I5-2500k OC, Have I Hit a Wall?

post #1 of 12
Thread Starter 
Hi, I found this board while doing some searching for a solution to this problem.

I've got a Core i5-2500k with a Hyper Evo 212 cooler and ASRock Extreme3 Gen3 motherboard.

Just with all stock settings (including auto voltage) and setting the multiplier to 45 I get a stable 4.5 ghz overclock. Running prime95 for a few hours shows the voltage running around 1.280v, temps average 50c or less.

I played around with offset voltage and got it to -0.005 stable still at 4.5ghz. With that offset the voltage still stays around 1.280 or less and around same temps. Tried lowing it to -0.010 and got errors in prime95.

So now I've been trying to go up to 4.6 ghz, but every voltage I try, up to 1.380 (I haven't tried going any higher than this) doesn't even boot to windows.

Is it common for one of these to hit a wall like that where it can't go any higher regardless of voltage and cooling? Is there anything else I should try?

Thanks

make sure your PPL or LLC dont remember which one it is is set to level 1 which has the least amount of v droop and make sure has an updated bios cause i remember when those first came out the bios that came with them pretty much hit a wall at 4.5 on all cpus goodluck

Funny... on my ASrock Extreme4 Gen3, level 5 has the most Vdroop.

OP, I would enable Internal PLL voltage in the BIOS. Did you get a blinking cursor when you tried to overclock to 4.6?

He couldn't get it to boot into windows on 4.6. Or do you mean in the bios?

To elaborate, when I tried to raise my multi past 44, I would get a blinking cursor (a blinking underscore that goes on forever) right after BIOS and before Windows startup. Enabling the Internal PLL voltage seemed to fix it.

I just got my 2500K as well and I'm still tinkering with it.

OK I've tried everything suggested and made no progress.

I updated the bios to the latest version (1.30), enabled Internal PLL Voltage, set LLC/PPL to level 1. I still get no boot at all attempting 4.6ghz with voltage all the way up to 1.380v. Running 4.5ghz voltage at 1.280v is stable.

In response to the "blinking cursor" question, my monitor doesn't even register a connected PC. The PC fans spin up but the monitor stays in the mode of searching for a signal.

Any other ideas?

Oh THAT cursor, I thought you meant like a mouse cursor. My bad
