Question MOBO does not support xmp help

[Disheveled_Human]

I just got a new rig, installed is 3600MT/s CL18 T-Force Vulcan Z 2x8gb Ram. The motherboard is a ASRock H610M-HVS the Bios is updated. I cannot figure out how to set ram speeds from default 2400mhz. Note the board is rated at a max of 3200mhz and does not support XMP since its a budget board. Can someone help me out? My issues are basically I need help manually setting the timings for 3600 CL18 rated ram to 3200mhz on this MOBO.

Great!... after all XMP is just a programmed overclock. And I'm not 100% convinced the motherboard is incapable of using the XMP, I checked the BIOS manual, and it says there's an Advanced Mode for the BIOS, pressing F6 which contains additional hardware configurations... have you found that hidden window?

Something else, older motherboards had a 3 pin setting for the BIOS jumper, and one was considered a Configuration Mode, and it showed an additional BIOS window with advanced setting. See if your motherboard has that capability... it may have been replaced with the Advanced Mode, but who knows(?).

1 question what is the deal with FSB : RAM the ratio is 1:24 is that normal or do I need to tweak something? It was at 1:18 prior.

The only way to change any settings on this crusty MOBO is to go into F6 advanced options. The annoying part was there was no drop down xmp menu with proper tunings, only a read only one in info which was set at 2400,2500,2533 and 3600. Because my ram is CL18 and 3600 to get 3200 was a bit annoying because the max my mobo and processor could support was 3200. In any case im glad it worked out.

Hopefully 18-20-20-40 @3200 is faster and overall better than 16-16-16-39 @2400 .

FSB in RAM
Short for Front-Side Bus, FSB is also known as the processor bus, memory bus, or system bus and connects the chipset. The FSB is what we have seen change from 66 MHz, 100 MHz, 133 MHz, 266 MHz, 400 MHz, 800 MHz, 1066, 1333 Mhz, 1600, 1800, 2000, 3000, and up to the 5000 Mhz range and intermediate speeds through the years.

By default, FSB speed and memory are usually set to a 1:1 ratio, meaning that increasing FSB speed by overclocking the CPU also increases memory speed by the same amount.

Your motherboard is rated at a max of 3200 MHz
Your CPU is rated at a max of 3200 MHx
Your RAM is rated at a max of 3600 MHz, but can only work at 3200 MHz because the motherboard sets the limit.

A 1:2 ratio is the equivalent of 20% increase in RAM FSB from 2400mhz to 2880 Mhz

I read you're trying to increase your 2400 MHz RAM speed to 3200 Mhz, so the ratio should be 1.33

The timing: Higher timing is supposed to transfer more data at a slower speed, while a lower timing transfers less data at a higher speed, so the ideal timing would depend on what you'll be using it for.

Im guessing gear 1 made 1:33 into 1:24 then. I also switched a setting from auto to 133mhz other option was 100mhz, I forget what it was for, but because my processor is beefy and my ram is capable I just turnt everything up and it is stable, not only that but I am getting better fps in games anywhere from 3-10 depending of the title. Also it seems like less ram is being used when doing office stuff.

Sounds good!... just wonder what those 133mhz from 100mhz was about.. such low numbers pertain to the start of the century.
