P4 performance lately

[Neo_peter]

I was wondering, how well are the P4 2.8s and 3.0s OCing lately? Info on all varieties of 2.8 and 3.0s are welcome. I'm basically giving my brother my P4 so i'm planning to build a brand new rig since i have a few spare parts. WD200G, radeon 9800, all optical drives. This will do some CAD, and some games like need for speed underground 2, and HL2... I'm considering getting a 3000+ S939 Athlon64 cause it's cheaper... But I really lke Intel systems. Anyone have any comments or suggestions. Thanks

If you want to game, AMD all the way. If you're a mild gamer, i still think Intel is a great choice. Are you looking at the newer pressy's, or the older northwood's?

[Falkentyne]

If you want to game, _ANY_ high end CPU is good.
An overclocked Northwood, Prescott or EE, while not as fast as a FX55 (overclocked EE about as fast as FX53) will do excellently, AND you have hyperthreading, which can make a huge difference.

I have my EE at 3.81-3.83 ghz, which is at least as fast as a 4.2-4.3 ghz Northwood (depending on the program). And why the heck should I get an A64? To go from 100 fps to 120 fps? Are you kidding?

(the only compelling reason to go A64 is if you already have a slow system now and are doing a big upgrade, or if you have a fast system but can't resist having SLI--I don't know if any P4 S775 boards are SLI capable, yet).

Tell me whats more important?
Getting 120 FPS in Unreal tournament 2004, and getting messaged by someone on Trillian, and having your computer stutter when the message happens, or getting 95 FPS in UT2004, and having NO stutters when you get messsaged (Hyper-threading at work?).

Answer that.
Ask any FPS nut--it's much better to have a consistent stable high FPS, than a FPS that jitters from really high to occasional lows.

Which EE do you have? I have a p4 northwood 2.8C in my system, and it seems to be maxed out at 3.4 ghz (243 FSB) anything above this setting and it crashes or locks up during benchmarks. I think this is a pretty good performance boost - almost 25% with a 40 dollar zalman heatsink :) I was told that the 2.8C will not go any higher than 250 FSB, which I'm not sure is true. I have never had an AMD so I can't really compare them for ya. ;p

[Jimbob7]

2.8c @ 3.7 high vcore tho, depends if you want to go that far, if you can get a m0 2.8c then you should be looking at a high overclock. :)

[Opio]

Nice Jimbob.. I think thats the same processor I have, I'll have to check when I get back home. How did you get such a good overclock on that? (what heatsink/PSU/bios settings or any other settings?)

[Mr.Guvernment]

i just got my new 3.0C and off the bat i got it to 3.9ghz with a cheap thermaletake volcano - i think cooler and using pc3200 with a 5:4 ratio

i got it to post @ 4ghz but i had 1.8v into it and it was getting hot so if i get my water cooling then i will mess with it also once i get better ram - i got an abit Ai7

personally as the 2nd post mentioned - if u do more then gaming get an intel - it seems to be the better "all around" chip.

Oddly enough, when I run my EE @ 2.8 ghz with the L3 cache OFF, my P3-S Tualatin @1575 system actually almost matches the 2.8 ghz in several games (obviously not in Quake engine games)--in Battlefield 1942 and Vietcong, the performance is very similar (just a little bit above my P3-S). But when I let'er rip to 3.8 ghz with L3 on, that's like effectively 1.5 ghz faster...no contest.

BTW I have a 3.4 EE. Chip has not degraded in overclock, probably because I don't leave it overclocked 24/7, nor when I'm not playing a game.

[Neo_peter]

From what I've been hearing around the AMD camp and my friend which just got a new A64 3000+, there's only stuttering when they're running a lot of cpu intensive things in the background. Under normal circumstances there shouldn't be any. And I usually don't run much in the background. How fast does the newer stepping Northwoods and prescotts clock up to?

[DamienKC]

my M0 2.8c could only do 243FSB stable, any higher it wouldn't boot. This was with a SP-94 and tornado. It *MIGHT* have had to do with the 865 chipset, but i see alot of people seeing a barracade at 243FSB with the 2.8c, which still isn't a BAD overclock if you think about it.

[Neo_peter]

What stock frequency would I most likely have to get to break 4Ghz? I'm just trying to work out the pros and cons to getting a system of similiar cost either going A64 or P4. And I'm also trying to estimate how much effect this stuttering would cause in LongHorn because if it stutters now, and XP consumes enough resources already, I predict that LongHorn may have more background processes running which may amplify the stuttering. Another thing is, the northwood Cs are the ones I want to get, I'm still afraid that the new big heatsinks may warp my mobo, but the northwood Cs sell 30$ more at my local computer store, and because I live in Canada, there aren't any online retailers (including shipping) that can beat the price of my local store.

Why do i still hear ''amd is the way for gaming'' while this 2.8C kicks ass in pretty much every benchmark and was a good tad cheaper then most A64 which dont even come close.

Ok, i may be just lucky with this chip but still ;)


@ Neo Peter


Some 2.8 and 3.0 will do 4 Ghz, but a 3.2 or 3.4 is more likely to handle it properly.

agreed my 2.8c is awesome at gaming no lag at all...

and what cooling are you using (and vcore) to get that 4.0 on a 2.8c :drool:

i have a 2.8c sl6z5 MO stepping and i want to get it stable around 3.4 to 3.8 anywhere in there would rock :attn:

[Neo_peter]

But even if I got a great 2.8 or 3.0, i probably can't get the RAM fast enough to run it... Fast RAM is so expensive.

[Sjaak]

I can only run it 4Ghz on cold days...else it overheats too much lol. Right now the weather is fitted for about 3.7Ghz (1.6 vcore, i need 1.68 for 4 Ghz). Im using a zalman CNPS 6500B-CU with a 120 and 92mm fan on the bracket.


@ Neo_Peter

i am using cheap ass ddr400...running it 5:4

[Daewood]

nice i cant wait to get my mobo back and test the cpu i got to see what she'll do... and i got a thermaltake spark 5+ with an 80 to 70 fan duct running a 80 mil vantec tornado...

[Opio]

here is a screenshot of my cpu in cpu ID and mbm5.. I am running 1.65 core voltage, and the 61 is my 9800 xt temp in ati tool. hopefully it comes out ok ;p

[Mr.Guvernment]

But even if I got a great 2.8 or 3.0, i probably can't get the RAM fast enough to run it... Fast RAM is so expensive.

i am running pc3200 in my system with a 3.0c @ 3.7 right now - and it booted and posted @ 4ghz witha 5:4 ratio.

[Neo_peter]

Opio: how fast are u running those Corsairs?

Mr. Guvernment: What brand and speed of mem do u have?

[Circaflex]

my 2.8C seems to be doing well :D

[Neo_peter]

CircaFlex what kinda of cooling are u suing, seems like a very good OC for u, congrats.

[Circaflex]

Zalman cnps7000alcu soon to be h2o

[Sjaak]

Thatsd a real nice oc man, but watch the voltage. When i just got my 2.8 i ran it 265fsb (3.71Ghz, a little lower then your screened clock) at 1.588v, are you sure it needs the 1.6xx to be stabile?

With H2o, you might even take the ram on 4:3 tight timings and go for 4Ghz :cool:

[Neo_peter]

Do any of u know if the PAT technology is really any use at all on the i875Ps?

[Circaflex]

in the bios its set to 1.6 it boots up at default (i think 1.525?) but it isnt stable.

[Neo_peter]

Do these new prescotts hate voltage just like the old northwoods? Cause I've noticed many people with over 1.75V with the old northwoods to have dead chips after a year or so of use.

People, I have 200 bux doing nothing in drawer. For the best bang for the bux, should I buy one of the following:

Pentium4 2.8E GHz HT, C/1MB, FSB 800, Socket478

Pentium4 3.0 GHz HT, C/512k, FSB 800, S478

Pentium4 2.8C GHz, HT, C/512K, FSB 800, S478

PC3200 512MB x 2 pieces

Currently my machine is Asus P4P800, P4 2.4C (c/512kb, 800mhz) @ 3.2 GHz, PC3200 256MB x 2 pieces @ 540 DDR ( 270 fsb ), ATI 9800 Pro.

Lately my hobby is doing digital photography and small video editing. With existing machine, opening a photography folder with thumbnail view is little bit slow.

Thanks for the input guys !!!

[Neo_peter]

If ur going to stick to S478 don't get a prescott. It's still a little too warm for comfort.
