1366 X58 Xeon 5650

I have a I7 950 at stock speed of 3ghz and I am using a Nitro 390 8gb with no issues.

I can play the division, killing floor 1 and 2, all the lego games for my son diablo 3 etc

@Stu being that I'll be running two on a Supermicro board there's no chance of clocking it up, was just curious as to if the higher clock speeds would have a noticeable increase, a pair of matched x5650s seems to fluctuate around 40-60 whereas x5670s are 100+.

Prices are close comparing x5650 and x5660, but normally jumps in price for x5670.
 
Yeah the pricing seems to be jumping around a fair bit, think I paid 40 for an x5650 in January and now it's 20-25. You think it's worth paying for the marginal differences between the 5650/5660 or just stick with the 5650?

Recently bought an X5660 @ £23 for my brother, not sure the X5670 or above is worth the extra (if you're overclocking).

I'd just go for the X5650/60, how good they are is down to the silicon lottery as we all know.
 
not oc'ing, dual socket supermicro board. have seen the higher chips going cheap but i need two of the same model which could be a hassle when buying two chips separately. i think two 5650s will probably be fine though.
 
I built my first ever computer yesterday. Super happy that it booted on the first try. I did make some mistakes along the way, which I'll bare in mind next time. But that's to be expected when you're in new territory.

Right now, I'm running the X5550 before I install the X5650. I have the X5550 overclocked to 3.9ghz at 1.28 vcore after looking at a couple of guides. It's running too hot at the moment though. Temperatures are low 90s on Prime95 blend test. So I'll try to sort that out before I proceed.

As a newbie builder and overclocker, I'm happy with yesterday's result. Hopefully I can get this X5550 to 4ghz before I proceed.

Here's what the build looks like...

Very nice looking build, compared to my case which is a mess of wires. I've tried to improve it several times but there's only so much I can do with annoyingly little cable management built into my case.

Surprised it's running so hot though. It's 45 nm so will run hot regardless but 1.28 V is nothing for those chips so 90+ in Prime during winter is unusual. How did you do the TIM? Regardless it should be better with the X5650.
 
Thanks.

I put a good pea sized amount and screwed the heatsink until the screws stopped turning so its sitting flush on top. But I have my doubts with the coverage on the CPU. It was idling at 30°C at stock before I did anything. Is that normal?

When I swap the CPUs I'm going to spread the thermal paste if my first application didn't cover enough. Just to be safe.
 
Finally got my rig built and up and running. Had to find coolers for all the motherboard chipsets as it came with ek blocks, so I've got all enzotech coolers now and it's working a treat so far. X5650 clocked to 3.8ghz. Only used cpu-z stress test so far but it's 19 degrees at idle and 46 under full load on all cores.
 
This X5550 does not like 4.0ghz at all. It's fine at 3.9ghz. I lowered the vcore to 1.23 and runs fine. I will try lowering it some more tomorrow. Prime95 temps peaked at 80°C. But in game temps peak at low 60s. Not bad for a £4.25 secondary chip. I will try to compare this little guy to the X5650 to see how well it stacks up.

Thanks, Ste. :)

I have 1.46v ish going through my E5649 to get it to 4.1ghz.. Seems high but its been happy like that for 2 years now and temps with a H50 are about 70c full loaded, 50c gaming
