Northwood 1.6A on Abit Th7II-RAID

[LATech]

Just set up and running @ stock voltage and HSF:

OS: Win XP Pro
MB: Abit Th7II-RAID
CPU: 1.6A 512/400/1.5V
SL668 MALAY
L149A544-0837
RAM: Kingston 512MB RDRAM PC800 ECC

FSB is 133Mhz and RDRAM Frequency is 133*3=399. PCI and AGP are fixed @ 33 and 66. It can not boot up if using RDRAM @ 133*4. I
think the reason is those RDRAMs were produced more than one year ago!

I will test the stability and post the result up.

LATech,

Even RDRAMs produced a year ago will go much higher than 399MHz....

The TH7-II uses 400MHz clock generators for the RDRAM. About 33-40% of the people with the board can do 533FSB, or very close to it, but the rest with the board can't for some reason. People have replaced their TH7-II board with another, and using the same memory, have hit much higher FSB (even though both boards use the same clock generators). This is what I've observed from reading through the TH7-II threads on hardforum.com.

Note there is an newer, unofficial bios offered in the Strictly Intel area of Hardforum.com that you may want to get, as it enhances the available dividers. It's possible you could go higher with the new bios.

KenAF:

Thanks for your suggestion. I saw you help a lot of people and post some valuable information regarding Rambus clock generator problem. I
really appreciate. After I change Kingston PC800 ECC RIMM (128*4) to Samsung PC800 Non-ECC RIMM (256*2), the system does boot into
Win Xp with 133*4 FSB and 133*4 RAM frequency.

However, I am still testing the stability, but i am pretty sure the RDRAM plays an very important role here.
