Need ID HTT bus

[Pancho]

Re.: Need ID HTT bus

 

Hello,

 

The term "HTT bus" seems to be used to refer to multiple items.

I need to ID the term re. the specific reference below.

 

The following quote from the OC'ing guide/forum/et.al. makes reference to an "HTT bus".

Which screen number in the following image (see link) represents the settings for the HTT bus (in red) in the quote ?

**********

but

 

its not stable!

 

the HTT bus is too high...lets drop it down to 3x HTT...

 

280x2 = 560Mhz DDR time 3x HTT = 1680Mhz HTT

 

now we get back in the '1200-1800' range. Much more stable as we know our A64 will max Mhz @ 2660 for example just like the AthlonXP.

The HTT bus is the speed of the Hyper-Transport Link

 

In the BIOS it should look something like this

 

LDT/FSB Frequency Ratio....................... - 3x

No kidding. Have already wikpedia'd it, etc.

My posting even contains the very info you think you imparted.

How about a simple answer to my simple question?

Is it on these screens, yes / no ?

If yes, which screen ?

If no, then no.

 

PS. Please, this does not have to be typically and needlessly repetetive and pedantic.

These postings should not be a waste of our time. Am asking for help.

Just a simple answer to a simple question.

How about an image link that works?

Same here!

Well, 4. But if you actually did any research on your own, like read the entire Wiki article yould already know that.

The term "HTT bus" seems to be used to refer to multiple items.

I need to ID the term re. the specific reference below.

 

Simple Answer:

 

'HTT Bus' actually only refers to one thing:

 

The Bus on which data travels between the CPU <--> Northbridge <--> Southbridge

 

There are 2 things that determine the HTT Bus Frequency: The HTT Frequency & the HTT Multiplier. Multiply these 2 things together & you get the HTT Bus Freq. (i.e. 200x5 = 1000mHz = 2000mHz DDR)

 

 

Not So Simple Answer:

 

Let me first say that I have not used the LP NF590 SLI-M2R, So I may be wrong, but, It looks like the only thing different between the NF590 SLI-M2R & the NF4 is the addition of a southbridge, and therefore additional settings to determine the bus speed between the SB & NB.

 

So here we go...

 

On A NF4:

 

HTT Frequency. This is what determines the Speed of the HTT Bus & the CPU. If we set to HTT Frequency 200, & we set the CPU Clock Multiplier to 10, we get a CPU Clock of 2000mHz (200x10). Then, if we set the HTT Multiplier to 5, we get a HTT Bus Frequency of 1000mHz (or 2000mHz DDR).

In my case I have the HTT Freq. set to 300 & the CPU Multi to 10 for a CPU Clock of 3000mHz. My HTT Multi is set to 3x so I have 300x3 = 900mHz (1800mHz DDR)

That is how the HTT Bus Speed is calculated between the CPU <--> NF4 Chipset.

 

 

On a LP NF590 SLI-M2R

 

CPU/C51 HTT Frequency. This is what determines the Speed of the HTT Bus & the CPU. If we set to HTT Frequency 200 (3), & we set the CPU Clock Multiplier (2) to 10, we get a CPU Clock of 2000mHz (200x10). Then, if we set the HTT Multiplier (4) to 5, we get a HTT Bus Frequency of 1000mHz (or 2000mHz DDR). That is how the HTT Bus Speed is calculated between the CPU <--> Northbridge.

 

It looks like the (5) & (6) are used to determine the HTT Bus Speed between the NB <--> SB. The same concept above applies here, except (5) doesn't affect the CPU clock. If we want to set the NB <--> SB HTT Bus to 2000mHz, set (5) to 200 and (6) to 5. 5x200 = 1000mHz (2000mHz DDR).

 

 

In Short:

 

2.) CPU Multi. This is multiplied with (3) to determine CPU Clock Speed

 

3.) HTT Frequency. This is multiplied with (2) to determine CPU Clock Speed & with (4) To determine the CPU <--> NB HTT Bus Speed.

 

4.) HTT Multi. This is multiplied with (3) To determine the CPU <--> NB HTT Bus Speed.

 

5.) NB/SB HTT Freq. This is multilpied with (6) to determine the NB <--> SB HTT Bus Speed.

 

6.) NB/SB HTT Multiplier. This is multilpied with (5) to determine the NB <--> SB HTT Bus Speed.

 

 

Again, some of this is speculation, since I have never used the LP NF590 SLI-M2R, but I think that it is all correct. If I have any of this wrong, please correct me.

nice stuff PhoetuS,

There is a BIOS tutorial for this board you can look over.

 

Search and kindness and respect are your friends here at da Street.

Praz,

I just tried the link, and it works. Don't understand what the prob. could be. Would greatly appreciate your contribution.

Here it is again:

Phoetus,

Thanks for the effort. I think the answer is #4. What do you think ?

 

Others,

Wow, it only took 9 replies to get an answer, #4. If you don't want to help or talk about computers, and you believe that your internet mission is to assert lame witticisms and juvenile name calling, then just keep your itty bitty fingers off of the keyboard. It's almost like keeping your mouth shut, only easier. One tip though, it's more fun to just talk about computers, remember them ?

Phoetus,

Thanks for the effort, but could you read my posting, and answer its question. It's a specific question, derived from the OC'ing tutorial on this forum. I am assuming that the author of the quoted phrase knows what he is talking about, that he is seeking to share the benefit of his knowledge and skill, and that he is using the term "HTT" to specify something, not to assert a generality. It seems that he is clearly referring to a screen setting in bios. Which of the screens in the link do you think he is referring to ?

I think that if you read my above post, you will know what I think. I detailed, by number, what each setting does on your image.

 

 

Others,

No It didn't. See Post #6.

You are the one who came in here with an attitude, and everyone else simply responded to your bad attitude and appearant unwillingness to listen to an answer.

 

cuoficr gave you a reasonable answer to your question here:

The HTT bus is the speed of the Hyper-Transport Link

 

In the BIOS it should look something like this

Though, it may not be exactly the answer you were looking for, it was a step in the right direction without any negative attitude whatsoever. Never the less, you respond with this scathing post:

No kidding. Have already wikpedia'd it, etc.

You are the one that is out of line here, not anyone else. If you come in here with a bad attitude no one will help you (or perhaps, not many will help you).

Kingfisher is absolutely correct when he said that Search, Kindness & Respect are your friends here at the street.

OK...

With that out of the way, I'm not convinced you read and understood my previous post. Re-read it. The answer is not just #4. Pay special attention to the 'Simple Answer', then pay special attention to the 'In Short' section.

 

 

You Asked:

The following quote from the OC'ing guide/forum/et.al. makes reference to an "HTT bus".

Which screen number in the following image (see link) represents the settings for the HTT bus (in red) in the quote ?

 

The Answer to that question is: #3, 4, 5, & 6. Yes that is correct, all four represent the settings for the HTT Bus.
