Hi, I have recently assembled a new computer for my daughter based on
SYNTAX SV266A Mobo. I would like to ask some other users of this MoBo
if they can run it at 133MHz ? My machine is crushing consistently. I
have Win XP Pro with SP1 so it reboots automatically. When I disable
automatic reboot it sometimes report some errors like "…
IRQL_NOT_LESS_OR_EQUAL …" "… STOP : 0 x 00000000A ( 0 x F9E4FFC4, 0 x
000000002, 0 x 00000001, 0 x 804EC1B9) …" , but sometimes there is no
message or it is different.
I downloaded and flashed the BIOS from Syntax.usa.com ( but I think it
is the same BIOS as on the CD supplied with MoBo ) Did not help.
I changed the jumper into 100MHz and so far I did not have a single
crash/reboot.
In my opinion this motherboard my have a problem with running at
133MHz.
Has anyone have running at 133MHz ? If yeas what is your other
hardware ?
I have :
Syntax SV266A ( VIA KT266A and VT8235 chipset )
Athlon 2200+ ( suppose to run at 1.8GHz )
Leadtek WinFast 32MB AGP ( x 4 ) graphic card
SDRAM 133MHz 3.3V ( 2 modules x 128MB = 256MB )
old Fujitsu 4.1Gb ATA 100 drive connect with 80m pin cable on primary
IDE
old Samsung x 48 MAX CD-Rom drive connected on secondary IDE
case PSU 300W.

Please share your experience.
Thanks, Mark

having any problem running the FSB at 166MHz (other than there's no 5 pci

Thanks for your inputs. This was my suspicion, too. SDRAM I use came
from my old machine and it used to work OK. Do you know how to slow
the memory ? I can't see this option in the BIOS settings. Can I run
CPU and RAM asynchronously, at different speeds ? The only think I
did, is set MoBo's jumper into 100MHz.
Thanks again, Mark

Hi,
Thanks again. There is something about that on page 34, but I am not
quite sure what values should I put instead of "SPD". Can you guide
me into it, please. I have run a test with MemTest-86. At 100MHz ( set
by jumper ) the was no errors. But when I set the speed into 133MHZ it
shows plenty of errors !
Any comment on this, please.
Regards, Mark

I don't have your board and the manual doesn't list the options. Instead
of SPD, choose 100MHz if that option is there. Cas should be 3. If you
will list the bios ram selections and options for each, I'll give you the
settings you should try.

Hi, thanks again for your support.
Here are my BIOS options :
In Advances Chipset Features :
DRAM Clock/Drive Control :
DRAM Clock : [ by SPD ] or [ 133 ]
DRAM Timing : [ by SPD ] or [ Manual ]
DRAM CAS Latency [ 2 ] or [ 3 ]
Bank Interleave : [ disabled ] or [ 2 Bank ]
Active to Procharge ( Trp ) : [ 6T ] or [ 5T ]
Procharge to Active ( Trp ) : [ 2T ] or [ 3T ]
Active to CMD ( Trp ) : [ 2T ] or [ 3T ]
DRAM Burst Length : [ 4 ] or [ 8 ]
DRAM Queue Depth : 4 Level, 2 level, 3 level

Any suggestion on above, please ?

If you set the FSB to 100, is there a 100 option here? If so use it.
Otherwise try both.

Try Nanual with below settings and by SPD.

3

Disabled

6T

3T

3T

Try both, or use default.

Use default or try all.

It's odd there's no 100MHz dram clock setting. Good luck. Might try a
Gigabyte forum for a solution. Someone, somewhere has had this board
and has the answer. Then again, it may be that old ram isn't PC133 and the
board won't run slower than that. Only option would be to replace the ram.

Hi,
Yesterday I swapped PSU from my other machine. The same thing. The
system is very unstable when jumper is set at 133MHz. Automatic
reboots, freezes…ect. I tried your setting. Everything works OK when
board is set to 100 MHz by the jumper. It cannot be RAM, because I
tried 4 different modules. I am giving it up. I spoke to my supplier.
He said, he can replace or re-found, following his own test. What a
hassle for 25 GBP ! I have read some messages about other people quite
happy with this board, but for me it is just bad luck.
Thank you very much for your support.

I'm using PC133 Mhz memory from an old BX board with no problems. System is
rock solid.
Cpu and bus at 133Mhz.

I assume you pulled off all those jumpers to use sdram.

To be honest given the cost and hassel you are having I'd inclined to stick
some pc2100 ddram in it.
A warning: People on ebuyer.com have had trouble using cheap ddram on this
board so Crucial or similar may be the way to go.

I'm on bios 2003-0917. The main change for this seemed to be that it
correctly recognised my amd duron 1.6.
Have you pulled the latest 4in1 drivers down from Via Arena?

A 4.1Gb disk running xp must be tight. It will probably be the main bottle
neck on the system.
