Can you lower your BCLK?

No, it still locks up. But I am using a "close enough" PLL chip, since the exact one that is on the board is not listed....

 

[Retrorockit]

The x6xx series of workstations are kind of strange. The single CPU machines seem to use the 2 CPU chipset, and 2 QPI CPUs with RDIMMS. This makes them one more step removed from unlocked gaming hardware than other Dell workstations. It also means no unlocked CPUs even for the single socket versions. Intel XTU might get you Turbo speed on all cores. I would try some other FSB tools and see if you get lucky.
I'm seeing some pretty potent builds for that here.

Noob questions, but they're not answered in the various .pdfs that Dell has available: Can the T3500 motherboard 09KPNV support non-ECC as well as ECC RAM? Are there any specific voltages required for suitable RAM. I've contacted some vendors and am relaying their replies to me.

I've already established that the DDR3 RAMs can be 1333MHz and need to be unregistered/unbuffered. The service manual states that dual rank RAM is needed for a 24GB complement. This is for the 09KPNV mobo with an X5680 or W3680 CPU.

Thanks,

Yes it can. Far as I know that goes for all X58 based boards.
The T3500 service manual does state on the Specifications page:

"Memory type: DDR3 1066 MHz & 1333 MHz (Both ECC and Non-ECC)".

[edit]
As for voltages. Have only run 1.5v modules so far. Both XPDFK and 9KPNV boards. Hope that helps.

Okay, that was on page 5, I was looking on page 74, the Memory and Supported Memory Configurations section.

It does, thank you!

I run a mix of standard DDR3 2GB modules, (5x2GB), and CPU-Z still reports 1333MHz with my W3570+09KPNV.

hey so i am running a t3500 on a w3680 at 4.1 and a gtx 1060 and im using the stock psu

but i want to upgrade my gtx 1060 to a rtx 2060

any 1 got an idea what psu is the best for this setup.

sorry for my bad english.

The rtx 2060 is only 12 watts more power draw than the gtx 970 I have in my T3500 (with the original 525W PSU); you may not need a bigger PSU. Have you added more hard drives or other internal devices?

well im getting a 1080ti

would this psu: crosair cx750m psu work with the t3500?

 

[Retrorockit]

That PSU is designed to run a 150W GPU. 75W MB + 75W PCIe cable. Even if the 2060 takes an 8 pin connector if it's under 150W it should be OK with an adaptor.
You need to look up the TDP of a GPU not the "recommended" PSU power.
If you want something like a 1080ti than an aftermarket ATX PSU will work. Then the recommended aftermarket PSU rating will be appropriate.
There are bigger Dell PSUs that can be made to work, but you will need the exact matching wiring harness, and the MB needs to be removed to swap it out. You'll need to do that to remove the old one.
Be sure the new PSU has an adequate 5V. rating to match the old one. Newer computers don't use it much and some newer PSUs can fall short there.

oh oke oke thank you
does the motherboard need a specific aftermarket psu?

 

[Retrorockit]

No but quality matters. Look for ones that have been actually load tested, not just user reviews. There are tier lists. Johnnyguru ,OCN, and Tomshardware have them. Often they can be found on sale for little more than what the inferior ones sell for. The Dell PSUs are "above average" in reliability and protection. An overclocked T3500 with a big GPU will need something equl to the task.

Search Ebay for "Dell T5500 J556T 0J556T Power Supply 875W." That's the PSU for the Dell T5500, a much bigger brother to the T3500. It's basically a drop-in replacement for the stock T3500 PSU, but with 875 Watts of Silver Rated 80+ efficiency power. Be sure to get one WITH the wiring harness as it is a little different than the T3500's harness. This is the unit I bought for my T3500. Once installed it looks like the original PSU and wiring, but with two six-pin cables for the GPU, and an eight-pin connector for the extra CPU in the T5500. DO NOT use that eight-pin connector for a graphics card unless you know how to rewire it.

If you really want an aftermarket power supply, please go to page 22 of this message forum, message #540, and watch the third video to see how someone else approached the PSU replacement using an EVGA 700B PSU.

Hope this helps...

The 1080Ti is a 250 Watt video card, a 750 watt PSU might be just over the minimum for hard gaming with an overclocked CPU and additional fans to keep the temperatures at reasonable levels inside the case.

tnx 4 the info

Soo what do u recomend a 850 aftermarket psu or get a dell t5500 psu and get a adapter/connctor from 6 pin to 8x2 pcie power cabel?

 

[king of swag187]

Curious, but could you do the inverse? IE run the T5500's PSU with a normal system? I think I remember reading somewhere people had issues getting the PSU to start or something crazy

As I wrote earlier, I bought a Dell T5500 (Dell T5500 J556T 0J556T Power Supply 875W ) for one of my T3500s. I think that's a recommendation. Six-to-eight pin video adapters are 99 cents each from China; just over $3 each from US vendors (and they look just like the ones from China.) As I type this there are several tested Dell T5500 J556T 0J556T 875W PSUs (with wiring harnesses) on Ebay for around $40 with free US delivery. Some of the vendors have dozens of them and have very high seller ratings. If you go this route buy two six-to-eight pin PCI-E adapters and use one on each of the Dell 875 Watt PCI-E video cables, rather than a six-pin-socket to 2 eight-pin-plugs adapter. This is just in case the PCI-E video power cables are on different power busses. My GTX 970 has two six-pin PCI-E sockets on its "spine," so there's no need for adapters.

My point here is that the T5500 PSU and its wiring harness are designed for the same wiring layout as in the T3500. All the T5500 wires go right into the places where the T3500's wires went, including those two long SATA power connections for the HDs/SSDs attached to the drive "flap." Wiring is tidy and organized, original airflow/cooling is preserved, and it just looks right. A good aftermarket PSU will also be high quality, but you may end up with the excess length of the SATA wires for the DVD drive(s) being wadded up and shoved under the drive, and extensions plugged onto the other SATA power wires so that they reach the HDs/SSDs clear across the case. And you'll likely pay more.

All the above is my opinion based on my experience with my personal T3500 workstation(s). No promise or guarantee is made or implied; YMMV; experience is the best teacher - bad experiences are the lessons we remember best. If you're a complete beginner ask a more experienced friend to watch over your shoulder so that he/she can say "Oh, I wouldn't do THAT!" right before he ducks down behind your back.

Given that last statement I'll stay with "I don't know."

Well tnx m8t yea that gave me the info that i needit
and yea im a beginner at this stuff so yea still learing from this site but u guys give good info 100%

PSU replacement ... I can understand using another Dell unit for ease of installation. Other than that I could not with good conscience recommend a used one of unknown origin. What kind of use has it seen? Heavy load for years straight possibly. They may say the PSU is tested. Very likely that just means they hit the power switch and it worked. Doubtful the rails were tested for variance under load. 99% chance they did not hook it up to an oscilloscope. Why is any of this important? A 12 volt rail (or any other) that is fluctuating can put a lot of stress on your components.

An aftermarket PSU will give piece of mind, better connection options, and more importantly, some kind of warranty. All the connectors are same as the Dell units. Main thing to deal with is different length cables. Being a beginner you could read some online guides or watch YouTube videos to give an idea what is involved.

Yea i did and i looked up on the aftermarket psu that im getting if the cpu cabel is long enough.

Im getting the croisair tx750M V2 i saw on tomshardware that it is a really good psu so yea it a bit on the expensive side but i know that its good.

Seems like a decent unit. Large single 12 volt rail design which is good. Not sure how long the 8-pin CPU is. If you want to run it behind the main board like original it needs to be at least 25 inches (650mm) long. Otherwise you will need an extender.

By the way ... I am just finishing up installing one of these EVGA units in my #2 box (in signature).

This is what I would recommend because the existing wiring harness is a perfect match for that case and will work perfectly with the 825w Dell PSU, but..

Im getting the croisair tx750M V2

..this is also a good option. The only concern is the CPU 8pin EPS power connector cable length as it has to reach all the way down to the bottom corner of the motherboard at the bottom of the case. If it'll reach that far you'll be ok. Make sure though.

 

[sepheronx]

@lexluthermiester

You have a RTX2080 correct? Which system do you have it in? Cause I am reading that 2060 doesn't work in Legacy. So that would mean that pretty much the RTX series are no good for the T3500?

The cabel is 600mm but imma run it on top but imma take a look at that psu that u are using
May i ask what u are running in ur t3500?

600mm may or may not be just long enough to reach. The board will need to be taken out to remove the old harness anyway. Just a thought.
Still running the 525w Dell unit in that box. Tested it with a multimeter about a year ago and the 12 volt rail was fluctuating about 2-3% during heavy gaming with the power hungry RX 480. Not awful (5% is max) but not optimum either.

[edit]

This is what I would recommend because the existing wiring harness is a perfect match for that case and will work perfectly with the 825w Dell PSU, but..

So the 525w harness works with the 825w unit? That sure makes things easier for those who want to convert. Though they would still be limited to a single 6-pin for GPU power.
