If you're talking about GHz, you can easily overclock Pentium D 805, which will easily hit 4-4.2GHz. 3GHz on C2D will outperform anything else offered by AMD.

Besides, didn't I state somewhere in my guide asking readers to "Use this as a guide to learn, and judge for yourself." I didn't ask people to follow my guide entirely.

All I'm trying to do is write a guide that would help people out, just like in the early days, when I needed help, instead of starting a thread in every forums asking what kind of budget parts I could go for a good, cheap, overclockable system. This is a single guide, or should I say, a guideline, to what you can potentially do with $450 bucks, if you have more money to burn off, hats off to you, but not everyone is as fortunate as you, to burn more money else where.

And stop arguing about the PSU already, I've already addressed that issue if you read through the whole guide, I said, that part is the only part that I had doubt over.

And you just mentioned 3GHz is nothing fantastic on E4300, but didn't you say that E4300 has problems achieving 3GHz on stock cooling?

No, I never said anything about it having trouble reaching there, but what I did say is that your temps are going to high even on a conroe, and with that crappy psu it most likely won't be stable

The temperature is in fact below Intel's specified max temperature of 61C. The PSU is running stable for now, and I have yet to see any problems with it.
Like I said, once I encounter problems with it, I'll let everyone know, and will warn everyone of it.
For now, 4 systems running on that PSU aren't giving any problems.

Someone is interested in buying this system, so it's probably going to be sold next week.

I'll build a new system the week after.

I would like to get wiz's advice on attempting a hassle free oc mechanism.

I am interested in getting a low fsb c2d
then upping the fsb in a motherboard which already supports the higher fsb.
and keeping as many settings stock as possible..
ex.
take a 200 fsb c2d and take it to 266 or 333fsb
or a 266 and take it to 333
with stock voltage/hsf
on a motherboard which is already rated for 266/333

Has anyone had any luck with this type of overclock?
I am mostly confused regarding straps and what not which people keep talking about. Will have to read up on it.

My idea is a cheap processor ( i am in germany)
110 euro for a e4300 or e4400 with 2mb cache 200 fsb
and take them up to 266 or 333
whatever my mobo will let me.
so maybe 1.8 * 1.33 or 1.8*1.66
or 2*1.33 or 2* 1.66
the key is I don't want to raise stock voltages too much... can I get away with it??

Do I need to get any special type of ram to pull this off?
Or will regular pc 800/667 do?

Haven't figured out the mobo yet.
2 options, cheap route = asrock core 4 around 54 euros here.
Other option i am Contemplating is a cheap p35 mobo (around 110 euros). That way its future proof so if/when I have more cash I can pop in the next generation core.
Another reason I want to keep the mobo around is I plan to buy an oem version of win vista 64 which will get tied up to the mobo!!

Posting this here , because Wiz seems to know what he is talking about
P.S good posts , like your basic build,
Price/performance = key.
though would make default=brand new parts and secondary=open box.
Minor beef, no big deal.
Especially since I cannot get the same open box parts/prices here in germany!
I'm trying to do 3 things price/performance/future proof. I would like to eventually upgrade to a quad core once I have enough cash. I have heard the prices for the quad core will come down to sub 266 by end of july.

rajak1981 - What is your current rig? Do you have any parts to keep?

sheesh taco's give it up, stop bagging on the OP. he did a good post, the motherboard is good the psu bad everyone knows he can change that. Stop portraying the fanboy as rich said.

I have got lots of parts right from the beginning

ultra old cards geforce 1/2/3
agp gfx cards, 6800 gt
pci e cards 7800 gt
one 7950 gt
might get an 8800 gt or something next.
1 gb pc 3200 ddr ram.

I am more interested in the oc part.
In fact I am planning to build 2-3 new pcs. I am going to be using these pcs for trading workstations.
my question is not about a full rig.
I am more interested in knowhing which c2d/mobo/chipset combo is best for oc with stock settings.
I would like to raise the bus from 200-333 or 200-266 without messing around too much with multipliers or voltages.

Would using a p35 chipset help? Considering its already rated for 333? So it shouldn't need more volts or extra cooling and shouldn't be a drag??

I am not looking for extreme performance yet just a minor improvement.
I'll do the extreme overclock with the core 2 quad or core 2 quad 45 nm later when they do come out at reasonable price points.

RAM prices increase over the past few weeks.

Okay, updates anyway.

PSU still running good, the guy who bought the system is very happy with it, haven't rebooted the system for a while now according to him.

I attempted to build 2 more setups with similar rig, notice a couple problems.

Not all E4300 are capable of hitting that FSB, I got a setup that refuse to go above 322MHz FSB, and E4300's Vcore are very inconsistent, on some setups it can run perfectly fine below stock Vcore, some needs really high, as high as 1.4-1.5V to run 3GHz.

But then, all the setup I build on top of Super Talent modules are great. The 3GHz (9x333MHz) are running it on 1:1 CL4 (4-4-4-11/12) timing, and even tried running 266MHz at CL3 (3-3-3-8/9) timing, and passed memtest for over 36 hours. So, I still highly recommend these modules.

That cheap PSU is on 4 systems now, none failed so far, maybe the system is not putting enough stress on the PSU at the moment.

Anyway, after since I discover the inconsistencies in E4300, I'd highly recommend E6300/6320 over E4300, although it costs more, but I've yet to encounter any of those that wouldn't hit beyond 3GHz on stock HSF.

And by the way, eWiz had the Arctic Cooler Freezer 7 Pro going for $19.95 free shipping, don't know if they still have the deal.

And oh, by the way, I've read it on other forums that some E4300 has a FSB wall, and it could be easily countered by BSEL MOD, there are 266MHz (1066) and 333MHz (1333) BSEL MODS, that are pretty easy to perform, although I haven't tried it yet, I will give it a try when I have the time to rip everything apart.

Wiz can you please rank these processors in order of their ability to hit a higher bus speed without a new hsf. and preferably without overvolting.
Basically I am interested in knowing if intel is selling us some hidden gems .
Can you also tell me whether there is any significant difference in stock hsf which comes with all these different processors?

I wouldn't want to buy such a slow core that it comes with a stock hsf that is half the quality of the higher end c2d.
For instance if it is true that we can take a 6300 @ 266 (which costs 150) to 333 fsb without significantly overvolting then we effectively have a e6550 which costs 193..
If we do the same for a 6400 (cost 169 here in germany)
it goes and becomes 6750 which costs 221 here.
and finally if we can overclock the e6600 it goes from being a 2.4ghz 209 euro processor to a e6850 which is a 3ghz 304 euro processor
Also another nice thing about the q6600 would be that even if I get stuck at stock 2.4 ghz its not too slow a cpu . I could live with it.
I am not too interested in overvolting to start off the overclock.
If intel's binning process is efficient then there really should be no such easy overclocks for people like me. If however intel is churning out higher quality cores then maybe there is room for a free overclock.

Kindly reccomend the best pick among these candidates
Reward = gain in $ (if chip overclocks to higher level)
risk= cpu dies?? but the risk is only there if we significantly overvolt?
I suspect without overvolting the risk to the processor would be very near 0?

Basically I am looking for an expert to rank the outcomes in order of probability.
I do know that if we were to do something simple like just raising the fsb it would be one of the easiest overclocks.
I remember doing something like this with old celerons a very very long time ago.

Not true as the E2140 is cheaper at around $81. Its a 1MB C2D that doesnt perform as well at the same clocks as the 2 and 4MB versions. The E2140 does require 3.1~3.2GHz to match the performance of the X6800.

I hear it can OC to 3.6GHz on air.

I can't tell which overclocks best, because I build only systems that are best bang for the bucks. People around this forums, and people in real life that I know, know me very well that I build cheap systems, and overclock every single juice out of them. So far, I could only tell for E4300, E6300, E6320. Anyway, E6300/E6320 are more consistent in terms of overclocking, because it has soldered IHS (Integrated Heat Spreader).

As for the cheapest C2D, at the time this guide was written, E4300 was the cheapest on the market. I don't know how well the E2xxx overclock, but I may soon build a system based on that.

The best bang for the buck for whom? Not for gamers thats for sure. This would be a nice business/home office build.

In gaming where the GPU is the king your best with the cheapest dual core and the best GPU. Even memory takes a second seat to the GPU in most all games. At 1280X1024 your system will start taking a beating from a cheaper dual core and a better GPU.

This is a X2 3800+, 1GB of RAM, and a 8800GTX v/s an E6600, 2GB's of Ram, and 8800GTS. Im not trying to put down Intel here just saying a better build is the cheaper CPU E2140 and a $30 better GPU for gamers.

It has been emphasized many times, if you want a gaming system, go for better graphics card.

Today's CPU has more than enough juice to power up the most demanding game in the industry, but graphics card haven't really live up to the standard yet.

This system I recommended is best bang for the buck for the overall user, who doesn't want to sacrifice CPU power for Graphics, and vice versa.

Again, I don't know how well the E2xxx overclock, but will build a system based on that soon, but before I do that, I need to read more reviews on that.
