1075T Overclocking Help!

post #1 of 7
Thread Starter 
Hi all!

This is my first thread on OCN after following this website and learning along the way.
I recently bought a 1075T and tried to OC it to 4.0 ghz, but was unable to do so - thus getting ridiculed by my friend, because he said I should've gotten a 1090T.

my current situation:
I can hit 4.0 ghz, but it cannot be stable.
Right now the CPU is at 3.75 ghz
CPU frequency:250 (max speed that is stable)
Power Boost is disabled
Cool and Quiet is enabled

HT link and NB freq: 2 ghz
memory: 1666 mhz @ 1.6v

NB voltage: 1.2 v
NB PCI V: 1.8 V
CPU NB VID: 1.175 v
CPU V: 1.425 v

I have tried to set the CPU V higher to 1.5
I have increased NB voltage and CPU NB VID voltage to a much larger value (within safe limit): not stable. (I cannot find a definite "max voltage" values for these)

RAM: Kingston hyperX blu 8 gb (2x4)
Mobo: gigabyte 870 UD3
bios: F5a (updated from F4, but didnt improve stability)
PSU: 530 W
Cooler: hyperx 212+

Any ideas as to what I should do? Is the mobo limiting me or do i have to play around with my voltages a bit more? I tried lots of different voltage combinations.

Thank you so much for all your help!!!

Is this a black edition? if it is, start at stock, and slowly bump up the multiplier until a restart/bsod happens during a prime95 test.

it is not a black edition processor; that would be a 1090T

First, forget about the other overclocks. Concentrate on getting the cpu to 4.0Ghz[which is your goal].

The two things you need to adjust are the cpu voltage/cpu clock speed in this case. Do some research around the site. Could I get some clarification on this?

There is a BE version of 1075T too. If you cant get your FSB over 250, there is no way to get 4ghz. Some boards just tank around some FSB.

Perhaps your RAM speed is getting too high
Lower the RAM multi one notch - or you can raise the DRAM voltage some notches and see if it will run overclocked..... it will have to run at either 1830Mhz or 1465Mhz at 275 bus clock though, you might even want to consider pushing to 300 bus clock for exact 1600Mhz RAM operation

Click on my sig. That tune-up will get you to 4.05 stable. I have the same ram & a less capable board. I had to increase ram drive strength for stability but that set up is fast & stable. You can probably do it on less voltage too. I would start where mine's at & back things down from there till you get at the lowest usable voltages.
