Question Does these XMP RAM module speeds look normal ?

[tzr916]

This machine has been stable for years... On the main BIOS page it shows the ram status. Curious why do dimms A1 + B1 show 2133MHz, but dims A2 + B2 show 100MHz ? Maybe that's normal when set to XMP1 mode?

In MemTest86:
Dimm1 = g skill f4 3200c16 8gvgb
Dimm2 = g skill f4 3200c16 8gvkb
Dimm3 = g skill f4 3200c16 8gvgb
Dimm4 = g skill f4 3200c16 8gvkb

Normal? No.

Make sure all of your memory to firmly seated and that slots are free from debris.

If you disable XMP, what happens?

Have you reset your BIOS since you noticed this?

Those troubled pair probably just need a reseat, pull out - put back.

Check CPUz under memory tab, frequency should say 1600 (CPUz reports single data rate * it by 2 for DDR)

Seems like I have TWO bad stick....

Tried:
- disable xmp, save, restart > same issue
- re-seat all dimms, restart > same issue.
- clear cmos, load defaults, save, restart > same issue.
- remove dimms A1 and B1, restart > NO POST.
- put either of the dimms that were in A2/B2 into A2 > NO POST.
- put either of the dimms in that were in A1/B1 into A2 > POST good and RAM status good.
- put both of the dimms in that were in A1/B1 into A2/B2 > POST good and RAM status good.

With all dimms plugged in:
- Windows runs fine and says there's 32GB
- MemTest86 shows 4 dimms and 32GB
- full PASS from MemTest86 default test (2 pass)
- but ASUS windows AI Suite software showed some really odd stuff for dimms A2/B2:

dimms A1/B1 look normal:

Where are those four ram sticks coming from? Did you buy them all in one single kit of four or did you mix two kits of two sticks? Even though the ram model is exactly the same, mixing kits might not work properly.

Shouldn't each stick work by itself in slot A2 ?
I'm getting NO POST when I put ONE stick in A2... Then again with the other stick.

I got the motherboard/CPU/RAM from eBay three years ago. It's run fine since.... Well, until I upgraded from Win 10 to Win 11, then I started getting hard freeze about twice a week 9p~11pm. I passed Prime95 and Furmark and Hard Disk Sentinal tests... So I ran MemTest86 and it came back full PASS. That's when I saw the BIOS page with those odd status numbers.

NOTE: The part numbers printed on the sticks are slightly different:
2x good = f4-3200c16d-8gvkb
2x bad? = f4-3200c16d-8gvgb (NO POST when tried individually in slot A2)

Yes, they should work with single stick also.
Check cpu socket for bent/broken pins.
Make several high resolution photos of cpu socket from different angles and show here.

Let me clarify:
f4-3200c16d-8gvkb = GOOD POST when tried individually in slot A2.
f4-3200c16d-8gvgb = NO POST when tried individually in slot A2.

Disable xmp (set dram frequency to 2133mhz),
set DDR voltage to 1.35V and
try again with NO POST modules.

 

[tzr916]

Hmm, I did test both NO POST modules with XMP disabled.

I've already put everything back together (minus the bad modules)... But if you really think it's necessary, I may have time tomorrow to try your suggestion to manually set frequency and voltage.

Also clean gold contacts on modules with eraser.
Blow out dust from ram slots.
It might be just a bad contact.
