| Info about the new chips coming shortly? Boe 05:16:27 |
| | Hello,
A link was sent about the new AMD chips coming out next month and I'm very
curious. Has Tom's or anyone done any reviews of the x2 5000 AM2 or any of
the other chips. I realize they won't hit the street for another month but
often reviews are available in advance.
Thanks

| RAID controllers - BIOS conflict - pls help Nobody@Nowhere.Net 10:26:02 |
| | "I have a MSI Master2-FAR (VIA K8T800 chipset) dual Opteron 242 system
with boot drive on built-in VIA SATA RAID controller. I installed
Promise FastTrak SX4100 (SATA RAID controller - 32 bit PCI, hardware
RAID 5 engine) and 3 WD 250GB drives. When I configured the drives as
RAID 5, I received the message "PCI ROM space is NOT enough", and then
the board was unable to load VIA RAID controller to boot off it.
However, when I connected the same drive to a free port on SX4100
instead of onboard SATA, the system booted just fine (Win2k), and both
RAID controllers were in device manager. However this solution is not
acceptable because my intent was to have bootable RAID1 on VIA and
RAID5 on SX4100 reserved for data. Please let me know how to ensure
that Promise SX4100 BIOS loads AFTER VIA SATA BIOS, so that my old
boot configuration could be restored."
The msg above is a copy of what I sent to both MSI and Promise
support. So far no reply from any of them.
Google/Yahoo have a couple of hits on "PCI ROM space is NOT enough",
but only complaints and no solutions. Seems like Promise grabs so
much memory out of whatever is allocated for BIOS that no other device
can be loaded after that. Funny though that as long as no logical
drive is defined, everything goes fine and VIA SATA is recognized on
boot. Could not find anything in either SX4100 setup or mobo BIOS
setup that would help. Could it be that VIA SATA sucks? Would
another Promise/sil RAID controller solve the issue? All I want is
RAID1 as system drive and RAID5 as data drive. I guess I could go
SCSI for boot drive in worst case, but there is no guarantee that SCSI
BIOS would not conflict with Promise BIOS, either.
Any and all help will be greatly appreciated.
TIA

| HTX Coprocessor for AMD The little lost angel 08:16:49 |
| | Just wondering, since HT can be used as a bus the way PCI-Express can,
is there any reason why a coprocessor on a HT connection shoud not/
cannot be done in the way of a slot in card? Wouldn't this take up
less board real estate and allow much more flexible designs since the
card can be much bigger than a predefined socket size?

//---------------- Tips
If BIOS <7.0 the bios has to be updated to v7.0. (FD is required)
Old BIOS can support one dual core CPU so, set in one Opteron280 in
socket0 update BIOS to v7.0 then put second CPU in)
Populate 4 memory DIMMs A1B1 A3B3
The RAID-0 should be set on NVIDIA RAID (FD is required)
With memory recommended above the simple over-clocking below does not
require any special voltage/timing tuning:
- The memory latency can be set to CAS 2.5 (2.5-3-3-8-1) (BIOS
settings)
- The CPU speed can be set to 215 (provides free upgrade to Opteron
285) (BIOS settings)
- Disable all spread spectrum options (BIOS settings)
- Set only basic ECC options (for all banks) (BIOS settings)
To speed up booting:
- Switch off all unused IDE
- Switch off Silicon RAID controller (jumper on MB)
The ASUS web does not have the latest drivers for NVIDIA chipset
I would recommend take the latest from TYAN website
http://www.tyan.com/support/html/drivers_support.html
* nVidia Chipset
* SATA RAID for nVidia nForce chipsets
The SATA RAID-0 has to be saved on FD in order to install Windows on
RAID ("press F6" procedure)
Drivers can be taken directly from NVIDIA website; however there is
some confusion what chipset package has to be used for k8n-dl.
Regards,
Stefan

| K8L details emerge Yousuf Khan 12:26:59 |
| | Lessee what the highlights are:
-shared L3 cache
-quad-core
-independent voltage regulation of the cores as well as the northbridge
-48-bit addressing, 1GB page sizes
-official coprocessor support through an HTX connector.
-very flexible DDR2/DDR3/FBDIMM support
-memory mirroring
-data poisoning
-HT retry
-doubled FP units
-prefetch tweaks
AMD shows off details of K8L
"Next is memory. The new core will support 48-bit addressing and 1GB
pages. Cray and SGI will be very happy with this, until they hit that
memory wall again. There is also official co-processor support, strongly
hinted to be on a HTX card. The key here will be the platform is aware
of them vs having to hack them in."

| The multi-core scalability issue with BIOS v1008 Guest 08:53:33 |
| | SBJ: The multi-core scalability issue with BIOS v1008:
After update BIOS from v.1007 to v.1008, the speed of heavily threaded
applications, gets slower around ~ 1.48 times. All 4 cores are loaded
only 55-70% comparatively to 90% with BIOS v1007. After flash back to
BIOS v.1007 the speed gets normal as it was. This test has been
performed extensively multiple times; the result is the same; v.1008
kills the multi-core scalability to the ground.

Hey, little lost angel, welcome back. Where ya been?
It's good to see you and the other guys from s.e.b/s.e.d. too!
I've been busy with study and work. Work's mostly design/programming &
marketing leaving very little time to pursuit side hobbies like
electronics. For a while I dropped off the radar on Usenet totally
having had to spend more time tracking local web forums for marketing
purposes and only been back in csiphc for a few months.
Hopefully I'll have some time to drop into seb/sed to bug you guys
with more innate noobish ee questions on some stuff I've been
wondering about PPp

| Need for speed. Russel Sprout 21:53:52 |
| | Well not extreme speed, but a little better than I have now - AMD Athlon XP
2200+.
I am not interested in gaming or video/image manipulation, just pure umber
crunching. I'm working on a project where a program is run several times,
currently each run takes around 10 mins, CPU is running at 100%, but its not
using much RAM (PC2100) and disk activity seems to be low. I'd like to cut
this to 2 mins or below. Specifically I'm running degrib with the -prb
swich, if that means anything to anyone. It decodes compressed weather model
data in GRIB2 format, files are typically big, 32Mb.
Any sugestions, price is a consideration, but I'd like the best bang for
bucks. The program is 32 bit, but I think there may be a 64 bit version and
it may also be optimised for multiple proccesers.
TIA

| Beware "free" USB Flash drives George Macdonald 06:10:18 |
| | Hmm, so I got this 128MB USB 2.0 flash drive as a freeby - came as a "combo
special" with an Athlon64 I bought from NewEgg - it's transparent green and
has a NewEgg and AMD logo on it. I used it to bring a bunch of files home
from the office to work on and first indication I got that anything was
awry was a WinZip error saying this .ZIP is a continuation of a preceding
volume in a multi-volume set... which I knew it wasn't.
WinXP's Error Check doesn't show errors or give a summary (yeah I forgot
about Event Log at first) but CHKDSK /R gave a whole bunch of msgs about
bad clusters. I tried writing a few large .ZIPs and they seemed OK then I
tried a largish (200 files or so) directory structure and it was really a
mess with CHKDSK /R. Only then did I look in the Event Log and find it was
polluted with Bad Block msgs: "The device, \Device\Harddisk1\D, has a bad
block"... usual M$ informative stuff!<shrug>
Funny I'd always thought those things would either work or not at all but I
guess they're just as bad as magnetic media. The thing is I hadn't used
this thing much so I'm not sure if it was bad to start with or not...
though I suspect so. The annoying thing is that (full) Format does not
complain and the Error Checking/Check Now/"Scan for and attempt recovery of
bad sectors" and CHKDSK /R only find bad blocks if there are files stored
in the bad areas.
I guess I'l lbe running CHKDSK /R on newly created files on flash drives
for a while now.

| The Theory Would Indicate Increased Performance; BUT! Guest 01:00:06 |
| | Ok, I want to believe there is, or would be, and increase in
performance with the AMD dual core; but I've yet to experience it.
I've tried:
Windows XP SP2
Windows XP 64
Vista 63 (latest build)
And I don't see it!
Do I regret the decision to go AMD dual core. Well not exactly, but I
seriously doubt those claims that the future will be brighter.
What do I need four, eight or sixteen cores to see a real increase
from any of Microsoft's offerings, or is it time to switch to...
Just some thoughts.

| MTBF question Dp 20:03:05 |
| | Slightly off topic, but since there was a long discussion on this subject
under the heading "Dual Core Comparison," I thought I'd ask here first.
The MTBF number is good only if manufacturers are getting good reports from
the field about their products, right?
If my drive fails and it's out of warranty (or perhaps it's in warranty and
I can't find the paperwork to file the warranty claim) then I'm likely to
just get what data I can off the drive, destroy it and/or throw it away. As
a result, the manufacturer never knows the lifetime of my drive (or
thousands, if not millions, of others).
Is MTBF just a number derived from lab testing? Obviously, it doesn't
include those people who've had equipment failures and never notified the
equipment manufacturer of the failure. How reliable then is "mean" under
those circumstances?

| K7s5a flashing problem Rubbie 17:19:22 |
| | Now I know this might not be directly related to this group, still i'm gonna
try my luck in here.
I got a MB from a friend of mine, ECS K7s5a (ver 3.1). I installed an amd
xp2200+. Booted the system and noticed that the cpu is running @ 1350 mhz.
So i tried to flash the MB so it would recognize the cpu correctly. I used
the tools provided by ECS. But when I tried to flash the MB, the programm
told me the MB doesn't support flashing.
Does anyone have a solution to this? The BIOS used is Amibios. I also tried
their flash utility, and it tells me the same thing: MB does not support
flashing.
What to do?
Any help is appreciated,
Regards Rubbie

| CPU makes high-pitched noise Anonymous_c 07:05:52 |
| | I have a VIA C3 533MHz fanless CPU. I'm using it as a server. However,
when the CPU starts to do something, it emits a high-pitched noise.
It's not loud, but noticeable. I can handle it -- it's no louder than
my PC fans. But I'm curious as to why it's happening, and if I can stop
it.
I've ruled out everything else but the CPU/mobo. I've unplugged the
harddrive, but it's still making the noise. The CPU (obviously) has no
fans, and neither does the PC. It's not the PSU, as I've used it before
on a much beefier system (this one uses about 15W total) with no
problems.
If the CPU is idling, however, there is no noise.
Anyone have a clue?

| PC industry will die because of Rambus win Ar Q 22:59:36 |
| | "Rambus (RMBS:Nasdaq - commentary - research - Cramer's Take) won a major
court victory Monday, when a jury found that South Korea's Hynix
Semiconductor infringed on the company's patents.
A federal court jury in San Jose, Calif., found that Hynix, the world's No.
2 computer memory maker, infringed on all 10 patent claims at issue, and
awarded Rambus $307 million. At issue were various flavors of memory
interfaces, including DDR, DDR2 and SDRAM, used in personal computers and
servers."
So Court ruled that Rambus did invent SDRAM and its derivatives. DDR beat
RDRAM but Rambus got the last laught. Also, does this mean that we are back
to late 90's when personal computer manufactures had to spend $500 on memory
system since Rambus priced its RDRAM stick $250 each (you must use 2
together) and the price got higher every month during RDRAM's 2 year
domination period?
