Corsair Vengeance 4133MHz RAM freezes after boot.

[Vinja]

Hello. I am new to this forum, and overclocking. My name is Delta. This is my rig: http://www.overclockers.com/forums/...t-edition-to-our-family?p=8025239#post8025239

I bought 4x8GB Corsair Vengeance LPX. They are installed, and watercooled. My motherboard is only running them at 2133MHz even though they are rated for 4133MHz. I have tried to load the XMP on the BIOS, but when XMP is enabled, 4133MHz is enabled, 20 seconds after startup the computer freezes, then restarts. As of today's date (8/7/17), my BIOS and drivers are fully updated.

Corsair told me over the phone "You shouldn't expect your memory to run at 4133MHz even though it says it on the box"
Gigabyte is impossible to get ahold of. I spent an hour on the phone before surrendering to use their callback service. Gigabyte never called back. I left them a ticket. It remains unanswered, but says I should wait 3-7 days for an answer.

The manufacturers are not helping. Can you guys help me get my RAM to work better (even if not at a full 4133, atleast higher than 2133)?

My specs are on the link I put in the beginning, but for simplicity's sake, I will put my motherboard, CPU, and RAM specs here.

Thank you very much for your time, and I hope that there will be more I can learn from this community so that I may compete on 3D Mark.

I would start from something like 3200 14-14-14/15-15-15 1.35V manually, then 3600 15-15-15/16-16-16 1.35V, then 3733 16-16-16/17-17-17, then 4000 18-18-18/19-19-19 1.35V and 4133 at higher VCCIO/VCCSA or whatever you have in your BIOS what affect memory overclocking and 18-19-19 or 19-19-19 main timings / 1.35-1.45V memory voltage.
Check if memory is in 2 and 4 slot counting from CPU side or the one marked as 1 and 2 ( a/c, a1, b1 or something like that ). Usually 2 slots are overclocking better and 2 a bit worse.

There are many variables that may affect maximum memory frequency so sometimes it takes time till you figure out what is causing issues.

Thank you for your quick response! First, there are 4 sticks of memory, so all 4 slots are in use. I'm going to try to load up the BIOS again and see if I can get into some manual configurations. I couldn't quite figure it out the other day, but I have a little extra time today, so I'm going to try to get into manual configurations and try your exact suggestions. I really appreciate your help.

When you say 14-14-14, what exactly do you mean? My memory says it is rated 19-25-25-45. You gave me 3 numbers rather than 4?

Somehow I missed the fact you said about 4 memory modules and I'm not sure how So all 4 probably won't run above 4000. You can try other settings and when you won't be able to boot then check higher VCCSA voltage. +0.1V should be enough. Up to 10% voltage is generally considered as safe.

Main timings 14-14-14 ... 4th is less important you can try 14-14-14-32, 15-15-15-35, 16-16-16-36, 17-17-17-38, 19-19-19-38. Also check command rate 1 and 2. I guess you will need 2 for higher clocks.

I am sitting in the BIOS, I am in the following menu: Advanced Memory Settings->Channel A Memory Sub Timings. I have set Memory Timing Mode to Auto, Manual, and Advanced Manual. I am unable to modify the values in CAS Latency, tRCD, tRP, and tRAS, no matter which setting I set the Memory Timing Mode to. I'm completely locked out of manually changing the timing for some reason.

Ok, so here is what the Gigabyte rep from tech support said.
Go to BIOS, and step up the memory multiplier 1 by 1 until you reach instability, then step down 1.
Is there more to this? So far I have stepped up to 27 successfully.
