@MrGeO - Yes, that is normal, click OK. It’s just message about you can’t write to SPD 
By default, if that is correct SPD for these modules, it should support C19 (19-19-19-43) @ 2666. But, this is normal, even for some kit with XMP of C15 @2666.
All looks OK to me, other than it not having an XMP profile (if it was supposed to, not all do)
My C16 @ 2666 kit with XMP profile has similar stock SPD to above/yours, slightly different of course, but same stock stuff like C18-18-18-38 in SPD vs what the XMP profile has
However, if you and @Vernnon have same kit, I would like to see his images/SPD dump too, so I can see about that 16GB vs 8GB thing I mentioned.
When you tested, did you set the vCCIO/vCCSA voltages I mentioned, and set dram voltage to 1.2 or above manually?
If yes, did you test 133 x 20? with loose timings, such as C18 (18-18-18-28) or C19 (19-19-19-38)
What is the stock speeds you see now? If 1333, lets confirm that ratio setting in the BIOS is direct and not doubled
Set 133 x 8 and boot, rest on auto, do you get 1066Mhz or 2133?
I never changed voltages, always at 1.20. I tested now 133x20 with C19 (19-19-19-38) but black screen only. Now i set 133x8 and other options in default, i attach you the results…

@Lost_N_BIOS this modules are mundial and if you enter in the kingston site, you can see that the modules has a datasheet that informing XPM profile:
https://www.kingston.com/dataSheets/HX426S15IB2_16.pdf
Look like mine bellow:
unfortunately @MrGeO bought fake modules, that is the true…
Don’t ask me about the differences in PN, but the memory is the same…
For C15, you may need to adjust vCCIO/vCCSA as I mentioned, this would be done automatically by XMP profile.
And ideally, since there is no XMP, you may need to slowly work your way down, there may be other subtimings being set too tight by auto (such as tRRD, tFAW, or tRFC)
Since there is no XMP, you really need to know about tweaking memory to get them to run tightly like that when setting it all manually yourself.
Thanks for the test, that confirms the ratio multi is direct and not doubled. So 133 x 20, or 100 x 26 both = 2666/2600Mhz
Can you boot 2400 both ways (133 x 18 or 100 x 24) with everything on auto? If not, then in auto, or whatever you can boot now, hit “Sensors” button at top of HWINFO
When window opens, scroll down to where you see vCore voltage and below that you will see vCCSA and DDR voltages, what does it show for both
* Edit - @Vernnon - You have SK Hynix Kingston, his are Samsung, may be made at different times, different batches etc. Serial # formatting at least looks similar, but part # missing in his modules, so that’s is not good.
But yeah none of this can tell for sure what is real/fake, only Kingston could confirm that. If you both are supposed to have same “Model” then yes, his should come with XMP too.
If you do not have same model, then nothing can/should be compared here because Kingston sells LOT of SKU’s, not all may be same quality/batch/binning, and not all may have XMP
He should probably speak to Kingston and see, send them SPD dump and the images he sent me at post #662
Does the reviews on the exact item # he purchased on ebay have a lot of negs, or mention fakes etc?
I didn’t try 133x18 or 100x24, but now i am on the last setup i had, 133x8…Is that the pictures you asked? (attached)
I will speak tomorrow with Kingston or Hyperx and see, i also wait 2nd response from seller. His first reaction was “Hi, dear friend. Sorry to hear the problem you reported, we got the item from HyperX, they said the item is high quality and A grade product, at this case, Can you provide us with pictures so that we can reflect to the supplier, and then help us return it, do you think it is ok? If you can use it, we will return you 10% as compensation. what do you think?
Or if you have any ideas please feel free to contact us. Sorry for any inconvenience. Best regards.”
Only a retard would believe this is true. 10% haha ok. I saw his reviews. He has 98.5% positive. On this ram he has 19 sales, and until now 6 good critics, i guess they didn’t realize yet…
But i saw negatives from past, where many speak for wrong/no genuine items, including some other rams.
@MrGeO - I did look at the images @ 664, thanks. It was set how we wanted to check (1066Mhz), and I replied about that…
BUT!!! I just noticed, BIOS setting IS half what you set, so not directly Double-Data speed setting!!! ie 133 x 8 = 2133Mhz actual (you see 1066 in CPU-z, double this = DDR / actual speed).
Sorry I missed that when I replied previously!!
So, you need to set the following >>
2400 >> 133 x 9 - Or - 100 x 12
2600/2666 >> 133 x 10 (=2666) - Or - 100 x 13 (=2600)
Set one of those, with loose timings first, then later once running you can test for stability and start lowering timings.
Yes, Deny 10% refund, if it’s fake, then you want 20-50% if you keep, or 100% refund!! Only 20-50% maybe, if you keep it, or 100% if they want it back
But yeah, up to you on this, I would not take 10% refund. I bet it may be OK though, not sure yet still. Does the listing show a “Model #”? If yes, as him why Model is blank/empty in the SPD? Kingston would not do that.
No the listing didn’t write any part number. But was clearly talking about a Hyperx Impact ram, nothing for replica or copy…
https://www.ebay.com/itm/32GB-2x-16GB-Hy…872.m2749.l2649
I opened dispute in Ebay and will not accept any return. It’s ilegal to ship non genuine. Already uploaded all images with evidence, will see the next days. About the Cas latency i don’t think nothing will work! I tried 18-18-18-38 or something like this you had told me but nothing…
I want to thank you for all your effort and time for me! I’ll write back when i have news.
@MrGeO - Ohh yes, if it’s supposed to be HyperX product it would for sure have proper model #, non-matching Serial #'s, AND it would have XMP profile too!
As for timings, those are irrelevant unless/until you set the correct multipliers for those higher speeds. Until post #668 I had been telling you incorrect multi’s that would have = speeds NO DDR4 kit for laptop would boot at (ie 4800-5200Mhz. 
)
Be sure to try what I mentioned at #668, no matter if you return those or not, then I’m sure they will be booting, at least with the looser timings (or auto)

@saltinbank - Wow, thanks for posting! Yes, that is a massive memory OC for laptop like this, very nice! 
Hopefully some of your mentioned tips can help MrGeO make some progress Sadly, I advised him wrong initially about ratio, and he started a memory return, so he may not get into testing before sorting that out first (unsure?)
His chips are Samsung though, if he keeps that kit. Unless it is 100% fake w/ fully faked out SPD, then who knows what IC’s without looking directly at them.
Hi guys,
Do you believe that it`s possible to unlock the PH315-52 max RAM size limitation of 32GB.
I realy would like to have 64GB to run my sdwan labs =)
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 32 GB

Thank-you
@elt - I can look and see if I can find it, but the limitation may be due to chipset not something they artificially limited to 64GB.
Did you already try 64Gb and it still shows 32GB? If not, try it and it may work
* Edit - Sorry, I looked, and I can’t see anything similar to what I know for changing limit from 64GG to 128GB, so not sure it’s possible here.
If it is, maybe @dsanke could help to locate the edit? Random BIOS region is here post #649 if you have time to look and see for us, thanks
@Lost_N_BIOS I believe the DMI reported max DRAM size is fake.
Just try 32GB *2 first, and see what happen.
@dsanke - I thought that, and suggested it as well, and maybe thought I found maybe I found memory limits (lack of) in SiInitPreMemFsp @ routine 6FABF, but not sure at all.
I was thinking, could the reason i couldn’t get above 2666mhz with my ram. Is it because of my Cpu? Cause my laptop is running an i5 9300h so could it be the cpu doesn’t allow a higher memory speed?
@Lost_N_BIOS
Actually Acer says the RAM expansion limits are 32GB but Intel says the CPU limitation are 128GB.
So I thought it could be something set in BIOS.
I didn`t try to use 64GB or more yet, the RAM is a quit expansive.
Would be great to know if someone had tried to use more RAM than Acer says as the limit.
