Well...I am just wondering how you get the info of the CPU's Internal Multiplier? I know to get the rate of the internal speed we gotta multiply the multiplier by the FSB. But how to get the Internal Multiplier's information? and that is a mystery to me.
If you know what chip you have, you can go to wikipedia for a list of every chip made by AMD or Intel, complete with details for each model number.
CPUZ doesn't have to be installed. You simply download it and run it. Alternatively, just look at your 'system properties' in My computer and tell us what CPU you have, and we'll tell you.
Well...I would like a physical way a method to get the info of the real speed of the clock multiplier or the CPU multiplier before you could determine which board, memory and CPU to buy. Assuming if you have no PC or computer, you won't be able to find this info or look it up online since you have no computer, not to mention about the installation of the software. There must be a way to get the info without using any software a computer so that the speed of the CPU could be calculated. I hope you guys could help.
Sorry, but your options are to use software, like CPU-Z, to tell you or look at the CPU and research the specs online. Maybe the box it came in would have but I'm not sure.
sammorris! I have seen you have built several awesome PC. My question is like how you do get the info of the CPU multiplier? Are you doing the same thing as what you are telling me to do by using a certain CPU software tool? Or this has to be done online and we cannot do anything about it? Because I have seen lots of people talking about the CPU multiplier when they purchase computer parts esp CPU, RAM and the MOBO.
Every CPU model has a multiplier, but that never changes. Say for instance you want to buy a Core 2 Quad Q9550. That CPU has a multiplier of 8.5, always. No matter when or where you buy one, if you buy a Q9550, it will always be 8.5. Buy a Q9650, however and it will be 9. As you see, different CPUs have different multipliers, but there's no variable, you just need to look up which type of CPU has which multiplier. That can either be done with the CPU finder website I just showed you - all you need to do is type in "Q9550" and it will show you the CPU(s). The intel website also shows the steppings of each CPU. Think of these as 'revisions' - nothing fundamentally changes whether you get a C1 (old) stepping Q9550 or E0 (new) version, they're both 8.5x333 = 2833mhz, they perform the same, but the E0 chips will overclock better. Or, when you go to buy a CPU, the multiplier will often be printed in the specifications (and if it isn't, you can work it out from the core frequency and fsb speed)
How can I work it out from the core frequency and the FSB speed? Is it a match calculation? Hope you could help.
Will there be any difference between AMD and INTEL and the MOBO made specifically for them? Here is the Intel Quad Core: Intel Core 2 Quad Q8200 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115055 Here is the board: BIOSTAR G31D-M7 LGA 775 http://www.newegg.com/Product/Product.aspx?Item=N82E16813138142 So I take 2.33GHz/1333MHz = Mulitiplier? Is that right? So what about AMD CPU and Hyper transport? Should I do the same thing as I did to the INTEL CPU and FSB?
No, remember that Front side bus for Intel CPUs is multipled by 4. A 1333mhz FSB is in fact a 333mhz FSB, so 2333mhz on a 1333mhz FSB is in fact 2333/333 = 7 Why are you so obsessed with working out the CPU multiplier anyway? HyperTransport works completely differently to front side bus. With AMDs, the front side bus is almost always 200.
Yes...Not sort of obsessed with it, but once you start learning, and if you don't understand, it will be a really a frustrating experience. And you are very frustrated because of that, besides I think once I get the hack of it, it does really help me to choose the proper components for assembling my PC. So I think it will also help me to solve the bottleneck problems. BTW, why do we have to multiply by 4 and why AMD is 200? Have they been standardized to be multiplied by 4 for INTEL and the FSB of AMD is always 200?
Just wanna confirm again...Sorry for any inconvenience So the multiplier of the INTEL CPU is always multiplied by 4 no matter which intel CPU it is? And AMD is always of base frequency of 200mhz? But would you please show me how to get the HT(hyper transport) of AMD? Same method as intel CPU FSB?
No, the FSB is always multiplied by 4. The Multipler belongs to the CPU as we previously discussed. You can't calculate the hypertransport for AMD CPUs - Hypertransport isn't the FSB.
The Intel Core 2 Extreme series allow the multiplier to be increased via system BIOS. Has anyone played with this as a source of OC? Dick
I would like to, but sadly have never laid my hands on one. It's effective though, as it can push CPUs well beyond the boundaries of normal motherboards.
