Help for overclocking a non-black X6 1055t - Page 2

Anything affordable exists that allows cooling the mosfets, knowing that with the CPU cooler, there isn't much space to place an extra fan.

I'd really like to overclock that CPU.

It's probably easier to just get a new mobo altogether, to be honest with you...

Thanks to all of you.

Ok I will not or overclock that CPU, but it will still be quite good enough for 720p with AA.

Cheers,

What about keeping the Vcore stock to 1.3V. I hear that I can reach 3.5 easily (http://www.xbitlabs.com/articles/cpu...locking_4.html). The power consumption would not be greatly increased, right?

MSI has responded to my overclocking question allowing me to do 15% overclock with their board. Indeed, the board is rated to 140 Watts and the TDP of the 1055t is 125w. Hence the 15%.

Can I overclock without bumping the Vcore? In that case, would the power consumption increase above 140w? Let's take the initial scenario, where I push the FSB to 250, NB and HT are kept to 2000 with a multiplier of 8 and the 1333Hz ram is changed to be 1066Hz (still running at stock speed).

Worth trying?

Yeah it'll bump up power consumption a little bit. 3.5GHz needs a tiny bit over 1.3v depending on your CPU.

Keeping vCore lower or at stock with higher clock speed should at least work as long as you are using a cooler that is blowing onto the mosfets, however keep in mind when the mosfets are rated 125W or 140W, that probably means:
1. without overclocking
2. using the stock cooler, which blows down onto the mosfets as well as the CPU.

With your A50 no air is getting to the mosfets at all, so it may not be as capable as you think; I've warned you more than once. If you come back here explaining that your board caught fire in the middle of a long-term stability test, in no ways can we be blamed or liable for your situation.

Ok. I'll freeze the voltage to stock.

I'll try using a side fan shooting at the mosfet on that Antec 900 case. I will first run stability at 15% so I see it is a least stable and still warranted.

I'll let you know.

I guess it is possible to reach 3.5GHz without virtually increasing consumption.

Here is some information from a post I found:

http://www.primegrid.com/forum_thread.php?id=2718

"At 2800 MHz and default voltage, the system took 194W with Prime95 large FFT stress. By accident when overclocking, I found it worked stably at 3500 MHz at lower voltage, resulting in a lower temperature and power consumption than stock! While I could push further to 4 GHz, the increased voltage resulted in a significant increase in power usage and heat output, so I'm settling on 3500 as a balanced setting for 24/7 running. Checked for stability with copious amounts of Prime95, LinX and memtest86+."

Finally, here is a shot from http://www.behardware.com/articles/7...90t-1055t.html

Attachment 188326

It shows some potential for the X6 family. Some OCN members have also managed to reach up to 3.7 without voltage increase.
