comments before buying a particular model. When you buy a prebuilt PC, they may not take such care in choosing cheap components; and may even just go with the lowest price for their quantity, and then only change the brand if/when they have multiple reports of failures. This is why a lot of us put together our own computers - despite sometimes enduring a lot of grief when our components fail or are not properly supported. /end rant

Overclocking is useless to me if it is not rock stable.
