post #3901 of 10702
always interesting to me how much variance is in these chips for overclocking. My first 2500k wouldn't even post at 4.6 no matter what vcore I put on it. Exchanged it for a new one and it's like night and day.

added, however as other have a suggested a reseat might be a good idea, those temps look awfully high for that overclock even with the 212+, have a look at all the other 212+ submissions and you'll see what I mean.

BIOS TEMPLATES

I have created a sheet for BIOS templates, it could be a reference point to other's including oneself and a quick 'copy and paste' whenever required in other threads/posts etc.

Those that have posted their stable systems please spare a few minutes of your time to do this. One more thing, these are the ones im after:
  • Main BIOS page (The advanced settings main page)

  • Full AI tweaker Page including DRAM Timing control

  • CPU Configuration Page

Come one Guys n Gals I want to see more BIOS templates up there!!!!

So I've been fumbling with my computer to see what more I can push it too. This is what I have going so far.

5Ghz @+0.140 vcore offset, basically under load the VCore fluctuates between 1.456 - 1.472 but prefers 1.464 the most.

I ran 20 minutes of 1344 and 1792 FFT's and they succeeded (I know they aren't super reliable for stability but it gives me a baseline). Also got a max temp of 78c.

I do want to do a 12 Hour P95, but I'm just curious if it does pass a 12 Hour test, would be 1.472 Vcore and around ~80c temp be safe for a 24/7 OC?

pretty impressive if I say so myself especially the temps!


****Max Safe Voltage and Temps****


Before I go into this, I just want to say that this is my OWN opinion and take it as you will.

No one is absolutely certain of what the safe vcore is for the sandybridge chips. What I can tell you is that many say the max safe vcore for these chips are 1.3 region, however, intel states that the max 'VID' is 1.52 and many say that around 1.4 if your on air and 1.45 should be the max if your running water cooling. Personally I will not go above 1.5v for 24/7 with these chip but that is totally upto you. The main thing to understand is that 'YOU' have to come up with the conclusion of what the max is. That way no one is blamed if the chip degrades (none reported so far, even with so called 'high 1.4+ vcore')

Those that have killed or degraded their cpu's have done so through either by their own fault, running sucide runs with crazy voltages and by not having substantial cooling for their overclocks and voltage or for reasons like their mobo or PSU causing shorting and also BIOS bugs.

Please remember that not all chips are the same, some can do high overclocks with low voltage some cannot as you can see in this this thread and many others.

Regarding temps, CPU throttles at 95c, some say keeping it below 85c is good, some say keeping it below 80 is better, other's say below 75c is really good and there are quite a few that say 70c should be the max. Which ever one your comfortable with and if you have substantial cooling, YOU DECIDE YOUR MAX, just remember it throttles at 95c. If for example you hit 85c in stress testing then in everday usage it shouldn't be higher than 75c which I think is fine, I personally like to keep mine below 70c

This will conclude any max safe voltage discussions, if you have a question's about it create another thread or PM me.


Take it as you will and YOU decide, I say it's fine. I've been running mine for over 7/8 months and all is well, how long it may last I cannot say and I don't think anyone will be able to give you a time frame. For me im not that worried because I may even go to SB-E or even IVY, but more than likely I will keep this rig as it is for as long as it goes.


Hope that helps

You can check my temps in the spreadsheet for what to expect. ~24C ambient @ Balanced setting btw
Yeah I am very conscious of noise. So you're saying that if I am worried about noise, I would want to replace the stock fans? So if were to replace them, which fans has the best noise per cfm ratio? I heard Gentle Typhoons but they are so pricey and hard as heck to find. Also, I am not entirely set on the H100, because I know Noctua Nh- D14 does a good job and so does the Silverarrow. I just want the best cooling for the least amount of noise. I' sure that everyone wants this even though there are those who care less about noise. I want it as a quiet as possible with hi static pressure for the rad push fans, and awesome noise to cfm ratio as well.

The thing is, with the air cooler's and please correct me if im wrong, but im sure most ramp up the speed for stress testing and just lower it for everything else which in turn allows for a more silent rig and having a decent overclock with decent enough temps. For example when I ran prime for my 12hour blend, all 6 of my fans were at 20%, barely audible, and the temps peaked at exactly 70c and no higher, however, if I did say increase the fans to 50 or even 100% I'm sure I would have knocked off a few degress.

Try not to base the load temps of stress testing into everday usage or general gaming. That is what some do after they run IBT or LinX with AVX which I hate completely.

I think I will most likely do a 12 hour P95 run tonight and see what it yeilds. I just get annoyed when I see people with air cooling getting 5Ghz and I feel like I should push mine to 5Ghz with a pretty good water setup. But if it fails and needs more VCore I will most likely go back to 4.8Ghz just because I am not comfortable with anymore VCore than I already have.

'Don't knock it till you try it' therefore, thats a very good decision, like always, let us know if you need any help

Heh, I am certainly in touch with "chip envy", I get that every time I think about munaim's chip, lol.

LOL i got lucky, my first chip and worked out quite well for me, boots at multi 57 lol, the mobo however was a doa when I first built my rig, wow I was sooo peed off.
