Is there a modded BIOS for the T5820 that allows the ReBAR option to be active (driver added)?

 

[Deslok]

Just picked up a T7910 has anyone had any luck getting a TB3 card in it or the T5810? ReBar would be nice too but it looks like I could follow the mods for the T5810 so that's settled if I feel adventurous.

What I would do is flash the original a32 you had. Then upgrade to a34 then follow the process for the tbu using the Payne drivers (ignore the new version) There is a guide in youtube. I have somewhere the link if you cannot find.

That is what i did. But i won't try the unlock again. My Problem is, that need the standby Mode.
With my current 2697V3 the difference between Multicore Point's in Cinebench are quite small (around 10%) so i don't think that is worth the effort for me.

I bought a second 5810 to build an upgrade for the current T3610 my friend got. For the SSDs i got a very good deal for 5x 256GB drives (10€ per drive). Biufication does work on both 16x Slots?
I am searching for V4 CPUs but the are still quite expensive. I think the 2690v4 won't be much faster than the 2697v3 and costs double the price.

Hello there,

Proud owner of T3610 from Warsaw, Poland !

Few days ago I`ve bought 4 sticks of 16GB@1866DDR3 ECC sticks, for as low as $50

They all work like a charm !

Greetings for all from Poland !

 

[stefan0815]

Hey Bart,
there is a polish ebay seller who offeres bare T5810 for 63€ which is a very good price in the moment.
DDR3 ECC is quite cheap now, but DDR4 ECC (especially the first generation up to 2666MHz) is nearly as cheep. I got 4x16GB for around 50€ to (but not on ebay Kleinanzeigen from a private seller, which is like craigslist)

No idea on bifurcation. Regarding processor I would recommend 1660v3. Performs really well for me and easily overclocked to 4.5-4.6 Ghz so pretty good for gaming.

Hi All,

I am wondering if anyone could help me identifying one part on the T7500 mainboard. It is a small chip which I believe is used to control the chipset fan. I was given the board with this component missing and it is causing the fan not to work.

The marking on the board is U53 and it is located close to the RAM slots.

If anyone has this board or T5500 (which also has this component) and could just take a close-up clear photo and/or read the markings of this chip I would be very grateful.

I will then try to source this chip and replace it.

I checked around other fan connectors but those use different chips.

Thank you

Your best bet would be to find a spare board either to replace or to use as parts. Depending on where you live in the world this might be easy.

I have managed to identify this chip (someone has sent me a close-up photo of it) and it is K401 top marking, which looks like TS321 operational amplifier. Easy to get chip.

I am posting this info for anyone needing it in the future.

Excellent! Good you got it figured out!

Can anyone explain the wattage discrepancy?? From technical specs and what HWiNFO reports?
This is a Dell Precision 3420.

Does this mean I CAN use up to a 75W card or is that some sort of number for a 50W card running some full load?

Could be a typo or it could be a suggested power limit for a card which relies on slot power alone. Either way, you should safe to use any card that has a lower power draw.

To be fair, That is a small form factor system, so the 50W suggestion could be a limitation of the PSU included with that system which is 180w, as noted in the official Dell specs page;
https://www.dell.com/support/manual...a0c2a7-f6a4-4ffc-b15f-549f237234a9&lang=en-us
What card were you thinking of using? I have experience with those systems and can help you get a GPU that will work well with it.

My machine actually came with 240W. I don't know if I am really looking looking. I've considered a400 but it has a 64bit width bus or and I don't know if it would be worse for the retro games I been playing and seems a bit overpriced. I had a sparkle arc a310 card in the past but I didnt like the noise from the fan and conflict with igpu driver so I returned it... I want the encoding and decoding capability of the arc card with some tiny amount of ray tracing cores just to have the hardware capability. My current card is 2GB vram and I have no complaints on that but 4GB+ would probably be ideal. If a battlemage low pro card came out I would probably try again but probably with asrock. I've looked at a lot of low pro gpus, and there's always something missing based on what I'm looking for

Far enough. I have the Optiplex version of that chassis and it came with a 240W as well.

I currently have a Quadro K1200 4GB in mine. It does well enough for my needs, which is a bedroom media center with some light gaming for casual use. The single slot PCIe design will be the real limiting factor for it. No complaint about the noise though. The K1200 is fair quiet, even under load. Of course the term "quiet" is subjective and varies wildly from person to person as it highly depends on preferences.

If a battlemage low pro card came out I would probably try again but probably with asrock. I've looked at a lot of low pro gpus, and there's always something missing based on what I'm looking for

I think that might be in the works. Considering that the low profile ARC cards were somewhat of a sleeper hit for them, Intel and AIBs are likely to continue in those efforts.

Not sure if anyone can help. I am currently upgrading a T7500 and need to know which PERC cable the PERC 6/I controller uses with the T7500 workstation. Internet searches suggest it is the OP322X but i almost certain that that cable is too short. The correct cable is routed over the expansion slot area to connect to the drives with the PERC card installed in PCIE slot 1.

If anyone has a T7500 with a PERC 6?i and the cable correctly routed could you let me kow what the part number is for the cable? I think it may be CH328 but i am not sure.

Many thanks

So the right cable but it's definitely falling out of favor, technically it's just a SFF 8484 to 8482 cable for the perk 6i, it is nowhere near as common as the much later SFF 8087 that you'll find on many more modern controllers up until the replacement with sas HD for 12 GB connectivity and interoperability with some versions of PCI Express, for what you're going to pay to get a correct cable on something that old if you don't already have one I would consider looking around on eBay for something like a perk h310 or one of its more recent derivatives you can find those under $30 with a variety of cables and as low as 10 without at that point you can get commodity cables on Amazon for like $10 each.( The h310 is also going to be faster with support for larger drives)

Many thanks for the info. My intention is to max it out on period correct and then potentially do a few upgrades. I recall reading somwhere that the T7500 can be a bit picky on which PERC controller you can use. If it will take it i may look at something like the H730.

On an unconnected note i also have a Precision T7610 into which i will be putting 4 SAS drives. I know that the intergrated controller is a LSI 2308 and iw ill be using the machine primarily for running BOINC. Would there be any advantage to upgrading the controller? i have no idea if the LSI 2308 controller is good, bad or ugly.

Thankfully i am keeping my T3610 simple with sata.

Man where were you when I was selling mine, I had it maxed out with a pair of x5690's the big heatsinks and 192gb ram, as far as it being picky I don't remember it having any issues with any controllers I tried and I did have an H310 in it at minimum, the H730 should be fine as well(can't hurt to try at least)

The LSI 2308 is a perfectly fine controller it's the chip TONS of raid cards were built on https://www.servethehome.com/lsi-sas-2308-raid-controller-hba-information-listing/ and handles large drives at SATA 3 speeds just fine, just like it's sibling the 3008 if you have it save the lanes(honestly the 3008 in my 7910 is great I'm tempted to get an expander for more drives though.

At one point I had a mix of 10 T3500, 5500 and 7500 machines all running Boinc. When energy prices went crazy a few years ago i got rid of them all but i recently picked up one last T7500. I am waiting on some ram to get it up to the 192GB limit, thinking of running a RAM drive for the Boinc installation. Other than that I may add a couple of GTX 1660's into it for Cuda crunching.

Hello,
If someone has a T5810 or a similar workstation, I'm curious why the fan speed is always super slow, even on "auto" in the BIOS.
My machine gets too hot when the RTX 2060 Super is at 100% and all the fans are completely silent.
Obviously, I don't want to put everything at max speed all the time it would be noisy and unnecessary.
Anyone managed to fix this issue ?

This is a known problem. Dell's estimation of too hot is much higher than what many people are comfortable with. As such, one needs a utility to control the system fans.
My personal fav is LibreHardware monitor;
https://github.com/LibreHardwareMonitor/LibreHardwareMonitor
However, FanControl is also very good;
https://getfancontrol.com/
https://github.com/Rem0o/FanControl.Releases/releases

Give them both a try and see what they do for you.

Lol they don't want me to bother my coworkers with the fan noise, with my office machine... at home.
This is counterproductive, because the system fans are silent, but the RTX 2060 Super is not silent, spinning at 2800ish RPM in heavy games.
Dell would reply it was not sold with that card and it's not their problem I guess.
I just tried fan control and could see only my GPU In FanControl which is useless for me, I see they use libre hw monitor so it's kind of the same techno?

I managed to add a fan at the back, a customized official Dell Fan inserted in the "hdd_fan" header.


I have the impression that my 5810 can only control the fans in the BIOS, and that bios is.... disappointing to say the least.

I'm so sorry. I thought those would work. Maybe Speedfan? I know that Speedfan works on my T3500.

SpeedFan - Access temperature sensor in your computer

It's older but should still work for your system. Give it a try.

You may want to find a better fan for that back vent. The one you're using in that photo is a bit noisy when it ramps up. A larger 100mm( or maybe is was a 120mm) fan would be much better for airflow. Front fans might help too if your system doesn't have any.

You're right when you say it's noisy at max speed, it's just that:
- it's an official Dell fan from an old optiplex so I can plug it to the hdd_fan header
- it's the right size to avoid blocking the case from closing
- Because I can't speed it up, it's not too noisy anyways

I think it's impossible to get any info regarding the fans in Windows I see zero fans =/

When it started up, did you allow it to check for Dell specific fan ICs? It should have asked.
