680i folks tighten those sub timings for 975x chipset like p

System:

Intel Core 2 Extreme X6800 L627A872 B2 Step 6
Swiftech Apogee/Radiical Triple Fan Single Pass Rad/MCP655 + Kayl 100W Custom PSU
Asus 680i Striker Extreme 0402 bios
128MB Gainward FX5200 PCI card
2GB OCZ PC2-8000 Titanium Alpha VX2
4x80GB Hitachi 7K80 SATAII Raid 0 on SATA3 to SATA6 ports
Pioneer DVD Burner
600W OCZ EvoStream

560mhz 4-3-3-4 2T 3-1-3-6-34 at 2.5v vdimm

Yup tight ass main and sub timings on Asus 680i Striker really do make a huge difference. Who would of thought I could pull off sub 13min 30s Super Pi 32M times at 3600mhz with a 680i chipset motherboard without even clocking memory above 560mhz (DDR2-1120) speeds!

Jumped all the way to 560mhz 4-3-3-4 2T with sub timings of 3-1-3-6-34 at 2.5v vdimm bios set. According to memtest86+ v1.70, reported bandwidth at 560mhz 4-3-3-4 2T was 5413MB/s versus at 533mhz 4-3-3-4 2T of 5209MB/s.

Digital camera snapshots of 32M run with 3x cpuz windows open + memset window.

Final result = 13m 28s 391ms

Re-ran 32M but with cpuz and memset windows closed = 13m 27s 719ms !

1M time = 13.922s

Everest Ultimate Bandwidth with 43.3ns latency!

Hexus Pi Fast

All I can say is bloody fast for 680i chipset considering 32M time at 3600mhz is pretty much right up there with 975x chipset as far as i can see

Managed to clock ram up to 600mhz 5-3-3-3 2T but with even further tighten the sub timings even more but had to loosen CAS from 4 to 5 in order to keep vdimm at 2.5v bios set ceiling (within OCZ warrantied max vdimm of 2.52v)

Memtest86+ v1.70 reported bandwidth

@533mhz 4-3-3-4 2T 3-1-3-6-30 at 2.35v vdimm = 5,209MB/s
@560mhz 4-3-3-4 2T 3-1-3-6-34 at 2.5v vdimm = 5,413MB/s
@600mhz 5-3-3-3 2T 2-1-2-8-24 at 2.5v vdimm = 5,625MB/s

600mhz 5-3-3-3 2T 2-1-2-8-24 at 2.5v vdimm

Super Pi 1M

Super Pi 32M

Everest Ultimate Bandwidth with 42.9ns latency!

Hexus Pifast

That's fastest I've managed to run Super Pi 32M at 3600mhz cpu speeds on any core2 platform to date (including Asus P5B Deluxe/P5W DH, Intel D975XBX, DFI ICFX3200) !

Yup further tweaked managed to shave a few seconds off
