fylon, you just placed a BOMB into bai's pocket. lolz

your upgrade sounds quite "crazy" to me as every cents you pay for the 3850 will not be utilize. maybe half...

if you grap a 6 series or 7 series card, i think the performance will be almost the same like your new 3850. Correct me if i am wrong.

@eclectice, i have a Willy 1.7GHz system at home too but mine is using RDRAM there. Upgrade from FX5500 to ATI3850 is a great move but you will have to suffer the bottleneck from your CPU and RAM as they are pretty slow and have less bandwidth. To complete a task faster,you might definitely need a faster CPU to complete them.

@electice
even with new cpu in i doubt the performance will pump up. if really insist wanna play p4, better grab 2.8ghz+C or E cpu with the mobo. that will serve you better.

till then your sdram cant be use already..... another problem...

electice

instead of a converter for CPU, why not get a S478 mobo

slot in the new AGP card

anyways the cost above actually can get u a whole new rig almost up

@electice, if you are sure that your socket is S478 then is easy. You can just get any proc with 2.4GHz and above. I'm doubt your mobo can support HT.

Get a 2.4GHz proc or above if you can. The bottleneck with VGA can be minimize.

lol

i got S478 Pentium 4 2.4GHZ Northwood HT processor

anyways, last time i read that my X800 already bottleneck the 2.4, i wouldnt want to imagine 3850

ah, i found new purpose on what to do in my old 478 beside than Downloading, watching and storing "X"-Files la. just kidding,

Well last time i check there is no good graphic card for AGP slot this day. And not to mention AMD + ATI new CPU would be cheaper.

Sometime ago i just give up on upgrading my 478.

Intel® 845 Chipset System Architecture
The MCH provides the processor interface, system memory interface, AGP interface, and hub
interface in an 845 chipset desktop platform. The processor interface supports the Pentium 4
processor subset of the Extended Mode of the Scalable Bus Protocol. The MCH supports a single
channel of PC133 SDRAM. The MCH contains advanced power management logic. The 845
chipset platform supports the I/O Controller Hub 2 (ICH2) to provide the features required by a
desktop platform.


Intel® 82801BA I/O Controller Hub 2 (ICH2)
The ICH2 is a highly integrated multifunctional I/O Controller Hub that provides the interface to
the PCI Bus and integrates many of the functions needed in today’s PC platforms. The MCH and
ICH2 communicate over a dedicated hub interface. The 82801BA ICH2 Functions and capabilities
include:
• PCI Rev 2.2 compliant with support for 33 MHz PCI operations
• Supports up to 6 Request/Grant pairs (PCI slots)
• Power management logic support
• Enhanced DMA controller, interrupt controller, and timer functions
• Integrated IDE controller; Ultra ATA/100/66/33
• USB host interface; 2 host controllers and supports 4 USB ports
• Integrated LAN controller
• System Management Bus (SMBus) compatible with most I2C devices; ICH2 has both bus
master and slave capability
• AC ’97 2.1 compliant link for audio and telephony codecs; up to 6 channels (ICH2)
• Low Pin Count (LPC) interface
• FWH Interface (FWH Flash BIOS support)
• Alert on LAN* (AOL and AOL2)

Intel® 82845 MCH Overview
The MCH role in a system is to manage the flow of information between its four interfaces: the
system bus, the memory interface, the AGP port, and the hub interface. The MCH arbitrates
between the four interfaces, when each initiates an operation. While doing so, the MCH supports
data coherency via snooping and performs address translation for access to AGP Aperture
memory. To increase system performance, the MCH incorporates several queues and a write
cache.
The MCH is in a 593 pin FC-BGA package and contains the following functionality:
• Supports single Pentium 4 processor configuration at 400 MHz
• AGTL+ system bus with integrated termination supporting 32-bit system bus addressing
• Up to 3 GB (w/ 512 Mb technology) of PC133 SDRAM
• 1.5 V AGP interface with 4x SBA/data transfer and 2x/4x fast write capability
• 8 bit, 66 MHz 4x hub interface to the ICH2
• Distributed arbitration for highly concurrent operation

System Memory Interface
The MCH directly supports one channel of PC133 SDRAM. The memory interface supports
Single Data Rate (SDR) devices with densities of 64 Mb, 128 Mb, 256 Mb, and 512 Mb
technology. The memory interface also supports variable page sizes of 2 KB, 4 KB, 8 KB, and
16 KB. Page size is individually selected for every row and a maximum of 8 pages per DIMM may
be opened simultaneously.
The MCH supports a maximum of 3 double-sided DIMMs (6 rows populated) with unbuffered
PC133 (with or without ECC) Note that in mixed mode, populating ECC and Non-ECC memories
simultaneously is not supported.

Memory Capacity

Technology SDR (PC133) Maximum (double-density x 3 SIMM slots)
64 Mb                             384 MB
128 Mb                           768 MB
256 Mb                           1.5 GB
512 Mb                           3 GB

@eclectice,you can get any Northwood with the best speed. Your mobo chipset doesn't support on HT.It's better to get the 400/533 bus speed proc. Afraid some HT proc can't work properly on your mobo.

i thought bios can disable HT ?

then shouldnt be a problem anymore, even with HT proc

No,the 845 chipset doesn't support HT proc.

@eclectice,hope you can get the 2.4GHz or 2.6GHz in garage sales.Good luck.

Yes, I will do my best to get the best Pentium 4 CPU for this S81M mobo.

I know I can find the thermal paste, but where can I get the thermal sticker for the heatsink?
