I saw the manual listed ECC

But does anyone know for sure if the P6T Series supports ECC RAM

If so that would be awesome

 

[Recon-UK]

No one needs ECC RAM for general use.

I saw the manual listed ECC

But it can use regular Ram too.

If so that would be awesome

Why?

It's readly cheap to aqcuire

Thats why i asked

I did some overclock on my E5-2670 and the results are S@³%&?%&$

Cpu running at stock + all cores enable.

View attachment 77642



CPU overclocked, just 6 cores enable, i wasn't possible to get that overclock with 8 cores enable.

CPU overclocked at 3.4GHz but just 4 cores enable.

It looks like the 2670 it is not good for overclock or maybe i am a bad overclocker

You need an E5-1620, E5-1650 or E5-1660 to have any kind of OC fun with SB-EP Xeons. All three have partially unlocked multipliers, with the E5-1650 and 1660 going up to x57.

Westmere can be beat, but only in single-socket.

It doesn't show what kind of cooler he/she has used.

That was my validation, and it was cooled with an H80i on the "Quiet Performance" settings with push-pull.

Amen

How much did you pay for the CPU?

Amen

$125. Bought it because I picked up a P9X79 at a local shop for about $75 and figured the Xeon would make a pretty badass machine. It did.

Don't get me wrong, I certainly wouldn't have tracked down and paid a good chunk for Westmere if I thought it was bad, but SB-EP and a few IVB-EP Xeons have partially unlocked multipliers and will just thrash Westmere.

The cheapest one here cost 169€

That's a shame. For awhile in January it was looking like X79 was going to finally take the place of X58 in the low-cost high-computing arena of the used markets, but then the prices on everything skyrocketed. X79 used costs more than X99 new in many cases.

Don't get me wrong but I bet a X5677/X5675 or X5690 would overclock higher.

Only because the multi on the E5-16xx series is limited under x60. I know on water alone the E5-1650 V1 can see 5.3GHz. Under LN2 Westmere will see higher clocks but in a daily configuration the SB-EP would likely be a better choice.

Any difference with H/T on ?

 

[Fouquin]

Any difference with H/T on ?

4.9GHz with HT on. The H80i was struggling at that point and I wasn't sure it would do it. Would expect to see 5.1GHz with a slightly larger AIO or a custom loop.

The nicest thing about the 1650 is that under 4.6GHz it only needs 1.2v. You can get a 30% OC with the voltage on the stock turbo setting.

 

[Recon-UK]

5ghz should be solid on that with a custom loop and HT on.

 

[FireFox]

Wait wait, maybe that's what i am doing wrong, when overclocking a Xeon is it better with or without HT?

 

[dorsetknob]

Slightly higher overclock = No ht ( +>2 to 300 mhtz on average )
more performance with ht but slightly more volts ( more power needed + more heat )

PS it also depends on what you get in that great silicon lottery

But i also noticed that he change the multipler to 50.0 while i tried to change it and it doesn't go any higher than 26, why is that?

 

[dorsetknob]

Not sure who /what your on about
different models have different multiplier's range available/set

Maybe i am setting the CLK to high, I had it at 106.2 and @Fouquin had it at 100.8.

There are two forms of overclocking, base frequency overclocking and frequency multiplier overclocking. Base frequency is the 100MHz number that you were playing with, while frequency multiplier is the x26 that you can't increase.

The Xeon E5-2670 has a locked frequency multiplier, I.E. Intel has locked it to x26 (26x100 for stock clock not including the turbo clock) so your option for altering clockrate is via base frequency only. Sandy-Bridge and later are hard to overclocking via base frequency due to a more complicated architecture, to put it simply.

The Xeon E5-1650 has a partially unlocked frequency multiplier, with a range of x8 to x57. This means to overclock the 1650 you simply increase the multiplier and leave the base frequency on 100.

 

[Durvelle27]

So anyone to chime in for ECC

 

[dorsetknob]

More Expensive than desktop..........> not needed
only preferred when used in server environment/applications
less easy to overclock.
