Xmp - rise in cpu temps ?

[scubasteve]

How do guys so i'll list of first
gigabyte aorus gaming 5 z370
trident z F4-3000C15D -16TZR

So went in and enabled XMP it gave me one profile when done i seem to see some increases in cpu temps is this normal ?
dose it not give you 2-3 different profiles ?

the min temps were usually low to mid 30s and high to say 50 now its 30's to 40 and have seen it hit mid 50s and up respectively

OK I was just about to jump in and say that because you are running RAM that fast on Intel the bus speed would have increased. Hence the temps. However, according to CPUZ there it is at 100mhz.

But ! when you then look at the other screen it says - FSB-DRAM 1:30

So I would imagine I am sort of wrong but right. It has raised something within the CPU which is causing it to get warmer.

Ed. What I mean is usually, IIRC you can run up to 2400mhz RAM on Intel without it needing to alter the BUS. However, over that and it has to. Which must be in a way I don't quite fully understand. I know that Intel have changed the way their CPUs work because it was so easy to OC the bus and clock them far higher before even if they were locked. If you go over a 103 or so BUS now on any Intel it will crash, unless it has an unlocked strap like X79..

so is it ok to leave it like that or should i tun it back to default settings ,, was wondering why it didnt give me the option (profile 2 or 3) in XMP to put it upto 2666MHz since that wouldn't require it to oc as i see in the mobo specs or am i chatting doo-da ?

No. At some point something deffo needs to increase, hence you are correct.

For 2666 you need to do it manually.

The Ram Controller is on the CPU. So if you use XMP you are basically overclocking the ram from spec. The controller has to work harder hence it gets warmer. Result whole CPU get's warmer. Especially if the volts for the ram are increased by the xmp profile.

OP you need to do some reading on overclocking.

Depending on the system using XMP can change a few things or a lot. Increased voltages lead to increased heat. Worse still auto settings for voltages can be quite high and more than is needed for the clockspeeds and timings used.

I can not help much as I don't use a 8700k/Z370 setup.
