X6 1055t overclocking problem

post #1 of 3
Thread Starter 
I am trying to get past 3.5GHz. So far everything has worked perfectly for me, but if I try to push it forward even slightly, I get a boot failure and have to manually reset CMOS.

Here are my specs:
MB: Gigabyte MA770T-UD3 (Latest BIOS)
CPU: AMD Phenom II X6 1055t @ 3.5GHz with stock cooler at the moment
Memory: Corsair desktop memory 2x2GB DDR3 1333MHz (might be the problem causer) It is very basic memory. Even passive cooling isn't included, just big Corsair stickers on the sides.

Here are my BIOS settings:


Memory timings and voltage are manually set to their default settings of 9-9-9-24 and 1.5V. AMD CnQ is disabled and so is C1E Support. Temperature is normal. I've tried to set the memory multiplier to its lowest, but it still fails to boot and it's the same story with every other setting whenever I try to change those. I've also tried increasing the CPU voltage, doesn't work either.

Any ideas/suggestions?

Looks like your memory has the batch of "non overclocking" ICs.

I've seen this before. The binning is so low, that the memory does not budge at all past 1333Mhz or run at any lower timings. This is usually found only on (lowest binned) generic 1333 CL9 kits - which is a bad idea for a 1055T. 3.5Ghz is pretty much your max overclock as a result. You've been held back by poor RAM.

Consider DDR3-1600 a MINIMUM for Phenom II 1055T overclocking - and for that matter, any locked multi Phenom II processors with an x14 multiplier. Get it cheap while you can.
