Intel Core i7 920

[TouchuvGrey]

i just built a new computer. Asus P6TD Deluxe MoBo.
intel Core i7 920 cpu, 12 gigs DDR3 tri channel RAM
Nvidia video card with 1 gig DDR3 RAM. Instructions
SSE (1, 2, 3, 3S, 4.1, 4.2 ) EM64T, VT-x.

   What is the best app to run ?

It is usually a tossup between SSSE3 and SSE4.1.

I would go with SSSE3.

Given he has 12Gb i'd assume it has a 64 bit OS, so go for the 64 bit multibeam app. As Arkayn suggests the SSSE3 variety. Unfortunately there isn't one for Astropulse. It seems seti multibeam is somewhat quicker in the x64 version.

Same here. All mine have been upgraded now.

Running a standard non optimized client new computer
has accumulated 15,465 credits in 4 days. i'm going to
stay with this setup for a week or so and see how it goes.

    i will certainly run an optimized client soon, just interested in
documenting precisely how much improvement i get
from it.

AFAIK, you can let run 32bit software on 64bit OS.

I don't know what's included in the 64bit Lunatics Installer, but I guess the AP app is also there.


EDIT: If you installed opt. apps the CPU RAC will be the double. Also the performance of your GPU will increase because you will not calculate VLAR WUs (< 0.12x AR) which will make sluggish your PC.

RAC is imprecise by its nature. You could run offline benchmarks with stock and opt apps to see the difference.

You can normally run 32-bit apps on a 64-bit OS. What you can't do is run a 64-bit app on a 32-bit OS.

If i add a 2nd video card does it need to be the same as the 1st ?.

What percentage of the number crunching comes from the GPU
as opposed to from the CPU ?

What sort of gain could i expect from adding a 2nd video card ?

Just downloaded and installed Multibeam optimized app for
64 bit SSE 4.1

Nope, it doesn't have to be the same, but Boinc 6.10.x will only run the most capable by default,
you'll need to make a cc_config.xml (you don't have one by default) just copy the following, and paste it using Notepad,
then save it as cc_config.xml making sure it doesn't have a .txt extension, drop the file in your Boinc Data folder and restart Boinc.

Code: [Select]

<cc_config>
<log_flags>
<sched_op_debug>1</sched_op_debug>
</log_flags>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

Depends on the GPU / which project the GPU/CPU are running, expect some where between 50% and 90% total RAC coming from the GPU.

i currently have a NVIDIA GeForce GT 220 (1024MB) driver: 19045 video card.

Is there anything better in the USD $100.00-$125.00 price range i can add

using the cc_confic.xml  file claggy was kind enough to supply ?

i may end up overclocking the CPU and/or GPU ( s ), but not yet.

You have many options:
1) Keep it and with those $100-125 get a second card, 9800GT or GTS250 if the price is right
2) Sell it and add the money you get to the other $100-125 you have and get a GTS250 or even a GTX260 if you can reach it.
3) Stay as you are, keep your $100-125 and start saving for the new generation nvidia cards expected to come out in the March-April timeframe. Then you can also sell your current GT220 to add to your money for the new card.

If you want performance right NOW I would go to option 2. If you can wait a little I would definitely go to option 3.

i can get a Sparkle GeForce GTS 250 Video Card - 512MB DDR3, PCI Express 2.0,
(2) Dual Link DVI, SLI Ready  for $129.95 now
