Xeon L5639 Overclocking on X58

[Burpo]

My son now has that board.. SWEET Back the ram down to 1600s.. UClock & QPI set to auto, PLL set to 1.9 v

 

[jforce321]

thanks for the video burpo, but would the voltage of a new kit help since i found a gskill 4x3gb kit that is rated 1.5v instead of 1.65 so i wasnt sure if thatd give me more headway, and as for my ram i could probably sell off the old sticks to mitigate some of the cost.

is 4.2 the top for most of these chips since ive seen alot of people getting up towards 4.6-4.7 speeds.

 

[Burpo]

RAM isn't going to help, yours is fine @ 1.5v. PLL volts is important tho. Here's my 24x7 settings and I work this machine and have been for over a yr. 1.94 volts causes a shut down after awhile tho.. I give CPU a lil over 1/4 volt offset ( I have good cooling) and let it eat @ 4.4 Ghz..

i see, so why do you have a bit of an overclock on the pci express slot?

 

[Burpo]

Found out awhile back that it helps stability @200+.. Cinebench would error out (sometimes) right at the end.. until I bumped that up. You may not need it, mine does when I push it (212 & up), so I leave it there.

Thank you for the reply Burpo. I set uclock and qpi on auto but pll is too hot, leave it at 1.8v.

I want to use the 22-23 multi so i go the other way. Underclock the ram instead of overclock it. 22x182 seems to recquire 1.344v and not 1.36.
I go for it because i can run burning tests with case fans set on slow mode and stay under 80 degree Celsius. I have lowered all voltages on minimum. The bad point is that the ram is under 1600mhz at an average 1455mhz.
Without hyperthreading temps goes a lot down. Maybe i can try to increase the block and win some mhz on the ram and processor...to have a gaming configuration saved in the bios
Prime95 is still running 45 min without error at 22x182. A long time i haven't seen it. It seems that my ram was unstable at 1800mhz or maybe the qpi and uclck on auto...
4ghz on 12 cores with turbo and air cooled . I continue to test the stability but i want to thank you very, very much Burpo . I have read a lot of your post and decided to buy one x5650 from Germany for 89 euro with sending. It never happened if i haven't seen your posts. Thanks

 

[Burpo]

You're welcome! Glad you got it somewhat sorted out. The Hexcore Xeons are good value & do most work loads with ease

 

[pouki67]

Thanks. Sorry for bothering you but i have a problem. I reach 191x(22-23) without hyperthreading. I currently use 1.4v max and it seems stable but i encounter a problem with my gpu driver apparently. I have a AMD card R9 280x (HD7970 rebadged) and catalyst stopped working. Tried uninstall and reinstall but it happens always. I don't know what to do. Is it a corruption from windows 7 pro ? I can't understand that. Is it independant from the overclock ? I go to bed now, i'm tired

Anyone looking to take the plunge, there are AsRock X58 Extreme mobo's listed on eBay. $89.99, no I/O shield though.

I am so tempted to setup a hex-core system.

[Burpo]

Good find!

Add hexcore Xeon @ $80
http://www.ebay.com/itm/SLBV3-INTEL...425?pt=LH_DefaultDomain_0&hash=item51ca6938c9

at $170 it's hard to beat that combo.. You can add a SATA 3 port & USB 3.0 for another $14..

The machine i'm on now is a xeon with that board. very capable over-clocker, don't' be fooled

I should probably buy one as a backup, hah!

If it's a better overclocker than my current one I could trade for myself and give my kid my old one with the i7-920 I can't sell for a lousy $50.

I was able to push 4.3GHz with this X5660 without going over the Intel max allowance vcore.

Ditto, mine too. Is that the 1.35V allowance, the 1.5V one or the 1.65V inflationary allowance that Burpo originally set me up with?

Finally did my case fan/cooler fan swap. Now it can hit the high performance notes at less than 65 degrees in IBT and barely above 32dB. At idle, it's so quiet, I have to pop the covers to make sure something is spinning. Usually it's just my head.

I don't know you are talking about what he set you up with. I always keep my cpu vcore at a constant. Intel states not to go over 1.350v for this particular Xeon, the X5660. Most are the same but you have to check.

That's not the way intel designed the chip to work.. NEVER did intel say to keep vcore at a constant..

1.35v is fine for stock speed, but at the bclk we're pushing it's best to have adaptive voltage & Enhanced Intel SpeedStep® Technology enabled. Keep in mind, these were server/workstation chips & specs were conservative vs. desktop/performance.

I was referencing the top speed of my Xeon and the vcore that I pushed on the Asrock that people were talking about a few posts above. And also I am not running 1.35v at stock speeds, nor did I say Intel stated to keep the vcore constant. So please don't quote me on either points.

 

[Burpo]

Push them this hard & you're going to exceed specs.. just control temps..
X5675 @ 5.1Ghz.. 10 days ago at OC net..

 

[ClockHound]

Congrats, Burpo! This should be a headline on Anand today:

Ancient chip pulls 5Gs. On Air!

And only a teeny bit over the 'recommended' voltage limit.

Can you run CineBench at that clock and win a few places on the prestigious forum competition?

 

[Burpo]

I knew the X5675 would be the one to do it, but it's not mine.. Found that on OC net.. Yes, I still want that chip..

 

[ClockHound]

I was teasing...an obscure reference to when I first started with my 5660 - Burpo shared some tips - which I ignored. Then my fingers accidentally typed 1.62 in the bios, rather than 1.26V my mind wanted - the temps in IBT were hilariously off the chart! Me tripping over the case to pull the AC plug was pretty funny too.

It would be more impressive if that was 24/7.

suicide benchmarks runs are meh.

The more I check this thread the more I want to rethink my X5650 @3.66 - v1.21 / 64 max temp.
No matter how hard I already tried, it wasn't Prime stable at 4.0GHz (v1.35 was the max I had tried). Board is fine though, GB X58-UD5 that can do 215MHz clock easily.

I have an eBay feed for every-time a new x5675 is listed. I think they are going for around 175$

lol, ok, i remember that now

sorry for the/my confusion
