Overclocking: Running Memory Asynchronous to CPU

[Jaimie]

What effect does running the memory asynchronous from the CPU have on performance? I would like to continue to raise my over clock, but I am wondering if changing the memory ratio from 1:1 to 5:4 will make the system slower.

I'm running an Athlon 64 2800+ Newcastle, CG revision w/ Corsair XMS 3200C2PL memory at 2.5-3-3-6. My current OC is 9x235, last time I raised it to 9x240 my ram failed.

I have heard that running your DDR asynch to the FSB will result in only a 1-3% performance loss. Since I don't have mush first-hand experience in this, I'll just say it probably won't be too significant, and, if you can o/c the chip enough, the o/c may outweigh the performance deficit of an asynchronous FSB: DRAM ratio. Well, i suppose the best way to find out is to experiment,

Good luck

i run divider without issues, i think there isnt latency loss like usual because a64 doesnt use northbridge for ram, butttttttt without dual channel ram, or a heavy overclock on the HTT, your mem bandwidth will suffer,

It will probably run fine as long as your o/c can keep your RAM almost as fast on 5:4 as it was on 1:1
