My MB is MSI z97 g43 with a CM Hyper TX3 evo cooler.
Following the guide to OC haswell chips I enabled advanced mode in bios, locked the ring ratio at 32, set ram to ddr3-1600 MHz, and started upping the CPU ratio. Im running with vcore at 1.295, since I'm after the highest possible 24/7 settings, but have tried going to 1.3 as well, but I just cant seem to get it stable even at 4Ghz. After about half an hour playing WoW it will reboot, refering to bad OC settings. This also happened using OC Genie.
The settings shown below is the highest I've been able to go over a few hours, and even now HWMonitor shows max temps at 76C sometime during my last 2 hr gamingsession which I think is a bit on the high end. As im writing this temps are ~43C. I have refit the cpu cooler just in case i botched it the first time, but it hasnt made any difference
I currently dont have any issues running WoW smoothly (I settle with 30 fps steady in raids
), but I cant help being a bit jealous of other posters here reaching higher clocks, seemingly without any problems.
First thing I notice off the bat is you haven't raised your VCCIN, it's a good rule of thumb that VCCIN should always be .500 more than vcore. Looking at the screenshot you should raise your vccin a bit and see if that helps stability. Also 76c is pretty high for just gaming temps with that overclock. With a 4.5ghz overclock and 42ring on my rig I don't exceed temps of above 50c gaming on Alan Wake, Endless Legend etc. my cpu is underwater though. You can always do the quick and dirty method and set VCCIN to 1.900 and vcore to 1.300, leave ring locked at x32 and ring voltage at stock for now. then select your target multiplier and see if it will boot up, if so run a stress test for stability making sure to keep an eye on themps, if all goes well begin to lower voltage in increments of .010 until it becomes unstable again then raise it up to the previous number. after that do the same with VCCIN until you're zoned in. THEN move onto overclocking the ring.
p.s. leaving your power settings in WIndows on balanced will affect overclock stability, set it to high performance.
So I spent a good 5 hours today dialing in my good chip to get some solid numbers for temps after delidding. Her are my results after 2 passes of intel burn test and one pass of x264.
CPU Multiplier = x47
Ring multiplier = x44
VCCIN = 1.900
Vcore = 1.375
Vring = 1.250
Idle Temp = 35c
Intel Burn Test Temp = 80c
With these settings running Intels Burn test I reached temps of a solid 80c, temps on x264 were lower. Gaming on these settings I saw temps in the mid 50c range at the highest. trying x48 at 1.4vcore boots up but is a bit unstable so I toned it back to 4.7, what's 100mhz when you already have a 47% increase in performance
I wanted to validate it but this board doesn't display my vcore properly in cpuz. If you guys want to see screenshots let me know.Question
I purchased 2x4GB PC1600 Mushkin Blackline Enhanced ram, I understand the g3258 only supports up to pc1333 and I can see it's been toned down in cpuz to 666.5mhz, so it's running at pc1333. The MSI H81M-P33 board I'm using however supports PC1600, should I even bother overclocking the memory to it's rated pc1600 to see if I gain any performance? Will it work since the cpu only supports pc1333?Edited by DotBeta - 10/8/14 at 1:52pm
