Need some advice on my 1055t overclock

post #1 of 6
Thread Starter 
Hi all,

I have been trying for the last couple of weeks to produce a stable system @ 3.5Ghz, 3.8Ghz and 4.0Ghz, each time coming away empty handed. I have tried a multitude of voltage adjustments and different speeds on the NB, different RAM speeds, RAM timings etc.

It's now getting to the point where it seems impossible to overclock my system without some sort of error. I'm fairly sure it is because of my RAM though.
I have 4 2gb DDR3 DIMMs of Elixir (i believe the brand is, that's what it says on the ram itself, i had to pull it out and have a look). The ram is rated to run at 1333Mhz @ 1.5V. I got this ram off a mate and it is a few years old, but it was something that I didn't have to pay for when I built my computer.

Is this RAM the reason I am being held back with my OC? I've tried running it below 1333Mhz, but I still can't achieve a stable system. As far as I know it is some cheap no-name stuff so should I consider upgrading to some proper OC able ram?

If anyone can help me out here I would appreciate it. Thanks.
BTW if I do need new ram (which I probably will) I have a budget of about $60. 8GB of good, solid ram that would enable me to take my 1055t to about 3.8Ghz would be good. Also I did a bit of searching and it seems that 2 dimms are better than 4, so an 8gb kit with 2 dimms @ 4gigs each would be good I think (something that I can OC a bit).

Buy some 1600mhz ram from a decent manufacturer (corsair, kingston, mushkin etc) and see how you get on with them.

Its your ram, I had the same problem. I was only hitting a stable 3.5GHz with my 1333MHz ram, XD advised me that 1333MHz ram is pretty much terrible in terms for overclocking. I upgraded my ram to 1600MHz and i am now easily running my 1055T @ 3.9GHz with Ram running CS6 timings.

Any specific RAM you would recommend me to pick up? I notice you've got some G.Skill RAM in your sig rig. Does that work fine on your AM3 board? I only ask because in the specifications for most of their Ripjaws RAM, G.Skill say that it is designed for sandy bridge or i7 processors.

Moving past 3.5Ghz (250Mhz bus x14 CPU multiplier) is the tough part when working with generic 1333 RAM, due to the low binning that results in the likelihood of the generic RAM being completely unable to OC along with the rest of the system. Therefore, it holds the rest of the system OC back. Because at 4Ghz you require a 286-300 bus clock which ideally works with DDR3-1600 (due to direct speed compatibility using the x5.33 multiplier), it may not be possible at all to reach 4Ghz on DDR3-1333 with a 1055T. That is why I consider DDR3-1600 an absolute minimum for overclocking the 1055T: get DDR3-1600 for the higher binning (allowing for overclocking) and better system response. You *could* try running 333Mhz bus to use the x4 multiplier to get 1333Mhz memory, however most (if not all) boards will not reach 333Mhz bus clock stable.

2x4GB of DDR3-1600 can be found for as low as $40-50 nowadays. That investment will allow you to take your CPU much farther.

Thank you very much xd_1771, I'll look at getting some 1600Mhz RAM then.
