OC my 3800+

im not changing my multiplier; only the fsb. So...
my ram runs at 2-3-2-5 at 200mhz, if I were to bring it to 220mhz I would need to change cas to 2.5. Is the change worth it for the higher fsb but slower cas?
My ram stays stable on 2 cas and 210mhz, at 220 it craps out

BM your PC at stock and then at your overclock and compare... tehn you will know...
I am using an Opteron 175 at 2.64GHz using timings of 2.5-3-3-8 running memory at 240x11 also with a 5x HT of 1200MHz and stable doing 24/7 operation.

my HTT on my mobo has setting like 200mhz to 1ghz, no multiplier so I leave it at auto. I guess 2-3-2-5 timings for ram is very good.

Set the HTT to 4x; on most boards the HTT won't go much over 1GHz (DDR). If you want to keep your existing memory timings, then use a memory divider and set the RAM to like DDR333.

yeah i can see its not worth it at those timings. i may just put cas to 2.5 and oc it to 2.6ghz

I'd set the memory at like DDR333 so that even when you raise the FSB, the RAM is still running within specification. Or you could see how high you can raise the FSB while still keeping the standard timings.

10mhz...

i checked with cpu-z my htt speed is 220 but my fsb is 170? or am i reading something wrong? this is oc to 2.5ghz
