ok I have a 1055t and I have a stock liquid cooling system. My friend oc'd it for me to 2.0 to 3.5. I want to get it to 4.0 how do I do this safely?

And im a noob on ocing so if you know how to do it please tell me in steps. I dunno if my cooling system is ok or anything. I do got cpz-z and stuff so I can link pics of the volts and whatever you need to know.

Once you reply I will respond immediately. I will not waste your valuable help and time.

It all depends on how high you need to bump voltage to get there and how hot your CPU will get once you give it the extra voltage.

There is also the very real possibility that your chip can't get to 4Ghz. (Not all 1055's can)

So if you want to try and go faster here's a cut-n-paste from another post I made a while back. The values will be different because you are trying to push beyond where I left off, but the procedure is the same.

Also, before you make any changes, save your current overclock profile in your BIOS if you have that feature. 3.5 is a pretty nice overclock to begin with and you don't want to have to figure it out again if you have to reset to factory defaults because you pushed too far. If you can't save it, take a bunch of screen shots from the section you intend to make changes in before you change anything.

On to the cut and paste.....


I have my 1045t OC'd to 3.4 Ghz with all 6 cores running. It could go higher but, I'm limited by heat because I can't fit a bigger cooler in my case.

I recommend getting some free software first. CPU-Z and HWmonitor, and prime95.

CPU-Z will show you frequencies, voltages and ram timings.

HWmonitor will show you temps. *Be warned* HWmonitor was showing my core temps 10 degrees lower than they actually were. The temp labeled "TMPIN2" was actually tracking perfectly with the core temps shown in AMD Overdive. So look for the highest temperature other than your video card. (many video cards can safely run at hotter temps than your CPU.) The hottest one on my Gigabyte 990 fxa ud3 (other than the video card) is the core temp. Try to keep it below 55C under full load.

Prime95 is the program that will stress test your computer to see if it can remain stable and cool under load. 2hrs of the blend test with no errors and no overheating is a general rule of thumb for a stable OC.

Now for the fun stuff.

Go into your BIOS and lower the multiples for your CPU and your Ram by a few steps. (The 1045t won't let you increase the multiplier above stock)
Then disable turbo (aka "core performance boost" )
Then find your CPU Host clock control and set it to "manual"
Then You should be able to change the "CPU Frequency" (I'll call it FSB) (This is before the multiplier, so it will be low. Mine started at 200)
Now increase that variable by a bit.

I recommend balancing your FSB and your "memory clock" (RAM) multiplier to a point where your ram is back down to stock speeds after you bump the FSB. So raise your FSB to something like 250 then adjust your RAM multiplier down so that your RAM us running at or near stock speeds.

Now move on to your CPU clock ratio. With the faster FSB, you will be able to run your CPU at higher frequencies with a lower-than-stock multiplier. I eventually took mine all the way back up to 13.5 with a final frequency of 3.4 Ghz.

I would recommend starting with a lower multiple that gets you just a couple hundred Mhz boost over stock at first. Then test for stability and heat. Run prime 95 for at least 30 minutes if you want to see your hottest temps. The blend doesn't get things hot until about the third bank of tests.

If things look good, go back into the BIOS and bump the multiplier some more and re-test.

My MB got rather ambitious with the voltages when I left it in auto, so use CPU-Z to keep an eye on core voltages. Many recommend just staying under 1.45 volts. I recommend not going any higher than you need to for a given clock speed. This will help keep heat down. I ended up using a negative offset "CPU voltage control" of -0.075 volts. This brought my core voltages down to about 1.344v at full load.

*note* I'm scraping the floor on voltage with my particular chip/speed. One notch lower and I get BSOD. You may be able to go a little lower or you may need a little more voltage for your chip and clock speed.

Now just test and adjust and repeat.

Generally speaking:

BSOD means you need more voltage, and/or less speed.

Overheating means you need less voltage and/or less speed. (or a better cooler for your CPU.)

If you get to the point where your temps are good and your computer is sable, and you still want to go faster (than ~3.4Ghz), you can go back and bump up the FSB. But remember to adjust your RAM multiplier back down to stock-ish speeds.

You can OC your RAM later, but that gets a little more complicated as you may have to adjust CAS timings and RAM voltages to make it work. Keeping your RAM at stock speeds should give you one less thing to worry about while you probe the limits of your CPU.

Good luck!

anyways... is it safe to do it with the motherboard I have. If I upload my temps and volts could you just give me a number.

I don't see your motherboard in the OP. If you upload your info, I can give you an idea of how much headroom you have.

should I take pics of my bios and cpu-z while running a game? and got a stock liquid cooler thats like 120mm something from Ibuypower.


this is cpu-z while planet side 2 is running. My friend sayd he oc'd it to 3.5 but it only shows 2.8 ghz.. whats up with that?



ALSO it says 1050t when I boot up my bios it says 1055t. is cpu-z not accurate?

Motherboard looks good. For temps, you need to run a stress test to find the max temps. Intel burn test or Prime 95 should work. Run at least 30 minutes of either to find your max temps.

I dunno how to do temp protection. I dunno if you want me to overclock it with a program like msi or within the bios. I just want someone to tell me exactly what to do as im doing it. I can stream would that work?? if you got the time? I can also post my bios just tell me what to post and what values to change please.

ok so run prime 95 right now? without doing anything first so you can see my stuff?





in prime95 what should I do to test please?





ok I just got prime95 and I have no idea how it works. Could you tell me how to in steps?


Im gunna livecast my stream and ill wait for you guys in my chat. ill do EVERYTHING you tell me and I got vent,skype,ts,mumble so we can voice chat too. I got all day to do this I just have never done this myself.

twitch.tv/lgnpsycho - LIVE waiting for you guys

Just got back to computer to see your message. Overclocking is a lot of trial and error. Testing and adjusting.

We would be on your live feed forever trying to do this.

Use your BIOS and do the steps I laid out in my first post in this thread. It will take some time.
