Overclocking 1035t?

post #1 of 11
Thread Starter 
Hello,
I was wondering the highest I could overclock an amd phenom ii x6 1035t
with a high level of stability, and preferably not increasing the voltage.
And just how hard it is to overclock on in general...
Thanks!

You can overclock a 1035t, but to do so you would have to increase the front bus speed as opposed to just increasing the multiplier (which is locked at a maximum of 15.5). So compared to something like an i7 2600k, it is a bit more difficult to overclock, but it should be manageable if you have a good enough motherboard and RAM.

Fill out your system specs so I and others can help you with your overclock. Also, you will have to increase the voltage in order to gain a stable overclock, there's no way around it with this particular chip. I have a 1055t and I had to increase the voltage on that.

You're going to have massive problems with that much slow RAM on a 1035T, because they usually can't take high BLCK frequencies, even if you dial the multiplier down. Expect 250-275 maximum, which would give you 3250mhz-3575mhz.

The maximum multiplier is 13, not 15.5. 15.5 is the turbo multiplier.

That's false. Stock voltage is almost always too high, I got 700mhz out of my 1055T on stock voltage.

That board has an 8+1 power phase on it, which is good for overclocking your cpu. First just go into the BIOS and increase the fsb speed. Along with that you will have to increase the cpu/nb voltage and the cpu voltage.

1066Mhz RAM isn't particularly good when it comes to overclocking but nonetheless you should still be able to hit just north of 3GHz on that board. Try and keep the RAM as close to 1066Mhz as you can (use the ram dividers when overclocking - don't set it at auto). Keep the RAM at it's rated voltage and rated timings also, manually configure these in the BIOS. Most of overclocking is just experimentation, so if you can boot up into windows with the settings you have in the bios, run an hour or 2 of prime95 to determine whether or not your adjustment is stable. Once you have reached a point where you are happy with the overclock, run prime95 for longer (24 hours preferably) to see if it is compeltely stable.

Also when overclocking on Phenom II chips, try and keep the HT link speed as close to 2GHz as possible. Increase the northbridge speed as high as you want, but it must be higher than the HT speed, as this aids the stability of the cpu overclock. Good luck!

So, what should I do? Overclock my ram? Would that help at all? I mean, to be perfectly
honest, I only wanted to bump up the speed on my cpu to about 3.2 ghz, I wouldn't need much more.

My bad with the multiplier. You might have to increase the CPU voltage, depending on where you want to overclock too. There's no guarantee that you could run that chip at even 3.4Ghz at stock voltage. I've seen some Thubans that for some reason need crazy amounts of voltage to even hit 3.5Ghz. But OP yes it is a good idea not to increase that after you start not being able to boot or have instability issues, not beforehand. That way you can accurately figure out exactly how much voltage you will need.

Well, you don't need to overclock your RAM, more like underclock it to make it run as close as stock speeds as possible.

For 3200mhz, you'll need to put your HT reference clock to 250, then adjust your RAM frequency back to stock with it's own multiplier, drop the HT-link frequency to 2000 and leave the CPU/NB frequency to 2500.

Those are usually the bad rare ones, on average, a Thuban can hit 3.5ghz at stock voltage or less. I can hit 3445mhz at 1.2v, stock voltage is 1.275v.

But in many cases, 1035Ts seem to be do rather worse. They must be binned much lower.

Awesome, this has been a great help! Thanks to the both of you! This just saved me a ton of money, as the 1090t was a good $60 more... thanks again!

they can't hit 3.5ghz with stock voltages... (like your 1055T it's totally unstable..)
