1366 X58 Xeon 5650

Try again!

Managed 8 hours without a single error, but then it rebooted in the night during testing :|

Upped the QPI one more notch and testing again :)

I've done all that before. Then I fire up a game and within two minutes the PC reboots.

Honestly these synthetic tests are a waste of time. Just go about your day to day business....

I do agree here just play games or rendering or whatever you do normally with your pc

But an operation has failed seriously enough to cause a reboot or miscalculation. I don't want a game to crash in the middle or write something bad to disk. 1TB of Steam is no fun on 4Mb :p

While that is true , what your doing isnt 100% that it still wont crash in a game
But if it makes you happy keep doing it each to his own and we are all individuals :)
 
I have been given (as in free/gratis :D) a socket 1366 motherboard (Gigabyte GA-EX58-UD5 ), i7-920 and Radeon HD4870 in a fairly monstrous Coolermaster Cosmos case. Looks like the motherboard should take an x5650 so I've taken a punt and picked one up along with 24GB RAM (2 x Corsair CMZ12GX3M3A1600C9).

Fingers crossed that it all plays nicely together, but if it does I'll have some powerful hex-core goodness for under £200. Will be a very nice upgrade from my current very ageing system (Q6600/8GB/8800GT :o)

[edit] The current HSF on there is a lowly Freezer 7 Pro which I guess may be a bit limiting. Any suggestions for a decent cooler which won't overhang the RAM slots, as I think the heatsinks on the Corsair which I have ordered is probably too tall even for the Freezer 7 Pro?

You're very lucky :) that board should kick some serious ass.

When overclocking my FX 8320 I could easily, easily get it stable running synthetic benchmarks. The only issue I had with them was heat. If I hit 73c my rig shut down, end of.

To that ends I did everything I could to make my rig stable when testing overclocks, then I found out I was wasting my time.

I could run Prime and god knows what not for hours on end, then I load up Crysis 3 and as soon as I got to a level that addressed all 8 cores it was crash heaven. Mostly I would get a really obnoxious buzz from my speakers, followed by a looped sound sample, then the BSOD.

The issue with synthetics is that they do not address your hardware in the same way that actual software does.

Asus Realbench is real software, simply being ran and monitored and the output logged. For example when you run the multi tasking test all it is is GIMP, Handbrake, a very high res video of some crackpots running a bench on LN2 and god knows what else they can throw at it. And that particular test was the acid test for me. If I got through that anything else was usually fine.

I'm a perfectionist :p

IT is my work and my hobby, I'm aiming for maximum speed at maximum stability, but it can take a while it seems :D
 
Got a X5650 for my old GA-EX58-UD5 system and after a ropey start (forgot to BIOS update/crashing on fail safe defaults, etc) I have managed to make some headway :p

Currently at 4GHz and will probably stick with this if it is stable for a few runs of IBT/Prime...

Also tried the Asus RealBench mentioned early in thread:

Xeon X5650 @ 4 GHz - GA-EX58-UD5 - 3x2GB Patriot RAM (1600MHz)

By comparison:

Core i5 2500K @ 4.6GHz - EVGA-Z68 FTW - 4x4GB G.Skill (1600MHz)

Ok, I'm happy enough now :p

Going to give a couple of hours of prime95, some realbench and hope for no reboots. No reboot today during testing after the tiny QPI bump.

I don't know about anyone else, but I've found these Xeon CPUs act very differently when unstable to my old i7 930 and i7 4770K. When those two CPUs are unstable they tend to give a BSOD in Win 7 but this Xeon X5650 often tends to just give a hard lock or reboot.

Its quite annoying because I'm about a cigar paper away from getting it stable at 4500MHz but still getting occasional reboots. I've tried upping voltages (both VCore and QPI) with the same results so I'm thinking something else is causing it. Ill have to fireup memtest86+ and see if its the RAM causing it.
 
Oh final test is Fable Anniversary, once it finishes downloading :)

Also noticed that I had less bsod and more rebooting without minidump or bugcheck info than when trying OC with my 960.
