Basic questions (for you RamGuy !)

Hello Ramguy,

 

I have on now an Asus P4P800SE, with a P4 at 2,4ghz.

No OC, so my bus is on 200 Mhz.

Actually, I have two TwinX 256 XMS PC 3700, and my setup is configured as following (with your help a few years ago...) :

3, 4, 4, 8, 4.

Works fine.

 

I tried by past to OC to 233 Mhz, and all was ok, that is not my question.

 

I want to push from 1Gb to 2Gb, and certainly buy a new TwinX : 2x1024 XMS 3200 C2.

 

Can you confirm me that the parameters for this kind of memory ? 2,3,3,4 ?

 

Will it be faster with those news Ram ? Or is it better to keep my PC 3700 ? C2 latency will improve my speed ? Or is it better to play on the frequency ?

 

Thank's for your help.

2-3-3-6 as per the label, not 2-3-3-4.

 

Replacing your current memory will be faster in multiple respects:

 

1. Double the memory will help applications overall.

2. 2 instead of 4 sticks will lessen the stress on the memory controller.

3. Faster timings will give a small boost as well.

 

Overall it's a good choice. May or may not be able to OC the memory as well, but doubling the memory will give you the biggest performance boost.

Wired is correct. Additionally, if you increase your memory amount like this you will see the most benefit in situations where you have heavy memory usage and your system can make use of the new memory .

 

However, if you have been being limited by a CPU bottleneck or limitation, then changing only the memory amount or frequency cannot improve that.

 

But, moving to more memory like you are describing is a good choice.

Hello,

 

I bought my new RAM and will start with in a couple of days.

 

Corsair TWINX2048-3200C2PT - TwinX 2x1 Go DDR-SDRAM PC3200 C2 !

 

Just some confirmations, please :

 

DRAM CAS# Latency = ?

DRAM RAS# Precharge = ?

DRAM RAS# to CAS# Delay = ?

DRAM Precharge Delay = ?

DRAM Burst Lenght = ?

Memory Acceleration Mode = Auto or Activated ?

DRAM Idle Timer = Infinite or 0T or 8T or 16T or 64T or Auto ?

DRAM Refresh Rate = Auto or 15,6 µSec or 7.8 µSec or 64 µSec or 64T ?

MPS Revision = 1.1 or 1.4 ?

DRAM Frequency = Auto or 266 Mhz or 320 Mhz or 400 Mhz or 500 Mhz or 533 Mhz ?

DDR Reference Voltage = 2.85v or 2.75v or 2.65v or 2.55v or Auto ?

CPU VCore Voltage = Auto or 1.6v<x>1.95v ?

Performance Mode = Auto or Standard or Turbo ?

 

Thank's a lot for your help !

Hello RAMGuy,

 

Thank's for your fast reply, again.

 

I'll follow your recommandations, but the pdf you send me speak about 4 values for latency : 2-3-3-6, but I need 5 values.

 

Does it mean that I have to apply them like this :

 

DRAM CAS# Latency = 2

DRAM RAS# Precharge = 2

DRAM RAS# to CAS# Delay = 3

DRAM Precharge Delay = 3

DRAM Burst Lenght = 6

 

First item DRAM CAS# Latency is to set on 2, cause my RAM are some 3200C2 ?

 

Thank's a lot for this last confirmation.

 

Best Regards.

DRAM CAS# Latency = 2

DRAM RAS# Precharge = 3

DRAM RAS# to CAS# Delay = 3

DRAM Precharge Delay = 6

 

 

Typically you can leave this at the auto or default setting but, in the past, 8 worked best for me.

DRAM Burst Lenght = 8

 

Also remember to set the memory voltage to 2.75v.
