While I do not sober up - can you explain to me from where the 10-degree difference? Prime95 produces all the time almost the same load (power), so how is possible that your temps jumps around? ( doh.gif must to be because you are on the bus)


It does not produce a static load.

I say almost ! If you compare with some regular app is static biggrin.gif For change in power consumption you have to wait at least 10 min which can't explain temperature jump's.

Hi again,

i enclose pictures with another successful attempt of 5 ghz p95 i7 3930K 12 hour stability test. This time i used regular llc settings for cpu and vccsa. Vcore value in bios was 1.58V ( offset ) and during load 1.49-1.53V. Ambient temperature was 23C and maximal core temperature 79C.

ok ive been reading this forum all day and playing around with my 3930k... when i set LLC to anything and boot my pc i can boot fine and run stable idle under 5ghz cpu-id shows running at 5ghz and everything but when i go to stree test the core speed dials down to as low as 3.7 and fluctuates between 3.7 and 4.4 ghz as soon as i turn llc off it will stay at 5ghz but crash before i can really get into the stress test long enough to see if it fluctuates... i cant find why its doing this any help is greatly appreciated...

Motherboard is the ASUS Rampage IV Formula

thanks!

OK its not LLC it has something to do with either temp or voltage cause as soon as I push the voltage over 1.45 its like a safety feature kicks in and won't let it stay at those voltages to get 5ghz it will dial the clock back down I've turned off every feature I can think of all the c power options Intel thermal step up everything but can't seem to find out what is causing the dial backs any help would be greatly appreciated as this is giving me a head ache

Hi Marcus,
i need more informations to help you. What is your pc configuration? What cooling do you have? What voltage do you need for 5 ghz? What LLC settings and power options in bios do you use? What are cpu and core temperatures on cpu load ( if you have this data ) ? I had a similliar problem with my attempts to overclock 3930K a while ago and in my case the problem was bios. I flashed bios again and the problem was resolved. I don't know if that advice will help you right now.

Ok my configurations as far as settings arent solid yet obviously but to get 5 ghz i can boot at 1.42 vcore with and llc of ultra high and it will run but when i run a stress test thats when the dialing back starts. As far as power options i turned all of them off which include all the c state power options the surge protection everything name some more if i missed any please... but i turned of all of them to c if maybe they were the cause still the same thing but the same thing happens. As far as cooler i have a H100 with 4 fans doing a push pull and strouds between the push fans. Temps get around 85 degress C. It seems that if i get over a certain Vcore or something it causes the cpu to throttle back. thanks!

1.42 V with LLC on ultra high is maybe enough for prime 95 stability with good chip, low ambient temperature, high end water cooling system and cooling for VRM area on the motherboard. When VRM temperature reach critical value cpu throttling will start. It appears that this happens in your case. What application do you use for stability testing?

I've been using folding at home Intel burn test an a program called occt I believe is the name of it. Have yet to get a stable test in those settings so haven't bothered with prime 95 yet. What exactly is VRM? And how do you track the temperature?

It's part of the motherboard ( usually near cpu socket area ) that provides the appropriate supply voltage to the cpu. It gets very hot with high cpu overclocking. Don't know about ASUS Rampage IV Formula software suit, but on Asus P9x79 motherboard there is no application to track VRM temps with. You have to do it with temperature probe.
