Throttlestop overclocking Desktop PCs

[sepheronx]

Retro, now that my T3500 is setup with the W3680, could you guide me through over locking with throttle stop?

Cpu temps are great after adding on the fan to the cooler. 29 celcius.

Gotta silence that fan though. It's loud even for being a "silent" fan.

Unclewebb goes through overclocking that CPU starting on page 4 in this thread.
There is no direct Voltage control. You need to turn up Turbo Power limits, and Turbo Current limits, and Turbo Ratio limits also.
Unclewebb is the developer of TS so he's the real expert here.
If you click Options you get a 2nd page where the good stuff is.

Gotta silence that fan though.

You can adjust the voltage and fan speed by using different colored wires from any 4 pin Molex connector within your case.

If you need any help with overclocking just ask. The posts back on page 4 should guide you in the right direction. Overclocking the W3680 with ThrottleStop is about as easy an overclocking project as one will ever get. 4000 MHz should be stable and 4133 MHz will probably be living on the edge of stability.

What Unclewebb is referring to is using 5V.(red) for a GRD so the fan runs on 7V. So +12V. to +5V. =7V. to slow the fan down.

Is there any way to overclock the e5-1620/e5-1650 or the e5-1620v2/e5-1650v2 on the Dell T3600/T3610's? They are becoming cheap enough to create awesome gaming pc's for flipping locally.
EDIT; or even the i7-3930K

If the CPU is unlocked then Throttlestop should be able to overclock it. Unlocked Xeons are an unofficial thing. Generally if there is an unlocked Consumer CPU there's a good chance the equivalent single CPU Xeon is unlocked also. But the Xeon could be based on an older locked version if the unlocked was released later, so not always. No one here has tried that system yet. The X58 systems with 3 channel DDR3 RAM is hanging in there when overclocked.
Here's a thread on unlocked Xeons.
https://forums.servethehome.com/index.php?threads/xeons-with-an-open-multiplier.15983/page-3
Here are the CPUs that people are running on the T3600. The e5-1650 seems to have the top spot for CPU performance.
.userbenchmark.com/Systemhttps://www/Dell-Precision-T3600/1882
I didn't notice any i7 running there.
I've only looked at the T3600 a little bit and I noticed it seems to be made from server parts more than PC parts. Non ATX PSU, and RDIMMs
If you can find a confirmed unlocked Xeon that will run on that system then you should be good to go.

Well firstly, Thank you for your timely and well thought out reply.
However, I have prior experience with Throttlestop and the T3500's with the W3680 and the i7 975x ES (both of which were able to alter multiplier successfully, thx!).
My issue comes from trying to increase multiplier for the e5-1650 and e5-1650 V2's (both of which are known unlocked xeons) on my newly acquired T3600's.
Throttlestop allows me to change the multiplier in the application, but the cpu does not actualize those settings. It just sits at stock multiplier according to CPU-Z. I'm a bit confused.
The e5-1650 is just a 3930K with ECC support, likewise the e5-1650 v2 being the 2011 socket 4930k. The T3500 is based on X58, the T3600 is based on X79, otherwise very similar (besides the GOLD rated proprietary power source in the T3600).
Has unclewebb just not had a chance to work out the kinks for the X79 based Dell T3600/T3610?
I truly appreciate any support you can offer!

I have no firsthand experience with those CPUs. ASFAIK those can be TS overclocked. There may be certain C state settings that need to be applied. Unclewebb still posts on these threads. But he's probably a lot busier than a retiree like myself. I have had TS need to be opened a 2nd time to apply the settings. There was a "display" mode that wouldn't apply them the first time. But that was in 4.0 on LGA775. Since you're experienced with TS you probably know that the LOCK, and UNLOCK buttons describe what they "will do" and not the state of the CPU.
If you can get a screen shot of TS up here I'm sure Unclewebb can help.

I'm very cautious about giving advice on the T3600. Crucial lists UDIMM memory, and Dell lists RDIMMs. Also Dell lists C600 chipset and not the X79.
https://www.dell.com/support/articl...e-precision-t3600-desktop-workstation?lang=en
In the T3500 X58 overclocking is possible, the T5500 X5500/5520 can only run 2 CPU Xeons and can't be overclocked. So the actual chipset can be a big factor.

The T1650 might be worth a look because I'm seeing i7 3770 runnning there getting 78% Cpu scores also. 3770K is the same 77W. If the T3600 doesn't work out the T1650 looks promising.

What Unclewebb is referring to is using 5V.(red) for a GRD so the fan runs on 7V. So +12V. to +5V. =7V. to slow the fan down.

That works but you need to make sure you use the right negative line to ground to. If you use the -12v, you be fine but if you use the -5v, you can potentially cause problems with other components in the system and even the PSU. It might be better to buy a better/quieter fan and a fan cable adapter for Dell computers.

 

[Retrorockit]

I was referring to the leads available in the 4 pin Molex connector. I guess I didn't specify that. +12V. to +5V.=+7V. to the fan. The +5V. is used as the GRD.

 

[HSADJADI]

X79 is c600, same silicon. Just ECC support and SAS controller unlocked vs a x79. Right?

 

[Retrorockit]

Most of us here are still figuring out the T3500 vs. T5500 situation. TS overclocking is uncommon enough that there isn't a vast history to draw on.TS was designed for undervolting laptops. It's ability to get control of Voltage and multiplier with unlocked CPUs from inside Windows is what allows overclocking on otherwise locked computers. It's confirmed in laptops on all series of CPUs.
I started this thread to explore this away from all the laptop undervolting, and BIOS overclocking data overload that's out there already. The T3600 is new and very welcome territory. But the design philosophy changed from the previous workstations. The T3400/3500 used actual desktop chipsets so the rules were very well known. The T5500 it turns out only runs 2QPI CPUs which are all locked. The T3600 uses a workstation chipset to begin with. There are about 6 versions of the C600, and the data sheet is almost1000 pages long. If you get an unlocked CPU to run, then Windows and TS should be able to overclock. But it needs to be confirmed. If you put one together and it doesn't work post some screen shots and we'll see if we can help. There's a very good chance that you're either the first one to try this, or others have just given up and not tried to figure it out, or kept it a secret. This thread is about trying to make progress with this together.
You have myself, Unclewebb, and the guys from the Dell Workstation Owners thread to help figure it out. If we knew the answer to your specific question it would already be in the thread somehwere.
Just about everything we're doing here is undocumented. Unlocked Xeons, overclocking locked BIOS computers. There is some trial and error involved. But learning what doesn't work is just as important as what does.
BTW thanks for posting the unlocked Xeons above.

Has unclewebb just not had a chance to work out the kinks for the X79 based Dell T3600/T3610?

No one has bought a T3600 for me to play with yet. Where I live, they are still out of my price range.

The X79 and C600 may be basically the same but multiplier overclocking might be blocked on the C600. Do you have any examples of overclocking while using the C600?

Try adding this line to the ThrottleStop.ini configuration file.

LockPowerLimits=1

This might allow overclocking on X79 and C600 if the CPU and chipset both support overclocking. Without hardware to test with, this is just a wild guess. After adding that line, restart ThrottleStop and make sure that you are not working on anything important in case ThrottleStop causes your computer to crash.

TS helped me out with an LGA771-775 swap. Someone posted that a Xeon would run w/o a modded BIOS in an Optiplex 380. I owned both so of course I had to try it.
X5470 3.33Ghz does run. But the BIOS complains about it. Full fan speed until reboot F1, then select Win7. It runs at the settings of the last good configuration which was a Q9505S.
8.5x333, and 1.2000V. TS allowed me to raise the Voltage to 1.2500V. and the multipler to 10x 340 (Setfsb) for 3.4Ghz. It also saved the settings to BIOS for me. Which SetFSB doesn't do.
https://www.userbenchmark.com/System/Dell-OptiPlex-380/1942 fastest Opti 380CPU score. Almost all other Optis peak at 41%.
https://www.userbenchmark.com/UserRun/11800068 CPU ranking is +50% for single and 4 core performance. The low rating of 32% for this CPU is because it's bring compared to the many 2 CPU configurations using this CPU. I have a GTX 1060 3GB to put in it if I can get the BIOS sorted out.
My RAM score went down. Maybe SetFSB pushed me into a different latency profile?
I came across a new trick from a dual CPU T7500 overclock. SetFSB crashes the SATA controlller, and a PCIe SATA card fixes that allowing more BCLK. I can't try it on my Opti because because it was a low end version they used the same MB for the Tower, and the Desktop models by leaving off 1 expansion slot. It's the PCIe 1x that's missing.

OMG i was in my storage unit and ran across an optiplex 380!!! I have plenty of x56xx's so if i mod 771 to 775 then maybe ill finally be able to use throttlestop to its potential!

You mean X54xx's? X56xx's are X58/LGA 1366 I think

 

[Retrorockit]

Yes 2 different things. The Opti 380 maxxes out at X5470 3.33Ghz 4 core with very little OC potential. I just used TS to reach LGA771 base clock w/o the BIOS mod to support that CPU.
The X56xx series includes some fast 4 core, and 6 core CPUs. But only a few of the W35xx, and W36xx are unlocked and can use TS overclocking.
A built Opti 380 wpuld have an X5470, 2x4GB DDR3 @ 1066, and a Zotac GTX1050Ti 4GB mini which drops right in and runs off of the Dell PSU.

I will have to check if I have any x54xx, i thought they were x56xx. But i have a zotac 1050ti 4gb and 4 gb ram so im good there.

 

[Retrorockit]

Since there seems to be some interest in the Opti 380/X5470 I went ahead and stuck a bracket modded MSI GTX1060 3GB, and a 375W Dell PSU from an old Pentium4 Mid tower in it.

Thanks for posting... I will be sure to run the user benchmark for my OptiPlex 380 systems. I have one with the 1333 FSB mod (thanks retrorocket) and another that is stock which should make for a good comparison.

 

[Retrorockit]

Here's my Geekbench 4
https://browser.geekbench.com/v4/cpu/10619079
I think the E7500 tapemod willl kill me in single core, and I'm one of the highest already.
BTW I totally borked the BIOS mod part of it. I'll need to start over there. Not a lot of support available for modding the Dell BIOS. You can get pretty close by running a CPUID 1067A LGA775 CPU to get some friendly setting loaded, and then tweak with TS. Definitely a work in progress. The GTX1060 cheered me up after I killed it and had to reset the BIOS to bring it back to "life". I'm still using it to post here, and running benchmarks, but it's a PITA to wake it up now.
The BIOS mod that's out there just changes the platform identifier from 11 (LGA775) to 44 (LGA771). It uses the existing 1067A microcode. This adds :GA771, but removes all LGA775 support.
The part I had trouble with was they use a utility for SysAdmins. to load BIOS updates remotely over a network. Not what I'm used to.

This is actually kind of funny. There is a whole thread (OK it's a small one) about Optiplex 380 gaming machines at OCN.
https://www.overclock.net/forum/237-htpc/1624913-dell-optiplex-380-into-modern-gaming-machine.html
I thought I was the only one running one of these bottom feeders.
But I still miss my 3.72GHz Dimension E520 QX6800 R9-285 rig. The validation link below is for 3.98GHz but that was just a validation run.
If you look at the date it was posted you'll see it was in 2nd spot for a very long time. 3.72 was good for 3rd at the time, but other users with a single clock faster fsb have pushed me off the chart.

That's what gave me the TS overclocking bug.
Here's a 3.72GHz Dimension E520 TS overclock. I know the guy from Tomshardware. Same CPU score as X5470 Opti 380. Those orignally came with Pentium 4 CPUs.

Im having a wierd TS issue on a t5500. I just loaded windows 10 64bit fresh. I did the updates and i installed the latest TS. I try and run TS and i get a bunch of dll issues. Im painstakingly running TS writing down the dll error, copying the dll from my t7500 into system 32, rebooting and starting over again to find the next missing dll.

Is there a faster way or a list of dlls?

Im excited because Im using W5590 ES and Im hoping i will have access to the multiplier.

Ill grind it out one dll at a time but if there is an easier way, please let me know.

 

[Retrorockit]

I'm afraid we've found that the T5500 only supports 5500, and 5600 dual CPU Xeons. Even in single CPU mode. Susquehannock was kind enough to test this for us. None of the 5500/5600 are unlocked multiplier. Only the W3570,W3580 4 core Nehalems, W3680 s, and W3690 6 core Gulftown/Westmeres ( and their i7 equivalent) are unlocked LGA1366 CPUs. SetFSB may work, and a PCIe SATA host card may unlock some potential there. But the T5500 has turned out to not be a good TS overclocking platform. TS may be looking for some code for the single CPU chips that doesn't exist on that platform.
But of course maybe this is what it will take to make it work? My suggestion would be to pick up a cheap W3570 and see if the dll dance can get it to run. TS overclock so far is only going to happen on a single CPU chipset (ecept QX9775 LGA771 Extreme CPU).
Even the unlocked dual CPU LGA1366 EVGA Classified SR2 only supports 5500, and 5600 Xeons. So it's probably an issue with the 5520 chipset

Technically these arent w5590s, they are Q1QW ES chips so Im thinking they have a shot of being unlocked. Im grinding through the DLLs but likely going to take a break and start up again in the morning. Ill keep you posted.

 

[Retrorockit]

I've seen reports of W5580 being unlocked by reviewers, and seen some CPUZ validations that made it look like they were multiplier unlocked. So keep up the good work.
It took me about 6 months to get my E520 overclocked. Nobody knew how to do it. I was struggling to get 3.45GHz stable. When i found the problem it went straight to 3,72GHz stable and 4 GHz validations. All the little things I had done along the way really added up of when I found out the fan speeding up took power from the VRM. 3.4A. Fan wired to Molex and all hell broke loose!

I'm going to stick an OT link in here of another project of mine. It has to do with coffee. My post is in the I made it section.
