Help me choose new cpu!!!!

[Duvie]

What should I get ???

1) p4c 2.4ghz 800fsb

2) p4c 2.6ghz 800fsb

3) p4c 2.8ghz 800fsb

4) p4b 2.4ghz 533fsb *new D1 stepping*


Some of the things I have thought about is I need at least 3.4-3.5ghz or I will sell it and try again anything less and I don't meet my own qualification for an upgrade. I generally go 500mhz leaps at least but in this case I feel jumping to a DCDDR mobo and the advent of the 800fsb at least and HT will make a 300mhz leap still worth it IMO....


Some conclusions I have drawn myself

p4c 2.4ghz will yield higher fsb but will need to run in 5:4 mode and likely will need at least pc3700ddr so a bit more expensive. May be more difficult to obtain the high fsb stable on some mobos. Cheapest of the options.

p4c2.6ghz will yield a more moderate but still high fsb but should be manageable to most boards according to anandtech's 865/875 roundup. Also ram likley needed will only have to be pc3500. Can be find oem model right at 200.00 dollars.

p4c2.8ghz will yield the lowest ddr speeds but still too high unless I get some 500ddr to run in 1:1 mode and 5:4 mode runs memory speeds way too slow in my opinion. Most expensive.

p4b 2.4ghz...Unknown on performance but the high multiplier will allow me to run in 1:1 mode with near 400ddr speeds if the d1 stepping can come through and deliver a bit better then current c1 stepping chips that can hit 3.3ghz range.

Ive a 2.6c...Costa Rica...it boots at 275fsb on 1.65v but doesnt pass Prime95...I heard the Malay chips are better though...

[oldfart]

Dont get all bent on the 1:1 Vs 5:4 thing. It is really not that big a deal. The real performance difference between the two is negligible. You can save some $$ and get the same performance using a ratio and low latency memory.

You are striving for 3.5 GHz. That is a bit of a tough one. Most P4C will not get there. You have been very lucky in the past, so who knows.

A few numbers on 3.5 GHz:

2.4C
292 FSB
DDR584/467/389 1:1/5:4/3:2

2.6C
269 FSB
DDR538/430/358 1:1/5:4/3:2

2.8C
250 FSB
DDR500/400/333 1:1/5:4/3:2

If I don't think it is even possible with in 2-3 chips I will stop looking to upgrade for a bit...Igot to admit I am disappointed in the state of these chips....Makes me wonder if Intel is having difficulty ramoing up the end of the 1.3micron line...

[Duvie]

I will likely get the ram and mobo now, and try to take the performance increase of the DCDDR. IN 2-3 months the chips better be better!!!!:mad:

[oldfart]

They have hit the end of the line. The "C" chips generally are better overclockers as a whole compared to the 'B" chips, but the ceiling is ~ the same. What you get is Hyperthreading, which can be a nice boost depending on what you are doing. Going from SC DDR to DC DDR will give you a boost, but its not all that huge either.

[Duvie]

I agree it seems the line was hit, but I am still seeing quite a few regulars here and there at other forums that seem to be getting to 3.5ghz so I think I will try. The question is whether a 2.4c but with more expensive high speed ddr or the 2.6c with moderate speed ddr???

2.6@3.5ghz up to 1.6v with HT and DCddr running at 433mhz would be just dandy!!!

Still probably about 2 months off of cpu purchase, so maybe things can get better.

From a source I cannot reveal told me awhile back that they were producing several chips (.13 micron stuff) that was meeting intels specs of testing at 3.4 to 3.6ghz range so I am a bit surprised I am not seeing 3.8ghz more often and not just on vapo and water machines.

[LastRide]

I have been seeing the 2.6C overclocking like crazy lately.Its really a tough choice between that and the 2.4C You can still always run 5:4 450 DDR with a 2.4C .I am at 3.36GHz at 448 DDR 5:4 .The 2.6 looks great also though.

[Duvie]

So these newer 2.6c's coming out of newegg seem to be running 3.4ghz regularly with many taking them up to 3.5ghz....I have seen more and more lately but I need to do a bit more research on the wee kand batch of the chips...

Let me know lastride if you have any of that info...

[LastRide]

Go here to overclockers http://forum.oc-forums.com/vb/forumdisplay.php?forumid=2 They are always posting pack dates .This is a direct link to the Intel forum.I see a couple 2.6C threads.

[oldfart]

2.6@3.5ghz up to 1.6v with HT and DCddr running at 433mhz would be just dandy!!!
I agree. That would be a very nice rig.

[Duvie]

Like you said oldfart I have been lucky in the p4 ocing world...

1.8@2.4ghz w/ 1.65v 1/02
1.6@2.74ghz w/ 1.71v 6/02
1.8@2.61ghz w/ 1.68v 7/02

2.4b@3.24ghz w/ 1.58v 4/03

I likely will do it...The only question is if I wait a bit maybe the 2.8c (may drop in price due to prescott release) may be a better shot and get the hyperx pc4000 stuff and run 1:1 ratio??? What do you think???

[oldfart]

Who knows. Maybe Outpost will get some sweet OEM "bent pin specials"?? Just keep your eyes open for a good batch of chips.

You know my opinion on PC4000 high latency stuff. Its no faster than low latency ram running a ratio. There have been plenty of benches and reviews that prove this. I dont see why people waste their money on it.

You have a pretty nice setup. maybe just wait it out a little longer for Prescott?

[Duvie]

I can wait for prescott but I never am the early dopter or will put down that type of cash for a processor....I only have sepnt 200 or less on all my processors in the last 3 years. NOt going to change now!!!

I will likely get 2.6c for higher fsb run a 5:4 ration and get some pc3500 or pc3700 stuff in 2 sticks of 256mb...

[oldfart]

Yeah, I doubt the Prescotts will be cheap. If you get PC3700, be sure it CAN run good timings if you run 5:4. Some cant run good timings, some cant run 5:4 at all.

Your luck is about to run out.:na:

[Duvie]

Why is that lastride, or are you just yanking me???

[LastRide]

Just pulling your leg.I think a 2.4C or 2.6C you can't go wrong.I would go for the 2.6C personally.

Yeh

I am in the position, wot to buy????? So many things said bout the 2.4C & 2.6C which one!!??

I will go 4 da 2.6 :-)

[ThugsRook]

yea, you know what i voted for :deviltail

keep your current chip and just get the board and cheap ram :wave:

[Duvie]

Any more thoughts ppl???

[Thor]

I just got a Q320A339 Malyasia 2.4C that does 280fsb on default vcore (undervolted on my IC7). :D :-) :D

That is nice!!! week 39 right?? That is 3.36ghz undervolted below 1.525v???

This is what I am talking about....It is likely this chip is going to get close to that 3.5ghz range I would like to be....

[Jojo1971]

as we help duvie choose his future processor, can we include the "sources/store" where we can purchase those golden chips....nobody wants to buy a dud, you know...

Nope, week 20. I bought this locally and they had a few of them in stock, but that was about 2 weeks ago. I can go higher, but unfortunately, this chip heats up like a demon, and my air cooling doesn't suffice (Thermalright SLK900U) as the temps soar upward over 70C on my IC7 and eventually crashes because of the heat issue. But, I'm pretty happy with 280fsb at default vcore - yes, undervolted. :D

It's all luck of the draw, and this is my THIRD 800fsb cpu. My first was another 2.4 that did 275fsb and second was a 2.6 that only did 230fsb.
