1366 x58 Xeon Enthusiast overclocks club

I have seen many people running just under 1.5v but i think intel spec sheet is on the page first page
 
I'm still running at 4.0Ghz and turbo to 4.4Ghz @1.30v and it has been over a month.. just gaming with it and not trying to kill it with Intel burn test.
 
I do know the intel spec for this cpu, 1.35, still... from an intel point of view it would be wise to make a very very conservative approach to the cpu voltage subject (commercially, because they do need people to replace the cpu's asap, technically it is obvious there must be limits, higher voltages do have consequences).

I was anchoring my thoughts purely on a temperature logic "if it's cold, you can put more voltage to it", and right now my cpu is operating at temperatures that fall within stock range (I've got a dual X5670 setup and under load they operate within the same temperature range).

I'll be following your advice and keep it as it is for now, as soon as I find the time I'll try Ocre's approach, it makes much more sense than mine. Don't want to degrade anything... besides... this already is a fast computer, I do believe it will endure few years.

Thank you all
 
This thread is mainly full of people with the modest and fully stable overclock.

But there are many people pushing these chips on up there, close to 5ghz. They use voltages well past intel spec sheet.
http://www.overclock.net/t/1489955/official-x58-xeon-club#

I have many posts in that thread. The high voltage is to hit 5ghz and take a benchmark/snapshot he even calls them "suicide runs"...
That is not for 24/7. Read every post in that thread and the OP even says that.
Another thread he started
http://www.overclock.net/t/1461359/...w-discussion-and-xeon-l5639-benchmarks-inside


People can try that high a voltage loaded 24/7 and see what happens. Let us know how it goes.

Westmere-EP & X58 Overclock Info
CPU Max Voltage & Power Guideline Misconception

Alright we will address the most common misconception I’ve seen across the web. Time and time again X58 users will point to a commonly used example provided by Intel, stating that the max voltage for Westmere-EP is 1.4v. Meaning that as long as you set the CPU voltage to 1.4 or below you processor will be fine. This is simply not true and users constantly misunderstand how the CPU actually performs and how Intel designed the CPU. So let’s get one thing correct 1.35v is recommended by Intel on their ARK pages. People spread 1.4v as the max incorrectly.

The reason 1.35v is the recommend voltage is because Intel said it is. Also one thing that is normally overlooked is the voltage spike. Voltage spikes can literally kill the CPU and\or the Motherboard + MB components. This is more prevalent by setting manual or dynamic vCore too high. Intel also included a feature that will hopefully prevent the CPU from frying [old tech]. If the CPU temperature is too high the processor will cause the PC to freeze or BSOD. Otherwise continued use at high temps will cause the CPU will degrade. Vdroop also helps preserve the CPU life. vDroop will allow the CPU to operate under load at a lower voltage while preventing or avoiding spikes that will surpass the voltage set[not manual] in the BIOS. If you have LLC [Load-Line Calibration] set to AUTO[depends on settings] or Enabled then vDroop is DISABLED. AUTO can vary so either use Enable or Disable. This means that you could unknowingly damage your CPU over time. Some motherboards handle LLC better or worse than others.

Anyone running 48GB here? I'm currently running 24GB, and was hoping to max out the board. Just wanted to see if people were able to do that and still have relatively successful overclocks
 
Any gotchas with the Asrock x58 Extreme? I'm considering buying a refurb for an ESXi lab box and wondering if there will be any problems recognizing the Xeon. I won't have a consumer proc to do a bios upgrade. Also wondering if it will unofficially support more than 24 GB of ram.

Thanks,
Chris
 
There is really nothing between the CPUs integrated memory controller and the ram so in theory you should be able to use more than 24gb ram. My board list only up to 16gb but I have seen people running 24gb. I heard the 16gb listed was just because there was only 4gb sticks available at the time. So, 4gb times the 4 memory slots and you come up with 16gb. Boards with 6 memory slots had 24gb listed.

I have seen people run over 24gb on x58 boards. Supposedly, its possible but you may need extra vtt to run it.
 
Got my P6T Deluxe V2 up and running. It came with an i7 920. Seems to be working well so far.

One thing I am missing is the voltage offset that I've gotten so used to on Gigabyte boards.

I'm not seeing anything similar on this board, it'd be kind of a bummer if it runs at full voltage all the time when overclocked.

Check the first page.

48GB runs just fine, didn't seem to have any negative effect on the overclock. In saying that though, I dropped back to 24GB, 48GB is way overkill, I could never even get close to using even half.

C states and speed step will give same results using less power

Thanks. I've got some more RAM on order and hopefully no issues. I run a lot of nested vmware environments and I'm hitting the limit at 24gb. One of the attractions of Haswell E was 8 dimm slots, but with the price of DDR4 I'm not touching that for a while yet.

Yeah, I have all that enabled. I'm actually running at stock volts right now on the 920 @ 4ghz (1.25v) so the volts are dropping as expected (in CPU-Z, etc), but It'd be nice to have that option while setting the voltage manually as well.

Anyone crossflash a bios with offset voltage adjustments (like the P6T WS PRO or P6X58D Premium) with the Deluxe V2? I was reading they work pretty well on V1.

The crossflash you've mentioned will work on the V2 as well, since both boards are nearly identical, however, the P6T WS PRO BIOS does not support offset voltage adjustments, either. As for the P6X58D Premium, it does support the offset voltage and its BIOS can be crossflashed on the V1/V2, which I've tried myself. The drawback of going this route is that you lose some functioning USB ports (4 I think) and the ability to lock in turbo multis under load as opposed to the P6T WS PRO.

Ahh, that's too bad, I don't think I'd miss the usb ports though.

I'm actually pretty surprised, 200 blck is stable on this board at 1.25v qpi, although I haven't had any luck getting my ram much over ~2000mhz (currently in dual channel).. The IMC on this 920 seems pretty weak compared to the 860.

When you say lock in the turbo multis, you mean with all cores loaded? So a 920 for example could use up to 22x? That'd make the x5650 more palatable.

Yes, after crossflashing your V2 with the P6T WS PRO BIOS and enabling the "High TDP Turbo Mode" you will be able to run your i7 920 at 21x, which is the top multiplier across all cores, without throttling under a heavy workload. Also, If you want to take advantage of 22x in single-threaded applications, make sure you have C-States enabled in BIOS, otherwise it will always stick to 21x. If you're interested in crossflashing, a few weeks ago I linked this article.

This vdroop has been debated back and forth. Really not sure how much it matters to people running 1.35v and under. I read the anand article a couple yrs back but there was a high tech rebuttal from another site....,
Don't have the time to look it up and I don't remember off the top of my head. I will look it up if I get a chance, I believe it was done with an O-scope.

Anyway, I ran for years with LLC on with no issues. The 920 was always about the same as it ever was. It then again, my daily overclock was only 3.8ghz.

I really don't think it matter at all for anyone getting a westmereEP today. It seems the market is continuing to be flooded with these server chips. My expectation is that the prices will come down down and down. There are only so many people willing to invest in their old platforms and there is absolutely no shortage in westmereEP CPUs right noe. My expectation is that the CPUs will continue to flood the market and the motherboards will become more rare.

But this post made me take action regardless...
I disable LLC and my overclock failed. I need extra voltage. My dynamic voltge offset had to be set up higher, something like .02 or whatever 2 notches up is. Anyway, when stressing I see my CPU voltage goin up and down 1.264 to 1.28 for all cores at 4.2ghz.

Passed ibt max but haven't ran it long enough to see how we'll stable it is.

Idk, my testing showed stable at 1.28v when at 4.2ghz all cores and threads. The 1.26 dips are a little scary. Already though I see the voltage jump up higher o. Single thread stuff. Higher according t my app measurements.

Not sure If I will keep running with vdroop but I am giving it a shot
 
Okay, here you go - SUCCESS! Glad I didn't just give up on that first bad CPU...

x5670stock_zpsc6b69885.jpg


Running it at stock settings for tonight to give the AS5 some burn in and to get me some sleep. Tomorrow night I'll load my BIOS 3.8GHz settings for my i7-950 to start and fire up some Primegrid... But tonight I'll let it run 12 threads of BOINC for the [H]ard Commandos. :D

You know, I've been overclocking so long, I can't remember the last time I saw a CPU under full load running 37*-42*... That's usually my idle temps!

Don't do it like that.

Your new CPU is 32nm, your i7 950 is a 40nn chip. They have different voltages and completely different sweet spot.

The 40nm chips had a sweet spot around 3.8ghz on average. Sure, there were many that could go higher butt it took more and more effort.

Your new chip, westmereEP. Most of them have a sweet spot of 4.2 or slightly over. They can hit these speeds at veey reasonable voltages and temps. Sure, a lot of people can go higher, but it just gets harder and harder to stabilize.

I have an x5670 and I will give you a starting point if you want to try. Not sure if your board will let you use your turbo multiplier 24 like mine, but try this.

Blck 175
Vcore 1.32
Vtt 1.22

Put your memory multiplier wherever to keep memory around its stock speeds for now
and the uncore multiplier aim for 3000-3300mhz.

That should roughly get you at 4.2ghz if your board allows you use of the turbo multiplier.that is 6cores and 12 threads at 4.2ghz..,
After you check stability, you may end up changing the voltages. But that should get you really really close to dialed in. My CPU works 100% stable with slightly less vcore. The vtt is just bumped up slightly for extra stability, as a habit. 1.22 isn't slightly over stock but you may not even need it.

I also have my turbo on and all my power savings on in the motherboard. So my chip turbos to 4.4ghz single thread and 4.2 ghz for all core loads.
 
Thanks for the tips - I'll keep that in mind, but the reason I was going to start with my 3.8 settings is that they are almost identical to your recommendation! For 3.8, I've been using 181 bclk x 21 @ 1.34 vcore, and for 4.0, I just bump bclk up to 191 and vcore up to 1.36. I know I shouldn't need 1.36 to hit 4.0 with the chip, but finding the lowest stable voltage is just part of the process. And my memory is stock at 800 MHz @1.65V anyways, so 200 x 21 would give me 4.2, and 200 x 22 would give me 4.4, both without raising blck above my stock memory speeds. Honestly, if I can get a rock stable 4.4 or even 4.5, that's as far as I'd push it no matter what, but I'll be happy with 4.2...

Just FYI, in my case power savings doesn't matter at all - this computer runs BOINC 24/7, so power savings would never have a chance to kick in. Finding the lowest stable voltage is far more important for my rigs! :D

And I agree, I too always bump up Vtt a bit for safety! So now that you see my full plan, any more thoughts?
 
Wondering something about the x56xx.. Is the uncore multi locked, and does the uncore require 2x the memory speed like the 920?

I found out the reason that I was able to get my ram stable at 2400mhz on my 860 is the uncore only requires 1.5x the memory speed (3600mhz), while the 920 requires the uncore to be 2x the memory speed..That would be 4800mhz uncore, which is probably impossible without some extreme voltages. I'm only able to get ~3800mhz uncore stable at any ram speed with the 920 (1.35v qpi/vtt).

I've highlighted all the parts I heavily agree with.

I'm also running an x5670 with the same config. One thing is that my chip starts to become unstable over 175 BCLK /w turbo and I can't really figure it out.

One thing is for sure , a Westmere hexcore @ around 4ish GHZ is a beast.

I'll echo the fact that the difference between my i7 950 and this x5670 is night and day
 
Is VTT what Asus calls "QPI/DRAM voltage"? If so, mine needs to be much higher than that to go above BLCK = 191 MHz. I tried 1.33 V and can only get up to 200 MHz ish (210 MHz isn't stable).
 
Wondering something about the x56xx.. Is the uncore multi locked, and does the uncore require 2x the memory speed like the 920?

I found out the reason that I was able to get my ram stable at 2400mhz on my 860 is the uncore only requires 1.5x the memory speed (3600mhz), while the 920 requires the uncore to be 2x the memory speed..That would be 4800mhz uncore, which is probably impossible without some extreme voltages. I'm only able to get ~3800mhz uncore stable at any ram speed with the 920 (1.35v qpi/vtt).

No

The westmereEP has a 1.5x minimum. Uncore multiplier can be as low as 1.5x the ram multiplier. So you should be good

What do I mean?

Turbo is interesting on the x5670. Although my board lets me use the 23-24 multipliers, they are technically turbo multipliers. Actually, there are many boards that let you use 24x on the x5670, 24x for all cores full load and never throttles. But there are a few that actually throttles down when all cores are fully loaded, they will throttle down to 22x. This is because, technically even 24x is a turbo core.

Seems most boards are happy to allow 24x with all cores fully loaded which then its acting like its not a turbo multiplier. When I overclock with turbo on, my board boost up to use the 25x multiplier for light loads or full single core loads. Actually, if I have anything monitoring my CPU speeds in daily task, like letting my kids loose on it, the CPU mostly sits with a 12x multiplier boosting to 18x and the 25x. It usually bounces up and down these states back and forth as they do what they do all day long. Depending on the task. Most of the games my son plays have my CPU running at 25x turbo.
But the games I play are much more CPU demanding and there is heavy load across several cores. This has my CPU locked at 24x multiplier, running at 4200mhz..

So my turbo with this ud3r board is just my 25x multiplier. Any full load or heavy load across multiple cores makes my CPU lock at 24x.

I have stabilized 4.4ghz and 4.6ghz all cores. But things aren't nearly as easy or smooth sailing. I merely stabilized them when I was tested my boundaries. Both 4.4 and 4.6 were tricky in the fact that I turbo and power savings features would cause crashes. I didn't spend a lot of time on it so I am not saying they were impossible. Just totally different from running my milder blck 175 overclock. I could just turn on all those features with ease. But at 185, its not nearly as friendly. The higher the blck, the more I would suggest constant voltage and speeds. The stability can be 100% but allowing dynamic voltage or turbo 25x core caused crashes.

I am sure I can tweak it out but my chip really seems to be very happy at its current settings. For my CPU, its a mild and solid overclock that is more like a stock chip. Like a stock 4.2ghz westmereEP. 4.4ghz and I am running more liked an overclocked scenario. It's not bad but not nearly as elegant
 
Congrats! I think x5670 is really the sweet spot right now price/performance wise. x5675 and up starts getting super expensive for the gains they bring

Yeah, the 5670 seemed the the best for me, although I'm not sure how the F batches are.. I guess I'll find out. :)

I've been having some fun with this board, both my w3520 $10 "test" cpu and the 920 that came with the board do 200x20 stable at 1.25v on both qpi and vcore (ram at 1600mhz).
The 920 needs a lot of volts to get much past that, but the w3520 will do 4.4ghz at 1.4v which isn't too bad, but my cooling can't keep up.

I can get this board up to 220 bclk without issues at 1.3v qpi on both the 920 and w3520.. Coming from my P55A-UD4P, that seems pretty good as that'd max out around 210 or so.
 
Vtt 1.22

Put your memory multiplier wherever to keep memory around its stock speeds for now
and the uncore multiplier aim for 3000-3300mhz.
I've highlighted all the parts I heavily agree with.
So is there a reason 3000-3300 is recommended? Leaving the uncore on auto in my BIOS has it at about 3380 when I'm at 4.0 GHz (191x21) - too high?

And just as an FYI, these P6T Boards are a bit lacking in multipliers when it comes to setting memory. After I set the blck, I typically only have one or two settings that are actually usable... :rolleyes:

Is VTT what Asus calls "QPI/DRAM voltage"? If so, mine needs to be much higher than that to go above BLCK = 191 MHz. I tried 1.33 V and can only get up to 200 MHz ish (210 MHz isn't stable).

When I set my memory to use the X.M.S. setting in the BIOS, it automatically raises the QPI/DRAM setting to 1.35V. That ran my current memory rock stable at 200 blck for over a year now... So you're not alone going that high!

From what I understand both the board and the CPU play a part in how high the BCLK and UCLK clock will go. I believe the QPI/DRAM voltage directly affects the BCLK, UCLK/Uncore, and QPI frequency stability and limits.

From what I've seen ~3500mhz UCLK should be stable at 1.3v-1.35v QPI for most systems.. Once you start getting in the 4000mhz+ range, it usually needs a lot more QPI voltage (again, this depends on the board/cpu). I don't know enough about how Westmere reacts to all of these settings, but I'll find out next week.

I'm not sure if I'm correct on everything as I'm new to x58, so feel free to correct me if I'm confused about something. ;)

Edit: I do have a quick question. With your x5670 and P6T Deluxe, if you set the BCLK to 200 and set the ram to 2400mhz, what is the lowest UCLK frequency you can select? Thanks :)

It will be 3600MHz on ULCK. All you have to do in order to figure out the lowest UCLK is add 50% (the ratio of 1.5x) of speed on the current RAM frequency, like the following:

1600MHz (effective) RAM -> 2400MHz UCLK
2000MHz (effective) RAM -> 3000MHz UCLK
2400MHz (effective) RAM -> 3600MHz UCLK
 
Quick update guys:

I got 180BCLK with turbo and all power saving etc etc... so 4340mhz all core turbo, and like 4.5ghz single core on my x5670 ,

but i needed about 1.42vcore , and i needed to bump VTT (in my case aka QPI/DRAM) to 1.35V

either way I don't like how much the temps rose for 140mhz boost , and i don't like how I had to bump vcore from 1.35 for a stable 4.2ghz turbo , to 1.42V for 4.3ghz /w turbo

i'm still debating whether these settings are DailyDriver worthy

I know that, but I read that some boards that don't have the microcode update can't go lower than 2x.

in my bios it says it cant...i actually go a little above 2x just for the performance increase but i don't use speed step or turbo either...just all c states enabled which more or less does same thing without the extra latency from speed step
