Throttlestop overclocking Desktop PCs

[frankr2994]

Hey I'll ask before I actually do it. I'm now an admin on a discord for a site that I have mentioned on here before. My short time there I already got a few people overclocking with TS. Didn't know if I could put the discord invite up on here or not? I don't think it's really like advertising or anything since no one is getting paid lol.

It is the bracket, check picture!

I didn't want to assume that was the only problem. You can get replacement brackets on Amazon or Ebay for cheap.

As long as you upgrade to a "K" series CPU, yes. Otherwise the only thing you might be able to do is lock the CPU to it's all-core turbo.

Is there some setting for Overclocking if you have a k cpu?

"K" series CPU's are much more flexible and TS should allow for a lot of fun! Though to be fair, if you have the right motherboard and utility from the board maker, you likely don't need TS. If you don't have such a board then TS is your ticket!

No, you can't for T20...if you think you can, show me.

Also AC gives you FREE replacement bracket, if sthg like this happens.

What are you using this cooler for anyways? I'm in the 200watt area overclocking a xeon. My 60ish dollar modded supermicro cooler keeps me in the 70c range stressed.

I bought them for some old X3360, but use them on Linux based Q9550S instead.

Also, I do not trust Supermicro, as several MBO failed on me. Those shit are not in my systems anymore! Only Intel's.

I'm not going to flame you for LGA775. I like them and still use them. But the starting point for TS Overclocking is a MB that supports 130W CPUs with unlocked multipliers.
Basically QX9650 for the 45nm architecture and SSE4 instruction set. Many locked OEM LGA775 MB have a 95W CPU limit.
I would suggest a Dell T3400 workstation with the T9303 heatpipe cooler. They'll hit 4.15GHz at userbenchmark.com It's BTX so you're completely immune to Coolermaster issues.
TS is a Windows program. So Linux rules this out also. You can't even undervolt your Q9505S which would be kind of fun to do.
Mine is 1.1000V.=46*C on TSbench 100% load. My 150x50mm Delta fan doesn't even speed up for this CPU.. Undervolted 10% maybe 60W?
I don't recall exactly what my 120W Xeon X5470 did in the Optiplex 380. But I don't think it went much over 60*C under load.

It's in a Dell t5810. And I don't even use the fan that came with the cooler. My supermicro cooler has the hold down bracket modified slightly to use the Dell screws. Fan is replaced with an additional front panel fan. 90x35 I think. Really high rpm high pressure fan. I can't fit anything bigger in my system so as far as an air cooler goes this is about top shit for it.

Ran overclocks on my 8 core again the other night. Tried my hand at overclocking the cache as well. I can do 4.3ghz all core turbo with hyper threading on and 3.6ghz cache. Voltage at 1.20 each. Getting the cache clocked up from 3.0ghz really pours on the heat. Temps were about 79c stressed. And once again if I go to 4.4ghz I hit edp current limit. If I try 3.7ghz cache system freezes regardless of voltage. I ran cinebench r23 for an hour with 4.3/3.6 no issues. Calculated wattage (since I can't see it due to using powercut) is 250 watts.

Hey still playing around with this. Can anyone tell me what the throttle limit flag "PCS LIMIT" is?

 

[unclewebb]

@frankr2994

I can show you the Intel definition for PCS throttling but no idea what it means or how to correct this type of throttling problem.

Platform Configuration Services Status
When set, frequency is reduced below the operating system request due to PCS limit

Lol. No need to correct. It happened when I tried setting CPU cache frequency and voltage way down in an attempt to get current headroom on the core clock. I just couldn't believe I set a limit flag I hadn't seen before. Thanks for letting me know what it stands for even if we have no idea what it actually is lol.

Hey I found some info earlier in this thread on someone giving it a go with a Dell t3610. They mentioned it took forever to get the multiplier unlocked but didn't go into any detail. Anyone know what maybe needs to be done?

I believe the C States need to be disabled in the bios for the OS to have direct multiplier control. Those settings are either in "Performance" or "Power Management".

 

[unclewebb]

the C States need to be disabled

Disabling the C states prevents Intel turbo boost from working correctly. I would avoid doing that.

 

[frankr2994]

Well I'm assisting someone with this project. The sleep resume cycle like what works on my 5810 did not unlock the multiplier in TS.

Not that I've seen. In Dell systems, turbo boosting is completely independent from the c-state functionality. At minimum all-core turbo still works properly.

CPU is an e5-1650v2

Oh! There's the problem. The 1650 is not unlocked. Only the 1660 and 1680 are unlocked, AFAIK. They need an upgrade to use TS properly.

EDIT: Or I could be wrong...

Intel Xeon E5-1650 v2 Specs

Ivy Bridge-E, 6 Cores, 12 Threads, 3.5 GHz, 130 W

I was thinking of the V3 series...

EDIT2: Nope, even the 1650V3 is unlocked...

You're kidding. I would have never thought that the 1650v2 was locked but the v3 was unlocked.

I got it wrong. They're both unlocked. For the system you're working on, it's down to the BIOS settings. Disable everything power management related except turbo boost and see if TS can work. You can even try disabling turbo, but that shouldn't be needed.

Post a screenshot of the ThrottleStop Turbo Ratio Limits window. It will show in there if the CPU is locked or not and if it supports overclocking.

The Xeon CPU-Z screenshot that was posted likely comes from a computer using a BIOS with the original microcode. Some CPUs are unlocked when using this microcode. Any BIOS updates removes that feature and locks the multiplier. I cannot tell by the screenshot what microcode version was being used.

 

[frankr2994]

I don't have the PC I'm helping someone thousands of miles away.

And I know I have a gen newer but overclocking is locked until a sleep resume cycle is done. I was hoping this had something similar.

 

[unclewebb]

That screenshot confirms that the E5-1650 v2 is a fully unlocked CPU. This is the same as any modern K series CPU with an unlocked maximum multiplier.

On your motherboard, the BIOS has locked out this feature. After you do a sleep resume cycle, does the lock icon in the Turbo Overclocking section disappear? Can you check the OC Overclock box if it becomes unlocked?

Sometimes the BIOS forgets to relock the CPU when resuming. That is a good thing when that happens.

Checking the MMIO Lock box In the TPL window can help unlock the maximum multiplier. This is only required on some motherboards. Some motherboards have the MMIO lock already taken care of.

Dell DCCU (Distributed Client Configuration Utility) has an option to allow previous BIOS versions to write. Some BIOS modders use this utility to install their modded files. But screwing around with the BIOS is always risky. Especially based on advice from me. So it depends on how risk averse this user is. On my antique stuff it's no big deal to brick something.
