I5 2500k msi z68ma-g45 b3 overclock settings

Hi, I recently bought an entire new setup minus the HDD (I'm saving up for a 200Gb SSD)

Basically I'm running this at the moment

SAPPHIRE Radeon HD 7950 OC 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card (11196-02-40G)

MSI Z68MA-G45 (B3) LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard with UEFI BIOS

Corsair Enthusiast Series 650-Watt 80 Plus Bronze Certified Power Supply Compatible with Intel Core i3, i5, i7 and AMD platforms

Intel Core i5-2500K Processor

Corsair Vengeance Blue 8 GB (2X4 GB) PC3-12800 1600mHz DDR3 240-Pin SDRAM Dual Channel Memory Kit

Aftermarket cooler 212 Coolmaster hyper

I'm not the smartest guy, but I did build this myself. Everything works get and boots up fine. I'm not looking to O.C my CPU & GPU.

Mainly the CPU for the moment, as the GPU is fairly new and I don't think I'll need a boost in that department for a few months.

Only thing I know how to do after reading dozens of threads and youtube videos is change the multiplier.

I've set it from 33x to 45x and the OS won't load. It freezes up and I have to reboot.

I tried changing the voltage from auto to 1.3200 and nothing.

Can anyone give me their settings for MSI Z68MA-G45 B3 Overclock settings?

Appreciate the help, just too many settings to tweak and I don't have too much money going around so if I mess with the settings and my PC blows up I'm out of a PC for a good 6 months.

  1. Try 1.365V and 45x multi
  2. Anytime I put the Voltage anywhere it overvolts causing my system to Idle @ around 3.7 - 3.8 V

    When I actually stress test it, HWMonitor shows it running at anywhere from 3.2 - 3.5 V

    I only did about 2 hours of Prime95 everything seems stable now @ 4.5 Ghz

    but I'm worried this out of control voltage thing is going to affect me in the long run.
  3. Also my idle temps while I'm afk and only apps open are

    Aim, Skype, Core temp.

    Are 30-45C, which doesn't seem right. Since my rooms AC is @ 60F 24/.7 and pointed near the PC
  4. Pictures please, it's impossible to run at that high voltage.
  5. Sorry I meant to put 1. before the other numbers. Everything is showing differently though. Pictures below.

  6. I have the G43 G3. I'm having trouble staying stable at 4200 MHz even with plenty of voltage. Don't expect too much from MSI's budget motherboards. I made a huge mistake.

    Also, you can't manually adjust vcore on these motherboards.
  7. ive got the same board and processor and i idle round 33c get up to 67c on Prime95 im currently clocked at 3.8Ghz and i never exceed 1.4v on full load

    in your Overclocking menu in BIOS settings you will find the CPU voltage setting its true you cant adjust the voltages specifically to what you want but you can specify that you dont want it to exceed a particular voltage

    set the voltage setting to not exceed 1.0000v

    i know that sounds low but trust me it works the board will still exceed the specified voltage but only a little bit hence the

    0.97v idle - 1.32v - full load

    hope you haven't thrown away that board yet
  8. I haven't, only reason I bought it is because my other mobo broke which cost me a ton, the PCI Express slot just stopped working. I'll most likely RMA that board and toss this one on ebay or get a refund if the RMA comes back quick.
  9. @Ric0_55 i forgot to mention i have a similar heatsink to yours TX3 coolermaster the size and dimension are exactly the same so your temps are a bit high

    the obvious cause are those out of control voltages driving your cpu temp up if you dont control or lower those voltages soon you are gonna be without a cpu or worst case without a entire pc

    anything about 1.5v is not healthy for your CPU you risk burning it out

    hope all this helps
