[CLOSED] Haswell-E Vcore @ 4.5ghz Hey everyone, Made a new rig last week based on a i7-5820k. I went for the "safe" 1.3Vcore @ 4.5Ghz and everything works great, now the thing is: as i don't need more than 4.5ghz... i try to lower voltage and test stability. So far i'm at 1.278V and it seems stable but i've used Intel Burn test on Very high for quite some time now (on previous rig, i mean) and i would like to be sure that my voltage is stable. Anyone with advice on testing stability of Haswell-E, or advices on Vcore tuning would be warmly welcome <3
http://www.ocbase.com/ OCCT Put it in Linpack Mode tick AVX, Use All Logical Cores, 64 bit Set it to 1 hour (no idle time or end time put them at 0) Also set it to use 90% free memory to push the memory controller This will see if its stable, nothing will heat up your CPU like AVX linpack. Another good tool is ASUS RealBench Download that here: http://rog.asus.com/376212014/overclocking/realbench-v2-4-launched-with-x99-support/ Dont bother with the stress test in this, just use the benchmark tool and put it on a loop (around 5 or 10 loops should do). This will stress PC out with real world applications to show you how it will cope under heavy multitasking, etc. Great program.
Well, OCCT did his job: BSOD after 25min at 1.28Vcore. No good surprise there. Thanks RedDawn ^^ Edit: i was in adaptative Mode... guess i can start all over again... !
It's all about Silicon Lottery..My 5930Kbefore can only do 4.3Ghz @ 1.32v..Now I'm happy with my 5960x with 4.5Ghz @ 1.24v..
well, thanks for advices, spent last 2 days on it, and results are quite overwhelming. As usual, " i dont need more than 4.5ghz.." you start tuning and can't stop until you got it all x) My only letdown was on Cache Cpu Ratio. i can't push it over 3.5ghz, so maybe my ring/Cpu cache voltage is all wrong but it's fairly low :[. final result (don't mind the temp , it's after some benchmark, i'm at 20-23° idle): http://valid.canardpc.com/x0qpsp
