e600 p5w dh overclock

[imported_browsing]

I'm having a heck of a time trying to get this stable. Here are my specs:

e6600 (week 28)
Zalman CNPS9500 LED
p5w dh deluxe
2x1 gb OCZ 6400 platinum rev 2
x1900 xtx
pc&c silencer 610
150gb raptor
4 x 320gb Seagate .10
Antec p180

My mobo temps are between 45-51 depending on how high I have my fans, I've done the n/s bridge mods to remove the foil and replace w/ as5.

My cpu idles around 39-41 at stock and I can't OC it above 3.3ghz (1:1 memory at like 711mhz) before it starts popping over 60C on orthos stress.

I'm new to overclocking but my ram conks out at anything but 1:1 at non-stock settings, at least I believe. Can anyone give me a walkthrough for my setup/mobo or at least explain the different combos that have worked for them? As you can see, I spent a decent bit of cash on this thing and just feel bad that I'm apparently stupid and can't get it figured out. Especially dissapointing is the memory performance, I thought this OCZ was supposed to easily get to 1000mhz, but I can't put it above 800 before I start having problems.

get your mobo at 400 FSB (1.6 MCH + 1.4 FSB + 1.2 ICH)

set RAM 1:1 (stock speed stock volts)

set CPU to 8x for 3.2 ghz (1.4 vcore)



Now find out how much volts you need to stay at 3.6 ghz stable. From my experience you will need 1.55-1.65. If you need less than 1.55, you have a good chip. If you need more than 1.55 I would give up the 3.6 ghz mark and stick with 3.2 (anything over 1.55 is too much for air cooling)


Theres your crash guide to E6600 overclocking.

The main thing I'm worried about is the core temps getting over 60, but I'll definitely try those settings out and report back.

Get a TT Big Typhoon.

How much of a difference in performance is that compared to the 9500?

All I can tell you in my experience with C2D and P5WDH and that ram is this setup runs very hot. And when you add voltages and start ocing, it gets hotter.

If you cannot control the heat output of cpu/mobo/ram, then you are very limited to how high you can OC regardless of what fan/case/cooler you use.

My suggestion would be to use manual memory timings and set them up to 5-5-5-15 and use only 2.0vdimm to start and see how high your cpu/fsb/memory at 1:1 ratio can go.

I haven't OC'd the memory as far as voltage goes. The default voltage for it is supposedly 2.1.

Not sure if this is related, but I had memory compatibility problems with the exact same OCZ modules that you have on my P5B. I was even running stock timings and speed and was still having memory test and Prime95 errors.

How do you set CPU to 8X in the bios? I thought non-Extreme CPU's were locked, in this case at 9X.

Starting with BIOS 1401, conroe multipliers are unlocked downward only.

You can grab 1403 here:

Thanks Phil. I knew that ASUS had done that with the P5B, but I didn't realize that a P5W bios update existed yet to allow that for the 975X chipset.

My week 24 E6600/P5WDH will not even post with those settings. I even bumped the vcore to 1.45, vdimm from 2.1 to 2.2, and enabled SPD. Nada. Rig refuses to post with the FSB at 400.

Any more suggestions?

Phil,

I had a week 24 e6600 (and p5w deluxe with zalman 9500) and I was only able to get to 3.2ghz with it. I tried EVERYTHING, but unless I was goign to give it >1.50vcore, it refused to go above 3.2. So I sold it, which is harder to do now, and got a week 28. With this processor, I can get to 3.4ghz with 1.4750v, about the same volts as my week 24 did at 3.2ghz. I know week 24's seem to not overclock as well as the week 28 and week 27 is even better yet (some are hitting 3.6 with that voltage).

My temps are 38 degrees idle and about 54-56 load with the zalman 9500 with 1.4750vcore. I can't get anything above 3.4ghz without goign >1.5vcore which is to be avoided with air cooling as the load temps should not be above 60 degrees. Hope this helps.

Also, on a side note, if you can get 3.2 with 1.4875vcore, that is a good accomplishment. The difference from 3.2 to 3.4 has not seemed to make much difference to me and it not worth the stress.

Yeah, I'm currently stable at 333 w/ 1.35 vcore. That gives me idle core temps of ~45C. I know what you mean about these week 24s needing high vcore. It would appear 400 FSB with this CPU is not possible without boosting vcore to at least 1.5, which gives me ridiculous temps. I can't say I'm at all dissappointed with my E6600 at 333, though. Still a kickass rig.
