testing rig:
Intel E6850es E0 @ Ultra120
Asus Blitz Extreme, bios=0801
Cellshocks PC3-14400 8-7-6-21 1G*2 @ 8015 2000rpm ram-cooling fan
HIS HD2900XT 512m @ Koolance Watercooling
Topower 2000w Power Supply
Ambient=23c
testing software:
pi_1m
sisoft mem bandwidth
everest mem read test.
[prime95 blend test + Spi_32m] Sync = 1.85G+ mem usage.
testing results:
1) 1.64v 1800 8-7-6-21 stable
2) 1.84v 1800 7-6-5-18 stable
3) 2v 1900 7-6-5-18 stable
4) 2v 2000 8-7-6-21 1T stable
5) 2.14v 2000 7-6-5-18 1T stable
6) more volt. 2.28v 2080 7-6-5-18 1T.
awesome bandwidth at only 3.64Ghz.
2.24v 1800 6-6-5-18 1T stable, that's quite amazing !
same vdimm, 1800 6-5-5-18 1T pi_32m also benchable.
max CL6 memclk arround ddr3-1850
2.26v, 1545 5-5-5-15 1T test, awesome speed and bandwidth !!!
5-5-4-15 also benchable, but a little bit slower than 5-5-5, dont know why.
cpuz validation:
DDR3-2120 7-6-5-18
DDR3-2145 8-8-8-27
CL=9/10 dont scale,
and i've tried flash Cellshocks spd to Supertalent(origin Micron's SPD), but no performance gain.
so DDR3 is still hard to have a conclusion which is good or not.
some is good for CL7, but some is good for higher clk, really really strange.
