TWINX2048-3200C2 and A8N-SLI Deluxe

Hello RamGuy:

 

A few days ago I assembled a new system consisting of:

 

CPU: Athlon 64 3700+ (San Diego core)

MB: A8N-SLI Deluxe (v 1.02)

RAM: TWINX2048-3200C2 - XMS 3202 v 1.2

 

The system was running perfectly well at 2.5-3-3-6 1T as that is the Corsair published specification. Yesterday I tried setting it as CAS 2 - I was expecting my system not to boot. Not only did it boot up, it sucessfully passed 20 passes of Memtest86+ (v 1.55) at the CAS 2 settings. I made no changes to voltage for the memory (default setting).

 

At first I thought that I had just gotten a extra good pair of 1GB sticks of Corsair memory and I was very pleased! After some thought I remembered that the Intel based systems were spec'd for CAS 2. I also knew that AMD had improved the memory controller on the two new cores (San Diego and Venice). I was wondering if these new AMD cores might be able to run the CMX1024-3200C2 memory at a lower latency for CAS than the previous cores? If so, I thought that you and others might be interested in my experience.

 

I have no complaint or problem at all. To the contrary, I am very happy with the memory and I got much more than I "bargained for" (in a very good way)! Thanks for the great support and products!

Actually Dave, with AMD 64 socket 939 CPU's we have seen that most were able to run at Cass 2.0 with out problems, just there is no way to single out the MB's or platforms other than AMD in general that will not run stable at Cass 2.0. I would suggest 2.7 Volts and you should be fine.

I know this is a slightly old thread, but I searched and couldn't find any similar threads mentioning this pair of modules.

 

I'm buying a DFI LP NF4 SLI-DR, and I'm looking at TWINX2048-3200C2.

I'll be ordering from komplett.ie, and the modules will be new.

Could someone tell me if the current revision of the XMS1024-3200C2 module uses TCCD chips and/or will it run on the DFI board (after I tweak the plethora of timings)?

I'll be running a 3700 San Diego.

 

Hoping to get a moderate overclock (HTT @ ~240 or so) while keeping the timings relatively tight.

 

Any info is appreciated.

Dlewis, I got here a kit of these memos and the same mobo as you. My processor is a Athlon 64 FX 55.

 

Please let me know your settings on bios, which bios and which slots do you use.

 

I cannot boot here with 2-3-3-6 with the same mobo

I can't reboot at the moment (processing and a large download going on) to check bios settings but the BIOS in the motherboard is version 1.008. The memory slots used are DIMM_A1 and DIMM_B1.

 

I will post the BIOS settings used later but I basically set up the system using SPD settings and manually changed CAS from 3.0 to 2.5 and then to 2.0. tRAS was changed from 8 to 6.

 

Let me know what other specific BIOS items you want and I'll post them later this afternoon.

Damn... San Diego should really make a difference...

Mine is using latest bios (1011), I'll check if I can use 2-3-3-6 with 1008.

 

CAS Latency (you already said it's at 2)

RAS to CAS Delay (you already said it's at 3)

Min RAS Active Time (you already said it's at 6)

Row Precharge Time (you already said it's at 3)

 

Please let me know the settings below:

 

Row Cycle Time (Trc) - It goes from 7 to a max of 22

Row Refresh Cycle Time (Trfc) - It goes from 9 to a max of 24

Write To Read Delay Time (Twtr) - 1 or 2

Read To Write Delay Time (Trtw) - 1 through 6

I just got a chance to check.

 

I don't have (at least I could not find) all the options that you listed. I think that either 1.009 or 1.010 had the added memory configuration options.

 

That said, I ran CPU-Z and saw that Trc was set to 12 clocks. The other parameters in your list were not shown in CPU-Z.

 

I'm tending to think that the new memory controller on the new cores allow for the lower latency setting. I have not had time to test the two settings to determine if there is any substantial performance gain. I suspect it will be minimal.

Thanks a lot man.

 

I'll check how it performs with bios 1008.

 

btw, you can squeeze a little more performance from it using A64 tweaker.

 

Update: I tested with bios 1008. No way.

 

Using bios 1011 again. I could squeeze 2.5-3-3-5 and really tight up timings on A64 Tweaker.
