Throttlestop overclocking Desktop PCs

[unclewebb]

I'd gladly let you remote into any system I have

I do not think I need to do that at the moment but I definitely appreciate the offer.

My bios mod skills are zero. Just looking at your screenshot I know I could have a lot of fun in there but I have never done any bios mods to my own computers. I will just tell you what I know about that register.

There used to be a rumor that I believe Intel might have started that setting that register to 2048 (2048 / 8 = 256 Amps ) would tell the CPU to ignore this limit. I have never found that to be true. It might be true on some Intel processors but on my 10th Gen, if I set that register to 256 A, I still get lots and lots of EDP throttling when running 10 threads of Prime95 Small FFTs.

On newer CPUs, Intel changed the name of this register from the PP0 Current Limit to Power Limit 4. It is the same register, in the same location with the same layout. Other than the new name, I do not think this register has changed all that much.

For 2nd Gen and newer CPUs, the maximum number this register can hold is 8191. Divide that by 8 and that is equivalent to 1023.875 A. If I use ThrottleStop to set this register to the maximum value (1023) or if I use ThrottleStop to set this register to 0, either way, the EDP OTHER throttling immediately stops. A setting of 0 tells the CPU to ignore this register.

I originally suggested changing this from 0x680 to 0x980 because I thought that would be enough to give you some more headroom before throttling. You might have to go higher to eliminate all EDP throttling or it might be best to set this to 0. If you can remove the PRIMARY_PLANE_CURRENT_CONFIG_CONTROL [LOCK], that would allow you to use ThrottleStop to adjust the PP0 Current Limit. If it is set to 0 and the bios locks it, I do not think you will have to worry about this setting holding you back.

Hopefully you can try a few different settings without creating a brick. I am looking forward to your results.

I'd bet real money that you'd take to it like a fish to water.

I have a friend that's a SQL developer. Most other languages he doesn't know he still seems to be able to help me out. I'm not a programmer/developer and just have a few recent college courses which well let's just say I'm not very knowledgeable in it. So ya unclewebb with your obvious knowledge in programming and knowing the inner workings of a computer (most of my developer friends do not) you'd be great at it. Unfortunately it seems the main market for it is getting around admin password set bios on a used computer someone bought. I haven't found anyone to help me in understanding exactly what I'm trying to do with this bios but this just goes into the reason I'm doing it. It's interesting to me and I'm having fun. Eventually I'll figure something out and maybe 4 people will care that I did lol.

Hi buddy, I am working on a project that will extensively use LGA775 (and Socket P) processors (mostly Core2 but some newer NetBurst models as well). Can Throttlestop modify the multiplier of locked CPUs so that they could all be set to the same frequency?

For clarity, I don't wish to overclock, but instead reduce the multiplier to reach a nice round frequency, such as 2.00 GHz, and I'd rather not alter the FSB through BIOS overclocking (or underclocking in this case) as that can alter the results.

I've seen Throttlestop work perfectly for my needs with my Socket P system, but I was wondering whether I could do the same with LGA775 processors as well?

 

[unclewebb]

I do not have access to any older hardware for testing purposes. ThrottleStop should still work OK on all Core 2 Duo and newer CPUs.
It does not support the older Pentium 4 based CPUs.

Thank you, my friend.

I'm assuming the CPU merely needs to support EIST for it to work, which would make sense.

If anyone here has an LGA775 system lying around that would be willing to test it out for me, I would be most grateful.

 

[unclewebb]

LGA775 system

A big chunk of ThrottleStop was developed on my Core 2 Quad, QX9650 while using Windows Vista. These old Quads were actually 2 completely separate Core 2 Duos set side by side under the heat spreader. ThrottleStop has a special feature so you can run each Core 2 Duo within the Quad at a unique speed. ThrottleStop definitely works with this old stuff.

If you are using an older operating system, you might need to find an older version of ThrottleStop that is compatible. The most recent versions of ThrottleStop no longer work on older operating systems. TechPowerUp has a good selection of older versions of ThrottleStop available for download.

Hello I think I am a bit late to the thread but I own a Dell Percision T3600 with a Intel Xeon E5-1607 0 is this configuration tested with throttlestop yet?

 

[unclewebb]

Xeon E5-1607

I think these CPUs are locked down by intel. Post some ThrottleStop screenshots to jog my memory. Let's have a look at the main window, the TPL and TRL windows.

You're correct, they don't even have a turbo clock. Plus being on a T3600 it's most likely not gonna go anywhere.

TS can still lock the all-core boost clock can't it?

Are you sure?
EDIT: Yup, you're right, that model has no boost clocks.

First off, welcome to TPU! That CPU you've got is a bottom tier model. You should get an E5-1650 and give yourself a serious upgrade. Also, ThrottleStop can push the performance of a 1650 even higher.

Both $15USD and both from sellers that have excellent feedback.

Both are very inexpensive. 2 more cores, running 200mhz faster and with an 3.8ghz boost over your existing CPU.

And you should be able to get a heatsink from a T7810 which is actually very well designed, large and has a shroud to help cool the vrm. If you want to clock a 1650 up a ways it will need more cooling. Beats the hell out of modifying a bunch of stuff to make something else work as it should just bolt right down. Also very cheap.

Also I have never played with 1st gen e5 CPUs but with a t3610 I played with an e5-1620 v2. And I believe all throttle stop can do is get the limit reasons removed. This can help performance..... slightly. And obviously I know that with a 1650v3 you can clock the hell out of them providing you can keep it cool. I'm very curious how well a v1 can be clocked.

The heatsink they have currently will be fine. Both parts are 130W TDP rated parts.

This is the heatsink the vast majority(if not all) of the T3600's came with;

If the 1607 does not use any turbo boost then there is nothing for ThrottleStop to lock.

Hopefully @Dell Percision T3600 can post a few ThrottleStop screenshots just to see what options are available. Probably not much.

 

[lexluthermiester]

As mentioned above, yeah, I saw that. Had to look up the specs to remind myself that model was one of the few V1 Socket2011 Xeons that did not have boost.

Probably not much.

That would be my guess, which is why I posted a few examples of an easy, inexpensive but solid upgrade for their system.

There is a learning curve with doing this and I will do what I can here to help with that.
1- Throttlestop sometimes won't save setting unless you open the program twice.

Yup, thanks for the *save twice* tip.

Sorry maybe it's fine. I just know since I still have my kids Dell running an e5-1650v3 CPU with a stock heatsink that I can run 4.0ghz but past that thermals run away. In my machine with the other heatsink I could run that CPU at 4.7ghz.

Side note for new comers to dells and throttle stop. Remember you may have to do a sleep/resume cycle prior to opening TS to let it do pretty much anything. Also playing with the voltages to get the powercut to work. Then your just left with a current limit in the bios that I can't defeat lol.

Not sure if this thread is still alive but here goes. I resurrected this T3500 of mine with a 750w psu, an ssd, 2 m.2 drives, 24gigs of 1333mhz ram, a 3060ti and a w3690. Mods I’ve done so far and plan to do in the near future are adding a fan to the cpu heat sink, adding a fan to the northbridge and I slapped an m.2 heat sink on the VRMs. I may or may not opt for a thicker heat sink tho. Ultimately I might just watercool the whole thing as a project if I wake up bored one day.

Using throttlestop I immediately went for a 4.1ghz overclock, it seemed stable at first but once I booted up a game it would crash after a couple minutes. So after stress testing with p95 and gaming for hours it appears to be stable at 4ghz with a 150 TDP. Any lower and it would start to throttle during p95 stress testing. Temp maxes out at 69 degrees, HT disabled.

My only problem right now is that CPUz, HW monitor, task manager and throttle stop shows the 4ghz overclock but msi afterburner doesn’t. It show 3600mhz. So I guess the question is, any idea why and how to fix it? And also is there anyway to get a higher OC that’s stable with such limited access?

 

[unclewebb]

@Fortis91
Changing the CPU speed while in Windows on these old CPUs screws up some monitoring software. You will have to ignore Afterburner. Go by what ThrottleStop and CPU-Z are telling you.

Without any CPU voltage control possible, 4 GHz is the typical stable limit for the W3680 and W3690.

My W3680 was TS Bench stable at 4133 MHz but would crash in more demanding tests at that speed.

Yes, but not on my mainboard :D Thats the problem. Otherwise the x5650 would be enough. That was general information to help others who may want to try this. They are socket 1156 CPUs. When I first posted that I wasn't aware the i5 655K was 2 core so I added that info as a clarification. The...

Your photo doesn't show the HDD tray installed. It provides a ducting from the system fan to the CPU cooler. Something to cover the gap there might help.
The 90x38mm Nidec M35105-57 fan was used to cool old 130W Pentium D CPUs. It's not PWM so 12V. will make it run. It speeds up when the air gets hot off of the CPU heatsink.
Mangupta used one in this thread for cooling in India at 40*C ambient. Maybe you can squeeze a little more out of it.
Dell fan controllers are known for too little too late. HWInfo64 can bump up the fan speed profile some.
The thread is still alive except not too many people seem to be doing this anymore.

There is a site called greenpcgamers that is just about building old workstations. I thought it would take off and I wanted to contribute. I've come to realize very few of us care. Sorta sucks because there are a lot of these old things going to waste and they are still very much useful by today's standards. On that it doesn't matter what I need to do on my PC. I boot it up and get TS going. Might as well have a bunch of fast cores to respond to someone's email lol.

Yeah I've contributed to that site as well. The value in these workstations is sometimes impossible to beat because of things like cheap ecc reg ram, great factory power supplies and lots of ports and slots for beefy setups. But like you said, doesn't seem like the mainstream cares--and actually that's a bit of a good thing because otherwise the prices would increase due to demand.

Hello, i'm not sure if my post belongs here, but i've a 12th gen i7-12700KF that i've just upgraded to on a rather decent B660M motherboard (it had a 12400F previously and i got the 12700KF for cheap, sealed).

I was wondering whether i can do all core turbo overclocking using Throttlestop since it seems to be unlocked and unlimited in the software? Would TS be able to overwrite the B660M limitations when it comes to any form of overclocking?
