I5 3570k @ 5ghz "stable" : Need advice/opinions

[krang]

Hi! I just received my new rig a few days ago, went ahead and built it, then installed the os and all the soft and overclocked it sucessfully to 5ghz.

Here are my components :

The I put in an old ocz vertex 2 ssd in there with a seagate barracuda 3tb HDD I had from my old computer.

Here are my UEFI Bios settings(the ones I changed from the default, all other will be set at default settings) :

Ai overclock tuner : X.M.P.
BCLK Frequency : 100.0 (default but thought it would be relevant to write it here)
Turbo Ratio : Manual
Ratio Synchronizing Control : Enabled
1-Core Ratio limit : 50
Internal Pll Overvoltage : Enabled
Cpu Voltage : Manual
Cpu Manual Voltage : 1.375
Cpu Pll Voltage : 1.8 (Auto usually has it running at 1.816-1.82, so I set it at 1.8 which is a little lower so cooler)
Cpu Spread Spectrum : Disabled
BCLK Recovery : Disabled
In Cpu Advanced power management :
CPU Ratio : 50
Enhanced Intel Speedstep Technology : Disabled
CPU C1E : Disabled (was causing my cpu to throttle even with Speedstep disabled)
CPU C3 Report : Disabled
CPU C6 Report : Disabled
CPU C7 Report : Disabled
In DIGI + Power control:
CPU Load-Line Calibration : Ultra High
Cpu Voltage frequency : Manual
CPU fixed frequency : 350
Cpu Power Phase control : Extreme
Cpu Current Capability : 140%
Cpu Thermal Control : 130
In Advanced Tab:
Internal Adaptive Thermal Monitor : Enabled
Active Processor cores : all
Limit CUPID Maximum : Disabled
Execute disable Bit : Enabled
Intel Virtualization Technology : Disabled
Hardware Prefetcher : Enabled
Adjacent cache line Prefetch : Enabled

So This is my setup. I am running the Watercooling kit on the CPU only but plan to buy a GPU block to add it to the loop later on. I have tried changing the pll voltage down a bit (1.7, 1.75) but my OC gets unstable. I also tried to turn down load line calibration which on High seemed to be doing fine but had a Prime95 crash on blend mode after about 8 hours. As is, I have completed a 100 tests on Very High in IBT with success and then a 12 hour run on Prime95 blend mode without any errors. I really reached my wall at 5ghz cause at 4.9 Ghz I could have a 12 hour prime95 blend run completed without errors on 1.325 vcore, 1.8 pll, high load line calibration and everything else set as with this config with really low temps.

I used the X.M.P. option so I'm running my memory at the recommended settings : 1.5v 1600 mhz 9-9-9-24.

Right now while running Prime95 my temps are at 32 degrees for the minimum heat on my 3rd core(hottest core), and 82 Degrees maximum heat on the same core. Average temp while running prime95 blend is about 67 on the hottest core. While running very cpu intensive games (I'm mostly a gamer and movie/music listener.. I don't use it to compile or any other proffesional needs except the occasional visual studio build compilation) like Arma II : operation Arrowhead my average temps are about 45 degrees on the hottest core (3rd) @ about 45% CPU utilization.

I was wondering if you guys would do any further tweaks to the settings or if you would change anything to get more performance with less heat or anything of the sorts. I would also like to know if this is suitable for a 24/7 setup. I never close my computer... well only if I leave on a trip for several days. I want to be sure this is going to be safe as an everyday OC. I also have a 2nd screen where I have RealTemp and CoreTemp set up to monitor my temperatures so I will always be able to see (thinking of installing rainmeter up again with the meters so I don't have to open the softwares every time I reboot).


Here are some pics :

*Once I completed my 12 hour stress tests I forgot to take a screen shot and closed Prime95, same thing with IBT.. so I started it again now on my 6th hour... will re-post fresh pics of it when it's done and successful.* Also using firefox while running the tests .. watching vids on youtube

So yeah like I said, any tweaks you guys would make? Any changes to my settings would be more optimal? Is this a safe OC for 24/7 oriented towards gaming and media playback? Are these good results ? Please, I'd appreciate any feedback at all :thumb:

Congratulations for the nice OC! 5 GHz is a good OC for Ivy Bridge that tends to heat up exponentially at the high end. Since your OC is stable, leave it alone and enjoy your rig!

wow your in the 5Ghz club good job

Thank you both! Really happy to be part of the club I was expecting 4.6-4.8 when I bought the rig

You have earned bragging rights!

is 1.375v not too high for 3570k everyday overclock?lol if not i will push mine 3570k higher lol ;D

 

[Ubrales]

Most overclockers agree on the 1.375 V limit for the Ivy Bridge processors, even though Intel's limit is something like 1.502 V.

Do not go higher than 1.375V.

thanks) was looking for that info but couldnt find any to rely on )

Huh I thought it really depended on what type of cooling system you were running. I thought that below 1.502 you are in the "safe zone". The only problem is that once you get past about 1.325v the heat rises exponentially, at least thats what I noticed. At 1.325v I was able to get 4.9 ghz stable OC and max temps of like 60-65. Needed to jump a whole 0.05 to get it stable on 5Ghz and my temps went up to 82 Max (usin a stress test). My idle temps are around 23-30 and while playing really cpu intensive games like arma around 45-50.

I can't imagine going any higher than this, except if I maybe had 2 rads and better WC components. I suspect I would get crazy high temps @ 1.4v. Also I think you should try and have your settings configured so that your vcore is stable. When playing around with LLC I noticed that on lower levels my vcore would fluctuate ( go lower, then higher than what I originally set) On Ultra high it stays put on 1.375. having your vcore fluctuate would surely be a major issue when pushing it @ 1.375 24/7, especially if it decided to jump @ 1.385-1.4 ever so often.

I wonder if anyone ever tryed something like this but on radiator placed outside the case

Yes the key is that temps rise exponentially at higher voltages. Another factor is the die within the processor. Some areas of the silicon wafer have less impurities and the location of the die within the wafer has some bearing on how well the processor will function. Some are better than others.

It looks like you got a great CPU. Not all CPUs of the same classification and type perform alike. That is probably from where the 1.375 V came from.

I saw this video some time back. Entertainment.

BTW, this is the principle of multi-stage high pressure pumps that are used in industry on test machines for pressure testing products. Ten-stage (or more) centrifugal pumps for pressure testing products like faucets and water valves..

you already fixed your I5 3570k?
