1075t Help pls!

post #1 of 7
Thread Starter 
Hi I'm an overclocking newbie and i am in need of lots of help!

I have an amd 1075t processor
Motherboard: MSI 870a-g54
Memory: gskill ripjaws ddr3 1600mhz( for some reason my memory says its default voltage is 1.5... but If i run it at 1.5 then i get blue screens and has been stable at 1.66 for a couple of months now).
stock fan

At the moment I am at 3.8ghz and HT of 2032 and the multiplier is at x8.
The vcore is at 1.51(which i realize is high, but if i lower it anymore I get blue screens within a couple minutes of startup)
The memory is at 1.66v @1355 mhz ratio of 1:2.66
The cpu-nb voltage is on auto @1.162v

My computer has not blue screened on me yet with these settings, but I did get errors in amd overdrive.

Please look at my pictures below and help me find out what i'm doing wrong! I really don't know what to set the voltages at. And maybe my memory ratio is too high?

Any help is appreciated, thanks!

The x8 is your CPU-NB multiplier, not your CPU multiplier. Your CPU multiplier is set to Auto and is showing as x15. Set it manually and see what happens, first of all. Then test with prime95 for at least 24 hours to see if it truly is stable. I also manually set all voltages, especially CPU-NB since I see the biggest stability problems when that drops too low.

CPU-NB voltage set to maually. For instance, for my systems stability, my CPU is 1.475v at 4.0 and NB is at 3000mhz with 1.45v. When you raise the speed of your cpu, your NB needs to be a bit faster to help communicate better with your ram, as it needs to communicate faster, it needs more juice. This should help you lower your CPU v

As said above, set your multi manually.

What kind of cooler do you have?

1.51 is wayyyy way too much. It's not the lack of voltage causing blue screens. Set your NB at stock 2000MHz. Set your ram low for now. (1333 or less)

Start by bumping cpu to 3.8 like you have already. Try using only around 1.45V.

If thats stable you can start playing around with ram and CPU NB. For 24/7 I recommend the NB freq to be between 2600 and 3000. I'd set it to like 2750 with 1.250 volts (the voltage to adjust this is called CPU/NB voltage not NB voltage). Need around 1.35V+ for 3000MHz.

Then set memory to 1333MHz 7-7-7-20 and try that. Run Prime 95. Fool around with the settings a bit till you get prime stable for 3 hours minimum. make sure memory voltage is at stock as well.

Make sure that you stay below 60C under load. Temperatures read from coretemp (if you use it) are inaccurate and you must add around 12C to the displayed temp to get your real temp.

The cpu multiplier was set on auto @15x. I changed it to manual, but the highest it goes is still 15x. As for the voltages, what do you suggest i set my cpu voltage at and my cpu-nb voltage at to start with?

Every chip is different. They all have their own quarks. I would suggest starting small. Start at stock and bump your FSB up 5 or so and boot and see how that works for a few minutes. If you can get into windows fine and open prime95 for 5 min or so. Restart and add another 5 to your FSB. You will get to a point where you wont be able to boot into windows at all by doing this, usually its just add alittle more voltage to your CPU. Like others have said, start with your ram multi low along with your NB multi. When you reach 3.8, bump your NB up to 2600 or so with the volts recommened above and see how that fairs ya in prime95. Ill add a link to an OCing guilde that worked well for me.

Thanks, I'll get started on that.
