Samsung 30nm OC help needed please!

post #1 of 4
Thread Starter 
Hi all,

Hey, I would really appreciate some advice about stabilizing my Samsung RAM overclock. I'm currently trying to run it at 2133 MHz with 10-10-10-28-1T timings, with the VCCIO/IA set to 1.125 and the RAM voltage at 1.55v. However, upon running a Prime95 Blend test with all RAM used, I get a rounding error within 20 seconds. Do you have any advice, or a pointer to a thread that could help? I've already looked in the thread in Online Deals, but I didn't see any advice or anything to try.

I'd say bump up vcore.or LLC...other settings look OK to me..I have same RAM..eh.If you're only running 2 sticks..1.12 should be fine..try 1.13 and 1-2 vcore bumps

Try running it at 10-11-11-28-1T 1.50v. It runs rock solid there and is a good place to start tuning it in to fit your system.

I got 10-10-10-28 1T pretty easily with 1.406v and 1.100v VCCIO.

But that's where my VCCIO was already set and I haven't tried for more than 2133MHz on the Samsungs.
