Of course not its fine. I run upto 1.95v+ Cl12-12-12- 4000+mhz often.

For 24-7 1.5v is fine on Samsung IC. Heat spreaders are also only for looks no cooling is needed.

CPUZ when trying to read registers already in use by other software or apps can indeed cause this problem. TurboV by ASUS and CPUZ running at the same time for example is immediate reboot with certain version of TurboV.

Check one stick at a time 2133 first with CPU at stock.

Having applications polling the CPU will help instigate any instability. So it's not so much that it was CPUz making the system unstable, the system likely is just unstable. Make sure to test the memory with the appropriate methods (HCI, GSAT)

I should have clarified, the memory has passed 8 hours memtest and a few runs of HCI at 2133, but as 8 pack mentioned I was running CPU-Z and HWINFO on every crash. As soon as I stopped using both it has been fine.

I've now validated each stick at 2133 and an HCI run at 2666 CL14 with no issues. The moment I try anything beyond 2666 I get random boot loops and instant HCI errors regardless of latencies and voltages. I'm going to swap them with the set in the other machine in order to narrow it down to the memory kit itself or the CPU/mobo.

That's the best way. Initially running one stick at once xmp with cpu stock core frequency.

zola25 · 7 Aug 2017 at 18:51

^ Thanks 8 Pack, it seems one of the modules is faulty. It will not run at > 2666 without boot loops and HCI memtest errors in either machine. The remaining stick from the kit, plus the two in the other kit work fine at XMP speeds in both machines. I presume the best course of action is to post in CS and initiate an RMA.

8 Pack · 8 Aug 2017 at 19:27

Yes do exactly that. This far RMA rare is under 1% so your very unlucky. Sorry about this we will get it changed out for you asap.

zola25 · 8 Aug 2017 at 19:38

^These things happen

. I've got an RMA open now, cheers for your help.

@8 Pack Where you able to check the removal of the heat spreader?

Sorry to ask again but i'm just waiting on this before ordering parts

On a slightly different note if i where to buy 2 dual channel kits would they work in quad channel on x299?

8 Pack · 8 Aug 2017 at 20:29

Yeah I tried that working fine X99, X299 and X399 in quad no issues.

To be honest I forgot about the heat spreader check. Will do it tomorrow.

My set doesn't do 3333mhz 14-14-14-31 I get 1 error in mem test 86.

What timing s do I slack off?

Ste · 9 Aug 2017 at 18:17

Try 31 to 34

DarkHorizon472 · 9 Aug 2017 at 18:21

Not tried that test but mine is running at 1.41v and 3333 c14.

In the end I just went for the xmp / docp profile at 3200 c14 , changed memory divider to 3333 and upped dram voltage to 1.41v. For my needs it is fine and did the realbench stress test fine for an hour as well as three hours of BF1. No issues so far but I am not an extreme overclocker.

craptakular · 9 Aug 2017 at 18:21

What about that TRC figure? I think mine is at 97

Ste · 9 Aug 2017 at 18:32

That's really high. Mine is 54 at 2T and 60 at 1T

craptakular · 9 Aug 2017 at 18:34

I can't find out what settings are supposed to be, there are loads of them. Is that's a list beyond 14-14-14-31?

8 Pack · 9 Aug 2017 at 20:50

^depends on your board and cpu. Secondary and tertiary timings trained differently according to these factors.

Is it best to leave them auto or google them or something?

Ste · 9 Aug 2017 at 21:10

Tertiary are trained by the board, I think secondary are in the XMP profile. If you've got TRC at 90+ in the custom SPD profile of those 8 pack branded memory's people should be able to squeeze a bit more out of it

craptakular · 9 Aug 2017 at 21:18

I've currently set it to 14-14-14-33-58-T1

It got over an hour without error on memtest86. I stopped it as i wanted to Battlegrounds. Will run it overnight.

Would you suggest changing any secondary or tertiary settings?

8 Pack · 9 Aug 2017 at 21:55

Secondary depends on board bios too. This is where vendors get the balance between performance and compatability.

If it's stable gaming and mem test for a while it's probably going to be stable but yeah you can run more tests ofcourse.
