Xeon Owners Club

Had that on as well. Any other ideas?

Enhanced Intel Speedstep Technology?

Or maybe you have some power saving options in bios enable.

SpeedStep is enabled, all other power saving functions are disabled.

EDIT: disabled speedstep as well, load kicked in, multiplier dropped.
 
If its X5650 you wont get the top multi on full load

i dont have x5650 now and i dont remember that ever happenning to me.
 
Are you sure you have High performance on Windows power plan?

Maybe switch to balance mode and then once again to High performance
 
Thing is, mine doesnt even stay at 22, drops straight down to 20... is it the same with yours?
You have a P6T, you're hitting a TDP wall and the board is dropping the multi. To get around this, you need to flash the WS BIOS to it and enable "High TDP Turbo Mode" and it will hold the set turbo multi under load.

Ah, that makes more sense now, thanks :)
 
I hope i can hit at least 4.5GHz:D as i did with the X5677
 
4.75 ghz is my guess.......you should start a thread with a poll....:)
 
Subbing to this club/thread. I should have a year or so ago when I modded a P5Q socket to accept a Socket 771 X5470. Have it at 4Ghz and it's been rock solid for WCG crunching, but 4c/4t just wasn't cutting it.

Onto bigger and better with an EVGA X58 and an X5670 from this thread: https://www.techpowerup.com/forums/...920-3-7ghz-for-now.230017/page-4#post-3596695

Long story short. I had to mod the pre-Westmere motherboard by moving a tiny, tiny resistor to recognize the X5670 (that sucked, but it worked)

I can't get the chip past 3.5Ghz. I'm guessing I need to push more voltage through it. This was the highest I've gotten it so far:

I'll be messing with it the next few nights. Next plan is to drop the multi and raise the Bus Speed, and see what limit I can hit on the board itself.

Edit: What's a reasonable thermal expectation (degrees C) on these chips?
 
My ex dual X5677 OC'ed at 4.5GHz/4.6GHz 1.36V max temp 55c/60c

It seems that watercooling is the way to go with these chips, especially if you want to overclock it to the absolute max. My X5650 hits 90C quite fast at 4.2 GHz with a TPC-800
 
With my X5670 when i did this

I used a Corsair H100 with 4 fans on it. I think it hit 78C

Ive been running it at 4.0 ghz H/T on and im hitting 75C on the hottest core after playing GTA for a couple of hours and the hottest core at idle is 35C Its around 25C in my sitting room so im OK with that..

Fitting the double rad definitely improved things and i havent had a single drip. Ive got 2 fans in push / pull.
 
Well, depends what cooler you use.

Nice... I'm benching now with a stock cooler, but it's only hitting 75c under Prime95. Maybe I'm fooling myself and it's touchy with heat. It's going to be under a Scythe Ashura.

My x58 mobo is almost done for, so I'm going x79 next. Was looking at xeons, but seems only the e5-1650 v1 is oc-able. The v2 and beyond are not?
