Ryzen 1800x and Corsair Vengeance 3000MHz

[Jito463]

Okay, I could use some assistance here if anyone would be so kind.

 

I bought a Ryzen 1800x and a Gigabyte GA-AX370-Gaming K7 and a kit of 2 x 8GB Corsair Vengeance LPX 3000MHz RAM.

 

I happen to work at a computer store, and I've also had the opportunity to test the exact same RAM on a customer's Asus Crosshair VI Hero, also with an 1800x (we're building it for him).

 

Now, neither system will POST when the RAM is pushed to 2933, but I was about to get the Asus system to POST at 2666.  My Gigabyte system, however, will not POST above 2133.  It tries, then it just resets the timings and reboots at 2133 again.  I even tried flashing with the latest beta BIOS (F3b), but no change.  I do realize this is all new technology, and it may well be sorted in future BIOS updates, but I thought I'd take a crack at manually adjusting the settings.  I've messed with overclocking before, but it's probably been at least 12 years, probably more.  I typically just let the MoBo set the timings and leave it alone.  That said, I'd appreciate some assistance in determining the correct settings I should shoot for to get this running at least 2400, preferably 2666.

the best you can do really is try using really loose timings to get it to boot and then tight them step by step until it stops working,

Any recommendations in that area?  Like I said, it's been a long time since I've fiddled with memory timings and such.  I could probably work it out eventually, I was just hoping to take a shortcut.

Thanks, that does give me some areas to start investigating.  I appreciate it.

Just wanted to add that I've got my RAM running consistently at 2666, 15-15-15-15-36.  I tried using the XMP profile for 2933, and initially it seemed to work.  Unfortunately, after reboot it gave me an error beep and reset the timings again.  In any case, I'm happy enough with 2666.

 

My problem was that I set the clock speed, but was trying to get the BIOS to automatically set the timings.  I hadn't considered manually setting the timings, as well (much less setting the voltage manually).  Thanks again for your help.

Really now? XMP profile worked for me, mine runs on 2933mhz just fine, but it's an Asus motherboard.

I'm assuming at this point that a future BIOS update will likely fix it.  In any case, it'll be at least another week before I swap it out as my primary system, as I'm still waiting for my bracket from Corsair for the H115i (last time I checked they were saying the 31st was the new ship date).  Such is life on the bleeding edge.

True enough, my brother and I bought my 1800x on pre-sales which had a discount that made it 1700x price, the motherboard on the other hand took a bit more than a week to arrive after the CPU was already here, by the time Asus already had a newer bios available on their website and we did it, no issues and very stable so far.

 

But I still rather use my i7 for personal use.
