Predator PO3-650 Upgrades. Looking to get a NH-U9S unless anyone has any better recommendations.

Good Evening

Hoping someone can help me out with a couple of upgrades I'm looking to carry out on my

Predator PO3-650

From reading the forum my 1st upgrade of CPU cooling is sorted , I'm looking to get a NH-U9S unless anyone has any better recommendations.

Where if struggling is the RAM , my stock system has 16GB (2x8) Adata DDR5-4800 AO2V48UC8W1-BHLS. Im looking to double this or go to 64GB however i cant find any of the ram in my system or listed on this forum in stock for sale. Has anyone got any suggestion on RAM that will work with my PC?

Many thanks in advance for any advice.

Before you upgrade the RAM, make sure that you have the PO3-650 desktops bios updated to its last version R01-A4, as this bios fixes the Intel cpu problems by updating the “INTEL Microcode 0x12B update for the Intel 13th and 14th Generation CPU issue” as it will also update RC and MRC version update which is a memory compatibility issues.

Then have a look at the Crucial RAM Guide for the Acer Predator Orion 3000 PO3-650 desktop, but DO NOT fit their suggested XMP or overclocked ram, only fit the DDR54800MT/s CL40 type ram that is suitable for the 13th Gen cpu like the i5-13400 or (F) model or i7-13700 or (F) model of the PO3-650 desktop, or the listed ram below that Acer has tested on this desktop. Good luck and hope this comprehensive memory guide for the Predator Orion 3000 PO3-650 desktop helps you out..

Below is the Acer memory specs guide for your desktop.

Use 4x 16GB DDR5-4800MT/s CL40 for 64GB type ram modules listed below and highlighted Acer RAM modules part numbers

Many thanks for your reply

Would the NH-U12S chromax.black be a better bet? ive seen people on the forum talk about both.

Regarding the ram , this is where i was stuck , all the acer ram module parts were seeming to be obsolete and out of stock everywhere in the uk .

Would getting 4x of the ram below look to work out

The NH-U12S has a bigger fan, so go to the Noctua link above and get the measurements of the bigger NH-U12S cooler and see if it will fit into the spaces of your PO3-640 desktop, as its pretty tight in there with the ram stick on one side, so make sure that it doesn't hit the ram, as the NH-U9S is a smaller fan cpu cooler and that is why I suggested that for the smaller PO3-640 as the NH-U12S is for the larger PO5-6xx and the PO7-6XX Predator desktops.

That Amazon link to that Crucial ram kit at 2x 16GB DDR5-4800MT/s CL40 type ram at USD $89.00 (is good value) and will fit and work 100% and perfectly with your PO3-640 desktop, you need to populate RAM DiMMS #'s 1 & 2, as shown above. Cheers and hope this helps you out.

I've fitted Corsair RAM with XMP/EXPO EDID support to Acer 650 works fine. Only use two sticks not four.

Also I'd recommend upgrading to a bigger case that will allow you to fit bigger HSF

A Phantom Spirit 120 EVO fits on the acer board no problem, just need a bigger case for it

The NH-U12S is enough larger that it is going to be a real tight fit, if it fits at all. With the PO3 models the better option is the 9, which fits nicely.
