1366 X58 Xeon 5650

Running Ubuntu on my dual xeon setup, but thought I'd join the party and share my benchmark on geek bench

That's a lot of cores

What mobo?

Do me a favour dudes - can folk check that they can wake their system from sleep ok? Ever since I have fitted the Xeon 5650, I can put the PC to sleep but when I tap the space bar to wake it up, the fans spin up and it appears to come on but I get nothing on the display and the monitor remains in standby mode? Worked fine with the i7 920. :confused:

Mine wakes from sleep OK. Any problems I've had in the past with this have always been an OS problem, resolved by wiping and reinstalling Windows.

Could be. But then when I got this Xeon last week all I did was remove the i7 920 and drop the Xeon in its place. Did nothing to the OS, and had no issues with the sleep function working with the i7 920.

Thought it may have been a BIOS setting I tweaked during the new over clock for the Xeon. It's no real biggy, the thing only takes seconds to boot with this 5650 in it anyway.

Hey all, could anyone let me know if I am gimping my RAM speed too much for my x5650 overclock (just under 4Ghz with 1.325 CPU volts). Had to set SPD multiplier to 6 to get it stable. Max temps on prime = 63 deg. C with Noctua nh-D14, but think its RAM speed that is limiting me. RAM volts = 1.66

Change Command Rate to 2T and push the bus speed again.

After almost a week of use my overclock has become unstable, not during use but my PC won't turn on sometimes

So I have dropped it to 4.2GHz and hopefully it will work for daily use.

It's a Dell T5500 Workstation. The plan originally was to get a single X5650 and mobo as I need the cores/threads for some stuff I'll be doing home server wise.

This dual CPU option came up, so it felt rude not to !

I do need to sort out considering an overclockable board for them (the idea of 24 threads at 4GHZ does appeal somewhat) but there seems to be literally 1 board you can overclock with them in dual config, an EVGA SR2, which appears to be as rare as unicorns.

Hey, thanks for that. I set mem Command Rate to 2 and upped BCLK to give 4.11Ghz. I got a Windows 10 'System Service Exception' on boot.
Any voltage tweak to cope that I may not have thought of?
Vcore is 1.325, QPI = 1.315

I'll have a fiddle here and there, as I'd really like 4.2Ghz seeing as my i7-920 was good for 4Ghz

Start here and work backwards in terms of voltage as mine i know i have to push higher / harder than most:

And expeeeeeeeeensive, I asked before if someone is running a dual xeon build on an SR2 but had no replies, so be nice to see what you get out of it if you do manage to find/get one.

Sh4rkie's settings seemed to work perfectly fine for me, Andy D. I'm currently sat at 4.2Ghz with no issues, low temps and awesome stability. :cool:

After I applied them, I gradually dropped back on voltage until I was happy with it, dropping from 1.40v Vcore and QPI to 1.30v for both.

Uncle_Gravy · 14 Mar 2016 at 16:11

Phew my £60 bargain mobo works, plunked a 920 and booted up to bios no problem, just need to hope the bios flash doesn't ruin my dreams, it's running Bios 1504 which is yonks old, so no wonder it never posted the x5660.

Draeger · 14 Mar 2016 at 17:24

Cool - let us know how you get on!

My system has been running for over a week now since I dropped the 5650 in, sat at an easy 4.2Ghz without batting an eyelid. Everything feels much 'snappier' and more responsive and I had a quick blast at Battlefield:Hardline and GTAV last night, was pleasantly surprised to find they both seemed to run smoother than the 920. These are simply awesome CPU's, don't see me needing to upgrade for a good while now although I might treat myself to a new GPU to replace my GTX760. Should have gone Xeon years ago!!

Uncle_Gravy · 14 Mar 2016 at 18:57

In the process of installing Windows now, but I was impatient and bought a H55 aio which I only had to pitch £25 for someone else graciously paid the rest.

Bios read running at around 1v CPU voltage and running 21ish degrees, nice start

But in terms of use, it's going to be paired up to a HD6850 and use as a video editing rig on Vegas, Vegas loves 6800 and 6900 GPUs

So if I can get a nice stable 4ghz I'll be a happy chappy, will require some assistance, never OC'd on the x58 platform

Draeger · 14 Mar 2016 at 19:05

Lots of good O/c'ing info in this thread and lots of knowledgeable folk too. I was amazed (once I got the right settings sorted out) just how easy it is to clock these things. And the temps!!!......amazingly cool running.

Uncle_Gravy · 14 Mar 2016 at 19:42

Woooooow, just running at stock 2.8GHz everything is soooo quick and snappy, Ok its running an SSD in SATA 2 but it honestly feels quicker than my 3770k system.

I'm well impressed, and its only cost me £150, thats CPU cooler, CPU and MOBO, I had spare parts lying around.

Still need to get it its own RAM as i've stolen the 8GB that's suppose to be in my 3770k system, but i'm happy to use this for a while

Haha and that's on 32bit Win 7 *Facepalm* my own stupidity for not checking the external cd drive I'm using, I upgraded someone's old netbook from XP to Win 7 and thought it was pointless upgrading it to the 64bit one.

I have a spare 6gb triple channel kit going on the member market this weekend if you still need one then.

I'll keep an eye out for it

update

Running Sony Vegas, stock clocks 2.8GHz and a 6850, its flying through a render, 7min 1080p 60fps 50mbps and its telling me it'll be done in 5 mins, My 3770k doing something similar with a GTX 980 would have taken 30mins, I'm so happy with this set up, Tomorrow if I can hit a nice stable 4Ghz with minimal voltage gain and nice cool temps i'll be happy.

Just tried it out as its important my system can wake up from sleep, especially Wake up on LAN and it booted up fine from the tap of the space bar.
