Just added a E8600 3.33 and want to overclock

[AddRAM]

XFX 750i overclocking enabled. I`m just not coming up with the right #s for the fsb to push it to 3.6. The multipliers are different from my E8200 so it`s confusing me. Help Please

 

[TwoCables]

Oh, you upgraded from an E8200. Now I know why your multiplier is sitting at x8.0.

I'd be careful overclocking with the PSU you have. I've never heard anything good about it. I'm sorry, but I know that I would want to know.

 

[AddRAM]

I need fsb #s to try.

The multiplier is jumping all over the place 6, 8 , 10 .

I'm not comfortable trying to overclock with this PSU powering your system (the LSP unit). If this particular PSU fails due to overclocking, it could kill something in your system, or even your entire system. At the very least, it will probably make both overclocking and achieving stability noticeably difficult.

Still, disable C1E (or Enhanced C1E, or whatever it's called in this BIOS), and disable Enhanced Intel SpeedStep Technology to get started so that it stops dynamically adjusting the multiplier like that.

To calculate what your overclock will be based on the FSB, divide by 4 and multiply by 10. For example: 1333 divided by 4 multiplied by 10 is 3.33 GHz (you may need to do some minor rounding).

Ya i have to go in and figure that out. I wil be happy with the 3.33 GHz if I can get it to stay there.

 

[TwoCables]

Oh man, I don't know if I would attempt any overclocking at all because if I go by this, then you're already cutting it very close at stock:

Their power supply pulled 396W from the wall outlet with two 9600 GTs running Oblivion at 2560 x 1600. If their PSU was 80% efficient during this power draw, then their system was pulling 316W from the PSU during this test!

Your PSU has a +12V capacity of 360W. Here's a breakdown of how a PSU's power is distrubuted:

On PSU Voltages

So really, I think you're in need of a larger +12V capacity, not to mention a higher quality PSU. This PSU is actually a low-quality unit and with a +12V capacity of 360W, it's really just a low-quality 400W PSU. It doesn't look like a safe situation for any overclocking to me, I'm sorry.

The Ultra 550 LSP is that bad ?

My next upgrade is the Corsair AX or HX 750


I at least want to get the E8600 functioning properly at 3.33 GHz

Oh, then all you have to do is change the multiplier to 10. If you want to overclock, then it would be beneficial to disable C1E and Enhanced Intel SpeedStep Technology because these two features can get in the way of overclocking for technical reasons I don't know how to explain. When staying at stock, they should be enabled so that the CPU can do what it's designed to do properly.

As long as the multiplier is at 10, everything will work perfectly and you will never see or feel a performance loss due to the dynamic changes you're seeing which are enabled by having C1E and Enhanced Intel SpeedStep Technology turned on.

The Ultra 550 LSP is that bad ?

Yeah.

It's probably ok if you don't overclock, but it's still not delivering clean and stable power which has the chance of being a little bit harmful in the long run.

 

[AddRAM]

If I turn off speed step and set it to 10, I get a blue screen after windows boots up. If I chang it to 8 it boots up ok but i still get this in cpuz.

But I still get this result with this gadget.

 

[TwoCables]

That gadget is not showing the actual clock speed. It's just telling you that it's supposed to be a 3.33 GHz CPU. CPU-Z is telling you what's really going on, and it's showing that you have a multiplier of 8. Multiply 8 by 333 and you get 2,664 which is 2.66 GHz which is exactly what your E8200 was at. The E8200 has a FSB of 333 and a multiplier of 8.

This BSOD could be the result of not enough power. I'm not sure. Try leaving both C1E and Enhanced Intel SpeedStep Technology enabled and only change the multiplier to 10.

 

[AddRAM]

No, the top clocck on the gadget fluctuates just like cpuz right now it`s at 2001 MHz. Showi.n the same as cpuz

I set speed step to enabled and have the multiplier at 10 and cpuz goes nuts, is the a bad cpu or something ?

So if I step up my power supply to the HX750 will I be able to turn off speed stepping and not get a blue screen ?

I can`t believe this power supply can`t push this small upgrade of a chip.

What do you mean by "goes nuts"? It's supposed to fluctuate dynamically based on the loading conditions. The latest version of CPU-Z has a much more accurate engine. If you were to use a much older version of CPU-Z, then you wouldn't get to see what's actually going on. CPUs are naturally far less "stable" in this sense than we have all been led to believe by programs like CPU-Z. They never stop fluctuating because they can't. I'm not sure how to explain it though.

I can`t believe this power supply can`t push this small upgrade of a chip.

It may have already been cutting it way too close, and so the E8600 might be just sending it over the edge. That is, if it's even the PSU. Although, I'm limited in that I don't know what else it could be.

So if I step up my power supply to the HX750 will I be able to turn off speed stepping and not get a blue screen ?

If it's the PSU, you wouldn't have to get the HX750. A perfect fit for your system would be about a 550W PSU (a quality-made unit of course). Even a 450W would be alright, so 550W isn't the minimum.

But it`s an Ultra LSP 550 Pro Lifetime Series with 30 amps on the +12v rail. It`a a piece of junk ? It`s brand new and works flawlessly.

And it finally bumped up the cpu score from 6.3 to 6.7 .

Yep, and this PSU is pretty much no good. Don't expect it to last longer than 1-2 years. You might get 3 out of it if you're lucky.

I hate talking like this, but again, I know that I would want to know.

Ok I` believe you. I`ll have to have to have a word with Ultra. Are all their power supplies bad ? I`ve had 3 and they all have lasted a long time.

I'm personally not sure. Although, in my 4+ years on Overclock.net (about 18 hours per day sadly), I've never seen anyone say anything good about Ultra's PSUs. I don't know if that means they're all bad, but it tells me that I will never recommend any of them. I have learned, however, that this particular PSU is pretty low in quality and should usually be avoided - especially if you want to overclock anything. To be very honest, I had to ask about it just to be sure.

Ultra just isn't a good brand for PSUs (although, I don't go just by brand names).

 

[AddRAM]

Would this be better ?

[TwoCables]

It's major overkill, but yeah.

This would be more than enough and it costs less:

SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

Corsair used the SeaSonic G Series to create their Gold-rated HX series.

I wanted to find something cheaper like the one below, but the price difference isn't enough to justify recommending it:

Rosewill CAPSTONE Series CAPSTONE-450-M 450W ATX12V v2.31 & EPS12V v2.92 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

It's only $4.01 cheaper after shipping, although it's a high-quality modular PSU.

 

[AddRAM]

Dam, then I`ll just come down to the HX650.

CORSAIR HX series HX650 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

CORSAIR HX series HX650 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com

If it absolutely must be a 650W power supply (no need, not even for two GTX 680s), then don't get the HX650 because there are other high-quality 650W PSUs that have better connectivity. Newegg's site is wrong: the HX650 only has 2 x 6+2-pin PCI-E cables, not 4 (I had to check Corsair's site one day because someone told me about it).

So, here's a PSU that's just as good (if not better), it costs less, and it has 4 x 6+2-pin PCI-E cables:
