Ddr5 Ram 4800 Vs 6000

[Karlyn Hemmerling]

Icannot reach any DDR5 Speeds above JEDEC 4800 40-40-40-82 and faced a lot strange errors. I know that 6000 is an OC and there is no guarantee to reach this speed. However, I have tested 5600 and 5200 profiles. This always leads to the errors described below.

But this is only the case since the latest BIOS version. With the delivered version, I could not even access the UEFI. When I try to increas the RAM Speed on this Board it will always be stuck when the "Pre memory System Agent initialization is started" and the RED CPU LED lights up. After a few seconds the systems reboots and everything start again.

In contrast, the Gigabyte board was so unstable that UEFI crashed when saving the setting and I was unable to flash the bios to the latest version. The update process froze and the board now no longer works.

Floppes, are you saying you are running two different memories?!? You should start by getting rid of one vendor's memory and trying only one. I have an older Gigabyte board and it has a Qflash button on the back that can be used to flash without a processor. Please read your manual and try that if you have it. Thanks and enjoy, John.

Thanks, Floppes. When you are running again, please post screenshots of Ryzen Master (RM) both Basic and Advanced mode running Cinebench R23. Please start with default setting before trying OCing. Post Event Log details for any errors and post the parts you have not reported, like cooler, Power supply,memory size etc. Thanks and enjoy, John.

Now I have a new issue, which is loosing all USB connectivity of my mouse and so on. The screen goes black and stays there for >1 minute. Sound in the background continous. After that I get the message that my graphics driver stopped working from the radeon app.

I know 7000-series can reach 95C, but when you have only 8-cores, a fairly capable air-cooler and are not running a stress test... How are you idle temps? Have you tried curve optimizer.. set negative 5 or negative 10, might be able to go even lower to reduce temp and increase performance.

Thanks, Floppes. There is a problem shown here where Basic view on one side says you are running PBO and the other Default. The Advanced mode indicates you are running PBO. Did you set PBO in the BIOS? Please do a Clear CMOS then set default settings. Do not OC anything. Then run your test (all default) and post the screenshots. Did you get all your AMD drivers from here? Enjoy, John.

no activated PBO for that run in the Bios, because my score was even lower without it. Compared to test results from outlets I am far below. I know that my RAM is running at JEDEC only, but is that impacting so much?

Moreover I noticed microlags in games like CS:GO and World of Warcraft, which really do not have high CPU load. I changed the internet provider using my mobile phone to exclude any network or network controller (Cabel and Wi-Fi) related issues.

Upgraded to AM5 7900X3D. XMP profiles no longer are selectable. DDR5-6000 timings must be manually entered, random system crashes, hangups and intermittent issues. Reduce memory timings below 5000 (I'm using DDR5-4800) everything works again.

"Hello the QVL list on this specific board (Pro X670-P) does list support for this set of memory (G.Skill Trident Z5 NEO RGB Series F5-6000J3636F16GX2-TZ5NR ) with your previous CPU (AMD AM5 7600x) as being compatible out of the box but it is possible that a BIOS release some time down the road will include support for your current CPU the 7900X3D and your current memory modules to be fully supported with each other under the XMP profiling as it is technically considered a (OC) however we have only released one BIOS for this board at this current time as the one we have released is only a BETA."

Gskill Flare X 5 2x16GB EXPO 6000 CAS36 (Samsung) kit I have has issues on both a Gigabyte B650M Aorus Elite AX with both a 7950x and a 7600 .. and on an ASRock B650E Steel Legend with the 7950x. Booting with EXPO enabled is hit and miss. Once I can finally get it to boot into Windows with EXPO enabled, it's as stable as a rock though

It took many tries initially with fiddling with voltages .. switching the power supply off and THEN try booting up .. I figured out that I would need to make any changes I wanted , except enabling EXPO .. save & exit .. and reboot into BIOS and then enable EXPO and that was my best bet to actually get into Windows.

The only issue I have had is after a bios update. After the update has completed it will occasionally hang during POST with a C5 or CS code being displayed. I found out that by removing the 2nd DIM and reboot then the system will then boot up fine. I then re-install the 2nd DIM and power back on and it boots fine. It's a pain when it happens though.

Anyway, glad to hear it's working now, not so good it was a bad CPU though.

Same... Just got a replacement 7600x and still gives errors in prime95... The shop tested my mobo and ram with another cpu with which they didn't get any errors. I don't know if it was 7600x too or another 7xxx series cpu, so I don't know if it's that all the 7600x's are broken or what, but what I do know is that this will be my last AMD setup in a long while.

My system is now fixed, since I changed out my DDR memory from Samsung to Hynix chips. The G.Skill Trident Z5 NEO RGB memory uses Samsung and swapping to Flare X5 (with Hynix chips) absolutely solved my issue.

It does circle the drain in that X3D chips, and AMD 7 series CPUs, are very touchy in terms of memory and speeds. They're very twitchy and it seems variances in manufacturing tolerances are large enough that the probability of getting components that exceed these tolerances, when you add all the tolerances together, the summation is not that unlikely. Not too common, but, not highly unlikely either.

Asus support does not know under what bios version it was tested. Asus support has no information what BIOS setup was used (voltages, frequencies...) during testing. My conclusion from discussion with ASUS support was that "maybe someone in taiwan managed to finish POST on 4800". Which is true, but for me unbelievable that someone can put it on compatibility list based on this information only.

Based on tips from various forums I managed to finish post with 1.0.0.7c (with significantly increased voltages and memory temperatures around 60-70 degrees), but memtest is failing latest after 15min. Windows managed to boot but crash frequently, linux (debian) does not managed to boot. The only way to wakeup computer from sleep is reset of CMOS.

For me the argument that anything above 4800 is overclocking is not valid, it is the same as if AMD would state that 100MHz is base clock for Ryzen 7950x and anything above is overclocking. AMD says 4.5 to 5.85 and it works exactly as said/written. ASUS writes down 7200, but works only 4800.

I'm very dissapointed with my purchase and with my knowledge it is not possible to identify if AM5 + x670 is experimental, or ASUS design/bios is experimental, or Gskill memories are experimental. Returning complete purchase. Sorry AMD.

Warning for others: If you are not sufficiently knowledgeable and skilled stay with 4800 memories, that are unfortunately not available in my country and have extremely bad timings on levels of ancient ddr3.

You paired one of the lowest end boards that ASUS has to offer with the highest end that AMD AM5 CPU's has in its lineup.

This is an unbalanced build.

Even my older RoG Strix B450 E gaming had better power delivery than the board you have not mentioning the rest of the components.

I was looking at ROG STRIX X670E-F GAMING WIFI (this is on the edge with PCIe ports as the cards are mechanically x16 versions so there might be problem with physical dimensions) and none of compatible memories was available (if we exclude the slowest 4800/48 memories) and the listed Gskill 7200 is not compatible with the board (according to ASUS).

I'm not really builder, I build cca 1xPC per year (starting in ancient times of 386) and this is first time in my life that I had freeze during POST. I do not want any overclocking (e.g. running 7200 memory on 8000), I want to run only frequencies as written on memory sticks (7200/34 in this case). In my previous Intel (sorry for competition brand usage) build I selected in bios my memory and it runs on 1st attempt, post in cca 5seconds and no problems, all tests have run without errors. This time I decided to switch to AMD because I have observed problems with big/small cores scheduler causing problems/slowdowns. Was thinking that same cores=less problems, unfortunately I was wrong.

The board you are looking for is neither the one you have nor the one I recommended.

You are looking at workstation and/or server level requirements and for that, a consumer grade board+cpu won't do you any good. You need extra lanes that only a a Threadripper HEDT can provide.

...Or change the way you network with the computer.

I also have to ask, what is the point to have a 7900XTX at 16X if the board you have doesn't even have support for PCI-e 5.0? You are using a 16X PCI4.0 that is the same bandwidth as the 8X PCI5.0 for the 7900XTX while running it on the ProArt.

Another thing, you are requesting more PCI-E lanes than the CPU can provide, so you will get bottlenecked eventually. From the 3x M.2 slot, the X670P gets, only the first two comes from the CPU, so either one get disabled or share, haven't looked into the manual to be honest.

Ryzen 7950 will offer you 24lanes, 16 for GPU and 8 for two NVME plus 4 to the chipset.
