Question I need help with BIOS settings ?

After reading several posts on how to configure the BIOS I am still confused and I hope that someone can clarify a couple of things for me.

Configuration:
ASUS TUF GAMING B650-PLUS BIOS version 1636
ASUS TUF RTX 4070 Ti GAMING
M.2_1: Corsair T700 1TB (OS: W11); M.2_2 Kingston 2TB (Data)

In the BIOS, all settings for Advanced->Onboard Devices Config->PCIE Link speed are currently all on AUTO. I am experiencing longer load times with large programs/games so I am wondering if the above settings are correct.
1. I am assuming that the M.2_1 Link Mode should be set to Gen5. Is this correct?
2. Should I set PCIEX16_1 Link mode to Gen4?
3. Does having a M.2 drive in the #1 slot have a negative (performance) effect on the video card?
4. Should I set M.2_2 Link mode to Gen4?

Thanks in advance,
cabwav

PCIe link speed SHOULD be set to Auto. If you know the drive is a PCIe 5.0 drive you CAN set it to that, but it isn't necessary. The motherboard will auto navigate the PCIe link speed and there is really no negative to this. And no, it should not have ANY effect on boot times.

What WILL have an effect on boot times is the number of installed programs and how many of those programs have automatically loading startup processes. There are a lot of programs that automatically configure some of their processes to load with Windows that really don't need to, and that will affect boot times. But what is MORE likely to affect boot times in the BIOS is the type of startup you have configured.

How long is it actually taking to boot to the desktop from the time you press the power button to the time you reach the desktop?

This is a new build so it's basically only the OS (W11 pro) and some tools installed plus one game. The game load time is substantially longer than on my 'old' PC.
The boot time is fine afaik (21 secs from power on to desktop including the password entry). The reason why I was thinking that maybe there was something wrong with the BIOS settings, were the results of the <winsat disk -drive X> test:
- disk random 16.0 read (mbps): 1604 (C); 2970 (D)
- disk sequential 64.0 read (mbps): 6116 (C); 7018 (D)
- disk sequential 64.0 write (mbps): 5921 (C); 3321 (D)
- max latency (ms): 3.487 (C) 0.034 (D)
This looks to me that the C: drive (Crucial T700 1Tb PCIe Gen5) is slower than the D: drive (Kingston FURY Renegade 2 TB PCIe 4.0 x4). What is causing this (or am I reading these results wrong)?

Well, for one thing, larger SSDs just about always have faster performance.

For example, the T700 1TB has sequential maximum 11,700MB/s read and 9500MB/s write. The 2TB model has 12,400MB/s read and 11,800MB/s write.

The Kingston FURY renegade 1TB has 7,300MB/s read and 6,000MB/s write. The 2TB model has 7,300MB/s read and 7,000MB/s write.

Based on those numbers though, the T700 should definitely be much faster than the Kingston drive, but, those are for sequential operations and that kind of performance is only going to happen if you are reading very large sequential files. Most reads and writes are random reads and writes, which happen at much slower speeds, plus your C: drive has MANY other things happening while you are running that test because there are MANY other Windows processes that require access to reading and writing data on that drive in addition to whatever is going on with any test you might be running on it. There are many reasons why a drive might have lower performance though, and it's sometimes hard to say why.

Let me ask this. Are ALL drives connected to this motherboard new? None of them have EVER been used with another system or prior Windows installation, at all?

Where exactly are each drive installed? Is the T700 installed in the M.2_1 slot closest to the CPU so that it is using the CPU lanes and not chipset lanes? Are there any SATA drives attached to the system?

Can you retest both drives using AS SSD or Crystaldiskmark?

Have you looked at the SMART data for those drives to ensure there are no issues with drive health AND that the drives are actually reporting as the model and size of drive that they are supposed to be, because we have seen a LOT of cases where drives have been returned to Amazon or Newegg, and other retailers, with a label swapped off the actual drive and put on some other cheaper drive, and then just sold right back out to the next guy. These retailers don't ever check that kind of thing.

Have you gone to the product support page for your motherboard and downloaded the latest chipset, network adapter(s) and audio controller drivers and installed them. And by that, I do not mean relying on Windows update's native driver support, which usually should only be used as a last resort when no other drives are available for the OS in question, because they generally don't offer the same full feature set that manufacturer drivers do. Sometimes they do, often they do not.

Also, you are several versions behind on BIOS updates. I would highly recommend updating the BIOS to version 2214, then do a hard reset of the BIOS to ensure everything actually resets and no previous hardware settings "stick". You will need to reconfigure any custom BIOS settings you had set after doing the hard reset.


BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, IF the problem is related to a lack of video signal, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.

Trying a different monitor as well, if possible, is also a good idea if there is a lack of display. It happens.

Thank you for your detailed reply, it definitely helps me in understanding where to look for a solution. In reply to your questions:
1. All drives are new and have never been used before. W11 install was done on the C: drive for the first time.
2. The T700 C: drive is installed in the M.2_1 slot nearest to the CPU, the Kingston D: drive is installed in the M.2_3 slot (the board has three M.2 slots in total, this slot is the one nearest to the front of the board, when you look at the board with the back connector panel top left). There are no other drives attached, just these two M.2 drives.
3. I tested both drives with Crystal DiskMark, the results are below. These results seem to indicate that the C: drive is indeed faster than the D: drive, but this does not explain why I percieve the loading times of large programs to be slower/sluggish compared to my previous build(s).
4. The SMART data (Crucial Storage Executive) reports for drive C: good health, no criticals, device temp 58C, no media error counts and for the Kingston drive D: 'good health' (no further details). I already did a firmware update, current version is PACR5103. Both drives are reported with their advertised capacities: 1TB for C: and 2TB for D:. All components are bought at a renowed Dutch computer parts retailer and I would be very surprised if they were involved in shady practices 😀
5. I did download the latest chipset driver, but not the network adapter driver or audio controller driver (because I thought it didn't matter). I will install these drivers next thing.
6. And finally, the BIOS update. The latest update for my mobo is 1811 (not 2214). I did a lot of reading in various forums and found that people generally recommended to not install the 1811 update because of stability issues. Version 1654 was advised as being a stable and reliable version. This 1654 version is only one up from the version of my mobo, and I have been reluctant to install another BIOS version because (a) I didn't want to mess with a working system and (b) the possible risk of making things worse because of the problems ASUS has had with previous BIOS updates.

I would appreciate your advice and/or a confirmation to go ahead and install the 1811 version of the BIOS before doing anything drastic.

Crystal DiskMark results (sequential read/write):
C:
11703 / 9179 mbps
11071 / 3846 mbps
5719 / 3842 mbps
87 / 275 mbps

D:
6996 / 6852 mbps
7091 / 6717 mbps
4220 / 4685 mbps
77 / 275 mbps
 
6. And finally, the BIOS update. The latest update for my mobo is 1811 (not 2214).
Nope. And, these days, if you are not willing to update the BIOS then you better be willing to have a system with problems, because BIOS updates are MORE common than chipset driver updates and that is simply a fact. And, manufacturers do NOT release BIOS updates unless there is a damn good reason for it, because it costs MONEY to develop new firmware, so they don't do it just for kicks. I'd say about fully 50% of the problems I encounter on this forum are resolved by a BIOS update. But hey, that's up to you man.

Be sure to remember to do a hard reset of the BIOS after you update it. In some cases previous hardware table configurations occasionally "stick" and doing a hard reset insures that the settings are forced to be reset based on currently installed hardware.
