does increasing vdimm help stability??

post #1 of 12
Thread Starter 
ok when i started OCing ran into stability issues at low speeds, and pumped up the vcore to fix it, then someone suggested that i lower vcore a tad a raise the vdimm. it worked for me, so when others find that their unstable, i let them know that raising vdimm to 2.7-2.8v should help. but i've been met with a surprising amout of resistance on the forums. most others say to dissreguard what i've said, and that it wont help, this has happened a number of times. so i want the official thoughts from these forums, so i can know once and for all what is right. because i dont want to be spreading false rummors that it works if it doesn't, and also i dont want to not tell people if it does work. so start posting guys, i want to know what you ALL think of this one.

They way I see it, if your memory passes memtest then its stable. So just pumping more juice to it seems like a wasted effort.

It depends...ram like tccd dont need much more than 2.8-2.9 to reach a very high fsb and keep decent timings. Ram like bh-5 needs a high voltage (3.2-3.5) to get a high fsb with tight timings. Just depends on what ram your using. In lonnies case yes pumping more vdimm through stable ram is pointless.

what if the ram is causing the instability?

loosen up the timings... or run a devider to take less pressure off of your memory.

this is it? so the official consensus is that it might or might not affect stability? we need more feedback.

Are you using 3 x 256 modules b4ecause that could be the cause.
Also, some boards aren't friendly with RAM that has chips on both sides.

its not a specific question, im saying in general does raising vdimm help stability (im stable, its so i dont tell others the wrong thing)

I dont get it. Yes it helps if your ram is causeing your instability and needs more voltage. there is no in generel cause all ram is different and you cant generalize it and say yes raising ram causes your system to be more stable.

There will be instances where raising the voltages of your RAM will increase the stability of your system.

But as steveo said, you cannot generalize it because it's not going to be the same thing causing a weak link everytime. If you have your timings too tight or have the FSB on it too high and not enough voltage going to it, yes it can cause instability.
