cmos바이오스를 7월 3일짜로 바꿔봤습니다.
8월 8일자 있으신분??
백업이라도 하셔서 주세요.
지금 7월 3일는 ddr 전압이 3개밖에 안됨.
다들 아시다 시피 (디폴트, 2.55V, 2.60V, 2.70V)
8월8일자는 4개가 되는거 같던데.
제껀 아직 2.8볼트가 지원이 안되네요..
전에 쓰던게 아마 6월 6일자인가?
그거보다 메모리 옵션이 2-3개 추가 됬네요.
전에꺼도 CPU RATIO가 14배 까지 지원됬는데.
여기 나와있는 문서상으로 14배가 지원된다고 나왔네요?
AK31S907
Notes
-----
Use this BIOS at your own risk!!! Flashing the wrong performance BIOS on
the wrong PCB version will cause total boot failure.
This performance BIOS is intended for advanced/power user use only,
since this BIOS is specially tuned and for use in conjunction with
"qualified" hardware devices which meets the performance BIOS requirement.
If after Bios flash, the system does not boot or give blank screen
please clear CMOS, try other DDR and H/W devices otherwise please take
the original non-performance BIOS to an EEPROM programmer and have the
Bios Firmware reprogrammed. If for some reason the system becomes unstable,
please go into bios setup > Advanced Chipset Features > DRAM Clock/Drive
Control and set...
* SDRAM Cycle Length -> 2.5
* Bank Interleave -> Disabled
* DRAM Command Rate -> 2T Command
The user can fine-tune the above DDR SDRAM options in Bios Setup till
the system is stable and give optimal performance output possible.
Bios flash instructions
-------------------------
1. Make a bootable floppy disk
http://www.spacewalker.com/english/support/faq/top10QA/dosboot.htm
2. Extract the ZIP file into a bootable floppy disk
3. Restart, boot from floppy a: into DOS prompt
4. Type awdflash AK31S907.bin /cc/cd/cp/py/sn/r
this flash command will clear CMOS data and restart system after BIOS
flash programming completed. After system restarts, please load optimized
setting in BIOS setup.
Or just type awdflash AK31S907.bin in DOS prompt, restart system and
load Optimized Setting in Bios Setup Menu.
Bios History
------------
AK31S907 07/03/2001 checksum : 752E
1. Added Menu "Precharge to Active"
command period
2. Added Menu "Active to Precharge"
command period
3. Added Menu "Active to CMD"
4. support CPU ratio x14.0 (?? 이해가 안됨, 전에꺼도 지원하는데)
cmos bios utility에서
Advanced Chipset Features
->
DRAM clock/Drive Control에서
*Precharge to Active
(trp=2T , 3T)
여기서 trp가 몬가요?
transfer rate period인가요?
하도 영어를 안쓰니깐 스팰링도 틀린거 같네요.
*Active to Precharge
(tras = 5T, 6T)
tras는 또 뭐죠?
하여튼 낮은게 좋은거 아닌가요?
그리고 마지막
*Active to CMD
(2T , 3T)
CMD->COMMAND인가요?
아시는분 답변좀.
그렇게 3가지가 바꿘거 같네요.
7월 3일짜를 기준으로해서
