Unusual ram/bios issue

[Digideath]

This is the weirdest thing I've ever seen. I've never seen this before and I dont think I can do anything about it.

 

I have 32gb (2×16gb) kingston hyperx fury rgb. It has 2 xmp profiles

 

Xmp profile 1: 3200mhz 16-18-18 1t timings

 

Xmp profile 2: 3000mhz 15-17-17 1t

 

I originally had this ram running on an intel system. I tested both profiles and found the 3000mhz profile to be marginally faster in cinebench and certain games.

 

Fast forward to now. I'm now running the ram on an amd system. I tried to set xmp to the second profile in my bios. The bios shows 2 profiles in easy mode. There are 2 separate xmp buttons. However, no matter what one I select, I end up with the 3200mhz profile. I even tried in advanced mode and it shows 2 3200mhz profiles. 

 

So basically I cant select the 3000mhz profile. My bios wont let me. I checked with CPU-z and it correctly detected both profiles.

 

Do you think the bios is bugged and not detecting it properly or is it the case that the 3000mhz profile is an intel only profile?

What motherboard do you have and what BIOS version?

 

You can always enter the RAM frequency/timing/voltage values manually.

Motherboard: msi mpg b550 gaming edge wifi 

It's on the latest bios. I updated it a week ago to add zen 3 compatibility.

 

And I am thinking about dialing in the settings myself. My concern is that it might not be compatible with my amd cpu. That the profile is for intel only.

The Ryzen 7 3770X supports 3200MHz memory out of the box. You can set it to 3000MHz manually then tinker with the voltage/timing until it's stable if it isn't by default.

 

Realistically speaking though X.M.P. should already be pretty close to stable if not stable. A little fine tuning will get you where you need to be if tinkering is necessary.

Well what happened was, i dialed in the memory settings for 3000mhz manually, as per shown in cpu-z here

It worked, however when i was on the desktop it was a bit unstable. I was getting long delays when double clicking on apps. If i tried to load a youtube vid it would hang for about 10s then load. Loads of little problems like that. So no the second profile as it is isn't stable on an amd cpu. Intel yes but amd no. I did try and mess around with the timing but tbh where i got it stable, im as well just using the 3200mhz profile.

And btw sorry for not embeding the pic. Im having trouble trying to load pics on this site. Its probably just me not using the site properly.

A little bump in voltage could have helped.

 

What happens when you try? The site went through a big update only 2 weeks ago or so. We're still trying to work out all the bugs in the new update.

I was worried about bumping the voltage above what cpu-z said so i didn't do that. I'll give it a little tweek and ill try again.

What happens is, at the bottom right, i select "upload image from url". Now i've uploaded a pic to a site and try to use the url given to embed it. "upload image from url". Except when i push the "insert in to post" button, it just goes red and doesn't do anything.

It's probably me not doing it right. Im not sure about the correct image host to use. I've been out the game for a while and its all new to me.

+0.05V aught to be enough. If the behavior doesn't improve your only option is to loosen the timing or just use the 3200MHz profile.

 

Hmn. I've not personally used a photo from URL. I always just upload pictures strait to the LTT site.

I think i've got it. I had to set the dram votlage to 1.375v. And it's up and running. No lag. Not delays. I'm currently running prime95 blend because that is good for flagging up ram issues. It's been going for 20mns. All looks good. I'm going to run memtest86 on it overnight. That will tell me for sure.

I know it's an overclock but this is for every day usage. Because of the timings, its about 8-10fps faster in some games. Especially single threaded games like x3 terran conflict, stalker clear sky and even though it is multi threaded, destiny 2 as well.

The performance of AMD Ryzen has proven to be more more dependant on RAM frequency/timing than in prior AMD CPUs. (With the exception of APUs). You're probably getting tighter timing at 3000MHz than the equivalent 3200MHz which is reflected as higher performance.
