Overclock ram not working

post #1 of 8
Thread Starter 
Just built my first AMD for gaming, Loving it! (was always intel before)

Anyways, I'm trying to overclock my ram to its built in profile, and it keeps saying overclocking failed when it reboots. Im new to overclocking so I have No idea what I'm doing wrong.

The Ram i got below:
CORSAIR DOMINATOR GT 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Desktop Memory Model CMT4GX3M2A2000C8

trying to overclock it to 8-9-8-24 2000mhz 1.65 which is whats on its profile.

The Mobo I have, only supports even voltage so it sets it to 1.66, I hope that isn't the difference.

ASUS M4N98TD EVO AM3 NVIDIA nForce 980a SLI ATX AMD Motherboard


also wouldn't mind overclocking the processor too.
AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz Socket AM3 125W Six-Core Desktop Processor HDT90ZFBGRBOX

any ideas or recommendations would be greatly appreciated for this OCing newb

What freq and timings does it run at stock? OC failed usually is only showed for CPU OC failing, RAM usually just BSODs..

it looks like runs at 8-9-8-24 1333 from the MB seeing it.

i did some playing around it looks when I set it 2000mhz profile, it increase the bus from 200mhz to 250mhz, setting it back down to 200mhz the computer boots up, but the ram is running 1600 now.. hope that heps

The increase in the bus is the reason of the OC failed message. That's strange, however. I'm pretty sure it's not supposed to happen Why don't you keep running it @1600 or 1333 and just brutally lower the timings? This should perform about the same, and have a problem-free boot give it a try

dixson: He/she has told us already. ASUS, nVidia chipset motherboard.

Usually it's the 800 series chipsets that allow you to push RAM to 2000Mhz with an x6 (motherboard actually plays a small part in RAM overclockability, since it hosts the actual link between CPU and RAM). The very first thing you'd have to do is raise the ref. clock, you need at least 250Mhz ref. clock to reach 2000Mhz via the x8 multiplier. All other multipliers should be lowered (unless you're overclocking that as well, but take it one at a time). 1.66V is not a huge difference, it is not a problem.

I can't seem to push the FSB, only seems to boot up @ 240fbs or 280fbs but is unstable. Not sure what to do to increase stability. I actually lower the CPU multiplier from 16to13 (to keep the clock speed about the same) and it makes no difference.
Would like to find out what I need to do to make it more stable..

On a side note, I got the system stable with a 18x Cpu multiplier w/ DDR3 Ram@ 1600mhz 7-8-7-20-28 don't know if its better to have faster ram, or faster timing, would like to know. (No FSB overclock though)

1600 CAS6-7 should about equal 2000 CAS9-10 while being easier to stabilize.
