Asus X58 + 6/12GB memory overclocking - detecting less memory than installed

disable XMP profile and set memory manually try 9-9-9-24 2T tRFC 110 with vdimm 1.64v or 1.66v and then try different QPI/DRAM values between 1.25v to 1.45v and see

Thanks for the reply !

That's what I set in my Bios

Ai Overclock Tuner - Manual

Dram Timing Control

Dram CAS Latency - 9 Dram clock
Dram Ras ........ - 9 Dram clock
Dram Ras ........ - 9 Dram clock
Dram Ras ........ - 24 Dram clock

Dram Timing Mode - 2N (I don't have 2T :s)

Dram Bus Voltage - 1.64V (I also test 1.65V)
QPI/Dram - 1.25V (I also test 1.45V and 1.35V)
RFC ?

PS: Before I had 12800CL9D-F3-4GBNQ and it worked very well even though I took advantage of the Tri-Channel but after the updated bios (1504 to 1639) slot B1 do more work. I went back to old Version Bios but it did nothing :s.

from here Asus P6T6 WS Revolution Bios Screen Shots

TRFC = DRAM REF Cycle Time

It's good but still 4088MB detected

. In Dram Timing Mode, I have : AUTO, 1N, 2N, 3N and not 2T. This can be a problem?

2N = 1T
1N = 1T

no difference just terminology.

If you have other memory or motherboard, you should test in them to confirm it ain't a board/memory issue.

Also try loosen (higher) tFAW value - in above bios screen that is DRAM Four Act Win Time = tFAW set to sat between 31 and 39 and see

I did as you wrote above, but still the same problem.

Thank you anyway for all this so far but if you happen to solve my problem I will know very grateful !

Edit:

I test it :

Edit²:

I tested 31 to 39, but still nothing.

Edit: (again

)

I restart Memtest86 and it still detects only 2 strips of 3 but I saw it at the end !

- Slot 0 : 2048 MB PC3-10600 - G.Skill Intl F3-12800CL9-2GBNQ *XMP*

- Slot 1 : 2048 MB PC3-10600 - G.Skill Intl F3-12800CL9-2GBNQ *XMP*

I have put Manual not XMP in Bios

Résultat de Memtest86+ V4.00 :

3 pass and 0 errors

Acide-Burn · 31-12-2009, 08:03 PM

What can I do now?

eva2000 · 31-12-2009, 08:16 PM

yeah memtest reports XMP support not operation so no worries.

I'd probably rma the memory and try a different set of memory
