TWIN3X4096-1600C7DHXIN and ASUS P5Q3 Deluxe WiFi@n

Heh, here's hoping this is the right place to post this... [edit] Nope, it wasn't. This should probably be moved to warranty questions.

 

I bought the TWIN3X4096-1600C7DHXIN set about a month ago, to replace my previous memory which failed repeatedly. At first it seemed to work alot better, and my system was stable again.

But it didn't really last..

After getting some memory related CTD's and unhandled exceptions in various (visually) high-end games, I decided to run a memtest. At the time, the RAM was manually set to 1333MHz, 6-6-6-20-7-48 timings, with the memory vcore running at 1.80v, and 1.36v NB, FSB strap to NB at 333.

(I posted in the compatibility forum earlier, and that thread led me to those settings to get a stable system.)

 

I let it run overnight, and awoke to find 4 errors. 3 in test #7 on pass 10 and the last one in test #7 on pass 12.

 

After asking around abit and posting on a different site, I decided to test the sticks individually, and this time at Corsair spec configuration, the one stated in the data sheet.

 

To prevent my CPU from overheating, I changed the CPU FSB ratio from 7.0 to 6.0, and upped the FSB to 400, thus enabling me to run the ram at 1600MHz. I also set the timings to 7-7-7-20-7-60 at 1.90v, rest on auto.

 

I am currently in the process of testing the sticks one by one.

The first one is being tested now, and I'll just let it run for about 24h, or until it encounters an error...

 

I will also try each stick in every mobo slot, to try and rule out the possibility that my motherboard is the culprit.

 

Memtest results are fairly consistent, right?

If one of the sticks consequently fails in every slot, its faulty and need to be RMA'd, yes?

 

Any feedback appreciated. (mostly :P)

A: Yes but errors in tests 5-8 would suggest it may not be a failing module.

But if you do find that one is failing in tests 1-4 consistently then I would agree let's get them replaced, please use the On Line RMA Request Form and we will be happy to replace them.

Righto, thanks. :)

Is test #7 the new equivalent of the older #8?

I really suspect my motherboard, although it might just be the timings, im uncertain... The first module has run for 13 passes now, without errors. Im going to run it overnight for 7-8 more hours to be certain.

Its been noted earlier in several posts, and I'm finding it more and more truthful, this mobo just plain doesn't like 2x2gb sticks...

 

Or it might ofcourse be the other module, I'll know tomorrow :)

Ok, I awoke to find about 320 errors in a frozen memtest.

It seems they all appeared in test #7 on pass 36, but since it is frozen, I'm unable to scroll, and thus unable to confirm that they're all from the same test.

 

In any case, I swapped to the other module now, and I'll run it until I encounter errors, or atleast for 12-13 hours.

 

Still, thinking back, I think test #7 is the one that gave errors on my previous memory modules as well...

 

After this test, I'll move on to the other slots on the mobo, while sticking to the same config.

I had (and still have) the following settings while performing the memtests:

The second stick has as of now run 47 passes spanning over 18 hours without errors.

I would assume that it is working properly, but seeing as it is in the same slot and with the same settings as the previous stick, which failed, I am going to run it for another 10 hours or so (overnight, I'm GMT+2).

 

If it still hasn't encountered any errors when I wake up, I will proceed to test the other slots.

I might alter my settings abit to better match up with the ones listed here.

 

UPDATE:

No errors after about 57 passes on stick #2, so I switched to another slot and tested #1 again. No errors, but memtest froze after about 12 hours, 32 passes in.

I'm not sure if thats good or bad...

 

I'm currently testing stick #2 in the second slot. So far so good.

 

2ND UPDATE:

Stick #2 just completed it's 60th pass without errors, I think I can say fairly certainly that it is not faulty...

As for whats happening with stick #1 (the errors and the random memtest freezes) I have no clue.. Could it be that it is just overly sensitive of timings and voltages, and freaks out because of that?

 

Current memtest86+ results:

 

                   Module #1                         Module #2
Slot 1:          -                                     -
Slot 2:   No errors, froze 12h in.           60 passes, no errors.
Slot 3:          -                                     -
Slot 4: 320 errors, pass 36, test #7.     57 passes, no errors.
