i7 2600k overclock causing lag in DCS?!

[D4n]

Ok I ordered the this one http://www.alpenfoehn.de/en/cpu-cooler/bennevis

and rlly hope I can reach 4.4 GHz (stock clk +1 GHz I realized xD ) without going above 70 °C and without too much fan noise... :)

[D4n]

Btw. the DCS was NOT lagging anymore when doing the OC in the BIOS, so it was too low voltage for CPU and DCS didn't like it... :P

[Pilotasso]

low voltage doesn't cause pauses, it causes bluescreens.

If the cpu becomes unstable, it can cause freezes w/o bsod, but it would have to be right on the edge, and you'd still get lots of crashes, yeah.

Ok, installed the cooler today (removed instel stock cooler, removed old thermal paste from CPU, applied new thermal paste, removed paper from cooler backplate and from cooler (so the glue on the backplate keeps on the motherboard), and installed the cooler) now getting 67°C max. under medium/heavy load (CPU instense game). I set the BIOS already from "silent" cpu cooler-fan mode to "standard", should I try "turbo" mode? I think the my new cooler has a very silent fan, so I wouldn't hear it too loud on turbo, and maybe I can get to 4.5 GHz ? (Now set to max. 4.0 GHz) What do you say?

Get watercooling :)

More exensive (I got this cooler for 25 € ! Water coolers cost 50-60 € in Germany...) and if pump fails, well... trouble...

Exactly.

[Hadwell]

if the pump fails, no trouble, there's still enough cooling for you to use your machine long enough to order a new cooler or pump.

 

and cpus shut down on their own if they overheat now, it's not like back in 1998...

1998 ? I was 6 years old back then, getting teached on using Win 95 by a friend... xD

you're talking about cheap (or used) AIO solution... watercooling guys are talking about is something more like 50-60 € for used decent waterblock for cpu... and another 250€ for tubes, pump, rad and fittings. thats the way to go if want to OC and have your cpu cool and quiet :P

 

btw, got my 2600k running at 5GHz, not hitting 70C under load with just 2 fans at 2/3 of the speed :smartass:

[BitMaster]

You can run the 2600k non-overclocked for quite some time without a pump if your cooling block has enough passive cooling material...copper for example.

 

Treat that 2600k right.. I manged to squeeze mine up to 5.245MHz tonight by accident ..and it worked for half a round in the Ka on 104th and then Win10 told me it needs to catch some data and reboot, not even froze with BSOD LoL.

 

The Voltages are a tricky thing, I cannot set my voltages in Bios as low as from GUI.

 

and hell yeah...it booted Win10 with 5.14x and 5.24x MHz just fine from oc in Bios, just the Volatges were astronomical...1.5V for 5.2x not even wanna try prime95 for 3 seconds ;)

 

Never tried the BusClk before, but it worked flawless till 103.1x50 ;)

CPU-Z tells me that my P8P67 pumps 1.330 V into the CPU... :P

Getting 4.4 GHz with max 70°C on air cooling!! (Do u think the thermal paste quality matters? Cause it is some no-name thermal paste that was included with the cooler that I applied to the CPU... was very little paste, but I heard somewhere the less the better)

Cooling paste does matter a lot if you want to push it to its limits.

 

The one I use is a cermic compound that needs a few days and cold/hot cycles to fully settle and give max cooling performance.

 

If I was you, I'd get my a AIO watercooling like Corsair if you want it quick or invest in a modular system and have the door open for later additions like watercooled GPU and/or mainboard.

Also you can choose any kind and size of radiotor(s) and pump(s).

I can highly recommend this thread that goes ito detail and specific versions of the SandyBridge CPU as they differ quite a lot with changes in version. I was lucky to get the best of the best 2600k ever made, D2-7 Stepping, runs up to 5.250GHz, I am running it on 5.0 in DCS now for the first weeks after using it at 4.8 for a year. It now fires flawlessly even higher ( fully burned in ) ;)

 

 

Check your version and if you are lucky you have a late 2011 version, D2-7 as well with lots of potential.

 

I have a relative high voltage jump to stay stable between 4.8 that only needs 1.35V for the most brutal work ( prime95 + kombustor draws over 630w when both chips are overclocked ).

 

For anything higher than 4.8x I need 1.40 Volts and considerably higher temps when stress testing. In DCS the temp "only" jumos from 44-49°C to 49-56°C, which is still very acceptable.

 

I would just NOT run a stresstest for 2h not because it would fail, because it would do it and thus stress the hardware to an extend that makes me feel bad, I dont wanna ruin it !

 

 

It also WON'T for sone reason go beyond 4.8 from within Win10, I have to boot the 4.8x+ speed, say 5.0, and then go to Asus GUI and set back Voltage from 1.49V to 1.40V or Asus pop-up warns you every minute your Vcore is exceeding 1.56xxVolts...up to over 1.6xVolts...ehhhhh :(

 

I tried in small steps and it seems 1.40V is the sweet spot were it still doesnt wanna reboot and collect DAta ( no BSOD or freeze usually, very very seldom, it pops up a Win10 error msg and then reboots...makes me think its kinda windows thing too being too picky ) but stays cool enuff to use it.

 

Also, if the outside temp is a brutal 35°C or above 100°F you DON'T do this "at the edge" thing as your water is like 10-15°C waremer to begin with...and in the end we all cool with air, even wc-systems. Unless you go LN air temp is the base line you begin with.

 

 

I have played with other CPU options as well but none seems to change the behaviour of the CPU dramatically, either way. I have Speedstep disabled for a few days...no change...other than more heat and min base clock of 3.4 instead of 1.6GHz.

 

What is maybe good to know is, that the OC functions in your Bios should NOT be at the far edfe setting to achieve the highest speeds, like LLC and CPU Max Profile ( whatever those functions are labeled ).

When I went to my 5.25GHz journey I read another article specifically for the 2600k d2-7 towards 5+ GHz...and they say take those settings back to modest, the first 1/3 of the range given....and it still worked...with less stress on the HW as I had most of them on MAX or 1 notch below.

Must be said, the CPU works to 5.25 on all those settings, just the temps and stress might be lower oif you settle with lesser settings and try that. If it works, less is always better in OC, few excemptions.

 

I would not run prime95 on 5.25GHz...my cooling would not be sufficient !!! 100% garanty.

I also would not play on 5.25GHz, NO WAY...but it tells me that 5.0GHz is 250 away from the current limit and I can "safely" use it at 5.0GHz, even if the CPU is stressed out in VMware or iTunes, Handbreak or whatever utilizes many or all cores you have until the job is done.

For the past 2 weeks the machine runs almost 24/7 at 5.0 with gaming/work/video and multiple users flawlessly ( my son and me game on it).

 

Best thing ever, I got that CPU/MoBo as a gift for free, it was replaced and put to junk HAHA !!!!

 

The 2600-k / SandyBridge are still awesome CPU's, with 5.0 I dont even fear a comparison vs. a Devil's Canyon CPU in stock or modest OC. Only A Devil's Canyon at same frequecies would amke we wanna change now...if it comes dirt cheap ;)

I would like to know what this one guy with a 4.9GHz 4790k and a good GPU can shuffle in 2.x NTTR. Must be mind blowing speed !!! :)

BTW....I can read 4 different Volatges applied in 4 diff apps same time....

 

What I refer to is the Voltage shown in Asus Gui for OC, not Asus Sensors tab, not CPU-Z, not HW-Mon....they all differ a bit in Voltages shown.
