Hi guys, i overclocked my 2500K to 4.6Ghz but i am facing some problem when running LinX test

RAM Frequency:: 2133Mhz
VCORE:: 1.4
DRAM:: 1.65
others voltages are set to auto

Prime95 Max Temps
In-place FFTs :: 78C(MAX)
Blend Test:: 77-78C(MAX)

but when i run LinX test
Problem Size: 30600
Memory : 7168
Run: 20 Times

i get blue screen even before the first loop, temps hit to 82C  , i am abit confused weather my OC was a success or failure, need some feedback people, thx
btw i didt encounter any blue screen before this, and is it better to use XMP profile or manual? im current using manual settings for my RAMs.
I have been keeping this settings for 2 weeks and had no problem before. Today while playing FIFA i faced some lagging issues.
The game does not lag even at stock setting, so i was a little astonished and ran LinX and blue screen appeared.

What's the code of the BSOD?
I suspect it's related to insufficient vCore. Try upping your vCore slightly.
Good luck

the code is 0x101 & 0x124, i increased to 1.43V and runned intel burn test
Set:20
Stress Level: High (2048MB)
All Thread.
temps are rocketing to 86c on my CORE 2 bro. How bout PLL voltage its auto currently.

0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT... have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

hi,i want to ask my i7 2600k with asus p8p67 pro,i try overclocking to 4.5 with vcore 1.27v,but when testing prime 95 cpuz just showing my vcore 1.240 to 1.248,running 2 hours no error,is that stable?should i test longer ?

BSOD codes for overclocking
Then confirmed it is insufficient vCore. Bump it up until no more BSOD.

Bro now no BSOD redi, intel burn test results as below:-

Settings:: HIGH


Settings:: VERY HIGH


i get a stable GFlops for both this test, but for my LinX i get around 60-70 GFlops, is it normal?. In addition i still get some very minor lag while playing FIFA

My Current OC Setting::



DRAM Voltage: 1.65v

60-70 GFlops is abnormal. You should get 120+ with 2500K, provided that you are using the LinX posted in post #1 and win7 SP1 onwards.

Ya im using the LinX posted in 1st post with Win7 SP1. Maybe increase Vcore a little more? currently @ 1.425v

Your screenshots are too small. Should have cropped them for better view.
Alright after zooming in your VERY HIGH level screen a little bit finally I could see your GFlops was actually started with ~125 then dropped to 60-70+ after a few loops. This shows that you're running at a performance drop, which is abnormal. Let's forget about the HIGH level as it doesn't really show max stress.
So try increasing your vCore slightly and see. There might be a possibility that there is something overheat on your board, that's why the performance is throttled down giving an inconsistent Gflops. You shoud monitor all the related temps with Asus AI Suite or any other temp monitoring app. Your core temps look fine as long as they don't hit TJmax of 98C.

Sorry for the low resolution screenshots bro my bad   bro aniway i ran LinX again yesterday increasing Vcore to 1.43. Increased GFlop around 130GF, but dropped again halfway, so i guess i am facing performance drop.

I dont get any warnings except for CPU. It always shows up a pop up "CPU 71-74 Centigrade".
This warning is intended for the CPU temps right?. Maybe i will try to run LinX again with the same setting with ASUS AI Suite running, will check if any overheat issues appear.

The mobo BIOS and AI Suite always record CPU temp, which is different from core temps. Normally we will pay attention on the core temps as it is related to TJmax. Nothing wrong with the CPU temps reading it works just normal.

What you need to look is at other temps such as mobo especially the VRM area, it tends to get hot at continuous stress. Make sure that your rig has a good air ventilation and flow. So that it doesn't get toasted so easily. From the pics seems like several critical points of your mobo around the CPU are normal. So it must be something else that cause the inconsistent GFlops and performance drop half way.

I could be a RAM issues. Having the GFlops cut to half is like a drop from dual channel to single channel bandwidth. Try running with 2 sticks (modules). Good luck.

hi,i want to ask this is normal for my oc ?i7 2600k vcore 1.272v,tq.

Oh I see, thank owikh84,so I can use the voltage all the way?or I should lower?i will test again with all mem.

Bro Owikh, i upped Vcore abit to 1.435, ran LinX and got a constant GFlop values 

so is my OC a pass nw? Btw 1.435 for 24/7 use safe for a 4.6Ghz OC or too high? so far lower Vcore gives lower results in LinX

Congratulations bro. Well done on the 130 GFlops! The vCore looks fine for average chip so you would be fine.
You got nice temps too so don't worry it is perfect for 24/7.
