Overclocking my new Rig. (P5B-D w/E6600) Lots of Info!

Let me first off say I've created an .xls file for people to use. It's of all the BIOS settings for the Asus P5B-Deluxe motherboard. Use it, spread it around, do whatever you wish with it.

P5B-D Bios Screens Excel Spreadsheet

By default it contains my settings as of right now.

Here is a list of my parts:

Intel Core™2 Duo Processor E6600 2.4GHz w/ 4MB Cache (L628A264)
Thermaltake Big Typhoon VX 120mm Silent Heatpipe Cooler
Arctic Silver 5 Thermal Compound
Asus P5B Deluxe - DualDDR2 800 Motherboard
Kingston HyperX 2GB PC2-6400 Dual Channel DDR2 Kit (2 x 1GB)
Sapphire Radeon X1900 XT 512MB GDDR3 PCI-E w/ VIVO, Dual DVI
Arctic Cooling Accelero X2 VGA Cooler
3x Seagate 320GB Barracuda 7200.10 SATA II w/ NCQ, 16MB Cache
Mitsumi 7-in-1 Internal Card Reader + Floppy Drive, Black
Plextor PX-755SA 16x16 Dual Layer DVD+/-RW, Serial ATA (Retail)
Thermaltake Matrix Va Mid Tower
Enermax Liberty Modular Power Supply, 500W
Win XP Pro SP2

I've basically installed winxp and loaded drivers. Now I'm trying to ramp up the speed to it's highest stable limit with acceptable temps.

Using Programs:
Coretemp
3dMark06
Orthos
SuperPI

After reading through a ton of threads on the 'net I've been able to get my system to run stable at 3.25GHz (356 FSB x9) and keep my load temp at under 60*C (Core temp, Ambient 23*C(warm))

By stable I mean Orthos, SuperPI, & 3dmark 06 Stable.

My main question is what do I have to do to get this thing running faster but not hotter. Below are my BIOS settings... perhaps I missed something? or maybe I have to re-install my HSF? (I'm thinking I could get my arctic silver on better?) Oh, and if I lower my core voltage from 1.4v I get unstable in Orthos. (atm)

And finally...a picture:

first of, your temps are not too bad....normal for air cooling. with that OC, you can run your Vcore lower, to say 1.375 and still be fine, while dropping your CPU temp a couple of degrees.

but you got a lot of work ahead...I suggest:

1. Start with RAM timings....play with that and see what is the tightest yet most stable you can get. You should be able to hit 4-4-4-8 fairly easy if you do it right, but at least 4-4-4-12-4-35

2. Once you get that squared, get your FSB, NB, SB voltages out of Auto if you plan on bumping your FSB some.....best to have manual control of that.

3. Start to increase your FSB by 10 increments, to say 370, then 380, etc.....keep in mind though that the P5b-deluxe has some known issues between 350-400fsb, so you may wanna skip this whole range and jump straight into 401 fsb.

keep iterating, and watch your temps.....also, make sure you have a good seat on your Heatsink.

good luck, and congrats

Not sure but I had a real tough time getting my E6600/P5B D/Corsair 5400C4 over 325 with any stability. Then I just said F it and bumped up all the voltages to near max and set the FSB to 401. No it didn't boot inkto windows, BSOD, but then I reset it to stock, loaded the 614 BIOS, again reset to default BIOS values and then I was able to get it to 356. This was with CPU V @ 1.425, Mem @ 2.15 and NB at 1.25. I have since been upping the voltages across all parts and now have it running at 378. But that is about it. I tried 401 again last night with voltages higher and got to the windows welcome screen for about .01 seconds then BSOD. For me to run at 378/3.42GHz I need 1.4375 CPU V, 2.25V Mem, NB 1.45V, FSB T V 1.5? (Not sure I'm not at home). I also have Vanderpool disabled.

I suggest what ssabripo is saying but doing the memory last, loosen out the memory to something like 5-5-5-15 on 1/1 (fsb 350 mem 700, fsb 400 mem 800 etc) to get memory out of the equation and once you have your CPU settings to your liking then start messing and tightening the memory to something like 4-4-4-12 or even better if you can at 1/1 or even 4/5 if you it will let you, also 401 and higher seems to be much easier than working on the 360 to 400 range even do this might be quicker that 401, 425 or whatever you can get until you reach 467 and higher I think.

This is a highly recommend read (probably why it's part of a sticky ;) ) and will explain it much better than I can

Just my 2 cents and let us know how it goes, as I'm working on a similar setup


Good luck

M@iden

nice pile of toys.

You should aim for 8 x 450ish at about 1.45v.
(change multi)
Run 1:1 as tight as the sticks will go. Hopefully 4-4-3?

Thanks for the advice guys, I'm going to try and take it further tonight... we'll see what happens.

One thing I'm confused on is Core voltage.. I'm at 1.4v and running 3.25GHz, will I need to up this voltage for a higher clock speed if I reduce the multiplier and aim for a high FSB? If so, I'm not sure it's going to be possible due to the heat that more than 1.4v will cause?

what batch/ week is that?

mine easily hits 400 * 9 @ 1.45v without breaking a sweat and everything else in auto

my mems hit 890 1:1 4-4-4-12 @ 1. 8vdimm ;)

L628A264

I can run SuperPi and other programs at 400x9, but Orthos isn't stable.

I just found out it might be my memory holding me back... it seems to like 2.2 to 2.3 volts... I was undervolting it before

EDIT: Above 400FSB this allowed me to get a little further in orthos, but not totally stable (see below)

I disabled Vanderpool... that seemed to get a bit more stability from orthos...

So far the best orthos stable settings I have got are..

3.2Ghz, (8x400FSB) This settings has allowed me to stay in the 1033 strap and gain alittle extra from my memory. I am able to do this at 1.4 core volts @ 60*C load.

I'm having a hard time getting anything above this setting stable.

SuperPi: (1M) = 15.766s

turn your NB vcore up to 1.45 at least, recommend 1.65 for highest FSB.

Turn up your multiplier to 9x. Put cpu volts at 1.5v...

If i were you i would try for 9x400 with the changes i made. However dont be surprised if it doesnt boot it, luckily asus makes overclock recovery easy.

Dont watch temps for now, see if its stable first. ;)

Good luck!


Edit - BTW Welcome to XS!!!!! :toast:

hmm.. thanks for the advice, but I'm pretty sure I won't maintain under 60*C at 1.5v

Is there any way around that without watercooling?

Lap your processor and the bottom of your heatsink if you haven't already.

Is there a guide somewhere on how-to lap a c2d?

My bios settings: hope this helps!

IM 100% orthos stalbe with those settings. if i want to up the fsb to 445 fsb * 9 i just increase the vcore to 1.5 and leave everything else to AUTO

Often it helps setting PCI-e freq. to ~96MHz instead of raising it.

Well I think I've found my sweet spot.

It seems to be 361FSBx9= 3250mhz. I can run this stable @ 1.4vcore even with C1E and EIST enabled. This throttles the cpu to 361FSBx6= 2166mhz during low load/idle. I'm pretty sure this will be my best settings for everyday use. Stable meaning, Orthos, SuperPI & 3dmark06.

Temps with reported by Core temp are below 60*C @ load with Orthos. (42*C Idle)

Total system power = 204w (Idle) 259w (orthos load) 310w (3dmark06 load) Includes LCD Monitor.

I tried playing with everything and it was really hard to make anything stable without increasing my vcore which brings up the heat.

I might try again if future bios updates makes the 378FSB more stable.

I've got an L628A264 as well, purchased in Toronto Canada, where'd you get your's?

I bought mine @

www.memoryexpress.com

in Edmonton, Alberta

After deciding on the final FSB & CPU ratios I decided to try and dial in my RAM timings... something strange happened.

I lowered from CAS 5 to CAS 4 and my SuperPI times Increased! So I'm thinking I'll leave them where they are at. 903mhz @ CAS 5. (361FSBx9) 4:5 RAM

My idle temps are 52*C and load is 74*C. This is MUCH better than the stock HSF, and at a fan speed of 1/3. (it's super quiet, infact I can't hear it)

(Zalman is no better and costs much more)

Others say similar...

Psyire;

he's trying to tell you to get a cooler for the cpu!!! not talking gpu cooler....

If that is the case, I have no idea why he would say my MB will get cooked? or mention the Accelero? ohwell, no big deal...

I was out of town for a few days and now after getting back and reading up on my SATA Burner problem... it looks as though I may need to reinstall windows again. (Asus and JMicron really need to do lunch and fix their problems)
