    I have 3 Pentium D 920, 2 boxed retail samples, and 1 ES. All of them overclock like hell. I show below results with 2 retail 920.

    System:
    Pentium D 920 (2.80 GHz, multiplier locked, no HT)
    Asus P5WD2-E
    2 x 512 MB DDR2 6400 4-3-3 (running at 4:5)
    CoolerMaster Hyper 6+
    550 Watt PSU

    It seem the 920 can be overclocked with good air-cooling to 4,000 ~ 4,100 MHz. All 3 samples I have do boot into XP at above 4,300 and allow to run some simple tests at this speed. It seems 100% stability is given at around 4,000 ~ 4,100 MHz. I have one of the 920 now running for more than 24 hours ar 100% load on both cores.

    Don't look any further, that's the CPU to go for. :leet: Best processor I have used since a long time. Intel's move to 65nm has paid off. The 9xx series is excellent. :thumbup:

    100% stable at 4060 MHz, 24 hour test with F@H with 100% load on both cores

    hey chainy looking good there

    what's the default vcore on those CPUs.......would it be 1.3v that the box states?


    looks like we're crunching the same proteins there heheh...except the amd dual core is kinda kicking that Pentium D ass a little heh even at 2.54GHz :p ....just doing some testing on these speeds

    I would say 5C. The point is, you can't directly compare it at the frequencies I showed above, because a 90nm 820 not even remotely would make it stable to 4100 with aircooling.

    I am sure, we will have a lot of fun with the 920 over the next months. :leet:

    Very true, looks like the CPU to have for the next six months or so.

    nope, that's not the same units I'm chrunching, they are unique. And if you want I can show you daily outputs with dual core P4 9xx in the 400 range, with HT enabled and 4 instances running, no AMD CPU can do this. Want to see? :p

    yeah i know i've run dual xeons and they kick arse.....i thought one of the proteins was the same there......p2306_BBA5_pfold in water

    It seems the work units are all slightly different. When I was running QMDs, I got every time different daily outputs.


    The main point is still HT: For a P2306 protein unit you need around 23 to 26 minutes per unit with a X2 at 2.5 Ghz and a 840EE at 3.7 GHz, but I can run 4 of them and you only 2. ;) (that's with a 840EE, not with 920). And keep in mind that I can probably buy 2 x 920 for your X2.

    Here you have it, at 3.7 Ghz the dual core Pentium 4 is fasting as fast as a X2 at 2.5 Ghz, but I can work 4 units, and you can't. On a good day it's 500 points per day, and with QMD I could make 800 points with this system. No way that you can beat this with a X2. And the CPU is by far not maxed out.

    i've been checking out p2306 proteins and longest i've seen them was high 14m per frame :confused: not 25m

    in australia where most of these users live.....cheapest Pentium D 920 costs $378

    and Opteron 165 costs $483

    not double the price but certainly a bit pricier than 920..........but when you grab a $90 mobo for AMD or $200 for Pentium D 9xx series it misteriously becomes similar

    but when you start comparing Extreme Edition CPU to a basic 165 you get into a lot of financial trouble there......as you can certainly build a couple of decent AMD rigs that would blow it out of this world for the price of that very expensive 955x

    anyhow it really isn't an argument about who's toy is better just thought i make an observation.....

    Then, why do you need 25 M as shown in your screenshot?


    You points are all valid, but things are moving on ... AMD will soon change to DDR2 and that will boost performance, and Intel prices for 9xx series will come down a bit (I pay 340$ here), even in AUS, it's still a brand new, just launched CPU. Then soon there will be 965 boards, that cost you not more than currently a 945 board, and the cheapest goes for 145$, and so it goes on.

    That's also correct, but the same holds true for a FX60 which is even more expensive ;). We all look at the affordable entry level stuff, and I think with the 920 Intel has good dual core offering here, considering the price and this enourmous OC potential. I would not be surprised if we see soon a 920 running at above 5 Ghz with a Vapochill.

    I have to return 2 of them, they are for the upcoming Presler review. I bought one, and when it overlocked so well, I thought I better verify this with other samples. I have a vendor here who gives me the stuff, kindly also a FX60 and a board for a few days. :leet:

    /me is jealous.

    Well when i've paid my $1600 car insurence and $1000 for x-box 360, in 2008 ill be able to afford a 920! I can't wait.

    BTW, in your 955/975x overclocking you used the Coolmaster Hyper 6+, yours is copper from what i see, well whats the difference between these two:

    Coolermaster Hyper 6 P4/K8
    http://www.pcalpha.co.nz/product_info.php?cPath=27_35&products_id=485

    Coolermaster Hyper 6+
    http://www.pcalpha.co.nz/product_info.php?cPath=27_35&products_id=1249

    Because the 6+ on their site is alloy...

    You are right, I mixed up the time for the frame and the workunit ;)

    Below is a HT enabled EE running with several of these Proteins, as you can see, it needs around 24 M for one frame, when running at 3.7 Ghz. But the daily out put is almost 80% better than your X2, and that puts the impact of HT and the price somehow into perspective ;)
