Nforce 2,3,4 Timings - Anand

[Flinx]

In past reviews, memory bandwidth tests established that a tRAS of 10 was optimal for the nForce3 chipset and a tRAS setting of 11 or 12 was generally best for nForce2. In the first memory stress test of a production nForce4 board, tRAS timings were first tested with memtest86, a free diagnostic program with its own boot OS that will boot from either a floppy disk or optical disk. Bandwidth of OCZ PC3200 Platinum Rev. 2, based on Samsung TCCD chips, was measured from tRas 5 to tRAS 11 to determine the best setting.

Memtest86 Bandwidth
DFI nForce4 with Athlon 64 4000+
5 tRAS 2191
6 tRAS 2242
7 tRAS 2242
8 tRAS 2242
9 tRAS 2141
10 tRAS 2141
11 tRAS 2092

The best bandwidth was achieved with this combination of nForce4/4000+/TCCD in the 6 to 8 range, so a mid-value tRAS of 7 was chosen for all tests. It appears that optimal tRAS timings may also be memory dependent on the nForce4, so we recommend a quick series of memtest86 to establish the optimum tRAS timings for other memories.

Yea i read that too. Nice little article.
edit: WOOT i'm a Member!

Current machines running F@H:
Athlons: [64 3500+][64 3000+][2500+][2000+][1.3x1][366]
Pentiums: [X 3.0][P4 2.4x5][P4 1.4]

It's not worth saying unless it takes a really long time to say!<P ID="edit"><FONT SIZE=-1><EM>Edited by apesoccer on 03/01/05 12:27 PM.</EM></FONT></P>
