After installing new driver 11-12_agp-hotfix_xp32_dd_ccc.exe
cpu usage for primegrid's ati app is now reduced by 50%
have a look at the progress..

modify some days later:
CPU usage is at 50%, but runtime increased from 13800 sec to 15000 sec, not so good

HD4670 AGP awaiting 1 Mio pg on 28th january

[_heinz]

A short look at V8-Xeon
NVIDIA GPU 0: GeForce GTX 570 (driver version 26658, CUDA version 3020, compute capability 2.0, 1248MB, 1603 GFLOPS peak)
NVIDIA GPU 1: GeForce GTX 470 (driver version 26658, CUDA version 3020, compute capability 2.0, 1249MB, 1308 GFLOPS peak)
NVIDIA GPU 2: GeForce GTX 470 (driver version 26658, CUDA version 3020, compute capability 2.0, 1249MB, 1326 GFLOPS peak)

I have an old BIOS on one of the GTX470, and this card shows some higher temps as the other with newer BIOS.
Next I will flash the BIOS of my graphicadapters. Perhaps I can squeeze still a bit more out of it.

btw today 20th of january I got 250 Mio total credit 
Current Credit (based on incremental update) 250,641,103.33

25th january, v8-Xeon today tophost_pg_number_6
The machine is crunching alone on its GPU's, no cpu work is activated.

If you do'nt know it, have a look at the Fermilab 
have fun to explore it

HD4670 AGP awaiting 1 Mio pg on 28th january

I got it on 27 january HD4670 AGP 1Mio pg

boinc stats shows pg_id=232541
Summary we can say HD4670 AGP can do ~20000 pg credits daily continous.

If we would have now a SSE2 OPENCL astropulse app we could be happy.

 
 modify:
today 31th january I stop crunching on HD4670 AGP, it is proven.

Trouble with the internetconnection over a whole day, no internet, no telefon, not enough work on V8-Xeon.
And now as internet is back V8-Xeon produces more results as I can upload, the queue to upload increase slowly....

Yesterday V8-Xeon server get disk error on partition where BOINC is installed. I use a own 2GB partition still for BOINC. I had to reformat it and installed BOINC again.  Bad block is shown in harddisk 0\DR0.

Further I have some CRC sector errors in C so it was not possible to make a image backup. Looks like I had to low level format the disk in the next future. 

btw. today BOINC total shows 277,331,153.42

Be warned to run Cullen/Woodall(Sieve)1.12 cpu application! You must have a very good cooling solution!
It heated up the FB-DIMM's of V8-Xeon to 118 grd Celsius.

Friday 24th February: shutdown V8-Xeon to clean and repair the disk.

[_heinz]

I was surprized about the dust bunnies as I opened the case. Last cleanup was in november short time ago. I cleaned all especially the two big CPU cooler and the fans. Dust was behind the fans. The FBDIMMS looked clean so I did not take it off.
As all cleaning work was done I started the server and it booted OK.
I changed the disk0 against a other one, I had installed W7 last year.
( I have 3 start disks with different OS, Vista Ultimate, W7 Ultimate, XP64 Professional)
W7 must be activated again and downloaded some days a lot of updates, which was a pain behind my slow internet connection.
Now I have all update and my developer environment is installed again.
VS2008 Professional + Intel XE 2011 + CUDA 4.1

Flash BIOS of GTX470
Next step was to change the BIOS of Graphicadapter 1 (GTX470) with newer BIOS from Graphicadapter 2 (GTX470)
Todo this you need GPUZ0.5.9, and nvflash for windows and NiBiTor v6.03.
DOWNLOAD: NiBiTor v6.03 via mvktech.net -> Klick
First step is to make backups from your original BIOS of all graphicadapters.
This can be easy done with GPUZ0.5.9. Save the file as .bin or with nvflash itself.
You can later edit .bin files with NiBiTor to make necessary changes and store `s .rom.
Install nvflash and NiBiTor best into your user account directly. This store the backuped original BIOS on the same place.
I used nvflash to make the backups. I made 3 links from nvflash with added backup entries, for each adaptor one.
Adaptor 0 GTX570 BIOS:70.10.17.00.03(P1261-0005) Device ID:10DE-1081 backup as orig0.rom use link"nvflash 0 backup"
Adaptor 1 GTX470 BIOS:70.00.21.00.03(P1025-0006) Device ID:10DE-06CD backup as oirig1.rom use link"nvflash 1 backup"
Adaptor 2 GTX470 BIOS:70.00.1A.00.03(P1025-0006) Device ID:10DE-06CD backup as orig2.rom use link"nvflash 2 backup"

to make the backups for each adaptor click easy on the backup link. If you have done it for all three, You will find the backupfiles orig0.rom orig1.rom orig2.rom in your user account.

if we look now with NiBitor to orig1.rom we see under Adv. Info:
Device ID:06CD
Sub Vendor ID:10DE
Sub System ID:079F
Board ID:5E00

if we look with NiBitor to orig2.rom we see under Adv. Info:
Device ID:06CD
Sub Vendor ID:10DE
Sub System ID:079F
Board ID:DD00

If we want to use the BIOS of orig2.rom to flash adaptor1 the original Board ID of adaptor1 should not be changed, so we must edit Board ID:DD00 to Board ID:5E00 and save as 470-1mod.rom nibitor_470-1mod_changed_Board_ID_5E00
Now make a link"nvflash 1 470-1mod" of nvflash.exe using adaptor1 with file 470-1mod.rom
Now make a link"nvflash 1 original" of nvflash.exe using adaptor1 with file orig1.rom
We can now flash adaptor1 with the modified Bios from adaptor2 by easiely clicking on the link "nvflash 1 470-1mod". A DOS windows opened, nvflash.exe is executed and you must confirm with y to flash. After some seconds the flash is done DOS windows closed automatic and the graphicadapter resets. Now call GPUZ and you see adaptor1 has the new same BIOS as grafikadaper2.
For the case something go wrong we can easy click on the link "nvflash 1 original" to write the original BIOS back to adaptor1.

This all can be done under W7 full operational, but BOINC should not run any GPU-apps on the grafikadapter to flash.
I can confirm that this  works on my machine V8-Xeon.

And as always: You do all modifications on your own risk.

I restarted the machine and crunched some hours under full load, but adaptor1(GTX470) with the new BIOS run up to 110 grd Celsius.
This are ~20 grd more than with the original BIOS. Reason unknown.....
So I flashed the original BIOS of adaptor1 back.
Now adaptor1 show  evga_gpu2_90grd under full load as before.
See v8-xeon under full load
interesting point are the temps and RPM of fans of the 3 grapicadapters.
GPU1 3240 RPM (74%) temp=89 grd Celsius
GPU2 5346 RPM (92%) temp=93 grd Celsius
GPU3 3784 RPM (77%) temp=90 grd Celsius
Goal was to bring the RPM's down as GPU3 has 77% at 90 grd Celsius. Both cards are GTX470 but have different BIOS.
But easy use the BIOS of GPU3 without any additional changes did not work as recommended.

Your hints and fora links are welcome.

downloads guru3d NiBiTor 6.04 and other interesting downloads

V8-Xeon is crunching away with temp of all_gpus_88grd_roomtemp_20grd

Looks like my P4 with AGP HD4670 goes slowly to dead again. Sometime after a longer run no VGA output is shown. Then I switch the machine off. If I switch the machine on the graphicadapter shows a red line and says additional voltage cable not connected or missing. This happened twice again. If I switch the power completely off for a longer time the machine starts again. Maybe the new powersupply works not correct. Now after 6 hours outage the machine started again.
Statistic shows pg 1320000 all done with the AGP HD4670 OpenCL application

Tomorrow I will open the case to look up for any cables contact issues...

Yesterday V8-Xeon server get disk error on partition where BOINC is installed. I use a own 2GB partition still for BOINC. I had to reformat it and installed BOINC again.  Bad block is shown in harddisk 0\DR0.
--------------------------- 

Good News
Today 29th february I got the disk repaired by deleting the partition, make new partition, set it as primary, and format it new, so the error is gone.
This was drive D: and on it was still BOINC and some utilities, so the lost parts was small.
After all was done system started normally, I copied BOINC from my USB stick back and all works as before. So we have now again a full operational disk with Vista Ultimate + developer environment.
I feel now better

To test the V8-Xeon Win7 under full load I took part on pg Leap Day Challange and run up to number 23   
So far OK temps ~88-95 grd celsius under full load. Its hot, but I can live with it till summer is comming.
