I had cause to put the 550 setup back together (testing a Palit GTX 460
and a SATA3 card), so here's all the info...

Within Windows, Vcore in CPU-Z is shown as 1.44V idle, 1.424V under load.

CoreTemp shows CPU idle temps are 11/22C idle (yeah right, something
weird there), 54/58C max (15 mins Prime95). Loads of headroom to boost
further, but not on this board (doesn't like really high bclks).
RealTemp shows the same max-temp info.

BIOS data (Asrock P55 Deluxe; CPU temp shown as 28C, with room ambient 20C):

Bclk: 196
PCIE: 101
BFG: ON
Spread Spectrum: OFF
CPU Mult: 24
QPI: 8.624
DRAM: 784 (DDR3/1568)
VDroop Mode: Without VDroop
V-Core: 1.41250
DRAM-V: 1.671
VTT: 1.384
PCH: 1.175
PLL: 1.895

Enhanced Halt State: OFF
Intel Virtualisation: OFF
HT: ON
SpeedStep: OFF
C-States: OFF

HPET: OFF
GFX: PCIE
LAN 1: ON
LAN 2: OFF
1394: OFF
EuP: OFF
SATA: AHCI
Link Power Management: OFF

Btw, here's a 3DMark06 run:

http://3dmark.com/3dm06/16465392

and a 3DMark11 run:

http://3dmark.com/3dm11/2755891

Both done with a single Palit GTX 460 1GB Sonic Platinum.

NB: my tests-jj.txt page has a section entitled, "TOMS CPU TESTS" -
these tests are exactly the same as those employed by tomshardware.com
for their CPU reviews such as the 3960X (they were kind enough to send
me copies of the test suites), and I run them in the same way, ie.
using an SSD to hold the test data so that storage factors are excluded.
Thus, my data can be directly compared to toms' CPU reviews; how my oc'd
550 performs for single-threaded tasks is particularly interesting in
this context (shows just how good an oc'd Clarkdale can be for use as
a general-purpose system).

Hope this helps!

Ian.
Using your settings a a guide, I was able to achieve 4.02Ghz stable with my i3 550.

Setup is as follows:
MB: Asus P7P55D-E Evo
OC settings I used:
BClk: 166
Spread Spectrum: Off
CPU Multi: 25
QPI: Lowest available instead of auto
Dram 1336Mhz
VTT: 1.385
PCH: 1.175
PLL: 1.800

So far running stable, Also on the Windows 10 Pro TP Build 9926

Hmm, with the ASUS EVO you ought to be able to go a lot higher than ~4GHz. Really, just about
any i3 550 should do 4.5 minimum, or are you going for a stock-voltage oc?

I have a few other better P55 boards, but atm they're being used for other things (i5 760 in one,
i7 875K in a 2nd, i7 870 in a 3rd); pretty sure I can get an i3 to 5GHz on a better board. Maybe
have a crack at this during the summer.

Anyway, with a multi of 25, I would have thought the EVO could handle at least bclk = 195.

Have you tried following Miahallen's guide to isolate bclk settings and max potential beforehand?
Helps sort out what the VTT needs to be, though I'd be happy with any VTT below 1.45 (it can
handle quite a lot). PLL had a surprising effect sometimes, but it probably varies chip to chip,
board to board.

I would but with a 650W PS, and still a stock cooler I don't want to push it till I get my liquid cool on it.

650 should be plenty, unless you're packing some heavy GPUs. I kinda steamrollered the whole power issue
for all the benchmark builds I put together, spent a while last year & before obtaining a bunch of new/used
Thermaltake Toughpower 1475W XT Gold PSUs, last one only cost 84.

Btw, my i3 550 @ 4.7 just uses an old TRUE and two fans, no need for water. though I might try an H80 if
I do go for a 5GHz run later.

Might give it a shot up to maybe 4.2 or 4.5 Kinda not wanting to push to much with a stock fan. And see how that goes.

Oh!! I didn't realise you had a stock cooler. In that case yes, keeping it on the lesser side is wise, though as long as
the temps are ok and you're happy with the voltages then it doesn't really matter.

Btw, this is the model of cooler I'm using:

http://www.scan.co.uk/search.aspx?q=LN26448

It's an older type, but still holds up well. Normally I get them cheap off ebay (usually for about 10 to 15), but there aren't so many
around atm. However, anything along those lines should do fine (I have a 2-fan Phanteks to sell cheap, but I don't know if that'd
be too big; very effective, quiet and cool though).

As for fans, pretty much anything. For pure benchmarking lunacy I use a couple of Yate Loon fans which'd blow the skin off
a rhino.
biggrin.gif
(total overkill btw; one doesn't need anything remotely as powerful to have an i3 running safely at 4.7, but I wanted
plenty of headroom, though in the event the limiting factor for oc'ing was the max blck the mbd could handle, not the heat).
If you want low noise, people will recommend Noctua (and they are very good), but they're ugly as heck IMO, so I use &
recommend Nanoxia Deep Silence 120mm PWM, half the price and just as good. Indeed, two NDS fans on an H80 is fine for
cooling a 3930K @ 4.8GHz (testing such a setup as I type), never mind a much cooler running i3 550...

Ah ha! Here are a few good ones for you:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=261755406399
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=291364407989
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=231464873910

The NH-D14 is obviously the best, but it's big, so check mbd compatibility before considering it.

And don't worry, I won't be bidding on any of them, I already have a stack of TRUEs and H80s.

The D14 is up there with the similarly huge Phanteks PH-TC14PE, in theory both quite a bit above the 212 EVO performance-wise (no surprise,
eg. the Phanteks has up to 3x 140mm fans). However, with temps around 60 then as you say nothing better is needed atm.

Most intriguing! Is it the sort of competition where the goal is absolute highest clock rates? Or is success measured
by various performance tests in different CPU categories?

Hard to decide how to judge such things I expect, eg. which is the greater achievement, a Clarkdale i3 at 4.8GHz, or a
G3258 at 4.8GHz. Much easier to do the latter, and it'll give better performance, but the Clarkdale is the tougher challenge.

Will have a look at the thread later; thanks for the notice & link!!

It's basically a XEON version of the i7 870. Personally I'd get an i7 870 if I was able to do so for a better price,
but $89 is quite reasonable for a chip that will at stock speed behave pretty much the same as an i7 870.

How well it would overclock compared to the 870 I cannot guess, XEONs vary in that regard.

What speed are you running your i3 at? I run mine at 4.7. Another upgrade alternative which should be cheaper
is the i5 760, a chip which easily oc's to around 4.4GHz , and you do have a decent board for it.

My site has various performance comparisons showing the i3 550 vs. other CPUs.

I have to say though, a far better upgrade for a system like you have would be a decent SSD, such as the
SanDisk X300 256GB. An SSD makes a huge performance difference to older systems, even though they only
have SATA2. I did lots of tests:

http://www.sgidepot.co.uk/misc/ssd_tests.txt

And when I replaced my the 1TB rust spinner in my brother's PC (i7 870 @ 4GHz) with a Samsung 840 250GB SSD,
it reduced the time for his favourite game to load from 2.5 minutes down to just 10 seconds.

Honestly dude, I would recommend fitting an SSD first, then do the CPU upgrade, though of course both would be ideal.

Indeed, that is a good price. Btw, have you checked that your mbd does support the XEON?
I don't remember if I looked it up last time. Some mbd makers don't tend to bother with
XEON support on consumer boards, with certain exceptions, eg. the Gigabyte GA-X58A-UD3R,
still highly valued for its XEON support. Asrock generally does, but ASUS' support for XEONs
is inconsistent.

What cooling system will you be using? i3s don't generate much heat, even at 4.2GHz, but
that XEON will need decent attention. At the same time, it's all to easy to end up with something
that cools well, but is noisy.

For me I found the best compromise to be a Corsair H80 but with the stock Corsair fans replaced
with Nanoxia Deep Silence 120mm PWM.

One last thing: do remember that even with a decent oc of around 4.2GHz, you won't see any
major speedup in single-threaded tasks, since you already had the i3 running at a reasonable
rate (if anything it's fortunate you don't have the i3 up where it can really go as then you'd actually
have a speed drop for single-threaded stuff, eg. my i3 550 is at 4.7GHz, and I have an i5 670 which
I'm pretty sure will reach 5+).

Either way, best of luck!!

Ian.

PS. Before the CPU switch, make a paper note of the old BIOS settings, save the oc profile, and
remember to shove the settings back down to standard levels. Also, after it boots with the XEON
for the first time, give it a while so it can reinstall the CPU-related drivers automatically. After a
reboot (when it states such is needed), it'll all be ok. Install the latest CPU-Z beforehand.

With the motherboard, from what I have read, with the latest BIOS Revision 1601 they added support for XEON, but didn't advertise. And with it being a P55 Chipset, most people running the P55 haven't had any issues running the XEON's. Cooling Im looking @ the new Corsair H80i http://www.newegg.com/Product/Product.aspx?Item=N82E16835181031

The i3 has a new home as soon as the Xeon rolls in, I will be sticking it back into the original OEM Gateway mobo I got it out of and will be building a machine from it for the wife. Thinking of 8Gb Ram, and little 240Gb SSD, and a Corsair 850 PSU for it. With a 2TB WD for data storage.

That's good!!

Seems to vary as to whether a mbd maker explicity supports them in their marketing material, whether they actually work or not.
Asrock usually does, ASUS/Gigabyte sometimes, others less so.

> Cooling Im looking @ the new Corsair H80i ...

Excellent! One thing though, after having dealt with more than a dozen H80/H80i/H100/etc. Corsair coolers, I suspect you may
find the stock Corsair fans kinda loud. I replace them all with Nanoxia Deep Silence PWM, but anything with good noise
behaviour but also good cooling will work well (the NDS fans are very close to the thermal/noise behaviour of the Notcua NF-P12,
but half the cost, though I'm not sure NDS fans are that widely available outside Europe, or as cheap). The difference is night & day.
Pity Corsair doesn't use better fans with these coolers, asotherwise they work very well.

Perfect! I've done something similar, built a system for my fiance using spares from all the benchmarking stuff I do, Ph2 965 BE,
GTX 560, SanDisk 256GB, etc.

Probably, but I am going to wait to get my water cool system first. Considering with the Turbo Boost, I am running @ 3.4Ghz. And smoothly.

Update
http://valid.x86.fr/3fwvsi

CPU-Z says 3.5Ghz, but BIOS reports 3.60Ghz and running stable air cooled. Might give this a run for a few days, if it stays stable, Ill leave it if not Ill just drop it back to stock.
