ASUS P8Z77-M not saving OC values + i5 3570K - Page 2

post #11 of 14
My Core i5-3570K is on a similar Asus board.

http://www.asus.com/Motherboards/P8Z77V_PRO/

I am using some 2 x 4GB of Corsair Vengeance 1600 MHz with 9-9-9-24 timings. It seems to work OK. It runs this speed at 1.50 Volts which I believe is the official Intel memory voltage spec for these CPUs. That Genesis RAM you are looking at might need 1.65 Volts.

Random lock ups and instability can often times be traced to bad memory. Have you done any Prime 95 Blend testing? That's a good way to work a lot of your memory. Lower your CPU overclock and make sure your RAM is stable. If it is not, try some new memory and test again.

Right about when 1 thing got in order, something other got screwed up.

All of a sudden, i couldnt do a Prime95 test, RAM_MENAGMENT error was popping up. I thought that my RAM was screwed up, but i tested it with memtest and it was all ok.

So in order to test it again, i reverted the clocks to its stock values, and only raised the clock a little bit. Then it was all okay, i wonder what am i doing wrong. Could you please post me screens of your BIOS settings? That way i can see what and where am i mistaking.

Thank you in advance.

Memtest is an OK test to make sure your computer is stable enough to install an operating system but beyond that, it's not a rigorous test of your CPU memory. Failing it is bad but passing it only means that you are ready to move on to the next test.

On my Asus board, I left the majority of the settings on AUTO. If I had infinite time I might be able to get my CPU running more efficiently or a degree or two cooler or a hair faster but I decided not to bother. 4.6 GHz takes a big step up in voltage so I stopped at 4.5 GHz. Like wise I could spend some more money on some faster memory, etc. but for my purposes, this isn't necessary. I decided to keep things as simple as possible.

On this board that meant raising the Turbo multipliers to 45 whether 1, 2, 3 or 4 cores are active, increase the CPU voltage until it was reasonably Prime and LinX stable, set the memory to DDR3-1600 MHz and that was about it.

Once I was happy with the overclock, I enabled the C3 and C6 core C States to reduce power consumption, did some more testing and called it a day. When you use C6, you can run a fixed voltage with no worries. Each CPU core will be spending over 99% of their idle time in the low power C6 state where voltage and power consumption for that core will approach zero. There's no need to go in search of the perfect offset voltage when you are using C6.

Here are some pics of my current bios settings.

With almost everything on AUTO, there are not any magic secrets but I hope it helps. I noticed that my memory Command Rate was set to 1 instead of the default of 2. That might make a slight difference in a memory benchmark but 2 or AUTO is fine for that.

What kind of memory are you running now and at what speed? Memory errors in Prime 95 is not a good sign. Try testing one module at a time to see if you can isolate the problem. You might have a bad stick.

I raised the clock to 4.35, @ 1.20v, ill maybe try to go further. It is stable now, i get some really good experience in gaming, i also boosted my GPU for 100 more GHz.. I raised the BCLK freq to 103, everything is ok now. I ran prime for like 1 hour, 85C was the most i that i got.

I played Batman Arkham Origins @ Ultra settings, pretty smooth. I also played BF4 @ High settings, no fps drops. I am really happy with my stuff now, finally.


Thank you so much for your help man, you are the best.

Best wishes,
X.
