Hi guys here are some results with RE X48 and 2x2GB OCZ3B2000LV2G


open setup:

Rampage Extreme + 0403 BIOS

2x2GB OCZ3B2000LV2G 7-8-7-20 (3x2GB kit)

E8600 / NH-U12P

RE stock air cooling + fans


BIOS 0403 common settings for all runs:

NB GTL Auto
CPU, NB, DRAM skews Auto
NBDDR/A+B DDR vREF Auto

except > 510fsb / 1:2 : NB skew del 300 (CPU skew del 200) for POST @ 510fsb or higher.

450x9 / 1:2 / 400 strap / CL7 / Clocktwister auto / tRD6 / vNB 1.40 set / vDIMM 1.51 set




475x9 / 1:2 / 400 strap / CL7 / Clocktwister auto / tRD6 / vNB 1.51 set / vDIMM 1.617 set

also same as 333 strap / Clocktwister strong / tRD6

XP32 SP2

Everest / 500fsb / 1:2

all 500fsb result from boot @ 500fsb = lower Read versus boot < 500fsb.

(HyperPi 32M min vNB = 1.59V set)




CL7 booting < 500fsb
so far, 490fsb is ~ maximum for 32M with 2x2 + 'full' bandwidth.

500x9 / 1:2 / 333 strap / CT strong / tRD 7 + CHA pull-in 1+2 / boot 500fsb




5:8 shows lower limit for tRD 8 with 2x2GB than 2x1GB, 575-580fsb/5:8 is the max so far with 2x2.

600x7.5 / 5:8 / 333 strap / CT moderate / tRD 9





CL8 - booting > 500fsb for stability (+ low bandwidth)
