Bios X.m.p
Hennie Jaffe
First, I'd like to mention all drivers and BIOS are up to date (1.0.1). I have recently purchased two Aurora R8's (built the same except for Windows as one has Pro and one has Home, I will list at the end) which came with the stock DDR4 RAM. One of the two R8's arrived first and I immediately put in 2 X 16GB of Kingston HyperX Fury DDR4 2666MHz (into slots 1 + 3) which obviously supports Intel XMP. I was able to go into the bios and simply "enable XMP memory". I have even added a 3rd 16GB (into slot 2) stick the same memory/brand and Intel XMP is still enabled.
The second Aurora R8 arrives and I do the same procedure, update drivers, bios, windows updates, etc. I swap out the stock DDR4 2666MHz memory for three sticks of the same Kingston HyperX Fury DDR4 2666MHz and turn the computer back on. It's just a black screen. I eventually figure out it via reading forums it's a memory issue and I begin thinking the memory is faulty but I want to test it first. I leave one 16GB HyperX Fury in Slot 1 and turn the computer on, it states there is a memory change, I click continue, it boots into Windows and everything works. I restart and it still will not let me enable "XMP memory". I keep checking each memory stick individually in Slot 1 and each time the computer boots correctly. So, I then go add another stick into Slot 3 and the computer boots up to tell me the memory config has changed. I click continue and onto Windows we go. Still the BIOS will not let me enable Intel XMP. So, I then try to add 3rd Kingston HyperX stick back into slot 4 this time and same thing when I reboot - black screen and restart. I turned the computer and then I go and take a Kingston HyperX RAM stick out of the other Aurora R8 and stick one in slot 2. I now have all 4 RAM banks filled with 16GB Kingston HyperX 2666MHz sticks. I turn the computer back and get the message that the RAM amount has changed. Great! However, when I then restart I still cannot enable XMP. Why?! :) On the first R8, which now has 2 X Fury HyperX 2666MHz sticks in slots 1 + 3 I can enable/disable at my leisure. There is no difference between these computers. Can someone please offer some guidance?
The only difference between the two is R8 #1 has Windows 10 Home and R8 #2 has Windows 10 Pro regardless before I upgraded to Pro on R8 I could not enable XMP as all the steps mentioned above pre-date the upgrade to Windows Pro. :)
(4) For RAM sticks not purchased as a matched set, different manufacturing revision numbers may impact compatibility among RAM sticks sold even by the same manufacturer - Kingston can tell you, based on the manufacturing numbers on your RAM, if the sticks are essentially "identical."
I think Kingston HyperX Fury DDR4 2666MHz just does not have XMP mode. They would run at 1.2V as the stock memory modules. If you get HyperX Fury DDR4 3200MHz, you can go to BIOS and enable XMP for sure, the memory will run at 1.35V.
The entire Kingston HyperX Fury retail lineup comes with 2 canned extreme memory profiles (XMP1 and XMP2) ready to be selected. If it cannot be selected in BIOS the problem is due to a reason other than XMP profiles not being there. The aurora is notoriously picky with RAM so it doesn't surprise me to read from the OP that the exact same RAM works with XMP enabled in one R8, and doesn't work with XMP enabled in a different R8 with the same bios version.
This is not correct. XMP can be selected even if you have a locked CPU. I have happily run both HyperX XMP profiles with a locked 8700 in an Alienware Aurora. RAM overclocking is entirely different from a CPU overclocking. The K means the CPU core multiplier is unlocked and that has nothing to do with the RAM being locked/unlocked. The XMP profiles are canned settings in the RAM set by the RAM manufacturer and usually selected by the user in BIOs.
Thanks for the clarification. I hope you are right. I am about to do some upgrade to my R8 system with a I9-9900 and some HyperX CL16 3200 MHz ram. I will see if the new memory can have XMP profile activated.
That's funny I installed hyperx 3200 XMP Ram 64 gigs when I first installed mine I turned on the computer had a black screen. I then turned it off with the power button and then turned it back on and it was fine XMP enabled itself when I check the BIOS it was already enabled XMP one and in the Alienware Command Center it showed 3200 megahertz. I don't know what kind of ram you installed but the one that I installed said Intel XMP right on the ram Packaging
I installed new RAM today. First boot was not successful. I got an all black screen with the power button flashing amber twice (service manual says that means RAM error or no RAM installed). I then powered off my R8 by pressing and holding the power button, and powered it on again moment later. I got the same black screen, but this time I pressed F2 to access BIOS, which was immediately on and displayed correct RAM info. XMP profile can be loaded there. From there I was able to save the BIOS settings and get the computer to work normally.
On top of that I can no longer set the cpu multiplier above 38x. If I try to set it anything above 38x it reverts to 38 as soon as I move the cursor to a new entry field. No OS OC utilities see any multiple above 38 for the cpu.
If your eager to know if you can write to the bios region with fpt try to write back the dump of the bios region you just created (recommend non windows- version - DOS bootable usb stick - for dumping and flashing/writing):
fpt.exe -bios -f biosreg.bin
On researching i found that a LOT of customers after buying found that HP BIOS installed does not even support or has an option to enable XMP profile advertised for the RAM.
I have not come across a HP PC with BIOS overclocking options. You need this to use XMP or tweak processor timings and voltages. Some Omen PCs can run at 2400 MHz instead of 2133 speed. Maybe this PC will do XMP at higher speeds if HP is advertising this option.
most OEM sell systems that prevent overclocking of cpu's and ram since they do not want all of the service/warranty calls from people who try overclocking and end up with non working or unstable systems
laptops are even more of a issue due to the limited thermal headroom, the HP specs for your model laptop list 32 GB DDR4-2800 SDRAM (2 x 16 GB) supporting Intel XMP, however that does not mean that you (the user) can change the memory settings all it means is that the system bios will see memory that is 2800 capable and apply the settings automaticly
Same issue here, P03-640 running R01-B0 BIOS and XMP is greyed out -- no ability to enable/disable, even after setting a supervisor password. RAM installed is XMP compatible etc. Baffling, and frustrating!
I'm sure Acer staff have access to these forums so hopefully take the feedback into account and release bios updates to enable XMP profiles, because until then there's currently no solution to the issue.
Yanno i have to be honest with you after watching about a dozen YouTube videos and reading many articles about it all from different gamers and people in the business it's basically BS Ya only get about 5-10 fps increase and it isn't good to overclock things, they say people are so consumed with over clocking they overlook the basics to improve their pc like what you did NeoGeo it's a perfect example. look at that score and nothing on your computer is over clocked right?
At this point it's as much principle too at this point, XMP is supported and *should be working* on these machines but isn't for whatever reason -- Acer could and should be doing more to acknowledge this is a problem and push out a fix? Instead, I've paid for RAM that is capable of almost 1GHz additional frequency and my XMP-capable mobo doesn't want to play ball, I'm stuck with RAM running at a significantly lower frequency.
Yea that's just stock settings on benchmark, i actually tried an overclocked and got a much higher score but overclocking adds extra heat on components and can affect the lifespan too, something to bear in mind.
I was raising this discussion. I think twelfth gen processors support xmp 3.0 with ddr5. The problem is that the po3-640 motherboard only supports ddr4. Perhaps, this is the reason why xmp profiles are not activated in the bios.
well from what i have seen-heard in YouTube videos and read it is overclocking and they even call it overclocking because i bought crucial ddr 4800 MHz and with XMP enabled on a MB that allows XMP you get 5200 MHz and Acer limits us to 4400 MHz no matter what we use for whatever reason they decided this. if I'm wrong i stand corrected but i know what i have read and heard. and if Acer did not limit us to 4400 MHZ whatever ram we put in would run at the advertised MHZ no matter what without XMP enabled.
Intel XMP is an automated overclocking technology that enables motherboards to configure memory settings above and beyond the basic rated speeds of the PC industry, which are often significantly slower than the speeds that are actually achievable with a few clicks and compatible hardware.
I guess (reading back my post it's clear that Forums before Coffee is a bad idea) what I was getting at is XMP versus traditional overclocking (i.e. CPU, GPU overclocking) are a different kettle of fish entirely. XMP is viewed as far safer generally speaking.
In the same boat as everyone else with memory upgrade questions. I've read in another thread that ThisGuy got 32gb Corsair Vengance DDR5 running with XMP enabled at 5200 Mhz - but this is the only time I've read about XMP actually working...
well i do know now that what he is experiencing alot of users are with 4 sticks of ddr 5 memory and XMP enabled if he shut off xmp i bet his game would not crash there are videos all over youtube detailing this issue and it really hasnt been fixed yet properly many have found ways around it by undervolting the CPU etc. and im not 100% sure but its not only acer, dell and hp that do this any big name brand manufacturer limits you. its called pre-built proprietary components OEM vs pre-built SI-system integraters-cyberpower-ibuypower-skytech the list goes on and on but you get the idea, ive been doing research and its crazy how they limit us compared to the SI built gaming rigs. i never knew until just recently about this but i had a Cyberpower and a HP Omen 40L both got returned for the Acer Predator 5000 i currently own now. so im still researching it all to learn more, most probably know about this its just all new to me. and who knows maybe the cyberpower i had was a killer rig and i didnt know anything i had just got into gaming and bought it then returned it 30 days later for the HP Omen and after 30 days returned that for the Acer haha. no going back now only forward.
