Hi :)

I placed an order last night for the following:

Core 2 Duo E6600
Zalman CNPS9700 LED cooler
ASUS P5W DH Deluxe
X 4 OCZ (OCZ2A8002GK) 1Gb PC2-6400 DDR2-800 4-4-4-12 ATI Certfified ( so 4 GB in total )

I was not considering overclocking it at first until I inadvertently saw a few threads on it. I sort of jumped the gun by ordering the Zalman cooler later that evening. But is that enough to get it to maybe 3ghz? I dont wanna go too crazy really as the pc will be used a lot. Ive tried to read up on this more before posting but i see people are reducing the performance of their ram to enable overclocking of the cpu. Would I need to do that to make 3ghz? or am I getting the wrong end of the stick here?

I'm upgrading from a Athlon XP 3000 32bit, asus a7n8x delux, and i have built many basic machines for friends, family ect so I'm fairly confident with some of the jargon. Just not tried overclocking before.

I think what I'm trying to say is have I bought a good enough group of components to overclock. And what would you do in my shoes? Am I better off just leaving it stock?

I know I should of asked all this before actually purchasing it all but I'm afraid that's the way I am lol.

Thanks so much for your time and you help is much appreciated.
 
"Am I better off just leaving it stock? "

Thats just only up to you ! OC is a mine field and often relates to luck than to anything else ... but if do it by the book and in small steps it wont hurt u'r sistem ... will just improve him. So ... during the time till ur stuff arrives , start reading and gather as much knowledge as u can. A good place to start is Wusy's Guide for Core 2 duo
 
Ah ok so i see that you must lower the ram and as you raise the fsb. I guess the ram speed increases in sync with that so you could infact raise it up untill your ram is back to normal speed providing you've not fired your cpu by then is that right?

Ive read murys guide 5 times over now i think I'm begining to get the idea lol. Would be great to speak to some one with exactly the same compnents as i have to see what their adive is but I guess thats unlikely lol Thanks for you help so far I'm gonna reserch it more. :)
 
Yeah , ur starting to catch the draft. For example ... looking at ur future configuration ... to use fully in a 1:1 ratio (best performance) u'r 800mhz ram u'll have to set a 400FSB ... that will translate for u'r CPU in a 400X9 freq => 3600ghz. It's unlikely that u'r sistem will pe fully stable at that speed .. even with that Zalman. Anyway the best deal in ur case ... is to lower the multiplier to 8X and maintain the 400FSB => 3200ghz ...and still u'll have to do some Voltage tweakings to get the sistem stable .. but its something achievable . Just put the parts togheter and start tunning .... patiente and tobbaco ! 😀
 
I would certainly be happy with 3200mhz. Well yes I think the best thing is to get it all built up and do like you say. Ive not even seen the bios in person yet so probably best to see how scary that is first and read up a bit more and ask you guys later when I can see what the deal is.

Thanks again for you help guys no doubt you'll hear from me again lol

:)
 
Well ... in any case this is NOT a rule ! Every processor is different and acts different given the same circumstances ... even if its the same model! Also there are other variables which could affect OC performances from one sistem to another ( MB , RAM , PSU .. and so on) . Bottom line , u can't be sure that 2 E6300 will perform similar on the same sistem ... guessing what an E6600 will do related to an E6300 performance ... its just fairy tale
 
Overclocking your current setup isn't bad at all. I got pretty much the same system and current running at 3.4 Ghz at 34C.

Core 2 Duo E6600
Asus P5WDH Deluxe
2GB XMS2 6400C4
Zalman CNPS9700
150Gb Raptor
4 320 Seagate Barracuda Raid5

The BIOS setting are pretty simple, and took about 2 mins.
Some of the current settings
Mem Voltage 2.15V
Core Voltage 1.50V

Good Luck!
 
I have a similar set-up:

P5W DH
E6600
Stock HSF

2GB XMS2 PC6400 DDR2-800 4-4-4-12 (different brand RAM, otherwise similar).

For starters, even if you don't want to OC, you'll be wanting to go into BIOS anyway, since at default settings that mobo will not be supplying enough voltage to the RAM; It will be giving it 1.7, or 1.8 or something (on the Auto setting) - and this basically means the RAM only gets recognized as PC5300 (running at 667 MHz as oppposed to the 800 you paid for). The timing on mine (and many others judging from the ASUS forums) was also set to 4-5-4-15. So if nothing else, get in there and set the voltage to 2.1 V (http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_6400_ati_crossfire_dual_channel), manually change the frequency to DDR2-800, and Disable SPD so that you can manually set your timings to 4-4-4-12.

If you follow Wusy's guide, you'll be wanting to disregard SOME of the what I just said (everything apart from the voltage change actually); As you already noted, you'll be actually REDUCING your RAM frequency initially. Then bumping it up again (automatically) as you bring up your FSB to OC.

Using Wusy's guide (awesome), I found I could just about OC to 3GHz with the stock Intel HSF (58C, Orthos / Core Temp). With your Zalman, you should find you can do this comfortably too, although as Tribal pointed out, every set-up is different (I do have a reasonably well ventilated P180 case, and you have to take the CPU lottery into account). Hope this helps.

EDIT: Reread my post, and in that last para I make it sound like 'your Zalman should just about perform as well as my stock HSF' :lol: . What I meant was, if I can do 3GHz w/ stock, you will clearly be able to out-perform that with the Zalman.
 
Yeah I have clocked it up to 3.0ghz exaclty now and the ram is slightly overclocked at 2.15 volts - 835Mhz - 4-4-4-12. It seems to be running real stable.

I have a Thermaltake Xaser III alloy case. It's well ventalated with 4 Intake fans x2 front blowing across my western digital hard drives ( both luke warm to the touch). x2 at the side which are blowing cold air right onto the front end of the zalman. There are x2 extraction fans on the back and x1 on the top of the case. My ocz PSU sucks out alot too.

As the zalman is so massive ive only got about half an inch clearance between the intake fans so is real breezy in there. My thermal take case came with a temp readout display but the thermomiter wont fit underneath the cpu like it did on my old athlon so now I have it between the 2 ram chips furthest away from any ventalation.

Idle my CPU is 26-27c, MB is 36-37c & Ram (on surface of heatsink) 45c

On load CPU is 29-30c MB is 37c & Ram 45.5c

SO all is cool and stable though I worry slightly about the ram I wonder if it will be ok at the settings I have for it now

Excellent!

I wouldn't worry TOO much about the RAM @ 2.15V (I know that at this setting the number is in RED in BIOS, which made me worry at first too). Your RAM is rated @ 2.1V, and has EVP (Extended Voltage Protection) up to 2.2V, according to the manufacturer:

Make sure you are using CoreTemp the free proggie for your core temps, not sandra or some crap. I have a CM stacker 830 which is very well ventilated with my e6600 at 3333 MhZ (1.4125 Vcore) and a Scythe Infinitiy with the core temps at 46C & 42C at idle and around 48C-50C under load load. Other programs read far below that because they use the mobo temp near the CPU.

Hi I'm using Core Temp now and I got 2 normal readings and one worrying one!

Idle they read

Tjunction 85c!!!!
Core #1 37c
Core #2 39c

So how hot can these chips handle safely I'm at 3ghz at the moment

Don't worry about the Tjunction reading, its the Cores that you are interested in. 37 / 39 at idle is completely fine.

In general, you want to keep those at or below 60C when under load from something like Orthos. If the temperature reaches 80 - 85C, the CPU will actually automatically start to throttle itself back, to prevent damage.

You certainly aren't going to damage your PC if, during the course of your OC'ing adventures you go up into the 60's while testing, not at all. But when it comes to selecting their final OC settings which they will run day-to-day, I think most people feel happiest when they are at or below 60C.

What program are you using to stress/load your CPU?
