1366 X58 Xeon 5650

Interesting. Last night I played some WoW and was watching a Twitch stream and my CPU load was close to 90% across almost all cores. I need something that can improve that as I get major FPS drops whilst watching high quality Twitch streams. And provides a platform for now at least for a potential 980 SLI.
 
I just worked out my the build cost for my base unit and it came in at just over £420 using mostly second hand parts. It strikes me as an absolute steal for a base unit so powerful. If i put a USB 3 card and a 970 or similar in there id have no issue keeping it as my main PC.

i7 950 CPU , Asus Board, 6GB Corsair RAM £110
HIS 7950 £70
AlpenFohn K2 Cooler £32.50
Corsair Spec 03 case £44.96
Samsung DVD RW £11.86
Xeon CPU £50
12GB Kingston Ram £60
750w BeQuiet PSU £40
120GB SSD & 1TB HDD £50
SATA cables £1.48
USB Wifi dongle £5.99
Budget Keyboard/mouse set £11
Sale of i7 950 -£30
Sale of 6GB ram kit -£25

Total £421.79
 
I kinda assumed that because they are hex cores, they would be more suited to multi-threaded applications.

I can't believe how good these things seem to be. What sort of clocks are people getting on air?

Click to expand...

i was doing 4.4 @ 1.325000V, i have had 4 now and all did 4.4 with ease. the one i have now dose 4.61 @ 1.38500V but i dont like the high Vcore or been right on the edge of stable.
under game load 50 - 55c, the cpu's top out at 102c so... :)
i am now under water and i get 45 - 50c haha so yer, but it look cool ;)

the fact is your running a i7-920, sell the chip for around £25-£30 and buy an X5650 for around £50. So for a £30 upgrade it a no brainier

5670:

4.0 was easy, 1.26v
4.2 was less so, 1.33v for 100% stable.
4.4 wasn't worth the voltage bump

Also depends on what you class as stable :p (never crashes, ever is mine, so gradual increases from 1.31 -> 1.33 until no crashes for many more hours of DA:I)

72 is my max core temp on air.
 
4.4 is easy on the 5670, 200x22, 1.34v for me.
4.5 works too at 1.375v

Both IBT stable and mid 70s with max core at 80. Xeons are ok to 102c from memory so not worried about that.
 
Problem :( Need help!

I updated my P6T Deluxe BIOS to the latest version when my i7 920 was still in... It wiped all BIOS settings, but I think I put everything back to normal. Windows started without a problem.

Installed my x5650, and all BIOS settings reset again, so I put things back to normal again. In BIOS everything appears good, CPU detected, all drives detected, everything on the overclocking page set to auto except memory at 1.64v. BIOS reports CPU temp around 35°C.

However, I can't get into Windows! Blue Win8 logo and spinning circle of dots for a short while, then BSOD. Windows has tried doing a diagnostic and Start-up Repair, but no luck.

Thoughts and suggestions for a solution will be very well received!
 
Update... problem seems to be AHCI in Windows.

When I booted into Windows after the BIOS update, when all settings went back to default, I must have forgotten to set AHCI mode, so Windows disabled the AHCI driver.

Currently in Windows playing with the registry to get this driver re-activated.
 
Finally sorted :D If anyone else has the same issue with Windows 8, this solution worked for me:

Too late to get into proper clocking, but mixed results to start with. I tried 3.4GHz with everything at default, which my 920 was happy with, and the x5650 won't load Windows :(

I bumped vCore to 1.325 and went straight for 4.0GHz (20x200), and the system seemed happy doing general stuff in Windows, but failed the fourth run of IBT. Guess I need to do some playing around in BIOS. I spend most of my time doing low CPU intensive stuff, so I would like to find a good OC without having to push voltages too much.
 
Vcore - 1.35v
QPI - 1.35v
Ram - 1.65v

turbo - on
multi - 22
blck - 200
ram speed under 1600Mhz
Uncore 3200Mhz or less
QPU Low as possible but not slow mode

ever one of the 5 5650's i have had as booted and been stable at that.
when testing i just use super Pi, LinX and 3dmard in a loop. i have never had a blue screen
