What do I look for to indicate interleaving?Quote:

If it can be done via Driver, I think WPCREDIT should be able to do the same thing without causing windows to crash? :confused:Quote:

Checking for interleave is a bit messy, the DRAM CS and Mask registers tell the story. Get 26094.pdf from the AMD web site and read pages 71-79. It explains how these registers work. The easiest way to determine if the banks are interleaved is to check if the Base addresses for each consequetive bank are offset by 8 bytes.
Damnn, i couldn't even begin to comprehend what bits to be looking for :(
Could you please make some kinda prog to select upto 8way interleave? :slobber: It should work with all A64s I assume?

Untill such time as Code Red can incorportate that bit into A64 Tweaker, RightMark Memory Analyzer v3.4 appearently shows interleaving status on my msi 250gb.
is there a way to disable the 1T on the athlon 64 3200+ with C0 stepping?
no, im afraid there isnt.
Where does it show that?Quote:

I havent found the option in the bios of my dfi or msi 250gb boards.
I would like to direct an inquiry to someone like Oskar.
FOR ALL:
Everyone may use Central Brain Identifier tool for memory tweaking:

My goal is to get superPI to less than 30 seconds at 238x11=2.62GHz, some dude gets 31s with his stock 3000+ so I got a long way to go still. bartons dont do as well, my friend has 38s at 2.6GHz on his barton, is this a bad or good number
Max async latency of 5ns is very good.Quote:

Is it really necessary to reinvent the wheel?
Max async has quite some impact on performance, but there are two cases it has to relax:Quote:

In my case my Hynix DT D43 can set max async to 7ns at 265MHz 2.5-3-3 for best performance. However once running 2 sticks, 8ns is a must for stability, and Vdimm won't help at all.
And at any non 1:1 ratio, 7ns is no go.
With only 1 stick, setting to 8ns won't let me go any higher.
Setting Max async to Auto in Lanparty BIOS is equal to 7ns in my case, for both 1 or 2 sticks.
Refresh rate (Tref) will have a healthy boost when set to 166 MHz 1.95us, but it might not apply to all memory.
My $0.04 :toast:

As codered said you probally need around that speed on a 1mb.. But it has to be on 1:1 - Otherwise there´s no chance..
so: 238x11=2.62GHz would not get you anyway near 30sec.. more likely 34 or 33 :)
And you friends barton is a bit slow -- I guess he´s using a fsb around 230 to get that result :)
"Refresh rate (Tref) will have a healthy boost when set to 166 MHz 1.95us, but it might not apply to all memory."
it says reserved value to me, does this mean unavailable or something? I also have the option to set ras-cas delay to 1, but im too chicken to try, should I? its also a reserve value and if it doesnt freeze will this help any?
On my (now dead) AN50R / 3400+ running async didnt affect my mem timings. I could run max async = 5ns up to 250 MHz and 6ns up to 276 Mhz. Although I did get the same problems with two sticks @ 6ns. For stability with two sticks I needed to use 7ns.Quote:

do i have to be running w64 or can i do the tweek with wxp?Quote:

I searched around for quite long and i didnt find anything regarding the Corsair Pc4400 (hynix -d5 IC's) and the setting we should use on them.
Τhe question is how to tweak them to get a really high fsb OR get a really good score with tight timmings.
My MOBO is a DFI Nf3 UT and i have a CO a64,so 1T only ;)
Any help would be greatly apreciated
codered i was using the ati driver:6.14.10.6490,things were going way goodQuote:

i didnt save it anywhere is there any magic you can due.... :)
Just ask around or search the standard mirrors. I am sure someone around here has a copy ... I could do with a copy too ;)Quote:
