Throttlestop overclocking Desktop PCs

[J-Man1990]

The Dell should have a 4 LED diagnostic display. Are there any codes displayed there? If so see page 12 here.

Thanks ill check that out when i get home

Edit: Finally home from work. Checked the PC and no error codes what so ever

Does the BIOS give the option to untie the straps?
You may be overclocking the Pci-e as well, causing it to crash.

 

[Retrorockit]

The Dell BIOS has no useful options for overclocking. The Throttlestop method operates in Windows, and raises just the multiplier, and "Power Limit" settings that an unlocked CPU allows.
The RAM timings and PCIe aren't affected.

My girlfriend's pink fans arrived...

I've got a bit of a problem. I just bought a T3500 and a w3570 with the intent to overclock and flip it. Problem is i cant overclock it at all even the slightest bump causes it to crash. Not sure if I've got a bad cpu or something set wrong in the bios. I have a Hp z400 with the same cpu and can run at 4ghz no problem thought about testing this cpu in my rig but really didnt want to tare it down if i dont have to

That's strange...I recently added a W3570 to my T3500 setup..I am sitting at 3.86GHz...all I did was use the TRL and TPL tabs in Throttlestop and that's it.

Running a t3500 with a xeon w3570 since launch and been able to have a stable oc with a multiplier of x29(3.77gh) @75c but still able to push him to x30 {3.999ghz). Paired with a 1080ti and it can eat everything at ultra 1080p (35%load gaming GTAV at ultra everything). That thing is still running really well for being and old and "cough" obsolete "cough" hardware.

Waiting on a w3690 to be delivered and can't wait to see what i can offer. I'm happy I've found people interested in it, and also glad i didn't spend thousands more just for a little extra fps i won't notice.

I do get the alert, and actually have to hit F2, not F1, enter the BIOS screen, hit exit, it reboots, and then hit F1...not sure why, but that's how it works for me. If I just hit F1 on boot, it does nothing...either way, I still boot into Windows without the front panel board connected. Kind of a pain, I guess, if you shutdown your PC alot...I just let mine sleep and leave it on most of the day and only shutdown before bed. Also, there is probably a setting in BIOS to disable the alert...but haven't even bothered to check...I'll check next reboot and report back.

There is one, was tired of doing f1 manually during updates and the annoying *beeps*. Was useful to had the alerts on when changing my ram as it will still boot with some ram errors when alerts are disabled

Finally have the money to build my girlfriend a PC (currently uses a Mac)...thinking of going with the Z400 board vs T3500 due to it being easier to mount inside a traditional ATX case...I know the 24-pin is not standard, but someone in this thread shared the pinout...anything else I should worry about when running just the bare board sans the rest of the Z400 system? Does it boot without stock fans? Does it boot without front panel connected? If these are unknowns, I'll stick with the T3500 board and just do the same as I already have with my current setup. Also finally ordering a W3570, another 2GB stick of RAM, and an SSD for my own PC.

It does boot without the control panel. Easiest trick is to get any decent mid tower, screw every screw that you can screw (mines been sitting on 4 screws for 3 years without problem). Put a decent branded psu of your choice. Use the rear on/off button on the psu as your switch. I do need sometimes to flush all power from it to restart it this way.

Check my build in this thread...I've been using just the T3500 board in a Corsair Carbide Spec-01 since first setup. I literally just picked up a board off of Ebay and installed into this case. Running an AIO liquid cooler on the CPU. And been using the PSU rocker switch as power since I put it all together lol I did find the pinout for the front panel power button, but forget it now...I build a similar system based on a Z400 board for my girlfriend that has the proper power switch hooked up though. Make sure to let us know how it goes with the W3690 though! I am eventually going to do the same, get an unlocked 6 core for my T3500 setup, and move the 3.86GHz W3570 to my girlfriend's PC. You should share some photos of your build here!

Seems you got front USB working on the Z400, know where are the headers located on the t3500, didn't really fucked about it (too small to read) but since i see it can work... Do you have power button working? I'm using the PSU switch and tired of that, can't find the pinout layout, tried myself but never found out.

Just wondering how well it went for installing the AIO. I had to create my own custom bracket to put an CM Evo 212.

Does fans start spinning like crazy? Think might be overheating, it wouldn't OC or be at 100% load for too long time before crashing.

No the fans are normal and Ive checked the temps they get up to around 75c but thats normal (its HOT where i live) I put the cpu in my personal rig and tried overclocking and while it didnt crash instantly i could only clock it to 3.6 ghz so im guessing i just lost the silicone lottery on this cpu

 

[Aaron_Henderson]

Just now noticing the W3680 is 32nm vs my W3570 45nm...any chance the 32nm overclock a little better with "stock" vcore on a setup like mine? 30x multi would be nice on 6C/12T...

I'll be able to tell you in about a week, mine should arrive later on this week

 

[dorsetknob]

All the 32nm tend to run cooler than the 45nm so should overclock better ( cannot confirm as i only have had 32nm westmere)

 

[Aaron_Henderson]

I'll be happy if it at least does the 3.866GHz (29 multi) that my W3570 can...just hoping it might go a little farther...I can set 4GHz on my W3570, but it's not stable...though I can run a bench or two. It may not make much of a practical difference to go from 3.866GHz to 4.0GHz. but the nice round number just makes me feel better lol

 

[TechyTed]

Uncleweb posted this several pages back

...In a T3500, a typical W3680 is probably going to max out at somewhere around 4000 MHz to 4133 MHz due to the limited CPU voltage. On the EVGA board with the CPU voltage set sky high, a similar W3670 can run at 4700 MHz....

He said he leaves his T3500/W3680 combo at 30 or 31 multi. Its not stable at 32. I think thats on air cooling.

Isn't x30 3.99907 GHZ? not round enough... I can't finish most of the benches but it's stable enough for gaming, though not running it @x30 stilll

Hello guys, before i start thank you Retrorockit & unclewebb. Okay so I read through the whole thread and uncle said the westmere x56 cpus are unlocked but they have locked multipliers. So basically the only way to overclock is to bclk.I plan on building a dual cpu setup with x5675. it seems like nobody here has tried it on the forums but wouldnt it be possible to overclock the x56 series by using both throttlestop and setfsb. Do you think it would be possible to get them to 4ghz?

 

[Arjai]

So, according to Ark/Intel ECC Registered and Un Regestered (consumer) RAM are both acceptable. My question is this, or two questions are these:

Does the Dell T3500 MB accept ECC RAM?

Will using ECC Ram affect the OC-ability of the T3500, and say a w3690?

EDIT: Does anyone know, or seen anything, about the TS OC-ing ability of an X5670, Westmere?
Edit2: If I get a T 3500 w/ a X5670, will I need to switch BIOS if I get a W3680/90?

I read through all 15pages of this thread. Leared I wanted a T 3500 but, Too much info is confusing me...I tried to re find stuff but, now I am tired.

Great thread @Retrorockit I hope to get one of these Crunching numbers for me, soon!! I have been wanting a Ryzen, for all the cores, but this is a 12 thread bargain! Plus if I can clock it as fast as a new Ryzen, or better, without breaking the electric bill, thus the want of the 32nm. It could be a WIN, WIN! Plus, I get to play w/ OC-ing, which I haven't done since my Socket A days!!

Yes.

No, you'll be fine.

EDIT: Does anyone know, or seen anything, about the TS OC-ing ability of an X5670, Westmere?

TS can force all cores to the maximum multiplier, but can't change the multi above that as it's a locked CPU.

Edit2: If I get a T 3500 w/ a X5670, will I need to switch BIOS if I get a W3680/90?

No, it's natively supported. You will want to update the bios to the latest version.

 

[BouziGolouM]

Does the Dell T3500 MB accept ECC RAM?

If you want to add more ram, it's ecc unbuffered not registered (24gb), otherwise, max amount would be less.

Latest version is A17 but if you have a x5670, i think you should already have latest rev.

It is possible, seen it somewhere, don't remember where though.

One more question. Will TS work in Linux Mint, or any Linux Distro's?

 

[unclewebb]

Will TS work in Linux Mint, or any Linux Distro's?

ThrottleStop is a Windows only app.
For the 1st Gen Core i CPUs, it should be pretty easy to write a little script to overclock in Linux. The MSRs are publicly documented by Intel.

For the turbo multipliers you would need to write to
MSR 0x1AD - EDX = 0x00000000
MSR 0x1AD - EAX = 0x1E11E1E1E

That would get you the 30 multiplier whether 1, 2, 3 or 4 cores are active.

You might also need to adjust MSR 0x199. That one is the multiplier request register. For 1st Gen CPUs, you need to write the default multi + 1 to ask the CPU for full turbo boost. If anyone needs to know more, just ask me. You could also monitor those two registers in Windows with RW Everything while playing around with various ThrottleStop settings. I think the TDP - TDC are both in MSR 0x1AC, also well documented by Intel. It would be great to see Linux users having some multiplier overclocking fun too.

I will have to ask more about this another time, perhaps in a week, or so, once I can get a day off.

There are only a couple multiplier unlocked Westmeres W3680/W3690 and the dirt cheap W3570 W3580 Nehalem 4 cores. These can be overclocked with TS and mothing will change in the RAM timings. All workstations support ECC memory. It's the nature of the beast. With dual CPU workstations like the T5500 RDIMMs become a possibility in 2 CPU configurations. 2 CPU overclocking is pretty much unexplored territory so far. Ther are no multipler unlocked 2xCPUs since the Skulltrail days.

If you all figure out how to overclock in Linux, please share. I’ve done some searches and what I’ve found it is mainly talking about BIOS settings. There was an obscure reference to Grub boot parameters, but I think that is FSB tweaking.

 

[unclewebb]

If you all figure out how to overclock in Linux, please share.

I did share. For the 1st Gen Core i CPUs, you only need to change a couple of Model Specific Registers (MSR) and I posted the two registers that need to be changed as well as the location of the third register that controls the turbo power limits. All of these registers are listed in the Intel public documentation. In Linux you can download some software that will allow you to change MSR values as long as you have Ring0 privileges.

The Linux community has been reverse engineering ThrottleStop for a while now. This forum talks about the newer 4th Gen and up CPUs that use the FIVR to control voltages.
