Explain RAM chips

post #1 of 6
Thread Starter 
Could someone explain the different ?chips?, I think that's what you call them, of RAM, i.e. TCCD, UTT, ect. And could someone tell me what are the pros/cons of each chip, such as high FBS, but loose timings and such. Last thing, how can you tell what the RAM is? Is there a certain model number to look for?

If you can find out here is a short summary from DFI Forums. It tells you what type of voltage chips perform best at. I.E. Answer the question, "Will I have to do a volt modification to my motherboard to produce the necessary voltage?" I am facing this same question right now. Here is the list.

Here is a short summary
------------------------------
Micron 5B-G
There seems to be a lack of info so some of this may not be accurate.
- When overclocking it will require a bit more voltage, can take 3.2v.
- You must increase the timings.
- 2-2-2-5 timings @200Mhz with only 2.6v
- 2.5-2-2-6 timings @250Mhz with only 2.65v
- Maximum overclock varies, some say 280Mhz+ is possible.

Micron 5B-D
There seems to be a lack of info so some of this may not be accurate.
- can operate at 2.6v @200Mhz
- When overclocking it will require more voltage, can take 3.0v
- You must increase the timings.
- 2-2-2-5 timings @200Mhz (recent findings)
- 2.5-3-3-7 timings @200Mhz
- 3-3-3-8 timings @250Mhz with ~2.7v
- Maximum overclock varies, 300Mhz is possible.

Winbond UTT BH-5
- Requires 2.8v @200Mhz
- When overclocking it requires more voltage than CH-5 at the high frequencies
- Can maintain low timings at high frequencies
- Gets very hot, must be cooled

Winbond UTT CH-5
- Requires 3.0v-3.2v @200Mhz, more than UTT BH-5
- When overclocking it needs less than UTT BH-5 to achieve the same results.
- Can maintain low timings at high frequencies
- Gets very hot, must be cooled

Samsung TCCD/TCC5
- Requires 2.6v @200Mhz
- When overclocking it still requires less voltage than UTT BH-5/CH-5
- Timing must be increased when you overclock
- It will reach a higher overclock than UTT BH-5/CH-5 (300Mhz is possible).
- Helps you get a good overclock out of your CPU too. <better for 1:1 ratio
- you will never go beyond 3.0v (Do not go over 3.0v), so it does not get as hot.
