C2D Overclocking Guide For Beginners P5K Add-On

[Clunk]

Welcome to Hexus

Ok, firstly the motherboard temps, can you just confirm where you are seeing these temps, and what you are doing when it happens please? A screenshot would be helpful

You will need 5 posts to be able to post links though, so just post what you can.

What PSU is that?

I’ve had absolutely no luck with my P5KC, most of the problems are memory related. Can’t get stability at the 1150mhz rated speed of the Reaper 9200 (5-5-5-18 2.3v) even using the two black slots.

OCZ part number:-OCZ2RPR11502GK
Module size and kit size:-2X2GB
CPU model and rated speed:-E6850 - 3GHZ
Overclocked CPU speed:-3.34GHZ
Divider and FSB used:-9 - 370
Motherboard and revision:-ASUS P5KC 0.2x
Motherboard Bios rev:-0701
Video card:-MSI 8800 GTS
Power supply:-Thermaltake Purepower RX
Operating System:-XP SP2
CPU and System Cooling:-E6850
CPU and System temps:-25-30C

Memory voltage:-2.3V

These seem to be the best settings I can get while stable. Even then though while it can run OCCT OK, Orthos fails after 1hr 30 testing both RAM and CPU. (CPU only is no problem)

What does memtest say? And are you actively cooling the RAM?

What PSU is that?

well its was actually asus probe II that gave me both readings... under full load @ 3ghz using 4 instances of prime95.. i have since d/l everest home and speedfan... but.. i still have AUX temp of over 120c... would this contribute to mb temps??

psu is coolmaster Exteeme power duo 650W

Hi Clunk,

One question. I've overclocked my OCZ reaper 8500 to 1066Mhz. One of those things I find strange is that the asus P5k says its 'native' 1066Mhz for ram, what does this mean? because my ram IS 1066MHz but when i install it, cpu z still reads 800mHz, so i overclock it to 1066 and the 'SPD' tab on CPU-Z says "Max Bandwidth PC2-6400 (400Mhz) , what does this really account for? Shouldn't it read PC2-8500 (533Mhz), ?

Any advice on this would be great because my ram is now at 1066 and asus p5k is supposedly 'native' (not sure what this means) and i was hoping to stretch it to maybe higher.

thanks so much!!

Many thanks for this guide. I'm moving over from a 2.75 gig opty165 and haven't used an intel chip since my 866 p3 so this was an ideal guide .I now have my e6750 running 3.2gig idle temps 20c dual orthos load temps peak @ 40c ambient 20c , on auto vcore,using a freezer 7 and geil pc2-6400 low latency on a plain p5k

how much further do you think this will go on auto vcore?
and what could be estimated as the the full potential of this setup i.e whats the max you think i'll get off this setup?
ps hw do i take a screen shot of orthos cpu-z etc

[silver tongue]

should it worry me that under load my mobo reports 40c on asus probrII

Glad it was of use

The only way to find out is to try it and see

No, thats fine, but if you are worried, just have a search in this thread, or the p5k thread for a pic of the motherboard sensor, and blow a fan over that area.

hey Clunk,

Read your guides both on ram and overclocking, so if i understand correctly, my SPD tab on CPU-Z is basically correct when it reports PC2-6400 (400Mhz). Even though i've set my timings right (5-5-5-15) and voltage at 2.35v. Then overclocked it, by upping the ram frequency, so basically technically its overclocked already done, but SPD will still report it as PC2-6400, is this right? Just to confirm, I'm guessing there's no way to change the Max bandwidth to PC2-8500.

Thanks!

On my new computer now, so I can finally use this guide

Has anybody tried the 0503 beta bios for the P5K Deluxe, are there any performance benefits?

[Supershanks]

have been running it for a few days. Haven't had chance to do any real benches.
Not seen much in here either Asus P5K Deluxe - Intel P35 Bearlake + E6600 B1 / Q6600 B3 release seems pretty underwhelming, generally see a few benches.

[Clunk]

Still on 0304 here

Since P5K premium uses DDR2 does it affect the ram settings or I should be fine with the first post settings?

Also, I haven't overclocked my system yet and I noticed the Mobo temp hits 45-50, should I add the little fans on the heatsinks that I got with my mobo?

My system info is as follows:

CPU: Q6600 G0
Mobo: Asus P5K Premium
Ram: 4GB dual shared OCZ Gold
Vid: X800XL Water cooled (soon to be upgraded to Geforce 8800 Ultra water cooled)

Cooling: Zalman Reserator 1 (water tank removed internal pump) + SWIFTECH MCW50 VGA + Zalman ZM-WB2 CPU Block + Swiftech MCR320 with 3 X 120mm quiet fans + Swiftech MCP655 pump
