Sometimes Throttlestop is blocked from changing the multiplier in LGA2011. Intel XTU seems to work and does control power settings. From what I've seen XTU only applies to Sandy Bridge and newer CPUs. At least the download I saw was like that. So that may turn out to be the dividing line for TS vs. XTU overclocking.
The single CPU T3610 workstation uses use the narrow ILM LGA2011 heatsink bolt pattern that the 2 CPU machines and servers use. Noctua, and Asetek make narrow brackets for some of their coolers and water block/pumps. But you need to plan for this.

I would like to thank nathna for bringing his T 3610 over here and taking a shot at this. He definitenly added something to our knowledge base and helped us get beyond the X58 barrier. Finding out what doesn't work and publishing it really helps others not waste their time. Finding something that does work is of course much more fun.
I hope he gets some cooling mods going and reports back with more good news.Most games are still single thread. Ignoring HT and ramping up 1 core may have some real value there. The benchmarks love 12T overclocks (so do I) but the "real" gaming world may have other ideas.
This whole thread below is worth a read by anyone interested in software overclocking. It's an HWBot competitor with an HP workstation @ 4.7Ghz telling how it's done.
Hello, i whant to overcklock 1650 v2 in z420/z620 v2. For start i am use XTU and it is capeble to overcklock all threads to 3.9GHz Then i find out that if i ran ThrottleStop and set multipler to 42 after this i can increase overcklock in XTU to 42 too, and 1650 v2 work in 4.2GHz. But in heavy...

In a nutshell- cooling matters. The lower temperature = lower resistance= higher clock at the SAME power.
The same applies to VRM. Better cooling = more power.
Don't be scared away by his over the top water loop. He put the video card in the loop also, which IMHO isn't needed.
Water has to be bigger than air to work because it's actually low tech. But a 2 fan 140x280 radiator and an Asetech pump block hosed together is about all that's needed to cool a CPU. But get a 2nd opinion on this to be sure. Don't mix different metals in a cooling loop.
Anyone who's seen my stuff on page 8,9 of this thread knows I'm a "big fan" of air cooling. But the T3610 doesn't lend itself to that ASFAIK. They went to a server heatsink footprint, and added 4 more RAM slots close to the CPU.
The heatsink uses an 80mm fan which needs high RPM to move any air and makes a bunch of noise "trying" to do it.
It's producing about the same OC result as the T3500 heatsink + random fan added.
This cooler is worth a (my $.02) look. Because it might not be too tall, and has brackets to mount either way.

The fans would hang out over the RAM slots, and Dell mounting hardware is "unique". I haven't had my hands on one of these systems so IDK what's going on inside those big ram covers. Noctua is pricey so there may be similar coolers from other brands. But the Noctua style is designed to clear ram slots. The Dynatron stuff sits low between them and tend to be very noisy in the smaller sizes.

Re: William P from Tomshardware re: workstation overclocking thread at TPU
William P,
I had a look at the Throttlestop site thread re: O/C of Xeon E5-1660 v2 on Dell Precision T3610.
Although I’ve never visited Throttlestop, for some reason I'm not allowed to register to the site.
If you could relay this to nantha- Thanks
nantha,
I’ve found that the Intel Extreme Tuning Utility (XTU) is very effective in overclocking the unlocked LGA-2011 Xeons: E5-1650 v2, E5-1660 v2, and E5-1680 v2, and reportedly the LGA-2011-3: E5-1650 v3, E5-1660 v3, and E5-1680 v3.
I used XTU version 5.2.0.14 (it dates to nearer to the time of the E5-v2 production) to overclock an E5-1660 v2 in an HP z420, the HP WS line similar to the Dell T3600/ T3610.
XTU is extremely easy to use as one only needs to set the multiplier value and then add voltage until the processor is stable. XTU is protective, so it will shut itself down and restart is the voltage is insufficient. I set a limit on a maximum of 1.42 volts.
In general XTU is very reliable, but I have had a very number of XTU kick-off and restarts. These always seem to happen quite near to starting the system and over time, I’ve really cut the startup menu to the minimum and plus waiting a bit longer to start work has helped.
XTU results:

The average Passmark single thread mark =

There were a few failed experiments at 4.3GHz, as the temperatures in Prime 95 were too high. The Passmark Single Thread Mark was significantly improved, but as the main office system ran CPU-based renderings, and I didn’t want to pay the price then of a new z420 AIO liquid cooler- over $200, I decided to change to the 8-core Xeon E5-1680 v2 and also needed 64GB of RAM for the main system.

A friend in the UK has a very similar system and thanks to his custom built external cooler (he’s an engineer whose company has complete high tech fabrication gear) runs his E5-1680 v2 at 4.7GHz
The second office system was another z420, used for CAD, rendering and higher resolution image editing, this time with an E5-1650 v2:
HP z420_3: (2015) (R11)

[Passmark System Rating: = 5644 / CPU = 15293 / 2D = 847 / 3D = 10953 / Mem = 2997 Disk = 4858 /Single Thread Mark =
2384 [6.27.19]
thanks to the liquid cooling, z420_3 has the highest single thread rating of any system I’ve had. The average STM for the E5-1650 v2 is
2001, so the improvement is very noticeable. As was the case for z420_2, it was impossible to have above a stable 4.2GHz on the original air cooling and any substantial load would kick it out of XTU. The key to the 4.3GHz success is the special HP z420 liquid cooler and the +150mV voltage is not excessive. The E5-1680 v2 requires +250Mv but that has an 85C rating as compared to the E5 1660 v2's rating of 72C.
The problem with workstations for high-load, all-core applications and also gaming is that the cases are made to be quiet and are don’t have as good an air flow as gaming cases. The GPU’s in WS are always one fan blower designs as multi-fan open GPU’s will heat the case and raise the heat load on the CPU. I’m convinced that the solution is to use an external cooler and have had for some time:
https://www.amazon.com/Alphacool-Eiswand-External-Cooling-System/dp/B01MDQMS1J/ref=sr_1_1?keywords=A...
I bought the 6-fan in push/pull /radiator /pump/ reservoir unit separately and uprated to all Copper fittings: CPU block, connectors and a pass through plate that takes a PCIe slot where the quick release fittings connect the external lines and the power.
I’ve never set it up though. I’m thinking that in a year or so, I may build a Ryzen 9 3950X (16C@3.5/ 4.7Ghz) Quadro RTX 4000 system as the single-thread performance is so astounding good over 16-cores- Passmark = 3005. The 3950X is known to need very strong cooling.
I think it would not be too difficult to build an external cooler along these lines using marine plywood and stock parts.
