Minneinnstillinger (litt newbie)

[CandyKing]

i en febrilsk jakt på å tyne mer ut av pc'en har turen kommet til minnet.

 

i bios'en kan følgende stilles....

 

CAS latency

RAS to CAS Delay

RAS Precharge

RAS active time

 

noen som har en vettug forklaring på hva dette betyr og hva som kan justeres for hvilken effekt? (litt newbie)

 

har lest i en test at 2-2-2-5 er en agressiv innstilling, som så klart brikkene mine ikke ville ha noe av... per default er mine instillinger 2.5-3-3-6

 

noen som kan komme med en hjelpende forklaring?

 

stats:

no-name pc2100 (1x256,1x512)

asus a7s333 (133/33)

athlon xp1900+ (1,6Ghz)

 

p.s. mistenker at jeg har mer å tjene på "vanlig" overklokking.

fant følgende på http://www.arstechnica.com/tweak/win2k/oth...s/memory-1.html :

 

CAS Latency - CAS latency is a setting which determines the column access time for the RAM in your system. The lower the latency, the faster and more frequently the computer is able to access the RAM for different pieces of information. SDRAM has a standard latency of 3, but most pieces can handle a latency of 2. You can also buy SDRAM spec'ed to run at CAS 2 for a price. RDRAM, on the other hand, has a much higher latency, and it is more greatly affected by a change in latency, so I wouldn't recommend fooling with latency settings if you are using it. Warning: Lowering the latency of your RAM below its specification is a form of overclocking, so be careful. You might also want to run a stability test (timedemo loop or something similar) after lowering the latency to make sure your system is stable.

 

RAS to CAS Delay - This setting determines the amount of time between a row activate command and a read/write command. A lower setting is faster, but take the same precautions with this setting as you would with changing the CAS latency.

 

RAS Precharge Time - This setting determines the number of cycles the RAM requires between DRAM refreshes to accumulate its charge. A lower setting here will speed up the system memory, at the risk of causing instability. Again, be careful to make sure that your system is stable after modifying this setting.

 

Mangler fortsatt info om RAS active time men har litt å ta tak i nå...
