2500k wont overclock :(

[SavageCupcake]

hi guys

recently got a 2500k and some exelram 8gb http://www.aria.co.uk/Products/Components/Memory+-+RAM/DDR3/Dual+Channel+-+%281600MHz%29/8GB+Exceleram+Value+Series+LP+E30141A+%282x4GB%29+1600+%28PC3-12800%29+240-Pin+DDR3+SDRAM+CAS+9-9-9-24+1.5V+?productId=49809

thats the link

im trying to get the 2500k stable at 4.3ghz and even at 1.3v plus its blue screening even when my mum plays bejewled blitz on fb, but the wierd thing is i ran prime 95 for 3 hours last night and it didnt blue screen once yet i boot it up when i come home and it blue screens within a minute

getting quite annoyed now, been waiting for this cpu for agessssss

any ideas guys? my mates got his 2600k at 4.4 on 1.3v. i know about the chip lottery but it cant be this bad?

Needz mo volts

Go for 4.5ghz 1.35v.

 

[SavageCupcake]

right i just set it to 1.34 volts in the msi bios and its running prime 95 but cpu-z reports 1.27 volts? :/

 

[SieB]

Do you have speed step enabled? that could be why CPU-Z is showing different.

 

[SavageCupcake]

didnt see an option for it in the bios. isnt that the thing that slows down the cpu and drops the volts under low load? because im running prime 95 now with cpu @ 100% and its still saying 1.27 volts

 

[SieB]

Yeah, speedstep lowers the volts depending on how much load your CPU is under, it might be under C5 stepping in your BIOS.

Strange it's only showing 1.27v under full load though, check your version of CPU-Z is up to date, other than that I can't think of why it's not showing the same as in the BIOS.

ah ok ill have a look later

how long should i run prime for? would an hour be ok?

 

[SieB]

People say between 4hrs - 24hrs, in my opinion though if it hasn't crashed after 1 hour then i'd say you are ok.

Personally though, if my PC doesn't crash doing the things I do on it then to me it's stable, I never bother testing with Prime, but thats just me.

 

[SavageCupcake]

i was thinking that, most intensive thing i do really is play bf3

ill run it till 5 and if it doesnt crash its stable for me

thanks for the help mate

my 2500Κ runs at higher voltage (1.200V - 4.1Ghz ) when idle than when stressed (1.144V) . isn't that weird?

Another important thing: Disable turbo.

If you have an asus board download AI suite II, it will pretty much tell you if you lost the chip lotto.

 

[SavageCupcake]

nope ive got a msi z68a gd55 g3

any other ways to tell?

 

[airdeano]

im finding that using the intel burn test weeds some prime95 weaknesses out.

running 5-8 consecutivly pretty makes the CPU feel the squeeze. thats just a

thing ive been working with. i still use prime95, but not as much. OCCT for a

LinPAK for CPU/MEM test. and MMETest for strickly memory.

I ran prime for about 8 hours. You can use F@H as as stress test as well if you want

Someone on Specialtech is having the same thing with theirs, or is that you as well?
