CPU Compatibilty List

Yes eccential, it boots fine but crashes while gaming at 1.35v.

Best I can get so far to run stable is 2800 at 1.28V while using the XMP Profile timings of 16-18-18-36-54. Anybody have any suggestions?

Thanks for the update DTingman.

The inexpensive and locally available Corsair 2x16's are already loosely timed but I'd love them to get up to their XMP rated speed of 3200. Any suggestions on how to get more out of these?

OK, this is a good start, next please show us the zentiming when you manage to boot into windows running 2933. We need to check many other things when it is in 2933 to find out what crash.

OK your problem is ASRock's bios didn't setup the many correct voltageseses for you....

Hence now you will need to set them manually.

I already given LINKS and replies to you regarding the voltages that you need, did you not read them?

Or you didn't understand them?

You were correct that the Secondary timings didn't seem to change when I set the XMP profile so I plugged those in manually, but it still doesn't run stable anywhere near 3200. The only thing I've done so far that helped was without the XMP profile, upping the voltage to 1.25 and that seems to allow me to run stable at 2667. good luck.

giving the impression you understand secondaries timing - means should have enough skill to understand the other parameters too (including voltageseseseses), but I'm surprised you didn't see all the voltageses required???

cx5 wrote: Hi @DTingman, getting the secondaries is only part of it, if you read all the posts replies & history in the links and the link's links I've given then you would have seen CLDO_VDDP, which is not the regular simple VDDP alone, they are two completely different thing, you will have to dig into the bios everywhere to find it. Back in 2017 /2018 the CLDO_VDDP was put very deep and default 0.7v hence most XMP failed. Nowadays it's right_UNDER_inside of the SOC voltages area on the tweaker page, you'll have to dig in deep. You need 1 volt for CVLDO_VDDP, recent ASRock bios some versions default to 0.95v which partly works and don't. This CLDO_VDDP has something to do with infinity fabric, the faster it runs the more voltages it requires, my 3600 needs 1 volt, when 0.95v will sometimes crash game. btw, what is your full spec? also please provide a zentiming screen capture, it is extremely important to see VSOC and CLDO_VDDP, etc etc etc... keep the bios agesa 1.2.0.7 try 1.4v dram more voltages here https://forum.asrock.com/forum_posts.asp?TID=24829&PID=100979&title=xml-profile-2-0-not-working-with-ram#100979

everything is written to you in above, did you not read it? or which/what part you don't understand?

>>>>>>> try 1.4v dram <<<<<<<< why didn't you do this ????

even @eccential told you to run 1.35v but why don't you run it????

I don't know exactly which Vengeance model you have, since there are so many, and it probably isn't even that important because Corsair would just use whatever brand it can buy for cheap (Samsung/Micron/SKHynix/...). But one of the specs for a 8GB Vengeance model I found on Corsair's own page says 2133 15-15-15-36 1.2V (base) and 3200 16-20-20-38 1.35V.

because you didn't set ALL the OTHER voltagesESESEES hence crash.

which I've repeatedly given you in above links and written text.

Hope you realized and manages to catch them this time.
