Ram issues

[BartJY]

Hi Folks,

 

I'm trying to upgrade my amount of Ram, 16 to 32. Currently the Corsair Vengeance LPX 2 x 8 overclocks at 3200, no problem. I try switching the ram to 4 x 8 sticks of Corsair Vengeance RGB Pro and it won't overclock. It sits at 2133. I've spent 2 days working on the problem, tried every combination of advanced BIOS settings, but it still only comes up to 2133. Why will it not OC to 3200? Does the MoBo or CPU not like more than two sticks of Ram? Does it not like Corsair Vengeance? Any suggestions or incantations that you know of that will make it work? If not, what amount of memory and make do you know for sure will work. Will a different 7 3700X Ryzen CPU let it work correctly? Is it a problem with earlier generations of CPUs?

 

Asus ROG Strix B450-F Gaming

Ryzen 5 2600

Corsair Vengeance LPX 2 x 8 3200 DDR4

Wanting to replace with Corsair Vengeance RGB Pro 4 x 8 3200 DDR4

Latest Bios.

 

Thanks

IIRC some boards won't/can't run the RAM at rated speed if all the RAM slots are full.

Again, IIRC there isn't a solution to this other than hardware replacement, but I am not an AMD expert.

So populating all the slots might me an issue. I hold out hope that there might be a work-around for that. Do you know if two slots will work with 2 x 16 gb sticks?

 

Thanks

I'm at work right now, so I can't look, but if you check the website for the mobo you have, it'll tell you what RAM configs work (4x4, 4x8 2x16, etc)

Also, always make sure your RAM is on the QVL...it can make a difference at the edge cases

[Radium_Angel]

The other option is manually setting the timings and voltages on the RAM stick, but I"m *really* not an expert on that, but there are plenty of folk in the RAM section of this forum that could help out on that.

The motherboard I have is the Asus ROG Strix B450-F Gaming. ( Not the B450-F II )

I've tried manually setting the timings and voltages. Nothing seems to kick it up to 3200, it's still at 2133.

I'm at work so I can't check this stuff, but see if this YT video helps

I appreciate the attempt at help with this YT link. But, I tried that video two days ago with no success. Now you can start to understand what I've been through. I've pretty much tried all the YT videos the subject. And I've tried many timing changes in the BIOS, yet nothing seems to get it to 3200.

What des the mobo manual have to say?

Is your RAM on the QVL?

[BartJY]

I was told that it was, but I haven't looked so I can't swear on it. I'll have a look. The manual doesn't say which make, only to look at the QVL.

After 4 days of banging my head against a wall in a futile attempt to get the four sticks of memory to overclock to 3200 speed, I think I've found the reality of the situation. Seems that 2ed generation Ryzen CPUs can only overclock two sticks of Ram. Put in four and it will always defaults to 2133. On the other hand, 3rd generation CPUs can overclock 4 sticks of ram to 3200. I've been wanting to upgrade to a 7 3700x for some time now, perhaps this will push me to spend my hard earned cash on a new CPU.

 

Thanks for sharing in my frustration.

 

Cheers
