I have a ECS P4S5A/DX+ board with a P4 2.0 Ghz, and 512 Mb of ram. I've installed a program that came with the configuration disk, called SiS System Hardware Monitor, and made it run. Now it keep's telling me some warnings. They are: 1 - 12V is too low! ( it shows 5.66 to 5.72 V) The limits of warning are set to Lower 10.8V and Upper 13.2V 2 - 5V is too low! (it shows an average of 4.02V) The limits of warning are set to Lower 4.5V and Upper 5.5V 3 - I/O Voltage is too low! (it shows an average of 3.10V) The limits of warning are set to Lower 3.2V and Upper 3.8V 4 - Core Voltage is good! Running at 2.82V I want your help to know if this is bad for my system or by the contrary it makes no harm. I'm running W XP Pro with SP1. Thank for any help.

Hey jmcv! <img src="i/expressions/face-icon-small-smile.gif" border="0"> <img src="i/expressions/face-icon-small-shocked.gif" border="0"> first thing I would do if I were you is, go into your BIOS and check the voltages... It's possible that the program is just going crazy. If the BIOS confirms what the monitoring program says, then try changing the PSU. If you have the same problems, then obviously it's the mobo. <img src="i/expressions/face-icon-small-sad.gif" border="0"> Yes this is bad for your system and something may burn out, you should definitely get that checked out soon!

Hi Colin! Thanks for your help! I've done what you told me to. I went to the BIOS and in the Hardware Monitor i found Vcore 1.472V Vcc2.5V/Vcc3.3V 2.448V Vcc3.3V 3.104V Vcc 4.945V +12V 12.416V SB3.3V 3.264V -12V -11.803V SB5V 4.865V VBAT 3.264V System fan 0rpm CPU Fan Speed 4300rpm System Temp 29ºC/84ºF CPU Temp 38ºC/100ºF I also runned the Sandra 2003, and in the report for the MB it gave me this: Computer System Manufacturer : ECS Model : P4S5A/DX+ Version : 1.0 Serial Number : 00000000 Unique ID : 00000000-00000000-00000000-00000000 System Chassis Manufacturer : ECS Case Type : Desktop Can be locked : No Version : 1.0 Serial Number : 00000000 Asset Tag : 0123ABC System Mainboard Manufacturer : ECS MP Support : No Model : P4S5A/DX+ Version : 1.0 Serial Number : 00000000 BIOS ID : 62-0822-001131-00101111-040201-SiS64X Memory Controller Error Detection Method : 32-bit ECC Error Correction Capability : 1-bit Supported/Current Memory Interleave : 1-way / 1-way Number of Memory Slots : 4 Maximum Installable Memory : 512MB Maximum Module Size : 128MB Supported STD/FPM/(B)EDO Speeds : 70ns, 60ns Supported Memory Types : STD, FPM, EDO, Parity, ECC, SIMM Supported Memory Voltages : 3.3V Physical/BIOS Memory Banks ROW-0 : Empty ROW-1 (RASL-6 RASL-11) : 512MB DIMM SDRAM double-bank ROW-2 : Empty ROW-3 : Empty System Chipset Model : Silicon Integrated Systems (SiS) SiS645DX CPU to PCI Bridge Bus(es) : ISA AGP USB SMBus/i2c Front Side Bus Speed : 4x 100MHz (400MHz data rate) Max FSB Speed / Max Memory Speed : 4x 133MHz / 2x 166MHz In Order Queue Depth : 8 req(s) Priority Master Queue Depth : 7 req(s) Chipset Hub Interface Type : MUTOL Width : 16-bit Full Duplex : No Multiplier : 1x Logical/Chipset Memory Banks Bank 1 Setting : 512MB DDR-SDRAM 8-1-1-1R 6-1-1-1W 2.5-3-3CL Refresh Rate : 7.80µs Power Down Mode : No Fixed Hole Present : No Environment Monitor 1 Model : ITE IT8705/12 ISA Mainboard Specific Support : No Temperature Sensor(s) Board Temperature : 76.0°C / 168.8°F CPU Temperature : 29.0°C / 84.2°F Power / Aux Temperature : 36.0°C / 96.8°F Cooling Device(s) Auto Fan Speed Control : No CPU Fan Speed : 4116rpm Voltage Sensor(s) CPU Core Voltage : 1.47V Aux Voltage : 2.45V +3.3V Voltage : 3.06V +5V Voltage : 5.05V +12V Voltage : 11.92V -12V Voltage : -0.27V -5V Voltage : -5.46V Standby Voltage : 4.87V Battery Voltage : 2.03V AGP Bus Version : 2.00 Current Data Transfer Rate : 4x Side Band Enabled : Yes Fast-Writes Enabled : No Aperture Size : 64MB LPC Hub Controller 1 Model : Silicon Integrated Systems (SiS) SiS85C503/5513 PCI to ISA Bridge (LPC Bridge) ACPI PM Enabled : Yes Random Number Generator Enabled : No Speed : 7MHz USB Controller 1 Model : Silicon Integrated Systems (SiS) SiS5597/8 Universal Serial Bus Controller Version : 1.00 OHCI Interface : Yes Channels : 2 Legacy Emulation Enabled : No USB Controller 2 Model : Silicon Integrated Systems (SiS) SiS5597/8 Universal Serial Bus Controller Version : 1.00 OHCI Interface : Yes Channels : 2 Legacy Emulation Enabled : No USB Controller 3 Model : Silicon Integrated Systems (SiS) SiS5597/8 Universal Serial Bus Controller Version : 1.00 OHCI Interface : Yes Channels : 2 Legacy Emulation Enabled : No USB Controller 4 Model : Silicon Integrated Systems (SiS) Unknown (7002) Version : 2.00 Spec : 1.00 EHCI Interface : Yes Channels : 6 Legacy Emulation Enabled : No System SMBus Controller 1 Model : SiS 5595 Internal SMBus Expansion Slot(s) PCI1 (1h) : PCI 32-bit 3.3V Shared PME FullLength Available (Silicon Integrated Systems (SiS) 5591/2 Virtual PCI to PCI Bridge) PCI2 (2h) : PCI 32-bit 3.3V Shared PME FullLength Available (Silicon Integrated Systems (SiS) SiS85C503/5513 PCI to ISA Bridge (LPC Bridge)) PCI3 (3h) : PCI 32-bit 3.3V Shared PME FullLength InUse (Silicon Integrated Systems (SiS) SiS5597/8 Universal Serial Bus Controller) PCI4 (4h) : PCI 32-bit 3.3V Shared PME FullLength Available PCI5 (5h) : PCI 32-bit 3.3V Shared PME FullLength InUse ISA1 (6h) : ISA 16-bit 3.3V Shared PME FullLength ISA2 (7h) : ISA 16-bit 3.3V Shared PME FullLength Port Connector(s) USB - Def : SSA SCSI - Mini Centronics / DB25 pin male Performance Tips Warning 2533 : Disabled host controllers are present.

I'm sorry for all the work i'm giving you, but i think you are an expert in PC's, and i've already e-mailed the support team off the manufactor (ECS) and they never gaved me an answer. I found that this site was very helpfull for getting to know a little bit more about my PC, and taking all resources that i can, of it! I'm from Portugal, and don't mind any spelling mistakes. Thanks.

jmcv, don't worry about it man! <img src="i/expressions/face-icon-small-happy.gif" border="0"> We're all newbies to computers at one point! <img src="i/expressions/face-icon-small-smile.gif" border="0"> << I went to the BIOS and in the Hardware Monitor i found Vcore 1.472V Vcc2.5V/Vcc3.3V 2.448V Vcc3.3V 3.104V Vcc 4.945V +12V 12.416V SB3.3V 3.264V -12V -11.803V SB5V 4.865V VBAT 3.264V System fan 0rpm CPU Fan Speed 4300rpm System Temp 29ºC/84ºF CPU Temp 38ºC/100ºF >> Looking at the voltages in your BIOS, I would have to say everything looks ok... Your 12V and 5V lines look just fine, a tad low but within tolerances... I'm guessing Sandra and the SiS hardware monitor is reading your motherboard wrong.

Hi Colin! I think that you're right! My mobo never gave me any problem, neither my PC had crashed! I don't understand how a software, that was made by the mobo manufacturers, could give us wrong values. Neither how Sandra is confused with the situation! I've runned another sw, the SpeedFan 4.05, and it showed the same values (aproximatedly) that i send you. Also, the mobo temperature was 76ºC! I opened the Pc and it seems that everything is connected in the right places, and there wasn't any strange smell, neither a hot sense. Everything was cool. Now another question! My mobo supports 333mhz ddram, and my ram is also 333mhz. My Cpu/dram speed is set at 100/100mhz, and the bios give me some options on changing it. Do you think that i can have a improvement in performance by changing that relation? The cpu core voltage can't be changed, and the cpu ratio is locked. What are my chances? I don't want to make something very risky, because it is running quite fast, and i'm not interested in burning any pieces! <img src="i/expressions/face-icon-small-cool.gif" border="0">

jmcv as long as your computer is running fine don't worry about it! <img src="i/expressions/face-icon-small-happy.gif" border="0"> If your processor is 100 MHz based, I'm not sure if you can set your memory to run at 333 MHz mode. I'm not sure haven't used an SiS 645DX in a long time! If there is that option though, definitely use it!!! P4's are all bandwidth limited and raising the memory speed gives the P4 more bandwidth which will give you better performance! Don't worry, running your memory at 333 MHz is not overclocking so you're not risking burning out anything! <img src="i/expressions/face-icon-small-happy.gif" border="0">
