Overclocking is at your own risk, YMMV. What you are seeking is so small of a difference that it will be un-noticable.]]> Thu, 31 Mar 2022 23:44:37 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97684&title=z690-pg-velocia-not-booting-with-xmp-enabled#97684 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97662&title=z690-pg-velocia-not-booting-with-xmp-enabled#97662 Author: veggiss

Updated BIOS, no luck. I have now tested both stick separately, I the pc works like a charm @6200Mhz. With both inside it crashes, or refuse to boot at all.

Time for a new mb.]]> Wed, 30 Mar 2022 22:59:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97662&title=z690-pg-velocia-not-booting-with-xmp-enabled#97662 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97660&title=z690-pg-velocia-not-booting-with-xmp-enabled#97660 Author: veggiss

Missed the one yesterday and today, I'll try those!]]> Wed, 30 Mar 2022 21:50:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97660&title=z690-pg-velocia-not-booting-with-xmp-enabled#97660 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97656&title=z690-pg-velocia-not-booting-with-xmp-enabled#97656 Author: Gatt59

I forgot ... three bios updates improved the memory compatibility.

Good luck!]]> Wed, 30 Mar 2022 13:09:56 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97656&title=z690-pg-velocia-not-booting-with-xmp-enabled#97656 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97655&title=z690-pg-velocia-not-booting-with-xmp-enabled#97655 Author: Gatt59

Have you updated the bios? ASRock has updated the Velocita bios many times from January. The last one just yesterday.

One of the bios has an improved Intel XMP version (v1.2) and the last one (v8.03) even the possibility to "Load Intel Base Power Limit Settings".]]> Wed, 30 Mar 2022 13:05:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97655&title=z690-pg-velocia-not-booting-with-xmp-enabled#97655 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97653&title=z690-pg-velocia-not-booting-with-xmp-enabled#97653 Author: veggiss

I managed to boot the system with the sticks at 6200MHz, but the system is far from stable. Took out one stick an ran just a single, and that worked out fine.

I'll test the other stick tomorrow.]]> Wed, 30 Mar 2022 07:05:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97653&title=z690-pg-velocia-not-booting-with-xmp-enabled#97653 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97643&title=z690-pg-velocia-not-booting-with-xmp-enabled#97643 Author: Gatt59

I'm using the same motherboard with an Intel Core i9-12900F and 2x16GB Corsair Vengeance DDR5 @5600Ghz (36-36-36-36-76). If I choose the XMP 3 profile I don't have any problem (work, gaming and stress tests).

I guess that the 6200GHz RAM is the problem.]]> Tue, 29 Mar 2022 19:54:58 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97643&title=z690-pg-velocia-not-booting-with-xmp-enabled#97643 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97624&title=z690-pg-velocia-not-booting-with-xmp-enabled#97624 Author: veggiss

Thank you for your reply. Looking around it looks like the cpu should handle the speeds without any issue, but not on my rig. I adjusted the settings back down to auto now, and the system is stable.

Guess I need to try a different mb/cpu/ram combo.]]> Mon, 28 Mar 2022 18:59:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=97624&title=z690-pg-velocia-not-booting-with-xmp-enabled#97624 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=94550&title=z690-pg-velocia-not-booting-with-xmp-enabled#94550 Author: threadzipper1957

Extra note:]
When you OC above 4800MHz, only a synthetic memory benchmark will show better results, but usually it does not have much impact on the overall performance of the system, lower latency timings should give some performance increase
Maybe it is different with DDR5, but with DDR4, it never did much good]]> Wed, 23 Mar 2022 17:46:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=94550&title=z690-pg-velocia-not-booting-with-xmp-enabled#94550 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=94549&title=z690-pg-velocia-not-booting-with-xmp-enabled#94549 Author: threadzipper1957

Dear Vegard,

The memory controller is not on the board, it is integrated in the CPU, and in this CPU runs optimal at 4800MHz with DDR5, 3200MHz with DDR4
https://ark.intel.com/content/www/us/en/ark/products/134599/intel-core-i912900k-processor-30m-cache-up-to-5-20-ghz.html
XMP is basically oveclocking for beginners, it is a profile that is supposed to work on all the thousands of combination of CPU, chipset and mainboard.
It is not guaranteed, and you must always select it manually.
Maybe the memory controller inside the CPU cannot handle 6200.
Using manual settings allows you to lower the latency timing, because XMP is far from optimal.
When using a tool like thaipoon burner, you can see the SPD and XMP profiles stored on the SPD chip, on the memory.
One tip:
USe a FAT formatted USB stick, it is easy to make BIOS screenshots by pressing the f12 key.
Later you can print some of these, and use them to set different timings.]]> Wed, 23 Mar 2022 17:44:09 +0000 https://forum.asrock.com/forum_posts.asp?TID=22362&PID=94549&title=z690-pg-velocia-not-booting-with-xmp-enabled#94549
