"NEW" X58 hi overclock rig on Water Cooling...

[Fishman95]

Hi,
I`m planing to set up X58 rig.
Could you please give me some advice.
What are the average overclocked speeds on wather cooling for:
5650
5660
5670
I`m planing to go closer to 5 than 4 GHz.
Which bord is worth to take?

Is it posieble to overclock close to 5GHZ on dual CPU boards?

Thank you in advance, Fishman.

To get close to 5Ghz I'd recommend the X5675 as it has the highest multiplier of the EP Series Xeons. Asus, Gigabyte, MSI, AsRock, even BioStar & some EVGA boards overclock pretty well. Dual processor motherboards do not allow much overclocking (if at all). With good memory, good power supply & a good board (properly tweaked) and water cooled cpu, you may be able to run 200 BCLK X the multiplier of the individual cpu's, should be close to something like this.

X5650 X 22 = 4400
X5660 X 23 = 4600
X5670 X 24 = 4800
X5675 X 25 = 5000

Don't be afraid of a Foxconn Bloodrage either. Even the 1.0 boards do 220bclk no problem. v 1.1 boards have a fix that allows PCIe > 102mhz which helps get higher then 220bclk.

There's only one board that can oc with dual cpu's: EVGA SR-2
But it's expensive.

If you want very high oc X5670 or X5675 is the best choice.


If you want to play games one X5670 with high oc is the best choice, but if you're going to use a lot of multithread/rendering software 2 cpu's, even without oc, is the best bet.

Let's not set his expectations overly high guys, fact of the matter is no one on here yet has been able to get "benchmark stable" at 5GHz. Beyond that, AFAIK I run the fastest 24/7 speed at 4680 with all six cores locked in at 24x195. Fact is most people across the various forums are settling in at the 4.2-4.4 range, it's still a heck of a bargain even at that for a six core chip.

Now I have made a slight cooling change recently and may try to take another run at 5GHz, though I doubt it will change things. I moved my X58 stuff into my HAF XB along with the H100i after moving my X79 into my new Case Labs S8/custom water setup.

First of all thank you all for answer.
Regarding the processors:
X5650 2,67 (133*20); turbo 3,06 (133*23)
X5660 2,80 (133*21); turbo 3,20 (133*24)
X5670 2,93 (133*22); turbo 3,20 (133*25)
X5675 3,07 (133*23); turbo 3,20 (133*26)

So lets say that we will set FSB to 220.
In this scenario x5650 will go 4,4Ghz with all cores or goes to turbo and two cores will reach 5,06Gzh. I have seen souch numberes. In the same situation X5675 would reach creazy freq - 5060 all cores or 5720 turbo. It is imposieble to use without LN2 cooling. But if we would set fsb to 195Mzh than X5675 would reach 4485 all cores and 5070 in turbo. It might be possieble... We would also have a lot of FSB margin to go up with Turbo off.

Another think is finding good procesor and now new quastion. X5650, X5660, X5670 came in the same time - March 16, 2010 while X5675 came February 14, 2011. X5675 should be better but is it the right thinking?

Regarding the mather boards:
After some research I know that there are mainly 2 boards to dual Xeon set up:
a) ASUS Z8PE-D12x - very good one but no overclocking
b) EVGA SR-2 -great one for overclocking.

Mk_pt you are right. First of all I have to ask myself I need 12 cores. The answer is I DO NOT. Most of the softwere I use one core. It would be nice to chave such a monster machine like 2xX5675 and overclocked but the cost would be very high...

I`m thinking about taking x5675 for about 250$. But I`m still not sure what motherboard I should take....

Generally speaking, you're not going to get 220 BCLK with these CPU's as a 24 X 7 stable PC. Not many people use 200 as a 24 X 7 overclock either. Considering they're designed to run at 133, we're pushing them pretty hard already..



Don't pay too much for the X5675. $185 on ebay & he has a few..

If you just want to run 2 CPU's, there's an Intel server board on ebay with quad cores & RAM..

I`m trying to fond Asus Rampage II Gene and put it to nice small case. It`s imposieble to find this board in europe in resonable price. Still searching...

 

[Burpo]

They are not cheap..

Sorry, I ment Rampage III gene....
It will take me time to to get all parts but I will not rush. I dont see a point to overpay for old platform...

HI,
I have found interesting processor. It`s x5675 ES steping B1. What do you think about it?
THanks for supporting ;-)

 

[Burpo]

If it is Q4SF yes, get it.. I see them on ebay for $150 (last one).

 

[Mk pt]

Skip that X5675 ES and search for a X5675 non-ES.

X5675 ES TDP: 130w
X5675 TDP: 95w

Xeon's ES only for newer socket than 1366/ X58.
All X58 xeon's can overclock, for sockets after 1366/x58 to overclock a Xeon it must be a ES.

 

[Fishman95]

It is Q4SF 95W. Is it better than regular 5675?

 

[Burpo]

It's the same.. Only the earlier ones were 130 watt with A0 stepping.

If you don't need that many cores you can get a X5667. They are the same speed as a X5675 but only have 4 cores instead of 6. The advantage is they cost almost half as much as the X5675. Here is one for $95 http://www.ebay.com/itm/INTEL-XEON-...SOR-/380990416325?pt=CPUs&hash=item58b4cc65c5
