Help - My computer randomly freezes with no bluescreen or anything.

post #1 of 9
Thread Starter 
Hello guys. Im new here and kinda new to the whole overclocking.

Maybe anyone here can give me some starter help?

Here is a list of my computer parts:

Cabinet - In Win H-Frame Open-Air design
Motherboard - ASUS Maximus VI Extreme
SSD - Kingston SVP200S3 120G
RAM - Corsair Vengeance Pro DDR3 2400MHz 16GB
CPU - Intel Core i7-4770K Processor
GPU - 2x ASUS Radeon R9 280X DirectCU II CrossFire
PSU - Corsair AX 1200i, 1200W
Cooling - Silverstone Tundra TD03
Headset - SteelSeries Siberia v2 Frost Blue
Keyboard - Mad Catz S.T.R.I.K.E.7
Mouse - Corsair Vengeance M95 Performance
PC Speakers - Corsair Gaming Audio Series SP2500

Im trying to make my rig stable at 4.2GHz (pref higher if possible) but i keep getting random freezes no matter what i do.

Sometimes i can play battlefield 4 for hours with no problem at all. other times it freeze after only 30min. It also freezes from time to time even if i dont use it for anything special or use it for simple stuff like watching a stream at twitch.tv.

The cpu temp is around 38-42 celcius when im only browsing the web or doing simple things.

Can go up to around 48 celcius if i run games like world of warcraft, league of legends or heartstone.

If i play more demanding games like Battlefield 4 i reach around 55-60 celsius.

During stress tests like "Intel(R) Extreme Tuning Utility" and "AIDA64 Extreme Edition" i reach around:
72-75 celcius at 4.3Ghz with cpu voltage at 1.27V and ram at 2400mhz
70ish celcius at 4.2Ghz with cpu voltage at 1.25V and ram at 2400mhz

Im currently running my overclock at:

sync all cores: 42
cpu cache: 41
ram runs at: 1866mhz
cpu voltage: 1.27v


I have tryed many different overclock settings and it allways boots up and runs for a while. passes stress tests from Intel(R) Extreme Tuning Utility even at 4.3Ghz with 2400mhz ram and cpu voltage at 1.27v

Beside this the only thing i have changed in my bios was disabling the intergrated graphic memory in my cpu under some advance settings.

All my drivers are up to date including my bios.

I just want to know if it is anything i might have missed? Something i should change?

My computer is only around 2month old. Exept my SSD harddisk witch is around 1 year old.

Anyway thanks alot for all the help i can get.

**edit - might be note worthy to mention that my rig fails stresstests and freezes if i try to run it at 4.4ghz and it wont boot at all at 4.5ghz. Atleast not with any current settings i have found**

so can you confirm these freezes don't occur when the cpu is at stock clocks?

also, prime is a pretty good burn-in tool that will expose unstable cores pretty easily, its also quite easy to have said instability inside windows without you even noticing;
http://www.overclock.net/t/137251/prime95

usually Ive found windows (or at least windows 8) will give a BSOD if the cpu isn't stable enough, have you run memtest on your RAM too to be sure that's working at 2400 properly too?

that might be all I can help you with for now, haven't touched any of the newer intel processors...

Yeah there is no freeze if i turn the computer down to the stock settings.
My ram bricks should be working at 2400Mhz since theyr sold as 2400Mhz bricks. Or am i wrong there?

Here is a link to my ram bricks: http://www.corsair.com/us/memory-by-product-family/vengeance-pro-series-memory/vengeance-pro-series-16gb-2-x-8gb-ddr3-dram-2400mhz-c10-memory-kit-cmy16gx3m2a2400c10r.html

I have been watching some of the guides i find from haswell and been reading alot on the republic of gamers forum and i just wonder if there might be some small details i might be missing?

Also i went over my bios today and see that i have my dram voltage at 1.65v instead of Auto as it is by stock. Don't know if that makes much difference. I just saw that haswell guy saying it was better like that in one of the guides.
post #4 of 9
with haswell the higher your cpu overclock the lower your ram speed you might just have bad luck. some guy's just to reach 4.5ghz oc have to lower their ram speed to 1600mhz to be stable on 2400mhz ram
post #5 of 9
also that ram is not on your motherboards QVL you might want to see if there's a bios update for your motherboard that remedies this problem

Hmm ok is there any huge diffrence in performance while playing games and stuff? I got a freeze today from the settings i ran in my previous post and are now running at:

Cpu sync all cores: 4Ghz
Cpu cache: 4Ghz
Ram: 2400Mhz

Cpu voltage: 1.27v
Dram voltage: 1.65v

I doubt it will freeze or anything at these settings. I just wish i could push my computer further.

just cause the RAM is advertised at 2400, doesn't mean its stable at that, you have to be sure the timings are set correctly and you should run a memtest overnight to be sure, its completely possible that sticks can be "defective" at their OC clocks but not the DDR3 stock 1333, first hand experience, you do a warranty RMA if that's the case.

you also have to watch your cpu with said ram clocks, they are outside intel's specs so are not only not supported by intel, but you most likely need to add more voltage, in the case of our AMD rigs we push the CPU/NB voltage up (yes this is actually inside the CPU, we have two CPU voltages), you would have to look at some intel overclocking guides for this though...

so the clocks that give you grief, leave your rig at that and run memtest and see what happens, if errors pop up lower the cpu clock back down and test again, if errors pop up again you may need to RMA your RAM or try loosening the timings to work out whats actually happening.

Your problem is probably VVT and/or VCCSA related. A setting that many people overlook when they try to run memory at higher memory frequencies coupled with above average overclocks. Just by scanning through your post and seeing the kind of hard freezes you are getting. I can almost be sure that it is VVT/VCCSA related (memory related).

Try DRAM voltage @ 1.65v, VVT @ 1.168, and VCCSA @ 1.200v these memory setting should be more than enough for 4.4/4.5GHz with memory @ 2400MHz (also make sure when setting frequency, you initially enable XMP profile to get correct memory timings - then set correct frequency after that if it already hasn't applied).

Start there.

Also, always update your motherboard Bios to newest version. Something that must be done, before even installing Windows.

yea that sounds to be what I'm trying to refer to, essentially you need to give the memory controller components in the CPU a little more power to handle the RAM frequency alongside a slight CPU core overclock. so try that and see how it goes.
