Xeon x5650 help.

[IKnight]

Excuse me if this is gonna sound stupid but I'm thinking of buying an X5650 and want to clear a few things up. 

First off, are they overclockable (via bclk) with an X58 board? From what I've seen online they are but just want to be sure. 

Secondly, do they work with regular DDR3 ram or do I need server style? Again, from what I've seen online, they do but just want to be sure. 

And thirdly, would an HX620 be enough to power one? (I assume it would work but, again, just want to be sure). 

Thanks.

1.No

2.Regular is fine but check with the Mobo

3.yes

hmm, thought they had unlocked multipliers...

I don't think there's a single unlocked xeon

From what I can tell, they aren't unlocked fully, BCLK is what is unlocked, so theoretically you just bump up the stock clock from its 133mhz speed to around 200 and you have a 4ghz hex core

From someone who uses an x5650

1. Yes

2. Depends on the motherboard

3. Yes

Bclk is pretty unstable woudn't reccomend.Like a .2mhz boost woudn't be noticable

I was about to say the same thing.  The unlock is limited.  For stability sake, I'd stick with the ECC if you do bump it up.....but not required.

Is the overclocking BCLK a thing with older xeons. how the hell do you have a stable PC

[the dutch guy]

yes you can overclock them. i am running mine on 4.05ghz and with 6 sticks of average ram. it can go higher but my ram will crap out beyond that.

 

ECC is stupid, it only slows down memory, especially on gaming systems it is beyond useless.

older LGA1366 CPUs.

aha thanks guys. Glad to also get some input from owners. Anything I should know before I get one?

Yes, BCLK only, I have mine at 185 when its normal at 133 but it's more dependent on the motherboard being capable of the heat. Lol and it's stable like any other overclock, but when you to the unstable area it's way more iffy.

damn, you for beating me again.   but, yes, look to the older LGA1366 socket XEONs

sorry fam . (and it also worked for the i7 9xx CPUs).

ah ok. I think the board I have should be good.

As I said, you do not have to have ECC memory for this, but it will hold the system more stable.  As someone else stated, the RAM and behave erratically from the increase.  However, there is reduction in speeds with ECC memory.  So you gotta weigh your options.

Not much, it's like any other CPU. Pm one of us if you need any help, at least I will be fine to assist with any issue so you may have. I have had one issue with the evga sli 3 And the asus saber tooth saying that it's ddr2 and that only 2gb are detected by programs like GeForce experience, even though all is usable.

From my experience up to 1.4125v is safe, probably more but I haven't tested further.

[NoxiousOdor]

I appreciate that everyone who responded for the most part was very informative and helpful. I've been a lot of places on the web where if you mention using older xeons (which are still perfectly good depending on the application) you get linched.

I think I'll just go with regular RAM for now. The overclocking will be more for fun than anything else to be honest.

I'll keep that in mind, and probably stick below 1.4v.

Thanks, and will do. Planning to run AMD so that probs won't be a problem. 

[the dutch guy]

don't go above 1.35. anything above that will degrade the cpu and give almost no real gains above that voltage, unless you need a space heater...

 

just cap it at 1.35 and see how far you can push it on that voltage.

 

ps: also lap your cpu! the 1366 series are more crooked then a politician. it can easly shave off 20c if you have a decent cooler. DO NOT DELID!

I agree, and that's why I like this forum so much. Everyone that responded has been very helpful and nice. Also why the hate to old xeons, they seem like great CPUs?

Ok, thanks. Il try to keep it as safe and stable as possible.

Yeah I have had that same experience, I really like it here. I'm not sure why there is so much hate, right now I'm building a dual x5690 build and I received some hate for it. But really why? For what I'm going to use it for 3.4Ghz with 12 cores and 24 threads is going to be perfect and I saved a lot of money doing it. I don't think I can overclock with the board I have but I don't really mind.

[the dutch guy]

old xeons are great. i bought my asus P6T7 supercomputer back in 2008 with a 920 and only upgraded the cpu to a 6 core xeon wich i got from ebay for 100 euro or so and with some overclocking can still kick the ass of a lot of current i5 and i7's from today.
