Changing Voltages on RAM

[Theocll]

Hiya all,

 

I’ve got a very unstable computer at the moment and one of the fixes I’ve been recommended is raising or lowering the voltage on my RAM. The exact product label is F4-4000C18D-32GTRS. Any help to find a safe voltage to change it to would be great as I’m new to messing with voltages. 

The computer is unstable no matter what speed the RAM is which is why I’m thinking voltages might work. If you want more info on my problems you can check the other post or just ask! 
 

Thanks everyone!

Which CPU and motherboard do you have?

On their website, they say 1.4v, but for stability testing, you could try e.g. 1.43v, though with such high speed memory, you may need to raise more than just the memory voltage to achieve stability and depending on your CPU and motherboard, 4000 may just be unachievable.

The stock speed and voltage is 2133 at 1.2v, I would expect this to be stable no matter what. If it is NOT stable, then I would run memtest to confirm if the memory is just faulty and needs to be returned.

I have an i9-14900k and an rog strix z790-a d4

Memtest has been run multiple times and comes back clear so I don't think the memory is faulty. I'll try at 1.4-1.43v and see if there are any changes. Running at default speed without changing any settings in the bios which I imagine is 1.2v still presents with instability. My main suspicions are mobo, ram and storage, I'm just trying to eliminate as many variables as I can. Thanks all for getting back to me so quickly

There's a small chance of incompatibility with specific memory, but most likely if you are having issues at 2133 @ 1.2v and memtest is clear, then it is not the problem.

Rma rams

 

Even if it isnt defective and jedec does work return it anyways since xmp doesnt work and you are paying for that xmp, pretty stupid to pay for xmp only to have it not work and you have to manually tune anyways, only reason not to return it is if that is samsung bdie which i highly doubt looking at the primaries (18-22-22) but you can confirm with thaiphoon burner

 

 

If you want plug and play rams get 3200c16 or 3600c18 (3600c16 non bdie 16-19-19 etc. is a ripoff bin with next to no performance benifit btw)

 

If you want high speed high performance rams you can get hma82gu6djr8n in 2666-3200 bin (doesnt matter since its probs unbinned) and run at 4200-4500 gear 1 which seems to be what 13th and 14th gen is capable of, dual rank hynix 8gbit djr so extra performance from dual rank compared to most 16gb sticks and 32gb kits that are single rank, should be available both new or used, but if unavailable you can just look on the used market for a 3200c14 bdie kit

 

You cannot have both high performance and plug and play rams, thats just how it is with rams

I’ve made sure the memory is in the list of compatible ram on the mobo website so it should be fine.

Okay perfect I’ll keep this in mind and start looking at some non binned memory and have a look at typhoon burner.
