Prescott trouble

[donnietri]

Does anyone know about Prescott Sudden Death Syndrome?
What should I do if my processor having that problems????? :(
Should I buy a new one or there is a way to solve the problem???

Never heard of SDS for presscotts.
however to much voltage on bad cooling could damage the cpu.
only real option is to "underclock" it. or to rma it.

never heard of prescotts being damaged from voltage, usually the motherboard goes first because of the high stress of power on it, so a mosfet usually blows first.

What exactly is occurring? What are your system specs, mobo, cooling, HDD's, BIOS etc.

The best way to trouble-shoot is to determine exactly when the problem or your system began behaving differently and what has chnagerd or what you've done differently since that moment.

As a simple example lets say your system is randomly re-booting after you went into the BIOS and raised FSB, Vcore but forgot to raise VDIMM. Or perhaps ou raised the FSB but forgot to go into "Advanced Chipset" and loosen up the memory latencies, or set them at SPD.

You need to detail precisely what your system is doing differently or what it's failing to do.

The main problem for Intels is Vcore increase.
Anyway Prescott is a good chip but it is Preshot... :D
Fortunatelly throttling is off download Throttle Watch here (http://www.panopsys.com/Downloads.html) must have freewarre tool for Intels...
I also put small heatsinks on MOSFETs...

My spec..
P4 3,0Ghz Preshot socket 478 w/ TT Pipe 101 + Silverstone FM84XW
Gigabyte 8IPE1000 Pro-G
Twinmos 1A4T 512Mbx2 w/ 2x6"Fan
Gecube 9550 EE 128MB w/ TT Giant 3 Extreme
Maxtor 40 Gb 7200Rpm Pata 133
Seagate 120 Gb 7200.7
TT Pure Power 420W
Bla..bla..bla

I wanna ask OOT,..does anyone know the best bios for my mobo??...I need some help because in the bios there is no cl2 or cl3 in memory setting only cl2,5...I have press Ctrl+F1....

u havnt mentions ur power supply.

That's because of poor installation procedure. Even my 540(not J) @ 3.8GHZ idled at 36c and 53c loaded. I've raised the core voltage up to 1.48 and I didn't have a problem (http://i6.photobucket.com/albums/y218/Nasgul/650SPI.png) at all.

Unlike AMDs (http://www.xtremesystems.org/forums/showthread.php?t=26650&highlight=amd+death) :thumbsup:

"TT Pure Power 420" (Thermaltake)

Here (http://www.giga-byte.com/Download/Download.asp?FileExtName=exe&DownloadPath=/MotherBoard/FileList/BIOS/bios_8ipekpg_f4) is the link to BIOS F4. It states at Gigabyte site this version deals with "Fixed 0F41 CPU can't boot issue"

Below I've copied a page from your manual, which shows divider choices. Depending upon your CPU's FSB the memory multiplies as follows.

FSB(Front Side Bus) frequency =400MHz,
2.66 Memory Frequency = Host clock X 2.66.
Auto Set Memory frequency by DRAM SPD data. (Default v alue)

FSB(Front Side Bus) frequency =533MHz,
2.0 Memory Frequency = Host clock X 2.0.
2.5 Memory Frequency = Host clock X 2.5.
Auto Set Memory frequency by DRAM SPD data. (Default v alue)

FSB(Front Side Bus) frequency =800MHz,
2.0 Memory Frequency = Host clock X 2.0.
1.6 Memory Frequency = Host clock X 1.5.
1.33 Memory Frequency = Host clock X 1.33.
Auto Set Memory frequency by DRAM SPD data. (Default value)

As you can see below each there's a setting for Auto, there should be some way to adjust CAS Latency at the very least? Hopefully the BIOS I've supplied above wil offer more memory settings unfortunately these are usually listed in the revision specifics for each BIOS version.

Your temops look very good to me 36C on air and 45C on air is exactly what Prescott's do on stock cooling if installed correctly and in a well ventilated case. In fact I've had asn FX53 which ran slightly warmer then my P4 550. Of course one reason for this is thermal diode placement in AMD CPU's as compared to Intel. You true core temp, read by the diode which throttles the device is probably about 15C ~ 25C higher then the thermal diode temp monitoring software reads which is strategically located at the core surface nearest the IHS.

F4 bios have installed when I bought the mobo...I think that the voltage of vcore of cpu is drop should be mod...Does anyone know how to mod the mobo that I used??...I've read vdrop mod for ASUS Mobo,but I'm still confused about tools that I used to buy first...

Sorry if I have alot of question..Still newbiee in OCing....
Thanks guys...
