I see now, thanks! Maybe BuP4uk can figure it out on his eventually! For the Maximum Memory Frequency, see the setting right above that, I think maybe this is some fail safe or "Safe" memory speed thing, due to the one right above that. "MRC ULT Safe Config" but it's disabled by default so maybe changing the one you mentioned wouldn't apply at all, only a test would let you know. If it does nothing, enable that MRC ULT Safe Config and test again, then if nothing you know it's not what you want to downclock memory.
I think this is how you do what you want, you need to set several items to change the ram speed (Now, this may get limited by what you mentioned above, if enabled and set to some value = leave disabled, don't change and use this instead)
Memory profile >> Change to custom
Memory Reference Clock >> Choose 100 or 133, based on your desired outcome speed
QCLK Odd Ratio >> Enabled, so all multipliers can be used at either 100 or 133 above
Memory Ratio >> Set whatever your want (memory Reference Clock 100 or 133 x value set here >> 3-15 available)
Memory Voltage is also available to change, as well as many individual timings and command rate (NMode 0=Auto, 1=1T, 2=2T)
Hey, sorry to hijack the thead, but it's kinda related.
I have a GL502VSK and I want to flash a modded bios in it, but before I start playing around with it, I want to make a backup of the stock bios. I have an SPI USB programmer (CH341A with a SOIC8 clip) and a few spare blank chips, in case I need it.
So, is it simple as saving a backup of the bios chip or there's something more to it? If something goes wrong, can I just reflash that backup back into the bios and it will work?
Would it work if I flash the bios file available for download on the ASUS support page?
Sorry about all the questions, I just want to play on the safe side heh
Thanks!
You need to verify that your backup is valid before you write anything, first open in hex and make sure it's not all FF or 00, then open in as many other BIOS tools as you know and see if it looks OK, acts like stock BIOS etc.
Many BIOS downloads from Asus are only partial updates (BIOS region only, missing FD, ME, GbE often). So check the BIOS you download in UEFITool first before you program, if it's not complete you need to use it to make a complete image or ask someone to do for you using your backup file. This is needed since LAN MAC ID is often in GbE region, and your board details are in BIOS region in SMBBIOS module and or padding etc, so will also need extracted and put into stock first

Thanks for the info! I'll start playing around with it.
Is there any risk of corrupting/damaging the BIOS trying to dump it?
If you have the programmer attached backwards it can heat up the chip super hot in a very short time (Seconds), it will burn your finger almost, so feel for that or make sure it's all correct. Here is an image guide on how to hook it all up

Other than that, as long as you do not write to the chip, it should be fine. You may not get verified or valid dump until you find the right software version or chip ID. If W25Q64FV choose BV instead and use software 1.30
Great! I'm good to go then.
Thanks!
Please dump your BIOS region with FPT >> FPTw.exe -bios -d biosreg.bin
