I picked up a Precision 670 on the cheap to just play around and i need some advice. It has a single 3.6Ghz 1M Xeon SL7PH and i'm trying to decide to either upgrade to Dual 3.8Ghz Xeon 2M SL7ZB's OR Dual 2.8Ghz 2 X 2M Dual Core Xeon SL8MA's. Which one will perform better? The higher clocked 3.8Ghz Xeon's or the lower clocked dual 2.8Ghz Xeon's?
i would recommend the dual dual cores, rather than the higher clocked single cores. for multithreaded apps, the dual cores should perform better.
So you are asking which of the following 2 is the "best":
If so, the answer would probably the the same as all the "E8400 vs Q6600" questions. What will you do with that machine?

File storage and burning of CD's and DVD's mostly. Right now it has 4 36GB 15K SCSI's in Raid 0 and that will be added too and a 32GB Patriot SSD for the OS. I plan on storing all of my Itunes and other video items on this workstation
I'd go with the higher clock cpu's. Unless you are doing really resource intensive stuff. Given these are your only options.
Also, don't expect the system to be all that much faster then it already is for normal things. Just expect it to run smoother and more stable. If you switch to the dual cores you'll probably notice the sytem isn't as quick but a lot more stable. Not really worth it...
Take your pick.
Why use scsi for storage? Aren't those drives expensive, noisy and limited in space? Also, raid 0 lessens access times on regular hd's especially when using more then three drives. Raid 0 with large regular sata drives get the job done better.
IMO, both system will be able to handle the load just fine, it seems to be very light load anyway. With more total cores (2x2 vs 2x1), you will be able to do more tasks at the same time and the system will run smoothly, but the tasks might run a bit slower. With only 2 cores running faster, the some tasks might complete faster, but you will not be able to run as many at the same time.
If you plan on doing media encoding (like ripping CDs to mp3 and/or DVDs to DivX/xVid), then the 2xdual core 2.8GHz will probably best since many encoders are multi-threaded.
Then again, how much would the upgrade cost you, because I'm pretty sure a i7 920 could beat that system for multimedia tasks?

SCSI's came with the system which is why i'm using them.

Both processors and vrm will run me 150. Not costly at all and i'm kinda leaning towards the Dual core's even tho i really want to get the high clocked single's.
LOL! Even my 4.2 ghz overclock e5200 couldn't come close to the multitasking smoothness and productivity of even a previous 533 fsb xeon. If you don't know what your talking about then take a back seat.
Also, Media encoding is different. Just get a lot of RAM and RAID 0. In this case, those scsi drives aren't a bad thing. But he didn't mention anything like this.
I've stressed a system like this, two single cores, and the system always shut down due to heat problems or limited RAM before the CPU's could be bogged down and your suggesting the dual core dual processor setup? Heh... That type of setup is for servers with lots of heavy constant i/o tasks.
Currently trying to put together a previous gen dual opteron system of some type. Very inexpensive and is said to run circles around the 775 type xeon platform. Platform tends to have a bit more options on overclocking as well.

Workstation came with 8GB's of ram so i'm not too worried about needing more. The heat issue is a concern tho. It has passive cooling and when stressed the system will shut down. I've been looking into some sort of new heatsink but we'll see.
Yeah, figured as much you would have heat troubles. And that is a 3.6 ghz cpu. There's really no way around this except significant cooling which basically costs a lot for the 604 socket when you need two of them if I am not mistaken. Limited options also. Dual core is only going to make it a lot worse. Even when it is only at 2.8 ghz.

I recently sold a dual Operton 275 setup on a Arima HDMAB motherboard and 4GB PC2700 ECC RAM. Now I'll admit I'm no expert in server hardware, but I do remember that you could load up the 2 Opteron's and the system would still keep on going.
And by loaded I mean all 4 cores running BOINC apps at 100%. My Phenom II 920 now is good as well, but I reckon it's not as smooth as the Opterons. :-)
The cost of running a Netburst based server and the productivity it generates is just plain disgusting compared to Core2 based Xeons and even old S940 Opterons. They're retired and are dirt cheap for good reasons. In fact people should PAY you to take it away them!
From what I've seen working as a SA almost all small companies have dumped them since early 08.
Probably the only thing that's still reusable is the E-ATX case which should be a good candidate for modding.

@jave200372
Exactly what I mean, so you've actually used it properly.
@Wuzy
It ain't that bad. Think of it this way, and the price on the new xeons are any better?
Back then one of the reason why you'd need a server motherboard is because of PCI-X for high-bandwidth controller cards. Now it's been replaced by PCIe which solves a lot of things.
RAM with ECC is supported by P35-X48 so no problem there.
So the only compelling reason to get a full server platform is if you need 2P or more in order to obtain more cores than what 1P allows.
For example Q6600 were being sold as Xeon 3220 (not a single difference) because you can achieve server stability with selected desktop/workstation components. With abundance of quadcore CPUs available today a 1P server with business-class reliability can be built very cheaply now thanks to this.

I like this old Pos netburst workstation. Haha
I just upgraded to dual "Paxville" 2.8Ghz DC's and it's pretty sweet for file storage and web surfing. It has a HD 4770 and plays CS:S very well. I have put money into it but i got the system for dirt cheap

While you are correct you are forgetting that there are two of them... Yeah, kind of forgot about that little detail...
Ever used a dual cpu system?
@Psychosaysdie
So you decided to get the dual core cpu's. Not a bad choice, both were good options really.

Hab,
The Dual's and high clocked single core's were the same price so i went with the dual's. Def improvement over the 3.6ghz single core.
What I was trying to explain is that the two of the singles cores at 3.6 ghz would have been a lot faster then two dual cores at 2.8 ghz.
But as far as stability and smoothness in a dual core dual cpu system, it's hard to comment on such a setup since I have not used it and there are no full reviews really on how a system like this reacts.
But as a lot of people say, usually there is no immediate difference between a quad and dual core that they notice at the same clock speed.
I know it's a huge improvement in stability and more responsive with two but do you notice initially it's not as fast as your single core at 3.6 ghz?
Turn off one dual core and try it out, you'll see what I mean.

I installed the 2.8 DP and it felt alittle less responsive then the 3.6 but overall was much better in CS:S. Much smoother gameplay, loading and a moderate fps jump. After installing the 2nd 2.8 DP made the system SO much better. I mean i understand it's very slow in today's standard's but it's not bad for what i need for it.
By all means that is not a bad system even for today's standards if you ask me. And a lot more and then some for your needs.
Yeah, either way, they were both good choices. Although if you were worried about heat issues on the 3.8 ghz, having two going at the same time instead one cpu taking all the computing load should have helped overall. Dual core dual cpu is definitely more stable then a regular dual cpu setup.
Well, good to see that it worked out nice for you. Have fun with your setup. Either way I would be a tadbit jealous, I always wanted to upgrade my old dual xeons with a dual or 3.8 ghz cpu's. Instead I'm currently trying to build an opteron system. Heh.

Thanks.
I solved the heat issue on one of the processors. I used an old waterblock and socket 478 mounting hardware from a "Coolit Eliminator" and to my suprise it mounted perfectly to the S604 mounting bracket.
I'm waiting on a second waterblock from coolit and the mounting hardware so i can tie it together in the loop i already have going. So far a triple rad with silent 120mm fans is keeping the first processor at 30c i / 42c l. The other processor with passive cooling is at 60c and rises quickly but should be fine once i get the waterblock in a few days.
The raid setup i have going "4 X 36GB 15K Scsi's" is loving the new found processor power. With the single 3.6 it was just plain suffocated. I have about 300 into the total system which includes the 4770 and the single SSD with the OS and it may not totally be worth it to many but it's fun and nice to have a separate computer to just screw around with. Parts are also dirt cheap which is great.
Nice...
Although, you might want to consider getting another ssd in a raid 0. I been reading that ssd's don't really show it's full potential unless you do this. Unless that is you got one of those expensive Intel ssd's.

Its on my list but i just haven't gotten to it yet.
Heh... Very nice...
Also, I noticed in another thread I stumbled upon the fact that you have an i7 rig.
Could you kindly note the differences between the two systems. I would like to know.
| habitat87 wrote : Also, I noticed in another thread I stumbled upon the fact that you have an i7 rig.

The first major difference would be absolute blazing speed.
The I7 is a whole different animal. Honestly i feel like my Xeon system feels a tad bit smoother when it comes to encoding and ripping but the I7 can just flat out fly.
