Dell Precision 7540 and 7740 Owner's Thread

I'm looking to get these same kits as you...

not the HX432S20IBK2 as those can't be found anymore i think because they rebranded them to Fury.

There are 2 SKU's though....

1. KF432S20IB1K2 ... which is a dual rank (like the Impact was) ... meaning 16x 1GB chips on a stick (2 rows of 4 on the front and back)
2. KF432S20IBK2 ... which is a single rank (8x 2GB chips on the stick, 1 row of 4 chips on front and back)

From my past experience the majority of problems on Precisions using DDR4 (7510/7710 and newer) is from using Dual Rank memory.

... have you tried them yet?

 

Not yet, I'm looking for a good Black Friday deal.
I wasn't aware about the two different SKU's, thanks for mentioning it

I've checked the Kingston website, and it looks like there are just "sixteen 2G x 8-bit" versions available for 32GB modules.

They just offer 32GB single modules and the 2*32GB module kits

Ah ok, i was checking for the 16GB modules, there are 2 variants there, the 32GB only exists in 16x 2G chips variant....

I don't need to go to 128GB... i would just like to get the 3200MHz
Planning to buy 2 sets of 2x16GB @ 3200MHz if i can get a good deal anywhere tomorrow...

 

I response my own question the promel is this: "Turboboost" not working, one time disabled, the boot is normal, and all works correctly.

 

Could not get the RAM, the online shop where i placed the order just sent me a message that the KF432S20IBK2/32 kits are no longer available, only the KF432S20IB1K2/32 are

 

It took 2 months to receive my ordered RAM, but finally it arrived and I was able to install it. Everything runs smooth, but it's just running on 2667mhz.
First I installed just two modules under the keyboard (total of 64GB) and afterwards all 4 modules (128GB). With both setups it was always running on 2667mhz instead of 3200mhz.
Any idea what I could do?

 

Good evening,
I own a Precision 7540 with Xeon E-2286M, now looking at upgrading the GPU. I bought a Nvidia RTX 3000 on e-bay. I am trying to find the right Thermal Pad, from what I have found, I need part number RX1Y7. I cannot find one anywhere.
Is there anyone found another part number working ?

Thank You,

 

since you can't manually change it in precision models, i guess this is the max it will run at, from the spec sheet it does look like only 16GB modules or smaller can run at 3200MHz. So i guess there is a software or possibly even hardware limitation there.
