8000UL RMA exchange fails memtest


Entsafter

Recommended Posts

I've received today a new kit Corsair XMS2 8000UL kit.

I tested the computer with dual-prime and I got errors after 15-20 minutes, so I tested each ramstick in every ramslot with memtest 1.65 -> over 1000 error within 30 seconds!

 

I've the latest bios on my ASUS P5B Deluxe and I've set the timings manually -> 5-4-4-9

 

Vdimm: 2.25V

Frequency: from 266-500 MHz (DDR533- DDR1000)

 

Same problems :eek:

 

A friend of mine told me that he had also problems with ram bought in the usa or canada! On the way to switzerland every shippment has to run through a few border controll mechanisms -> maybe the x-ray or other scans destroys the ram modules....

 

The "new" kit I've got, prodocues much more errors in memtest than the kit I've sent to rma -> seems like a complete destruction of the ram...

 

What's going on now? Do I have to send the ram again to the rma departement for approx 15$ shipping costs? And after that I've to wait 2 weeks and will get new, damaged rams?

 

regards

Adrian Schoch from switzerland

Adrian,

The MB you have will not be able to run these modules at these tested settings, from what we have seen this MB will top out about 950-1050 Mhz on the memory. Can you tell me the bios settings you had set for both CPU and memory?

What?

It's not possible to run the specified timings under less frequency? Really crappy... one of the most expensive ramkit won't run on the best 965 chipset board....probably I've to change the ram manufacturer...

I used the following settings:

 

FSB: 266, Ram: 399

FSB: 300, Ram: 450

FSB: 333, Ram: 500

 

I also tested the cpu with lower multipler -> same result.. it's not the cpu, that's for sure ...

Its hit and miss, what are the exact settings you had set and what is the complete system configuration, and it will not matter what memory you use its just may be the top end of your system, but to be sure I would test the modules one at a time to make sure one is not failing.

And have you looked at the performance reports for this MB and these modules?

 

Edit:

I just checked and we have been able to run this MB with these modules at about 1111 Mhz is where they topped out. But I dont have the settings we used at the moment. So please tell me the exact settings you used and we can make some suggestions!

Why do you need my exact settings? I can tell you that I know what I'm doing... other ram modules (other manufacturer) work great with p5b deluxe wifi...

The rams are dead... no way to change this with settings. a big sign is that there were also a lot of errors @ 266 MHz Ram Frequenzy @ 5-4-4-9 and other timings.

No matter which timings/frequenzy -> memtest found thousends of errors....

 

I'm sure that you sent me fully working ram modules, but the border control has something to do with the malfunction -> there are other customers with the same problems with international orders of ramkits...

 

Is it impossible to send the ram to a local distributor?

 

btw: 266 Mhz FSB is top of my system? lol... you must be kidding...the board can take approx 520 Mhz FSB dual-prime stable... the cpu too.... but the ram isn't capable to run @ ultra-low frequenzy with ultra-high latency... 266 Mhz with 5-4-4-9 is really crappy and errors at this speed can only result in bad modules...

Let's get them both replaced. Please use the RMA request found in TSXpress or follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! And please note that you are from the forum!

 

Hmm...

And what do I get when you send me again a ramkit that fails during memtest?

Yes, they're still failing...

But it seems to be a mainboard incompatibilty -> with SPD Timings enabled (very ultra-crapy... 400 Mhz @ 5-5-5-18-22)...

I've paid for 500 MHz @ 5-4-4-9 ... Do I lose my warranty when I change the spd timings with an editor?

And again I would have to ask for the exact settings you have set?

And a link to what you are talking about would be helpfull.

 

CPU Vcore: 1.45-1.65V (phase change cooling)

FSB Termination Voltage: 1.45V

NB Voltage: 1.65V

SB Voltage: 1.7V

Ram Voltage: 2.25V

ICH Voltag: 1.215V (I'm not 100% sure.. but the highest possible)...

PCI-E: 100 Mhz

PCI: 33.33 MHz

 

Ram:

 

CAS Latency: 5

RAS to CAS Read Delay: 4

RAS to CAS Write Delay: 4

RAS Precharge: 4

Precharge Delay: 9

 

Subtiming:

Auto

 

I've also tried 5-5-5-5-9,... till 5-6-6-6-22... no change -> till I tried SPD timings! With SPD Timings I've no problem with stability but with crappy timings...

 

btw: CPU-Z told me that my Max Bandwith is PC2-6400 ...

SPD Timings:

270 Mhz: 4-4-4-13-15

400 Mhz: 5-5-5-18-22

These are the Testing parameters for Twinx/XMS2-8000UL:

 

 

Motherboard make and model: Asus P5WD2 Premium/Deluxe

Each pair is tested and packaged together using the following settings:

AI Over Clock Tuner: Manual

CPU External Frequency: Manually set to 250MHz

DDR2 SDRAM Clock: Manually set to 1000MHz

PCI Express Freq: Auto

PCI Freq: 33.33

CPU Core Voltage: Auto

FSB Termination V: 1.5 Volts

MCH Chiset V: 1.65 Volts

ICH Chiset V: 1.20 Volts

Performance Mode: Standard

DRAM Timing Selectable: Manual

SDRAM CAS Latency: 5T

SDRAM RAS to CAS Delay (tRCD): 4T

SDRAM Row Precharge (tRP): 4T

SDRAM Active to Precharge Delay (tRAS): 9T

SDRAM Write Recovery Time: 5

DDR2 SDRAM Voltage: 2.2

Chipset Core Voltage: Auto

All other settings are motherboard defaults.

 

We use a different MB than what you have and what do you have the CPU and memory frequency set to?
