[cheapseats]

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.


------------------------------


Vista 64

test basic board stability + vNB


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.


7-7-6-20 / tRFC 60 / 333 strap / clocktwister moderate / tRD 7




7-7-6-20 / tRFC 60 / 333 strap / clocktwister moderate / tRD 7 + CHA pull-in 1+2
(HyperPi 32M vNB = 1.51V set or less)




7-7-6-20 / tRFC 60 / 333 strap / clocktwister strong / tRD 7




7-7-6-20 / tRFC 60 / 333 strap / clocktwister strong / tRD 7 + CHA pull-in 1+2
(HyperPi 32M min vNB = 1.59V set)




7-7-6-20 / tRFC 60 / 266 strap / clocktwister strong / tRD 6

with CL8

8-7-6-21 / tRFC 60 / 200 strap / clocktwister strong / tRD 6
(HyperPi 32M min vNB = 1.59V set)




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

490x9 / 7-7-6-20 / tRFC 60 / 266 strap / clocktwister strong / tRD 6
(SuperPi 32M min vNB = 1.69V set)




495x9 / 7-7-6-20 / tRFC 60 / 266 strap / clocktwister strong / tRD 6
(Everest min vNB = 1.72V set)




495x9 / 7-7-5-20 / tRFC 55 / 266 strap / clocktwister strong / tRD 6





------------------------------


CL7 + CL8 HyperPi / 1:2 CL8 SuperPi 'max' clock / 1:2 CL8 validation

CL7


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)

(NB skew from auto to 300 for POST @ 510fsb/CL8)


515x7.5 / 1:2 / 333 strap / CT moderate / tRD 7 / boot 510fsb




520x7.5 / 1:2 / 333 strap / CT moderate / tRD 7 / boot 510fsb




525x7.5 / 1:2 / 333 strap / CT moderate / tRD 7 / boot 510fsb






533x7.5 / 1:2 / 333 strap / CT Lighter / tRD 8 / boot 525fsb

Loop 25 finished..

verry nice set you got there
just hope you got a longlife batch

[CryptiK]

Great work, thanks for sharing. Very nice SPI32M efficiency too. Have you managed to totally stabilize the ram at 1900 - 2000MHz CL7 or CL8?

[PatRaceTin]

wow long test

[TheKarmakazi]

Great work as always cheap

Loop 25, very cool bug!

thanks zsamz_, all sticks ok so far

thanks CryptiK

only used XP 32 above 475fsb, so i didn't test beyond HPi @ 1000mhz. 500fsb/1:2 pretty good for 32M with this kit, but not worth testing on Vista compared to 475fsb/tRD6 @ 1.5V vNB.

wow long test

i tried to make it short

Great work as always cheap

Loop 25, very cool bug!

cheers mate

the 32M results using a pi_rec from i7. All the other i7 ones i tried, no boost at the end.

Awesome stuff cheapseats - REX is one nice board to play with

[ci2kla]

I FAILED TO DENY THAT YOUA GODLY
GREAT JOB Cheatseats!
How are you manage to boot into windows using such high memory frequency...that's just amazing

[r1rhyder]

OCZ for the win.

[CryptiK]

Cheapseats - after playing with my REX and Corsair 1866C7GTF kit, I have no idea how you managed to pull most of those benches off. You have truly epic skills, and a great board and ram kit. I dont know if its me or my hardware preventing me from replicating your settings.

I will certainly have to reference this thread and spend some time tweaking and learning.

Do you run your NB on water or air? Do you notice any degradation in clocks over time running 1.6 - 1.7V+ through the NB?

[filmbot]

Cheapseats, congrats to you on this achievement, very very hard Also, thanks for the very through post. After I'm done with 2k1 I may throw these back on and see if I can get anything new. I tried when I first got them but was just so frustrated I gave up

Don't worry, you're not the only one. I have had major problems trying to get Elpidas going with REX as has Jody (3oh6). Eva also had a hard time to but he managed to figure it out to point here, http://www.xtremesystems.org/forums/...d.php?t=226580.

Tim, VREF volts is partially key to 2GB Elpida Hyper on REX http://i4memory.com/f83/3x2gb-kingst...3-tests-18365/

[dinos22]

very nice work mate

[denice25]

great job.. keep it up!!

[CryptiK]

What's the situation with the 0403 BIOS? It's not on the asus FTP or the main site. What are the advantages of running 0403 vs 1104 (which I am using now) for example?

Thanks for the link Eva, I have been reading that too since last night for tips. Seems my ram & board are behaving differently to yours though.

[cheapseats]

Really appreciate your comments guys .. sorry to be so late

thanks ci2kla

it gets easier to boot high because RE gets looser and looser past 500fsb/1:2. Bandwidth loss is quite large.

thanks

using Asus air cooler + fan on NB, all the heatpipe etc is still as shipped

0403 + micron worked great for me, and elpida also seems good on 0403 but was the only one i tried. less vcore droop (LLC off) with 0403 than 1001/3 and 1104.

thanks filmbot the main limitations were scaling chipset performance past certain points, but the memory itself ran without problems (as far as tested).
