Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

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

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) !

Damn impressive with the sub-13-30 mate especially with cpu-z open, I'd be willing to bet that without cpu-z open you could take a couple of seconds off that time too. Easily one of the best tweaked striker setups around - no joke.

Yup further tweaked managed to shave a few seconds off

now thats quick, quicker than any 975 I've seen at same CPU speed.

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Yeah very fast indeed

4000Mhz - 10x400FSB / 3950mhz - 10x395FSB


The Asus 680i Striker Extreme just runs my X6800 hotter than on Asus P5B Deluxe at higher vcore settings ~10-13C hotter at idle.

I tried X6800 @10x400FSB = 4000Mhz at 1.56-1.62v vcore and idle coretemp reported 57-67C versus same X6800 on Asus P5B Deluxe at 4092mhz at 1.65v vcore only reporting coretemps idle at 45-47C.

So only could manage 1M times for X6800 @4000mhz at 1.6v (1.57v load) on Asus 680i Striker Extreme. Higher vcore just meant reboots in windows under load (maybe vdroop too much at higher vcore like on P5B Deluxe ? )

Everest Bandwidth with 42.7ns latency


But at much lower vcore of 1.56v idle/1.54v load, coretemp reports more reasonable idle temps and I can manage 3967-3972mhz at 1.56v idle for 32M with lower mem clocks but once hit 600mhz 5-3-3-x timings seems tight sub timings cause instability until I drop cpu down to 3950mhz at 1.57v idle!

@592.5mhz 5-3-3-5 3-1-6-8-28 2T timings at 2.5v vdimm bios set, Memtest86+ v1.70 reports 5540MB/s memory bandwidth.

Compared to my old previous max 32M on Asus 680i Striker

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

520mhz 4-3-3-4 2-1-2-6-20 2T at 2.3v


Now to look for a compromise between max memory clocks with high vdimm and more reasonable lower vdimm and suitable memory clocks which have very tight sub timings.

I ended up with 520mhz 4-3-3-4 2-1-2-6-20 2T at 2.3v vdimm bios set. Only ~1.39 seconds slower in 32M Super Pi than 533mhz 4-3-3-4 3-1-3-6-30 2T at 2.35v run but uses 0.05 vdimm less! Interestingly, 520mhz run was faster in 1M Super Pi due to tighter sub timings at 13.938s (520mhz) vs 13.969s (533mhz).

runs cool thanks to 3x 60mmx25mm sunon 23.5cfm Maglev fans cooling the memory
