F3-16000CL9T + P6X58D Premium

[minuS]

F3-16000CL9T 6GB Trident kit + ASUS P6X58D Premium (BIOS: 0813) + Core i7 930

Random BSODs and Prime95 fails when using XMP settings (RAM at 2006MHz), but all is well when RAM is at 1066MHz.

Help?

Thanks.

Raise QPI/DRAM Voltage until it is stable. It will need roughly 1.30V-1.60V depending on your CPU.

No luck.

XMP puts QPI/DRAM Voltage at 1.4; since updating to 0813 BIOS, Windows won't boot below 1.5; every increment from 1.4 to 1.6 resulted in either reboots, BSOD, or Prime95 errors. Best results seemed to be around 1.58125.

Suggestions?

Thanks again.

Update: System runs perfectly up to DDR3-1600 on "Auto" BIOS settings.

[GSKILL TECH]

Right, as it should be able to auto adjust QPI/DRAM for this frequency. So even 1.60V was unstable at DDR3-2000? Most i7 920 D0's required just about this much, but the i7 930 I've seen lower amounts. Post up the DDR3-2000 settings and I can see if anything is being detected incorrectly.

Thank you

XMP Profile

CPU Ratio Setting: 20.0
BCLK Frequency: 143
PCIE Frequency: 100
DRAM Frequency: DDR3-2006MHz
QPI/DRAM Core Voltage: 1.40 (won't POST, Windows boot issues, or BSOD during Prime95 below 1.5125)
DRAM Bus Voltage: 1.60

DRAM Timing Control

DRAM CAS# Latency: 9 DRAM Clock
DRAM RAS# to CAS# Delay: 9 DRAM Clock
DRAM RAS# PRE Time: 9 DRAM Clock
DRAM RAS# ACT Time: 24 DRAM Clock
DRAM Timing Mode: 3N

All other settings are "Auto".

What were the results with 1.55V+ to the QPI/DRAM Core Voltage?

Thank you

The system was more stable at 1.55~1.60, but Prime95 would still produce errors on various cores after a few minutes.

Test each stick to see if one may be defective.

Thank you

RAM passes memtest without issue at XMP settings; Prime95 fails... Will test each stick individually with Prime95 though.

[minuS]

All sticks pass memtest and Prime95 in singles or pairs using various combinations in various slots... When using all three, however, Prime95 fails.

[GSKILL TECH]

Post pictures of your BIOS. At this point, it just seems like the QPI/DRAM Voltage is not precise.

Thank you

I have yet to take photos of the BIOS settings, though I assure you they're still exactly what I posted earlier; with the exception of the QPI/DRAM Core Voltage being bumped up to 1.60, as per your instruction.

Anyway, I've been conducting some more extensive tests, and I seem to have isolated one bad stick that causes errors in Prime95 after about an hour. I intend to run a few more tests and combinations to confirm, but in the case of one bad stick, what's the RMA process? Do I have to send all three sticks back, or just the faulty one?

[GSKILL TECH]

You can send back just the faulty one.

My RMA paperwork was approved, I shipped the faulty module to G.SKILL, and I received a module in return. I did not, however, receive any kind of confirmation that the faulty module was replaced. When testing the newly-received module, the system crashes as before.

Was my RMA denied, and was the same module returned to me, or is this a replacement module that happens to be faulty as well? How do I find-out what happened? What do I do next?
