Is there a huge hit in peformance when using a memory divider? I have an Athlon64 2800+ currently running at 1.98 GHz by way of a 220 FSB, no dividers. So far no glitches anywhere but I do get errors in memtest. I'm going to be upping the FSB until it can't go any more but wanted to know if the performance hit from a divider outweighs the extra headroom it may give the overclock?
