Are those two ram sticks compatible? (HX424C15FB/8 and HX424C15FB2/8) kernel-power error

[miguelcarvalho000]

Hello, I bought a PC with 8g of ram (HX424C15FB/8) and later i upgrade to 16g and i bought this one HXC15F424B2/8. Sometimes i get a kernel-power error and i already search and test some things and i think the ram is the problem, so I i want to know if those two ram sticks are compatible?

It's for this exact reason why we suggest buying a ram kit when going for a ram upgrade. Mixing and matching two different sticks of ram or even kits tend to give you errors or an unstable system. The glaring issue is that one ram stick is single rank while the other is dual rank. You should have two identical sticks of ram but then again that isn't a guarantee outside of a ram kit(which are binned from the factory to work in tandem).

no since this one have a fastest trfc time response http://www.kingston.com/datasheets/hx424c15fb_8.pdf that could a port of power kernel error .

can you confirm what scout_03 said?

Are you sure about that? Because that and the fact that one is single and the other is dual rank is the only difference between them, so that can cause me the kernel power error or can be like my psu?

 

[scout_03]

compare both and see also check if the single is on the support list of your motherboard .

don't know what to do but thanks

 

[scout_03]

i did check motherboard compatibility and only the one from first link is on support list that you could use alone or in 2 or 4 of the ram slot so that could be the second on that give error .

can you send me the link of the list please?

Manufacturer tested compatible memory list is here.

Module HX424C15FB/8 is listed, but module HX424C15FB2/8 is not listed. However, an unlisted module doesn't necessarily mean that it is not compatible, because that particular module may not have been tested (yet).

As mentioned above, mixing individual modules is not really a good idea as there is a risk of inter-module incompatibility. Ideally all memory modules used should come from the same (dual channel) kit, as the modules have been tested for compatibility by the manufacturer.

You could try raising DRAM Voltage in BIOS by 0.05 V (but don't exceed 1.35 V), that might help to make the two individual to work together compatibly. But in this case it is less likely to work, particularly as one module is single rank, and the other module is dual rank. Mixing single and dual rank memory modules can cause problems.

Options -

1) Ideally get a 2 x 8 GB dual channel kit to replace the existing memory. The two modules have been tested for and guaranteed to be compatible.

2) Get another module (HX424C15FB/8) to try with the existing HX424C15FB/8 module. But note that even same model individual modules may not necessarily work together because of variations in module characteristics. So be prepared to try some other HX424C15FB/8 modules until a compatible module combination is found.

but before i buy another module i just want to make sure that the kernel power error is for sure because of the mixing rams

Try this link - https://www.msi.com/Motherboard/support/B250M-BAZOOKA.html

Then click on "Compatibility" on left side of page.

Then click on "Memory Support".

but do you think the cause of the problem is the really the ram?

 

[brispuss]

It appears that the memory modules (incompatibility) are the cause of the issue.

This "Kernel Power" error didn't occur until the second memory module was installed, correct? If so, then it seems logical the additional of the other memory module (with different characteristics) started the issue.

Check wether it's running on same 2133 or 2400 MHz. I suppose both slots should run on same frequency and do not increase the frequency beyond CPUs stability. Must also not overclock CPU unless checked or guided by an expert and also the voltage must be 1.2
