Do I have a decent 3920k 24/7 overclock?

post #1 of 19
Thread Starter 
I plan on running this 24/7. I know the upper end of the voltage is a little high at 1.488v /w 100% load under p95 but I am using powersaving so it would only ever hit that except under benching conditions at 100% output. It idles between 0.944 and 1.232v depending on whats running in the background. Under normal load gaming etc it runs about 1.445v.

I also have the intel performance plan so I am not worried about longevity. I rarely ever keep a CPU in my main rig beyond 3 years and even if it wears out before then I can get it replaced for free.

I mostly do light gaming, programming etc. I rarely ever do an encoding etc. I fold on occasion but I am building a dedicated machine for that so I won't be folding on this machine 24/7. Just occasional runs, mostly GPU.



I am using Patriot Viper III 2133 11-11-11-30-3T trfc 300 Memory.

I have been able to raise the clock to 2175mhz and tighten the timings to 10-11-10-27-2t tfrc 265.

I am quite pleased so far. Everything feels really peppy. I do believe I may be able to eek some lower voltages and a bit more performance out of her. Everything is stable so far, running p95 with custom blend using 90%+ mem. Temps max around high 60's, around 70C with p95. With general use they are way lower. Idle is low to mid 30's depending on room temp. =p

So what do you guys think?

Here's a nice little bench of my raid 0 ssd array for my main drive.



It's 4x OCZ Vertex 3's in Raid 0 on a LSI MegaRaid 9240-8i. It does not have a memory cache, it's only write-through. Some day maybe I will upgrade. Would really improve my small file performance. It tops around 1.8 gigabytes / sec in read performance though. A definite improvement over my Vertex 2 Array. =p

What did you actually OC it to?

Volts are much higher than I would like to see for a 24/7 rig

edit:

err...alright, 4891.1MHz

Yeah, too many volts for that.

That's alot of voltage.

can you finish 60 mins of small FFT OCCT? 6-8 hr of Prime blend? If so I'd call it stable, but 1.488 is alot for a 24/7 IMO.

Click the pic and then click view original in the lower right hand side to view it in 1080p. =p

Yes, it's stable. I will probably eek it down a bit while trying to eek up some settings. It only hits 1.488 during p95 100% load on all cores because of high llc. Under normal high load and gaming it's about 1.445.

I was able to drop vcore another 0.020mV. Also I went up on the frontside 0.1mhz and tightened some more timings. I am still doing some stability testing.

Vcore is at 1.420v now with max around 1.440v at 100% load. I think it's pretty decent for a 4.9ghz clock. Gonna try to get it down another 0.020mV. =p

Still more volts than I would like to see on a 24/7 rig, you're chip though.
