Overclocking Help plz i7-4770k Asrock z87 Extreme4 (now MSI Z87-G45)

post #1 of 86
Thread Starter 
Hello,

Im in desperate need of help. After reading reviews and accounts that even the worst batches of 4770k's should be able to hit 4.4Ghz im having a terrible time trying to accomplish that.

Rig:
i7-4770k
asrock z87 extreme4
H80i cooler (closed loop liquid)
case is rosewill redbone
H80i fans and rad pull from back into case, front case fan pulls in
2x 120mm fans on side push out
Win 8 Pro x64
16GB Kingston HyperX Beast 2133Mhz RAM (2x8GB)

Using the asrock built in 4.4Ghz preset everything seemed fine. Used the XMP 2133Mhz profile for the RAM. Windows 8 install fine, everything seemed to run ok.

Then played LoL, got a BSOD WHEA_UNCORRECTABLE_ERROR with a match or 2. Same with Hawken. Stock frequency these run fine, Prime95 reproduces errors when overclocked but not at stock.

Tried the 4.0Ghz auto OC and Prime95 did not produce the errors but CPUID HWMonitor was report temps of 90 degrees with the H80i's fans going at 2500rpm's. Stock the highest was ~65-70 (Stock was turbo boosting to 3.9Ghz it seems).

So I tired finding a guide or how-to with specific settings to get a stable OC. Could not find a single source online that specifies what specific settings to use for a manual OC.

As a side note, I have not OC'd for years (last time was a AMD 2500+). Any help with specific settings to try would be great. 4.0Ghz seems stable but the temps scare me. Id be perfectly happy with 4.4Ghz stable, not expecting to hit max OC.

Aside from specific OC setting, I also have following questions of somewhat less importance:
-Is it a cooling issue? I have AS5 (used H80i as it came), should I reseat the cooling block?
-Is it my RAM being 2133Mhz? Should I lower this?
-Is it a really poor quality i7? Should I try and exchange it?
-Is it likely my MB? Should I exchange for a different one?

Thanks for any help/suggestions.

I highly recommend this guide. http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition I used it to get to 4.4GHz stable. It should work just as well with Haswell.

It's still early in Haswell overclocking, so there isn't a whole lot of good guidance right now.  I would try adjusting your settings for Vcore and VIN (the CPU Input Voltage, whatever ASRock calls that).  Those two seem to have the most influence on  overclocking.  Vring (the ring bus voltage) also appears to play a part.  But my chip, at least, is very inconsistent, with tests passing one time I boot but then not the next. 

 

Temps are a big issue, especially once you get above 1.3V, and realistically 1.35V is probably going to be the limit on normal air/water cooling.  So I would try 1.3V and 44 for the multiplier, and see what that gets you on the temp side.  It may well be too hot at that speed and voltage.

 

I would run the RAM at 1600 while you dial in the overclock - no sense overclocking two things at once.  You also might want to limit your uncore speed (cache speed) to the default at first and then turn it up once you get stable.

Haswell is completely different.  I don't know how useful that guide is going to be beyond the basics of "increase voltage and test".

Thanks guys

I had seen the guide, and while it helps in a general sense with terminology and such I was hoping to find more along the lines of what to adjust specifically and by how much.

I had tried 44x at 1.3 and it wouldn't boot. Right now its 4.0Ghz using the built in preset for 4.0, haven't had issues with hawken or Metro LL. Would like to hit 4.4Ghz if possible

you might have to delid and replace internal TIM for better temps too.

o yea and the RAM is stock speed 2133, im not sure if on Haswell its still technically an OC because that's higher then the built in controller. I had considered dropping it to 1600 and then trying more OC settings on the CPU.

Yea delidding scares the hell out of me. turning a $350 cpu into a paperweight would make me jump off a building.

Yes, you can keep RAM low initially then dial it in later.

btw, read this post and pay attention to the Cache ratio tip especially but best is to read the whole thread too

Thanks, read the post there and it gave me some ideas. Ill dial back the RAM too and see if that helps. Ill post back my findings

Ok so RAM @ 1600 doesn't seem to help. 4.4 still crashes. I even tried the built in 4.2 and that wont boot. Getting same BSOD (WHEA_UNCORRECTABLE_ERROR). One time I got something like clock watchdog something.

Either I have a crap chip or more likely I have no idea which settings to hit to get a good OC.

Any help with specific settings to try would be great. Thanks

Seems like a lot of them just take a lot of voltage.  Try 1.33 or 1.35V (if you can keep the temps down).  Try 2.0V for the VRIN (CPU Input Voltage) and then try bumping the Vring by +0.05V or so.  It's really hit or miss still - not a lot of good guidance available right now.  Play with it, try different things, and maybe you'll be the lucky one that cracks the code.
