It doesnt work for me. My system wont even boot when I set 3000 mhz and 1.4 volt let alone 1.39, 1.38, 1.37, 1.36, 1.35 volt. I cant even go 2600 mhz 😢 2400 mhz is max. It just keeps on rebooting and after 3 reboots I can go to bios. I dont understand. I have the same brand and model and same 64GB kit as you 4 x 16GB. Do i have to increase some other voltage in bios besides ram voltage? System agent? I/O? Please help me. Thx.

Easy overclock guide... Put in the timings that are labeled on your sticks then set your ram voltage to 1.40 then go from 2400 to 3000 simple!

@@daddyalpha2648 this is only from 2400MHz to 3000MHz. Anything Lower than 2400MHz won’t work. Also your motherboard has to have overclock compatibility. My ram I tested on was 2666MHz to 3000MHz at 1.38 or 1.40 I forgot I don’t have them anymore.

I was try to oc too many times my ram, and this video show how doing better and works. Thanks mate

[@elpepito957]

Just a quick disclaimer for anybody looking to do the same, please also check the voltages applied on "auto" by the motherboard. If you look at 3:19 you can see that on auto the board put 1,336V. It is way out of the normal operating range for the VCCIO (and VSA) which should be at 1,25V maximum pour 24/7 use. It is actually dangerous to run our CPU with a VCCIO that high for long periods of time as it could damage the CPU's IMC (Integrated Memory Controller). Best to manually set it to 1,25V max. Hope it's helps.

[@MartinGuder]

Edit: I searched for some minutes and I think you are a bit mislead concerning VCCIO and VCCSA. Since 2nd gen i-Processors, this voltage is used for feeding all input/output (I/O) pins of the CPU, EXCEPT memory-related pins. On CPUs that have this voltage, it is also used to feed the thermal control bus. VCCSA (System Agent) on the other hand was before 2nd gen known as VTT. This feeds the integrated memory controller, PCIe controller and graphics engine of the CPU. Still thanks for the hint. Will try to lower those voltages if possible.

[@elpepito957]

@@MartinGuder Thanks for the reply, i was referring to the max value given by overclockers and various guides that all state to keep within 1.25V max for good measure, like this guide => www.tweaktown.com/guides/8481/coffee-lake-overclocking-guide/index5.html. I can also speak from experience as I've just seen a coffee lake chip died and rma when applying too much voltage from DDR4 bench overclocking past 3800 that is. Again, a quick google search points out that 1.25v seems to be the consensus, I am looking for the der8auer video on ram overclocking but i can't find it. Auf wiedersehen

Žiga Vodnjov Frelih Usually you should not mix different RAM Dimms and also try to go dual channel.

[@paolotrenti5913]

Hi Martin, thanks for your tutorials. I'm planning to build Hackintosh/PC double boot like you, but, if I understand right, you are planning to upgrade to Vega 64 instead of the RX 580 and with a 1000 Watt PSU. My questions: what GPU you think is better to use to have best performance in gaming, Vega 64 or Nvidia 1080 Ti? Why Is not enough your actual 650 watt PSU for your future upgrading?

[@MartinGuder]

For high end performance Nvidia is the only way. You can wait for Vega 7, but still nobody knows the real world performance. Should be en par with a 2080, but who knows. The more performant GPUs, especially Vega, need more power. And before I run into errors because of a PSU, I just upgrade. 850 Watt should also be ok, maybe 750. But 650 will most probably cause some trouble. I just choose 1000 Watt to be future proof. ;)

[@RMX.Studio]

Forget about Nvidia Graphics card, if you want use the latest Mojave OS..

[@paolotrenti5913]

@Raimiky Yes sure, I'll be fine with High Sierra in that case. Anyway for now got Vega 64, 1080 ti too difficult to find and too expensive.

Definitely too expensive. I'm curious, if the Vega VII works for Hackintoshs some time soon.

[@classic_91]

is it save to set voltag of the dram at 1.27 @ 3600 ??

I read, that 1.35 V should be the maximum. Your BIOS usually indicates dangerous voltages with red and purple (at least ASUS mobos).

Valid question, but if you don't overdo it, it should be fine. Hard to say, if hardware starts failing earlier because of generic overclocking. Extreme overclocking though will most probably shorten the life span.

[@MartinGuder]

X99 is probably different how it behaves with overclocking. At which post stage is it failing? Usually onboard status LED during post indicate, which stage fails. But from my experience. Also what CPU and clock are you running. Probably cross-check that with a X99 OC tutorial first.

Revert to default and try first the one change, then the other and see, what is causing the issue. Or: just try a higher core voltage in tge RAM first. Probably 1.35V already solves it.

Damn. Maybe then try increasing voltage in 0.05 V steps. Somebody in the comments said, that he uses the kit at 3200 MHz with voltage somewhere around 1.35v. That's even a better result than mine. So it really depends a bit on the production batch. Some are better than others. But overall don't be upset, because for everyday use cases it doesn't matter that much. For benchmarking it gives you some additional points, but you won't notice big differences, when you e.g. export videos. The few seconds benefit are not worth potential instabilities or huge efforts until you get a stable overclock.

i got my kingston hyperx 2666mhz able to get 3333mhz lol

ram overclock work good but dont do it on cpu it will break ur cpu really after you did few time my ohready broke yesterday so i just buy new 1 and put in
