Hey everyone. I'm just wondering what everyone's experience is with getting DDR4 clock speeds up to 2933/3200. Has it worked for you? Did you use sticks on your motherboard's QVL? Did the XMP profile work? If you had to manually set or loosen timings, what did you settle on? Are there any RAM overclocking guides that apply well to AM4 boards? Most of them seem to assume you'll be changing the BCLK and/or that you have a working XMP profile to start off of.
I'm running an R7 1800x at stock clock on a Gigabyte AB350-Gaming 3. I got 2 sticks of G.Skill Ripjaws V 8GB 3200MHz DDR4 memory to go with it (F4-3200C16D-16GVKB with rated timings at CL16-18-18-38 at 1.35V). This isn't on the motherboard's QVL, and I suspect it doesn't use the Samsung B-dies people are recommending, so I wasn't really expecting the 3200 XMP profile to work. Unsurprisingly, it doesn't. I was however hoping to get speeds up to 2933 or even just 2666. Unfortunately, I've only been able to bump it up to 2400 which I've kept at 16-18-18-38. After reading up on timings, I decided to try something very loose like 20-24-24-46 and 1.35V at 2666 to see if it'd POST, but no luck. This is my first time messing with RAM clocks (or DDR4 at all), so I hope I'm overlooking something or that this is something that will be corrected with further BIOS updates. I'd like to avoid buying different RAM (maybe the G.Skill Flare X that's on the CVL when it's back in stock), but I guess that may not be possible. I'm running the last F6d beta BIOS version released a day or 2 ago that supposedly increased memory compatibility.
Du bist wohl nicht der Einzige....Wenn die Kiste mit den Standardeinstellungen stbail läuft, würde ich erst einmal abwarten. Ende Mai soll ein AGESA-Update von AMD kommen, das Verbesserungen bei der RAM-Kompatibilität bringen soll. Evtl. hast Du dann mehr Glück. Wenn's gar nicht läuft, tja...
Grad Deinen Post gelesen. Ja wenn Du 7 mal booten musst, dann misslingt das RAM-Training. Da kannst Du nur versuchen, die SOC-Voltage anzuheben, die Speicherspannung anzuheben und evtl. hast Du bei Deinem Board auch die Möglichkeit, eine DDR Boot Voltage einzustellen. Zumindest gibt es das beim Crosshair.
