According to this document, CPU/DRAM ratio is 7, because CPU Multiplier is 11. Now, we can calculate a current frequency of RAM by the simple formula: 3003,12 / 7 = 429,0 MHz.

Yes, it looks easy, but can u tell me please, why are > 50% of the other tools show me 455MHz, including nVidia Ntune?

2200 / 333 = 6.606 =~ 7 | 3003 / 7 = 429, it looks like the same it is on S939 with DDR1. :)

trust him on this one. the memory speed is set from cpu speed by an integer... aka cpu/x, where x = ceiling (cpu multi / memory ratio)

the memory ratio is 5:3, cpu multi is 11.. ceiling( 11 / (5/3) ) = ceiling(6.6) = 7

so cpu/7 gives 3003mhz / 7 = 429mhz

this is exactly how the memory controller has worked ever since the s754 days, just with higher memory ratios for ddr2 now :toast:

btw, anyone else notice that the stepping indicates that the core has 1mb L2 natively...? most curious.

Yes, i trust him. But i'm intersted in, how the other tools come to the 455MHz. ;)

curious that i'm OCX_ozzimark in your quote :fact: :p:

and unlocking would just be like trying to unlock the upper multipliers.. not happening unless you have that special tool. :(
it's more.. odd that they are making chips with 1mb L2. i suppose they're planning something that they're not telling us? i don't know.

fsb * memory ratio = memory speed for intel chipsets
so 273 * 5/3 = 455
no surprises there :D

When a system synchronization clock is 200 MHz and a multiplier is x11 RAM doesn’t operate at 333 MHz, it operates at 314,29 MHz. Look at the picture below.

But if u do not want to use this table u posted, the other version of calculating works too, as it did on other A64s. :) (imho)

@coldbug

I hope someone will test the 65nm under subzero soon. But i think it has a horrible coldbug too.. :slap:

@cpu

Hmm, can't manage to get that cpu higher then 300xMHz. Will try more tomorrow and i hope someone can tell me a working mesureing point.

This board is a great clocker imho! :)

375MHz = reboot in windows / 372MHz = error in 1M. I think it is a great clock for a AM2 board, expecially bcs. u read that this boards suck at oc, all over the net! :confused:

At 365MHz cpu-z feels sick! :sick: It couldn’t detect motherboard’s sensor now, just FFFF. :D Cpu-Z’s system driver is unstable during your stress testing.

Congrats, BTW! :toast:

Lol, thats really funny.. :D 1M runs, but CPU-Z is unstable.. :p:

Thanks. ;)

Ohh, my Board runs max with 335Mhz. 365Mhz is realy great ;)

are you sure it's not the ht link? ;)
also, why are you running 8x multi when you have 11x available for use? :D

and that 1m time is rather slow for the cpu mhz :confused:

@HT-Link

It is on x3.

@Multi

Bcs. i can't get teh cpu > 300xMHz and i really need to know the real Vcore, before i start to push it more. ;)

@1M

Old XP from S939, 512KB L2, plus only 365MHz 4-4-4-8 1:1.

funkflix, run CBId, activate Mobility tab, now check Startup Voltage field in the Core Voltage / Core Frequency group. And this will be a default core voltage for your processor.

BTW, weather the P-States tab is enabled? (make sure Cool’n Queit option is enabled in BIOS, if it was implemented of course). It would be interesting to know what performance states are valid for Rev G1 processor.

Here is a screen with all the tabs opened, but P-States do not work. Do i have to install the Cool 'n Quiet driver in windows?

http://666kb.com/i/am529s9msoha34gl7.jpg

Startup Voltage is 1,1V. But don't know how the board handle that..

@M2N-SLI users, or maybe to all other Asus AM2 board users, i played around with timings now for about 4-5 hours and finally have found the fastest subtimings. Maybe it is usefull for someone. :)

I started with 11x273 DDR667 4-3-3-5 2T and all subtimings on Auto, this results in a SuperPi 1M time of 30.356s.

After i tweaked all subtimings to the max. i reached 28.984s with the same settings i posted above! :toast:

No, you don’t! Despite BIOS detects your processor (CPU String Name is constructed correctly), it doesn’t decompresses performance state tables into RAM, maybe because it is specific for legacy operation systems. Or maybe BIOS doesn’t know about all valid P-State tables. For example, when Cool’n Quiet option is enabled in BIOS of my ASUS K8V-MX, BIOS extracts P-State tables in RAM. CBId is able to scan memory ranges searching for the tables: Look at the picture below:

Hm, I’m a little confused. Well, for mobile and low-power desktop AMD64 processors Startup Voltage shows a real startup core voltage of the processor. For desktop processors it shows a default core voltage, not startup. And as I see, your CPU isn’t desktop, because it has a startup multiplier of 5 that differs from the maximum one. This trait is specific for mobile CPUs only.

Therefore, we can determine a default core voltage using another simple method. Look at the Maximum Voltage. It is equaled to 1.400V. In most cases it is resulted after adding 0.050V to the default voltage. So, we can get a default voltage using another simple formula: 1.400V - 0.050V = 1.350V.

Thanks for all the explanations VVJ!

After all, i think that teh actual bios of the board does not fully support the cpu!

If the Vcore is set to Auto in Bios, Cbid shows me a Vcore of 1,296V, what could be true if the defualt Vcore is 1.35V.

What do u think about that Vcore thing? :)

funkflix, frankly speaking, I can’t imagine how BIOS supplies the processor with a core voltage of 1.296V. 1.300V is the middle voltage value between 1.250V and 1.350V defined for an Athlon 64 3500+ Rev G1. Perhaps, it is an optimal choice when the core voltage is variable and BIOS doesn’t know what voltage value has to be set.

Think we are talking about two different things, hehe. I mean, when i set Auto in Bios, Cbid shows me 1.296V under General Information --> Voltage and Core Voltage / Core Frequency --> Current Voltage, while Bios and PcProbe shows 1,47V to me...

Anyway, if the Vcore is correct, which Cbid, Everest and CPU-Z is showing me, the CPU is really nice! But if the Asus stuff is right, and it needs 1.35V, then it is just a average clocker... Don't know if i will ever find it out?! :D

your prime is simply amazing, 2800MHz @ 1.2 :slobber: ^^

did you tried to sell the whole componets to destroyer...??? :p:
dont do that, at least the mb is crazy with this htt

Hehe, he is interested in the mobo.. :p:

Need 1,264V now for 2903MHz, prime runs about 30 minutes.
