quick ram question

post #1 of 9
Thread Starter 
Friend of mine just dropped off some spare ram for me to play with, 4x2gb of corsair xms3 cm3x2048-1333c9dhx (1333)
currently running 2x4gb gskill sniper 1333mhz, gskill stuff doesn't seem to have much overclocking headroom, or at least my set. Right now running a 1900fsb and ram at 1333.5. Wanted to know if anyone has any experience trying to overclock the corsair stuff? trying to get past this 4.037ghz wall I'm at right now.
any advice would be appreciated.
Thanks in advance.

I don`t really get the point.
Why should the RAM frequency stop you from reaching higher frequencies?
There is RAM divider (FSB ratio).
So you can control the RAM and the CPU independently. (With limitations)
If you want a 1:1 ratio and have a FSB of e.g. 2000MHz i doubt that it would be possible.
Maybe i got the question/idea wrong. If so pardon me.

right now it's a 10:14 ratio unlinked. I'd like to run it linked in a 5:4 or 3:2 ratio. which either puts the ram at 1240 or 1520mhz. The gskills don't like running anything above 1333mhz.
But I was doing some playing around and I think I'm just at the limit of what the board/chip will do anyway. Got it into windows at 4.1ghz and 1520mhz ram (corsairs) but windows explorer crashed. All other programs worked fine which I found a bit odd. Wouldn't post above that now (used to load in at 4.4ghz). also only could run 2 2x2gb ram sticks on the corsair as the board wouldn't post with all 4 in.

What you could do for the 1520MHz which posted is try to loosen the timings and do some stability testing. You didn`t write about adjusting the voltage of the RAM!
Besides my G.Skill 1333ish RAM works fine up to 1470MHz. (Can`t go higher due FSB wall from my mobo)
But timing and voltage should be inspected now!

a 1333 RAM can not reach 1600 is a joke

sorry didn't go into full detail.
bumped voltage up to 1.72v timings tested were 8-8-8-21, going to do some more toying with it this weekend, ran out of time the other night.
THe gskill stuff though I've been messing with for a while now and no matter what, they really won't go high enough.
I don't know if I've gotten as far as my board is going to go though. but I'll be upgrading to a I7 soon enough so, this is just for fun.

Who exactly said it can`t?

Anyway 1,72v is quite high.
So you could try it with looser timings.
Maybe set it something real loose like 10-10-10-30 to see if it is somehow postable. If that works you can start tighten them. Just for fun
Good luck

Thanks, and I'll give it another go tomorrow after work.
might be going I7 in a few days, so we shall see.

1.72v is fine for your sig, if you can find out your RAM fabricated by 8 layer PCB, 1.72v mean nothing, did you?
