do i own good ram ?

post #1 of 5
Thread Starter 
well hi this is my ram..is it a good ram or not.Set on 9 9 9 24what voltage(current or default 1.20v).and what command rate should i set it to make it run at 1866 mhz and.....also i hadn't overclocked my cpu...so will it had any effect on overclocking of RAM or not ...Help me to overclock ram[URL=http://www.overclock.net/image/id/1928536/width/600/height/450][IMG]http://www.overclock.net/image/id/1928536/width/600/height/450[/IMG][/URL][URL=http://www.overclock.net/image/id/1928622/width/600/height/450][IMG]http://www.overclock.net/image/id/1928622/width/600/height/450[/IMG][/URL]

I have similar, Corsair Vengeance 2x4, 1600 CL9 Blu.
They don't OC very well, but undervolt like monsters, mine run stable @1.35v (compared to 1.60v used by most others on same freq) @1666Mhz.

It depends on your definition of "Good RAM". It may or may not OC to 1866 NHz. depending on the RAM and your CPU/mobo all playing nice.

If you want to learn how to OC RAM the link below might help. You could start by manually setting the latencies in BIOS to 11-11-11-30 and increasing the RAM voltage to 1.65v.

http://www.hardwaresecrets.com/article/Understanding-RAM-Timings/26

OC'ing the CPU can definitely have an impact on how high you can OC the RAM frequency and vice versa on how high you can OC the CPU clockspeed.

Best system performance is usually obtained by OC'ing the CPU as high as possible and living with the RAM frequency in the default 1333 MHz. range depending on what your hardware will actually allow. Testing of both Intel and AMD desktop systems shows that RAM frequency above ~1333 MHz. does not produce a tangible system performance gain in typical real world applications.

That is actually rather old, and I don't know if it extends to SB or hex Phenoms. It is true for PhII quads and AthII. It is certainly wrong for Llano - it feels best with RAM @1866 and above smile.gif

Thank you. thumb.gif +1 on Rep.

I should have noted that Llano/APUs DO benefit because both the CPU/GPU get access to faster RAM.

X86 CPUs however don't saturate the RAM BUS enough under normal desktop operation to see tangible gains in real apps with faster RAM frequencies above ~1333 MHz. because DDR3 RAM at 1333 MHz. is not a system bottleneck. It's not like 1333 MHz. is an exact number it's just a reference point that is popular for RAM frequencies. For current X86 CPUs there is diminishing PC system gains in real world apps as the frequency increases above ~1333 MHz.

In servers with huge memory banks and heavy loads, yes it is possible that frequencies above 1333 MHz. may show benefit. My comments were specifically in regards to typical desktop use and real world applications where this has been confirmed and thus the reference link.
