i5 4670k overclocking help needed!!!

[Khan1786]

HI, im having lots of trouble from this piece of junk i5 4670k, I cannot get it to stay stable on prime 95, it crashes after 15 mins with a BSOD, temperatures are fin, max is 83c, the funny thing is it can pass intel burn test and intel extreme tuning utility but not prime! I've set the voltage @ 1.32v, vciin voltage @ 1.950v, ring ratio @ 3400mhz, any suggestions will greatly be appreciated, and yes I will pick a 'best solution' too!

specs:
- i5 4670k cpu
- msi z87-g55 mobo
- corsair h100i cooler
- 8gb ddr3 Hynix memory @ 1333mhz
- gigabyte r9 280x cpu
- evga 600w psu
- coolermaster haf xm case

thanks!

Some programs may have different techniques in over clocking your cpu. Some cpus may also clock differently, even with the same brand. So, if so, try using while doing intense applications and see if it Blue Screens again. Prime 95 may be the culprit, I am not entirly sure, but I am pretty sure it is a software problem, or your cpu doesnt like the overclocking.

Lower down the voltage a bit. That could be the culprit 😉

OMG 1.32VCore! Set it down to 1.25-1.28V and I hope you're not taking your CPU beyond 4.6GHz. VCIIN is fine. Disable LLC. Try on Auto to 4.5Ghz stable and note down VCore. It should not go beyond 1.3V.

hi thanks for your response, about the voltage, I put it @ 1.34v and it is still unstable, however I downclocked it to 4.30ghz and it was prime stable for an hour @ 1.210v, strange

You simply don't have to take VCore to more than 1.3V at any cost in regular conditions. Put the VCore manually to 1.25V, and OC to 4.4GHz, then try 4.5GHz but don't go beyond that as it's likely to BSOD. You don't have to get the VCore up, but rather down.
Firstly, try to get everything on Auto and set multiplier on 40, you should get to 4GHz easily. Then enhance the multiplier and take down VCore reading. When VCore goes beyond 1.3V, don't OC further, disable LLC, manually get the VCore to 1.25-1.28V and check for BSOD with Prime 95 for atleast 1 hour.

4.3 @ 1.21v seems stable, tried 4.4ghz @ 1.250 = bsod

Try getting to 4.4GHz with 1.28VCore.

im tired with this junk, i'm just gonna use a xeon e3-1230 cpu that I bought for £80, and sell this.

Your wish :3

The 4670k is not a great OCer, but it OCs to 4.6GHz stable quite a few times. 4.5GHz is relatively easy and that's why I was guiding him through the process to get the best of what he has, and not condemn his choice.
