There is a very good reason the ROG motherboards don't have this feature and I mentioned it here
Who the hell buy's Xeon to overclock anyway? These processor's are expensive, designed for servers, and not intended for overclocking. Who the hell even has the money to blow on these processors to even do such a wasteful thing?
Okay, I'm a bit frustrated here... I got my x5670 in on Friday, and just tried to drop it in on the first rig in the signature (Asus P6T Deluxe V2 mobo for reference) - and nothing. I tried the standard removing all but 1 stick of RAM, remove CMOS battery, etc, and all it would do for me was power up for ~1 second then shut down. All fans would spin, power & HD lights would flash, but nothing more. Pulled the x5670 and dropped the 950 back in, and it fired right up. 10 seconds in the BIOS resetting the date and reloading my OC settings, and I'm right back here running 3.8 at 34*C at idle... Any suggestions for something I might have missed? I'm using the 1108 BIOS - didn't update to the 1202, as it looked like the only thing it did was fix a keyboard issue... Does it also sneak in Xeon support? I'm about ready to send this back and pay the $10 restock fee rather than fight with this much more, but like often happens, I'm hoping one of you might see something stupid I overlooked in the process and while reading this thread...
Have you found a way to get the 22x multiplier working? I have the same motherboard and it won't stay at 22x for more than about 10 seconds without throttling down to 20x, despite using sensible voltages (~1.25 V) and low temperatures (55-65 °C).I have the Asus P6T deluxe v2 you have to update the bios to the newest one.
Then put the new chip in, pull the plug from the wall and push the start button to discharge the caps.
Reset the bios and it will work.
I am running a x5660 and I had a x5650 and they do woek real well on that board.

This is the dumbest post i have ever read on hard forum.......And i think everybody here would agree its true.......i had to read a few of your posts to figure out what kind of guy your are and its all there in black and white.....Do us all a favor and think about what you post cause thats just plain bullshit and terrible if not intentional misleading advice.....try to argue and im betting many will flame you for shit advice like this...People here know better and i plan to make sure your potentional customers know as well
i sold my last hexacore here in under 2 hours (for exactly what i paid for it) so don't tell me that hard ocp is not a great place to sell goods...as long as its priced accordingly....a 4 core xeon is worth maybe 40 bucks like it or not and its not even in the same category as the 6 core xeons like the x5670 series

The original 0006 BIOS does not work with six core Core i7 or Xeon processors. I've also tried adding the 32nm processors microcode support to the 0006, but it did not work, either. I own the P6T Deluxe v1 board and it's been two months since I crossflashed it with P6T WS PRO BIOS in order to be able to lock in turbo multis under load just because my motherboard does not "like" high BLCK. You can read more on crossflashing here.
Holy Crap, you are my hero! I crossflashed over the the WS bios you had posted and viola, the 18x multiplier on my L5639 sticks under full load! Now to toss in the x5670 I just bought and see what it can do. I already know the board is stable at a 211 BCLK, so here's hoping for 5GHz!

Nice to hear it works nicely on your vanilla P6T board. 5GHz is very steep, let us know how close you can get.
The only thing that's a little weird with it is that the "High TDP Turbo Mode" option only shows up is if I leave the overclocking setting on Auto. If I try to dial in the multiplier manually it disappears and I haven't tested whether or not I can still lock in the turbo multiplier when it's in manual mode. More things to test I guess.
Don't worry, you can easily punch in multiplier manually and still have the "High TDP Turbo Mode" working even though it doesn't show up. Just make sure it is enabled before you set multiplier manually.
This is interesting. Currently running an 860@4ghz and a P55A-UD4P. A quick look on ebay and I can grab to a x5650 and GA-EX58-UD4P for a total of about $10 after selling my current board/cpu. It looks like it'd be quite an upgrade if it clocks well.
I guess my only concern would be the bios and whether it has been updated to the latest version.
I'm guessing most of these boards can run triple channel with 4 dimms, but the last channel will be shared between two dimms?
You can't be sure about BIOS unless seller sells as a kit and states support.
Also you can't do triple channel with 4 films, it would run dual channel with 2 sticks per channel. Triple channel would need 3 or 6 sticks. I once put 2 triple channel kits together with 3 dual channel kits for 6 total
Yeah, it might be a bit of a risk.
I thought one channel would just run interleaved? If there are four 8gb chips like so:
A1, A2, B1, C1
24gb should be running in triple channel and 8gb would be running in single channel. Maybe I'm misunderstanding something?
My understanding is interleaved is within a stick of ram, basically it comes to number of connections. Multiple ram channel is like RAID for HDDs, you can't run raid 5 with just 2 drives and say just used last 33% of first 2 for that last 3rd of space.
Make sense, careful with 48gbs though, even 24gbs is pushing limits for x58 and some boards even struggle with that. I've seen folks getting 48 to work but seems very YMMV, esp trying to overclock on top of that

This is exactly what I did. I sold my Core i7 870 + ASUS P7P55D PRO combo for the price of a manufacturer refurbished, spotless ASUS P6T Deluxe + Xeon X5670 processor. I know I probably lucked out on the motherboard because it cost me just $100 bucks and looked just like new.
Yes, these boards should do triple-channel with 4 sticks installed, however, there will be some limitations. Here's what my ASUS User's manual says: "You may install varying memory sizes in Channel A, Channel B and Channel C. The system maps the total size of the lower-sized channel for the dual-channel or triple-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.". So at first I took all the memory from my P55 machine (4GB+4GB+2GB+2GB) and threw it into the X58 one in following configuration: A0-4GB B0-4GB C0-2GB A1-2GB. The computer booted without any problems and reported I was running in triple-channel mode. Anyway, I few days later I ended up selling those two 2GB sticks and getting one 4GB module.
You'll definitely notice the difference in that kind of apps. Apart from that, expect the Xeon to run much cooler than the i7 860 you have now given the same core speed.
That's.. Surprising given that it has 2 more cores.
2 more cores but built on a 32 nm process rather than 45 nm, hence less heat dissipation. Unfortunately that was pretty much the last process jump that came with an automatic reduction in heat, as became evident with Ivy Bridge.
