Xeon L5639 Overclocking on X58

[TerryMathews]

what kind of power consumption do these things have at stock? wondering if one would be a good replacement for my athlon quad core in my video conversion box

Stock is 60w max.

60W TDP... and this is b4 intel went into the madness of SDP and pissed off everyone. :biggrin:

A dual cpu server.. meaning if u had 2 of these guys and a IGP onboard + SSD the system would pull under 200W fully loaded.

However Elf b4 u start piecing stuff out... check out the DELL's C1100 on ebay... they have ones with 2 hexicores, however even the dual quadcore L5520.. which would be 8 cores + 16 threads would gobble your athlon machine and then some, for under 400 dollars with 32-48gigs of DDR3 ECC Registered, and u even get 4 drive hotbays

Seems like the C1100's are all being thrown out of cloud servers to upgrade.. so u can find them on STEAL on ebay right now.
you cant overclock it.. however... with that many cores and ECC Registered Ram ontop.... i dont think u really would want to overclock it.

Updated! Post here when you get everything and I will add you.

awesome thanks!

i'm thinking i would need to learn linux as i don't think any of my windows versions are multisocket

:hmm:

180 day free trail with windows server 2012 ^_^

why do u think a boatload of people are having ReFS issues..
Just dont play with the new file format... and later on you can reinstall 2012 and repeat...
As long as the machine stays put in your house/lab... and isnt used in a business, but purely for the testing on your end, its allowed in TOS.

But that is microsoft's gift to people who are losing there technet account

180 day free trails now on some software now instead of having a technet account.


Those dells make awesome VM boxes... i have one with Vsphere installed running VM of server2012 which im about to give up on.. and server 2008R2.

PCs with multi-core processors:
Windows 7 was designed to work with today's multi-core processors. All 32-bit versions of Windows 7 can support up to 32 processor cores, while 64‑bit versions can support up to 256 processor cores.

PCs with multiple processors (CPUs):
Commercial servers, workstations, and other high-end PCs may have more than one physical processor. Windows 7 Professional, Enterprise, and Ultimate allow for two physical processors, providing the best performance on these computers. Windows 7 Starter, Home Basic, and Home Premium will recognize only one physical processor.

Just sayin.

Thanks for all the suggestions guys let me know if I'm missing anything here...

Here's an update on overclocking the L5639 on the ASUS P6T:

1. I'm still limited to 16x200 for full load situations. In the BIOS settings if I change the multiplier to 18, it posts at 3.6Ghz in the BIOS and shows 18-20x multiplier / 3.6Ghz-4Ghz at idle in CPU-z, but it seems like turbo mode is down clocking it to 16x under 100% load. This happens immediately and does not seem to be related to temps as the CPU is still relatively cool when it starts and I finish the benchmark (Cinebench) with my cores still in the 50c range.

Note: I think the same thing used to happen with my i7 920, meaning I could set 21x 200 multiplier in the BIOS and it would post at 4.2Ghz, but in Windows it would still run 20x multiplier under any sort of load effectively giving me 4Ghz. Maybe this is ASUS P6T issue with the turbo bins.

2. Setting 200 BLCK and Enabling all turbo / speed step features seems to be the best option on the P6T for all around performance.

a) With 1-2 Threads Loaded: turbo switches between 19x and 20x multipliers yielding 3.8-4.0Ghz

b) With 2-4 Threads Loaded: turbo switches between 17x and 18x
multipliers yielding 3.4-3.6Ghz

c) Above 4-12 Threads and you approach constant 16x yielding 3.2Ghz

Per the suggestions mentioned:

1. Unfortunately I don't see any thermal protection settings to toggle. Other than "Thermal Monitoring" under CPU settings. But turning it off or on doesn't make any difference in the behavior I'm seeing.

2. I believe my temps are good (25-30c idle and 65-70 full load) This is the same rig that I ran my 920 overclocked at 4.2 Ghz on 20x210 stable. (Using a basic Asetek liquid cooler like an H50)

3. I don't see any impact on stability above 200 block by upping cpu voltage (ie 1.45v has no impact over 1.35) where as 1.3v is stable at 200 blck Which is why I was wondering if there's something else, related to the blck that I need to lower the speed of or tweak.

Thanks

Yeah, I can personally attest to that fact about Win7 Pro and Ultimate.

Found this bit by google, it's about ocing the usual 920 CPU:

A: Some boards will throttle down the 21x multiplier if the wattage becomes too high. The culprits without public fixes are the Asus p6t deluxe and vanilla (The deluxe v1 has a bios available on the xtremesystems forum which can be crossflashed onto the v2 which will fix this problem) It really only becomes a problem at high voltages with high frequencies. Other boards have ways of disabling it.

I have such an option, too, in my bios, seems the P6T is a bad choice

But you can search for a modded BIOS including Gulftown support, maybe there is sth.

darn you aigo now i want one

likely lower than your current setup, and would be quite a bit faster i would think, 2 extra core awesomeness.
waiting to sell off my 920 and i will likely grab one of these and see how well it does on the 2 mobos ive got

i know who i quoted you formerly black mage turned waffle. aigo put the idea in my head to begin with.

I am up to 190x18... Stable for 24 hours@100% load.

some nice numbers
