A few questions ref: F1-3200DSU2-1GBLE

[farooqm]

I have G.skill LE PC4400 F1-3200DSU2-1GBLE, 2004 Week 10 memory.
Motherboard is Asus A8n Sli (Standard) with the latest Bios.

Currently running Opteron 146@2750 with 1.3785v Prime & Occt stable

Memory is running 1:1 @ 275 with 2.65v and the following settings 2.5,3,3,6 (at work so can't post screenshot until I get home), had to run it at 2T as my Asus A8N SLi won't go above 230 - 1T :(

Question1: what voltage can I safely use without having any direct cooling of the memory. (When running Prime, SmartGuardian App reports the temps as CPU(38c), PWMIC (37c), Chipset (34c) )

Question2: Whats the highest this memory will go upto 1:1, I have run CPU@3Ghz and mem at 300 with 2.5,4,3,7 but its not stable in any of the checking apps, and is not stable even when I slacken the timings off more. Voltage still at 2.65V, do I need to up the volts... and again whats safe without having direct fan cooling of mem.

Question3: Just out of curiosity, what is the min Volts for this memory... Lowest I've tried is 2.6 and upped to 2.65v for no real reason :)

Answer 1: under 2.8v is good without active cooling
Answer 2: ASUS is known problem over 300FSB and 1T with memory. if you increase to 2.73v and still not stable, it probably is becasue mother board
Answer 3: i had ran those memory with 2.5v in DDR600 no problem, but that is very depends on how good is the memory

Thanks for the quick response. Clears up a few things.
In answer 3 you've said that you ran this mem at DDR600, any idea what timings you used?

Whats the highest you manged to get this mem running CAS 2, as I had to switch upto CAs 2.5 fairly quickly..

DDR600 2.5-4-3-5 with 2.5v that is the lowest i ever ran, but 1:50 will do that, maybe less
for CAS 2 with 2.8v i only hit 210~215 i remember, or +-5,

Thanks.... was thinking my mem wasn't upto it, but it seems like it is performing as designed.

[farooqm]

Cas 2 seems like I can go upto 208Mhz max before it gives up.
Cas 2.5 still trying to get it stable at DDR600 2.5-4-3-7 using 2.7v, prime95 fine with CPU at this speed, but when I run the Stress RAM test fails almost straight away.

Can you offer any information on getting this stable running at DDR600?

[G.S Technician]

if you runing SP2004, make sure it is at blend mode!
for stress ram and stress cpu, it is actually stress your CPU most the time. if you compare with old prime95 software, you will see the stress ram and cpu from sp2004 is actually max heat and ALU test on Prime95

[farooqm]

I'm using SP2004 and not the old prime95 to test. I have not tried running the blend. I wanted to check both CPU and Mem individually. CPU test seems OK, but the 'Large, in-place FFTs - stress RAM' test fails straight away within 15seconds :(

Is this the best way or is there a better way to check ram at DDR600 speed ?
How can I get this stable at this speed.

Here is my A64 settings:

'Large, in-place FFTs - stress RAM'

it is CPU test not ram test! most ppl use this option to TEST CPU but not ram
