i5 2500k @4.5Ghz 1.344 vC [Pretty much set!] - Page 2

post #11 of 36
I got my 2500k at 4.5Ghz/1.28 vcore as well but I would say it's just a good chip.
I once saw someone could get his chip at 5Ghz/1.34-1.35v and hell that would be golden.

Oh and yes, I do recommend at least 6-8 hrs of prime.

I said it was stable? If I did I'm sorry, I meant stable into the OS and some quick gaming. With wrong values it would just pop a bsod instantly. Dont know if Prime really is so reliable, some people test 18 hours with prime and end up bsoding at the desktop. This CPU world is crazy.



Oh I see! Leave the ratios to 45 on all cores then is that right? Thanks!

It's difficult to call any chip stable without properly testing it.

Prime is a decent method to check your chip's overclocking stability, and I've found it particularly reliable. The only time I've ever had a BSOD after doing 18+ hours of Prime is when I have another component that's bad. Memory issues, for example, won't always be detected by Prime as having errors, but your system will definitely notice it relatively fast by giving you a BSOD code.

That being said, it sounds like you have some of your energy saving settings turned on if your chip's multiplier/vcore is increasing at load. Adjusting the load-line calibration will also help with v-droop, though I'm not sure what particular levels of calibration your board has.

It has up to 10 levels! Not sure on whats vDroop..care to educate me?

Not sure what energy saving feats your saying, will dig into the bios.

The vcore was actually lowering at load, which was weird tongue.gif

Argh! My VC is dropping at Turbo!!! Which is causing core 1 to fail!

Ah... After some reasearch apparently this is the vDroop! Don't know which level to set the calibration too tongue.gif. I'll got with 5 and see if its improved.

Is it normal? I boot with 1.306, when at full load it drops to 1.27. What the hell is going on? Can complain though because temps are outstanding

v droop/vdrop like mine. i set llc on (Line load calibration on) and keeps volts thare dont drop, drop volts=bsod.
My cpu need 1.275 volts for 4.0 ghz Golden nope (x58 chip) 4.2 need 1.35 Never higher.

Golded 2500k or 2600k are HIGH muilt chips. like 53+ On older chips was volts ya with new chips it nice, But my i7 X58 drains 100watt more.

More on point LLC i GOOD. Prime 12-24 hours on SB chips to find it stable. Or fold 24hours. Just because u can boot into windows dose not make it stable.

Vdroop is when the CPU voltage drops lower than the set values in your BIOS during load.

The Load-Line Callibration pretty much allows you to adjust by how much it drops. If you have 10 levels of it (like I do), then setting it to 5 will pretty much keep the voltages at -.1 of what you have it set in the BIOS.

However, at that level, your voltage will remain consistent and never drop even while idle, so setting it to 5 is a nice way to check what exactly your system's vcore needs to be while under load to be stable without having to go in and out your BIOS to check exactly what your settings are while in idle/load.

I hope that made sense.

That being said, when I'm not overclocking through turbo, I generally have the following settings turned off/on:

Real-Time Ratio Changes in OS - Enabled
CPU Enhanced Halt (C1E) - Disabled
C3/C6 State Support - Disabled
CPU Thermal Monitor - Disabled
CPU EIST Function - Disabled

Everything else in that tab I leave at auto (excluding the multiplier).

It's boot stable biggrin.gif!

Jk. I don't have on or off LLC, just level 1 to 10. Will test it out. Meh I just got excited because I'm a noob who doesnt know nothing about OC. I'm learning now..
Sorry if I said anything messed up to anyone frown.gif

I'll do this exact same settings and see how it goes.

I tested it vCore is at 1.344 according to ET 6. Which is exactly what I wanted smile.gif

Temps on IBT: 62-66-69-66

Pretty good considering I only have 2 case fans, one 200mm on the front which honestly doesnt move too much air and the 120mm exhaust, my hyper 212+ only has one fan too.

Wut? Maybe I'm misunderstanding something here.... I have turbo off and run at 4.5 24/7. Turbo is used when you normally want to run a lower clock and want higher clocks under high loads.

It worked either way here. I left it on for energy savings. smile.gif
