Increasing Overclock

[L A]

Thanks for the recommendations! How much larger than the 212 evo are they? Im just worried that they might not fit...

Which setting do I increase to increase the VCCIN? Also where do you look for the vdroop? Do I need to watch out for mobo temps?

What's your take on increasing bclk? It seems my CPU refuses to take a 48 multiplier and so I'm thinking I could try a small increase in bclk.

Sorry for all the questions >.<

 

First of, all my recommendations will fit your case. Your Ostrog has a height clearance of 185.3mm. The Bequiets are 163mm, Cryorig is 168.3mm, and Noctua is about 160mm.

 

You'll have to check your MoBo manual about which setting is VCCIN. I think each Motherboard company names it differently (UGH so frustrating), for instance, my AsRock Z87E calls VCCIN VCCIN. It's simple and I like it. Evidence of Vdroop was what @kurahk7 was saying. You're feeding the CPU 1.4ish volts (Check your CPU Vcore) but it's only getting 1.26 (Check your VID).

 

So bclk... I honestly don't like touching the base clock to be honest. But if you're gonna do it, I've read that most CPUs can only go up 5% of their base clock number--any higher and they get unstable. Basically, increase with caution. Also, try to put your RAM back to stock settings if you haven't already.

 

No worries about questions man! We're all friends here.

It's better choose

 

NZXT Kraken X61 cooler.

Ok, thanks for making sure they all fit! I'll look into getting one as a good CPU cooler is a pretty good investment anyway.

 

I looked into what setting i should use to combat vdroop and I found that its through a LLC setting. The problem is that is already set to ultra high (2nd highest setting) and its actualy causing my vcore to be 0.2 higher than what I set. I'm really confused as to why my VID is so low... 

 

Hm, ok. I was considering setting the bclk at 102-3 but I read up on it more and it seems it can damage more than just your cpu so I'll leave that for a last resort. Also, what do you mean by stock settings for RAM? I'm running them at 1600mhz which is its factory setting. The only thing is that I had to change the setting to XMP as it was runnign at 1333mhz earlier. 

 

Thanks bro!

No prob! Invest in a good cooler since it keeps your cpu healthy.

 

Load line calibration is what I had at the tip of my tongue when I was typing that reply! Yeah, LLC is helpful here as it compensates for Vdroop. What's your VCCIN/Processor Input Voltage btw? That might be too low.

 

Right, bclk can be tricky at times but if you know how to dial it down, you get a much more efficient overclock. I just don't like touching it. Regarding RAM, most people would suggest placing your RAM at it's factory settings and voltage when you overclock. It gives you less problems to troubleshoot when you're trying to figure out why your current settings are crashing. I'd say keep it at 1333mhz @ 1.5v (or 1.65 if that is its default)

 

So yeah, I'm not an expert at this but I love tweaking OC's ever since I started learning about it about 2 years ago now. It's a lot of fun.

Where do I check for VCCIN? I don't see any setting related to that in the BIOS. 

 

Ok. I'll try setting my RAM back to default. I just got BSOD x0A which i read is unstable RAM.

 

I haven't actually put this much time into my overclock before and I have to agree, it's really fun (and a little addicting).

Actually, I think VCCIN is for Haswell chips. But I believe the equivalent for Ivy bridge is PLL voltage. My bad! I had a 4670k when I got introduced to overclocking! So the terms I know are mostly Haswell based. If anyone knows, please let us know.

 

I've been reading your Motherboard's manual and there should be a setting to change that PLL voltage (should be aptly named, CPU PLL VOLTAGE). Now, increasing this would allow you to get more stable OCs. Intel suggests to not go above 1.94v though. Source.

 

But yes! OCing is the rabbit hole of the PC enthusiast community. You can get lost in it but hell it's a lot of fun. I spent 5 months tuning my 4670k (well before it died last month...)

I just remembered I didn't enable the PLL overvoltage setting. I'll try that see what happens. All I knew was that it would keep me pc from sleeping and I kinda wanted to keep that. I have an SSD though and so hibernation should be fnie.

 

Aw how did your 4670k die?

Yeah, try doing the PLL thing. Should work wonders if you don't keep it at auto. Oh it prevents it from sleeping? Huh. Well so long as you're okay with that then good!

 

It died randomly lol. I was doing homework and plooop, PC died lol.

[EpIcPoNaGe]

What's a good cpu benchmark to test the perfomance gains of different clock speeds?

[Godlygamer23]

3DMark 2013, Cinebench, BOINC(not really a "benchmark" per se). In addition, games like Skyrim, Starcraft, etc can be used because they're CPU bound titles. That being said, outside of that, you probably won't see much of a gain.

It actually booted when I input 4.8 so it seems the pll overvoltage setting helped.

Aw that really sucks how'd you determine it was your CPU?

Btw I was just wondering, is your build supposed to be portable? I noticed it's itx and etc.

OK thanks! I just want to see if it's worth going for a 24/7 4.8ghz oc and was thinking that benchmarks would be a good way to test that.

If you set your Windows power mode to Balanced, your CPU should clock down when idling. However, you will need to set some sort of Adaptive Voltage because the voltage will remain consistent otherwise. (If you set your voltage to 1.4, it'll remain at 1.4 even when the CPU is downclocking.)

OK. I'm planning to set an offset because that should decrease the voltage with the clocks

[Blackie Sheen]

Its not likely that you will be able to hit 5 gHz certainly not with any AIO or any high end air coolers. You would have to be having a pretty intense custom watercooling setup which you dont look to be having since those max temps are too high for that. Plus, voltage needed when overclocking increases exponentially so you would probably need voltage like 1.45 to hit that 5 gHz which again will not happen unless you have a good custom watercooling setup with a good cpu block or if you are doing ln2 watercooling

Yeah I was trying to set a lofty goal. It seems I won't even be able to hit 4.8 as it seems my VID refuses to increase. The max VID I get is 1.271 with pll overvoltage enabled.

[EpIcPoNaGe]

Weird. So I found that my 4.7ghz oc seems to be stable at 1.408V (high, yes I know) and so I decided to set my offset. The offset I calculated was 1.408-1.261= roughly 0.15. However when set it and started stress testing, my voltages only went up to 1.384max and 1.376avg. It seems to be stable so far (I'm going to give it a few hours). Why is it that im supposedly stable at a lower voltage than earlier?

Nice! Sounds like my educated guess was right about PLL being equal-ish to VCCIN. So, I determined that it was the CPU after I RMA'd the MoBo. The thing didn't work still so I put in my backup CPU (A crappy G1820 I got from a shady dude) and my PC booted up.

 

Yes! Since I travel a lot (LA -> NorCal, NorCal -> LA) I had my build made with portability in mind. The Prodigy isn't that bad when you carry it around--looks darn nice to boot.

 

So about that lower voltage thing, correct me if I'm wrong but I think your CPU decided it didn't need to go higher than those voltages to keep stable. The offset just sets the maximum voltage the CPU can pull. Keep that testing for 6-8 hours, check if it's stable.

 

What test are you using? I usually use Prime95 and AIDA64.

[EpIcPoNaGe]

That was a good educated guess.

Ahh I see that must have been a hassle.

That's cool! I've always wanted to do a portable/small build but idk if i can give up the SLI option. How are temps in that case though?

I found that the voltage was actually on the edge of unstable. I ended up bumping up the offset more and now it's hitting 1.416 max and an average around 1.4 and 1.396. I had to set the CPU fan curve to turbo though and the noise is quite annoying... Probably should order one of those other coolers.

Im using prime 95 for my testing as I hear it's OK to test ivy bridge with that.

[EpIcPoNaGe]

 

Parts of the prime95 test are bring my CPU up to 93C. It really seems like my CPU is a terrible overclocker as it needs 1.4Vs for 4.7ghz

Sorry, as stated in earlier posts AIO coolers won't fit.

Just want to pipe in here. That's bull, I have used an Ostrog. That thing is a friggin tank of a case and ridiculously well suited to water cooling.

You need to think creatively. Rad up top, fans on the outside, you can fit a 240mm setup in there easily. I have done it, and it worked incredibly well. If you plan it out with a custom look you can fit an even bigger setup.

Probably have a picture of that setup somewhere...

I know you can mount the fans on the outside but I'd really prefer not to as I lay things on top of my case as my desk doesn't exactly have that much room to spare...

 

How would you do a custom loop in this case? I feel like there isn't much radiator space given that the bottom front hard drive cage is riveted in.

The joys of modding, I'll find some pictures.

Also you can put grills on the fans on top to stop things from falling in or little animals from catching curious paws.

Haha I'd love to get into modding but that'll suck even more of the time that I don't have 

I've actually kinda started to dislike the look of the ostrog now. Its a bit too flashy for me but I bought it because of how good it was for the money. 

 

Hm, thats true.

It's a hassle man. It's still in the RMA process >.< I can't join my LTT peeps in playing GTAV!! :<

 

Yes, ITX builds are great man. But if you really want to SLI option, the Prodigy comes in an mATX version (same dimensions just a completely different internal setup). So you get the same size but with SLI. Temperatures of my main rig are shown here, scroll down to the last parts.

 

At least we now know what that CPU's needs. The next step probably would be to back off and put it at a comfy setting until your cooler of choice arrives. If you're willing to part with that 212 evo, I MIGHT buy it off of you! But I understand if you want a back up heatsink.

 

Prime 95 works! 94 celsius is damn hot though. Be careful! I've never seen a 1.4v OC on a 212 before lol.
