3770K O/C not stable anymore

[Born_2_Kill_83]

It's possible for a machine to be able to complete Prime but still crash or have problems when gaming. Prime hammers your CPU with very specific patterns of usage; it's nothing like using the machine for actual gaming.

Sure it might give you a general idea of whether the system is stable or not, but you'll never know if it's completely stable without using it normally for a while.

Going to test my O/C in BF4 Beta tonight, see what temps I get in there and if its stable. If all is OK I may just leave it at 4.8 (winter is comming).

prime95 is gentle compared to linx and intel burn test

you won't notice much if any loss @ 4.6ghz

idk if your delidded op?

Its not delidded no, been thinking about doing this perhaps.

Did some more testing it appears anything near or over 1.3v my temps start going sky high in the 2nd batch of tests in prime.
I have down clocked to 4.6 @ 1.275v and the temps are nice and cool now (prime stable), the same as what they used to be at 4.8 @ 1.350v. Wonder why I have all this heat all of a sudden over 1.3v, probably causing me instability at 1.350v....

I could only just manage 4.6ghz with around 1.25v and was hitting 80-85c using a silver arrow air cooler so your's is about right

after delidding I could do 4.8ghz with 1.38v and 80c max,but it's risky as if you delidd it wrong you could kill the cpu ect

tbh I would stay at 4.6ghz,there's no real world difference other than bragging rights

use some coolaboratory liquid pro and you'll knock off a good 3-5c of any thermal paste out there

heat usually causes instability imo,could try a cmos clear/load optimised defaults and re apply your oc,using sli gpu's might need more cpu v also as apposed to a single card

I was also advised against running prime by 8 pack.

Do you run prime as a primary task for your PC?? Then your wasting time using it as a test.

Just use the PC as normal. No one cares about prime. Try your games!!! They crash adjust.

To be fair, prime crashes my system but nothing else does so in my case it was sound advice

 

[wazza300]

that's mostly down to haswell not being capable of running prime ^^ it gets too hot

older chips are fine

Fair enough

So my 4.8 @ 1.350 volt proves unstable again last night while playing the BF4 could this be cause my temps where hitting 91c? Saying that it could just be cause its Beta.

Seems I'm going to have to turn it down ran 4.6 @ 1.250 for an hour and all was fine with temps never getting above 77c. Just gutting when Ive ran 4.8 for so long.

Asure me I'm not loosing any FPS in game and I think I can live with it.....will my CF7970GHZ be more bottle necked?

Cheers for your help people.

I really don't think that you will notice a difference it will probably be as little as 5 fps and that could easily be made up for in different ways.

 

[Born_2_Kill_83]

5FPS!!!! Thats a massive amount for 200mhz

 

[wazza300]

have you cleaned out the heatsink? maybe you can get lower temps?

when it crashes does it crash to desktop? look in event viewer/custom views to see what warnings/errors crop up related to cpu and or memory

 

[Born_2_Kill_83]

Yeah cleaned the cooler and reseated, didnt make any difference to temps

I got 2 BSOD with error code 5110A, and 2 CTD/Program not responding, sound like O/C's?

Im happy to make that assumption, my 4.6 @ 1.250v has been fine on all other games I play, For the BF4 beta it just doesn't like 4.6 I only had 2 BSOD's yesterday but still it was enough to annoy me

With my 4.8 the game will run for 10-20mins fine and then either CTD or BSOD/lockup. Shall we put it down to the beta then? Surely if the O/C was unstable it would have done it before now in other games and sooner than 20 min's of gameplay. Saying that maybe BF4 is stressing our CPU in a different way and finding stablility issues that havent come to light before?

What are the temps at this point?

 

[Born_2_Kill_83]

The hottest core hits 88-90c after 20 mins of gameplay, averaging 80-84c during this time (hottest core again)

 

[wazza300]

it's too hot for general gaming imo

mid 60's is acceptable

no idea what those error codes are but one to look for in event viewer is cpu parity 19 whea warning/error that's common for not enough cpu voltage

get some coolaboratory liquid pro to reduce temps slightly but do do any real good you need to delid,i don't go above 60c @4.8ghz while gaming

bso'd codes I know of are 0x0000000124 error not enough cpu v/or cpu/vtt

0x00000000101 error not enough cpu/vtt
0x00000000050 again not enough cpu v

Ok clocked her down to [email protected] and been playing BF4 Beta for 2 hours and no crashes at that setting, maximum temps on hottest core get to around 72c. I'd rather a safe stable overclock at the end of the day, hopefully the full release will give me a few more FPS, atm I'm getting an average of 70FPS so that'll do.
