So, i have a Z77X-D3H in revision 1.0. This model has a 4-pin ATX-plug for the CPU. I was surprised, this mainboard don't have an 8-Pin EPS-Plug. At the current my Core i5-3570K is overclocked to 4,2 GHz with a VCore at 1,152V at Prime95. The VID is at 1,12V. Well, the 4-pin ATX-Plug can deliver max. 150W, so i understand.

In your forum, a user had a Z77X-D3H, too. Of course, he overclocked his system, but the 4-pin Plug was burned: http://www.overclock.net/t/1326667/gigabyte-ga-z77x-d3h-v-1-0-major-failure

My question is, how far i can choose the VCore, if i want to Overclock my CPU to 4,5 GHz? Am i safe with current settings?

PSU is a bequiet straight power e9 480 watt

Can someone please answer my question?

From what I know 4 pin can deliver 22 amps which is 264W. More than enough for any overclock. His plug fried not because it couldn't deliver, but rather because it was defective or something wrong with his PSU.

Also D3H rev 1.1 has 8 pin connector.

Thanks.

timings

they give better score in aida64 bench buit could cause a little instability maybe

Thx for your reply. smile.gif Are you also sure that it can otherwise cause no damage? I must not make me worry?

But the revision 1.1 have a 8-pol ATX. My question is about the revision 1.0 with a 4-pin ATX.

There is always an increase risk of damage to your computer when overclocking. Only you can decide if it is worth the risk.

As to whether the 4-pin atx connector on the motherboard is capable of handling the additional power requirements under load at a particular OC is a question better asked directly with the motherboard supplier. My guess is that you likely will not have a problem due to the connector limits but may have problems with your power supply being able to maintain the 12v (+/-) under load. Without knowing your system specs, it is impossible to say whether your power supply is up to the task of performing well at high oc's.

Yeah, I know. I was just saying that because it's your house that's going to burn down, not mine thumb.gifJ/k.... (Click to show)

You'll be just fine, from what I've seen the 4-pin connector can supply 250W and honestly if you suck 250W through the motherboard alone then you'd have a bigger PSU to start with which you obviously don't need. It's a 77W TDP'ed CPU right?

For a more detailed analysis checkout Sin's review of the G1.Sniper M3:
http://www.overclock.net/t/1299900/g1-sniper-m3-review/0_20

His testings should definitely reassure you, as DeXel said I guess that the problem which happened in the thread you mentioned wasn't related to the fact that it's a 4-pin connector.
