Had a similar issue about a week ago.

 

If your motherboard or case has a reset button, shut down your system, spam the reset button 5 or 6 times, then turn on your system.

Tried it dident work sadly

After some tweaking i got my i7 960 to 4ghz at 1.32v stable

That is a nice start. But if your cooling can handle it, you can safely push is further if you want to. You can push vcore up to 1.375 volts (1.4 volts is max according to intel for long life span). Up to 1.375 is the voltage the cpu is dsigned to operate with in. You shut keep max core temp at 75 degress celsius for every day use at max load.

 

See "VID Voltage Range" longer down in the link. For normal operation voltage.

I had a I7 920 i pushed to 4.4 GHz at 1.43 volts at the end of the time i had it.

 

Now i have a I7 980X at 4.4 GHz at 1.41 volts and my CPU is not the best overclockable cpu of X58 chips. I stopped oc my CPU higher than this as i reached my max core temp target of 75 degress celsius right about there as you can see in the image below.

 

my point is that if you have cooling that can handle more heat, you can safely go a bit higher on core voltage.

Thanks for that great comment my cpu reaches 71c using intel burner but never goes over 65 in normal use. So i may be able to push 4.1-4.2ghz. My cooler is a captain 240ex from deep cool. Imma do an oc challenge with a friend this friday and record it. Ill post the vid when i make it.

Ah so you use an AIO. Im on air cooling and use a Noctua NH-D14 with 3 of noctua 3000 RPM industrial fans on it. Im not so fond of having water inside my pc that can leak out and roast it.

 

If your CPU is only hitting 65 C full load at normal use. That means all 4 cores running 100 % load, then you can safely go higher. As i told 75 C core temp at max load in normal use is where you shut stop going higher.

 

This is my pc with some ghetto mod, but it works great.

 

Well if you really whant record fun on X58, then you shut consider getting a 6 core CPU for X58, they are way more fun to mess around with than there older quad counter parts. The Xeon version like X5650, X5660 are can be found dead cheap on places like ebay. You can take the words from one that replaced a I7 920 with a i7 980X. gaming performance also increased a bit and the 6 core 32 NM chips also runs a bit cooler than the 4 core 45 NM chips as your´s is.

 

To give and idea of that. This is what i have achieved on my I7 980X on aircooling, but with high volts and temperature. Off cause these clocks are benchmark only.

 

 

For comparison between I7 920 and I7 980X.

 

Cinebench R15. I7 920 at 4.3 GHz vs. i7 980X at 4.4 GHz

Steam VR test. note that this test does not support SLI, so only one of the GTX 970 i ran together with my I7 920 whas in use in the test and the CPU whas only clock to 4 GHz as at that time the cooler i used whas not the Noctua NH-D14 but a single tower air cooler. While the I7 980X runs 4.4 GHz and a single GTX 1080 TI. The score for the I7 920 system would had been better if the second card cut be used as well.

 

The point with the VR test is also more to show that with a high clock 6 core X58 CPU, you can pair it with a pretty desent GPU to great enjoy in games that you may like to get on ultra og high settings with out losing FPS.

Vid is not a way to judge maximum safe operating voltage. Seeing that I’ve yet to see any degraded 45nm chips, I doubt even 1.45V-1.5V Vcore are particularly unsafe for them if cooled properly (water or strong air, though some chips aren’t even coolable at 1.4V). 

 

My W3520 can saturate a strong waterloop even running single core loads at 1.33V 

CPU is only running low 60s after a single run, but the water heats up incredibly quickly despite massive radiator space. No way of cooling this cpu at those clocks despite the super low voltage for the clocks. Sadly only scales to ~5.55GHz at 1.55V on Liquid nitrogen but still decent.

If the chip is not colable on 1.4 volts. I will say its more about a bad heatspreader or bad conection between heatspreader and cpu die. Those two chips i have/had where defently very coolable even on air at high clocks with all core and HT still on.

 

I am wundering why you are only running single channel memory on that screenshot. That will significantly hold X58 back in task that are memory depending as X58 is triple channel.

 

But according to Intel maximum voltage for these chips are 1.4 volts and i will never run my own CPU at 1.5 volts for every day use. As they gets to hot and watt use is very high and i would say those voltage will degrade the cpu faster over longer time.

Yeah, IIRC around 1.4v and 4.2-4.4GHz is the usual max for a daily rig to make sure you don't degrade the CPU, should be able to do 4.2 at a much lower voltage. I have a separate main rig though, so I just push the clocks as high as I can with my thermal headroom.

Its not running particularly hot its dumping a ton of heat in my loop. I’m using a strong fountain pump, a 280x140x30mm rad + 540x180x45mm rad with a decent number of fans and the water heats up quickly (7°C in 25-ish minutes). Not bad heat transfer, just stupid amount of heat dumped, significantly more then any other chip I’ve had for this socket (over 100 at this point). 

I was just testing the core, so no need to run triple channel. Triple channel with tight timings is no big deal for this chip even at higher uncore. 

No need to test everything at the same time on ambient. Uncore on cold goes to ~5.4 Ghz quite easily, ram to 2100 6-7-5 ish.

yeah around 1.4 volts that is as high you shut go on these chips. How much voltage you need to the cores also depends on how high you set uncore to. As you increase uncore you may also need to increase vcore to keep it stable.

Then you must have been very very unlucky with that chip. Its not normal a CPU needs this cooling according to the volts you throw at it.

 

Off cause it also depends what load you throw at it. Exsample when i stress test my cpu with intel burn test on very high setting. The cpu gets up to 20 degress celsius hotter than normal max load. Intel burn test use Lindata or linpack its better known as with is very hard on older CPU´s. lindata is also used in exsample OCCT stress program for cpu.

Its one of the best known 45nm CPUs for 1366, its just hard to cool at 4.8 Ghz on ambient. 4.5 GHz at 1.2V are easy to cool lol

Ah i see. 4.8 GHz is high clock.

 

For the fun of it i ran super pi on my own system. First with CPU fan´s locked to 1200 RPM and case fans at 900 RPM and then back after that all fans at there max speed. that is around 2900 RPM for CPU fans and 2300-2400 RPM for case fans that is corsair ML120 so you can se temp difference on air cooling. I keep alle cores and HT on. I ran it just on my every day settings. so no optimisazing for super pi run.

 

ups on second image i forgot to chose different fan in CPU-z, but shut not mater so much as its the same settings. only fan speed is changed.

Is it only for X58? I want to ask about P/H55.

Mostly X58/X99, some X79/X299. So mainly X series chipsets, IDK much about P/H ones but other peeps might.

OK I find Asus P6T-SE pretty cheap for around 30usd is it a good mobo? I want to pair it with X56xx. There's some problems nvm

That's X58, lol. 

 

IIRC the ASUS ones are usually decent, but there's a heck ton of P6 series ones and I forget which are the good models. I've mostly ran ASUS Rampage and EVGA boards.

Well I found it not too long ago, after all I would prefer X56xx more rather than X34xx

[Oalei]

Is all P6 compatible with X56xx? I mean for that specific model

I don't know if they kept that series through other sockets, like they've kept the Rampage and Crosshair lines for quite a while. Usually if it's socket LGA1366 and boasts of overclocking, it's X58 (only exception I know if is the SR-2, it's 5520). Be aware some V1.0 boards don't support Westmere-EP (the X56xx series CPUs are westmere-EP). 

[Ground]

P6T SE is decent for daily overclocked. For benching you can most likely forget about it if you care about that.

Has anyone's system properly booted into Windows (I don't care if it runs Cinebench or not) with an X5675 (or something similar) at 5GHz?

 

If so, what was the core voltage, the BCLK, and the multiplier?

 

Why am I asking? I want a fancy CPU-Z validation.

https://valid.x86.fr/uzqkyj was mine, it must have been at least 1.45v because I'm running 1.41v now just to be stable at 4.6ghz. Just make sure your uncore multi is low enough that you can keep the QPI/VTT voltage in check but I doubt you'll hurt it from pushing it a little for some validation.

Correct me if I'm wrong, but last I checked this:

is not equal to 5000.00Mhz.

My base clock is often upto half a mhz off to the point that it cinebenches lower until I wait a few days and restart it a few times.. If I mess with the PLL, I think it will drop to like 199.1 too. I've tried all sorts of things. It's just however the hardware feels at the moment on what it's going to do that day lol.

 

Now that it's stable I've stopped messing with it since performance only seems to go down the more I mess with it. Today though, it's doing alright.

I know people have pushed these chips to 5GHz, but IDK what settings they were using and such. Once I eventually have the time/energy I wanna yeet a horrendus amount of voltage at my various chips and see if I can get any of them to run that. My current X5670 does 4.56Ghz at 1.45v, CB20 stable, can do CB15 at 4.74Ghz on the same voltage.

I can confirm that 5 GHz is possible on X58 chips, but it really need some good cooling and at times dangerous high voltage. So unless you are prepare to risk roast your cpu, i will not reccomend it.

 

But one of my friend had a I7 980X that cut do 5 GHz. But on a custom water loop with a waterchiller. I dont know what voltage he used and he can properly not remember today.

 

My own I7 980X i have gotten up to 4.75 GHz at 1.55 volts. Its not the best cpu i got, but i manage to do it on air cooling on a pretty chilly night.
