2600K OC BSOD Situation - Page 3

post #21 of 47

Thanks for that. I thought about it and realized that I honestly don't do enough to require Hyperthreading, and if I can get more clocks out of my CPU with less Volts, that should make up for it.

So...I disabled Hyperthreading and ran at 1.35V Vcore BIOS.

When I ran Prime 95, I didn't instantly crash, so that is a good sign. However, interestingly enough, my Vcore plummeted from 1.336V Idle to 1.280V under load. Does this mean I could actually overclock higher without Hyperthreading and the same voltage?

It looks to me like Vdroop Offset Control is disabled.  I mean, otherwise I don't think it would droop down that far.  If it's enabled, then try a higher percentage.

 

Either way, having Hyper Threading enabled kind of lightens the load for the CPU in a sense, and that's why a lower core voltage can be used.  However, I am not expecting 1.280V to be stable.

I would say you have too much droop and its making CPU OC unstable.. 

 

 You need to higher level power options to minimize droop more.. this should allow you to actually lower vcore as it will maintain a tighter margin between idle and load transition. Set 'vdroop offset control' to at least 75%

 

**turn EUP to OFF

**turn off 'CPU Phase control' unless your enabling it for power saving 

**turn 'Overspeed Protection' to disabled

It's enabled I believe by what I'm going to describe now.

I followed what CL3P20 suggested and changed those settings. Set Vdrop Offset to 75%, Disabled EUP, Disabled CPU PHASE, Disabled OVERSPEED PROTECT.

Also, my Power Settings were already set to Maximum Performance.

So I tried running Prime 95 again. I was idling at 1.336V, but once I ran Prime 95, my Vcore dropped to a fluctuation between 1.304V ~ 1.296V, but staying more so at 1.304V.

Should I increase the Vdroop Offset to 85%?

Yeah, let's try 85% and see what happens to the vDroop.

Full load Vcore fluctuates between 1.312 and 1.304, although it spends more time at 1.312.

Ooo, that's better.  What does 90% do?  Or if 90% isn't an option, then 95%.

Actually I was wrong about the 85%. It was 87.5%

So it's 25>37.5>50>67.5>75>87.5>100%

Should I try 100%? Any risk involved in doing so?

With this board, I don't know.  I am surprised that 87.5% isn't resulting in the vRise I described before because I am used to seeing the Z77 chipset doing great with vDroop at about 50% for other boards - even with Sandy Bridge CPUs like yours.

 

I admit that I'm a little concerned about the VRM's temperature, so I'm leaning towards staying at 87.5%.  However, it would be fine to test 100% for a moment just to see what happens to the vDroop.  Based on the behavior so far, I'm expecting pretty much no vDroop at all.

Tried it at 100%. On Full Load, my Vcore is fluctuating wildly between 1.328 and 1.320. What would you recommend is the best course of action?

Also, not sure if it's of any concern, but right now my Vcore dancing between 1.344V, 1.336V, and sometimes 1.328V constantly. Just on my web browser. Not sure if that is of any importance.
