Hi. i have some questions.

recently playing with my i7-10700k and manage to OC @ 5.2 all clock with 4000MHZ VengencePro.

My other friend also have the same and exact spec (mobo/ram/aio) but it manage to get @ 5.3 stable on 93c temp.

while mine will crash at 5.3.

Both are using stock termopaste (from Ryujin AIO)

The only difference between me and him is the PSU.

I am using Corsair SF600 while him using CM WME 650

So question is , does the PSU matter or he just got lucky with his Proc.

here is my CPU-z validatation : https://valid.x86.fr/j0vnxj

Any master @ sifu care to educate about this ?

Silicon lottery bruh. Meaning your friend got better quality cpu.

i guess so.. lucky him. thinking to delid but scared for warranty reason.

What the point 5.3ghz? 365 days running benchmark?

yes, your psu too weak for i7, i did'nt know about your gpu bout i7 10700k atleast more than 650w. you can run but and psu can give power , the lower psu like 600, more volatile the output voltage. need more info about pc, like gpu maybe your cpu running and your friend both gpu and cpu are running. maybe.

Nah, just education purposes, just want to know the limits and then use it as normal. Its normal to have curiosity when using K version, and try OC.

Both GC are not installed. We try to avoid differences thus we only use the igpu.

So psu also give some variance and became a variable also for the oc result then.

Some asking me to check a current spike saying that irregular current at house also can make it diff.

try change psu with your friend and look the result, if same maybe you are unlucky.

100% unstable both...

According to guru3d stable at 5.1ghz with 1.5v
Idle 74w
Single thread load 116w
Multi thread load 248w
Watt per core at all core load 31w
Temperature at 67c on lcs
Depends PL2 short term maximum power draw for a processor

You saying your friend stable at 5.5ghz for how long? usually needed to be tested over 24 hour or week using benchmark like prime 95

From my personal experience try add more voltage hit the specific speed you needed optional fan directly blow vrm

Check cpu and system temperature slowly reduce voltage
Disabled cpu state 1 blah power saving mode

what do you mean ? PSU and current, or both me and my friend ?

mine stable at 5.2 @ 1.38v but my friend stable at 5.3 @ 1.38v

what makes me curious is mine cant get 5.3 at the same sitting as my friends.

in theory yes I can push it up with more voltage, but that is not the question at first.

Most of the time user will say stable specific target without bsod for how long? like your friend

Some circumstances even stable everytime turn on pc without bsod doesn't mean there are no bsod or hang after some gaming session
Bsod Can appear after long enough idle

Guru3d most reliable hardware review 1.5v stable at 5.1ghz you and your friend @1.38v possible your friend doesn't told whole story or just trolling with you

Edit , try run a firemark for good 30 minutes , make a comparison from your friend score

which b-mobo that can support OC and yet have great heat sink ?

b460 msi/asus/gigabyte etc ?

should i wait for b560 ?

or any recommended mobo for z490/z590/ msi/asus/gigabyte etc ?

1.5v? U gonna fried ur proc lol

Fried really? Is intel,they make a good processor, the only problem are long term which causing motherboard CPU behind leaving burn mark and shape change

Don't you remember story of socket 478? 1.65v no problem at all

apa ni..
some noob oc is it..
lol

the best is not using K to overclock.

The best is using F version to match K performance.
F no max turbo limit + BLK103MHz + The Right B460 Mobo.

that the best possible build. Not K CPU + Z490 mobo

with F + B460, you can save up to RM800!!!
for nearly same performance.

While you got extra RM800 to upgrade GPU.

thats got to be the most idiotic thing i ever heard..

SOS

Crazy Yeh... Intel want tax "Fanboy" more with the so called Z490 and K Series CPU.

ACTUALLY??? K and F is nearly identical products.
For 14nm arc is OVERUSED, and later gen of SKYLAKE reborn is nearly little overclock headroom...

The best PART?

Buying F. with the fake 65W TPD, F Series is as power hunger as K. when you remove limit on max turbo....
since we can OPT out the FAKE K Series Overclock too... ( less than 2% actual FPS gain in most case )

We can OPT out Z490 mobo with its ridiculous price.

*** if you gaming on 1440p...., u might even ignore i7...
Gaming on high res always let the System meet its GPU Bottleneck much earlier than CPU..

So, if you dont like i5, i7 F Series was the best choice.
