@heady pulsar

#

tried reseating, unlocking via windos + r msconfig

#

etc

This may sound funny, but does this happen with XMP off?

havent tested didnt think it would be the issue

heady pulsar Sep 5, 2023, 8:41 AM

#

I'm going to guess this probably works fine in another computer too

friend doesnt have one to test the ram out

#

unfortunately

heady pulsar Sep 5, 2023, 8:41 AM

#

Test single sticks

#

Also some unoptimal configs

#

E.g. both sticks on same channel

#

Inb4 dead mem channel

#

heady pulsar E.g. both sticks on same channel

thats not the issue, ram is on 2/4

heady pulsar Sep 5, 2023, 8:42 AM

#

keen coral thats not the issue, ram is on 2/4

What? I mean, put it on 1/2 or 3/4

#

Basically intentionally breaking dual channel

keen coral Sep 5, 2023, 8:43 AM

#

shit

#

ok

heady pulsar Sep 5, 2023, 8:43 AM

#

If 1/2 shows the entire 16GB, then try 3/4

#

If it's still the same, then now try any of the following:

1/3
2/3
1/4

#

nonstandard placements that would still result in dual channel

keen coral Sep 5, 2023, 8:45 AM

#

gimme a sec

#

poor mf changed his mobo from a dead one and he may have got another bad one

heady pulsar Sep 5, 2023, 8:46 AM

#

Yeah, I usually don't expect ram to just go "hasta la vista" so quickly

keen coral Sep 5, 2023, 8:47 AM

#

tbf the ram is old

#

like 4 years old

#

maybe more

#

12.2gb available

#

now

#

with 1/2

heady pulsar Sep 5, 2023, 8:50 AM

#

3/4?

#

Seems weird it's reserving a quarter of the RAM stick

#

Starting to look really sussy

keen coral Sep 5, 2023, 8:51 AM

#

hes trying the rest now

#

wgat could be the issue here?

heady pulsar Sep 5, 2023, 8:52 AM

#

By any chance, does the computer use AMD integrated graphics?

keen coral Sep 5, 2023, 8:52 AM

#

i assumed dead stick/mobo ram channel

keen coral Sep 5, 2023, 8:53 AM

#

heady pulsar By any chance, does the computer use AMD integrated graphics?

no hes got a ryzen 5 2600x in a b550 mobo

heady pulsar Sep 5, 2023, 8:53 AM

#

Then we can rule out reserved-for-VRAM memory

keen coral Sep 5, 2023, 8:53 AM

#

yup

heady pulsar Sep 5, 2023, 8:53 AM

#

Definitely very odd

keen coral Sep 5, 2023, 8:53 AM

#

1/4 still 12.2

heady pulsar Sep 5, 2023, 8:54 AM

#

Hmm

#

With the stick at 1 in, remove the other stick. What's the RAM seen, 4.2GB or 8GB?

keen coral Sep 5, 2023, 8:54 AM

#

we're testing out the other configs first

heady pulsar Sep 5, 2023, 8:54 AM

#

(I will be driving very soon and may be unrespnsive)

keen coral Sep 5, 2023, 8:55 AM

#

and then doing one by one

heady pulsar (I will be driving very soon and may be unrespnsive)

dw about it

heady pulsar Sep 5, 2023, 8:55 AM

#

IIRC the last untested config is 2/3

keen coral Sep 5, 2023, 8:55 AM

#

thats what hes doing

#

and 3/4

#

2/3 is 12.6

heady pulsar Sep 5, 2023, 8:59 AM

#

2/4 to double check

keen coral Sep 5, 2023, 8:59 AM

#

3/4 made the pc go on a boot loop

#

with the peripherals not opening

heady pulsar Sep 5, 2023, 9:00 AM

#

f

#

What was the issue with the last board?

keen coral Sep 5, 2023, 9:01 AM

#

vrms got burnt

#

lul

#

asrock

#

so its the mobo

#

great
