On yeah it will be better performance, but you need t ask yourself, is it performance you will see in real life and is amd going to warranty the chip if you fry it?

As for LLC, I am half drunk right now with a bucket of chicken in my lap and 2 beers in front of me. I click johan's link on the overclocking guide. First I seen it. True story. First thing that popped out at me was, and I qoute "If you have LLC option set it to the highest or second to highest. "

Awesome thanks extreme is my highest setting so it seems well.

Yeah I just like having most performance, I don't plan on having this chip over 2 years anyway

Well lol at the rate your going you may fall short of the 2 year goal by about a year and 360 days.

Why is that? You guys said 1.55V is fine and the cooling seems sufficient I don't see any very high temps.

5Ghz doesn't even seem like too big of an overclock the guy in the tutorial OCed a lower bin chip to 5.3

 

[ThE_MaD_ShOt]

What are your temps? under full load and at idle?

What are your temps? under full load and at idle?

As well as core voltage under load and idle.

 

[OverclockNoob]

Ok with antivirus and stuff running in background 22C at idle.

While gaming and opening many applications I have seen it go towards 50C at times.

Voltage is: http://prntscr.com/3gb703

That's with voltage set to 1.55 and LLC on extreme? If so, you need to start by lowering your voltage a little bit and then checking to see if the voltage raises or lowers when you run Prime95. If LLC is on extreme, chances are it will raise. If the voltage stays the same between idle and full load, LLC is set properly. If the voltage rises when you go from idle to load, the LLC level needs to be lowered.
I'm going to be straight with you here. With the amount of experience you have, you need to set your sights to something more realistic, say 4.4-4.5GHz. 5GHz is not a 24/7 stable overclock you will be able to maintain on a H110, period. You're already pushing dangerous levels of voltage through your chip, and you don't even know if it's stable or how hot it gets under 100% load. At this rate, something is going to fry. Have you even checked to see how hot your VRM heatsink on your motherboard is getting? Chances are you're going to need a fan on that as well, or risk frying the board, too.

Thank you for the info this is the kind of information I need.

Ok, so I don't really understand LLC much but I will try dropping the voltage some more.

Just found out how to thank posts sorry about not thanking them before

Alright, here's a quick and dirty explanation of LLC, or Load-Line Calibration:
Basically, LLC is a setting you adjust to keep a variable called VDroop under control. VDroop is a drop in core voltage when the load goes from low to high, for example, you could be sitting at the desktop with 1.55V dead, but without LLC, as soon as you put 100% load on the processor, that 1.55V will drop, or droop. Just how much depends on a lot of things. By raising your LLC in BIOS, you can counteract the droop. Ideally, there will be a setting that keeps the voltage dead constant between idle and load, but this doesn't always play out perfectly. What you're going to want to do to determine the proper LLC level for yourself is determine where your core voltage sits at idle, then apply a 100% load to your processor(we've all mentioned Prime95, you should really download it) and keep an eye on the core voltage. If that voltage droops under load, you need to raise LLC. If the voltage raises under load, your LLC is set too high(which I'm willing to bet is the case here since you have LLC maxed). If there is little to no change, you're on the proper setting or damn close.

I see, but the thing is my system crashes if I try to run prime 95 at 5Ghz

That's what we were trying to say all along. 5.0G is a very lofty goal for anyone unless they're running a serious water loop. The H100 is a decent cooler and will probably handle something in the 4.7 range. When OCing , you can't just plug in numbers andgo. It takes time , start out low and work your way up. At this point you have no idea what is causing the instability. Could be ram/ NB or CPU_Vcore. It's just a shot in the dark.

OH! I see, because before 1.55v only would last 4.6Ghz now I can handle 5Ghz after following that tutorial and boosting my voltage on other stuff.

Before I thought only vcore voltage mattered now I see there are many variables and it is sort of a tough process.

Thank you so much, so what settings do you suggest I should do to start getting my overclock to a reasonable/stable one

 

[Johan45]

OK, if you want some help you need to give us more info. Do you have a speed that you are able to run Prime95 blend for 20 minutes? I would like to see temps and voltage under load. So you'll need something like HWMonitor free version to monitor these. Run P95 with HWMonitor open and then Take a screen shot after 20 minutes once things warm up. I would also like you to post CPU-z main, SPD and memory tabs. This way we can see what's going on under your hood.

Don't forget mainboard. That tab will show us which revision his board is as well as BIOS version.

Also please fill out your systems specs

I think the OP said somewhere in this string of posts that it was a Rev.4 but this will verify that. Thanks Random

How it hanging bud

 

[Johan45]

@Durvelle27 Good and you ? I've been putting the screws to a new candidate. A 1090T and man I've really been enjoying this one. It seems I may have a really sweey piece here. Was tuning for a Super PI @ 4.0 challenge and have been surprised at how I can push the memory and NB on this baby. Have a look

I'm doing good. Just got into crunching and started back to benching

Crunching as in F@H ? Oh I see it now the world community, what's that all about anyway?

Yes WCD crunching

About to go to school Ill be back and I will post the stuff you asked for

He did say it was Rev. 4, but didn't seem too sure. This way we know for sure as well as what BIOS version he's using.

I know it's a different Rev but it's good to have you watching this one, he'll have the benefit of someone familiar with Giga's bios. They're all foreign to me never had one. I was trying to help a post a while back with an old board and an Athlon. I had a heck of a time figuring out how to do an offset. Turns out it's dynamic voltage or similar ??? It didn't help that the poster himself really didn't know either.

Yeah, that's kind of why I poked my head in on this one. You guys are great with the AMD chips, but I didn't see anyone in this conversation on a Giga 990FXA board. Granted, mine is a Rev. 3 and doesn't clock for crap, but the BIOSes should be similar enough that I can help point him in the right direction.
