1055t Overclock NEED HELP! Prime 95 Freeze - Page 2

post #11 of 21
^ I encountered similar behavior as the above on my old Asrock M3A790GX which also had a 4+1 VRM setup (without aftermarket heatsinks they were hot enough to roast off your fingerprints).

3.7 is about the limit that I was able to get my 1100T on my 4+1 motherboard with custom VRM heatsinks and a fan on them.

or you can sell that board add a little money and get a beter board for over clocking

I cant even overclock to 3.6ghz at the moment without my system freezing up =(

Could it be due to ram timings? their the only thing i havnt adjusted..

you would see a performance gain by oc'ing your cpu/nb to somewhere close to the 3000mhz range....it will also aide in stablizing your cpu oc....a oc with 3.6ghz cpu and 2900mhz cpu/nb will perform better than 3.8ghz cpu and 2300mhz cpu/nb ...and since your limited to your cpu oc the better you can get your cpu/nb the better your overall performance will be thumb.gif

the cpu/nb oc will also help with ram

While this is all true, the limiting factor in this case is the inadequate motherboard VRM system.

Back on my old MSI 4+1 board I hit 4.2ghz with the same chip. The VRMS overheated, but it was stable. I have the same motherboard, I would try disabling LLC if it isn't already and then try again. I also needed over 1.5v to hit 4ghz. 1.52 is what I had it at for a constant 4ghz, which may have been a bit high, but it worked until I pushed it further. The VRMS on Asrock boards are renown as being incredibly high quality, and you should be fine at 4ghz, but there still is always a degree of risk.

I would try it with LLC off, and try to raise the vcore to 1.48 or 1.49v, and test there.

The 970 Extreme3 has a cooled and good quality 4+1 phase VRM system (akin to the one on the 970 Extreme4).  Where 4+1 phase VRM systems are a problem with 125W TDP processors is when there is no cooling (i.e. M3A770DE mentioned above) or when (on top of that?) the design is mediocre and failure prone (i.e MSI board above).

 

By the way, the lower overclock result may be a result of differences in motherboard.  If the sound chip on your Extreme3 is different from your other board and might be more strenuous on the CPU it may be holding back your overclock (yes, integrated sound cards can hold back overclocking potential because sound processing is done on CPU).  A sound card will help here.  Given that your board is probably of a newer chipset than the old one (970 vs whatever?) it should overclock better when misc issues like sound are aside.

all the more reason to get performance where you can without having to oc cpu.....you should be able to hit 2700mhz to 2800mhz with 1.3v....it will be a very significant boost in performance compared to a few more 100mhz for cpu thumb.gif
