Ram Won't Work
My Dell 7820 only runs 4 sticks of 3200 ram 32g clocked as 2933. If I put ram 5 and/or 6 in it, it won't bios. I get "Bios repairing flash", then a constant "no ram flash." Bios v. 2.39
It's supposed to run 6 sticks of 3200 clocked at 2933 by the CPU.
No matter which of the 6 sticks of ram I use by swapping them out and around, it'll run only 4 sticks, max.
I haven't pulled the jumper to reset bios, but I have used the bios reset inside of the bios utility to set it back to factory settings and also to set it to the latest bios setting, all to no avail.
I'm stumped I do not have the same brand of ram in all slots, but they all will work independently in any order as long as I only use 4 sticks.
Any ideals would be appreciated.
Thanks,
David

Replace the size 2032 battery if it hasn't been done in the last 5 years. Bad batteries cause BIOS issues, and BIOS could be the reason for not recognizing 6 sticks of RAM.
If still no luck, reseat the CPU; during which check for any bent socket pins.

It would help if you posted the exact model number otherwise that is impossible to answer.

Assuming you are working with a single CPU configurations. The following table illustrates the memory configuration and population rules for the Dell Precision Tower 7820, go to the link for a larger view:
Clear CMOS via jumper to see if it may help.

@JOcean It is a 7820 as my name implies. Single X6230 with 6 slots. 3200 speed ram. Every piece of ram will run in the 7820 in any order as long as I only use 4 sticks.

@My 7820 Sorry my bad, as I was not sure if that was a reference to your system.

@bradthetechnut
Well sir, I do believe that you figured it out. I removed the CPU and best I could tell there are some bent over pins.
Not being one to give up I attempted to straighten them. Now it only reads 3 sticks of ram. lmao
I guess I'll get another motherboard or else just accept it only runs 96gigs now and stop fooling with it. I wanted to use it for video processing, but instead may get another unit and just use this one to surf the web? I have a Xeon Silver 4114 and a couple sticks of 8gig ram I can put in it for that purpose which should work just fine.
Thanks for your expertise.

@My 7820
One can always take a photo of the socket and expand it to see the pins, but it looks like you got it.
Thanks for the accepted solution. I was definitely hoping you were going to have better luck with it.
