Buyer Beware: 3200MHz nominal speeds may require XMP

Unfortunately, I can't give help to your request: however, I can tell you that all/nearly all RAM with advertised speeds higher than 2666Hz will not run higher than that out of the box. Many motherboards these days only "officially" support 2666Hz memory. However, on XMP enabled, your RAM is guaranteed to reach advertised speeds.

Having the same issue. Its not that the Ballistix dont have XMP. Seems the issue is in BIOS.

Correct. The problem is that the Ballistix will ONLY reach 3200MHz **with** XMP;
*AND* the current BIOS does NOT support XMP.

Kingston is by far a much more worse Sodimm. They just got managed to install a chip which makes the OC automatically.

Do you have factual support for either of these claims?

Since Crucial doesn't publish the profiles their support,
it's difficult to know, if their lower CAS latency is actually
valid at **all** speeds, or only at 2666MHz.
I suppose CPU-Z will list what it finds, I just never run it
with those sticks in the laptop. Have you?

The other bit about an OC chip in the Fury sounds a lot
like unsubstantiated speculation, but if you have facts,
please share!

Crucial seems to need a Bios unlock.

I'm not sure about "unlock", but those modules definitely need
XMP support to run at their advertised speed...

Fury has CAS 20!

Indeed. And, the original Samsung RAM has CL 22. So, what?
Is the Ballistix running at 2666MHz with CL16 really better
than the Fury running at 3200MHz with CL20?

I don't actually know. I'm not sure how the different speeds
play together with the different latencies. My understanding
stops at comparing speed/latency combos when either one
or the other is fixed (i.e. at the same speed, a lower latency
is better; and, similarly at the same latency a higher speed
is better). I don't have the slightest clue what applies above.

Does anyone have a unlocked BIOS for XMP profiles?

Another thread here claims that the older BIOS has XMP support.
You _may_ be able to downgrade, if that floats your boat.

i had issues with kingston in my older razer blade studio. kingston is OC by chip to get to 3200. So i doubt your laptop is running all the time at 3200mhz. Another point is the latency. By installing the ballistix i could see how fast the booting took place. at least 2 sec less.

But i also send those back to order furies. i will soon see which is better. i had before both the samsung and also crucial 64gb at 2666hz inside. and none was so fast as the ballistix in booting.

.Z4x.
Interesting... I haven't noticed a significant difference in booting speed between the different RAM options.
BUT, then again, I'd have to use a stop watch to recognize a two-second speed-up... :wink_:

I dont shut off my laptop. Never. So i can see the difference. I also used a stop watch to be sure. Yes it worked faster. But maybe not in Adobe PS

my new RAM arrived today and seems it works at 3200mhz. Seems the CAS is not the same.

HyperX/Kingston Fury should run @ CAS 20 for 3200 Mhz. Best I have seen for 1.25V RAM.

I know mate. That's exactly what I wrote above. It's slower in terms of latency.

At least it works on default JEDEC....

Iman.Nia
Latency is also important. So razer owner are forced to choose between mhz or latency. Thats not an option.

There are only a few laptops out there which can run 1.35V XMP profiles (you can see the reviews for Ballistix)

I went to for the middle ground which is 2933 MHz with a latency of CL17...from online ram calculators, it is marginally the fastest between 2666 CL16 and 3200 CL20...

Did anyone install additional Ram Heat Sink to their Ram? I did. Wondering if it makes any sense
After removing those labels on the m.2 nvme i can see dropping temps of about 4 degrees as the thermal pads have direkt contact now

Did not put one on mine (though I bought some from Aliexpress). Thought the blowers are enough to keep them happy and cool.
