Overclocking 1075T, can't reach 4ghz - Page 2

post #11 of 26
Keep your HT @ 2000mhz or lower, the RAM @1600 or lower, the exception is the CPU-NB that one you want it as high as you can but for the moment keep it @ stock (dont know the stock mhz on that one) just till you get a stable overclock, then set your CPU voltage to 1.45 (keep incrasing it till the number on your left is @ 1.45v) then test to see if it is stable. Also check your temps since that cooler might not be able to keep the heat on check @4ghz.

The cooler keeps it very chilly, never gets over 43c while stress testing @3.9ghz. When I chose manual volts and change the number on the right to the normal voltage it wont even boot, it just goes black and the bios says something about overclocking errors and it resets my OC settings. I changed the HT to under 2000mhz and it seems more stable @ 4.0 with stock volts, but crashs when I stress test.

Did you lower the RAM and the CPU-NB?? If not, lower them.
Check on CPU z to confirm the voltage reading, maybe its reading it wrong.

The ram and HT are under their defaults and I'll check the CPU-Z voltage when I get home.

This is really something I don't recommend
the MOSFETs are a 4+1 unheatsinked on old cheap Gigabyte 2007-2008 design with known problems - you are running on it a 125W x6 overclocked and on a tower cooler, ensuring the VRMs get zero cooling and are probably being pushed way too far at this point. You may very well be risking a catastrophic failure by overclocking on this motherboard. I recommend a motherboard switch before proceeding with overclocking.

If you don't understand, you can click the dark red link in my sig for more info on why this is dangerous.

Would some little heatsinks for the mosfets help?
My case temp is only around 30c.

Also, I have 2 120mm fans exhausting at the top, they're basically right on top of the mosfets.

The fans will help but as the mosfets have little surface area the fan probably won't be that effective at cooling them.

It's possible but keep in mind the board still uses the older, cheaper 3-transistor MOSFET design from 2007-2008 (pre "Ultra Durable" era) and if OCP protection is present on the board we don't really know. 4+1 phases, no matter what conditin, are really not very ideal for pushing x6 CPU to the limit anyway. Maybe for the x4, but for an x6 we usually recommend you take the bigger power phase route.
