Hi, everybody

I am having some issues with my corsair vengeance 8GB(2x4GB) running in 1600 mode, i have changed the multiplier to 1:4 and adjusted the memory timings to 9-9-9-24 @2T but my machine restarts, i have tried to up the ram voltage to 1.65v and NBVID too but cannot get it stable, i have not overclocked my CPU x6 1055T 133W, but only trying to overclock my ram to oc recommendation. Can somebody please point me into the correct direction thanks in advance.


Win 7 x64 Ultimate
AMD Phenom II 1055T stock 2.8ghz
AMD Radeon 6870 1GB
8GB Corsair Vengeance DDR3 stock 1333 9-9-9-24 1T

overclock 1055T use FSB so .. if you can raise fsb and the ram will auto incrase too. first try ran your RAM at 1333 in 3.6 Ghz your RAM will get 1600 @800 with lower timming 10-11-11-40

how the height of the CPU voltage? because dangerous if mecapai 70C, then you should do that by trying to raise the FSB step by step and always do a test to determine the height of the temperature. think say 3.5GHz Zalman will be able to do that because the CPU voltage ranges only between 1.32 - 1.36v depending on hardware capabilities.

I have managed to get it clocked to 3.5ghz but at 1333 mem speed, @3.6ghz it surpasses 70degrees when under full load (p95) but room temperature was about 22degrees, if i triy to adjust mem fsb to 1600 it is not stable, windows restarts.

yeach your RAm not strong .. drop ratio, look at CPU-Z in table jedec, compare speed 1600/1333/1066 it will little different speed , not too much.
I have 1055T and my ram default 1333, overclock at 3.8Ghz and RAm at 3:8 (@725) it's enough speed for every day

how much did u up the voltage to get it too 3.8?

I'm confused, is your memory 1333mhz or 1600mhz rated?
January 14, 2012 1:45:04 PM

sorry its rated at 1333 but is overclockable to 1600 corsair vengeance

What makes you think you can run cas 9 1333 1.5v memory at cas 9 1600 1.65v? Of course it's going to fail...

What is the model number of the kit you have?

You just told me in your last post it was 1333.....I don't know how anyone can help you when you keep giving us incorrect information.

I think you should be happy at 1333mhz/8-8-8-20/1.5v
