2933/3200 JEDEC 32GB 2x16GB Kit [NOT SODIMM]

Hi Guys
I've got a Acer pre-built system around that unfortunately does not support XMP (don't get me started, it's greyed out in BIOS). It's based around a 10700K so officially can support 2933MHz, and unofficially much higher.

Rather than having to worry about warranty issues by replacing the motherboard, I was hoping someone might know of some memory kits that have a JEDEC speed of 2933/3200/3600MHz, so I don't have to rely on XMP profiles I cannot use; and have the memory default back to something silly like 2133 or 2400MHz, but should instead just run at the fastest JEDEC profile the motherboard/CPU will allow.

Anyone? I know Kingston have done some SODIMMs with 3200MHZ JEDEC, but am looking for desktop memory, and looks like the desktop DIMMs rely on XMP. If the timings are not terrible that'd be nice too, albeit its for an Intel based system so shouldn't matter so much.

Most of the decent RAM I can see seems to rely on XMP and higher voltages to run at decent speed!

Figured that'd be the case. No worries, at least I know it's possible to find; and if its value it shouldn't be rediculously priced.

I'll take terrible timings over the RAM running at 2133/2400MHz, especially with Intel

If anyone has any particular part numbers they think I should check, would be much appreciated.

Cheers,
The top lines are the ones I had been looking at already; the stuff that comes with the system as a 16GB set doesn't seem purchasable directly, but as you say there are alternatives.

PPS I understand 3200 CL 20 is possible via JEDEC. If anyone can find any of this, please do list a kit number

I've found Crucial 32GB (16x2) 3200 CL22 JEDEC Dual Rank 1.2V for £150 for 32GB [Kingston seems to be around £200), I'd love to know if there's actually any 3200CL20 JEDEC ram in actual manufacture and not just a spec officially approved by JEDEC.

I am hoping to temporarily test some XMP RAM just to ensure that the XMP on this motherboard is indeed disabled; which I believe it is, but it'd be a waste if I could get a better performing kit for the same price or less; simply due to misunderstanding.

Thanks both. Ideally I'd be looking at 16gb dual rank DIMMs so the above 8GB ones aren't ideal but will bear in mind.

Acer have locked the bios down pretty heavily which is a real shame as the machine has many good points, especially at the price I paid.

Really not sure why they've locked down XMP to be honest.

Yes, I have [to no avail thus far], I've also asked if resizeable bar support is coming, as frankly I also think that should be a done thing.
I have been told that [rebar] is coming August; but as far as I can see Acer is very slow with BIOS updates/support, and unfortunately their CS responsiveness gives much to be desired.

What is frustrating is the product page mentions XMP [and also Overclocking] in one place and then it is never mentioned again; I am loathe to buy XMP requiring RAM only for it to be forced to use poor, slow JEDEC settings.
"With support for dual-channel DDR4 configurations (up to 64GB XMP), a buffet of dual, high-speed storage, Intel’s Z490 chipset and up to a 10th Gen Intel® Core™ i9 Processor – this beast gives you a taste of what a powerful system is truly capable of. "

I am hoping to borrow a stick of RAM to test this out though before I buy anything, if XMP DOES work, then bonus, if it doesn't, 3200 JEDEC kit it is. I am REALLY hoping XMP is greyed out in the motherboard as the included RAM doesn't support it. If this is the case; then I will let them off, but for a Z490, the lack of customisation and control in BIOS is very poor, given the market they are targetting with this grade of machine.

Obviously I'd prefer self builds, but components have not been...ideal...this last year or so, and managed to get this machine at a very reasonable price.

Well was able to borrow some RAM off my brother just now and turns out the info I was given previously was wrong, the machine does in fact support xmp. It doesn't allow you to pick a particular XMP profile but it does at least allow you to activate XMP when compatible RAM is installed, and SEEMS to pick the fastest profile.

Either way this makes my life easier, will allow me to pick a higher performance kit, and potentially cost me less too!

Still think the BIOS is a bit of a joke, but at least a bit happier!

Yep.
As a small aside I actually got another response from Acer this morning advising they CAN unlock the BIOS but they'd want £72 a machine to do it. FML...
