Asus Strix X670E-E long boot time after OC memory

[DigitalVHS]

Hello, i have X670E-E and when i OC memory to 5800mhz (default is 5200Mhz) my computer  boot time is so long, about 2-3 min...any idea?  Tnx

The number of profiles available will depend on the memory kit. Are you able to confirm whether your memory kit is present on the QVL for the X670E-E as customer service have instructed above?

My English is not the best, but yes i can confirm my memory stick is on DIM 2 memory slot, if i understand you question

[Silent_Scone]

Is your memory kit listed here.

1.1

1,2

Just timing is 40,40,40,80

And Module Part Number is: KF556C40-32

Maybe my RAM can't handle more then 5200Mhz?

[Silent_Scone · Accepted solution]

The PN you've listed is a single 4800MT micron-based DIMM and hasn't been binned by the memory vendor to operate above 4800MT. 

Manual tuning requires a reasonable understanding of what the associated voltages and timings do, which is why the QVL and EXPO/XMP standards exist. If you want to run a higher frequency, I would advise you to purchase a memory kit present on the QVL list linked in my previous post.

@Silent_Scone Can I manual tuning my memory, I will look on YouTube and maybe any topic on this forum about that>Thanks

Hi @DigitalVHS thank you for sharing the HWiNFO screenshot. From that screenshot I got your memory model as KF556C40-32 for which I was able to get https://www.kingston.com/datasheets/KF556C40BB-32.pdf as the technical specification sheet.

This is not the model you confirmed to Silent_Scone above.

Using the QVL link Slient_Scone posted above your model is NOT on QVL list. See below

Using the memory PDF link I have provided here it seems your memory can go up to 5600 MT/s if it is used with a proper compatible board and CPU. You said

When i go EXPO 1 or 2 i have 3 options  5200mhz ,5600, and 5800 Mhz,,,,only 5200 mhz works fin and but fast, 5600 boot very slow, and on 5800 i dont boot to windows at all.....i watch on youtube some clips and most  people have option 6200 Mhz 6400 Mhz

and your Kingston document is stating

This is why in BIOS you are able to 5200, 5600 in addition to running properly at 4800 which is the default. I believe 5800 is shown as an option due to ASUS Overclocking Algorithms.

If I understand your situation 5800 should only be shown under EXPO I which is an ASUS special configuration.

Under EXPO II you should only see 4800, 5200 and 5600.

You will not be able to go beyond 5600 as that is what your memory manufacturer has configured as the maximum speed for this memory.

Since your memory module is not on QVL and everything works great at 5200, I would just use 5200 and not worry about trying 5600 or 5800. Not every module will run at the advertised maximum speed as there are lots of factors involved in getting to the maximum speed. It seems your board + CPU with this memory module is not going to help you go beyond 5200. 

If you still want faster speed, buy a faster memory. Please keep in mind that you should not mix memory i.e. don't buy another memory stick and try to use it with this current stick. You will have to sell this stick and buy a complete new kit which runs faster.

I hope this helps you.
