Samsung 2x4Gb Low Voltage DDR3 1600 kit (OCing to 2400+) Discussion - Page 120

You should easily get 1600mhz with CAS8, but CAS 7 might require some tweaking of the secondary timings and different RAM/IMC voltages. I haven't seen anyone hit CAS6, but Intel platforms generally do better with higher clock speeds and looser timings.

I can do 1600mhz 6-7-6-21-1T at 1.65v...even 1866mhz cl6-7-6-26-1T too, same volts. rolleyes.gif
I'll post some validations later.

Are you using the bios that gigabyte put out just for overclocking Samsung ram?

It's just my particular CPU And board combo that doesn't allow to go high on memory overclocking. I'm just glad to be running 4.7ghz on a relatively low voltage. thumb.gif

3770k's imc is way better than 3570k's...but I need 1.37v for 4.7ghz lol

I'm using f14 bios, same results as special f10x bios, but final release.

Either ASUS Qfan is lazy(showing 1059-1100 rpm on my PH-140s whose PWM max should be 1200, this is on turbo(max) setting) or my R4 2X 140 mm stock intake isn't getting enough air in.

But at 1.304Vcore : Max of 73-80-78-75C in the 12 hour run with Room temp 21-24C while acceptable(max is 25C from Tjmax) it means I don't have thermo headroom for a 4.6-4.7 attempt, Getting 4 140mm T.B Vegas Duos in today along with a pair of TY-143s to see if I can improve the cooling, if that don't help then I'll remount with some PK-1 TIM.

Also trying to see if ASUS fixed the Fan Xpert 2 getting rickrolled by registry cleaner(tune-up utility in my case) issue so I can use it.

Pretty good results! Nice ram chips there...they may have some more ocing headroom, but sometimes it's not worth it.

On a sidenote, I've lowered my vdimm from 1.65v to 1.575v and I'm still stable. 2133mhz cl10-10-11-26-1T (those sort of timings work good for these chips, as do 10-11-11-26-1T, which could also be 9-10-10 or 9-9-10...)
