What is my ram speed?

CPU-Z says it is 1064mhz but can someone tell me what is the actual speed?

Messaggio originale di Bad_Motha:

It can try to set them via AUTO, but that doesn't mean its correct, based on your applied Frequency that's not even set to spec that the RAM was made to run at. So nothing on Auto can be deemed correct really. That is what the hell the XMP is for, it totally addresses any guess work, if the XMP does not work, you buy RAM that DOES WORK. What is this people do not get. Your RAM is now set wrong and will lead to instability and possible data corruptions and other OS issues.

The RAM was designed to run at 3000; it went out of the factory tested at that spec and thus has a certain timing sheet and voltage that goes with that.

2133 is just a chipset default for SPD, nothing more

It's only unstable if you:
1. have too low voltage
2. too high clockspeed
3. too low timings

Having lower clockspeed or higher timings won't make RAM unstable. It just will be slower.
But you can manually tweak these.

Any RAM that is advertised as 3000Mhz CL16, will run 2666Mhz CL15, maybe even CL14 with some tweaking with 1.35V and be stable.

You might want to try RAM overclocking yourself more. You don't quite yet seem to have sufficient experience about it.

If can't be bothered to change Mobo or RAM; then just apply whatever is highest but also stable; for example:

DRAM Freq = 2700 MHz
DRAM Timings = Auto for all of these entries
DRAM Voltage = 1.2V (if unstable or refuses to boot, change this to 1.35)

Then double check your CPU Multiplier and ensure CPU Clock is correct based on stock speed specs for installed CPU. As changing RAM settings might then change some CPU settings.

The voltage should honestly always be turned up to 1.35V when not running at 2133Mhz.
It won't affect the lifespan of them and won't create any considerable amount of extra heat.

As for timings, these are often stable all the way up to 3200Mhz if person wants to tweak them manually:

CL: 15 (CAS Latency)
tRCD: 15 (RAS to CAS Delay)
tRP: 15 (RAS Precharge)
tRAS: 35 (Cycle Time)
tRC: 50 (Row Refresh Cycle Time)
Command Rate: 1T

The names inside brackets are the full names and how they might be shown in the BIOS.

[Bad 💀 Motha]

No, even 2666 Mhz = 1.2V
Now at 2800 on most kits, yes we see it needs 1.35
Again since the RAM in question doesn't run at spec, just try a few simple changes like I suggestion. If fails to boot, force off the power and then wait 15 secs and power it on again. If somehow still fails to boot, power down and reset the cmos using jumper or shorting the cmos pins (refer to motherboard manual for this)
