Is this normal...

post #1 of 4
Thread Starter 
Ok well working on a new OC and so far i just have the fsb @ 225, and multiplier at 17.0, stock. All is fine and stable, but about the ram, it's originally 4gb ddr 3 1600, but in the bios now it shows x6.66 memory clock @ 1499mhz. When i set it to 8.0 it turns out to be 1800mhz. Is this because i oc'd the fsb making the ram oc'd as well? When i hit the wall for increasing fsb is tha because teh ram can't go higher? Also, should i leave it on 6.66x or put it on 8.0x?

If your RAM can handle the 1800mhz, you can leave it there. However, if you want to continue increasing your FSB, you may want to drop it to the x6.66 multiplier in order to insure that your CPU is completely stable.

Question: Is there any particular reason as to why you are using the FSB instead of just multipliers?

Well, i heard using the fsb versus the multiplier results in a better boost because fsb increases everything, in contrast to just using the multiplier, also if the ram is advertised as ddr3 1600, how is it possible that it could handle 1800mhz? Right now my memory is @ 834mhz(1668) haven't tested it so i'm thinking it will crash, but it posts into windows

edit: fsb @ 250, mult @ 17, nb @ stock(for now)

Could be because it's set at very loose timings. What make/model? Test the RAM for stability.
I'd set the multiplier back to x6.66 though and mess with it only after finding the CPU/CPU-NB/HT ceilings. Reference clock affects pretty much every other speed (CPU, CPU-NB, HT, RAM).
