Precision T3500 and PCIe x16 graphics card, Windows 10 x64bit

Other than the slot being bad or the card not going all the way down into the slot i see no reason why it should not work fine in either slot.

AFAIKT only the XPDFK board works with the newer spec.

Chris M might have insight on which processors were validated with which version of the board.

 The black slot is not wired X16 so there may also be a slot power problem where it tries to draw too much power.   PCI-E 1.0 and 2.0 have lower speed and power output than PCI-E 2.1 and 3.0.

If you don't have the original 525W power supply the other issue may be that the power supply DOES NOT HAVE enough power on the 3.3v /5v rails.   Dell has 150 to 225w combined on these rails.

Many off brand units are lacking in this area.

EVGA 750B1 works fine but B2 BQ G2 does not for this exact reason.

Thank you for information.

I have the original 525W power supply, and Nvidia GeForce GTX 1050 Ti can take max 75W and does not have an additional power connector, while GTX 1060 SC Gaming that I am going to try is 120W and has a 6-pin power connector, that is also available on the power supply.

At the link below they have approved Intel X5690 for the Dell 9KPNV motherboard:

I will post back after I inspect the blue slot and try GTX 1060 SC graphics card.

I don't have a list as such, only access to the parts database (sorry, I can't share this)

If a part is listed against a model number in the database it means it shipped with that model of system and is therefore supported.

I believe I have the latest A17 BIOS for Precision T3500.

I know that Windows 10 re-activation may be an issue after the CPU upgrade, so, I am looking into that as well.

There are also 2 slots in the rear for 2 more fans.

There are no headers but tapping SATA power to Molex works.  If you want to control them you could add a fan controller into the 3.5 inch flex bay slot.  This has been done with2 Arctic F8 80mm case fans

Make sure to update the bios BEFORE trying to change the CPU. Otherwise its going to be a headache putting old cpu back.

Its also helpful for future users if this works to post back the S spec of the cpu part, the bios version, and the motherboard part number.

Copper heatsink is recommended.

Part Number(s): U016F/ 0U016FHeatsink Assembly for Primary CPU, Performance

Some also add secondary fan.

Thank you for details.

I do not think I need to add any fans at this time.

The CPU runs at about 50 degC, and graphics card is at about 60 degC.

I will measure under intensive load and re-evaluate after upgrades.

I am back with some updates.

I inspected the blue slot and did not see anything wrong with pins and in general.

Nvidia GeForce GTX 1060 SC Gaming 6GB installed in the blue PCIe x16 slot had Windows freezing in the middle of boot-up with continuous beep, and worked fine in the black PCIe x16 slot, similar to Nvidia GeForce GTX 1050 Ti 4GB that I tried previously.

The only difference is that now the front fans in my Precision T3500 run all the time, although the CPU and GPU temperatures did not change much, so the overall noise level is higher with GTX 1060 than it was with GTX 1050. As both cards made by EVGA are 6.8 inch and have Single Fan, I suppose this is normal, because the GTX 1060 probably gets hotter than GTX 1050.

I need to figure out why the blue PCIe x16 slot does not work as expected. Is there an issue with motherboard or CPU perhaps? Does Dell have diagnostics tools that would help in this case?

Please help.

Any information about Dell 9KPNV motherboard A17 BIOS supporting UEFI?

Update: In EVGA forum they say that GTX 1050 and 1060 support both, Legacy and UEFI systems, so this should not matter.

Disabled SERR messages in BIOS, the issue persisted.

I am going to remove the only other PCIe card, Asus Xonar DGX audio card, and see if it allows running GTX 1060 in the blue slot.

UEFI is not a feature its a windows 8 and up Bios with key inside.  There is NO UEFI bios for the older systems.

Yes, so I wanted to know if my Precision T3500 was old enough to not have UEFI support in BIOS.

I actually tried the steps in the link below and did not see UEFI Firmware Settings, which confirmed that A17 BIOS does not support UEFI.

www.dell.com/.../access-uefi--bios--system-setup-from-windows-on-your-dell-system

But, EVGA forum guys already confirmed that it would not matter because GTX 1050 and 1060 graphics cards support both, Legacy and UEFI BIOS.

Update: I re-flashed the BIOS, reset the settings to defaults, and set them back up, but have not tried the blue slot after that yet.

 I also run built-in BIOS diagnostics, and online motherboard test, both came up clean on everything, including PCIe related tests.

I found a user with
DXP051  XPS 400 with GTX 1080TI ,  Bios A02 ,  32 bit windows 10  Pentium D 830

These systems support Crossfire but they DO NOT support SLI.  The 1050TI also does not support SLI.  I don't think the 1060 supports SLI either only Single card.  For SLI you must use 1070 or 1080.

I have tried installing GTX 1050 Ti into the blue slot, while GTX 1060 SC was still installed in the secondary black PCIe x16 slot, and it worked! Windows did not recognize GTX 1050 Ti and auto-install the drivers, but I successfully installed the drivers manually.

So, for some unknown to me reason, when there is just one graphics card, it should be installed in the "secondary" black PCIe x16 slot, and the second graphics card can be added to "primary" blue slot.

I have not tried with just one graphics card in the blue slot after BIOS re-flash and reset, but I am not going to spend time on that anymore.

I am not trying to use SLI or Crossfire, Speedstep.

My question was and is why the primary PCIe x16 blue slot does not work in my system in a single graphics card configuration, but I do not want to spend more time experimenting, as long as the blue slot works fine when used in two graphics cards configuration (when another graphics card is installed in the black slot).

I can return one of the graphics cards, or leave both running to use for crypto-currency mining.
