DDR2 800 MHz or DDR2 1333 MHz - Page 2

post #11 of 17
Thread Starter 
OK I just saw in one site that X2 CPU's support 1066 MHz

"X2 - Support for unregistered DIMMs up to PC2-8500 (DDR2-1066MHz)"

...and maybe this is the answer for my question!
tnx to all for your answers

Run prime95 for about 3hrs. If it fail then it can't do it.

clearly..... tnx

and one more....can you give me soem opinions for this memory (I'm going to buy it)

Corsair 4GB (2x2GB) DDR2 1066MHz TWIN2X4096-8500C5DF

memory has been veried to operate at 1066MHz at latencies of 5-5-5-15-2T at 2.1VDIMM

TEST SPECS
* Each module set is tested together at 1066MHz
* Tested and packaged together
- Packaged together immediately following system test:
* Tested at EPP SPD settings (5-5-5-15-2T) at 2.1V at 1066MHz
* SPD programmed at:
- JEDEC standard 5-5-5-18 values at 800MHz
- EPP standard 5-5-5-15-2T, 2.1V values

Guess what: I have those in my sig right now
All the revisions of this memory overclock fairly well; mine is a revision 2.1 with Qimonda 70nm ICs, capable of 1200 5-5-5-15 just by pushing 2.3V! The RAM fan is pretty useless though, the memory runs pretty cool and the RAM fan is known to die quickly; I sold that. I got this memory kit for $22 on Craigslist

Yeah, my find was really lucky... but I guess that's a privilege of living in Vancouver, which has one of the biggest and best Craigslist computer markets around

I need to come in here and say this because no one else is telling you:

With an AMD platform, it is ALWAYS preferable to have tighter timings as opposed to high frequencies. AMD systems see a greater performance increase with tighter timings.

Now, that's not to say that everyone that does this is wrong, but it is certainly true with DDR2.

There also used to be huge problems with AMD CPUs not being able to handle speeds over 800 when DIMMs contained over 1GB. This problem has largely been stamped out on newer CPUs (CPUs I think you guys are using) so this shouldn't be a concern for you guys.

However, my suggestion for AMD systems using DDR2 will always be to find a DDR2-800 set at 4-4-4-12.

Similarly, my suggestion for DDR3 AMD platforms would be 1333 at 6-6-6.
