Xeon L5639 Overclocking on X58

[K_Maru]

how you can ! how to lock ratio all core 19 or 20. My Mianboard Sabertooth X58

I took that picture while the PC was idle. I was just trying to show the other user that all of the cores do indeed hit 4.4Ghz. However, once more than two are cores are used the multiplier drops to x19 then x18. Which is indeed = ASS BACKWARDS. This is a low power CPU. I'm just running everything @ 4Ghz. x18

Edit:
I broke 12,100 in the WinRar benchmark

Imagine that.. 18 X 222 isn't 4Ghz. and you already said you're not stable at 223 which is barely 4Ghz..

Still waiting to see that cinebench Screen shot.
And it's not your board, you happened to get an exceptional chip.. Very lucky!

??? Dude I've had my PC running 4Ghz easily. I'm hoping you are being sarcastic right now. [?]. All I had to do was bump my BLCK and my PCI-E up 1 number. Also In my BIOS it says 3996Mhz [222] , but in Windows it says 3.974Ghz [jumps to 3.993Ghz] which I rounded to 4Ghz. Is that a problem or something? Also this is nothing new. I stated it here in my very first post on this forum:

Guess you forgot. Chill out.

Check out the specs.

Also the 4.4Ghz was here:

If you REALLY need proof of me running 4Ghz I can provide that easily. 4Ghz [x18]. I had pictures, but I had a hard drive crash. I've been running benchmarks all night @ 3.974Ghz and it will jump to 3.993Ghz. You want me to say "3.974Ghz" instead of 4Ghz or something?

Turn off speed step and the c states, that will allow you to disable the downclocking. Then boot back up to Windows and check if the cores are all at 4.4ghz using hwinfo.

Not saying you're wrong or anything, just trying to confirm if anything beyond x18 works on all cores. If so then 4ghz overclocks would only require 200 base clock and there would no longer be a motherboard limitation, but the IMC when it comes to overclocking.

 

[Burpo]

I'm using the exact same board (so are others here) but nobody has gotten past 215 bclk. He was lucky & got an exceptional chip. I'd like to know the batch number.

My SSD crashed at 214bclk, but was able to reboot at stock speeds & let Windows fix it. He's definitely pushing the envelope..

 

[aigomorla]

lol.. u have a messed up TDS...

either that or you left your window open and its snowing outside...
Look at your lows on your cores... 8C .... u cant tell me ur PC is running 8C on idle..

Wait what? If I turn off the C-states I'll lose the x19 and x20 multiplier. You need those in order to get the boost. Otherwise you'll be at x18 and go no higher. I noticed that when I checked HWinfo all of the cores were running @ 4.4Ghz. Then obviously they downclocked.

Well here are my temps right now . I snapped a picture. I usually keep it cool in here, but my PC does a great job of keeping the components cool. It could have been a issue with OCCT during the burn in-stability test I suppose. Temps still look good. Even with a high Vcore. My Vcore should be lower. It was 1.37V when I took this picture. I should be able to run this rig stable with only 1.32Vcore at 4Ghz I suppose.

I get some animosity from every post you make. Is there a issue here? Exceptional chip or not. I'm still having fun overclocking this beast. X58 isn't as easy as some of the newer platforms. It's a nice challenge.

I have no reason to lie . I actually did better. Got 10.36 pts

Here is the proof. Happy now? I'm satisfied with this chip. I no longer have my upgrade itch. The only think I want now is a 7990 or something.

Edit with updated benchmarks:

Cinebench 11.5 = 10.36 pts @ 4010.3Mhz [4Ghz]

Cinebench R15 = 938 cb @ 4010.3Mhz [4Ghz]

I'm hoping to break the 1000cb mark soon.

WinRar 4.20 = 12,148 @ @ 3.974.6Ghz [OR 4Ghz]

 

[Burpo]

I see a cinebench screen that says. 3.57Ghz. (16 x 222.9 = 3.566)
That's the point I'm making. Speedstep will never allow 4Ghz in cinebench.
No animosity.. you have a really good chip.. but to say you have it locked at 4Ghz is incorrect.

Alright. As far as I can tell. I have the cores locked @ x18. BIOS shows 4Ghz, Real Temp, HWinfo, CPU-Z shows 4Ghz. Cinebench reads what Windows tell it. I trust CPU-Z and other CPU monitoring programs than Cinebench so I'm not sure why you would. I don't think I'll be getting these scores @ x16 multiplier.

 

[Burpo]

You can turn speedstep off, but you can not change the way this chip works. Even with it so called "locked" at 18, it will drop as low as 12X. You can't lock the multiplier in with this chip. Run hardware info and watch it bounce from 12 to 18.. even when "locked" at 18.

 

[K_Maru]

Alright. Let's see if the chip will "bounce" The only time I've seen the chip bounce is when I have the C-states on. No C-State+Manual x18 set....from what I've seen locks the cores. I'll run a benchmark while using OCCT as the source since my words aren't good enough. Got work in the morning. I have to go to bed soon, but I'll try to run it really quick. Also explain to me how this chip works, because it seems like it's one thing after the other with you.

 

[Burpo]

Current HWinfo screen shot with C states disabled, speedstep disabled and multiplier set at 18X.. I don't push mine real hard..

You can't change the way Intel designed this chip.. HWinfo & CPU-Z monitor the CPU. Cinebench puts a load on & tests the CPU.. BIG difference..

 

[K_Maru]

Ok ran the benchmarks. OCCT shows the cores never dropping below what CPU-Z says. If you are trying to find something to complain about next....good luck. I have all of the cores locked at the speed I have set. Not 2 of them [x20]. I'm guessing your NEXT complaint will be the "Idle clocks". Smh. When I want to run 4Ghz I run all 6 cores @ 4Ghz [x18]. Now It's been fun. Goodnight. I'll be back tomorrow don't worry.

Edit after reading your last post:

Just read you post after I finished posting. LOL I was right. I already picked your next argument. You were going to speak about the "Idle" clocks. Good lord. I'm going to sleep. I don't have time to play games with you any longer. My cores are running @ 4Ghz or 4.4Ghz [x20 - 2 cores]. Deal with it. Let go of Cinebench. It's only reading what Windows tell it to read. Also that was sarcasm when I asked you how the chip works by the way. It's been fun.

 

[Burpo]

I'm not complaining, it's just the way the chip works. Cinebench uses the default multiplier of 16, even tho it tests at 18.
Good night

What makes you think he's got an exceptional chip? My motherboard refuses to post beyond 223 and it's rock solid at 222, but if I I boot up at 222 and overclock using software, I've gone as high as 230 before I gave up since there's no point if it wouldn't post at that ratio.

Seriously, download the overclocking software your motherboard comes with, you'll be surprised at how high your chip can go.


Also you CAN lock the multiplier to x18 if you disable speed step, c state, and enable turbo mode. It won't be a perfect x18 but it'll be close. x17.99996, x17.99994, etc.

Wait what? If I turn off the C-states I'll lose the x19 and x20 multiplier. You need those in order to get the boost. Otherwise you'll be at x18 and go no higher. I noticed that when I checked HWinfo all of the cores were running @ 4.4Ghz. Then obviously they downclocked.

Turbo boost (which enables 19 and 20) works on my EVGA motherboard with the c states disabled. Motherboard differences I guess.

But until we get can get a solid screenshot of all cores utilizing the x20 multi, turbo will still only work on one or two cores. From what I see in the thread you're the only person that claims it works on all cores. If it actually does, congratulations, we're all green with envy. Some people couldn't get pass 3.6ghz!

 

[Burpo]

Thanks for the info & will try that, but I'd still like to know the batch numbers of the chips you guys have. This one's been on 3 different boards, max's out same on all 3..

 

[john3850]

Cpu-z seemed to always show the the highest incorrect multiplier on x58 chips.
A program called Cpu Tweaker will give you the real multiplier just like HWinfo does.

Don't know mine since I lapped it off. Kind of moot anyways since we have no control over it and sellers are unlikely to pick out chips for you.

I'll have two extra motherboards by Friday. I'll see if they hit the same clock wall. Hopefully nothing less. The only reason why I'm incapable of going beyond 222 is because the sata controller won't post and detect anything beyond that. So it's an actual chipset limitation/motherboard as far as I'm concerned.

Alright let me explain this again. I know that highest turbo multiplier [x20] works on only 1-2 cores then drops to x19 and so on. I posted that picture because you said in your post that only 2 cores can hit the Turbo frequencies. From what I've seen ALL of the cores hit the highest Turbo Multiplier [x20], however they all drop at some point except two of them. When Idle they all usually drop to 2.6Ghz or something like that.

Manually set x12, x16, x18 etc. works for all of the cores. Now x20 [1 or 2cores] and x19 [3 or 4 cores] are limited. When 5 or more cores are used [x18] is next. The multiplier automatically drops obviously. If the chip gets to hot it will drop to x16 I bet.

 

[dragantoe]

I had this chip running 4 ghz (220x18) from August to late October, but I've decided to lower it to 215x18 because after a few days of it constantly being on it would bsod, also temps used to stay at around 55C on each core during full load prime95, and so I wanted to show how much of a difference it made to lower the clocks slightly

[/IMG]

this is prime95 blend test after 30 minutes. In game difference is non-existent, but it doesn't bsod anymore, and temps have obviously dropped significantly (probably due to vcore being lower)
I'm using a thermaltake water2.0 Pro with a couple corsair sp120s inside of a CM HAF XB (this is such an amazing case)

What are your voltage settings? vcore, vtt, ioh, dram?

WinRar 4.20 = 12,148 @ @ 3.974.6Ghz [OR 4Ghz]

You are going to need to hit like 4.5+ ghz to break 1000 cb and on gulftown that will require water or better if your not looking for a quick benchmark run and want 24/7 overclock at those speeds.

now that I think about it with the 210-222 blk limit on most x58's board and lower multiplier on these xeons it may be impossible to get your clock speed up that high.

may be easier on a 980x cause of the open multipliers!

The only way you hit 20x on an L5639 is if the C state is active that powers down all but two cores.

Windows does not accommodate changes in the number of cores while up, so you always "see" 6 cores, but the other 4 are soft off.

So you might see 20x on 6 cores depending on how your program gets and displays data, but those cores aren't on. The second you push instructions at them, the multiplier will drop.

I guess in that case I won't be going over 1000 cb. Never hurts to try though. I've gotten my BLCK up to about 226-227. It required some crazy ass settings though. I fear that the requirements could possible ruin other components on the board so I'll stick around the 222-225 area. I would love a 980x, but the price is usually to much for a old platform like the X58. Don't get me wrong it is a nice CPU. I can't find a affordable 980X-990X to save my life. I'd rather put that money towards graphic cards anyways.

This I know. I really hate how the CPU drops to x18 though. That's pretty much the reason I normally run at x18 multiplier. It's going to drop anyways so why not.
