I was not wrong. Stock voltage is ALWAYS a max of 1.25 plain and simple. I never cared what he was running. If he is running auto cool, if its STOCK cool don't care. He should be running stock though as auto uses to much vcore.

He more then likely left it on auto, however A LOT of people run 1.25 vcore for 4.0ghz or higher as that is considered the "stock" voltage. Go to google and type in "2500k stock voltage" and you will here a bunch of responses saying 1.25 max.

edit

The point being is that if you select AUTO voltage and put a 40x multiplier in, it runs TO MUCH voltage.

If you select 1.25vcore and hit 40x multiplier your at 1.25vcore.

Do you understand yet?!?!

I directly asked him if he left it on auto and YOU are the one that jumped in here and started all of this nonsense for nothing.

 

[fastamdman]

so does that mean you left voltage on auto? if you did then your system is using way too much. and no way would I run 4.2 on the stock cooler. at that speed on the stock cooler, my temps hit 80 very quickly in IBT and would have kept going if I did not stop the test.

Going by that quote I saw a ? and I was just giving my 2 cents that he could have had it at "stock" which is a max of 1.25volts, but if he is running auto like you said then we both agree he was using to much voltage

<3 no bad feelings. Was just trying to point out that a lot of people use the word stock to refer to 1.25 volts 🙂

Back to the topic, I've binned a bunch of sandy bridge (2500K - 2700K) on a handful of different boards so I'll give you my experience.

All Sandy Bridge processors I've tested run stable at 42x on (1.225 - 1.25v).
Most SB will run 43x on (1.225 - 1.25v).
44x requires in most chips a slight bump (1.285v - 1.290v) but never 1.3v in the ones I've tested.

I don't trust auto OC, I don't want my base clocks changed. I don't trust auto voltage at higher multipliers, you'll see voltages go way over 1.5v. In any case, it only takes a bit of testing to figure out the voltage for your proc. However, worrying about your voltage at 1.300v is really unfounded. I'd care more about keeping it under 1.35v or 1.5v depending on your goals. The point of overclocking is increasing IO? Higher clocks need more voltage to switch those gates faster. There are worse things than a few millivolts, like crashes and silent data corruption.

Coolers:

I think someone said 4.4 might be ok on the stock cooler. No way. I've not seen a Sandy Bridge go 44x on stock cooler without getting into 85C-90C range. They are horrible. Try it and see. There is a reason the Intel SB coolers have such a bad reputation.

It depends on your chip AND board, but the best chips I have (2500K / 50x @ 1.430v Prime stable) and (2600K / 50x @ 1.435v Prime stable) actually run these speeds on air with a $34 Hyper 212+ EVO. I had lesser chips that got hot 48x and did better on an H100 cooler. I'm still looking for the best in the $40 range, so far the 212s are the best at their price level. Overclocking a chip on the stock cooler, when there is such a good cooler avaialble for $25 is, to me, like running your car with the radiator half empty.

 

[fastamdman]

I agree with mrjoltcola 100&#37;, HOWEVER stock coolers do depend drastically on ambient temps. When you are blowing 0 degree F air into a case, you can use a stock cooler and higher voltage 🙂 But for normal use, ya get a cheap hyper 212 and save yourself the thermal shutdown / throttling lol.

Oh and for the car analogy, my 2 cents <3, its more like running a race car on 89 octane and getting 200whp instead of running it on 91/93/methanol/e85 and getting 350whp 🙂

My hyper 212 as we speak is folding at 4900mhz at 1.48 vcore. Stability is in the eye of the beholder. P95 misses some things that LinX/IBT will catch, and does it much quicker. There is a reason LinX and IBT temps are higher, the gflops are higher, it stresses the system out harder. Mathmatically speaking your PC is working MUCH harder in linx/ibt then p95.

I went by p95 for years and I am 100% anal. I did 15hrs linx testing and 2 days of p95 on my 4.5ghz run. Right now though, I am in a folding mood so 4.9ghz here we are =D

 

[daninfamous]

I am running a 212 plus =)

 

[Clinkster]

4 Ghz should be easily obtainable on stock settings and cooler. If you decide to go any higher, I'd recommend getting a better cooler (Intel is super poopy).

 

[fastamdman]

Absolutely, any time you are using STOCK vcore aka a max of 1.25 *lol*, then the stock cooler is just fine. But when exceeding STOCK vcore *read as a max of 1.25 lol*, then a better cooler is needed.

Granted it REALLY depends on ambient temps. I keep it really cold in my place so I have more headroom. Hell I ran 1.6volts through a chip near the window on air 🙂

 

[toyota]

1.25 is not magic as the higher clocks can still get the cpu VERY hot. you can usually run a 2500k at up to 4.4 with just 1.25 but in way is that what I would recommend with stock cooler. it will still go over 80 C pretty quickly even at just 4.2 an 1.25. at 4.4 and 1.25 it would probably hit 90 C pretty quickly in IBT.

 

[fastamdman]

Your english suddenly got worse lol. Anyway once again the intel stock cooler isn't the best but it strictly depends on vcore and ambient temps and what your processor can do. Also MOST can NOT do 4.4 at 1.25 stable. Hell my 4.5ghz needs 1.39vcore for 15hrs LinX stability. I am running at 4900mhz right now but thats beside the point.

The majority of chips with a stock cooler can do stock volts aka 1.25 and 4ghz without to much stress but there are a lot of factors. Just watch temps and that is that.

1.25 is not a magic number but its the max number that intel uses so a lot of people like staying with that. Also staying at 1.25 and under ensures there will be little to no degradation. The higher the vcore is, the less life the chip has.

 

[toyota]

the POINT is you are giving out bad advice. you make it sound like you can run any speed you want on the stock cooler as long as you do not exceed 1.25. that is nonsense.

 

[fastamdman]

IM GIVING OUT BAD ADVICE!?!?

You are the idiot saying people can do 4.4ghz on 1.25 and I am telling you that the MAJORITY CAN NOT. Until you have BINNED a ton of chips, you shouldn't be giving information like this out when you are just talking out of..well you know what.

Seriously I JUST said that most can do 4.0ghz on 1.25 but that the majority CAN NOT do what you are saying.

1.25 is just a number for stock voltage, I and a lot of others run A LOT more then that. Quit trying to make me out to be the bad guy, you are an idiot talking out of your ...

You are an idiot for saying this, the majority of chips will not do 4.4 at 1.25, plain and simple. I hate you by the way, its official.

Oh AND just to be clear you CAN run 1.25 on a stock cooler at ANY speed that you want as long as temps are within range.

I RAN 1.6 volts through a stock cooler, it depends on temps 100&#37;, jesus christ go away.

so now 1.6 is safe onstcok cooler? for what? idling? lol, and you call me the idiot?

grow up. all you have done in this thread is make a fool of yourself. you say one thing and then backpedal a bit. you then try and take one part of what I say and call me an idiot while missing the whole point.


AGAIN staying at 1.25 does not mean you can safely run any speed you want with a 2500k using the stock cooler.

and now 1.6 is safe on stock cooler? for what? idling? and you call me the idiot?

 

[fastamdman]

Your temps at 1.25 with stock speeds are similar to 1.25 at any other speed. Vcore plays a HUGE part into temps not direct speed. Whether or not you are steady is another thing. I have given NO bad advice, nor have I back peddled once, quote me on it if I have.

You are saying people can do things that majority can not, I am not.

ALL I HAVE SAID IS THAT STOCK COOLERS DEPEND ON TEMPS, LOWER VCORES LIKE 1.25 HELP, AND THE MAJORITY CAN DO 1.25 AT 4.0GHZ, THATS IT

the more you type the dumber you look. my temps were WAY higher at 4.2 even just using 1.23 than at 3.4 using the same voltage.

 

[fastamdman]

Must I go take another screenshot, granted I am on a hyper 212 currently but vcore plays a HUGE part into temps. The lower the vcore for the desired speed, the better, as long as the system is "your" version of stable.

Look I am done arguing with a monkey, I have already gotten pm's about you and people have already said they agree with me. I gave solid advice and until you can quote otherwise, this is over.

Also "Way higher" is not very accurate. Look at stock temps for intel coolers at stock voltages at max 1.25volts, and then look at them at 4ghz at 1.25 volts 🙂

As long as temps are within reason, it doesn't matter! ITS ALL ABOUT THE LOWEST VCORE AND LOWEST TEMP FOR THE HIGHEST O/C

Every chip is different guys, not all chips can do the same thing.

 

[toyota]

and as you can see I am able to post screenshots too. I already showed that your earlier comments were nonsesne and I can do it again here. you also keep claiming that you have said nothing wrong when you have. you claimed that 1.25 was stock voltage and that was wrong. another example is when you acted like 3.7 on a single core would use more voltage than 3.4 on all 4 cores.

now I tested my cpu at various speeds on the stock cooler before deciding to get an aftermarket cooler. I know damn well that 4.2 was too hot for me and ran WAY hotter than 3.4 even at the same voltage which was below your magical 1.25. it hit 80 C pretty quickly and no way was I going to let it run any hotter than that so I stopped the test before it got hotter. at stock 3.4, it was only in the low 60s though at the same voltage so do not keep spouting your BS.

 

[daninfamous]

I dont even have a stock cooler so that argument is irrevelant to this post.

 

[fastamdman]

Toyota - Just stop arguing. You posted a pic, I posted a pic and the MAX voltage as I said was 1.25 volts, k thx. Every chip is different and ambient temps differ from person to person. Just because your chip ran hot doesn't mean they all do. I never said chips could do 4.2 and 4.4 on the stock cooler with high ambient temps like you did. I said that the MAJORITY could do 4.0 at 1.25 on a stock cooler. That means the MAJORITY, not all of them.

Every chip is different, my chip doesn't change 20 degrees from a few hunded mhz at the same voltage like your chip supposedly does.

Either way man, lets stop arguing. In the end we both agree. Don't run chips to hot, don't run to much vcore, use a good cooler, check temps and stability. Plain and simple.

 

[toyota]

well maybe we can get back on topic now. what clocks and voltage did you finally settle on for now?

 

[fastamdman]

im assuming a 4ghz clock should be cake, what kind of vcore you guys think would be about right for 4ghz

waiting on ups to drop off the ram so i can fire it up, dunno why everything except the ram came yesterday.

Getting back on topic, you should be able to get there with 1.25vcore but if that is not stable then raise it slightly until you are. Test with LinX with avx / sp1 and make sure your temps are within reason. You can hit 4.5ghz no problem with your chip, it will just take more voltage. You can run anything up to 1.4 - 1.45 24/7 without issue.

Also make sure your ram is 1.5voltage, the IMC doesn't really like ram that is rated higher than that.

your words are right there for every one to see. you made several inaccurate comments and generalizations. you keep trying to twist my words and take them out of context though which is funny. in fact you keep changing up your own comments and adding qualifiers AFTER I say something to you.

lets cover the stuff you were wrong about:

"Stock never changes, stock will always be 1.25 no matter what, auto changes with speeds."

"INTEL SPECIFIED THAT STOCK VOLTAGE IS 1.25, what don't you understand about that? When you run STOCK speeds, what voltage do you get, hmm 1.25 max, because thats the STOCK VOLTAGE."

"EVERY 2500k CPU HAS THE SAME EXACT STOCK VOLTAGE. EVERY 2500K IN THE WORLD USES THE SAME MAGICAL NUMBER CALLED STOCK WHICH IS 1.25, jesus."

1.25 is not stock voltage for a 2500k like you claimed.



"Auto voltage vcore at 3700mhz can peak at 1.25 vcore"

"That was at 3400mhz...not 3700mhz, cough Try again bud. I also said MAX so you gotta account for your board leaking voltage, but still you will see 1.25 at 3700mhz"

running 3.7 on the single core at stock settings does not use more voltage than all 4 cores at 3.4 like you claimed. it uses LESS.



"any time you are using STOCK vcore aka a max of 1.25 *lol*, then the stock cooler is just fine"

1.25 does not mean you can run run whatever clocks you want on the stock cooler like you claimed.



"Your temps at 1.25 with stock speeds are similar to 1.25 at any other speed."

and using 1.25 does not mean you will have similar temps regardless of clocks while using stock cooler like you claimed.

 

[fastamdman]

Oh look you are still quoting me, yay!
1st up, 1.25 is the MAX stock voltage, show me where it goes higher on stock settings and then you can say that is not the stock vcore bud.

I never claimed 3.7 DID use more voltage I said it CAN use 1.25max. I can run linx and not use 1.25, but run p95 and use more or run aida64 and use more etc. THE MAX voltage s 1.25, it's not always 1.25, but the MAX will be 1.25. You really don't understand the words CAN, MAX, MAY, MIGHT, etc. EVERY chip is different. Clearly you haven't had may chips.

You CAN run 1.25Vcore on the stock cooler but temps vary. Show me where a stock cooler that has proper thermal paste on it or decent ambient temps can't run 1.25vcore. EVERY chip and EVERY machine varies but the max clock that is going to be stable on 1.25vcore will not be running at 90c. Especially considering 99.99&#37; of the time systems aren't running LinX or IBT. For example FAH runs MUCH cooler, P95 runs MUCH cooler.

Using 1.25vcore is the BEST chance for overclocking the stock cooler. Using any more and you are going to run into issues IF ambient temps are to high. What do you want people to run auto and 4.5 on a stock cooler?

If your going to overclock on the stock cooler your BEST chances are to use LOW vcores. I don't know why you are fighting me on that. You can't run high vcores on a stock cooler without really low ambient temps. Plain and simple, temps WILL be lower at 1.25vcore then higher vcore, PERIOD.

Everything you just quoted is right btw. Temps don't increase 20 degrees from a few hundred mhz even on the worst chips. Its the VCORE that makes the biggest difference not the multi. Besides you can't get the multi stable without the vcore so what is your point.

 

[daninfamous]

still at work, were deploying windows 7 to 60 machines tonight and not all the aps were dropping are testing, lots of OT =)

 

[fastamdman]

Good money is good that a boy. Let us know how the overclocking goes later!
