i5 2500K - Can't get this thing stable! Help!

post #1 of 29
Thread Starter 
Alright, so at this point I'm about ready to puke.

I'm really getting sick and tired of trying to overclock this thing and spending weeks trying to get it stable.

First off lets start with my goals.

4.7 GHz
any voltage under 1.5
12 hour Prime95 blend stable using 90% RAM (sandy stable club)
temps under 85* MAX (80 preferably)

Alright next, screenshots. Here is my CURRENT 5 hour stable Prime95 blend settings.

I've ran these settings a few times at around 5 hours I get BSOD 124. I've ran 15+ hours on battlefield 3 with these settings.







Ok so, I've tried MANY things to get this stable and I'm completely unsuccessful apparently. I've tried upping the voltage, lowering the voltage, changing multiplier and upping/lowering voltage, lowering PLL voltage, upping VTT voltage, changing RAM settings, enabling/disabling random things like c3/c6/thermal throttling/PLL overvoltage/c1e ect, ect ,ect... I've basically tried it all and some how I can't get this CPU to run longer then 5 hours on Prime95.

I REALLY NEED HELP!

I don't know why I cant get this stable. I've pumping more then enough voltage for any multiplier I set it to. 1.45 volts for 4.7 GHz I've never seen and I understand all chips are different but there is no way my chip requires more voltage. It must be something else!

I'm lost for words lately and I feel like just giving up. All I want is 4.7 GHz stable. I don't even care for 4.8, 4.9, 5.0 GHz. I just want stability at 4.7.

Please enlighten me with what I could possibly do to make this stable. PLEASE!

Side question: I included my fan screenshot there because I've had a question I needed answered for a while. Is it possible for me to raise those speeds? The side fan of mine seems a bit slow, not sure, but I'd love for them to go faster. The settings they are on is maxed I can go. Full on and level 5. Anyone know?



BTW: I've read almost every post, sandy stable club, all these posts that others make, guides, ect, ect and they don't help. I've tried so much.

System is in sig.

Flash to the latest available bios, 1.10, load optimized defaults and give it a go again. Set it to the multiplier you want, load up windows in offset voltage mode (try this instead of fixed) with +0mV, and see what load voltage is by running prime95. Then adjust the voltage +/- as necessary. Set load line calibration to the next highest level. I'm not sure how your board works, but if level 5 was the most extreme and doesn't budge at all (sometimes even increases), set it to level 4. My board calls the two highest setting extreme and ultra high I think, and I think I run the ultra high because it works the best. If you're still having stability problems increase the VTT to 1.15v but that shouldn't need to happen.

He's already tried helping me, rofl.

1.10 bios isn't compatible with my mouse/keyboard. I've already tried it.

Also, I've gone to defaults and its perfectly stable, but I want 4.7 GHz. The voltage isn't the issue as I've said. I'm running more then enough volts for 4.7 considering I can run Prime95 at like 1.420 volts at 4.7 GHz. If I changed LLC to anything from level 2 I get way too much voltage spikes. Level 2 is my sweet spot, anything other I get spikes from 0.030-0.050

EDIT: Also tried raising VTT to 1.15

You tried setting that VCCIO to 1.1? That helped me with BSOD x124 every 2-3 weeks and i was passing prime95 12 hours (sandy stable) and intel burn testx5 maximum. Also do you have a setting to enable internal PLL Overvolt? Also i had to bump up my VCORE from 1.325 to 1.330 and no 2-3 week BSODS x124 now. so i guess the best test is real world testing over months. Alot of the time i can tell when a OC isnt stable just when i boot up and see the CPU acting less stable than normal. (Slow from lack of power)

So your settings are fine for 15 hours+ during actual real world use? but it fails after 5 hours + on prime?

Who gives a monkeys. It's stable doing what YOU USE IT FOR.

Have you tried enabling spread spectrum? I'd also say raise your LLC and set your cpu voltages using offset voltages. It could be that your chip just isn't capable of being fully stable at 4.7.

I don't mean to offer half-help but I don't know your mobo , but I would up the LLC to the highest or next to highest and I would find what people have their C-States set to that have had success. I know with my board that having C3 or C6 auto or enabled I get weird bsod's and you may need to disable some of them.
