A8N-SLI premium/TWINX2048-3200C2 questions?

[supaidaaman]

I just bought

A8N-SLI premium with TWINX2048-3200C2

Athlon 64 X2 4200

 

Will adjusting memory timings from auto void my CPU warranty?

What timings should i be using?

Is moving the ddr voltage past 2.75 going to harm my cpu?

anyone know what the hypertransfer is supposed to be set at?

1. No, they're supposed to be manually changed.

3. They're warrantied up to, but not over, 2.90 volts

 

2.

CAS Latency (tCL): 2

RAS to CAS Delay (tRCD): 3

Row Precharge (tRP): 3

Active to Precharge Delay (tRAS): 6

 

Memory Voltage: 2.75 Volts

All other settings to defaults.

 

4. 1000 / 2000. Depends on how the motherboard shows it. If it has one as an option, it won't have the other.

Memory timings or voltage settings have nothing to do with your CPU. The only ways to void your AMD CPU's warranty are intentional overclocking and/or overvoltage of the CPU itself and/or using a heatsink/fan combo other than the stock AMD boxed CPU cooler (or more specifically, any damage resulting from the use of such an aftermarket cooler). In other words, running your 3200C2 memory at 2-3-3-6 and 2.8V instead of 3-3-3-8 and 2.6V will not void your CPU's warranty - but running your x2 4200+ CPU at 2.6GHz and 1.6V instead of 2.2GHz and 1.35V will void your CPU's warranty.

 

And since your auto-detected timings of the 3200C2 series will always be 3-3-3-8 @ DDR400, manually set the timings to 2-3-3-6. In addition, 2.75V is the voltage at which Corsair formally tested their modules - but you can go up to (though not over) 2.90V without voiding the warranty of your Corsair memory modules.

 

As for HyperTransport, the default setting of Auto will use any speed from 200MHz (1x) to 1GHz (5x), depending on the application's needs. To stop such automatic speed alterations, manually set the HyperTransport multiplier at a fixed value (up to 5x).

i noticed there are other options past the 2-3-3-6

 

these:

 

Row Cycle Time (TRC):

Row Refresh Cycle Time (Trfc):

Read-to-write time (Trwt):

Write Recovery Time (Twr):

1t/2t Memory Timing:

 

should they be set at default?

1T/2T Memory Timing - also known as Command Rate - has nothing to do with your modules per se; it's just that Corsair tested the modules at 1T with one or two modules installed (the default is 2T). I'd recommend using 1T unless your system becomes unstable at such a tight command rate setting (in which case you should use 2T).

 

The other settings may be tweaked for improved memory bandwidth, if desired - but should really be left at their SPD-detected defaults. If Trc and Trfc are set manually, the important thing is to not set the Trc to a value lower than the sum of Tras + Trp. The Trfc should be set at 2 clocks higher than the Trc value.

 

Thus, if your 3200C2 memory modules are set at 2-3-3-6, the Trc value should never be set to a lower value than 9, while the Trfc value should never be set lower than 11. (Higher values are okay.)
