issue with ram

[Kumoko]

well when i try to OC using profile one 3600 which is the ram is rated at it gets unstable :/ is it becuase i only plugged in 1x8 of the cable for the cpu? 4 ram with 3600 it works with only 2 though

xmp sets the dram speed, voltage, timings etc.. not the cpus imc voltage

xmp does not do anything to the cpu, just the ram multi, which is multiplied by the fsb/bclk
cpus imc should be <1v, dram voltage is 1.2v for ddr4

you have to set an xmp profile on the cpu in the bios menu, which in turn overclocks the cpu, which allows the ram to be overclocked.

XMP doesn't overclock the CPU, it just doesn't. If anything, with Intel, higher RAM XMP profiles will just use more CPU IA and SA voltage, but it doesn't overclock the CPU.

yet, my xmp wont work unless the xmp profile is set on the cpu, which overclocks my cpu, thus sets the ram to the specified speed.

if my cpu didnt get that setting, i get a bios notification saying overclock failed.

^ this

if 2 dimms work, and swapping to the other 2 dimms work
then the imc needs a small voltage bump (cpu v something not the dram voltage), or speeds need to be lowered
post a a ♥♥♥ of the bios cpu voltages

if i remember correctly if i set the XMP it will auto b put on 1.35 not sure if that includes the cpu but CPU Z is showing 1.3-1.4 V but the XMP will only work if i have only 2 ram inside anything more then that just gets unstable

Because you need to either increase voltage or lower DRAM frequency/adjust timings. Most kits above 3200 MHz are 2 DIMMs because it's harder on the IMC to run faster settings, you have to use more DRAM voltage and voltages for the IMC to sustain those settings, or drop the frequency.

My RAM has an XMP profile of 4400 CL19, but since it's too harsh on the IMC to run that on 4 DIMMs, so it only runs stable on 4 DIMMs with 4000 MHz.

That's still not a CPU overclock just because it's in CPU settings

All XMP actually does to the CPU is adjust voltages related to the IMC, which Intel claims could void the warranty, but it's just to cover their own behinds, because they're not going to deny people their warranty for using XMP.

The fact that it doesn't work properly is an issue with your motherboard BIOS specifically, because the board manufacturer messed up.

my cpu goes from 3.6ghz to 4ghz with said setting, which allows the ram to clock to 3000mhz

and to be exact, it changes the Blck, multiplier and a few other things, but most everything shows as set to auto.

tell me again how my cpu isnt being overclocked...

not changing the cpu setting to the specified xmp profile, but setting the ram to the xmp profile, would in fact cause a "failed to overclock" notification, so... there is no issue with the board, nor did the manufacturer mess anything up, sorry.. not sorry.

is there a guide to that i dont really wanna play with voltages so i set it on auto

just set the xmp profile in the cpu settings bios menu, then make sure your ram got set to the specified xmp profile settings/speed, save and exit, then everything should be working fine, if you want, you can jump back into the bios menu and see if your ram is running at the intended speed.

hopefully you plugged that second cpu power cable in tho.

Literally doesn't change anything with my 10850K and Z490 Tomahawk at stock with XMP, so it's still related to your specific circumstance.

I've had many systems using both Intel and AMD hardware and have NEVER seen XMP overclock the CPU. It's your motherboard, or it's simply user error.

its just how my cpu and mobo work, not a user error or a motherboard error....

If XMP always overclocked the CPU, it wouldn't even work with locked CPUs or on locked chipsets because the CPU multiplier is locked in those instances, they'd have to make exceptions in firmware specifically for XMP, but that doesn't happen. Something else with your configuration specifically is changing the CPU multiplier with XMP enabled, most likely something that the BIOS maker had to or chose to do. Point is, don't confuse what's specific to your BIOS with the actual standard. This isn't the way it normally works, bottom line, so don't go around telling people that it does.

Intel XMP stands for Extreme Memory Profile, which is just an alternative to JEDEC specification in that it allows memory manufacturers to create customised profiles for their high performance memory, it is not typically related to the CPU to that degree, it's usually only related to the CPU's integrated memory controller (IMC) and the motherboard's power management integrated circuit (PMIC), the latter of which has been moved to the RAM modules themselves with the release of DDR5.

im not confusing anything, tho you seem to have been confused on whether or not xmp was in fact overclocking my cpu, which it is.

the fact you jumped into the thread to tell me something wasnt happening with my own computer, but it was actually happening, is where the issue was.

You can set the XMP profile up and then just increase DRAM voltage. If need be, adjust SOC voltage. For Ryzen, you don't want to exceed 1.2V, but in most cases, ~1.1V is enough.

you have to set an xmp profile on the cpu in the bios menu, which in turn overclocks the cpu, which allows and sets the ram to be overclocked to the specified xmp profile.

example, my cpu overclocks from 3.6ghz to 4ghz and the ram gets overclocked to 3000mhz, all through the xmp setting.

You specifically stated that it overclocks the CPU, that's the issue. It's a configuration-specific instance, but yet you spoke of it like it's a consistent fact for more than one configuration. Like I said, I've never seen this happen in the numerous configurations I've had and seen, and I can find literally zero record of this anywhere else. And I didn't join the thread just to respond to you, I was already here before you, look at comment #1.

AI Tweaker (bios menu tab under advanced mode)

i manually set "sync all cores"..

i also set the RAM speed to 3000

then i set AI Overclock Tuner to XMP (this setting wont show up unless you have xmp enabled on the motherboard, by flipping the xmp switch).


it auto sets everything below...


- XMP DDR4-3000 15-16-16-35-1.35V

- cpu strap 125MHz

- BCLK 125.0

- core ratio limit 32

- min and max cpu cache ratio 25

everything else in that menu stays at "auto"

w/e else it changes (like voltages/ect..) in other areas (not in the same menu), im not sure, never bothered to look.

but, needless to say, my CPU gets pushed from 3.6GHz (base clock) to 4GHz and the RAM to 3000MHz

thats whats killing it

most you can do is about a 5-6mhz increase (105-106mhz) before killing the cpu
