Have you gone into the bios of your ge75 before?

 

Yes, many times. And i know where memory overclocking is done. Default ram setting and XMP1 show same memory settings as HyperX advertised. Just never fiddled there before. Just left ram on default.

 

Ok for now try setting it to 3600 cl20-20-20-44 at 1.35v

Btw can i see your default xmp timings?

 

2666 cl15-17-17-35 1.2v. I checked hyperx website about the Impact Sodimm and it states that maximum supported is 3200mhz

 

Yeah then it should do 3600 if not more at cl20/22

Try cl20 first then cl22 if it doesn't work. If that doesn't work try 3466 cl20

Btw for the timings, the last value should be 2x cl or 2x cl +2

Take a picture of your memory timings in the bios too. I need to take a look at the secondary timings as well.

Download thaiphoon burner and take a screenshot of your ram information.

 

I see, I’ll quote it too you when i get home. Working atm! Thanks for your help

 

Always happy to help

Btw, I downloaded Thaiphoon Burner and I dont understand a thing, how do i read my RAM on this software?

 

I get an error when i press read "Thaphoon Burner has not detected any SPD EEFPROM device."

 

That's strange. Try other guides on reading ram info with thaiphoon burner.

 

Why can't Thaiphoon Burner read SPD? The most probable reason for this issue is an unsupported SMBus Controller of your processor or chipset.

Maybe bacause my processor is so new i dno

 

I used command promt to check my memory and the partnumber is Kingston KHX2666C15S4/16G

all i could find, had to use aida

 

Can you scroll down and take a pic of that?

is this better?

 

I need to see what memory chips your ram is using.

Yours looks to be Sk Hynix ram but which type is it? There are many types and they will affect how much you can overclock.

checked Hwinfo now, hoping it gives you the info you need...

 

Can u make a aida memory benchmark with stock rams?
Also what the average clock speed at that gpu?

average cloc kspeed for my gpu when i game is 1650mhz.

 

U have tried to running at 3200mhz with stock timmings?

 

No, is that safe?

 

If boot and be stable at benchmarks and games with no errors yes

 

I have the same rams as yours on my GE75
HyperX Impact 32GB ( 2x16 GB) DDR4 2666MHz Kit memory module

I had raised the uncore voltage as suggested by the guys in the forum

QUOTE
To raise the uncore voltage go to:
Advanced > OverClocking Performance Menu > Uncore

Set Uncore Voltage Offset to 125.
Make sure Offset Prefix is set to " +".

Now go into Windows and set the System Agent for all your profiles in ThrottleStop to +125mV.
UNQUOTE

Then go to overclock RAM Settings in "Manual" mode and enter the following numbers

Memory Reference Clock 133
Memory Ratio 12
QCLK Odd Ratio Disabled
tCL 18
tRCD/tRP 21
tRAS 42
tCWL 18
tFAW 36
tREFI 12480
tRFC 560
tRRD_L 0
tRDD_S 0
tRTP 12
tWR 24
tWTR_L 0
tWTR_S 0
Memory Voltage 1.25V
NMode 2
DllBwEn [0] 0
DllBwEn [1] 1
DllBwEn [2] 2
DllBwEn [3] 2

That was worked for me with 3200 MHz and have an Absolute Latency 11.25 ns

Hope that helps you

 

Try stock timmings and make uncore +125
Trefi 52500 -trfc 570 and memory ratio x12.

 

Wait i have to overclock my CPU? I really dont want to do that, it runs quite hot as it is eve nwhe nudnervolted. Or is that uncore somethign else?

 

Uncore offset is the System Agent voltage that we have to give it 125 milli volts.
After you overclock the RAM you will have a bit of increase of the temperatures and this is normal

 

I dont use ThrottleStop, I have undervolted my CPU -90mv on INTEL XTU, has Uncore nothing to do with my CPU? The Uncore is for ram?

 

Uncore it's that feed the memory control and some other thinks at cpu.its not overclock but give more voltages to that thinks.
For me xtu its crap compare to throttlestop

 

I believe tt u cannot overclock your RAM without increase the voltage of the system Agent through BIOS and then at either throttlestop or XTU

 

U cant push more than -90? At what undervolt mv u get blue screen?

 

O damn before 1 week I gives a try to xtu just for see the bench score. I keep it only 15 minutes. When I changed some times my undervolt it got bug and undervolt doesnt effect. On hwinfo i had default voltages. Also every change at other thinks needed restart pc .lol

 

Thats why we are all using throttlestop

 

The bad is summer comming and temps goes up

 

Thank you so much! Ur ram overclock worked. However my cpu is running +10c. And I cant undervolt it further than -90mv, or is that different now that i increased Uncore?

 

After-90mv get blue screen? No uncore doesn't effect to core voltage.Also u tried stock timmings at 3200mhz?

 

Yes, I changed TDP readings of CPU to stop Power Limit Throttling, so AC Loadline and DC Loadline is at 5. I cant do more than -90mv. However before this change i couldnt do more than -100mv anyway. All other GE75 owner with i9-10980hk ive talked to reports the same undervolt limit.

 

I suggest use throttlestop and undervolt 125 mv the CPU Core and 125 mv the cache.
Those beauties need some modifications though such as making some openings underneath with a wire mess, plus somehow try to pick it up a bit ( 1 cm is enough) by putting a book or some custom made rubber feet.
Undervolt as above with 125 mv and use a laptop cooling pad.
Next thing is repasting CPU , GPU & VRams, but this is another story full of pain.
But NOT pain NOT gain in MSI Laptops

 

Try ur stock timmings with 3200mhz.its way faster. Also really what ur temps of that cpu at gaming and benchmarks? And what clock speed its stable? Haha many questions

 

On 4.5 ghz it reaches 90c while gaming Apex Legends, however on 4.2ghz it reaches 80c max. I could benchmark Firestrike with 4.7ghz without it reaching 90c, but Timespy on 4.6ghz reached 94c.

4.2ghz seems to be the best for temperatures. I have gamed on 4.5ghz but cpu is 80-88c all the time which i personally dont like

 

I have repasted with Kryonaut, and -125mv is not stable

 

Cannot help you with those 10th gen CPUs. Mine is the "legendary" 8750H.

 

ANyway, thanks for your awesome ram overclock guide <3

 

I have tried with mine but no success. Thats why I suggested the above settings since they are working for me. Do you have any other suggestions for better timings? Glad to hear

 

Glad tt I helped you. .

 

Try 17 17 17 39

That I use now and it's awesome stable on my gskills

 

What about tREFI and tRFC? I use 12480 & 560 respectivelly

I use 54500 and 520.and cr1.if work cr2 u can try cr1
