RAM timings set to "By SPD" which means CL4-4-4-12 :)
this setup 12 hours dual orthos stable.
Like mentioned, try 1:1 instead of 4:5. Your subtimings may also be too tight. If you're looking for an extremely loose set, 5-6-6-18-6-42-4-11-7-13 or even weaker. I've found vfsb to be fine at 1.2v up to 500fsb even with c2d on p5b. pcie of 103-105 would be nicer maybe, although I usually ran 110 as well.
You shouldn't need more than 1.45v or so
Hello,
I an absolute newbie when it comes to overclocking but i am looking towards a mild overclock of the below components, the system is used 24/7 and the ambient temperature in summer can be schorching hot.
ASUS P5B Deluxe (Latest Bios)
E6600 (Thermalright Ultra 120 Extreme)
4 * 1Gb Crucial Ballistix PC-8500
Other goodies include PC Power & Cooling 750 PSU, some Raptors and XFX graphics card.
I was after a mild overclock to around 3 to 3.2Ghz, while i understand the FSB and mutlipliers i get totally confused as to what speed the memory is running at (ratios?, no need to overclock to memory as i would be happy if it ran at its stated speed), what voltages should i use to achieve these modest gains, any help appreciated.
Great info! thanks
Great hread, I just picked up my Asus P5B-Deluxe yesterday! I think I need to get my water kit out on my QX6700 before I really start overclocking it though :D
i tried to oc following this and my system hanged on me, then computer would not start then had to wait 10 minutes for it to auto default settings. i jsut suck at overclocking.
There should be a noob thread for noobs like me how to OC Cpu's and ram with it.
Okay for some odd reason on my P5B deluxe the Vanderpool Technology is grayed out and I can't change it at all. When I press the down arrow key it skips and jumps to CPU TM function. Does anyone know why?
you have to do a full reset to access this function
Since you already have an E6600 with a higher multiplier, getting a 600Mhz increase in speed is a piece of cake. And you may be able to do it with everything at stock. Right now your FSB is default to 266, just up it to about 350 and you should be able to achieve your goal of mild OCing. To get a little higher than that, up your vcore to 1.4, NB to 1.55 and your FSB to 400 and you will have a 3.6Ghz PC! Easy. Now, this is with an assumption that your E6600 is an average to good OCer.Quote:

I am currently running:

E6600 390 FSB x9 running at 3.52 Ghz
4x1GB G.Skill F2-6400 4:5 running at 975Mhz 4-4-4-12
vMemory 2.35
vCore 1.50 (actually 1.47)
vFSB 1.40
vNB 1.55
vSB 1.60
My temps at load ~ 60C.
Thanks
Great thread... appreciate all the work FCG & others.
I have encountered a problem I have seen mentioned a couple of times in various threads, but never seen a real explanation/solution to... namely, the PC boots up, right through into windows (with the welcome sound and all) but without video signal. If I push the power button, the machine shuts itself down, so I know that everything else is working fine, there's simply no video signal.
Mainly happens when I drop the multi, and head into the 400+fsb range. cpu is stable as, sitting at anything around 380-390x9. It's a while since I done it, but have a quiet week ahead, so hope to be able to spend some time trying to sort it out, and would value any ideas to try.
Value any thoughts. The card is a BBA 1900XT with an Accelero2 on it if that info is needed.
I am completely new to overclocking (my first time) but I have been reading this thread the past couple days which has helped me immensely but I can't seem to get any of the results that are posted in this thread. My computer will start but I will not get a video signal if I try to go anywhere past 325 CPU Frequency. The following are my system specs.
Asus P5B Deluxe
Intel Core 2 Duo E6600
2x1GB Corsair XMS2-6400 CAS4
Thermalright Ultra 120
Seasonic M12 700W
Radeon 1950XTX
I have had this system since November but finally decided to do some OC'ing. I reformatted everything and updated the bios to the most current one but I have not been able to get past 325 CPU Frequency. Any suggestions? Is there are glaring hole in something that I am doing?

Been playing with my OC over the weekend after adding water cooling, and I’ve hit a wall at 9x390. My temps are 30c (Idle) and 44c (Load). My stats and BIOS settings are as follows:
Rig
Asus P5B Deluxe WiFi
e6600 (L704A947 -- not sure how this batch is at OC'ing)
4 GB Patriot eXtreme Performance PC2-6400 RAM
eVGA 8800 GTS
BIOS
FSB = 390
DRAM Frequency: DDR2-780
PCI-e = 105
PCI Clock = 33.33mhz
Spread Spectrum = Disabled
vMem = 2.15v
vCore = 1.5v
FSB Termination = 1.4v
NB = 1.45v
SB = 1.5
ICH = Auto
Memory timings are 5-5-5-15-5-52-3-11-7-13
It was my goal to hit 3.6-3.8ghz on water. Any suggestions as to how to break past my wall?
Also, are these voltage settings safe for long-term use? Any advice is much appreciated.
I would say your Ram is probably the problem. You should be able to use tighter timings at 790Mhz. You might try using only 2GB of Ram. I had 4X1GB and fryed one set at high voltage. When I was only using 2x1GB it was much easier to reach 400FSB. I am stable using air cooling at:Quote:

Try 8x4XX - there's a strap change at 400+ fsb, at 390 your NB is screaming.Quote:

Just for grins try setting your ram by SPD (1:1), NB 1.55v, SB 1.6v and boot at 8x450 - If that's a no go keep the same settings and give it a squirt of vcore, late 6600s like volts. GL!

My first post here, do ignore it if its too noobish :p:
I've had this board since January and have had such a nightmare with vdroop, FSB issues and issues with my pci-E video cards running at 1x... I personally don't think it's too much to ask for a product without so many glitches... ANYHOW back to my issue, I currently can't boot... AGAIN yes AGAIN... usually when I have that issue I just do the switching RAM trick, but it's not working now and I don't know what I'm doing wrong. What's the best way to do the RAM switching trick? I usually put generic RAM in it... it boots fine, then I change the mem voltage to desired (usually 2.15 or 2.25) then save/reboot... wait for it to false start two times in a row and then either flip the switch in the back or hit and hold the power button during the real startup until it shuts down again... and switch out the RAM... I've been doing this for like over a day now and I still can't get it to boot. This happens to me like once a month... I'll come in the room and the PC is not responding so I reboot and can't get it booted up again without switching RAM... Does this happen with ALL RAM that require more than 1.8v or is it just certain brands/kinds of RAM? Currently I have OCZ platinum 8000... anyone know if this RAM has a life time warranty or good customer service so maybe I could ask them to switch out my RAM? Or is there a brand of RAM I should get instead of this? Please help, as I need my pc for my job. Thanks in advanced guys. :confused:
Ive had this mobo for some time now and love reading about how you lot like to push the limits of the P5B.
I finally got around to playing with my settings,here is a picture of how far i got i no its no where close to you all but im new to this.
My clock
:) :D
is there anybody in here using E6750 and OC it by using this mobo? what is your best setting and can you post your setting template? last question, what is new version BIOS for this mobo?
p/s: sorry, new in here and noob in OC world. still learning. please guide me and pleasure to know you all.
Just thought I'd revisit this post I made awhile back. 8 months later I haven't had to change any settings (other than tighten up ram timings and my pc has been rock solid. Although I am getting that pesky double bootup thing where my pc boots, then shutoff then boots up ok. I remember reading threads about this way back when but I forget the fix. Oh well... guess I'll keep on diggin.Quote:
