Throttlestop overclocking Desktop PCs

[Retrorockit]

It took 1.4375V. to get 4.15GHz. I see 266fsb also. I would have VID to 1.45V. and let TS undervolt it back down. Then you'd know what that MB is made of.

I see you've had that chip to 4.5GHz @ 1.5V on an ASUS. Was that on air or water?

No TR, just tinfoil (it changes CPU VID from 1,2875V to 1,3875V).
ASRock board supports BIOS multiplier change, no Vcore change support.

Air (Thermalright Ultra 120 Extreme + AC MX-2 paste + Delta FFB1212EHE @ 7V).
But game stable was ~4,28GHz @1,525V (no LCC)

 

[Retrorockit]

The Dells don't have VID in BIOS. TS works great for VID with an unlocked CPU. Seems like you missed an opportunity to try it.

The Dells don't have VID in BIOS

There is no need for "having" VID in BIOS.
VID is Voltage Identification.
Basicly, it's default voltage every motherboard must use when they initialise a CPU.
DELL/HP PCs must obey VID as well, because that's what tells MB what Vcore to set.
VID Mod I used for my 4CoreDual board, forcefully changed VID of my processor (on hardware level). So, regardless of BIOS locks, and regardless of what was set in factory by Intel, voltage set by motherboard will be adjusted accordingly (if VID mod works correctly).
Because of ^that, VID mod will work on Dells as well (or any LGA 775 MB you can buy).

 

[Retrorockit]

I understand what a VID Pinmod is. Throttlestop can do this in Windows and save the setting with Core2extreme CPU. I wonder how TS would respond to a VID hardmod. Would it allow decreased voltage from there? would it allow further increase, or would the hardmod lock the setting? If you had tried TS you should have had any Voltage you wanted, and any multiplier also.

Good news
http://valid.x86.fr/6a4a9i
It works on my ASRock 4CoreDual-SATA2 R2.0 (no VID/BSEL mods).

I found a bug (at least with my MB) :
Multipliers above x15 don't have "x.5" (that's in BIOS), and when x15.5 or any other x.5 multi is set in Throttlestop, it doesn't work (multi is getting rounded down to closest lower "full" multiplier).
Also, I think this is the reason why CPU-z is broken when multi is over x15.
"Broken" as in it causes frequency error on valid result (bad frequency readout on otherwise valid result) :/
Can someone pass along this information to CPU-z programmers ?

 

[Retrorockit]

4Ghz @ 1.376V. That's nice. The 240FSB is a little strange. I never got past 15X266 with my old 65nm quad, and it was whole multipliers from the start.

 

[agent_x007]

4080MHz, but who's counting
Well, this board can't do much more over 266MHz to begin with (BIOS "ends" at 300).
With Quad Core installed, FSB is lowered by few percent because of stability (that's in CPU Support).
Next is RAM and it's inability to go 1:1 on default (MB thinks QX9770 is 800MHz CPU), without turning off two of it's 4 cores.
I lowered FSB to test how far you can go
Only 45nm CPUs have half multipliers, and that ends with x15 multi.

 

[Retrorockit]

I saw documentation that the X38 chipset (hidden 400 FSB support) has memory straps that only allow 800mhz memory speed with 400fsb even though they support 1066DDR22 @ 333fsb.
So it may be an Intel chipset thing. Maybe the CPUID is locking that in.
But I guess that's not it since you aren't running 400FSB.

 

[agent_x007]

ASRock I'm using has VIA chipset NOT Intel one (PT880 Pro/Ultra).
Don't confuse Real Frequency with Effective Frequency.
400MHz Real = 800MHz effective for DDRX RAM (Because DDR is "Dual Data Rate").
200MHz Real = 800MHz effective for all FSB speeds (because FSB is "Quad Pumped Bus" or for CPU-z "Rated FSB" value = 4x "Bus Speed" value).

Regardless, to get 800MHz on RAM on LGA 775, you need 200MHz bus speed on FSB (it's minimum value for ALL Intel chipsets that support 800MHz DDR2 RAM).
Effective FSB frequency = max. effective DRAM frequency you can set.
So, with 1600MHz FSB, you can set 1600MHz on DDR2 RAM (if it existed ).
You can do that no problem on DDR3 based boards.

i have a question in options on throttlestop it says

do not reset FID / VID on exit and its checked by default i have a dell optiplex 745 and i have a qx6700 coming from ebay i read the quide it says to check the box but as i read it you say it should say reset FID / VID on restart so im confused

also do you think i could set the multiplier of this cpu to 11 from 10 without increasing the voltage because i think 130 tdp is the max this board officially supports and i assume raising the volts would take that higher than 130

havent oveclocked in past so im pretty noob but nice work letting people know about this i though i was stuck with a q6600 or q6700 nice to know i can go up to a qx6800 at some point if i want

 

[unclewebb]

Some people use ThrottleStop to set the FID / VID and then they prefer to exit ThrottleStop. After they exit, if they want their FID / VID settings to persist, they definitely do not want ThrottleStop to reset the settings that they just made. Other users want the FID / VID settings to return to their default values when they exit ThrottleStop. If they play around with the program, having the settings return to default on exit is sort of a safety feature. Use this feature however you like. If you do not understand what a feature does, give it a try and see first hand what it does. Trial and error is the best way to learn ThrottleStop. Learn what each setting does. Run a second monitoring program like CPU-Z so you can see what happens to your FID and VID with various adjustments.

The TDP rating of a processor is a maximum rating based on an Intel specified load. There are some testing programs like Prime 95 that can put a CPU over the TDP rating even at default specs. This number is just a spec just as the TDP rating for your motherboard is also just a spec. It is impossible to know how close to this spec your CPU will actually run at. It depends on what software you run and it depends on if you have a great CPU or a not so great CPU. Some CPUs can happily run fast with very little voltage. Other ones might need a pile of voltage to be stable at default MHz. No one can answer these questions for you. Some hands on testing on your motherboard is needed.

You can definitely increase the multiplier to 11 but no one knows if you can do that at default voltage or not. There is no way to know unless you give it a try. If it needs more voltage to be stable, give it some more voltage. The world will not come to an end. Your motherboard probably won't blow up and these CPUs are built like tanks. A little extra voltage is like shooting a B-B gun at a tank.

My QX6800 G0 runs fine at 12x and stock voltage (1.337v) in my Dimension E520, but as mentioned above, it may depend on your luck as well.

 

[timduece]

cool thx for the replies very helpful

 

[Retrorockit]

The QX6700 are alll B3 stepping and need more Voltage per Multiplier than the SLACP QX6800s which are G0 stepping. This also means they're a bit hotter running also.
But Gateway sold computers with that CPU at 3.2GHz and full warranty. So I would start there. I wrote an article at Tomshardware "How to Overclock dell BTX Computers" based on an e520
For the 745 the D9729 cooler bolts in, but the T9303 is better. You need to move the holes in the top of the cover to use it. Stick some heatsinks on the VRM MOSFETs (there are only 6). I got 3.45GHz out of an Opti 745 with a B3 QX6800. So that should be a reasonable goal. I only spent about 1/2 hour on it because it didn't run like the E520 so I lost interest. But at CPUZ 3.45 is the typical overclock.

I just found a Dell Vostro 460 running an i5-2500K at userbenchmark.com Like many Dell users it wasn't overclocked. But it is an unlocked 95W CPU which makes it a candidate for TS overclocking on any Dells that can run it. 95W is a very common CPU limit on Dells.

[Retrorockit]

I also found an Optiplex 7040 running an i7-6700K 91W so there may be many more combinations out there to be tried.
http://www.userbenchmark.com/System/Dell-OptiPlex-7040/20989
I found this also. Dell T3500 workstation running W3690 @ 4GHz.

I don't know this user, so it may have been done some other way. But I don't know what other way that would be.

Hey guys!

I own a Dell T3500. I planned to build a cheap gaming PC with a Xeon x5650 and overclock him on an old workstation. So i bought a T3500 and a Xeon. I did know that the BIOS would lock overclock settings, but after trying with XTU, SetFSB and RW-Everything (direct programming to the clock generator on the mainboard) I could only change the clock about a few Mhz before it freezed.

I then tried Throttlestop and wasnt able to change anything. I have no "locked" or "unlocked" button some talking about and dont know where the hell I have to set the +1 for baseclock, because Im not able to open the BLCK Tab

I also have seen this:

I found this also. Dell T3500 workstation running W3690 @ 4GHz.
http://www.userbenchmark.com/UserRun/3125524

too, but Im wondering about many things. First of all, did he overclocked the processor only with the multiplicator to 4ghz? In the specifications you can also see that he uses 3x8gb of RAM??? On a Dell? In the datasheet they said a maximum of 4gb sticks is supported.

Can anyone help me? If needed I will post a screenshot.

Im using Win10, with the main parts of the T3500, a 750ti and 6gb RAM, (Im waiting for 12gb).

Have a nice day

EDIT: I have the solution how the Benchmark user overclocked his CPU: He did it with XTU, as you can see in some youtube videos.
EDITEDIT: If you want to go over 4ghz you can just bump up the first 2 Cores to get a stable result.

Throttlestop only overclocks unlocked CPUs. The confirmed unlocked LGA1366 CPUs are the i7-990X, The i7-980X, i7-975X, i7-965X and the W3680, and W3690 6 core Xeons.
The last 2- i7s were 4 core 45nm CPUs the others are 32nm 6 cores.
A question came up about 8GB RAM modules on X58 MB. here's an interesting thread on that.

I've contacted Crucial.com tech support with this and am awaiting they're reply.

Okay, that sounds good. Im selling now my old G3710 to buy the w3690 ;-)

Have a nice day

You could save about $50US by getting the W3680.
Here you can see the raised multipliers at CPUZ

Here is Crucials reply to the 48GB RAM in an X58 computer (6X8GB).

Thank you for contacting Crucial about your T3500. I've looked into this for you and according to the document you've provided, the 8GB modules should work in the system.

If you'd like to try to do this to get to 48GB, you may certainly do so, as we do have a 45 day money back return window for direct purchases. If you intend to do this, I'd recommend running a system scan from www.Crucial.com and contacting us back with a link to the results page, as this will help us try to find a matching part.

I think the advise for a scan of each system is a good idea since memory support varies from CPU to CPU in LGA 1366.

More on this. I found out that the X56xx xeons support 288GB RAM and there are reports of 16GB module being run on X58 with these. Hmmmmmmmmmmmmm.
So I don't know what this means in the real world.

Hey Retrorocket,

that sounds great!

Actually I could save 50$, but because I cant increase the CPU voltage on my board, im only able to overclock via the multiplicator. So a higher baseclock, will bring much higher results, you know? Or do you think I will be able to increase the voltage as well, because this CPU is unlocked now? I thought this would depend on the mainboard, not on the CPU

Have a nice evening

A lot of the chipset functions have been moved to the CPU core now. TS can raise Voltage on unlocked CPUs. Even on LGA 775 the Voltage can only be raised on unlocked CPUs. I've raised my Voltage to 1.588 on my QX6800 with TS. I would put the $50 towards a better GPU/ or PSU.

More good news, I found a couple of LGA1156 Unlocked CPUs under the 95W limit. i5-655K, and i7-875K
https://www.anandtech.com/show/3742/intels-core-i5655k-core-i7875k-overclocked-and-analysed-
The i5-655K overclocks better and is selling in the $60-$80 range.

[Retrorockit]

The i5 655K is a 2core 4 thread CPU. The i7 875K is 4 core 8 thread but won't run much beyond 4GHz.

 

[WillGIam]

Yes, but not on my mainboard Thats the problem. Otherwise the x5650 would be enough.
