How do you get around the 2600K idle bug? - Page 4

post #31 of 117
Thread Starter 
I think I am just going to back off to 4.1ghz at 1.225 volts

I don't even crack 50C with Linpack under that

I did get it fully stable by turning on SOME LLC and setting it to 1.320 volts, it never dipped below 1.310 volts, but I don't feel right riding that close to the 1.350 top end zone

Funny thing, I think this heatsink needs to reach a threshold of heat before it stops increasing, 100% load I saw no difference between 1.290 and 1.320 volts or setting PLL up or down from default settings for heat output ever since I re-applied the heatsink

In fact, since doing the re-apply, and doing 8-10 hours of Linpackers, my idle temps are down 6C, some cores actually reach 22C at times even

That vcore is fine. But try doing what I said and raise the PLL voltage slightly and drop the LLC or vcore a tad and see if that helps. I Just found on my "degraded" 2600k that used to do 4.5 ghz at 1.236v for hours, but now BSOD 124's within 5-10 minutes of prime, EVERY TIME, raising the CPU PLL voltage to 1.86v allows it to pass over an hour of prime blend before the 124 error hits. (of course raising the vcore helps too). It's worth giving it a try.

I'm currently trying 1.248v load at 4.5 ghz with 1.86v PLL and so far its made it through 5 hours. Without the PLL, it would BSOD in 45 minutes to 2 hours here. I'm pretty sure that if it was a 101 error instead, PLL increase wouldn't help one bit.

I only caught this because on my first 2600k which degraded a lot from some extreme vcore (1.5-1.58v), prime gives me 101 error EVERY time if the vcore isn't high enough. But this cpu gives 0x124 instead, which means something else is failing, instead of the cpu cores just freezing.

Not saying it will help at idle, but pretty sure tweaking cpu pll, VCCSA or VTT can cause different results if you get 0x124 at full load.

You are probably right, but I think I am just going to go with what is working, plus I want this PC to last 4-5 years from now (Baring Fan/HD replacements) since the reason I bought the parts I have just cause I want it to last years and years, sick of upgrading every half a year to a year, the 2600K outmuscles everything by a longshot for anything I need

I'm amazed at how much more snappier windows is, my Phenom II 1090t wasn't even half this quick for windows functions, even the boot time is half what it used to be

When I had faulty RAM it would hang/bsod at idle, but pass any stress tests completely fine (including memtest, before the stick completely failed)

You also have a large amount of memory, it might be putting a lot of stress on the CPU to keep it all running. I would recommend testing the sticks individually for a few hours (overnight if possible) to find out if any of them are faulty.

My stock voltage overclocking attempts were the same thing, at 4.3ghz it did 1.225 volts for EIGHT hours of Linpack

Could you do me a favour and run this, 20 runs with maximum and please post a screen shot with cpu-z and realtemp running. It shouldn't take really take no longer than 10mins.

Thanks

First thing I did was do default clocks for the CPU and run memtest for 4 hours when I built the system, just to make sure everything worked fine at stock

Then I did Linpack for 2 hours at stock to test, then idled for almost 24 hours, since then I have been overclocking

EDIT: I am also agreeing with you, I am willing to bet its cause I have 4 sticks of ram why I need so much CPU voltage for stability, my Phenom 2 1090t needed the same coaxing in order to run with 4x2Gig sticks
post #37 of 117
If it's too much trouble to run 20 then you could atleast do 10 runs on maximum with intel burn test and post a screenie with real temp and cpu-z.

thanks

Why do you need me to run intel burn test again?
post #39 of 117
Because you claim that your cpu is stable and im just asking for a little proof. Also would like to see your temps. Could you do 20runs on maximum with the one i just posted. By the way you need special pack 1 installed for it to run properly.

EDIT: specifically 4.5ghz with 1.260v. Please post a screenie.

So Im now up and the PC did not BSOD while IDLE, so C3/C6 may have dropped the voltages down waaay to low!

@Falk,

I've been using PLL at 1.520~1.600 ( just randomly changing them ) and I do get a 124 BSOD on blend with my 4.5Ghz settings (I've stabilized my 4.8Ghz with 1.452v) VTT is at 1.120v mostly and VccSA on the Gigabyte is 0.920v stock.

Im backing down to 4.5Ghz since it requires far less voltages, Rignt now I have it at DVID with a -0.010v offset LLC = OFF, with the 4.8 I had to enable LLC and DVID at +0.115 to maintain 1.452v or it will bsod 101 on me.

From what you've posted PLL might be able to help me on the load 124 errors, how about VTT/VccSA what should I look for in order to know when to change these.
