FSB speed and performance

Is the FSB speed have a significant impact on performance? Is the Pentium 4 3 GHz 800 MHz FSB a significant performance improvement over the Pentium 4 3 GHz with 533 MHz FSB? What about Hyper threading? Is it worth it? I also saw a P4 2.8 GHz 800 MHz FSB with HT on PriceWatch, but Intel told me when I called them that it has not been released yet? Can anyone tell me what's up with that?

Are Micron Technology, Samsung, OCSystem, Enet, WinBond, AIB, Mosel, and House Brand reliable and good quality brands of PC3200 DDR SDRAM to buy? Which ones of these are good, and which ones are crappy? Are any of these just as good as one of the best brand RAM you can buy?(I found the best prices on these RAM brands I listed. That's why I ask.) Also how important is the CAS Latency on the RAM? Difference between CAS2.5 and CAS2?

Micron and samsung memory are good, stay away from house brands and generics, spend a few more bucks and get something good.

the 800 fsb part will undoubtedly be faster. it should be purchasable soon.

the difference in performance from cas latency of 2.5 to 2 is somewhere around 5-15%, depending on the application... IMO i think its worth it, but others do not agree :)

I came from a 533 FSB 2.4 to a 3.0 Ghz 800 FSB P4, Its hard for me to judge based on FSB alone, so I wont. but I will say that HyperThreading is really amazing sometimes - for instance - www.shiznitt.com/wow.jpg

As for the memory question, the I have the gigabyte board, and I am waiting to buy some of the OCZ Mirrored platinum ram so I bought your basic kingston for the time being. I couldnt even install XP - I ran a Memtest 86, and on Stick one it found 116 errors, and on stick 2 it found 40,000+. I went out and got some samsung and that seemt to work fine. I doubt I had 2 bad sticks of ram, I just think the kingston doesnt like going that fast, at least not with the 875, but who know.

Here be the responses.
1. P4 3 with 533 is not significantly faster than its predecessor, yet will cost a lot more
2. Hypertreading is not used by many applications. Yet. But intell hopes to incoroporate it in new games in about a year or two. So far, the proggies that do use hypertreading are mostly 3d editors, and 3d graphics creating proggies.
3. It is not worth it.
4. probably a trip on pricewatch. so far, even the 2.4C (800 nhz) has not been released, yet alone 2.8
5. only Micron (Crucial inclusive), Samsung, TwinMos, Gail, Kington and corsair are the best. Ironically enough, Crucial can use either Samsung (best for OCing) or Micron chips, same with Kingston.
6. Look above. All of the ones above are good, and all the CL2 models of the categories above are really good.
7. Cas latency is important, but one still might find a CL2.5 performing enough. Heres my PCMark 2002 (ran on a clean installed Win XP with all the memory-consuming, performance degrading features disabled). CL2 (Corsair XMS, was ran in 2700 mode) had 4980 PC Memory marks, and Samsung CL 2.5 had 4580 memory marks. Difference is present, but so are the differences in prices. But i asume you planning on building a really fast/expensive computer, so go ahead with CL2
Good luck!

1 I have the P4 3.0 800FSB and it's great!!!
2 Not by a whole lot
3 what about it :)
4 It's usefull if u multitask
5 i don't think the 2.8 800fsb with HT is out yet
6 I like samesung Orig, see my rigs
7 not terribly important in apps, cept games
9 Probably not noticable, but it'll show in benchies

I have the 800FSB for the faster memory performance, i think it's worth the money if you have it, if not you can try the OC'ing route.

Help that helps!

Wow, i wish it was available when i was buying my rig :(!

You can prolly OC it to 3.0G easy, prolly without a voltage bump, ohh well.

the 2.8 800fsb is a better deal, it has HT i think too
