[UNI] X38 Efficiency: Asus P5E3-Dlx/STT SSD/Cellshocks DDR3

[VictorWang]

have some time to play.
let's show some x38 efficiency
with Supertalent SSD 16G and Cellshocks DDR3-1800 involved

500*7 2000-765-18-1T 32m = 13min10sec, almost beat some 3.6G results


something shocked me is that... my qx68, which can do max-SS-470fsb on other mobo.
boot 500fsb directly and running damn stable. and max-SS-520fsb.
with only vnb=1.57v , vpll=1.84v

[Zeus]

Wow, that's some efficiency!

What chances does one have to hit DDR2000 with such timings and what Vdimm did you use?

[VictorWang]

2.16v vdimm set in bios
to have such a good pair ddr3...might be only 1% chance, lol

[webwilli]

looks very nice VictorWang

i would be very pleased, if you can you tell me some settings that you did in the mainboard bios...

I have the same mainboard and cellshock ddr3-1800 and can´t reach 450 fsb with 1:2 ddr3-1800. My cpu do 530 mhz fsb.

You can use my bios template:

FSB Strap to North Bridge:
PCI-E Frequency:
DRAM Static Read Control:
DRAM Dynamic Write Control:

Ai Clock Twister:
Ai Clock Skew for Channel A:
Ai Clock Skew for Channel B:
Transaction Booster:

CPU PLL Voltage:
FSB Termination Voltage:
North Bridge Voltage:
South Bridge Voltage:
Clock Over-Charging Voltage:

You can use my bios template:

FSB Strap to North Bridge: 266fsb
PCI-E Frequency: 108mhz
DRAM Static Read Control: auto (>1600 should be auto)
DRAM Dynamic Write Control: auto (>1800 should be auto)

Ai Clock Twister: auto (havent studied yet )
Ai Clock Skew for Channel A: auto (havent studied yet )
Ai Clock Skew for Channel B: auto (havent studied yet )
Transaction Booster: auto; enable ,lvl=1 (it's actually tRD=performance lvl)

CPU PLL Voltage: 1.6~1.9v (depends on CPU)
FSB Termination Voltage: 1.4v
North Bridge Voltage: 1.47v~1.57v (x38 is hot, do not set too high unless u wanna hit 600fsb)
South Bridge Voltage: auto
Clock Over-Charging Voltage: 1v

[webwilli]

many thanks

i try your settings later and hope it helps me with my board.

thank you,

and what bios did you use ?

0401 on asus website

0401 on asus website

0504 has cured most, but not all of the 4x1GB memory problems on this board and improved 2x1GB performance also.

i can do this with 2.1v vdimm , (fsb cpu limited in air). but in single channel.

In dual channel in cant boot in 1:2

only 5:8 woks correctly in dual

[webwilli]

i have the same problem Pt1t.

with 1:2 i can´t boot over 435 FSB

[Pt1t]

Same setting as you Victor , vdimm 2.16v , vnb 1.55v

but not blue heatspreader ^^



And 1M 36gp , OS no tweaked.

boot with in 1:2 works now?

[badboy]

I can't even hit 475 mhz fsb. The best I can do is 450mhx fsb with current setup.

[Pt1t]

boot with in 1:2 works now?

yes but you must find the right vNB , between 1.45 & 1.6v

I've hit DDR3-2000 with my P5K3 and Supertalent memory but not with tight timings...best achieved was 8-7-7-20 with 2.1 VDIMM.
