Gigabyte G1 sniper Z87

[thrangz]

Hello, i recently bought some new parts to build my 1st DIY pc.

My speclist is:
CPU:Intel i5 4670k
Mobo: G1 sniper z87
Ram: 8Gig(2x4) corsair vengeance 1600kit (transfered from previous pc)
PSU:Corsair RM 750W
GFX: gtx 770 WF
Corsair 100i

So when i decided to start tuning and overclocking the pc following Tom's guide i start to see some issues.
To start when i was trying to find the stock volts for the cpu i noticed that the value at cpu-z wasnt going down even if i had all power-saving features on.
After that i start working with small steps upwards starting at 4Ghz with the mobo stock-auto volts.The point is that i couldnt manage to keep it stable at any clock with any amount of volts it would freeze or blue screen with the 0x3B code.
I asked a friend about this and he suggested me to up the ram voltage abit.
to clarify this my ram is rated at 1600Mhz 9-9-9-24 at 1.5v
After i tried raising the Ram voltage to 1.65 i managed to run a quick dirty oc at 4.2 at 1.2 volts for a 45mins.
I also know that i may have lose the silicon lottery badly and have a very bad cpu but i thought that at least i should be able to run my memory at rated speed and voltage.
Any chance this is a Bios issue and an update to the latest one could fix it instead of bad luck at the lottery?
Also occt was acting a bit weird it was freezing during testing for few seconds and then it was ok.
I forgot to mention that i tried stress testing the pc at stock and got blue screen twice with the same 0x3B code when i pressed the off button at occt.

Thanks in advance for any help!

The problem is - as you said- you are running stock/auto volts. You need to set this up manually as it is the only reliable way. Auto will screw everything up.

Just leave the ram at rated speeds. For a small overclock ram won't really be an issue. Its only when you are really trying to push every cpu clock possible that it needs to be lowered.

 

[thrangz]

No no no you missunderstood. when i say stock-auto i mean i set the auto value manually.

 

[NeverBackDown]

Did you start at the stock clock and gradually lower the volts by a .05 interval?

 

[thrangz]

yes and once i found the sweetspot i then put a x40 multiplier and the starting stock volts as Tom did on his video.

 

[NeverBackDown]

you can't just go from the "sweet spot" volts for stock clocks and jump up to a 4Ghz OC without upping volts if that is what you are saying?(sorry don't remember the video been way to long).

What you should do is up the multiplier by 1 until windows won't boot. Once it fails to boot up the volts by .05 and so on and so forth. After 40 i would personally then stop and find a stable 24/7 volt level. After that do it all over again until you want to stop. For gaming though anything after 4.4ish doesn't really help.

 

[thrangz]

Sorry if i dont explain it well enough. Let me try again.
i started lowering the volts until i reached the sweetspot which was stock frequency and 1.033 volts. Then i raised the multiplier to 40 and set the amount of volts that the motherboard thinks is the stock volts ( in my case 1.14)

 

[NeverBackDown]

And its not stable?

 

[thrangz]

no it wasnt stable until i upped the ram voltage from the rated 1.5 to 1.65.
Before raising the ram volts i tried xmp and manual timings and 1333mhz

 

[NeverBackDown]

Ok keep the ram at the xmp specs. Just keep upping the vcore on the CPU to get it stable.

Just a quick question but do you have LLC enabled and at which percent/setting?

 

[thrangz]

llc for cpu vcore is not adjustable in this board.. but is being working great i have no vdroop at all.

 

[NeverBackDown]

Have you tried upping the vcore yet?

 

[thrangz]

yes after i managed to run the 4.2 with 1.2 vcore and the ram at 1.64volts i tried 4.4 up until 1.275 with no luck

 

[NeverBackDown]

Again try to keep ram at the rated specs. There's really no need to up it. Just try to keep uping the vcore until you can get a stable 8 hour stress test. If upping the vcore won't help(with memory at 1.5volts) no matter how high you go then your CPU memory controller is weaker than average and needs to be upped in order for the CPU to run at higher clocks. I personally would go as high as possible without needing to up the memory volts. No sense in stressing the ram or CPU for a mere 100mhz clock boost.

 

[thrangz]

i see. shame i thought that 1600mhz was considering basic speed for haswell.

 

[NeverBackDown]

Its basic for the memory yes. They are designed to allow the memory to run at that speed.

 

[thrangz]

correct me if i am wrong please but both the cpu and motherboard accept 1600 speed without O.C indicator. If my the memory controller cant handle the native speed of a rated memory then maybe something is wrong with the cpu?

Only problem is you not knowing how to set up the bios sadly dude

 

[thrangz]

i watched your guide many many times in case i missed something and i followed it to the letter. The issue exists even if i dont even touch the memory at all ( default 1333)

 

[tinytomlogan]

Try an updated bios and new memory - Ive never found an Intel CPU that couldnt do 1600
