whats this?

my rig does better at 3dmark using 8.5x327 166 ratio than 9x309 166 ratio.

Does this 266 MHz effect only come into play for 1:1 ratio

no it's a problem when you use half multiplier .

look at this :

The memory divider is another thing which requires study with this motherboard. In the BIOS there are options for 200, 166, 150, 133, and 100MHz memory buses when HTT is 200MHz. These function normally, but a second divider gets introduced when the CPU is using a half-multiplier, like 7.5x. Since the memory controller is onboard the CPU, memory speed is based directly off of the CPU speed. When using a half multiplier, the RAM will behave as if the multiplier is actually the one half a step higher. The math for determining the memory speed becomes somewhat complicated. In all honesty the best course of action is to use ClockGen or CPU-Z to find the memory frequency, they have the detection method built in. Looking at the memory tab in CPU-Z which shows the divider being used is especially helpful in understanding.

ok, i have more info :

it's a problem when you use half multiplier AND 1:1 ratio

this problem not exist when you use half multiplier and an asynchronous ratio

Complicated is an overstatement. All you need to do is divide the FSB(HTT) with the multi + .5 and divide by the actuall multi.

IE.
280*9.5 - 280/10*9.5 = 266Mhz

or

300*7.5 - 300/8*7,5 = 281Mhz

CPU-Z does not show the ram-speed correct when using half multis, nor does Clockgen.

Atleast not here with the newest versions..

yes it's true : i'n my case it's :

8.5x282/9 = 266

thanks, now its clear
so 1:1 uses integral memory dividers

for me it doesnt matter anyway since I have to use the 166 ratio (mem is limited to 267 MHz @ 3.6V)

the memory controller of my 3400+ is dead---> rma

I tired of this... I'm sending the K8N back and get my money back and sending the AN50R to Sweden and get it repaired (If i can find the warranty proof?)

I tried setting the voltage in mbm settings to 'GA-8KNXP' for my k8n mbm now reads my 5v as 5.06. My 12v reading also went up a bit.

[K32A]

Well, i did also try that, but it did'nt help either - I think that i just have to wait getting my AN50R back

Not sure if you can see in pic but its:

A64 3400+ @ 2.75ghz
Gigabyte K8NPro
KHX3200 BH-5 @ 2-2-2-6
CPU/14
1.7vcore/2.95vdimm/2.95vddq

Still plenty of headroom imho. Board is completely stock. WIll be doing mods soon!

Heres my new mem chip looking good Its a HyperX PC3000, do you know if its a BH5 or BH6 ?
Running in 2.5-2-2-5, I cant run CL2 if i use 1:1.. just if i use 200mhz option in BIOS btw.

very impressive kyosen

yea that rips kyosen. don't suppose you've got a radeon handy?
nice synced busses.

nVentiv Mach2 "stock"

This setup is screaming for a vmod. I have to run the memory at 166 to get 2.7ghz I cant even do 220fsb @ 1:1 with 2.95v

speed up and get some mods dude you realy need it asap

[Formann]

Got another one a few days ago.. was hoping for a CG chip, but no.

A64 3200+
0351 CAAOC
"9"..160
Cooled by a Vapo PE.. poor thing.


Stable? It was.. now its acting up on me. It refuses to run nature in 01 at more than 2650. I also suspect my AN50R to be the sinner here, cause I can no longer run 270HTT with 2.5LTD. Have to run 2x.

[2PiZzA]

Tell me please, does anyone own a CG-revision of A64?

I was watching this thread and it seems that everyone have C0.

Whats the stock vcore/vdimm/vdd voltages on the shuttle? Any other 64 boards that have the vdimm option to 3.3? thanks

[Matshui]

The stock vDimm voltages on the Shuttle is; 2,6v, 2,7v, 2,8v and 2,9v...
The vCore is from someplace under 1v to 1,7v and the vdd I can't remember - but it is something like max 1,8v or so...
