Multiplier Question

deathman20 · Nov 15, 2005

Ok saw this over at DFI-Street and someone mentioned it.

Currently im running 9.5x multi with 270Mhz ram. Is running a .5x multi like this not good at all for max preformance? Should I try getting my memory to like 285Mhz and run with a 9x multi?

I have read that the .5 multipliers do not even really exsist. I think CPUZ doesn't even count the .5 it just rounds up or down I cant remember.

Odd I know CPU-Z reconized my clock when I had it @ 8.5x295. But now that I've been thinking of it, looking at someone elses score with close to similar timings, he was getting about 600mb/s faster on the ram.

Would 265Mhz get roughly 6600Mbs in tests then? If so I guess .5 enacts a divider

It was just something I read but I can't find the article. I am still looking though.

The thing with half multies on a64s is that they exist and they work for cpu speed, but RAM speed is a little different. The RAM speed will be calculated using a multiplier rounded up, so at x9.5 and 1:1 RAM speed setting, you'll get a /10 divider on the RAM. meaning that say 250HTT which will result in 2375MHz, will only give you 237.5MHz on the RAM.

That sucks but now I know and will stay with the good multis then.

Thx
