[Request] Unlock memory multiplier and voltage

Hello, first time posting a thread personally in this forum :smiley:

I am currently curious wether this motherboard could be unlocked for Memory overclocking? My motherboard is a Gigabyte B75M HD3, and from what i saw in the past that the Gigabyte B75M D3H rev 1.0 could overclock the ram (i cant post the link to the blog here somehow?). Current ram that i have is a pair of Team Vulcan Red 16GB Kit 2133, and i really wanted to run it at XMP speed of 2133. will this be possible to be modded? Thank you.

*my bios dump file (cant post the direct .bin file so i compress it :"D)

Well since ur posting every where and different subjects and new to this forum, i suggest u start taking advantage of all guides, user experiences, similar post etc… on this forum.
Without reading, searching u wont learn.
The forum is for reading and help users on issues they encounter… and themselves can share also their experience, not for doing their work.
So like this… ull find a lot of data already shared and very helpful on ur endeavors.
Lets see… u have a Sabertooth P76, ECS H61H2 MV, GA-B75M-HD3 and a Strix Z270F… u’ve got a lot to read.

PS: There’s a search box on the forum.

Aren’t memory multiplier and voltage settings not available under M.I.T -> Advanced Frequency Settings?


They are locked, cant go past beyond 1600mhz, also the xmp will only maxxed out at 1600mhz cl 8-9-9-9-24 (not any better from my personal timings)


i think so, i started to look back at my old motherboards (except my z270f, which i sold to my friend just yesterday), and thingking of the capability it does have, but im still curious that if my b75 (or even my h61h2 mv) memory multiplier could be changed above the limit. Also thanks for the advice :smiley:

need only OC skill ?
all MOBO is unlocked .,.no need any MOD :confused:

full RAM - VCCSA / VCCIO /RAM voltage + SA DOMAIN setup ?

and CPU limit and DDR3 voltage is problem ? .,.,.if you have normal cpu and normal mobo - here is all limited :confused:
,…,only kill your mobo

// send full spec "cpu name"
and screen from bios "where trying OC" // voltages

///
OC for this old system is bad idea "all is before dead"

or old way FSB /RATIO / LOCKED RAM :smiley:


It’s on my signature, im currently using E3 1240 V2 and B75M HD3, just wondering if the multiplier could be unlocked OR the mobo could run the XMP at 2133, not wishing for oc ing the cpu itself. also the bclk, vccsa,io, and ram voltage is locked.

Gigabyte B75M HD3 .,.,is old non-OC mobo
and cpu official support : Memory Types DDR3 1333/1600

memory type ,.,.dual rank or single or banks type – all this changes limits

send how to look bios ? :smiley: ,.,try find ADMIN key for advanced access “GOOGLE” .p
,.,.but non-OC mobo and old parts + new OC – sometimes full brick !!!

this not have UEFI ? ,.,.old legacy bios only


i have this motherboard full uefi mode, and windows installed with that settings (logo till boot to windows instead of windows logo on boot).

0x40CB8 M.I.T. (0x6 from string package 0x0)
0x43895 System (0x8 from string package 0x0)
0x4EA8F BIOS Features (0x2F from string package 0x0)
0x4FE88 Peripherals (0x29 from string package 0x0)
0x520FB Power Management (0x2B from string package 0x0)
0x5290F Chipset (0x2D from string package 0x0)
0x52BBF Security (0x4D from string package 0x0)
0x52D97 Save & Exit (0x60 from string package 0x0)

all this DOMAINS you see in your bios access ?

CTRL+F1 key to enable advanced BIOS setup features ?? "boot key for ADMIN"
and don’t brake mobo

edit
// but still depends on MOBO capability vs ram type / cpu

Only two are missing: Chipset and Security. Do you know how to deal with 1600mhz limit?


Yes, all of those are the domains that i saw in the bios. i saw the options, and everything related to ram speed and voltage is locked. xmp only maxxed out at 1600, i tried to edit it to give USER on memory frequency so that i could choose that option, but still it wont work, it’ll just wont type the ram speed, or the multiplier will just still be in 16 at max. im wondering how could i unlock the multiplier for ram and xmp so i could run at 2133mhz, and unlock the voltage options on the ram only.


ok i will try this later :smiley:

I think his limit is a normal board ,…,not BIOS :smiley:

basically less capacity 1R memory is here better
,.,.,nowhere do they write that the board supports 1600mhz+ for all memory types !!


if you want to tuneup – SA DOMAIN + SA voltage / IO / VDD
or is this a condition only FSB - this raise FCLK "SA AGENT"

FSB - working/compatible ME FW for some mobo .,.and for this old IVY ?? I don’t remember anything anymore

try admin mode "for unlock all access"
,…,search all options for any OC LOCK / CFG lock .,…,etc

find more info for your RAM - HWINFO / CPU-Z "chip name and RANK"
monitoring - hwinfo

and in HWINFO/CPU - function "overclocking status"
,.HWINFO/ME/ICC - BCLK


///
but consider the potential risk ! OC for old HW is extreme risk …,.,not all works like from factory :smiley:
good luck

,., … for mod you need another help "i not modding bios" ,if at all possible.

edit ,…,translation fix

Okay i just tested CTRL+F1 does not working, also here the regions on my bios:

and here is XMP options on bios, note that on boot it does not turn 1.65v, it stays at 1.5v as what i saw on monitoring:

xmp off.jpg

xmp on.jpg


How do i search this? AMIBCP?


it is already told that on my signature you could see the specs, its Team Vulcan 2133.
Anyways here the cpuz and the timings of my ram running on 1600mhz:

unknown2.png

XMP enabled for stability - VDD 1.65V
+ memory multiplier ?

but your memory is 2R - faster targets your mobo or cpu limits

//performance enhanced - custom ,…exist ??

The VDD Will remain unchanged even if i use XMP. memory multiplier cant be more than 16, it always revert backs when i try to type above than 16.

custom does not exist, but i could manually do my ram timings as what i gave you earlier.

unfortunately I think the official spec does not take into account 2R memory
or only “installed” one memory stick.

CPU - official max 1600mhz "and Xeon cpu"
mobo + OC 2200mhz - but what type of memory and capacity / and ideal cpu ?

,…try wait for another users
unfortunately I don’t know more :confused:
