San Diego and 4x512MB = 1T?

[Aries64]

Hello fellow Forum members,

Is anyone out there running a San Diego chip and four 512MB (double-sided) DIMMs in their system at a 1T Command Rate? If so, please post your system specs and highest FSB and memory timings for me.

I would appreciate this and I think other Forum members would as well. Thanks in advance!

I thought someone said they did but I'm not sure if he said it was single or double sided. =T If it's true, it would be awesome!

Do they even make single sided 512s ?

I have seen many threads that show the 1t versus 2t is not as big a deal as thought. Do a search and you will find some comprehensive benchmarks showing an overall difference of 3% or something. I haven't personally seen any 4dimm filled Venice/San Diego chips doing 1t. They are doing PC 3200 however as opposed to PC 2700.

I'll be able to test the Venice with 4 double-sided dimms @ 1T theory in a few days hopefully.

First I have to get some other things working properly on my new system.


From everything i have heard though, you can run the 4 dimms @ DDR400, but it will be at 2T.

Mine's definitely not.... but it's not really affecting performance....

officially AMD states that only single sided DIMMS will work on 1T, when four slots are occupied, but i would be interested in whether you could push 1T on them, maybe some chips might be able to do it.

Yes, I know that the theoretical difference is minimal, but for me the difference between 1T and 2T is 8+ FPS. Not a world of difference but still enough for me to keep my main rig at 1GB instead of going with 2GB. Its just that I have a "spare" 1GB Mushkin PC3500 Level II DualPack just sitting in my desk drawer. Expensive, useless, high-end memory.

Please post your results later n7. That will suck if you still have to run 2T. I was hoping that the NF4 and San Diego/Venice revisions would allow the use of tight timings and 1T Command Rate.

One can only hope, RichUK.

OK, nice thread name.. but i don't see an answer.... Can they do it.. or not?!?!

reviews say u can run 4 single sided modules at T1 400MHZ, and 4 double-sided at T2 400MHZ.

Thanks for the straight answer BlingBlingArsch. I was hoping the new (Revision "E") chip would be able to run four 512MB DIMMs at 1T.

I like the 1T timing for games, but it would be nice to install another GB for high-res photo editing in Photoshop and other image-editing software. Guess I'm SOL for now.

4x512MB definitely wont work at T1 with a Venice on a DFI Ultra D mobo.

 

[BlingBlingArsch]

and why?
