Abit KV8-MAX3 and 3 CMX1024-3200PT = DDR200?

Hi,

I really am not a knowledgable person about RAM compatibility and timing, but i have a Abit KV8-MAX3 mobo and due to some high memory intensive apps decided to upgrade it to 3GB which it should support.

 

The only way this system will post and run stable is if i let the RAM completely auto detect (spd and anything manual i have tried wont boot / unstable). When it auto detects, it runs at DDR200 (it should be DDR400 as the mobo and ram support it i think).

 

Here are the memory settings i have available to me in the BIOS:

 

- DDR Voltage (currently at 2.8v after reading around here a bit but doesnt seem to help)

- DRAM Clock (2, 2.5, or 3)

- Cas Latency Time

- Row Cycle Time

- Row Refresh Cycle Time

- RAS# to CAS# Delay

- RAS# to RAS# Delay

- Min. RAS# Active Time

- RAS# Precharge Time

- Write Recovery Time

- Write to Read Delay

- Read to Write Delay

 

The RAM is rated 3-3-3-8 but aside from the first number i don't know exactly which of these the others correspond to.

 

Any help is extremely appreciated.

 

Thanks!

Ok - after reading around here a bit it seems memory upgrades are not as straightforward as they seem - even though i need 3gb memory for the apps i am running, would i be better off with only 2 matched 1gb sticks with the board i have so that it will run ddr400?

 

And what is the performance hit of 3gb @ ddr200 vs 2gb @ ddr400? Am i losing a lot?

 

Thanks,

Fred

OK RAM GUY,

 

I got TWINX2048-3200PT because that was the only thing the store had, from the RAM setttings in my first post, could you tell me what to set my settings to?

 

This is what I have right now:

 

- DDR Voltage = 2.80 V

- DRAM Clock = DDR400

- Cas Latency Time = 3.0

- Row Cycle Time = Auto

- Row Refresh Cycle Time = Auto

- RAS# to CAS# Delay = 3 Clocks

- RAS# to RAS# Delay = Auto

- Min. RAS# Active Time = 8 Clocks

- RAS# Precharge Time = 3 Clocks

- Write Recovery Time = Auto

- Write to Read Delay = Auto

- Read to Write Delay = Auto

 

Thanks,

Fred

Yes and this platform will run the memory at DDR200 with more than 2 double sided modules installed.

 

This is due to the limitations of the available VIA chipsets for Socket 754 motherboards. Had a given Socket 754 motherboard used an nForce chipset, three double-sided DIMMs would have been able to run at DDR333.
