Throttlestop overclocking Desktop PCs

[Retrorockit]

That would be very interesting. Especially if it translated to the T5500. Some of us like that MB for T3500 swapping. W3680 is about as good as it gets. I'm not sure there's any real advantage to the W3690.
FWIW I went to Userbenchmark and looked at all 1300+ examples of T7500 and the only W series I saw were some W5580,W5590. So no examples in the wild. Yet.

I came across this Spectre, and Meltdown patches for the T5500,T7500. Nothing for the X58 systems.

In reading i though someone said the got a x5670 to 4ghz (maybe a different method?). Anyway no harm in trying, ive got a bunch of x5600s and plenty of time on my hands.

But anyone try yet with t7500s...or the Nhlm E5500 series processors?

If Im stuck with the X5687 and x5690s stock it wont be a total loss. I ran a firestrike1.1 test with a pair of stock x5670s and an rx580 and my score fell with 1% of a current i7/i9 with the same gpu, so no real bottleneck there.

There is one way to get a dual CPU overclock. No one here has spent the money to do it yet. But the EVGA Classified SR2 is an unlocked dual CPU LGA1366 motherboard.

Hah Ive been looking at them (SR2 Classified)!

But Ive also been playing around some with what I have, to get some results.

So I started with my current desktop -
T7500, 2x x5680s - air cooled, 48gb ram, 256gb intel enterprise ssd, EVGA 1070ti SC Hybrid 8gb

I ran some simple video benches:

time spy 1.0
https://www.3dmark.com/3dm/29490101

firestrike 1.1
https://www.3dmark.com/3dm/29490687

if you compare to a non -OC
i7-6700k
https://www.3dmark.com/spy/4641982

Its pretty similar (though they are using an slightly different 1070 TI EVGA GPU if you look at the clocks).

I tired throttelstop, cores were locked but I could go to 26T multiplier but didnt see a change.
I tried the Intel Extreme Utility - all locked
I tried set FSB and it only increased processor 2 ??? I scored a top 3.58ghz with these settings if you look at the extreme utility bench but if you look at cpuz the processor speeds are different.

So I'm getting somewhere..maybe, while also getting nowhere? Confirmation - throttlestop wont help dual x5680s on T7500 board...but setfsb nets a little gain...but for what price...

I backed everything down and will be playing with a T5500 for the rest of the testing as its easier to move around (half the case size/weight). Or I may use an open board (no case) setup T7500 I was using for mining...we shall see.

The only thing I find annoying about the T5500 that if you run a full size GPU and its powered from the TOP, you lose a drive bay. If its powered from the rear then its no issue. You also have to strip out the blue pci card separator, but no loss there.

I will start trying all the other combos shortly.

But something interesting to note on the T7500 - I was able to pull the rear case fan out and seat my GPU cooler fan in the area just next to the riser. It was a tight fit but all is running well. (Pictures will come)

Also, I ordered a dell 5 pin fan splitter. I plan to use a fan cooled riser heatsink on CPU 0 on the motherboard and then connect both fans to the riser port so as CPU temps increase both will be direct fan cooled. I was going to plug it into the rear case fan slot but then it wont turn on the fan according to cpu heat as easily. I may just try and jumper out the rear case fan or install the fan elsewhere like in the 5.25 bay where I currently have an evercool for my 6tb raid array to get rid of the annoying boot error. (Pics to come)

SetFSB has a hexadecimal editor in it. There is a way to reset the FSB lock bit. I have 0 knowledge of Hexadecimal, and haven't found a text to learn it anywhere. But the value 9 locks it and 6 unlocks the PLL chip. Which register get's changed I haven't got a clue. There is probably a way to associate it with the different CPUs also. It would probably need a 2nd instance of it running.
Another utility is RW Everything. I have no idea how to use it. But it looks like it can edit just about anything including 2ndary RAM timings.
I came across this stuff here.

Maybe you could try overclocking a single CPU then add the 2nd and see if it somehow matches?

There is only one unlocked LGA771 CPU the QX9775. it is also the only unlocked dual CPU processor. Unlocked CPUs are rquired for TS overclocking. If you have a MB with an X38, or X48 chipset then there's a pinmod to 400fsb that should get 4GHz on an X5470.

 

[Retrorockit]

There's T7500 thread at OCN you might want to look at.

So I came across the dell client configurator today looking for a way to change the asses tag (like Asset_A209.com did for older 32bit systems)

Software:
https://www.dell.com/support/home/us/en/04/drivers/driversdetails?c=us&l=en&s=biz&driverid=R304287

Manual:
http://wikifoundryattachments.com/AVs0Or3N0zyuxf+oBrGNbg==764439

It basically allows you to command line edit (or gui - limited) the Dell Bios.

For instance you can change the asset tag using :

EXAMPLE
"cctk --asset=ASSETTAG"


It also allows to to enable the amount of cores to use per CPU and Bus Ratio in CPU!

I'm wondering if they just left the info out the manual for "set core voltage" or "set core multiplier" but its somewhere in there if you can find the right syntax. I found you can read the current cpu speed using "cctk --cpuspeed"

Anyone ever mess with this program???

I guess I should expand on this a little bit more related specifically to the T7400.
The T7400 supports the 400FSB LGA771 Xeons. The T5400 doesn't. The pinout of the LGA771, and LGA775 CPUs is the same for BSEL, and VID pruposes. The maps look different because the notches for the socket are in different places. But you'll notice that the pins are marked reserved where the notches go in the other CPUs. So even if the T7400 doesn't have an X38, or x48 chipset it does support 2 CPU and 400fsb so the pinmod should work if you adjust it for the LGA771 pinout. The VID pinmod which is more complex should work also. I was buying parts to try this but someone is buying up all the workstations locally so I never got my hands on one.

Here's a $5 build I did quite some time ago that relied on Throttle stop...the PC was not officially supposed to support 45nm cpu, fixed that with a microcode update...still only dual cores allowed, but got an e5800, BSEL modded to 1066FSB, booted into Windows at 4.2Ghz and used Throttlestop to drop the multi to 15 from 16...which resulted in stable 3.99GHz e5800 paired with 8600 GT volt mod 900 core...got everything for under $5. Just thought I'd share here since this seems to be a little different than the typical things Throttlestop is used for.

 

[Retrorockit]

My Opti 380 came with an E5800. I tried the tapemod and no go. I had a pile of CPUs so I just moved on to the next. QX9650 didn't work either. Q9505S was the next choice. Mine didn't boot at 4.2GHz so I didn't get to try that. What is a fast 2 core system like that good for. I've suggested the classic E7500 pinmod to 3.66GHz many times but haven't gotten any feedback on it.

I have a couple extra e7500 CPUs what is this pin mod all about? Interested in trying it out.

It's the same as the classic Q6600 BSEL mod. A piece of tape changes the FSB from 266-333 (or 1066-1333 @ CPU). A Q6600 SLACR would go to 3GHz on the stock Voltage.
http://www.tomshardware.com/answers/id-2125877/tape-mod-bsel-mod-intel-q6600.html The 2nd photo is the mod.
The E7500 is 1066 FSB also and can usually sustain 3.66Ghz. If you can raise voltage then the E7600 can go higher.

Thanks. I just tried this mod on my Dell OptiPlex 350 workstation with excellent results. I used an e7500 and netted 3.657Ghz at stock voltage and all appears to be well. Next step is to try this on a Q6700 and see if I can get 3.333Ghz in my HTPC.

 

[Retrorockit]

Q6700 are nice chips. All of them are G0 stepping and overlooked by overclockers who obsessed over the cheaper Q6600 G0 back in the day. If a computer supports 1333fsb but not 45nm CPUs then it's a good way to go short of a QX6800 SLACP. The QX6700 are all B3 stepping and pretty lame.

Good to hear. A have this HTPC that's been work in progress. Initially, I had the bios modded to except the QX6850 but she ran a little hot and for some reason I could not use ThrottleStop to overclock from within Windows. After that, I replaced the CPU with a Q9450S and temps came down substantially. I think the Q6700 is next up on my short list of processor acquisitions! I will probably start a new thread or blog when the time comes to install the chip. Only a few select Core 2 chips ever came with a 10x multi that's one reason I just love it.

 

[Retrorockit]

I've run the QX6800 G0 with TS to 4GHz in a Dell Dimension E520.
http://valid.x86.fr/bg4n0r
The base multi on the QX6800 is 11. The X6800 2 core is also but it's B3 stepping only.

So here is my failed testing:
(as unclewebb already advised they wouldnt work - I wanted to try anyway...whats a few grams of silverpaste eh?)
I turned off hyperthreading so that I could control all 8-12 cores on the 2 processors.

T5500 A17 - CPU Pairs:
X5687 - Locked Only allowed +1 multiple

T7500 A17 - CPU Pairs:
X5670 - Locked Only allowed +1 multiple
X5680 - Locked Only allowed +1 multiple
X5690 - Locked Only allowed +1 multiple
X5690 ES - Locked Only allowed +1 multiple (but ES showed up/runs in dell bios with no issues)

T5500 A17 - Single processor:
X5650 - Locked - Only allowed +1 multiple
X5675 - Locked - Only allowed +1 multiple

Still to test :
W5590 ES - Pair
W5690 ES - Pair
And I plan to buy some W5680 as it was listed in the T7500 A04 bios as supported

I honestly didnt think the ES and W chips would work ina Dell T5500/T7500, so thats why I left them to the end, but with the X5690 ES at least showing up in BIOS it is promising.

I lave a lot of the e55xx and about 8 pair of x5687 but probably wont test them unless someone has a direct request.

 

[Retrorockit]

Thanks for making it official. A few people tried a few of those and failed. It's looking like the dual CPU machines only support dual CPUs, and none of those in LGA1366 are unlocked.
It's too bad because the T5500 has a lot going for it as a TS OC platform

 

[unclewebb]

If you want to access the highest multiplier on a locked CPU, you need to have at least the C3 C state enabled in the bios. CPU World is a good source of info which shows the maximum speed when the C States are enabled.

http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon X5670 - AT80614005130AA (BX80614X5670).html

Appreciate your testing. My nephew is a proud new T3500 owner so maybe this winter if I get bored and the price is right, I will try a T5500 or T7500. Fun toys to play with.

Well I still have the W chips to try..we will see if they work in 1 or 2 cpu configurations.

Very good to know I will explore the c states more. I saw the CCTK/DCC dell bios tool does have some options in there. I dont know if it will get me where I want but I'll see whats possible.

Also I love the T7500. It is so big it makes the T5500 look like a toy.

The case has 4x 3.5" internal drive bays + 4x 5.25" bays. I ran two 1070ti graphics cards on 16x channels with sli bridge all off the stock power supply. I now run a single watercooled 1070ti to keep it quiet and was able to fit the watercooled fan where the rear case fan was.

If you interested in multiple harddrives, raid, multiple GPUs, 192gb ram, etc the T7500 allows for a lot more than the T5500. And if only we can find a way to OC them....They have plenty of room for watercooler gear inside the case!

 

[Retrorockit]

The T7500 has a taller CPU cooler than the T5500.

 

[totalfreq]

Are you joking since the box is bigger?

Do you mean the heatsinks?

All mine are the same size so I'd be interested to know which one's I'm running incorrectly.

Unless you mean the front fan assembly is larger. Because Im pretty sure it is.

 

[Retrorockit]

With the HDD cages moved to the PSU end of the case there is room for a taller heatsink. I think this is it.
https://www.serverworlds.com/dell-u402f-precision-t7500-primary-heatsink/
Some places sell this for T3500 T5500 also but Susquehannock says it's too tall. U016F is the smaller one that came with my T3500.
If you scroll down that page you will see several heatsink options. What they put in them depends on what CPU they were ordered with.
There's probably plenty of room for the Shuriken Ninja 4. But I had to use a Thermalright hardware kit to mount it to the Dell MB.

I never saw those before - my T7500's came with the aluminum ones so I upgraded to the U016F (on all of my machines). I pushed the 95W and 130w CPUs pretty hard for several months the beginning of this year mining Electroneum on all 24 threads and my CPU heat never became unmanageable (just my powerbill). I swapped my worstation primary heatsink with a riser one just for fun...in hopes of Overclocking but for now it was not needed.

Also when I took off the CPUs to test this week the paste was still in good shape so they were definately not cooking. Interesting find though on the larger heatsinks, but I have to say at stock clocks the smaller heatpipe ones have done just fine under continuous full load.

 

[Retrorockit]

The U016F is all the T5500 came with for 130W CPU so it's good enough. Everyone seems happy with a fan added to the T5500 cooler.
I have a huge colllection of Dell heatpipe coolers. If I see one that looks interesting and it's cheap I grab it.
FN654 is the big cooler for the T7400 that most people haven't seen. 8 heat tubes instead of 6. It probaly had to have a 400fsb CPU to get that cooler.
https://www.serverworlds.com/dell-fn654-precision-690-t7400-heatsink/
FD841 is more common and has a larger center heatpipe. So who knows which is actually better?
https://www.serverworlds.com/dell-fd841-precision-690-t7400-heatsink-w-screws/
W041K is an LGA1366 XPS 730X cooler. 8 pipes and an exhauust fan. I don't have a T7500 to try it in. Made for overclocking i7-990X.
