What's Your FSB?

[Dual_Corex2]

Is that why I get better benchmark results and better performce with my BH-5's at DDR650 compared to DDR400?

There is no such thing as DDR650. The highest DDR there is would be DDR400. Anything higher (DDR500, DDR600 etc.) is nothing more then overclocked DDR400. That is why you get better performance. Another marketing seller.

Sigh.

You said it better to run with sync'd speeds. I can run it at DDR400 to be matched with my processor, but I can overclock it, which is essentially the smae as what you said with DDR2, You'd rather have DDR2-667 then DDR2-1150?

I dont know much about the newer stuff with DDR2 and all. I know that with DDR400 it was best to just run it with the cpus FSB, as you would gain a very small difference (if any) in performance as opposed to overclocking the FSB with the RAM.

DDR2-667 will run at 333mhz
DDR2-1150 will run at 575mhz

Im guessing with all the new stuff, the memory speed being higher then the FSB doesnt matter anymore. Also, the DDR2-1150 will allow for alot more bandwidth then the DDR2-667. You have to think about that as well. That is, if the CPU will allow it. Your memory bandwidth can also be limited by your CPU as well.

Even so, arnt you guys saying that Athlon 64s dont have an FSB? Mine does though, its 200mhz. I know AMD calls it something different now, but is it not the same thing? Everything is getting skewed for marketing if you ask me.

The AMD CPUs have an integrated memory controller, so no northbridge link, and no FSB.

Would this be in mhz or ghz? lol. Either way that is also incorrect. As stated earlier, there is no current cpu with an actual FSB above 266mhz (stock). The highest reached in an overclock was 640mhz. What you are thinking about is called AMDs HTT. Which actually, is much more advanced then Intels Hyper-Threading. I really didnt like the idea of Intels HT. I dont think it was really useful, all it did was make the system believe there was 2 cpus instead of one. Im not sure how that would make anything more effective..... But AMDs are also better since the memory controller is built into the chip, making it faster to access rather then having it on the board taking up useful space as Intels do.

Hyperthreading and Hypertransport are completely unrelated.

And technically speaking the FSB of C2D models and other P4 and other processors that are newer use the 1066MHz FSB WITH a bus of 266, the FSB is 1066

Other way around. FSB=266, effective bus speed=1066. Read the rest of the thread.

 

[Cromewell]

Instead, it will read 266mhz which since the Intel cpus have 4 pipelines

There's only 1 'pipeline'

And technically speaking the FSB of C2D models and other P4 and other processors that are newer use the 1066MHz FSB WITH a bus of 266, the FSB is 1066

Accurately speaking, the FSB of a Core 2 Due (say an E6600) is 266 and it transfers 4x per cycle giving it an effective speed of 1066.

You'd rather have DDR2-667 then DDR2-1150?

I would, but that's because my brain still functions and says it's silly to pay the price premium to buy those.

I know.......and? I was using AMDs HTT since thats one of the speeds they have in place of the fsb now.

 

[Dual_Corex2]

Thanks for clearing that up. Someone had told me that they had 4 and AMDs had 2 and thats why Intel cpus were quad-pumped and AMDs were dual-pumped FSBs. I was unsure of that information though. But it made since at the time

What do you think DDR400 is? Just overclocked DDR333 or DDR266

 

[Mankz_91]

nope.

DDR-500 ect. is what the RAM is garunteed to run upto.

the highest clocking DDR RAm that was ever on sale went upto DDR-700

After adding the DDR, the fastes RAM i think right now is 1192MHz out of the box. plu there is a 1066MHz FSB on the newer Intel processors. and I would take a 2.4GHz C2D over ANY AMD out there. and nice tripple post.

1. You should add "effective" after the 1192Mhz.
2. There is faster memory than "1192Mhz", in your language.

 

[Infected Cat]

Wrong..........you can now buy DDR2 which is capable of reaching speeds of 800 MHz. Depending on how you're bios is configured speeds of 800mhz can be achieved with PC2-6400 DDR2 800MHz. Configuring bios is not really classed as over clocking you are enabling certain options within the bios, where on the other hand software that has been downloaded, giving you the option to over clock is forcing the system that does not have these options to be over clocked.

They our selling 800 MHz ram on eBay check the link below..

he said ddr, not ddr2

 

[Dual_Corex2]

Yes, DDR and DDR2 have 2 different interfaces. But its possible to get DDR up to semi-DDR2 speeds like the 700mhz one that was mentioned. But they are not the same.

 

[Dual_Corex2]

nope.

Well hey now, i had a stick of "DDR500" ram and when i oced my cpu to 250mhz (which would be equal to DDR500) the ram wouldnt run, i increased timings and voltage still no go. So much for its "500mhz" speed

 

[4W4K3]

I've had standard DDR400 run up to 255MHz. That's ~DDR500. And I KNOW I've seen people top 280MHz with Corsair/OCZ RAM, along with other "no-name" stuff that turned out to be golden. I just really liked OCZ

 

[jedijeff123]

2000mhz FSB?????
i thought that 800 was second best......

Praetor put those in to fool AMD users

The highest bus speed now is 1066Mhz, while the 1333Mhz will be out soon.

I got my HTT speed over 1200mhz stable and i hear that HTT doesnt take to OCing well
