Samsung wonder ram problem

post #1 of 8
Thread Starter 
had something weird happen. Running prime with 90% ram utilized testing my 3570k at 4.7, I let it do its thing, walked away, came back about an hour later and PC was running but would not wake. So I turned it off, rebooted, and got the screen prompting f2 for setup as per as rock z77 itx specs. At this point boot failure occurred and I narrowed boot failure to ram over clock at 2000mhz. now I can no longer over clock at this speed, only up to 1800. Currently running at 1800 mhz speed and 9-9-9-28 1t timings 1.4v and everything seems fine. Did I get some sort of ram degradation?

Two 'random' guesses:

Are you sure that whatever you had at DDR3-2000 was not a blackscreen-crash? What timings and voltage were you running at?

If you're running an ITX board, I assume the case is small too so the inside temps could have gone upwards making DDR3-2000 no longer possible.

Temps in case are very cool in a bitfenix prodigy. I'm watercooled and plenty of air space. Chips are cool to the touch. Was running loose timings at 11-11-11-35 with 1.5v

I'm not sure if you tried or not but maybe clearing your CMOS might help or reflashing the BIOS?

Wondering if the secondary IMC voltages could need a boost for the ram overclock
post #7 of 8
i seam to have a similar issue i cant overclock nothing above stock, it gives me AMD driver stoped responding even at 1866 11-11-11-28 , iam running a low overlock of 4.2 on my 3770k with 1.15vcore
i wonder if vcore voltage this low makes my ram not clock at all frown.gif

Been running at 1866 with 9-9-9-24 1t at 1.45v. Very stable. I've been doing some reading and it looks like some modules need more than 1.5v to hit 2000 and up. I thought I was stable at 2000 with 1.5v, but I guess not. Other than that I'm pretty happy with these results for 24/7 gaming use mainly. I'm getting really good benchmark results too at this speed and really anything more would be placebo.
