I have the Gigabyte 8S661 FXMP RZ mother board . my processors only showing one processor in task manager . yesterday i had two ( dual processor )What can i do ?? regards Peter

List of supported CPUs:
Gigabyte 7VM333M RZ processor support and specifications

Specifications for fastest supported CPU:
AMD Athlon XP 3000 333FSB CPU

hi.there...

i read from your information and picture about your motherboard type..i think yours is not under warranty from factory anymore (GIGABYTE)

for additional information your mainboard (MB) is using old type of intel chip set (Intel 865 series) and only support intel processor type Pentium 4 with 478 pin with 533 MHz bus processor..

talking about warranty from factory GIGABYTE only give 3 years warranty only for MB with minimum chipset intel ICH 7 and up..that's mean MB must be support processor minimum 775 pin and 1155 pin or support intel Pentium D,Dual Core,Core2Duo or Core i series...

hope this is can help to solve your problem..

The problem is in the processor or in the board to check first change the processor sutable for the socket and switchon the computer still the computer doesnt work check the secondery power supply thats four pin from the smps to the motherboard check all the FET and the capacitor in the powersupply also the 32khz crystel and the 14.182khz crystel and the clock ic

only socket 775 (also known as socket a) are able to be used so thats the duron sempron and athlon xp line.

support the Intel's Core™ 2 Duo mobile series, as well as Core™ Duo LV / ULV, Core™ Solo ULV and Celeron M processors

Good luck ! if your problem solved don't forget to vote

In the small chart in the middle where it states, Overview, Awards, BIOS, Comparison Sheet, CPU Support List Driver, FAQ, Manual, and News, click on > Driver.

(AMD Sempron 2400+
That fits in a Socket A processor socket. Socket A is also known as Socket 462.
Click on Manual for the motherboard manual)

Yes for the Intel Pentium 4/2.4GHz/533FSB processor. (Socket 478)

(Scroll through. What sSpec number is on top of the processor's case? {You are following Anti-Static Precautions, correct? }

Won't support better than a Prescott Core Pentium 4. (Next chart down)

The Gigabyte GA-8I ((Supports 400MHz or 533MHz FSB)

NO to the Ram Memory.
The Gigabyte GA-8I845GVM-RZ supports DDR Sdram at 333Mhz. (PC2700)
IMHO it will not support DDR Sdram at 400MHz. (PC3200)

My reasoning is this;

Ram Memory typically operates at half of the FSB frequency rate of the Processor.

Processor FSB > MAXIMUM frequency rate is 533MegaHertz for the GA-8I845GVM-RZ
Ram memory at 333MHz is doable.
Not 400MHz.

No, you won't be able to overclock, and bring the FSB of the Processor high enough for PC3200 Ram Memory.
(The rest of the motherboard wouldn't work anyway if you did. PCI Express bus, PCI bus, etc., would not match)

Try to remove the motherboard (BIOS) battery in order to return to it's manufacturer's default settings....

You might have damaged the CPU/ motherboard during the process of overclocking.

Check your CPU on other compatible mobo.

Check your mobo documentation properly & set the jumpers rightly. If that doesn't help, you will have to replace the mobo.
