post #7371 of 19540
Alrighty folks, I am determined to get 4.8 ghz stable. Temps are insanely low here plus I just changed out many things in my water loop... Now have an xspc ex 480 in push pull with ap-15's and a phoyba g-changer 420 in push cooling the cpu and r9 290x. Since the de-lid, temps have been crazy low too. Here's where I am at:

48x core, 1.41 vcore
44x uncore, 1.3v
input voltage 2.0 v
xmp profile 1 (gskill trident x, 2x4gb 2400)

Have been running xtu for about an hour now. Think it will be fine, but I ran into issues before when I worked on this when I started bf4 so I will give it a go soon. Now that i'm back to windows 7 over 8, i'm hoping I can get some better clocks.

Max core temp is 65 C

I've been using the XTU benchmark for stability testing, seems to be pretty solid & very quick. I'm actually running the x264 test looping for 20 passes right now to see how that does, but so far getting XTU benchmark stable has been fine for IBT using lots of memory, & folding on the cpu at 100% load for a month straight.

Nah I found XTU to be wayyy too light on my OC attempt on my old chip. What sort of voltages and frequencies are you pushing around?

I dunno, I have managed 30 days folding at 100% load without a hiccup only using XTU bench for stability on the 3930k.

Playing with a 4670k right now, testing 4.7Ghz 1.185V (set in bios, 1.94V - 1.202V on the multimeter), 4.5Ghz uncore with 1.15V.
Got it XTU bench stable, then ran 10 passes IBT with lots of memory, now on pass 9 of x264. I used to use cinebench for initial testing then fine tune to get IBT stable, the XTU is quite a bit tougher than cinebench & not much if any fine tuning needed on the chips I've used it with so far.

That's very interesting smile.gif I personally pass XTU about 50mv below my x264 30 pass voltage

I remember you saying this before.. you sure you're doing the Bench and not the stability? The bench is where it's at.. do that multiple times to confirm it passes and you get same results, gives a fairly good indicator compared to anything else and fast (IMO).

I've found the Asus Real Bench to be a pretty good quick stress test. I can run Aida64 for 12 hours+ without a crash, but Real Bench would crash within a half-hour. If I can run 1 hour Real Bench successfully, I'm generally good to go.

Yeah I gave the bench a fair shake too, didn't have much success with it (in terms of stability testing, that is). Maybe I just had a weird chip lol

And I found LostPlanet2 - test2 very handy for quick stress testing.. It last only ~2-3min and it will show cpu and whole system instability really quickly. Also no need to overburn the whole thing.. xD

dx9 mode, 1366x768 or 720p, no aa so its cpu bound. Also jobthread=8 in game cfg. (mydocuments/capcom)



It can act like so and when set properly its stable in everything, even BF4. At least on my z87delux mobo

*Tested in LP2 benchmark, jobthread=8, 720p, no aa, no blur, dx9; Test2
I didnt touch anything, cpu was at 1.225v, LLC6, SVID 1.76v and asus multi core enahnce off.

Cpu phase - standard, Cpu current 120%, lower temps but can bsod at higher load.
Cpu phase - standard, Cpu current 130%, lower temps, but I lost 2fps on avg (~122fps)
Cpu phase - optimized, cpu current 120%, 1-3C higher temp on hottest core, fps ~124.5fps
cpu phase - optimized, cpu current 130%, 4-5C higher temps on hottest core, max avg 125-126fps.

Testing with a few different stress testers is usually the way to go anyway, I just like the quicker ones since I change hardware, overclocks & OSes often enough that it isn't worthwhile to spend hours testing. Other than folding the 20 pass x264 test is probably the longest stress test I've done in the last 4 years.
