TWINX2048-4000PT - never got them work at stock values!

Hello,

 

Maybe this problem had been discussed before (I passed weeks searchin' the net, and I found a lot of similar problems)n but I need a help here.

 

I bought a pair of TWINX-4000PT a couple of years ago (3 years), to my rig, but I "NEVER" got them to work @ 500Mhz and 1T, not even by doin' a 2.8v and reducing timings.

 

At this time, my rig was doin' fine, I underclocked them to 200Mhz @ 3.4.4.10 @ 1T ... HTT @ 1000Mhz (multiplier X5) ... and Opty 170 @ 2500 Mhz (Multiplier X12.5).

 

I now bought a Vista Ultimate x64, and I'm doin' game development and 3D, ... so, my performances (memory) are no more enough ... and I said to myself that I could re-clock them at 250Mhz; But I remembered that when I bought them, I always had BSODs when they were @ 250Mhz ... at ANY configuration and voltage.

Even by backin' the Opty @ stock 2Ghz, and lettin' the MB decidin' for timings (3.4.4.10 or more) ... weather they are @ 250Mhz, I had BSODs ... even by deleting the 1T (that is a very important thing for me), I still have BSODs, but they are less frequent.

 

I though that they needed some time to be good enough for that clockin', but 3 years weren't enough ... they still BSOD @ 250Mhz.

 

If I put 350€ in memory specifically for its timings, could I ask for it to work at those timings ?

 

Can I ask for RMA ? ... I just need memory to work at its stock timings (250Mhz @ 1T ... I don't care for the rest of timings or voltage).

 

Please help.

Hi,

Sorry for my late answer.

 

Here are my settings (everything not listed = Auto/stock or disabled):

 

Stable (last two years)

Those are PERFECTLY stable settings ... for work purpose.

Cool & Quiet = Activated

Advanced menu:

Ai Oveclocking = Auto

CPU FSB Speed = (Auto = 200Mhz)

SB to NB Freq = Auto

Adjust PCIE Freq = 100

PEG Link Mode = Disabled

 

Over-Voltage X = Disabled

 

DDR VCORE = Auto

FID/VID = Auto

Processor Freq Multiplier = (Auto + C&Q = 5x to 10x)

Processor Voltage = (Auto + C&Q = between 1.14 and 1.39 ... sometimes 1.42)

 

1T/2T mem timing = Forced 1T

 

Memory Configuration:

Memclock Mode = Limit

Memclock Value = 200Mhz

MCT Timing = Auto or Manual for better stable timings

Cas = 3

TRAS = 8 (10 when auto)

TRP = 3 (4 when auto)

TRCD = 3 (4 when auto)

Burst Length = 4 Beats

 

K8 to NB = Auto

K8 to NB = Auto

SB to NB = 5x

SB to NB = 16/16

 

 

Unstable

Cool & Quiet = Deactivated

Advanced menu:

Ai Oveclocking = Manual

CPU FSB Speed = 250Mhz

SB to NB Freq = Auto

Adjust PCIE Freq = 100

PEG Link Mode = Disabled

 

Over-Voltage X = Disabled

 

DDR VCORE = Auto and/or 2.75

FID/VID = Manual for 2.5Ghz, and/or Auto for 2.0Ghz

Processor Freq Multiplier = 10x

Processor Voltage = 1.385

 

1T/2T mem timing = Forced 1T, 2T and/or Auto

 

Memory Configuration:

Memclock Mode = Limit

Memclock Value = 200Mhz

MCT Timing = Auto and/or Manual

Cas = 3

TRAS = 8

TRP = 3

TRCD = 3

Burst Length = 4 Beats

 

K8 to NB = 4x

K8 to NB = 16/16

SB to NB = 4x

SB to NB = 16/16

 

Those settings lead me to BSOD whenever there is a charge on the PC after some to several minutes (Program/drivers installation, 3D rendering test, Benchmark, 3D Games)

When I type the "and/or" in settings, that means I tested multiple configuration there.

 

For system, I've tried from WinXP Pro 32bit SP1 and +, to Vista Ultimate 64bit ... by WinXP Pro 64 and Vista Business 32bit.

All type of drivers, from manufacturers (Asus, MS) to general (nVidia, AMD and so).

 

The system can be functional, but only for desktop tasks and internet surfing (even here, when heavy multiple flash animations load, bamm, BSOD and reboot).

 

I'm working on this PC as secondary rendering/retouching machine, I can't play the installing/uninstalling/reinstalling game, cuz I have licenses for professional software that I need to redo (Adobe CS, Maya, Poser Pro ...).

 

PS: Just a last thing, because this is a work machine, there are no games installed on it, no software besides very important ones (Trend Micro Pro AntiVirus, Microsoft VS2008, 3D professional programs ... and that's it, NOTHING more) ... I only install Benchmark/Game software at OS-transit period, for stability test and drivers selection purpose.

 

Thank you.

 

PS2: Here is attached an Everest pic of problematic settings :

Command Rate should be set to 2T and I would set the memory Voltage to 2.75 Volts and test the modules one at a time with http://www.memtest.org to be sure one is not failing and with most ASUS MB's you will need to disable legacy USB Support when running any memory test but set these settings:

 

Stable (last two years)

Those are PERFECTLY stable settings ... for work purpose.

Cool & Quiet = Disabled especially when over clocking

Advanced menu:

Ai Oveclocking = Manual

CPU FSB Speed = ( 200Mhz) 250 Mhx if run the memory at Full speed

SB to NB Freq = Auto

Adjust PCIE Freq = 100

PEG Link Mode = Disabled

 

Over-Voltage X = Disabled

 

DDR VCORE = 2.75 Min. Max 2.9 Volts

FID/VID = Auto

Processor Freq Multiplier = (Auto + C&Q = 5x to 10x) I would use 7-9 when runnung at 250 MHz

Processor Voltage = (Auto + C&Q = between 1.14 and 1.39 ... sometimes 1.42)

 

1T/2T mem timing = 2T

 

Memory Configuration:

Memclock Mode = Limit

Memclock Value = 200Mhz

MCT Timing = Auto or Manual for better stable timings

Cas = 3

TRAS = 8 (10 I would not use 10 for this part but it may improve performance when over clocking )

TRP = 3 (4 when running 250Mhx )

TRCD = 3 (4 when running 250Mhx)

Burst Length = 4 Beats

 

K8 to NB = Auto

K8 to NB = Auto

SB to NB = 5x

SB to NB = 16/16

 

 

Unstable

Cool & Quiet = Deactivated

Advanced menu:

Ai Oveclocking = Manual

CPU FSB Speed = 200 / 250Mhz

SB to NB Freq = Auto

Adjust PCIE Freq = 100

PEG Link Mode = Disabled

 

Over-Voltage X = Disabled
