Northwood 2.8...overclock???

[Platform]

How far can you clock an Nothwood 2.8 with stock cooling :confused: if possible.........has to be stable for everyday use ;)

And if possible..........how

:confused: :confused:

Thanks

System in sig.......if anything else "info" is needed just say ;)

[Andrewv]

im stable on 235mhz x14 (3290mhz) benchable on 246mhz (bad memory :( )

with good mem you can be stable at 250mhz with air cooling and try to get 3.6ghz

[Poki]

I had a 2.26 northwood that did 3.8 on stock cooling... You can never tell how far they'll go. I think your board will be the limiting factor if you have an exceptional chip.

[=[PULSAR]=]

What is the stepping in CPU-Z?

[Platform]

=']What is the stepping in CPU-Z?

The steeping is 9 in CPU-Z

Thanks for the info people....don't want to spend money on new cooler.....dont need Ghz OC but something like 3-3.2Ghz :p: Needs to be stable and not too hot.

Since what it seems I need to do is raise the FSB.......how do I do that :confused: :confused: Sorry new to this OC thing :(

[ibby]

ive had 2 2.8 northwoods.
both stopped at 3.35 gig at 1.675 v

[GOZ]

at 3.5 here 3.6 is alittle to warm for me, I like things cool

i hope you mean 200-400mhz more, you can obtain this in the bios by adjusting your fsb, just make sure your ram can handle it and you lock your PCI/AGP bus so you dont run into any problems there.

Don't know how you got just 200-400Mhz......but whatever :p:

How do I know if my RAM can handle it...Kingston PC 3200 2x256MB
And if I'm not incorrect I also lock the PCI/AGP bus in the BIOS :confused: :confused: Also what about Vcore voltage????

Thanks

[ibby]

lock the pci /agp in bios.
push the fsb to 205
and then use stock core voltage
reboot
and test for stability

If it`s Kingston value ram your using you wont get more than a 200mhz overclock anyways.

Buy some good ram, like OCZ gold pc3700, or pc4000.

With decent ram you should be able to clock to 3.3 or 3.4 without even touching the voltage.

more voltage = more heat

[MrSeanKon]

Don't increase Vcore above 1.600 Volts (in my opinion)... :)
Intels are sensitive processors... :D
Well it depends....
At least you should achieve 3.2 - 3.3GHz..
Your RAM needs divider at high FSBs..

Yes it is value
:mad:

But what would that high clocked RAM do.........my mobo only takes DDR400 Max :confused: :confused:

[IYP]

at 1:1 you need it to be the same as the FSB....so raise the fsb and you raise the ram

[Rocket]

Yes it is value
:mad:

But what would that high clocked RAM do.........my mobo only takes DDR400 Max :confused: :confused:

Thats what almost all motherboard packaging say...."DDR400 max"

DDR400 is 200 on the FSB
To overclock you need to raise this number.

eg: raised to 233 gives you 3262mhz @1:1

Thats why I suggest OCZ gold PC3700 "DDR466"
You can get at least 3262mhz without going over ram speed.

It can be bought fairly cheap and this ram itself overclocks very well.

I`ve had OCZ gold PC3700 to 534mhz @1:1 on my machine.
which is 2.8E @ 3750mhz

[Rocket]

btw The kingston value ram I had would never overclock more than 200mhz....even with a divider. :nono:

[Lithan]

I agree. Northwood seem to be safe as long as you stay under 1.7vcore. I know dozens of people who experienced SNDS and all were running 1.7vcore+. I never risked it, so I don't know if it's fixed now or if people just stopped trying to run at 1.7vcore for any length of time. On stock cooling I wouldn't go over 1.625vcore actual. But really, it all depends on your temps. If your temps are fine, hell try 1.65-1.675 and see if you gain anything.

[deltarealm]

Gallatin northwood EE will handle 1.7v+ no problem, so why not a regular northwood. Does the EE version actually use the higher voltage to feed its 3 times the amount of transistors over a standard northwood?

[Platform]

CpuFSB, SoftFSB and SetFSB

Are those programs any good.......what do they do :confused: :confused:

Edit: Some look to be very........just click and see what happens :rolleyes:

SetFSB seems OK to me or?????????

[Liquid3D]

The most stable overclocks are usually done through the BIOS. It's there you have full control over system (motherboard) hardware settings. Be sure you LOCK PCI/AGP buses 33/66Mhz respectively. Then raise FSB but to keep things simple go into your Advanced Chipset Features and set memory to SPD (Serial Presence Detect) this allows the BIOS to run the memory by manufacturer's pre-set timings, of which there are usually several. You can always go back and tighten latencies later. Avoid voltage adjustments until you can't post, then increase voltages by the lowest increment until the system does post. The trick is to determine where that voltage is needed? So you may want to try VDIMM before VCORE. If VDIMM doesn't work raise it more, if that doesn't work, set it back to default and raise Vcore. As you go higher on the FSB eventually the memory will require VDIMM, Latency adjustment (loosening) and/or vice-versa.

THIS (http://dlsvr03.asus.com/pub/ASUS/mb/sock478/p4p800/Aibooster_v1_01_13.zip) utility will give you full over:banana::banana::banana::banana:ing potential from within Windows. If your going to use a software based utility eschew SoftFSB or similiar utilities and use Asus. It also gives you basic info such as Clock speed and I believe temps. Clicking above gives direct download link to these, just Save, Open and Install.

You also may want to flash your BIOS it's likely newer BIOS versions may have better overclocking abilities.

If you do want to try a software ultility the best (IMO) is ClockGen here is the link to CG-ICS952607 (http://www.cpuid.org/download/CG/CG-ICS952607.zip) which is the version for your PLL or rather for your Asus P4P800 Deluxe

I would say in your situation memory will hold you back then heat will be the next hurdle. If your staying with stock cooling don't expect to reach 3.5GHz right off the bat. It's possible, anything is, but it depends on the stepping of your chip. You can loosen the latencies on your memory if their manually set. This will give you some more overclocking headroom if in fact memory latency is a factor. Lets say you go into Advanced Chipset Features Menu and your memory is running at CL2-2-2-6 (which I doubt) changing it to 2.5-3-3-7 or 3-4-4-8 would give you more headroom as well as raising the VDIMM might. The OC-purest' will seek to find his/her CPU's max frequency ceiling at default voltages, that's when your truly exploiting the manufacturing process. Remember there's no architectual difference between a 2.4C and 3.0C (130nm process core for example) their simply binned based on a specific set of criteria such as voltage, or heat at such and such speed / voltage, but often a 2.4C will clock just as high as a 3.0C or even higher.

To reiterate: Raise frequency 1st until the system won't boot at that speed, then THEN raise voltage (Vcdore) by the smallest increment until that frequency takes. Don't simply ramp up voltages (any voltages like Vcore, VDIMM, chipset etc.) along with frequency because you'll confound the process and the heat. Loosening RAM timmings will also help when raising the FSB if your memory seems to hold you back. Then combine loosening latencies with raising VDIMM, and Chipset, etc.

Thank you VERY much for all that great info :D ;)
But could you say which one of these programs you would use.......except BIOS :p: tried Clockegen....nice...but does that do the RAM :confused:

[Platform]

Well using AiBooster I get my CPU fan speed to be 1854rpm at default and 37c

If you use the overclocking feature in AiBooster......does that take care of the RAM or because in the user guide and the program does not mention it???

If an overclock.......should I increase the CPU fans speed.......I have 2 fans in my case drawing cool air in and one exhaust fan running at 2000-+ rpm..and my PSU has 3.

[Liquid3D]

First I always put fans at thier highest settings when overclocking, in fact rarely will I use the fan control software. I either get larger fans (larger blade's move more air, hence can spin slower and are more quiet) 120mm on everything (even the heatsink except I use H20) or go H20. H20 system are now so inexpensive, so quiet, so reliable and so easy to maintain air is really becoming obsolete (although ultimately your always cooling with air because the radiator uses fans to move AIR to cool the water). Thing is with a decent watercooling system you can constantly keep your CPU near the ambeint temperature of the room. Of course without adding additional energy (active cooling: compressor, phase-change etc) you can't cool below the ambeint temp. Nonetheless 22C ~ 25C is a heck of a lot better then 37C or 48C. This site (http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html) is invaluable for learning about the basic physics of thermodymanics.

In so far as SOFTWARE-overclocking, I always do my overclocking through the BIOS. I rarely, if ever use Aibooster except to record temps and other data such as CPU speed for reviews. This is because so many overclocking programs which work through the Operating System are then misread by other programs which monitor your system specs. For example if you download and install both CPUZ v.1.29 (http://www.cpuid.org/download/cpu-z-129.zip) and WCPUID (http://cgi2.tky.3web.ne.jp/~nrklv/cgi-bin/softdl.cgi?wcpu330.exe) then overclock using ClockGen or similar you'll find that CPUz reads the clock speed correctly after you've changed it in Windows but WCPUID reads it incorrectly. SiSoftware SANDRA 2005 (http://www.sisoftware.net/index.html?dir=dload&location=sware_dl_3264&langx=en&a=) may read it incorrectly too when you overclock using software.

Here's a test: boot up at default speeds and voltages and run Sandra Memory Bandwidth and check your CPU speed by using CPU-z and WCPUID.

Then overclock using the ClockGen and run SiSoftware Sandra Memory bandwidth benchmark again. Also run WCPUID and CPU-z. You'll probably see the only program that accurately recorsds the changes when overclocking through Windows will be CPU-z.

AiBooster is better because as far as I recall it asks to re-boot once you've entered the changes meaning it's then making those changes in the BIOS. Thye call it Ai becuase it's truly more intelligent and YES it does change latencies and even memory voltages as far as I recall. In this respect the program is bettre then many. It basically has a series of preset BIOS settings based upon what changes you make in the software. Programers simply took hundreds of overclocking scenarios and pre-programed them inot the software so when you choose an overclock setting it has sveral option to choose from. You can also choose to tweak your system by memory latencies, frequencies, and percentage 5% overclock, 10% overclock etc. This program is decent but if you rely on it to much you won't learn anything. For example I'd use that software then check what changes it makes at certain speeds. You can actually learn to overclock by noting what AiBooster does based on certain features it offers. Then you can make your own improvements (like trying to tighten latencies a little more) by doing it yourself in the BIOS. The best way to learn is to ask, and then to try.

It's pretty simple, based on your hardware (CPU type binning, memory IC's type, binning) there are certain performance speed and such you can acheive and then there are limites usualy based on heat. If your memory is rated at CL2.5-3-3-7 it's possible it may run at CL2-3-2-6 and if it doesn't then you can try that same setting except increasing the VDIMM. Keep increasing it until it does work. BUT some memory chips simply won't run any tighter latencies, but that doesn't mean they won't run any faster. In fact since there's only a certain number of memory chips manufactured and then used for all the different memory brands and models on the market, all you have to do is find your memory's performance parameters. If it won't run tighter latencies, then try higher speeds, if it doesn't run higher speeds give it a little more voltage. Always try to overclock without using voltage, then try voltage in small increments only as a last resort. This method allows you to find your maximum speeds and performance while always keeping heat at a minimum. it also ensures your hadrware will last MUCH longer.

As far as software based programs I honestly don't use them to overclock. But the one I feel works best is ClockGen although that only changes frequencies not latencies. Remember in Clock Gen HTT = Memory speed.

Also remember if in your BIOS your running your memory on SPD (Serial Presence Detect (it may also be called Auto depending on the BIOS)) as you raise the FSB, hence memory frequency, your latencies will loosen up. You can check this by setting the memory to SPD in the BIOS rasing the FSB and then checking the lantencies by running CPUz and cklicking on the memory tab as you'll see below in the screenshot.

Below you'll see I'm running some Corsair 5400UL DDR2 on an Asus P5AD2E-Premium at 284FSB using a Pentium 630. The chip overclocks to this speed without having to raise Vcore, this is the lower multiplier setting available on newer Pentyiums they give you the lowest 14x (2.8GHz) and whichever your model is. My 630 is a 3.0GHz CPU so 15x200FSB = 3.0GHz. Thye did this I belaive to help take advantage of DDR2's high speeds. This appeals to overclocker's as well, but I'm sureb the primary reason is to allow their CPU's to fully explaoit a standard THEY pushed onto the market DDR2. Anyway I'm running the chip at 14x284FSB because I'm only looking to run the memory to 300FSb not get the higheest overclock. This chip will however do 15x285FSB at default Vcore.

Anyway notice how 14x284 is read correctly by CPU-z at 3.9GHz but is displayed as 4.2GHz both by AiBooster and WCPUID, and it even says in the AiBooster display 14x 284. This is a deeper problem because I actually overclocked this through the BIOS. But anyway things like this happen much more frequently when overclocking with software. If you want anymore help just eMail me at keithjsuppe@hotmail.com I'm moving this weekend but will be hanging out on the forum much more now. If you want to see how I've overclocjked some memory and a pretty informative review I've written check this out it talks alot about overclocking and overclocking software;

Well, some of the 2,4C's were able to reach ~3,6Ghz stable with stock cooling and stock volts. The 2.8C's I believe are not as good OC'ers, but If I'm correct, 250FSB should be stable. 200x14=2800, 250x14=3500Mhz. And set memory multiplier to 4:3(?). Well I'm not shure what the multiplier was, but the memory speed with 250FSB was 200Mhz(DDR400).

But if you realy want all the performace, look for some DDR500 RAM.

The CPu might require mroe volts, but there's a big chance it will work well without more. I'm not shure if that's the case, but there was in the very star a model of P4C @3.6Ghz. Later they decided not to make such models, yields were low or something. But some of the already made were probably downlocked to 2.4C, 2.8C. So it's no wander than moust 2.4C's are capable of 3.2Ghz stable with stock volts. 2.8C is a guess, but might turn out true.

I remeber a completly stable 2.4C@3.6Ghz @ stock volts @ overclockers.ru wich they used to use to bench video cards, etc.

But you never know before you try :fact: .

[Liquid3D]

That's absolutely true. This statement is indicative of that area of Overcloking where those of use like to call ourselves "Overclocking Purist's."

The difference between a Purist approach and all others is, we would purchase such and such a CPU model usually the lowest model number or speed from a specific core design, and then find that CPU's highest speed WITHOUT adjusting Vcore. This not only exploits the manufacturing process allowing the CPU to perform on par with the "Flagship" in that line, but surpassing those clock-speeds allows the overclocker to effectively own the fastest CPU "un-available" to anyone except fellow overclocker's.
