Help to stabilize my OC i5-4670k

Hi guys,

I put WC in my PC and i need help to stabilize my OC where's my specs:

PSU: Corsair CX750
Board: MSI z87 MPOWER
CPU: Core i5 4670K (delied with direct die)
MEM: 2x G.Skill tridentX 8GB 2400Mhz CL10 / 2x Kingston HyperX Predator 8GB 2400Mhz CL11
GPU: Sapphire R9 290 4GB TRI-X OC

WC:
1 RAD Mayhems Havoc 360MM
1 RAD phobya g changer 120mm
1 universal gpu block
1 universal CPU block
1 pump SC600 DC 12v

Well, i post down picture of my settings and a print with 2hours linx the temps are ok at 1.35V and 4.4Ghz 80º max, but in Prime95 after 3/4 hours in blend my PC reboot or crash, i try down to 4.3 ghz but the same, what i can do? can you check all settings of my bios?

Follow the basic rules of overclocking.
Bring your cache and ram down to x40/1.2v (manual) and 1333/1.5v or 1.65v. Use manual/static vcore.

Not sure exactly what Linx does in the CPU but if it has AVX it will cause your problems on Haswell.
Use Prime95 v26.6:

Enter a custom torture test as follows for core speed:
1344k to 1344k
Run FFTs in place (no ram)


I let it run for about 30 minutes, once I've found a core speed/voltage I'm happy with I'll run Large FFT for an hour or so to make 100% sure it's stable before moving on to cache.
I run Large FFT for another hour to get cache speeds finalized.
With the ram I'll run 448K to 4096K, don't run FFTs in place, use about 70% of your ram.

Once I'm happy with everything I'll run Blend for several hours so it runs a wide range of sizes but it's not necessary if you're OK with MAYBE crashing in a game one time. If you don't wish to run Blend for a long time but you can't risk a crash simply add 0.005v or so to vcore and cache when you enable Adaptive/Offset.


Edit: I'd recommend using HWinfo so you have some idea what your voltage and temps are. Core temp is very limited and CPU-z doesn't show your vcore, cache, input voltage plus everything else like the temps of the VRM, SA/I/O voltage and so on.



Set your input voltage to 0.5v over your vcore and enable your board to use more current.

thank you for the reply, i dont understand to much this settings are a friend help me but i can not speak to him at the moment, can you tell me what I need to change in my bios in order to understand?
I'm really thankful for the help, and sorry if my english is bad :/

I did.
Lower ram to 1333, lower cache to x40/1.2v then go for core speed and clocks.
If you don't know what I'm talking about you need to learn as all this is basic OC knowledge and I'm sure you can find a guide in any language if you look.
Not sure how well Google translate would work but here's the best guide I know of:

@white owl thank you, is this what you said? i read all the guide: (i dont said but i have my cpu delied with direct die cooling, without ihs)

i think im right but check please before do the test's with prime95, the temps are very good i think




if the changes are right the results after 30min prime95, in custom torture 1344k to 1344k and run ffts in place
