1 Real CPU speed? 248/266Mhz on Tue 31 Aug 2010 - 12:19


How to verify the real AK7802 CPU speed?
For my 248Mhz? HPC at even full load Core player shows 220-225Mhz. Resinfo shows only 12Mhz(PLL clock) Smile

Is the 266Mhz versions real?
I have somewhere read that ak7802's cpu frequency can only be = 4 x M / N

M = (62, 63, 64, ..., 94;)
N = (1, 2, 3, ..., 16)

Where m = 62, n = 1 then it is 248mhz
max theoretical: 94*4=376Mhz

So: 266MHz is not possible fake?

Yes, 248Mhz is real but 266Mhz is more like 264Mhz or 268Mhz or just a fake 248Mhz as it is with 64MB RAM.

RAM speed is CPU/2: so 124Mhz and 133Mhz. Max RAM speed (w/o OC) 200Mhz
