6400 c3 xms2 dominator and 680i; Advice please?

[furiazoli]

Hello guys.

So i have abit in 32 max , and bought some 6400 c3 dominator (6403 :biggrin: )

put (2.4 V manual 3 4 4 9)

i soon as i bought them i run memtest for 30 h no errors at all :) i was happy;

For two months system was running without blue screen without any error messages had some minor errors but were software based.

so i leave my pc on (idle) after a day i came home black screen.

Rebooted, bios booted, could see the detection of the cpu, but system fried when tried to detect memory size and timing.

Rebooted again black screen error code c1;

 

So i've removed both memory modules,cleared bios leaved the pc unplug for several hours; put battery back pluged in booted without memory; error cod A0 and beeps (that's ok no memory installed);

 

put one memory bank in c1 post error code; :[pouts:

 

Now comes the funny part :biggrin: removed the first memory bank; and put in the other one, A0 error code but WITHOUT BEEPS :[pouts:

i tried to switch them in different ways nothing; so i got some 8500c5 from a fried it booted without problems; tried to boot with combined memory modules;

nothing they just dont want to boot;

 

i tried with several manufacturer rams even with kingmax :biggrin: they all booted

 

now something interesting a friend tried the memory on tree diferrent motherboard and on a 975 platform they booted, and the other two no, and tested them for 1 day without problems on the 975 :o:

 

Should i RMA the memory modules?

Now i read some other forums it seems that many other users had similar problems but after a while the new memory behaves like the old ones; one guy had changed his memory 5 times (they all have 680 i :confused: );

another one sad the memory live is from one hour to 6 months on a 680i based platforms (i dont want to believe this )

 

if I RMA the memory should i run them on 2.1 V ,4.4.4.12 or should i leave them on standard jedec(cause im pretty sure leaving them on 2.4 will burn them out again ) ?

 

There is another rumor ; they say that in time the ram characteristics is changing so it will not boot anymore on 1.8v, but plugin in another memory module (new) and setting it to 2.4 v and removing the new one with the old ones, will make the pc boot; i couldn't check this because i dont have 2.4V memory module; What do you think about this ? could be true ? there were some users that are using this trick on 680 i :sigh!:

 

Any advice is welcomed :):

If the modules are working in another MB, that would suggest there might be some problem with your system, and as long as you do not go over 2.4 Volts if they ever fail we will replace them. In addition, are you using the memory fan for these modules? If not I would suggest getting one.

[furiazoli]

Tanks for the reply Ram guy.

Of course that i used the memory fan provided because i know that 2.4v is pretty high even for d9 chips.

2.6 is max i think. correct me if i'm wrong.

System is okay, i booted it up with several ram's and had no problem at all. its past a week since i'm using different ram to work on my pc and didnt get any error (blue screen, memtest, or fatal) so i'm pretty sure its not the system.

I reflashed the bios several times,with different versions, no effect, the corsairs didnt wanted to boot again same errors (a0 on one stick c1 on the other)

 

Before i heard that they booted on a 975 platform i thought they were damaged by electromigration.

 

so the ram booted without problems on a 975 and via p890

NOt booted on any 680i platforms (different manufactures)

that's strange; and confusing; Any idea whats happening?

I send them to RMA;

 

Question,When the new ones arrive(hopefully), should i run them at a lower timing such 2.1-2.2V 4.4.4.12 or should i leave them on standard JEdec

because 2.4 V i know for sure will kill them and i'm happy to loose speed for reliability?

 

Note:for what i have read, pushing d9 chips above 2.0 V will make them suffer from electromigration. correct?

If the modules are functioning properly in a different system then there is something with your individual system configuration that is causing the issue. These modules have been tested on many different 680i motherboards so we know that they are in fact compatible. If both modules are exhibiting the same behavior, there is probably another cause, than the memory itself. It would be unlikely that both modules would become faulty at the same time, and cause the same issues.

[furiazoli]

Hmmm maybe;

Now its a little late for do more testing i already sent them to rma;

 

 

They worked perfectly on another system more exacly for 24 h without any error at all(both sticks).

On a 975 and on a via 980 they booted;all was fine; no errors;

on a 965 NO BOoT AT ALL

on 680I's different manufacters(abit,asus) NO BOoT AT ALL.

 

So there is something fishy with them thats why i sent them.

 

MY Question is, if they are replaced,should i run them at a lower timing such 2.1-2.2V 4.4.4.12 or should i leave them on standard JEdec

because 2.4 V i know for sure will kill them and i'm happy to loose speed for reliability?

 

Because this is my second pair of high tech ram that seem to burns out;

 

Note:for what i have read, pushing d9 chips above 2.0 V will make them suffer from electromigration. correct?

These modules are tested to run stably at 2.4v and we have a few other parts that are designed to run at 2.4v. If there was an issue where this memory was failing because of being overvolted we would surely know by now. The memory that you have runs at very aggressive timings and some system configurations may have issues running at those settings. I can assure you that if the modules are functioning properly on a separate system, then there was something wrong with the way your system was configured. Memory failure is not intermittent, memory either works or it doesn't. You may run them at a lower voltage if you like, however we can only guarantee that they would be stable at 2.4 volts, because that is what they are tested at.
