Help: 2600k Throttling @ 87c in Prime 95

post #1 of 8
Thread Starter 
Hey guys, I'm having trouble overclocking my 2600k. Whenever I hit 87c my multiplier dips down. Here's my hardware:

I7 2600k, Stock Heatsink
Asus p8z68-v Pro
Corsair ZX 1000W
8 GB Corsair Vengeance
Asus 580 GTX DirectCUII

Here's my settings:

x45 multiplier
1.370 v-core. 1.360 and below would 124 BSOD.
AI Overclock Tuner - Manual
BCLK - 100
Turbo ratio- All Cores
EPU Power Saving Disabled
VRM Freq - Manual, 350
CPU Current Capacity - 140%
Load-line calibration - Extreme

C1, C3, C6 Disabled
Speedstep disabled

Now, I know I should upgrade my heatsink ASAP and I went ahead and ordered a silver arrow. However I'm still troubled by the fact that my processor is throttling even when I have it set not to.

Any help would be great, thanks!

Hmm weird I thought the thermal limit was the same as tjmax at 97c. Perhaps you have temp probes out by 10c that would at least make sense.

Try lots of different progs to see temp especially the one that came with your mobo.


Addendum:
I never run mine above 72c anyhoo.

To be honest, 87c is very high, I try and keep mine below 80C and closer to 70C.

Also what are you using to read temps ? Get Realtemp 3.67

Thanks for the tips boys. Turns out Asus AI Suite II reports temps 10c lower than what realtemp 3.67 did.

Looks like I'll be holding off the OC until the heatsink comes in.

That would be a good idea. Cpu usually throttles around 95c and thermal shutdown is at 97/98c I believe, however using a an aftermarket cooler would definitely yeild better results that that.

Also refrain from using asus suite for any type of temp reading, it'll mostly pop up with an error one day saying your mobo temps are above 100c lol

Also here is an updated version realtemp: http://majorgeeks.com/Real_Temp_d6098.html

Hope that helps

Definitely hold off. You're gonna love that silver arrow. Nice choice there.

Glad my reply helped. You are really going to love that Silver Arrow for sure. Not that i'm trying to ruin your fun but that cooler will also allow you to go a little silly on your overclock voltage and as such you should be aware that keeping that 2600k cool will not stop its sensitivity to voltage and resulting degradation. The 2600K I had before this burned out after 3 weeks at 4.8Ghz @ 1.44v hence the one I have now I decided to simply see what max overclock was on stock volts. Not only does this give me ultra silence as my fans all run at minimum and the cpu stays well within 70c thermals. I know you probably want to shoot for 5Ghz but just be careful. What I noticed was with LLC enabled even on medium when the chip was degrading it would make little correctional jumps up in voltage to maintain stability. As time progressed the jumps became more frequent eventually leading to BSOD. Even at 1.35v I noticed these jumps so id say these chips are uber sensitive to volts. Only at 1.295v and below did I notice totally stable volts without any weird jumps. Now alot of people use constant volts, they feel that the constant volts protect them from the spikes of LLC which is true to an extent but if you are still over voltage threshold ul be incurring damage. Also what alot of people miss is the low end damage. After cooking my 2600k at 1.44v I noticed that it would crash at idle as the voltage needed for idling had been burned to a higher requirement. Again people using constant volts and clockspeed would not notice this until damage became noticable at top end like my did after 3 weeks and would simply BSOD setting the volts to 1.44v even before id changed multi. For me having the lowest possible stable idle wattage/clockspeed is important so burning out the lower end for short term 400-600Mhz increases is a no go.

Yeah defiantly way to hot. And i like to keep various programs open logging the temps to make sure i get an accurate temp. Coretemp, HW monitor, Real temp. Also make sure to run intel burn test on maximum because that makes the temps heat up like crazy! And yeah i like to keep mine below 70 C. 65C in prime 95. Intel burn test hitting maybe 75 C. Keep in mind this is with the ambient room temp up to 90 F. Now its 80 F Ambient and im barely hitting 68C with intel burn test. In winter this OC will be very stable. Because it runs thru the hell of summer. And make sure you get rid of that bad heatsink Also asus suite is really bad because it randomly pops up with wierd warnings like......*Voltage at 1.92 Vcore or PC TEMP -100C WARNING! lol its very glitchy and i don't even have it installed anymore.
