Does this overclock look ok?

Hey all, I'm new to overclocking and have been reading some of the threads and fiddling around and just wanted to make sure this was ok or if there was anything you guys would change. If you do recommend changing something please be aware of my noobiness so speak to me like a child :)

Specs:
Intel i5 3570k
Asus Z77X-UDH5
8GB Patriot Black Mamba 1600MHz
Corsair H60 cooler

Overclock:
Bus Speed: 105MHz
Multiplier: 43
Voltage: 1.2
Clock Speed: 4.515GHz

I havent touched the RAM as to be honest the whole thing confuses the hell out of me, currently running Prime 95 and no issues so far after an hour and a half, temps are maxing at 57 according to CoreTemp.

Any advice is much appreciated :)
 
That looks very good actually. Props for the BLK clocking for the bandwidth win. Good volts and temps for 4.5GHz too.

Very good for a noob ;)

Yep, as you have increased the bclk it has increased your RAM frequency

Is that a good or bad thing? Lower numbers = bad in my mind :p

Edit - Also just tried to run Passmark 8 and it crashed during the 3D graphics test, so looks like it isnt stable after all. No BSOD it just failed to find a display, computer was still running.

I might drop the bus speed a bit and up the multiplier and see if thats a bit more stable, according to CPU-Z and CoreTemp it was using less voltage than I had set and the temps were not an issue. Not sure why its crashing.

Im guessing that is under load, if so thats Vdroop kicking in. Raising you LLC will combat that drop. That could be why it's crashing..

I had my 4.5 Stable in prime but playing a film crashed it, added a touch more vcore and it works fine.. That may be your issue..

You did well, normally BLCK overclocks don't work well with sandy/ivy.. :)
 
Ah it's crashing! Wll in that case it isn't the best :p

First course of action, as you have surmised, is to drop the BCLK to 100 and put your multiplier up to 45 and see if that fixes it. The cause of those crashes could be either your RAM being overclocked or the BCLK itself, since it's tied to other things like PCI E lane frequencies that aren't too fond of being overclocked. Small BCLK overclocks are a good way to squeeze extra bandwidth and MHz out of your system though, so it's admirable to try!

If you are still getting crashes after that, then it means your cpu needs more volts. The drop in voltage in CPU-Z is correctly described above as vdroop. That's the only voltage you should be concerned with (the CPU-Z one). Raising your load line calibration setting will compensate for the drop in VCore under load, but you don't want it to be so high that it is spiking way above what you set because it won't be as predictable to overclock. Lastly, you can try raising the Vcore a bit to get it rock solid (keep it under 1.3V if you can, 1.34V is the max I would go to for 24/7 long term usage, but you won't need that much for 4.5GHz).

If it turns out the cpu just needed more vcore, once you get it stable you can try raising BCLK a few notches (dropping the multiplier to compensate) and start overclocking that and your RAM (by extension) to squeeze a little more performance out.

Great thanks for the tips guys, my new power supply for it arrived today so ill fit that first before I attempt anything further. Whats is the LLC though? I dont remember seeing any mention of it in the BIOS settings, is it known as anything else?
 
LLC is load line calibration. It compensates for the drop in voltage that happens when your cpu is under load by putting more volts in when the cpu is loaded. The different settings decide how much extra it puts in, so you want a setting that closely matches what you set in the BIOS when your cpu is running prime95, or just slightly above. Once that's correctly set you can start following the procedures above to get it stable. Obviously, you may need to change some settings once your LLC is lined up because it'll change the voltage going into your cpu. You may need to raise or lower your Vcore until it's showing close to what you had in CPU-Z.

It's easier to find if you get away from the flashy 3d BIOS and just use the good old fashion blue writing on a black screen.

If you're using the 3d BIOS then you'll find it on this screen

I can't remember where it is on the 2d menu, but dig about and you'll find it. Either that or consult the manual.

Cheers Devrij, found the setting and put it on "standard" which seems to be the lowest, CPU-Z now says my voltage is 1.2 which is what I have it set to so im assuming thats correct.

Edit - Under load it drops to 1.14v, rereading again and it would seem I need to raise it not lower it, herp de derp!

It's ok, I only learnt that the other day. I am also in a similar boat with overclocking. I need to get a decent heatsink/fan for my cpu. Intel stock is not good.

I'm at 4.4ghz but have literally only adjusted the multiplier. Nothing else.

You're at 4.4Ghz on stock cooling? That can't be safe :p

And UEFI Bios is better than both the "3d bios" and old fashioned one :p
 
Right i have it stable at 4.5 now, it seems raising the bus speed is a no no, so ill have to play about with smaller increases. What temperatures are safe? Now that I have the computer case properly assembled the temperatures have crept up, however ive got 3 more fans still to connect when my splitters and controller arrive. Nudging 80 at 4.6 on a couple of cores so ive stopped Prime 95 as this seems a bit hot for my liking so will drop the voltage in the mean time.

It's only running at that when I prime95 test it or use games. I'm not sure I changed anything about the speedstep or whatever it's called where it boosts the speed from idle to turbo

I will be getting a heatsink/cooler/fan combo in 2 weeks
 
Sorry my bad from earlier today. I'm at 4.2ghz


BCLK - 100.12mhz
MEM FREQ. - 1601.94mhz
CORE TEMPS - 44c roughly on all 4 cores
MEM - 9.9.9.24

CPU VCORE - 1.092
DRAM VOLTAGE - 1.512

Think I have it stable at 4.6 now, temps are still a bit of an issue I think, but im adding more cooling soon so hopefully that should control it a bit better.

That doesn't sound good..

I hit high 60's at 4.4 on my H50 and stopped,,

It sounds like 4.5 is your limit mate.
