X99 Memory issues

Psittac · February 16, 2022

I'm trying to get my old X99 machine running again to give it to a friend as an upgrade to his AM3 system. Problem is it was ALWAYS a pain to get correct in the first place and a couple ram sticks were dieing BEFORE I let another friend borrow it for 9 months at which point he brought it back to me and said something popped and he thought it was the power supply. If I remember correctly he swapped his other PSU in and it was working at the time so I'm pretty sure everything is functional.

So right now I have a frankenstien with the x99 cpu mb ram and hsf sitting next to my friends old computer running off it's psu and I can't get it to post or display.

gpu is an hd5830

ram is 8x4g corsair lpx 2400

cpu 5820x

mb Asus Tuf X99 (X99 sabertooth I believe)

Anyways even when new this thing was fineky AF. But can I get some direction on how to figure out which sticks are dead or what slots require a stick? I'd like to try just one ram stick at a time but that doesn't seem to work. I have other memory kit's and other computers that I could try and test with but I'm in the process of formatting my main machine because it decided to throw a fit after pulling the memory out and trying to test a stick (another post for that problem though)

Grab the manual there.

Spoiler

Dimm D1 is the preferred slot. I'd try clearing CMOS if you haven't already then going through the sticks one at a time in D1. B1 is the next preferred slot, so if none work in D1, I'd try that slot second.

Did you clear CMOS on your main rig before formatting?(hopefully)

What was this computer originally doing that was being finnicky?

Thank you

I tried the manual already and didn't find anything in the sections that made sense to me, so I figured I would ask on here because the information is usually better and far faster.

I'm going to try your recommendation, thank you very much.

I didn't clear cmos on main rig but I did go into uefi which said it had reset, assumed that was the same thing without pushing the button. I haven't formatted it yet.

The old X99 system is the one that was always finnicky, I actually used it for a very short time because of it. It just didn't like posting all the time and the memory was hit or miss. I really can't remember but the lack of being able to overclock it convinced me to build another machine. the X99 was supposed to be my ultimate machine and I wasted A LOT of money on it and it never was right for many reasons. Was my first hardline build and only HEDT. Was out of the hobby for a bit and didn't even know HEDT was a thing, just went into micro center and said "I heard they have more than 4 cores now. Throw in dual R9 380's that weren't standard board layout so the waterblocks in the mail from ekwb were paper weights before I got them and only being able to return one gpu etc etc the list goes on. I just ditched that computer and never really used it.

For that computer, I'd use the button. I saw that that's an AM4 system. When you reset CMOS and turn it back on, give it a minute to retrain memory. Sometimes it takes a few minutes. I know my 5800x system did.

So it's had memory issues in the past? If the different sticks of ram doesn't work, I'd remove the CPU and make sure there's no bad pins. Maybe there's something that got missed when you originally built it. I had a 7700k and a mobo with a bent pin(put it in storage in the box, but no socket cover) I couldn't get that to post in dual channel, but could run 2 sticks in single channel on that.

More so on AMD, but some people have had issues with LPX. I haven't personally. Do you have any non Corsair ram laying around you can try? I know your main build has Corsair as well, maybe that build just doesn't want to cooperate with Corsair.
