Let's forget the vcore setting in the BIOS: what does CPU-Z say your vcore is while running Prime95 when it's set to 1.340V in the BIOS?
What is your Load-Line Calibration setting?

(Solved) OC i5 2500k prime95 test kept getting fatal error
hello guys a newb needs an input please
![smile.gif]()
so i finally OC my cpu to 4.4 and have been running prime95 for 3 hours without any issues. but when i try to run it again (while opening steam,mozilla,and IDM) it crash BSOD crash.
here some of my settings : EMP disabled,thremal monitor disabled, turbo power limit 250, core current limit 250. CPU PLL 1.650, Vcore 1.340.
but after 5 hours or so i always ended up with core no.4 with 1 fatal error while the other 3 cores still active.
temp with prime hits 77 max.. gaming and such around 60s, standby at 40-50.
i live in tropical country so its quite hot here
ps: ive tried running prime95 with 1.320V resulting in BSOD,1.330V got me 1 error (core no.4 as i mentioned),and 1.340V still on testing

(remember you were helping me with SSD and defragment issues a while back)
1.i use CPUID hardware monitor and the value CPU vcore are at 1.320V
2.i dont know about Load-Line Calibration setting(care do elaborate?)
3.could the error or bsod crashing appear when i run prime95 because i open another program too? (like i mentioned i open mozilla,steam download and a download manager at the same time while i run prime 95)
thank you for replying:thumb:

So to be clear, is it 1.320V with it set to 1.340V in the BIOS?
The Load-Line Calibration setting may also be called LLC or even vDroop control.
I don't know enough to know if the Prime95 problem is caused by opening another program during the test. I kind of wonder if it's just a lack of voltage because 1.320V is a little tiny bit on the low side for 4.4 GHz.
Oh hey dude!Originally Posted by goodman1280

i use auto on LLC i believe, and yes i set 1.340V on vcore at BIOS. and when i run prime95 my Vcore value is 1.320, min is 1.320 and max is 1.332Originally Posted by TwoCables

Hmm. Try a a slightly higher core voltage, like one that ends up getting the 1.320 voltage up to maybe 1.340+ (no coincidence intended).Originally Posted by goodman1280

and how much vcore usually a 4.4 GHz need? or most people put it?? approximate would be nice idea for me so i dont increase it too much (and i saw that u got 1.368v for 4.7 GHz?)
so in order to be fully stable i just need to increase Vcore bit by bit and kept testing using prime95 to each volt i increase? ex: so the next i should try 1.350-1.360 and so on until its stable,yes?Originally Posted by TwoCables

Anyway, I'm going mostly by 4.5 GHz, and the most common voltage I've ever seen on here for 4.5 GHz is about 1.352V. So I think that 1.320-1.332V has to be pretty low for 4.4 GHz because that's a much smaller difference for the CPU than 4.7 GHz and 4.8 GHz (as you can see by the huge voltage increase mine needs hehe).
Well, that's my hope anyway.Originally Posted by goodman1280

Yep, 1.368V is what works for mine. Then to go to 4.8, it needs 1.392-1.400V. lolOriginally Posted by goodman1280

i wonder if i put 1.350v its still going to use 1.320v then what's the point?
thanks so much for helping, i guess im going to kept on 1.340 as for now my prime95 test hasnt got any error/crash yet.. if that's happen ill put 1.350v... btw if i set 1.340v vcore on bios then why is it only use 1.320v as my value when running prime? shouldnt it be 1.340v??Originally Posted by TwoCables

That's vDroop, and it's normal. If you set it to 1.350V, then you'll either get a slightly higher voltage than 1.320V, or a "lot" higher (but not more than 1.350V).
Anyway, I am glad that it's working so far as it is. It's a nice low voltage.

Hi! lo bkln test prime95 brp lama? gw rekomen 12 hr prime95 blend mode.

... iya uda di tinggalin dari semalem ngetestnya, almost 12 hrs now and im about to paused it

denger2 24 jam lebih akurat lagi ?? kamu dulunya ngetes berapa lama?
sori br bgn tidurOriginally Posted by Miss Roxy

Ya 24 hour lebih akurat... tapi menurutku 12 hr sudah cukup karena prime 95 blend selesai test nya at 11 / 12 hour mark.Originally Posted by goodman1280

, btw how come you've managed to put only 1.256v on vcore while push it to 4.5 ? on the other hand i need to put close to 1.350v to get to 4.5 GHz,
that's 0.1 difference..

Every chip is different. There are a number of 2500k that can overclock below the average volt and there are some that needs more volt in order to be stable.Originally Posted by goodman1280

1.35 isn't that bad for a 2500k at 4.5 ( around average i would think). I believe mine is 1.312-1.320 ( cpuz reading, bios is 1.320) for 4.5. I run 4.4 tho, because it only needs 1.272 to be stable. Also lower temps. Unleash it and have some fun gaming now.
