Barton is 166fsb!?

[GRagland]

The barton cpu's are 166fsb (instead of 133) right? Well then wouldnt you need like pc2700 ram. What if my pc2100 can't go up to 166fsb?

Yes, you need PC2700 RAM to support 166Mhz.

so if i ran it with my pc2100 ram then it would be overclocking my ram right? or does it not work with pc2100 ram at all (i dont see why it wouldnt if the ram can take 166fsb).

Yes, you need PC2700 RAM to support 166Mhz.

Wellllllll, not to get technical...oh heck, this is a TECHNICAL type site. 😉

You need PC2700 to support a 166MHz front side bus at default (non-overclocked) speeds. With the proliferation of PC2700 memory, many PC2100 modules made by big companies (Crucial, Samsung, etc) are either rebadged PC2700 memory, or PC2100 memory that will easily do 166MHz.

Now, the caveat to the statement above is that if you buy PC2100 memory, you're only guaranteed 133MHz out of it, nothing else.

But, yeah, Barton's stock FSB speed is 166MHz. I'm waiting on benchies of this thing...most of us are already at 166 or better FSB speeds. I'm sitting at 180 and my systems' not breaking a sweat.

I'm pretty sure the memory ratio is asyncronous, you could use pc2100 at 133mhz, with no overclocking and still use the 166mhz bus. It would perform worse than something with pc2700, but it would still be possible.

 

[GRagland]

oh yeah, but i think my old epox-8k7a will not let me run my ram asynchronous from my cpu fsb, so i would have to run my ram at 166fsb. am i right?

Depends on the motherboard, though, and it's BIOS support w/a BARTON (not Pally/TBRed) CPU.

Not required but recommended.

Just run it as fast as it can go as long as it's stable.

Well I know my epox-8k7a doesnt support the barton, im just trying to get a better understanding of how fsb works.
On the epox 8rda, you select what percentage of the cpu fsb you want to run the memory at right? So with the barton and an 8rda if you set the memory to run at 100% the memory would be at 166mhz, but if you set it 50% the memory would be running at 83mhz right? And on the 8rda does the agp and pci run asynchronous from the fsb. If so, would there be any reason to overclock the agp speed?

Both independant of FSB.

n/a

 

[human2k]

166MHZ fsb is old, guys like thugsrock are doing 225MHZ fsb and higher.

IMHO - The usual async options offered on motherboards are FSB, FSB+33 & FBS+66. There is generally no provision to down clock the FSB. The only way to down speed the memory to FSB would by the use SD device ID option which sets the memory bus speed from the SD chip on the memory board.

How well any motherboard handles under clocked memeory is a matter of conjecture. With the price of memory it would probably be a good idea to purchase PC 2700 memory (or higher) with a new motherboard for Barton CPU's.

I don't mean to back up here, but why are you even considering a CPU that costs 100s of dollars when you have an old mobo and RAM? Why don't you buy a 1700+, new RAM, and an 8RDA, then overclock it to ~2GHz or more, which, at a 400MHz+ FSB would be roughly equal to a 2600+. Do you really think you'll see a difference between that and the 3000+ Barton? If you want to spend some money on a good air cooler and a good (read loud) fan, then you can get to 2.2GHz @ 400MHz+ FSB. That would be quite close to the 2800+'s performance.

Quick evaluation:
2800+ Barton: $400+ shipped

1700+ T-Bred B: $60
Epox 8RDA: $90
2 x 256MB Geil PC3500 Platinum: $176
Thermalright SLK-800A: $40
Good Fan: $10
------------------------------
Total: $376

Plus, you can sell your old equipment. Don't you know ANYONE that would like your old computer?

Yeah, thats exactly what I was planning to do. I know someone who would buy all my old parts, and I was planning on getting the 8rda, some pc2700 or pc3200 ddr, and the 2100+ tbred. I wasn't ever planning on getting anew cpu unless I upgraded my other parts too. But, I've decided just to stay with my current system for a while. I dont need to upgrade yet cause my 1800+ and 9700pro can run all games out well right now. Maybe in a couple months I'll upgrade.
