Report your A64 timings

[alkemyst]

I am trying to figure out what's a good O/C and what's not. I am sure other's would like to know as well. There are a lot of similar postings out there but none really give you the whole picture. CPU speed is really only 1/2 of this.

HTT
CPU Multi
CPU Speed
VCPU
Memory FSB (as reported by CPU-z)
Memory divider (as 150, 166, 180, 200 or 300/333/366 etx)
VDIMM

Motherboard, Memory brand type/size, and CPU type.

Now a little known deal with the A64 is memory FSB is really a combination of the CPU divider, the HTT and the Memory divider. There is a table at http://forums.extremeoverclocking.com/showthread.php?t=151373 (attached to the post, but requires a login to access).

Basically say you are using a 8.5 multi on your CPU and the 166 aka 333MHz (5:6) divider on your memory. In reality your ram is going to get a 8.5:11 divider. This is why many think their dividers are screwy.

Your HTT isn't actually 295 or 300 because of the .5 multiplier. What it actually does is round the multiplier up and lowers your HTT. For the first one your HTT was really at 284.6 x 9 = 2562.

Thats a rockin clockin there Shim! I am amazed at how those Clawcastles clock! Better than the Winnies! Who would have thunk it

Damn thanks guys so far...good posts. I am currently going (back) through Zebo's post here and some of the other additions I have gathered.

huh? two instances of prime? you run two instances for processors with hyperthreading... one instance should be good enough for a winnie... (small fft's, not blend)... if you want to test ram use a program like memtest v1.51 or 1.55

 

[Elfear]

I run one instance of blend and another of small fft. I could be totally out to lunch, but I was thinking that it would cut down on test time (which my wife likes) if I run two tests at once. Both the ram and cpu are pegged at 100% so it seems to be working but maybe I'm missing something.

 

[Shimmishim]

i'd test them separately if i were you.

6 hours minimum of prime95 small fft's

and then loop test #5 for ... this is up to you... people have seen errors even at 300+ passes so... i'm not quite sure how many loops to run this for... i run it for a minimum of 100 loops

[alkemyst]

I failed PRIME95 (the middle torture test) after 7hours 45mins running
HTT=280
CPU=9x280=2520
VCPU=1.545
RAM=166MHz
Ram FSB=228MHz (according to CPU-z)
VDIMM=2.85
this is at 2-2-2-5

I was doing better on my A8N, which may be due to 2.9V on the ram.

I backed it down to 2-2-2-7 to try, but I may go back to 2-2-2-5 and underclock the CPU a bit.

 

[alkemyst]

passed almost 11 hours at 229 (not 228 like I thought) with 2-3-3-7 (again a mistake) timings....tried 2.5-3-3-7 at 180 MHz (252MHz) and it crashed almost instantly in PRIME95

 

[JoLim24601]

anyone wanna take the time and make up the avg overclocks of 3000, 3200, etc? lol

hmm d00d perhaps hmm read this thread as it progresses...

try not to be the n00b even though you are one.

3000 and 3200 are same cores....they will max out at the same max overall. beyond 3500+ the cores change, the fx cores are also different.
