I bought a set of Corsair Vengeance LPX (2 x 8gb) sticks and booted the PC. I can see they are running at 2666mhz but the max speed is 3200mhz. Any idea what i can do to change that to 2999mhz as this is the max supported by the R 2600?
The sticks I have are the CMK16GX4M2B3200C16
Tried that. I had blue screen issues so turned that off. I have the Gigabyte B350
how long did you wait at blue screen? sometimes it can take 5-10 min for the bios to update and set itself up. Bluescreen and restarts can be common during this.
Is it running the latest bios? maybe needs to be updated?
Your pc can't run it at those speeds. Your best bet is to incrementally overclock your RAM. Sucks but that's what I had to do. I can only get mine to boot at 3000mhz.
I had similar issues with my R 3700X and 3600mhz ram, and initially my ram also didn't ran at full speed, this is how I fixed it:
you will need to do both, just enabling XMP alone wouldn't do it
hopefully the above will help you out
There's only 1 profile which is 3200 and when I go with that PC goes nuts blue screen errors etc
damn
I had similar blue screen issues as well when I built my system at the beginning of this year, but I can't recall the exact details right now, I will post it if I can remember the fix for it, but it was something along the lines of kept experimenting with different options in BIOS (could be XMP or something else).
otherwise, just in case you haven't done so already, did you upgrade to the latest bios, put the ram in the right slots, checked ram/motherboard compatibility? (sorry for the obvious questions :))
I'm over it man haha
After you have updated BIOS like FW190 mentioned and if it doesn't fix the issue, select the DOCP profile again and manually set DRAM voltage to 1.4 and SOC voltage to 1.1.
No option to change voltage
The specs says that its tested speed latency, voltage and speed is 16-18-18-36, 1.35V and 3200MHz/(1600+1600).
Can you make your mobo manually match that, and try reset settings to default first if you randomly changed anything before? Otherwise, try contacting support from where you purchased that RAM.
You need to set them to 2933mhz or get 1usmus ram overclocking tool and put it in manually. (the timings, etc.)
I give up man
make sure you're on the latest AGESA revision, go to your motherboard BIOS download page and see if there's a new update that improves DRAM compatibility
Otherwise you're going to have to manually dial in DRAM timings. It takes a bit of your time (pun intended) but it's most reliable to get high speed RAM working on a old B350 board.
in my experience old B350 chipset doesn't work that well with RAM faster than 3000mts, I recommend 2933mhz for stability
I'm thinking i should upgrade the motherboard to b450 in the next 12 months maybe
plz udpate the title, I thought u were talking abt RAM 1500 :p
In the computing section?
No one has posted the correct answer so thought I would jump in.
The B350 chipset only natively supports a max of 2666mhz.
You need to overclock if you want higher speeds.
Thanks. That's what it is running at the moment at 2666mhz but I can only OC to 3200 via BIOS by enabling XMP Profile 1 (only one available) and when i do that the PC shits itself. I can't work out how to OC to 2933mhz to see if this works.
What's the full model number of the board?
You load XMP profile 1 at 3200 then turn the speed down manually.
The setting will be there you just have to find it, same with voltage tweaks. Check the over-clocking menus - manual RAM speeds/voltages and SOC voltage are probably in there
Edit: pages 21 and 22 of your manual show you where everything is. RTFM
Pretty sure the Zen+ memory controller does not like higher memory speeds like the Zen 2 does. I remember reading that faster memory support is temperamental on the Ryzen 2000 series that you have. 2933Mhz is the maximum official supported speed.
You might have to increase RAM speed incrementally and test until your computer stops being stable and you find your fastest max memory speed.
My Zen+ CPU (also a 2600 incidentally) on B450 is running at 3600c16 right now rock stable overnight in Memtest Pro - the board/bios for the board is the limitation here, or their RAM is faulty.
Edit: I could get 3733 to post BTW but even loose as it was unstable due to IMC I assume, Micro Rev E. Pretty much every 2000 series chip should be able to do 3200 in its sleep, most can do 3400 with just XMP
Yeah from what I read it was a bit of a silicon lottery, that's why some chips were better than others with memory speeds. The motherboard design had a bit to do with it as well with the amount of signal layers and layout, Zen+ chips were sensitive to that.
Go into your bios and activate XMP/DOCP/EOCP (the exact depends on what motherboard you have).
