Loosen RAM timings for stable overclock

[CptBarbossa]

So I am overclocking my phenom ii x6 1055t, and I have got it stable(ish) to 3.57 ghz. Ill run prime95 for 5 hours and no problems. I go to play SC2 and the game crashes every time. Also, I can't get my overclock above 3.57 which from what I have read is a little low for these cpu's, though I know that I shouldn't EXPECT higher frequencies.

After going through my system I have basically replaced everything accept for the cheap RAM I got a while ago. I lowered the RAM mulltiplier to 4 from 6.67 so I am running at 1020mhz, which it should be able to handle seeing as how I am running 4 sticks of 1333mhz RAM, still I can't help but think this cheap RAM is holding me back.

I intend to replace the RAM, but until then I was planning on loosening the timing to try and stabilize my overclock. Problem is I am having trouble actually figuring out what I need to set it at. It is currently at 9-9-9-24. I know there is some that involved in finding the right numbers, but I can't find any sort of formula that spells it out.

Anyway, any help with this would be awesome. Thanks.

System Specs:
CPU - Phenom ii x6 1055t
GPU - hd 7970 xfx
PSU - EVGA Supernova 850B2
MOBO - Gigabyte 970A-UDP
RAM - unkown brand 4x2 gig sticks
SSD - 120gb

First to try with things as they are is to raise the DRAM voltage +0.06 and set the CPU/NB voltage to 1.25 and see if that stabilizes

i would go with an 10-10-10-27 and then a minor DRAM voltage increase of 0,02-4V's...

@CptBarbossa,

First off is your 1055T the 95w model or the 125w?

Secondly what are your stress load temperatures?

Just so you know you can run Prime95 for 24hrs and think you're stable, and crash 5 minutes into a game, Why?

Because Prime95, or any stress testing application for that matter does not test graphic or audio load, stress testing is only the first step in your journey to system stability!

Step # 1 is Stress Testing (Is the first tool you use to get you in the stability ballpark)
Step # 2 is Benchmarking (Brings graphic Load Into The Picture and a crash in the benchmark requires an additional increase in Vcore to stabilize)
Step # 3 is Gaming (Brings a full graphics and audio load that the overclock has to support and a crash indicates the Vcore needs an additional bump increase, and when the crashing stops you're pretty much there)

Of course this is assuming you're only multiplier overclocking, and have left your 200mhz base clock or FSB at 200mhz?

I'm going to refer you to Dolk's guide as he does cover the X6 AMD CPU, post what you do not understand, please read all related to your X6 before asking questions, I do suggest reading the entire guide as the AMD BE and the T series are very similar in overclocking, but you can just scroll down to the "Phenom II Thuban Overclocking Section", if you desire.

This is important because you could have BIOS settings holding you back, and you need to discover that.
