Suspect:ram holding back oc due to different sticks :( *please be nice i r noob*

post #1 of 3
Thread Starter 
Ok so first real oc and Im pretty sure I did it all wrong. 20/20 hindsight is all the rage.

cpu-1055t (should have gone black edition as the multiplier is locked at 14. supposedly i can get higher multiplier, but it applies to only 3x cores. i may have to go this direction) 125w. wish i went with the 95

mobo-ga-880ga-ud3h (has newest beta firmware f8i. should i revert back?) http://www.gigabyte.us/products/product-page.aspx?pid=3425#bios
mobo supports 16gb max. should i max it?
Support for DDR3 1866(OC)/1333/1066 MHz memory modules (Note 2)

cooler-Cooler Master's Hyper TX-supposedly insufficient for mult-icore processors. 92" vs 120" ie Cooler Master 212+. Clearly having heat issues however shutting down due to instability and not heat. Max says 62c and hitting 62c+ by +3 to +5 c

Ok here is the biggie
I was uneducated and still am when purchasing ram. Made the mistake not buying pre approved ram by my manufacture for oc. Chose different ram because it was significantly cheaper and the list was short. http://download.gigabyte.ru/memory/mb_memory_ga-880ga-ud3h.pdf
The ram I have is G.Skills F3-12800cl9-2gbrl http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277
I then bought CORSAIR XMS 4GB 240-Pin DDR3 SDRAM DDR3 1333 because it was cheap. http://www.newegg.com/Product/Product.aspx?Item=N82E16820233132

The timings on the g.skills are
9x9x9x25x40 t2 @ 1600
9x9x9x25x34 x @ 1370
8x8x8x22x31 @ 1218
7x7x7x20x27 @ 1066

The timings on the single stick of corsair is
9x9x9x249x34 @ 1332
8x8x8x22x30 @ 1184
6x6x6x16x23 @ 888

Possibly the ram i got is just wacky wack hard to oc/get stable idk http://www.overclock.net/t/1124040/solved-g-skill-f3-12800cl9-2gbnq
I read info that states latency is more important than ocing the ram, but i have read information that says oc ram and lower lat is fine. i know that oc and lowest lat is the best situation.
anyways I am trying to see if i can salvage this solution with the ram I have or i need to dump it and get new ram. If i do get new ram should i be going tripple chan 12gb or do the 16gb max.

I am also thinking about dropping the 1055t and try for a 1090.

Did you get 1 or 2 sticks of the Gskill?

If not, either buy a 4GB kit (2x2Gb) or you need to overclock to the same specs as the lowest performing ram stick.

If you did then just get rid of the Corsair Ram?

Dont get triple channel. Your mobo is only Dual channel. The extra stick would work but in single channel mode and would likely impact ram performance. If you need more than 4GB ram, then get 2x4Gb sticks.

Your overclock may be a little bit limited by the Mobo. Its not a high end overclocking board and only has 4phase power. I would be very careful pushing it too far.

Taking in the generic 1333 CL9 kit with the 1055T was a uhge mistake.
That be it for decent overclocking capabilities, then....

 

To start with mixing generic 1333 CL9 kits with mainstream/performance 1600Mhz @ CL9 kits is already pretty bad because you're mixing RAM that is not rated the same, not binned the same, and not likely to easily work together.  On top of that, your DIMM sizes are different - which will impede on your ability to leverage dual channel bandwidth.  But the biggest blow is the low/lack of IC binning on the 1333 CL9 kit (i.e. inability to clock significantly higher than 1333Mhz, which can be expected on any generic memory kits) may completely hold back CPU overclocking with your 1055T (because RAM speed increases with reference clock - and at the 285-300Mhz bus clock you need to run 4Ghz+ CPU, it is most optimal to be running a DDR3-1600 kit because there is a RAM multiplier [x6.66] that allows the direct operation of RAM at that speed).

 

To get an easier-to-configure and reliable overclock, you will ideally want to replace your single 4GB 1333Mhz DIMM with a 2x2GB DDR3-1600 kit or replace all your RAM with a single 2x4GB kit.  You could also not upgrade your RAM altogether (sticking with the 2x2GB in DDR3-1600 which will give you that flexibility); unless you edit video, compress/decompress extremely large files regularly, or play a few particular games such as BF3, you will not make use of more than 4GB of RAM.  Any of these options will give you the ease and flexibility you need for a good CPU overclock.

There is no triple channel support on AM3 platform.


You should also look into VRM cooling - a necessity for overclocking 125W TDP six-core processors reliably and safely.

 

Your 1055T will be fine for the OC (in that many often get results comparable to 1090T or 1100T overclocks) - but a different board (i.e. non 880G chipset) may give you more ideal ref clock pushing (thus CPU/etc overclocking) results.
