XMP crash issue

[Spoonii]

Hi all,

 

I built a computer not too long ago and when everything in BIOS was set to auto it ran perfect.

Recently when I enabled XMP the computer would hard lock up with a buzzing sound when playing games, or idle with a game in the background after about 10-15 mins which needed a force power off.

• Nothing else was changed in the BIOS, except enabling XMP to on.
• Later I changed the memory timings to T2 to try and get better stability but it did not help.
• I then reverted everything to BIOS default (Auto everything) and manually set the timings and voltages same as XMP but it did not help.
• I then increased the VCCSA from Auto to 1.15V with manual XMP settings as above and it did not help.
• I then increased the VCCSA from 1.15V to 1.18V it did help, and the system will play about 2-3 hours before a lock up.
• I then increased the VCCSA from 1.18V to 1.2V and it did help, no lock up so far but I am not sure if it is a coincidence or just pot lock.

Using:

• Intel 7920X stock speed, non-delid
• G Skill Trident Z RGB 64GB Kit - F4-3200C14Q2-64GTZR (8*8GB) DDR4 3200MHz CL 14-14-14-34 1.35V
• Rampage 6 Extreme
• EVGA GTX 980
• EVGA Supernova 1200 P2
• Corsair H150i pro (360 rad) in push/pull with 6 fans.

Notes:

• XMP is currently off, but with manual timings and voltage to XMP rated settings.
• CPU temperatures were 55-65 on gaming load.
• GPU temperatures were 75-85 on gaming load.
• Running latest BIOS from Asus website.
• All RAM sticks detected
• Latest drivers for all Mobo components and chipset
• Latest Nvidia Drivers
• Memtestx86 chucked a few errors on the hammer test when i last ran it at 1.18 VCCSA. Did not try again on 1.2V yet.

Is it safe to run the VCCSA at 1.2V as everyday runner?

If it locks up again should I go any higher? and what is the safe upper limit to use for everyday runner?

Should I do something with VCCIO and Vcore?

Should I mess with load line calibration?

Should I do something else to test it?

 

Thanks all.

Thanks all.

Turn XMP off, it causes more problems than it solves.

It is currently turned off, it is on manual timings same as the XMP rated settings and voltage.

Still freezing though.

"when everything in BIOS was set to auto it ran perfect."

 

Put it back to that, leave it be, be happy.

The memory runs 2133MHz when in Auto and that would be poor value proposition as there is a premium on high speed low latency kits.

But I am outside of the window for RMA and I doubt the retailer would authorise it without putting up a huge fight so I can trade down for a lower speed kit.

 

Can I ask for advice with the current speed and timing configs? I feel really bad about spending the extra money not to be able to use it

Well figured it out that but using 14-14-15-35 @ 1.36V & 1.15 VCCSA seems to be stable. Not ideal but close enough.

Thank you to all those who have contributed to helping.

 

Next on the agenda, I have a guest room in the house but seems like it is damp. Might be a leaky roof, don't know where to begin.

Should I try to get an RMA from the estate agent or just not use that room at all and leave it be?
