that shows my cpu-z memory stats.
running dual channel 2400mhz 2x8 gb on laptop zephyrus GGA502DU,
but after checking on cpuz, dram frequency only shows running at 933mhz, barely go to 1200mhz at its full speed. when i first plug the ram i can notice performance improvement on my gaming, after the next day, i tried play the game and the game runs well for a few moment and then suddenly drop performance as i play on single channel again, i thought it should be something wrong with the RAM configuration.
any idea or solution for what should i do?

thankyou

1200mhz at full speed IS 2400mhz, because it is DOUBLE DATA RATE (DDR) memory. When CPU-Z shows 1200mhz, that IS 2400mhz. When it shows 1600mhz, that IS 3200mhz. And so on.

It is 100% correct. Many laptops run at lowered memory speeds when there is no demand, and then ramp up to full speed when there is a load. Your system is working normal.

Hi thanks for the reply, anyway i tried to get into the game ( dead by daylight) and with the same time also open cpu-z. It shows my dram frequency still on 933mhz.

It's probably not a CPU or memory heavy title. Try running Prime95, with AVX and AVX2 disabled. Choose the "Blend" option, as that is memory intensive. You could also run Realbench and select your full amount of installed memory on the stress test option.

So long as you see it go to 1200mhz at ANY point, it is running normally. HWinfo is a good choice for checking the memory status as well as your CPU and other vitals.

Well, i will try that. Thankyou alot. But yeah as you said it’s not not really heavy on cpu and gpu. But i noticed after sometimes playing the game. The performance (fps) slightly drop. Any idea about this? Even with the other games like rainbow six. I noticed performance drop after playing for a while.

Heat? That is the most likely reason.

Make sure you are not laying the laptop on ANYTHING other than a flat table while it is in use. Not on your legs while sitting (Pants can block the air intake vents), not on the bed (Blankets WILL block the intake vents), not on a pile of papers, nothing. Those vents MUST be completely unblocked and free of obstructions.

Obviously there are some other potential issues that might cause problems, but when it doesn't happen until you've been playing for a while, it's usually due to heat. Very common for laptops. They really are not the best choice for gaming.

Im putting in on a flat desk. Never experienced any frame drops before tho. After putting the ram sticks onto the dual channel i noticed i got like 30% performance improvement in gaming. But on the next day. I also got around that 30% improvement but then it drops after 10-15 min of gaming. ( drop to the point as like playing in single channel)

If there are any steps listed here that you have not already done, it would be advisable to do so if for no other reason than to be able to say you've already done it and eliminate that possibility.



First,

make sure your motherboard has the MOST recent BIOS version installed. If it does not, then update. This solves a high number of issues even in cases where the release that is newer than yours makes no mention of improving graphics card or other hardware compatibility. They do not list every change they have made when they post a new BIOS release.


Second,

go to the product page for your motherboard on the manufacturer website. Download and install the latest driver versions for the chipset, storage controllers, audio and network adapters. Do not skip installing a newer driver just because you think it is not relevant to the problem you are having. The drivers for one device can often affect ALL other devices and a questionable driver release can cause instability in the OS itself. They don't release new drivers just for fun. If there is a new driver release for a component, there is a good reason for it. The same goes for BIOS updates.


IF you have other hardware installed or attached to the system that are not a part of the systems covered by the motherboard drivers, then go to the support page for THAT component and check to see if there are newer drivers available for that as well. If there are, install them.


Third,

Make sure your memory is running at the correct advertised speed in the BIOS. This may require that you set the memory to run at the XMP profile settings. Also, make sure you have the memory installed in the correct slots and that they are running in dual channel which you can check by installing CPU-Z and checking the Memory and SPD tabs. For all modern motherboards that are dual channel memory architectures, from the last ten years at least, if you have two sticks installed they should be in the A2 (Called DDR4_1 on some boards) or B2 (Called DDR4_2 on some boards) which are ALWAYS the SECOND and FOURTH slots over from the CPU socket, counting TOWARDS the edge of the motherboard EXCEPT on boards that only have two memory slots total. In that case, if you have two modules it's not rocket science, but if you have only one, then install it in the A1 or DDR4_1 slot.



The last thing we want to look at,

for now anyhow, is the graphics card drivers. Regardless of whether you "already installed the newest drivers" for your graphics card or not, it is OFTEN a good idea to do a CLEAN install of the graphics card drivers. Just installing over the old drivers OR trying to use what Nvidia and AMD consider a clean install is not good enough and does not usually give the same result as using the Display Driver Uninstaller utility. This has a very high success rate and is always worth a shot.


If you have had both Nvidia and AMD cards installed at any point on that operating system then you will want to run the DDU twice. Once for the old card drivers (ie, Nvidia or AMD) and again for the currently installed graphics card drivers (ie, AMD or Nvidia). So if you had an Nvidia card at some point in the past, run it first for Nvidia and then after that is complete, run it again for AMD if you currently have an AMD card installed.
