I think the 9NDA3 is way underrated in the forums and I've had nothing but good luck with this board. I'm currently running at 9x295 with a Winchester 3000.
That's a 47.5% oc - not bad for a $150 chip. The board is Prime95 stable 12 hrs at that speed and I'm running HT 3x and Memory @ 166MHz setting. For a screenie (1600x1200 image) go
here. Ive had it up to 9x298 and 8x320 and was able to sucessfully complete 3DMark2001.
Tips -
> If your using SATA use the SATA 1 or 2 headers. These are on the nForce3 controller. SATA 3 & 4 are on the Marvell 88SR3020 controller and won't oc worth a s**t.
> Disable Cool’n’Quiet. I use CPUIdle instead and it makes a huge difference in temps when benching (15°C in Prime95).
> For a higher oc Disable AC97 Audio and NV Lan - good for 5 to 7 MHz.
> I'm using DIMMs 1&2 although others have reported better luck with DIMMs 3&4.
> There is a ver 1.1 and a ver 2 board. The 1.1 seems to be limited to Vcore options up to +.20v and the ver 2 goes up to +.35v.
> Use A64 Tweaker. I found out that my OCZ gold rev 3 will run at tRAS 8 since I made the screenie.
> Use the RAM divider settings if you're running the high CPU frequencies. I use the 166 MHz setting and the way it works is that when the CPU is at 200MHz (default) the RAM is at 166MHz but when the CPU is at 195MHz the RAM is at 241MHz. Unlike the Socket A boards the only performance hit you'll suffer is if you can't get close to the max freq that the RAM will do. My OCZ will do 260MHz so if I could run the CPU at 295 and the Mem at 260 I would probably see bandwidth of 75++ instead of the 71++s I'm seeing now.
Hope this helps someone.
