So, you can add another gigabyte success story to perc phenomenon.

Which BIOS revision are you using? it seems like a lot of the issues are BIOS related, maybe we can get a consensus on a BIOS that works for Gigabyte boards

I am using the latest for that board, which is F6.

I thought, that when I'll move my system to hardware raid + cache - and I don't work with many large files - only system + 5-50 MB of my files - I thought that it will fit in cache - and whole system will be very fast ...
according to this post - bigger Cache Flush Interval - it is the way to improve read/write performance

Agreed, and it makes a huge difference.

Does anyone know what the max allowable value for NTFS is? On EXT4 according to devsk 30 seconds matches the dirty expiry... But I am not sure what the equivalent for NTFS is, so i used a conservative 15 seconds.

According to a server build log I found on google, they set the cache flush interval to 60 seconds... But that seems really high. Other stuff I have seen says for NTFS you shouldnt go over 10 seconds. Anyone have any input on this?

you can set it max to 255
CacheFlushInterval: Cache flush interval in seconds. Values: 0 to 255.

haha... I should have said "the max allowable SAFE value"... one that doesnt cause data corruption

I know but if your system is stable - and you have UPS ... you can set even 255
I think card will flush cache automatically for new files, right ?

I have UPS, but the stability thing is questionable... I have crashed a few times while gaming. Kinda makes me want to move these drives to a dedicated server...

I would say set this parameter carefully with your setup. Do not run this without BBU if you are anywhere near serious about data loss.

Since its just one command, try various values. Run your favorite benchmark, set another value, reboot and run it again. Rinse and repeat. I am pretty sure that depending on your setup (which means, RAM, mobo, CPU speed, PCIx speed, and the particular implementation of these), you will find no gain after a point. So, DJZeratul, your sweet spot may be below 15 seconds.

This value can be set larger with 512MB cache module vs. 256Mb cache module on your card. So, there you have it: one advantage of 512MB module....;-)
