WR? 2x512mb BH-5 @ 282mhz 2-2-2-5 @ AIR!

[funkflix]

Yes i do!

Some more benches -

11 x 295 = 3245MHz | Divider = 183









10 x 325 = 3250MHz | Divider = 166









Now with 3250MHz and a real ramclock of 250MHz!









- and finally the 1M run from page 2 :

easily checked with the vdimm. if it were 231 on the bh-5 they should run with 3-3.1v. but i need 3,3v to get this memtest / primestable!

What do you mean by "the controller does not allow to go at more than 180.." 200 divider works fine @ 11 multi its true 1:1. Use the A64 mem calculator to calculate the tricky 183 divider. Destroyers mem did "only" run @ 261 Mhz.

I was refering to what Franck (creator of CPU-Z and Clockgen) assumes. This directly refers to what Oscar Wu told us in one of his threads, about memory dividers:

I think you know DRAM frequency we set in A64 register is " Upper limit " of DRAM speed ... A64 memory controller will automatically choose a smallest interger divider(>4) to generate the DRAM clock from Core Frequency , and the DRAM clock will not be faster than the uppder limit ... Using an oscilloscope and check all the multiplier from 4~12 with the same register setting in A64 ... What I got are 200/183/166/150/143/125/100 may be the upper limit of DRAM speed when you set correspoding register setting in A64 ... Here is the divider table I got after using an oscilloscope to check the possible upper limit of DRAM clock ... What I can not be sure is the exact frequency besides 200/166.67/133.34/100 ...

If 183 is in fact 183.333333... then (200x11)/183.333333 = 12.000000
Franck, most likely takes this value as 183.000000, so he gets (200x11)/183.000000 = 12.021857 and in result ~13.

I learned it the hard way months back (Aug 2005) with my 3700+ when I wanted to bench SPi32M @ 307x11 div183. I could not do it for the life or me and was puzzled because CPU-Z was showing 259MHz. Memory was 32M-stable up to 278MHz with div200. After a while I figured that something is not right and did some benching... After that, it was clear to me why I could not even boot at 307x11 div183 - because RAM in reality was running @ 281Mhz...

That is the other point u can proof it's not 250MHz, like in my screens. I normally do not need + 3,5V for 250MHz..

[dinos22]

this is obviously a 12 divider..........and whoever doesn't believe it has some issues

Then who tells Gogar, and all the other people who wrote those little apps to help calculate the real mem frequency, that there's an error in their calculation?
