Question How to identifies kits of RAMs that will run at their advertised speeds WITHOUT requiring XMP or any other BIOS option tweak/change

[thereisnotry]

Want to upgrade a friend RAM to a 16GB kit which is the limit on his board but read that some kits require a specific BIOS option to run at the advertised speeds, which this board doesn't have

The BIOS is extremely limited and there are no option to adjust/modify anything Ram related whatsoever.

All the specs can be found on the official HP page, found here: https://support.hp.com/us-en/produc...ies/6886619/model/7105493/document/c04336643/
The only difference is that the system now has a 1060 gpu instead of the r7 240 and a SSD.

As the title states, the question is: How to identifies kits of RAMs that will run at their advertised speeds WITHOUT requiring XMP or any other BIOS option tweak/change

Will this kit: https://www.amazon.com/dp/B00G1H3UUI/ref=cm_sw_em_r_mt_dp_U_pDyiDbJG924W2 or this one: https://www.amazon.com/dp/B009V50HV2/ref=cm_sw_em_r_mt_dp_U_yGyiDb2QTQ4RZ run at the 1600mhz advertised speed without any BIOS tweak? If not, would appreciate if anyone pointed me in the right direction.

Thanks a lot for your help.

If there's no option to enable XMP, then ram will run at 1600mhz max (ram module still has too support 1600mhz).

Thank you for your response but my concern is with RAM kits that advertise 1600mhz but don't mention that xmp or other bios option are required to to actually reach that and will operate at 1333 instead if those options aren't available like in our case. I came across this issue when browsing for a kit to buy and actually seeing someone run into this scenario where he bought a 1600mhz kit but couldn't run it at that speed because of the lack of option in the BIOS

Again, I'm interested in figuring out how to identify which kits can cause the problem mentioned above and which kits will run at 1600mhz no matter what, whether there's xmp option in the BIOS or not.

Thanks again for your help.

Practically all RAM in QVL list will do that. It is by no means definite list but those are ones tested with that MB. Other way would be to look at most compatible and fastest RAM from QVL and see if you can find other RAM to fit those specs.
XMP is just a suggestion to BIOS to set RAM for given frequency, latency, voltage etc. You can look at those values and set RAM manually to match them even without BIOS having XMP option.

That would be on Sandy Bridge or older cpu. Sandy bridge supports 1333mhz and 1600mhz would require manual OC or XMP.

Your cpu is Haswell generation and doesn't require XMP for 1600mhz ram.

Go to a ram vendor web site like Kingston or crucial and access their ram selection app.
Enter your motherboard and you will get a list of supported kits.

sometimes they not only require a specific BIOS but a specific model of motherboard. like for an intel CPU you may need a board with a Z chipset to get the max advertised speeds. some advertised speeds do require you to enable XMP

also if that PC is a prebuilt brand name PC it is likely you won't get the advertised speeds of any RAM because brand name PC's are not upgrade friendly
