How do you do it?

[jimmsch]

I am a complrtr NooB to OCing. I am running Core 2 Duo E6600 on an ASUS P5W Deluxe mobo with 4GB Corsair DDR2 800 RAM and 2X 250 GB HDDs in RAID 0 config. I have the latest 1506 BIOS. I can not get this thing to overclock at all. I set the CPU freq to 300 and the RAM to ddr2600 all else at auto .
In POST it reads core 2 duo at 2.7ghz (yippee) RAM at 4800...but won't boot past the windows splash. Can somebody help me?

Running at stock 266mhz with 99X multiply and RAM set at DDR2 800 1.9v works great.

:welcome: to OCF :D

ISO images suitable for creating a bootable Memtest86 CDROM
Download - Memtest86 v3.2 ISO image (zip) <- click on that link and download it, burn and ISO like you would a operating system.

Now.. put in that CD and get ready to boot to CD.

enter the bios

Disable unessary services in bios an up your Vdimm a little, 2.0 would be a good place to start but 2.2Vdimm should be a safe max without active cooling.

Set your ram divider to 1:1

Run Test 5 in memtest for the FSB that you would like to run on the ram.

once you can pass Memset Test 5 you can boot up in windows from the HD :thup:

Good luck :D

Give the vdimm 2.0v and bump up vcore one notch. Then try 300 FSB with the memory set to auto and SPD timings.

does anyone else think its odd that he has a 99X multiplier? hope you ment 9x

Thanks for the helps. I managed to get it to boot at 2.9ghz using stock volts, but it was not stable. I had it stable atr 2.86ghz using stock volts, but figured this was maxing it out. So I fiddled around a bit and decided I like running it at 2.7ghx, stock cpu volts (auto on my mobo) and bumping the RAM from 1.90v to 1.95v. This gets the system running smooth and according to AI Booster the cpu temp is 21-22C idle and 27-28C at normal load...37C at MAX 100% cpu usage when running orthos.

This is with the system in "silent mode" as optioned in ASUS BIOS.

However my hardware system monitor reads 33C for the case and 28C for the cpu at idle, and never changes even under load.

I have a Zalman 9500 heatsink w/fan and 1-80mm side intake fan...1-120mm front intake fan...1-120mm top blowhole fan..and 1-120mm rear exhaust fan as well as the lower passive openings in the side of the case under the vid card.

Does anybody know of an accurate sys temperature gauge/monitor?

Thanks again for the help

coretemp or intel's TAT will pretty acurately give you the core temperatures.

SpeedFan for system/HDD

CoreTemp for CPUs

Keep on the good work, you can go past 3.2 with that!

yup 3.2 was about as far as I got . It seemed stable but I do not really want to run it that hot for everyday use. It was 47-48C at idle and got up to 51 - 52C under orthos load.

Anyway I decided I like running it at 300FSB (2.7gig @ x9 multi).Temps are in high 30'sC idle and get up to around 48C under orthos load. I always run 2 instances of orthos..one for each core.

I was just wondering if I will get better performance if I lower the multi so I can get the 1:1 on my DDR2800 Corsair RAM. This will give me a FSB os 337. I am going to try it and see what happens.

Also I plan on posting some pics of the mod I did on my old PC, can somebody point me to some directions on how to post pics on this site. The topic on mods asks that we post the actual pics here...not just links to the pics.

EDIT: I fiddled around a bit more lowering the multi and keeping the speed @2.7. It booted OK at @ 338 with 8x multi. But again the temps were a bit too high for my chicken**** arse near 50C. I also tried it at 386 with 7x multi...no POST

I thiunk the best for me and 24/7 usage is going to be 300 with 9x multi...running my 4GB of DDR2800 at DDR2600 with the timings tightened to 4-4-4-10-4. This see,ms to be cool enough even for me and faster than I ever thought a PC could be. Although I must admit I did like the way it ran at 3.2ghz...but I am afraid to burn it out too fast. Maybe if I win Lotto

Thanks
