As far as I can see there seems very little gain over a single drive to having two 150GB Raptors in RAID. Not that I mind much because I couldn't afford that anyway. I found out the drive with the LEDs was an external one, something like a 250GB USB2/IEEE affair instead, and since I'd prefer a long-life drive, would definitely be buying the normal 150 raptor instead. 1.2Million hours is a lot, that's 24 hours a day for 50,000 days (15 1/2 years!)

Actually the old slow small raptors already saturated the Sata150.
I just have a couple of 80gig Seagates.

The new Raptors are double the speed of the 36 gig Raptors so they would be easily able to tap out the 300 standard.
SCSI surpassed this some time ago with 320 MBs per channel. But SCSI raid is so costly that only the the biggest companies can afford the huge arrays.

Go here to ask your build questions. http://forums.afterdawn.com/thread_view.cfm/302283
Same people and it's geared toward questions on building and performance.
I noticed the OC you did was a moderate 10% and the Northwood is known to be one of Intel's cooler chips. Other than finding one on a good sale or used, they're still quite pricey. Dell and some other vendors had the 3.4 priced around $700. StarMicro, who I suspect is selling "pulled" CPUs has the Extreme for $900. I've not even seen one of those offered anywhere else. But back to the point, it doesn't take a lot of cooling to keep a cool running CPU tamed. Though the AMDs are noted to be cool running, when they're OC(ed), they will get hot. In fact the top end AMDs such as the 940 Socket Dual-Core Opteron 280 Italy is said to be on the hot side. On that I'm just going by owner reviews, I can't afford one. ;)

I'm hardly surprised. But overclocking the fastest processor in the range doesn't make a great deal of sense. You'd only be buying the top-end model if you didn't want to overclock really, unless you wanted to keep the warranty and then squeeze out the last few mhz. I'll be doing that with the X2 4200, but of course that has far more headroom after the warranty expires.

I think that if someone is just looking for an easy overclock then the Opteron 180 has the advantage of a higher clock multiplier which means that juggling memory and HT settings won't be an issue when overclocking to 2.6 Ghz. and it still offers values since it is essential a highe quality fx60
That being said, most overclcockers go for the 2.2 Ghz chips because they offer flexiblity and they fall right in the middle for price.
That list includes the X2 4200, X2 4400, and the Opteron 175. I chose the Opteron 175 for its server quality performance and overclockability, but that's just me and I can afford it. If I was on more of a budget then the X2 4200 would have been my choice becasue the X2 4400 is too close to the Opteron's 175 price and the X2 3800 would mean sacrificing memory speed.

What is the fastest CPU today will be one of the slower ones tomorrow but hopefully at least a couple of years from now. LOL
If you start with the fastest, doing a 10% O/C is nothing, going to 20% is taking it to it?s stable limits and beyond that it?s the Freezer being attached to the chip!
If you have an FX60 @ 2.6 to start with and a 1.30 voltage you should have the room to take it to 3.12 and be stable. Why do it? Because you can. :)

Those are good scores when used as indicators but I think that when measuring hard disk performance Sisoft doesn't measure broadly enough to be considred viable. Tech sites tend to use it for CPU and Memory measures but never for multi media or file system measures.

I took my Venice core to 20% completely stable and with great temps. You've been in the Intel camp for too long.

@Sophocles, my point exactly when addressing the FX60!
My Northwood 3.4 doesn't like going past 15%, not as a heating issue, just a stability issue. My 2.8 Northwood is very comfortable at a 20% O/C. And if I recall correctly your Opteron 175 seems to like being near the 20% as well. Stable to me means NEVER having a problem, not just every once in a while having a glitch. So by my statement, going to a 20% O/C should be just fine with the FX60.
I am not a Prescott user... <G> so I never had heat issues.

Actually it makes as much sense as OC(ing) any other processor. If it's OC(able) then there are still performance gains to be had. And Intel didn't appear to make all their CPUs equal. The 3.4 N I have has some differences from the 2.8 N. Maybe Sophocles can shed some light on the Northwoods as he has one. The pin side of the processor has what looks to be transistors on the outer surface. The 3.4 has more of those than the 2.8. I'm not sure what's going on there. But back to OC(ing), besides the performance, the biggest reason is just because we can.
The Northwoods are no big problem as far as heat is concerned. Setting a 3.4 to about 3.8GHz is barely over 10%. No need to even up the cooling if a person already has a good heatsink and fan. ScubaBud has already shown that. I'm just waiting for theonejrs to start seeing where he can push one with his test setup. He was wondering where he could get one and I pointed out a cheap vendor. He already has the big Zalman cooler to help keep the temps under control. I'm wondering if 20% would be pushing a 3.4 too far on air (4.08GHz). Scubabud said his was stable at 15% (3.91GHz).

I'm betting that the FX60 can't get much higher than 2.75 and if that, because it's closer to the cores maximum already. The FX60 is using the Toledo core but I'm betting that it was binned to Opteron standards. Many believe that the reason that AMD is discontinuing the 939 Opterons is because they're affecting the X2 and ultimately the FX60 sales.

ScubaBud,
What RAM are you using with your 3.4 Northwood system?

I'm sure it would but no more money will be spent on this system. Below was a Sandra memory test a while back:

Kingston is ok as long as you don't push it to far and it seems to be doing Okay with scuba's system..
My tastes usually have me running OCZ or Corsair.

I can forsee OCing an FX60 far being difficult, they're the top end CPUs. If they could all comfortably achieve a higher clock rate on air cooling, AMD would do so and market the FX62 now. Anyway, we malign the Prescott core for running hot, but isn't the Gallatin the worst offender?

This article took the FX60 to 3.2 stable. Other articles that I've read took it to 2.9 stable very easily. Each using different memory and different motherboards. All using the stock heatsink and fan.

It's advantage is in it's clock multiplier, I'll have to read more of the review before forming a conclusion but if you notice, the HT is only 230 to get to 2.9 GHz. Mine is at 267 times 10 to get to 267 Mhz. If I multiplied 267 times his clock multiplier 0f 13.5 I would be hitting 3.6 ghz. I'm a little suspicious of the highend numbers such as 3.2 ghz as being completely stable but I'm always open to possibilities and always open to faster machines but within reason (sometimes).

So far the only thing I ordered was the WD 150 Raptor. I'll use it in this machine for now. After reading more it seems that DDR2 might be on the horizon real soon for AMD.

DDR2 is basically a hand-in-hand with Socket AM2 which is coming out in summer, around the time I planned to get the new computer. Hmmmm. I can't help but wonder if it might be worth waiting for that.

I tend to agree now. Doing another Sandra test on my PC shows I'm currently near the same or better than an FX57 single core. It's the double core's that can eat my lunch in the Dhrystone test but the not necessarily so in the Whetstone test. I am going to hold off, (once again,) until I see which way AMD goes with DDR2 or as one article said, maybe even DDR3. Either way motherboard changes and more then likely socket changes will follow so I don?t want to make the same mistake I did when the Pentium Pro came out, then 6 months later they were obsolete! Back then with SCSI drives it was a bargain at nearly $5,000. Not to mention adding a Barracuda SCSI 9 gig for a mere $2,200.

See this is difficult for me to imagine as the oldest computer I really got to know in detail was only 6 years ago, so relatively modern technology - It came with a 13GB ATA100 (i think it was, possibly 66) hard disk as standard, which was quite reasonable.

Here is my single core AMD 3500+ overclocked, note the FX57.
Now imagine what an FX57 can do in the right hands. LOL
