Stabilizing 4.5GHz OC- 2500k

post #1 of 20
Thread Starter 
Back again! I've been getting 124 BSoD errors when I am idling. Perfectly stable at load, but idle gives me the most trouble. I tried lowering my LLC to High (was at Ultra High) and re-doing my overclock, but then I read around that others have had idle trouble that wasn't Vcore related.

So I figure I'd open a new thread to try and figure out how to adjust the VTT and PLL voltage to try and get rid of these idle BSoDs.

Here are some pics of my current BIOS settings:













Hmm...Those links aren't working for me. Here's the album. If anyone knows how to embed Imgur photos here, let me know.

I would say increase your Vcore until you are stable.

I'm stable at load. Not a idle. I don't see how adding Vcore would help.

What I do know is that when I boost my RAM speed to the rated 1600MHz, I get 124 BSoD errors. I was thinking that was an issue with the IMC not getting enough power.

try lowering the PLL voltage. I've lowered the PLL to 1,41250V and I've kept it there for all my overclocks from 4,2GHz to my current 4,9GHz. lower it too much though and your system won't boot(just increase the PLL in that case). You should also increase your VCCIO/CPUIO a little bit to increase stability. But lowering PLL voltage really helps for system stability so I would try that first.

Sounds to me like u have vdroop problem. Llc or loadline calibration should help that if u enable (say 75% or so) helped my rig at idle when voltage would try to stoop too low

I'd be tempted to drop LLC another step or even 2, though it would mean re-doing your offset calculation...not that big a deal really, 2 reboots and you're done.

I tried going down to high, but I ran into a weird situation with Vdroop.

I set the voltage at 1.325, then set the LLC to High. When I started stress testing, my voltage dropped all the way down to 1.288. Didn't know how to increase the vcore to fix the severe drop.

However, it DID fix the idle voltage issue.

EDIT: One more thing. Should I increase the CPU Current Capability? It's at 100% now. Should I ramp it to 130%?

The lower you have your LLC, the higher you need to set your vcore. You'll have to play around a little - just remember that your desktop load voltage won't be the same as what you set in bios, and other than that just shoot for the number at desktop you think is right/stable, then test.

Current cap, 140%. It's red. Don't let it scare you.

Enable C1E and Speedstep and leave C3 and C6 disabled and that should do it. If not, then do as keto said and reduce the LLC and increase the vcore to your desired load voltage.

Thanks guys. I'll hand out +REP shortly. I've tried enabling C1E (no help), so I'll keep that enabled and start over trying to set my LLC.
