C2D Overclocking Guide For Beginners P5K Add-On

[Clunk]

Same problem here ibm:



This is with Corsair XMS2 5400, manually set to 4-4-4-12. I've given up trying to monitor my system under Vista 64 bit though, I've not found one app that works as it should Are you running Vista?

Vista is pretty awful when it comes to overclocking, thats why I dumped it. I tried x86 and x64 and they both were a pain in the arse.

Have you tried a bios update though? CPU-Z should work.

[Clunk]

Found the problem. I thought I'd updated the BIOS but hadn't. Now it's running fine on 311

CPU-Z version is whatever is available from the site, 1.4 I guess.

No, I'm running XP (oooooh, with 4Gb RAM too), aiming to upgradge to something 64 in the near future.

Ram is Crucial 2 x 2GB kit (1GBx2), Ballistix 240-pin DIMM, DDR2 PC2-6400.

Just working my way towards 1:1....

At least that is sorted. I'm surprised you havent had more odd problems with xp and 4gb!

[dangel]

I haven't had any problems with XP32 and 4gb... ok, some of it's gone missing but that's all fair enough The board/OS seem to cope just fine tbh.

What kind of problems should I be looking out for? Boils, warts, sight loss? I'm currently running orthos with FSB at 380, DDR 667...will check it when I get home this afternoon.

I figure RAM was uber cheap, if it causes problems I'll take out the additional 2x1Gb set until I'm up on 64bit, and probably won't notice much difference.

How are you running at 380FSB and running the RAM at 667? The dividers only let you run the RAM faster, not slower.

errrr.....I will have to get back to you on that one. There is a small chance that I may have my numbers mixed up.....

Has anybody updated their boards with the new 404 bios? Just saw it now on the asus site.

[Supershanks]

P5KD 0403 bios & 0404

&

P5K Deluxe 0403 / 0404 bios released

Bottom line is 0404 gives better bandwidth but is more difficuklt to maintain stability, i'm back on 0311.

Funny, I thought being subscribed to this thread gives me all updates.

I had the same issue with my board (CPU-Z showing 32-5-5-whatever) and had to bios update to fix it.

What was even more odd was that the bios update apparently failed, yet i'm on the new bios, all the settings are there, its reporting correctly, etc.

It gets even crazier that when I make the settings unstable that the motherboard reports the bios update erro. Set it back to decent but not crazy OC and its happy. Shrug. I would look into it more but its working.

Also running XP with 4gb memory, it only reports as 3.25gb though due to the usual 32bit limitation.

I had to pull the OC from 3.6 to 3 to combat possible heat/voltage issues. One question i've got for you guys. When the cpu gets full load mine jumps from about 35 or so idle up to 60 instantly then over the next min or two reaches close to 70 or so. Does this sound like bad cpu/heatsink contact or a design of the cpu? I’ve got the zalman CU9700 big round CPU cooler. (I forget the exact model number)

My theory is it starts working at full load (using TAT to load it, as it creates the most heat) and thus puts out heat at full load. The heatsink then takes the heat and gets rid of it, but wont actually cool the cpu down so in which case, its not going to get any cooler, its just not going to get hotter, right? Theory comes from the 'do i spend the money on watercooling or not' game… Pondering if I’ll actually see any difference.

What was even more odd was that the bios update apparently failed, yet i'm on the new bios, all the settings are there, its reporting correctly, etc. Very odd, how did it fail? How were you updating etc?

It gets even crazier that when I make the settings unstable that the motherboard reports the bios update erro. Set it back to decent but not crazy OC and its happy. Shrug. I would look into it more but its working. Sounds like you need a full cmos clear.

Also running XP with 4gb memory, it only reports as 3.25gb though due to the usual 32bit limitation. Do you have any of the above problems with just 2gb of RAM in there?

(I forget the exact model number) Depends on the voltage you are feeding the CPU, its high, but for higher voltages, its what you would expect.

Theory comes from the 'do i spend the money on watercooling or not' game… Pondering if I’ll actually see any difference. Again, it will depend on the voltage. Also, check the thermal paste, and reapply, double check that the cooler is seated properly, and possibly use a more powerful fan on the heatsink.

Answers in bold.

well for some reason my board will not oc . I changed the settings just like stated (I have same exact board and cpu) to 333 in fsb and that bootstrap setting, save and exit, pc clicks off, comes back on with the cpu at 2.41ghz. am I missing something?

thanks

Welcome to Hexus

If you can take some bios shots for me, I will point you in the right direction.

[mark319]

thanks for the welcome and I cant seem to figure out what's up with this. so here's some pics of my current settings:









and here's how it boots everytime:



hope you see something that I dont, hope there's nothing wrong with this board. been running it rock solid for a month or so at stock on xp, xp 64bit, and vista 32bit. just decided today to see what it can do now that I know the hardware runs perfect at stock and cant get anything out of it, lol.

[Clunk]

What RAM do you have?..can you post your system specs as well?

[mark319]

p5k deluxe wifi
QX6600 quad core
corsair TWIN2X4096 - 6400C5DHX
geforce 8800
zalman 9700 cpu cooler
rapter 150 gig boot/programs
2x 500gig WD RE2 (RAID 0) on intel matrix
lite-on 20x sata dvdrw

Ive tried many different settings and it will not overclock, lol. I feel like such a noob right now for not being able to figure this out

thanks

[mark319]

well still cant get it to work anyone with any ideas?

could it be the 2 2gig sticks? I've tried with just one stick of ram and it didnt work either?
