Well it depends on what kind of operating system and applications you are using. When you're a gamer you must have a 2gb and above memory. For a Windows Xp user and for home use, 1 Gb is enough.

Ibm fru pn 49p1599

The p/n (FRU 49P1599) is a Gigabyte motherboard, their p/n GA-G8IGMIU Rev 1.1 It seems to be a socket 478 type with FSB 400 or 533MHz, Intel 845G chipset, and DDR1 memory. In the downloads section of Gigabyte's website it is not present, probably because it so old it has been removed. In this section there is the opportunity to get the manual for a motherboard and the CPU support list, amongst other downloads. A similar m/b, the G8IG model supports ONLY older Williamette and Northwood type P4 CPUs, not the (slightly) newer Prescott ones. I suspect that your CPU is not working because it is a Prescott type (or it is just broken). To check what process your CPU was made by use the program Speccy, or take a magnifying glass and examine your processor (having carefully cleaned it up) for the S-code, RK or BK number, and look it up on Intel website (ARK) or in CPU-World.

AND you should contact Gigabyte technical support (you have to go through the register rigmarole) to see they are able to answer questions you may have, get the manual and the CPU support list.

I want to upgrade my CPU capacity from 1.2 GHZ and want to know my motherboard so much support??? my motherboard is GA-8IDX (845 chipset)

If you go to, you can see all of the different processors that are compatible with your motherboard:

The ones highlighted in pink are not supported for your motherboard, the ones highlighted in orange may or may not be, and all the ones in white are compatible with your motherboard. It looks like you have several high-end options, up to 2.8 GHz.

Gigabyte ga-81915 pmd motherboard/precott 3.6 cpu/upgrade cpu?

the best and cheapest up grade is RAM.
Make sure you have all the memory your machine can handle.
A quick look say it can handle Core™ 2 Extreme QX9770(3.2GHz,12 MB)
And it has a PCI-express slot so you have a big chiose of video cards.Are you using the machine for gaming?

Upgrading CPU

Probably nothing. If your system works, I would not concern myself greatly with this small detail. The system indicates a 3.4 GHz cpu installed. Your software may misidentify some of the features of your Prescott.

Processor compatibility

looks like you limited to the p4 Prescott, this is a p4 list of the cpu support from asus. I also looked at their bios update page and found no bios improvement. if you can move to the 775 platform ,you can move from p4. otherwise, the p4's are still  good . I had the cpu that is the 2nd one down. 3.2ghz oc'd to 3.8ghz full time with a max of 4.0ghz on air[775 platform] quad-pumped gave me a 1001.3mhz FSB

Gigabyte GA-81EXW motherboard needs ram

If you plan on gaming then go for the higher priced and yes more ram will help in a gaming situation but if your just surfing and writing emails then no you don't need them,It's the timings that make ram better or not,all motherboards will do ok with cheaper ram but make sure you have the correct ram and install it in 1 and 3 or 2 and 4 they are usually colored the same

Gigabyte GA-81EXW memory chips

Any 184-pin ddr ram should work on this. You can actually use pc3200 (ddr 400) ram as well. Pc2700 ram is ddr333, and a higher speed ddr ram like pc3200 will work just as well if not better than pc2700, it will simply go down to the speed that the processor requests the ram run at. It's all backwards compatible, faster ram can run slower if the computer needs it to run at the slower speed. Depending on the price you can find as long as you get 184 pin ddr ram either pc2700 or pc3200 with work fine with your motherboard. Peter
