Mr.Scott - SDR SDRAM @ 149.9MHz - 149.9 MHz Memory Frequency

Recommended Posts

Posted (edited)

I'm booting at 110 FSB, so PCI is roughly 38MHz. PCI limit is roughly 44 MHz.

Problem is board gets cranky around 117 FSB. Need to get into the 1/4 divider but I don't think the CPU is up to it on air only.

So yor headroom is 32% of a given strap? I thought my board is a crap (having app.40% of headroom)  but seems like I'm too used to TUSL2.

For this time I'm tested only Asus Cuv4x-e and made 161mhz with SDR. Boot at 120mhz, the rest from windows. Vccio didn't help. For me need another volts on NB.

Was it /4 pci divider action when booting with 120? In other way - are you able to go 161 with +PCI ram?

No, is the /3 divider.  /4 divider don't permit +33mhz of the sdr frequency.
