In BIOS maximum dram frequency option is 1600mhz

[lasha.gabashvili]

Hello, today I bought a brand new 2x4gb Ripjaws ddr3 1866mhz but here is the thing when I headed to BIOS the maximum dram frequency option I saw there was 1600 but my mobo says it supports even 2400mhz... here is the link - https://imgur.com/a/k90GR8d

my mobo is ZH77A-G43 and cpu is i7-3770

That's strange. Do you have an option to enable XMP profiles on that board? I would expect you should..... and the 1866MHz should be an existing XMP profile on the chips....

 

[lasha.gabashvili]

As you see in the picture there is actually enabled and it's 1866mhz but still everything like speccy cpu-z and even bios shows it's 1600mhz

 

[Barty1884]

Ah, I didn't see that.

With XMP at 1866MHz and the DRAM set to "auto", it shows as 1600MHz?

Very strange. The only requirement for >1333MHz is a 22nm chip, which the 3570 is.

Do you have the latest BIOS installed? 1.A or 1.9?

 

[lasha.gabashvili]

1.10

 

[Barty1884]

Unless that's another name for the one denoted "1.A"... there is no 1.10 I can find for that board?

I mean yeah I have installed that BIOS 1 months ago it's just it shows v1.10 in msinfo32

Then honestly, I have no idea. The higher speeds might be limited to unlocked "K" CPUs as technically, >1333/1600MHz is an overclock. But usually that limitation is only for speeds >1866MHz.

Helped someone with a similar problem, maybe same board? See if it helps at all. Towards the end of thread if you dont want to read it all.

I mean that's what I thought at first place but that's not about cpu there is no limitation for mobo it must still show frequencies and if cpu doesn't support it, it will start crashes but unless that mobo must allow you to increase the frequency

Dude not only the mobo but even the rams are the same, okay lemme try it.

Not always the case; the board can detect what CPU is installed - and in some instances (especially Sandy/Ivy bridge era), options only present that are available with the CPU installed.

Reflashed the BIOS still nothing :X

 

[boju]

Try load bios defaults after a reflash and clear cmos afterwards.

 

[boju]

Im not familiar with this board's bios layout so not sure what options it gives if configuring ram speed manually (not enable xmp)

 

[lasha.gabashvili]

In dram frequency options there is no higher frequency than 1600

 

[boju]

Im not sure bud. If it is possible, there may be a setting overlooked.

I know it's annoying trying to understand why it ain't working albeit the difference between 1600 and 1866 isn't much. I do get the frustration.

If you can't increase the frequency, lower/tighten the timings. Should easily make up for the less frequency.

As already mentioned above, you likely need a K cpu to be a able to use higher RAM speed.
Comparing to 8th gen Intel CPUs. DDR4 stock speed is 2133MHz, the I5-8400 can run them at 2666MHz but you need a K cpu to go higher, regardless of which motherboard you have.
