Re: TF1230 Design Complete

Yes it slower but. There is a big but. I have real 030 40mhz and what i have squized out from them on aca is 48Mhz and you can forget to start the card above 45mhz with China uknown flying cpu objects. But on TF536 during tests on 50Mhz - no problems. Real 50Mhz CPU's are not cheap today if you find...

Re: TF1230 Design Complete

What can be done is to add a note on the picture itself (card model, clock speed, firmware if known). Everything will be clear by just looking on it.
That can be a main rule to avoid biggest misunderstanding.

Re: TF1230 Design Complete

I gave ACA1233@50Mhz sysinfo picture (11,98 Mips) because there is no official version of that card clocked at 50 Mhz and people just like to compare. Once i tested overclocked TF536@60Mhz(11.95Mips) for around 240h (LW renders). Due to timings i had IDE access problems. Render itself without IDE wa...
