What LGA775 cpu for DFI 875P-T ?

[eva2000]

I bought Oppainter's DFI 875P-T and it arrived a few days ago

Anyway I have my local disty doing the hunt for me for certain steppings/batches of LGA775 cpus as they had a new batch arrive late last week just need to find out what steppings/batch came.

According to http://www.intel.com/design/pentium4...pdt/302352.htm

seem to be the ones to look for...

I plan to utilise all the memory I have at my disposal so would like a good cpu that can do 14x multiplier as well as max out the cpu.

So my choice is between 3.2E, 3.4E, 3.6E ? The 'J' cpus don't seem to be available in OZ though as yet

I plan to use

Cathar's G4 Storm waterblock
Thermochill 120.3 with 3x 120x38mm Panaflo 103cfm fans
Clearfex 1/2" ID tubing
MCP600 or MCP650 pump

Any advice is much appreciated

The 550 and 560 are the only two that DFI supports the 14 multi on. If I remember right, mine is a CR SL7J8. Hope that helps.

550 or 560 with E0 stepping

550 or 560 with E0 stepping

The 550 E0 LGA doesn't support the 14 multiplier. Only the 04B (115W) CPUs support it. The 04A (84W) CPUs don't. The 550 D0 supported it because it was in the 115W envelope, but the E0 dropped it down to the 84W envelope.

Isn't 550 better due to lower wattage?

I would get the 3.6ghz with the E0 stepping, it should run cooler and the overclocks seem to be pretty good so far.

The 550 E0 should in theory run cooler than the 560 because it has the 84W rating instead of the 115W rating of the 560. However, you won't be able to use the 14 multiplier. I'm debating between the two myself.

Nice P4 560 D0 I got. With dryice 5200Mhz

[BigStan]

eva2000 ~ you're ekeeping us in suspense. What proc did you decide on?

[ar7786]

I'd pick SL8XX series. I doubt there is any relation between stepping and OCability.

don't know yet waiting for disty to get back to me as to what came in recent shipment to OZ

How about under regular cooling (air/water/phase)? Nobody runs a PC on dry ice.

[death metal]

i'd go for E0 =)....

[Xassius]

get a 560 E0 now and get the 3.73Ghz 1066FSB Prescott/Irwindale 2mb L2 Cache EM64T EIST uber cpu in February

Could you please explain what does it mean:

* S-Spec: SL832 *

I found P4 3,2GHz SL7PW 540J so i'm sure about E0 but what about EM64T? Where can i check this S-Spec thing?

This CPU does not have EM64T. To get the EM64T feature you have to buy a 6xx series proc. Like a 640 or 650 or 660.
