OC i5 2500K, BSOD issues?

Hey all.

Was wondering if anyone could give me any pointers please, I only know the basics of overclocking etc, I brought a pre made bundle which was an i5 2500K stock 3.3Ghz overclocked to 4.5Ghz.

The system came with a H60 watercooler.

I have had it nearly 3 years now, and recently (usually playing microsoft flight simulator X) I am getting frequent BSODs.

LL


Now, i have ran a few tests;

Firstly, I used FurMark to check my GPU, and it passed with no issues at all.

I then ran Prime95, On the ''blend'' test, and it crashed causing the BSOD in about 2 mins.

I took one of the RAM out to check, it did it again, then replaced with the other and it did it yet again.

I then put the stock profile on, and no issues arisen.

I have noticed recently that when i switch the PC on, it sometimes goes straight off again and usually restarts automatically (that may be of no relevance not sure).


So basically, I am stuck and really need some help if anyone has any ideas?

(My idle Vcore is around 1.176v)

Specs:

-Coolermaster 692 Advanced White gaming tower
-Intel Core i5 2500K 3.3Ghz stock Overclocked to 4.5Ghz (brought as pre made bundle at ************, tested etc.)
-Corsair H60 Watercooler
-GByte GA-P67A-D3-B3 MoBo
-8GB, 2x 4GB RAM
-1TB Samsung SATA HDD
-650w NZXT Hale Gold Modular PSU
-1024MB Gainward GTX 560 Ti Phantom.

Cheers, Adam
 
Snips,

Cheers mate. I take it this is defo CPU related then, Voltage perhaps?

So i need to increase my Vcore slightly correct?

Also i am in thinking of getting the hydro h100i water cooler, have heard this will be much better than my current H60.

Cheers
 
Ive gone into BIOS (MIT)

On the overclocked profile

My Vcore is 1.320v
DRAM voltage 1.536v
CPU temp 32 oc
BCLK 100.32MHz
CPU Frequency 4514 mhz
Memory Frequency 1605.18MHz
Memory Size 8192 MB


Ok,

at 100% the vcore in cpuz was 1.188v, and the cpu temp went upto around 67 degrees c, i stopped it then.

Do i need a new watercooler perhaps?? Is the CPU getting that hot that its causing the BSOD.... Im unsure

Do these look alright?

67c is fine...keep under 80c

1.118v in cpuz at full load is too low...do you have a load line calibration setting in bios?
It compensates for vdroop where voltage drops under load.

what does cpuz show at idle?
I set mine to level 7 but depends on the board you have.
Need to set it so that vcore stays the same under load.

If its still crashing at 1.32v then raise it a bit.
Mines at 1.38v for 4.6GHz but every cpu is different.

Get it stable then work on lowering it.

Temps seem a bit high right enough for a watercooler but no experience with them but should be lower i think esp at that voltage...what were your temps like before?

Would normally say test using memtest first but failing a typo the vcore is way too low for that speed.
 
try

high llc
100 bclk
cpu voltage set to normal
dvid try +0.020v

then see what load cpu v is in cpu-z while stressing
 
Hi postman

My question is why did cpuz show 1.188v at full load but in bios it said my vcore was 1.320v??

The idle vcore according to cpuz is 1.176v

Cheers
 
vcore cant be set at 1.32v then...must be set at 1.2v (approx) :(

Bios setting isnt taking effect in the operating system....does it show the vcore in bios health bit? where it shows temps etc not the overclocking bit?

I would reset the bios using cmos jumper/switch on the board. (with all power disconnected and motherboard battery out)

edit: could be a false reading in cpu-z so try something else...not core temp as that reports mine wrong

The readings in bios were in the MIT page at the bottom..

Cpuz defo shows different to what the page on MIT says for some reason..

I have ordered a new watercooler, ill add new as5 paste aswell, then either try an lower the mhz or try to increase the vcore... Do you think this is good idea?

Cheers
 
Must be cpu-z not reading it correct then...never had issue with it myself before in my gig board...what version are you using of cpu-z? on 1.69.2 here

Whats the max temp it hits with prime?

How long did it take to hit 67c?

67 is ok but i have mine set in bios to shut down at 80c just to be safe.

I hit mid 70s max with good (at the time) aircooling

If it crashes under 80c then its not temp causing the problem.

edit: takes about 3 or 4 mins for mine to hit max

it might be the default vid of the chip

chips can be undervolted but 1.188v seems low for 4.5ghz unless its a golden cpu (good clocker)

temps are ok at 67c

did you try the settings I gave you? you should also be able to take screenshots of the bios pages/settings with a memory stick and pressing f12 key
 
Having had my 2500k at 4.5ghz for ~2 years on a corsair H70 I started to get some BSODs recently. Temps are fine, voltage was offset at a smidge below stock. Increasing to stock voltage didn't seem to help and I didn't fancy increasing it. Dropped the OC to 4.4 and the voltage back down and it's been fine ever since.

Funnily enough it never did it under hard load, just when using windows and office usually (That's unsurprising in some respects, I was spending most of my life using office.)
 
touch more voltage over stock wont hurt,i run my 2600k at 1.344v for 4.5ghz (using offset) and no crashes at idle

depends on each chip
