BTW they say not until Dec 27th but I guess they have build it lol

Damn! That's more than a month..

 

[frigider]

still me.

this is bugging me:

how tight should the screws be on the heatsinks? (t7810 - but that 's a general question, right?)

do you go until they stop?
should i go back like half a cycle after reaching full stop?

when i do go back half a cycle after full stop and remove the heatsink after a while there's almost no paste in the middle of the CPU - guess the heatsink makes perfect contact?

 

[lexluthermiester]

do you go until they stop?

This. Those screws have self-stops built in as a part of the design. Screw them in until they stop. Then you're done.

i can finally breathe now.

yeah it makes sense for them to be designed this way.

Hey does anyone know the pinout for the Dell precision power distribution board. Should be relatively the same t3600,t5600,5610,5810 ect. I'm specifically looking at the 10 pin CPU plug. My 5810 has 2 so the same board can be used in a 7 series or maybe it's the exact same board from the 5610 dual socket. I really only want to know if any of them are dedicated voltage sense wires.

I have a Dell T3500 and if i want to upgrade to a Xeon 6C X5690 3.46Ghz 12MB 6.40GTs 130W Processor | 3.73Ghz Max Turbo Frequency (SLBVX) I must change heatsink?
My Intel® Xeon® Processor E5645 12M Cache, 2.40 GHz, 5.86 GT/s Intel® QPI. with 24gb ram works pretty well. Can play 4k videos with only 10-20% usage of the CPU. I can see it can work up to 2,87ghz when the manufacturer claims it only goes to 2,67. If i need to change the two 120mm front fans with 5pins how to find replacement fans? The most are on 3 or 4pin. Can i use an adapter and get the sensor to the fans to work to?

Don't have a 3500 but I looked some stuff up and it doesn't appear like it was much different back then. Those 5 pin fans should only have 4 wires. The colors matter so whatever fans you get just un pin the 4 pin connector and take your old 5 pin fans and un pin those as well. Put your new fan wires in dells correct order into those old 5 pin connectors and plug them in. They sell adapters but I never seen a reason to buy them. And supposedly there is an uprated copper heatsink you can buy.

If you want to upgrade to an X5690, yes, you'll need the better heatsink and you'll need to attach a fan to it.
You likely have the following;

Dell Precision Workstation T3500 T5500 T7500 CPU Heatsink T021F 0T021F | eBay

Part number: T021F, 0T021F. Compatible Models: Precision T3500 T5500 T7500. Manufacturer: Dell.

www.ebay.com

This heatsink can handle up to about 100W of thermal load. The X5690 is a 130W part.

You'll need one like the following;

Dell Precision T3500 T5500 T7500 Workstation oem Heatsink U016F. SKU156187 | eBay

Up for Sale is a genuineDELL U016F unit. This DELL U016F is in excellent condition and ready to be redeployed. A representative will respond quickly. The item you will be receiving will be labeled with part number U016F.

www.ebay.com

They're not expensive. This heatsink can handle up to about 170W of thermal load, which is more than enough for the CPU you want to get.
Tip for optimal performance: Get an 80mm fan and attach it directly to the heatsink, don't use the shroud. A model like the following would be excellent;

About the CPU upgrade, have you give thought to the W3680/W3690? I ask because they are unlocked CPU models and can be soft overclocked in a T3500 using ThrottleStop.

Lex....Sometimes I wished I would have bought the 5690 but my 5670 is oc and running @4.3 Ghz. and it's fine until I start watching some 4k YouTube videos. I think you mentioned to me way back when about the W3680/W3690 but I had already purcheased the 5670. The 5690's were close to $75 when I bought my 5670 but I see they have come down a bunch.

 

[lexluthermiester]

it's fine until I start watching some 4k YouTube videos.

I would think that's more GPU related than CPU. What GPU do you have paired with it?

 

[Oldschool297]

I must be lucky because it seems like i have such a heatsink even if the processor is smaller. My look like this. Is W3680/W3690 a better options?

I can play 8k with E5645 and a old Nvidia Quadro Fx 3500 256mb and 24gb 1333mhz ram. I use Windows 8.1 Pro it maybe makes difference. It only uses about 20-30% of the cpu. But the point is that the fps may not be at the highest.

 

[Mr Bill]

AMD Radeon HD 7770 2GB GDDR5... I guess I should have elaborated more, it plays the video's great, but I can feel more heat coming out of the case and the fan speeds way up, when I begin to watch the 4k videos, it's fine with 1080. I don't have any side covers on any of my PC's, but I'm sure I don't have a patent on that.

That might be the difference, I have a backup image of Windows 7 for this PC maybe I should try that and see how it performs, I'm using 11 right now.

There's your issue, you need a newer GPU for 4K video. RX470 or RX480 would fit the bill for you.

For some reason i can't see the motherboard temp on my Dell T3500. I have tried with the program Speccy. I only see Cpu temp and gpu and hard drive. I have the hard drive on 30 and cpu on 21 in idle and on 30-40 playing video. So i guess it can be cool. Can't this dell show motherboard temp?

 

[lexluthermiester]

For some reason i can't see the motherboard temp on my Dell T3500.

They don't have one. Don't worry about it. The X58 chipset in the T3500 has a large heatsink and it never gets too hot.

 

[Oldschool297]

Thanks i have a cooler master 500w rs.500 acab ver 2 psu but the fan has started to make small noices. I plug it out and dropped a few dropped of suited oil as the back plug was easy to plug out. But i do not know how long it last. What types of psu can it handle. It must have EPS12v from what i have read. https://www.dell.com/community/Desk...500-4-pin-cpu-cable-8-pin-socket/td-p/4498152

I thougt about buying https://www.thermaltake.com/smart-rgb-500w-230v.html but don't know if it suits. I guess the cpu power is on 8pin? https://www.amazon.com/XPDFK-Dell-Precision-Motherboard-LGA1366/dp/B018KX2WNG

Well as an adult you pay for any Xmas gift you get. Sooo that's still a damn nice present lol.

 

[smihaila]

Yeah I can try that when I get my hands on it (shipping takes forever). The guy who tried with just the 8 pin used it for mining, not sure if he had flashed some VGA BIOS for mining on it.

I also read that card actually has two different BIOS chips, one with a "Boost" BIOS that sets the clock to 1411MHz, and a "Silent BIOS" that sets the clock to 1340 MHz. I will try to set it to silent bios to see if that takes care of those 10 extra watts.

Hi @Imprecision,

New forum member here. I've just got myself a refurbished Dell Precision T7810, with a 2 x Xeon E5-2690 v4, 128 GB RAM, and ... a 825W PSU.
I'm planning to install a GTX 1080 Ti GPU on this system - the exact GPU is EVGA GeForce GTX 1080 Ti SC Black Edition GAMING.
In terms of disk storage, I'll also install an M.2. NVMe adapter for PCIe 3.0 x4 lanes and a 2TB NVMe SSD on that (an SK Hynix Gold P31).

According to this GPU's specs (available here and here), it's expected to draw 250W max power, distributed via 1 x 6pin + 1 x 8pin connector.

225W can be supplied as: 75W from the PCIe 3.0 x 16lanes port, plus another 150W from the provided PSU's distribution board / edge connector.

The question is then: Where to get the remainder of 25W (aka 10% of GPU's total power requirement), in order to get to 250W max?

And while browsing the internet to look for answers, I've discovered your posts here, on this forum.

So, I was curious: For your Radeon Saphire GPU's 235W power needs, do you happen to have a status update on your project / endeavor? Did that "COMeap 8 Pin Male to Dual 8 Pin(6+2) Male PCIe Power Adapter Cable for Dell T3600 T3610 T5600 T5610 T5610 T7600 T7610 5810 T5810 T7810" (still available here), or this other similar variant named "Corsair RM Series 8 Pin to 8 Pin and 6 Pin PCIE Modular Sleeved Cable" (available here) work in your case?

I've also discovered an rather unusual configuration, described on this reddit forum:
https://www.reddit.com/r/nvidia/comments/6ieqpu The Nvidia Titan X seems to be a Pascal architecture (like GTX 1080 is) and also uses an 8pin + 6pin AUX power connector, thus suggesting a similar max power draw like mine - of about 250W.

Would you think that the rather unusual configuration described by that person on reddit would work in my case?
His use case / workload is Machine Learning, and he was saying in his original / first post (available here) that he wasn't able to achieve full stability with the original 1 x 8pin male to 2 x 6-pin male Dell-provided standard cable, coupled also with one of those 6-pin male connector into a 6-pin female to 8-pin male cable adapter (to satisfy the 8pin GPU card's connection), and with the other 6pin connected directly into the second, 6pin, GPU card's power socket. But then he apparently managed to solve the problem, and hence his 2nd, follow-up post to that.

See also my comments to that 2nd / follow-up post of his.

I'll receive my GTX 1080 Ti tomorrow, and I'll test his idea. Probably I'll have to use some free benchmarking software, to make sure I can stress the GPU to the max. Btw, what benchmark app would you folks suggest to use for that? I know only about BurnInTest. But I've heard about this "Furmark" thing - would it fit the bill for such max stressing?

If his idea proves to be unstable, I'll probably have to connect the existing 2 x 6-pin male connectors (labeled "P10" and "P11") into a 2 x 6pin - to - 8pin adapter and then draw the other 6pin from a separate 12V rail, for example from the spare SATA power cable that I have in the front / 5'' bay (and from which a mini-SATA power connector draws also power, for the DVD-RW optical unit which I have, and I do use), or from one of the two SATA power connectors present in the 2 x disk trays at the bottom of the case (to the right of the PSU), and which I wouldn't need (or maybe I'll need just 1 of those 2, for example for a spinning/mechanical HDD). Such separate power draw (of just 25W) would probably be made via a 1xSATA-to-1x6pin cable like these ones:

My only suggestion if it doesn't work/stable which I'm betting it won't be a problem is an external GPU enclosure. Never used one personally but I always see used ones from Dell Alienware systems for sale on eBay.

 

[lexluthermiester]

I must be lucky because it seems like i have such a heatsink even if the processor is smaller. My look like this. Is W3680/W3690 a better options?

BTW, forgot to respond to this. Flip your CPU heatsink to face the opposite way. Then buy one of the Arctic fans mentioned earlier and mount it to the flat side of the heatsink blowing air through the fins toward the back of the case.

 

[smihaila]

It looks like the rather unusual 2 x 6pin + 1 x 8pin cable inversion idea works. The GTX 1080 Ti is holding strong, and according to both HWMonitor and GPU-Z, it is drawing about 270W in total.
I've put it to stress tests using these 5 apps:
- Furmark (I've heard that actually, it's not exercising everything from a GPU; mostly VRMs; and sometimes that can stress to dangerous limits)
- Unigine Superposition
- Unigine Heaven
- Unigine Valley
- 3DMark's basic/free test named Firestriker.

Now, if only I could make the card's temps running lower ... It's running quite hot - 50 degrees C on idle, and hitting 91-92 degrees C on max load, and fans ramping up to max (4,000 rpm) and unbearably noisy. I've tried EVGA's "Precision X1" app, to fiddle with fan curves and "Voltage / Frequency Auto Tuner", but effective improvements came up from that.

I've even set the T7810's fans' curve to start at 30% - thinking that a lower ambient case temp / better air flow, would help the GTX 1080 Ti running less hot.
But no luck so far. So I'm stuck with a hot furnace and ... a jet engine.
Since I don't have time to fiddle with thermal paste, I've contacted the seller (e-bay), to return it. I hate hot furnaces and unbearable noise in my PC workstation...

Thank you.
