anyone have this combo and has OC'd ?
smile.gif


please post

i was at 1.320 4.5ghz stable but after few days ive been getting random bsod

( on my other board ive been at 1.320 for weeks without a bsod)

I had that combo at one point until I realized I could get a 3770k for less than what I paid for the 2600k, but when I had the gig. ud3h and 2600k I was overclocking just fine. So yes I have had that combo and I overclocked what is your question exactly

I've got a 2700K with that board; close enough right? I've gotten 5GHz Cinebench and SuperPi stable, and 4.8GHz (1.428V) 24/7 stable along with 2133 on the RAM (1.5V).

You really need to stability test things. You need to run prime95 24 hours on the right settings (just google, I post them every day....).

Most ivies and sandies are terrible overclockers. If your chip can't do [email protected] well that'd just make it a slightly below average chip, but it wouldn't be surprising. Just because you used another board, never stress tested, and never got a bsod, doesnt mean it was stable.

i ran hundreds of IBT LinX and hundreds of hours on p95, theother board was pretty stable.

no need to assume things, i dont see where i posted that i didnt stress test so for you to do that just means you are judging me and jumping to pointless conclusions.

if you guys used any guides to figuring out settings please let me know

you use any guide to break down the settings or any guides that showed voltage range to give an ideas of do's and dont's?

You say you went weeks on the other board without bsod, so it didn't sound like you did any stress testing. You also dont have a portrait or sig rig so it came off that you didn't know what you were doing. And you didnt' say you stress tested anywhere.

Just google the sandy bridge oc club, there's more than one and there's usually a list of people's overclocks and their voltages. There isn't much to do and dont. Enable pll overvoltage, set llc to 2nd highest setting (on ud3h it would be 'Turbo') and then mess with voltage and frequency as necessary.

"And you didnt' say you stress tested anywhere."

but where did i say that i didn't

everyone else says to enable pll overvoltage, you are first to say dont, could you please elaborate?

dont. period. new sentence. Enable pll overvoltage. You should enable pll overvoltage. Sorry that was confusing.

I don't think it really matters to be honest. Ivy bridge, sandy bridge, you just change frequency and vcore and you are done. enable pll overvoltage and llc can be messed with too but really i'm not sure they are necessary. LLC is just so you can use a lower voltage in reality than you would need if you didn't use LLC, but you are talking like .1v difference, and you can only really be sure if it's making a difference by using either a very high quality motherboard or a digital multimeter. Or really, you need a digital multimeter to know for sure, i dont think it matters if you have a high quality board because llc isn't that big anyways (although it can be on low quality boards).

You can't really tell if LLC is working or not without using a multimeter, since software never picks up the right voltage and LLC works in a way that most boards don't read because boards don't report an actual max voltage to you, they report some sort of amalgamation or average of high voltages, and then that gets even further confused by some boards that just don't provide voltage smoothly, or if you have a psu that doesn't provide voltage smoothly.

So everyone just sets their LLC to the 2nd highest, because people with multimeters have reported enough and played around enough to tell us that LLC on the 2nd highest is the most optimal setting for high overclocks. And for like below 4.5, 4.6, you should just set it to low-medium. This seems to hold true with everyone who's tested it but you never know. I tested it a bit myself with a multimeter but I didn't really see a difference with whatever llc i set to.

enable pll overvoltage i think is a matter of increasing your max vcore, in a very, very complicated way, and messes with your sleep settings. You really don't need it. I think sometimes for high overclocks above 47ghz, 48ghz it helps, but it does a 'lot' of damage to the chip.

i seem stable so far at 1.335 , i set it to "Turbo"

sometimes in tests it hits 1.344 on cpu-z

do you think i should just set vcore to 1.340 so it IDLES at 1.344 and never really droops drops drips dips rises or changes? or is it better to set lower vcore and let llc boost a bit

Just set it to turbo. If you got a digital multimeter you can play around to see what truly gives you the least voltage and such, and if you got time. I mean you are talking about like, first, you find what voltage you are 24 hour prime95 stable with no LLC. Then you'd test each level of LLC, and the lowest voltage you can do 24 hour prime95 stable on them. And by voltage, I mean voltage with a multimeter, your real voltage, not what you set in or what the software reports.

Yea, it's not really practical. So do what others have tested out and just keep it at turbo for ambient overclocks over 4.3ghz and try to do the lowest voltage you can. Also whatever voltage you set is going to have a little sway, droop drip and drop. Don't worry about it.

no i wouldnt boost llc. Like it might seem 'oh hey i can do stable on a lower voltage with extreme llc" but in reality you are just giving higher voltage than you were before. LLC in and of itself increases voltage to the chip. Droop is not necessarily a bad thing, you know. The more droop you have, the less voltage you have flowing through the chip, the lower your peak voltage, and the cooler the chip will run. The idea is that with the turbo llc on 4.4ghz+, you are using less voltage than you'd need if you didn't use llc, and this is not something that cpu-z or any software can really tell you accurately.

I mean i hope you realize that the software readings for voltage are never accurate. I had the ud3h for a while and while it's really accurate, it's still off by a bit.

thank you for taking the time to elaborate

yes it seems i hit 1.335 in bios wihch reads 1.332 in cpu-z and i honestly havent seen it droop drip drap drop or do anything during my stress tests
smile.gif


the LLC is on turbo but im wondering how the voltage is so stable

i will re-read what you wrote untill i understand how to apply that to the other mechanics and see if im on the right track :0 thanks again mate

i got it to boost to 1.344 when i had 8 games open and minimized them all, however with all of them running themselves the vcore was at 1.332

at this point regardless of the stress tests, im not sure if i should set vcore to 1.340 turbo llc or 1.332 turbo llc and have it boost to 1.344

with vcore 1.340 it seems it will just stay at 1.344 in windows without changing, still researching, wish more people would give me experiences

when asking , people ask a million questions, but when others ask they forget who helped them and arent willing to share the information
(i read alot, but reading contradicting guides and information only helps so much)

i have no idea what you are going on about. Set llc to turbo, and use voltage offset and fine tune what's stable. I mean you are comparing software voltages and they dont tell you anything on something like LLC. Just see the lowest you can set it in bios, not what the software says.

the voltages i am referring to are voltages set in bios, what is read in CPU-z and what is read in CPU-z under load, which is why i am referring to the different voltages from different vcore under load

yes i know, you are going on about nothing. ive said like 20 times already dont worry about the voltages as read in software and bios. Vcore is close to what your actual voltage is, especially on a high quality board like the ud3h, but if you are going to worry about offset vs manual, and varying levels of LLC, then you really need a multimeter. You can get them for like $30 or something, they are really cheap.

cpu-z also had an issue with voltages on gigabyte boards, it might be fixed but then we got a new bios on gigabyte boards. i never use cpu-z anyways, worthless program anyways. You shouldn't be using cpu-z to monitor your hardware, use hwinfo. There's plenty of other programs too but hwinfo is pretty awesome and you only need that 1 program instead of 5 different ones.

whatever the max voltage you hit on vcore, the max value, that's what you say is your vcore. All voltages and settings will fluctuate a bit, it's just electrodynamics and it's how electronics work, it' practically impossible to get rid of all fluctuation. Fluctuation is, or can be, a good thing anyways. You can search for more in-depth explanations on vdroop and offset and such.

Just set llc to turbo, use manual voltage to figure out what's the max frequency you are gonna run and what you are 24 hour prime95 stable at, and then switch to offset voltage and set your offset so that the vcore matches what you had stable on manual voltage and tweak as necessary for stability and 24 hour test again.

ok i understoof everything but the offset, could you please hold my hand and explain what setting offset is? which option would that be , it feels like im at the final stages of "stabilizing" on my board and that would be the last

ty very much for taking the time to post

downloaded hw info x64 and coretemp

going to try to figure out the offset, but i still have no idea what option i will change in bios even after reading the guide

dont be a tease
frown.gif
spill the beans, dont let me learn from trial and error by setting the wrong option to an insane voltage!

you got me this far! dont just quit =(

Any recommendations on what I need to set/tweak to get my i7-2600K at 4.0 GHZ overclock? Im on air, and really don't need to push it past that.
