Are newer 45nm LGA775 CPUs more Overclockable?

[Doltmoopsie]

Are newer 2011, 45nm LGA775 CPUs more Overclock-able then the 2008 parts?

I have a Pentium E5200 from 2008, it does not overclock well (can't hit 3.33Ghz at safe voltages). I have been considering buying another LGA775 CPU while I wait for Ivy Bridge to come out. The Pentium Dual-Core E5400, E5700, E5800, etc. are all under $100.

Should I expect that I can hit 4Ghz+ with normal voltages and a new (2011) E5400+ ?

Should I just "burn" the current E5200 (2008) with 1.4+ volts?

What could you do with a 4GHz E5x00 that you can't do with your current E5200?

How do you know you'll get a 2011 E5400? It could have been sitting on the shelf for over a year.

 

[LOL_Wut_Axel]

LOL. It's probably your motherboard. Everyone I know and all of the reviews were able to get 3.8-4GHz out of the Pentium E5200.

Also, there's no guarantee you'll get a new chip when you buy an E5400. It could've easily been stored for a year, as the member above me said.

You want something decent that'll hold you out until next year for $100, try to get a cheap used Q8000 series CPU, preferably a Q8300 or Q8400. Don't get the Q8200; it's a bad OCer. If you get a dual-core, clock-for-clock you're only looking at 10% improvements for E8000. In multi-threaded apps a Q8300 at the same clocks you are now should be 40-50% faster.

 

[RussianSensation]

I vote none of those options. If you really need an upgrade, then get a 2500k and be done with it. Ivy isn't out until late March of 2012. That's a long time to wait. Also, going from E5200 to 2500k is going to be a massive difference. I doubt Ivy is going to be that much better than a 2500k @ 4.5ghz. Also, with that logic when Ivy ships, we'll probably be 12-15 months away from Haswell, which will spank it. In other words, there is little point in waiting.

Maybe your memory is holding you back. Is your memory overclocked?

What can you do with a Mazda RX-8 that you can't do with a Toyota Yaris?

Take turns at much harder angles, accelerate faster, autocross, etc. etc. A shit load of fun too.

But you have to be into doing that. If you will drive the RX-8 exactly like you will drive a Yaris, and maintain the car within the limits of what the Yaris can handle, then, at most, you'll just be graced with a nicer looking car (and potentially a manual transmission if you made the right decision...)

If everything you do right now is handled perfectly fine, what is the incentive to upgrade? To put it a better way: if the games that you play all give you 100+ fps, why upgrade?

Is there a game you tried that you WANT to play that is giving you <30/60 FPS and you know the bottleneck is the cpu? Do you encode all day long and could benefit from a faster cpu? Are you dealing with crazy simulation programs that each up all the cpu cycles they can get? Do you partake in distributed computing? Is there any application you use enough that a speed boost from the CPU will make a more pleasurable experience?

It is questions like this that truly help to decide whether or not you should spend more money now to upgrade a CPU.

burn more gas while getting from point A to point B no faster if obeying the law and being less comfortable while carrying more than 2 persons and/or luggage?

Some people buy cars for more than just getting from one point to the other, you know. Some people actually care about having something that's fun to drive.


Anyway, we should stop derailing this thread further. This thread is about CPUs, not cars.

This.

I upgraded a friend's rig with an E5200, when they first came out, and he was able to hit 3.75Ghz, on 1.42v (1.4v CPU-Z under load). IP35-E mobo.

Unfortunately, he stopped doing SoB for me, so his computer wasn't loaded anymore, so the vcore bumped up to 1.42 at idle, and the CPU degraded over a few years. It's currently clocked at 3.5, after lowering to 3.65 first. CPU degraded that much. So don't burn your E5200 with 1.4v+, it won't last.

which is exactly what I was doing...illustrating the fallacy of car analogies, even when done correctly (of which this one was waaayyy off) they're still foolish

 

[sm625]

If a 3.3GHz E5200 isnt fast enough, then you're probably sensing a need for more cores rather than a need for more speed. Any quad will produce very noticable improvments. A faster dual core wont get you anything you can feel, unless it has 6MB of cache. (And thats hella expensive.)

lol @ the "buy a 2500k" crap.

 

[richierich1212]

@ sm635: nice sig, lol.

 

[formulav8]

My e5200 couldn't get near 3.8-4ghz. Thats definitely not even close to a common oc. I was able to get it stable @ 3.3ghz with a couple bumps in voltage. Just run it at 3.3ghz if you can do it at a safe voltage.

Would help if we knew what OP has for a motherboard. As previous posters have pointed out, this could limit a lot of CPUs' potential.

I have a Gigabyte EP45-UD3P (rev. 1.1) and my memory is 4GB DDR2-800 by Crucial. Power supply is the fan-tasticly quiet Corsair vx450w, that produces only 21 decibels.

All voltages but VCore have been Stock (not BIOS default of Auto). I have not been using any overclock on the memory.

 

[Spikesoldier]

What FSB speed and multiplier are you using?

 

[betasub]

That P45 should give you FSB options up around 500 - much better than my P35 board that got flakey at anything above FSB400. But check your memory divider/multiplier options: that DDR2-800 may limit you unless the BIOS has a ratio to underclock it.

 

[ed29a]

What can you do with a Mazda RX-8 that you can't do with a Toyota Yaris?

I see what you did there ...

But I was wondering exactly about that... Considering that speed limit is around 100km/h here on highways, both cars get to 100km/h easy. I guess RX-8 is probably more of a chick magnet compared to the Yaris so that's pretty much the only difference, and the price.

I had some P31 boards that had trouble with FSB400 too. Then I got a P41, and it has trouble with FSB350! :\ I thought the P4x series used roughly the same chips. So it might be your board at that. Or maybe I'm confused.

lol @ the "buy a 2500k" crap.

Actually, he has a point. Not a 2500K, of course; but remember that the OP is looking for Ivy Bridge, which can plug in to the same board as SB chips. So if you're willing to buy the motherboard and RAM now instead of later, you could go with an i3 2100 or the like now, for a little over $100, and trade straight up to Ivy Bridge later.

To get any speed you need large cache and fast fsb and memory.

Rev to 9000?

On to the thread - Quad core or save the money for a small upgrade. As others have said, it's likely the motherboard holding you back.

But isn't 1.4V safe enough for 45nm chips?
