Its a good start anyway. I found that high fsbs like that need some extra voltage to the NB to work stably in most cases.
Just a case of tweaking it till its right.
I notice you have the P5B-E, does it only have 2.1v vdimm? and doesnt your ram need more than 2.1v? :)
No worries, mate. :bowdown:
Yea, and I've tried to OC through the Bios but same result, need to clear cmos once over 315fsb. :confused:
Now I'm running at 312 x 9, set through Bios. DDR2V at 1.90, and 1.60 for MCH1.5V.
Could it be the memory timing? It's now running at 4-4-4-12-16 according to CPU-Z.
Funny enough, the voltages for vdimm and vcore can go up to silly levels, but yeah, I have my RAM set to 2.15v atm due to the underclock. The BIOS also has really really neat voltage markers, so when you go over safe volts it marks them purple, when you go into red, well, use your imagination. ;)
Yeah, maybe if I get a watercooling loop :P
I'm gonna sit at 3.2Ghz at least 'til I pay this thing off lol.
Is there an easy way to tell if it's the CPU or RAM or mobo that's struggling with an overclock ?
Sure, if it doesn't start. That's the first give away. TAT can tell you if you've pushed the CPU too far, Orthos ensures electrical/ram stability.
Added some Abit Quad GT bios shots, so hopefully that will help a few people. Thanks to Daza for the screenshots. :)
This is why I recommend to keep the ram at 1:1 and use a minimum of pc2-6400 for overclocking. That way, you have a theoretical overclock of 3.6ghz on the cpu (e6600) before you even start to overclock the ram. Ram doesnt overclock like CPUs, so its always best to have some headroom in the ram department. Another cause of overclocking failure is that the Northbridge is too stressed, you can either feed it a touch more voltage, or get better cooling, or both :)
What is a good NB cooler for the P5B Deluxe? I was lookin at gettin the Thermalright HR-05 but according to the TR site it isnt compatible with P5B Deluxe. Any other that are good, without Wc ofcourse, that comes later:)
Well Orthos has been running for 3 hours so far with no problems, the CPU is holding at 45/46C over both cores, and 53C at the Tjunction, with the NB at 34C, all on air, I'm fairly sure a new 500W PSU, reseating the NB with AS5 and adding some ramsinks to the VRMs will help a great deal since those loaded temps aren't really too high. I'm more than happy with the results so far, and FEAR timedemo ran at a minimum of 44 FPS.
Chuck a 60mm fan on this and heat isnt an issue.
I would be surprised if a new PSU improved your overclock, unless the current one is a bit flaky of course.
The best thing you can do for your board is dump the heatpipes and get a half decent aftermarket NB cooler. Chances are that the heatpipe thing doesnt sit flat on the NB anyway :)
Actually there's no dodgy heatpipes on this board, though the mosfets are bare as you can see from here:
http://uk.asus.com/999/images/products/1399/1399_l.jpg
It's a fairly nice, well laid out motherboard, plus it wasn't silly priced like most of the heatpipe models. You can see the specifications here, and my current FSB clock speaks for itself.
The PSU is decent but it's also 4 years old and it's had a P4E sucking the life out of it since I bought it lol. Plus it's not as efficent as modern designs, and the excess cabling isn't very attractive inside the Antec 900 :)
Ah, I see what you mean. I wonder why they chose to put those hooks for the NB cooler on the E version :)
No idea, but I have tons of cable ties that might do the job if I decide on another cooling method, but it's fairly easy to reseat, done it before on the P4C800-E board that I got for the Prescott. But it does sit evenly on the NB, and stays very cool even with the crappy thermal pads that are used.
The Scythe Infinity cooler sits from about 1/3rds across the NB, near the upper edge of the board, covering the "Asus P5B-E Plus" markings and right over the mosfets on the back of the board. I have the vantec steath almost sitting on the first RAM module. It seems to work well, the top of the Scythe is cool to the touch anyway.
What about the hr-05 SLI? that bends out of the way, and apart from the shape of the pipes, I think its pretty much the same.
Yeah I looked at that too, but on the TR website it doesnt even mention the P5B. I might just get a HR-05 and the SLI to be safe.. Unless some1 has a AC7 Pro and uses one of these HR-05 coolers? Will be gettin the TR 120 Extreme when it becomes available and thats gonna be another story as its huuuge
Im wondering if it means its not compatible because you need to fit a mosfet cooler as well? Thats all I can think of.
Wait til you get watercooling in there, now thats some weight.
Great guide clunk managed to get my 6300 upto 3ghz stable now at 43 degrees idle. Wouldn't of been able to do it without this guide as this was my first overclock. Thanks again :bowdown:
No worries, please feel free to send large wheelbarrows full of cash and precious jewels to me, you know it makes sense :D
Would increasing the northbridge voltage increase the stability when overclocking?
If your jacking up the fsb yep, but see how far you get on the stock voltage first on the northbridge till you start increasing it.
Oh and make sure you've got some cooling on it.
How do you monitor the northbridge temp?
I use everest and can't find the northbridge temp, I find an "Aux" temp but I don't know what that is.
Uguru?
nope uguru doesn't work

Reckon I'm on the right track with a lowly e6400?
Temps currently at ~53C
Hopefully Orthos will run fine over night.
Looks good to me :)
How come the ram is at 5-5-5-17?
5-5-5-18 on geil ultra? If its working ok you can always try it at 4-4-4-12 :) To be honest, the timings dont make a huge difference to speed.
http://img473.imageshack.us/img473/8209/orthos2qh1.png
After 17 Hours. Current load temp is 50 both cores. Reckon that's stable enough?
Looks good enough to me :)
You going for higher next?
why cant you reach 3ghz?
Just restart the pc to get rid of it.
I tried 3000 and it wouldn't post
EDIT: Oh right you mean I left Orthos on? I wasn't using the PC so I just left orthos on, just wondering if it starts the tests again once it finished all it's cycles.
No, it carries until you stop it or turn off the pc.
Hmm, have you got the mem voltage set right?
You may also be at an fsb hole, which is just a small part of the fsb range where its not stable, so you could always try higher, to avoid the hole, try 400fsb with the vcore set to auto and the ram voltage set to whatever it is supposed to be, and give the Northbridge a bit more voltage, but keep an eye on the temps and see how you go, or if you dont feel adventurous, try it at 380fsb or 390fsb.
got the voltage at 2.1V for the mem.
Got it to 2998MHz
http://img502.imageshack.us/img502/9127/cpuz2998fo8.png
Just started Orthos now.
oh and cant find anything at FSB 350Mhz or higher that is stable (so far)
Got past the first 30mins on Orthos. Normally fails straight away, so it's looking good so far.

It's made it over 15hours. I don't think I'll get it above 3GHz.
Thanks for all your help Clunk
I cant see why you cant get over 3ghz, you arent near the rams limit, cpu should have some overhead left. Did you try giving the northbridge som extra voltage?
It doesn't want to POST at 3GHz or above. With this mobo I have to enter the Rated FSB (or QDR) which works out to be half the clock speed on the e6400. 1499MHz seems (at the moment) to be the highest QDR that the system will post with.
I'll have a little play with the voltages. I think I've already increased the NB to 1.31 from 1.2, how high (conservatively) is safe?
Ah, sorry, I forgot you were on a 680.
Well, Ive not used that one, but theres a few things you can try.
turn off the sli memory thing.
turn off linkboost.
turn off nvidia gpu ex.
turn off all the spread spectrum stuff.
turn off ALL the cpu options, speed step, vanderpool etc.
disable sli broadcast apperture.
try setting pci-e frequency to 110.
make sure your ram is set to 2t for now.
change to unlinked and manually set the ram to 800mhz, and the cpu to 1600qdr (or whatever you like).
NB voltage to 1.40v
SB voltage to 1.50v
HT voltage to 1.2v
Failing that, try the abit forums, they will probably be able to help you out better than I can :)
i had to join this forum, just because of this guide! :mrgreen:
it is exactly what i was hoping to find! :bowdown: thank you for making such a simple explenation with good pictures.. ive gotten alot of the questions ive had around overclocking answered!
ive been looking for a good guide, because next week i am finally gonna buy myself a real badass stationary computer! ive always had laptops and such due to school/work etc., and i am very keen on doing an overclock attempt.
im getting the e6600 and the pb5 deluxe so it will be easy for me to follow your guide.. could you recommend me a good psu for my system? and are GeIL DDR2 PC6400 Ultra 2 GB good ram chips for overclocking like this?
if you have the time, you could check out my setup so far,
and see if you would recommend me to change anything.. i want the best premisses to get a good clock..
prisguide.hardware.no/vis_handlevogn.php?waggon_id=46392
I dont know if you have the time or are interested in helping me out with this, but if you can, it would be higly appreciated! :D
The Ram is good, it will allow u some headroom to overclock. The Cosair 520/620W are good Psu's, just got a 620W yesterday and it looks good and has plenty power. If you use ebuyer you can get £10 off each purchase so try that, unless u can get it cheaper anywhere else. P5B Deluxe is great for overclocking so u shud have no problems there. Any other stuff Im sure Clunk will advise:)
Edit: cant find ur spec on that page, [prolly cos Im dumb. Might be helpful to fill the Spec thingy on this site so its easy to access.
Heres the link.
Looks like a good choice of stuff, have a google and double check if the xfi plays nicely with the p5b, I have a feeling it doesnt, but I may be wrong :)
Dont forget to vote for the thread if you find it useful :D
Edit: Yes, Corsair 620w should be fine.
Hmm I got Creative Sound Blaster X-fi Xtreme Gamer - Fatal1ty Professional Series, will have to check on that b4 I put it in the Deluxe. Btw Clunk, got Mb, Psu, case,TR 120 Extreme(ordered last night) ordering Cpu and Ram today so shud have an Overclocker by this weekend *fingers crossed*
thanks! i tried to google it, but didnt find anything relevant, i probably used the wrong keywords.. but i just chose the soundcard on random, so if you could recommend me one that you know works well, it would be great :rolleyes: i only need the soundcard for regular gaming and music use..
thats a pretty good point, is the onboard audio on the pb5 deluxe good? if so, im gonna go with that! this computer is expensive enough as it is.. ;P
It's got HD Audio, there's no driver problems with it what so ever on my board, and I wouldn't imagine it would on the p5b.
To be honest I'm not an audiophile and I've only bought soundcards for previous rigs because they wouldn't do 5.1 and microphone input with only having 3 sockets.
For me, at least, a soundcard seems a waste of time as the onboard does everything I need.
About time :D Where did you find the Thermalright in stock?
The auzentech cards are great, especially if you want to connect directly to an av amp.
Ive never used the onboard sound on the p5b, but I remember reading that some people had experienced clicks and pops, but that could have been due to other things.
Agreed, and a cheap soundcard is generally better than the onboard sound :)
Ah I see :)
is the noctua UH12F a good cooler? i chose it so i can attach 120 mm fans on it, like i am going to have in the rest of my board.. anyone have any experience with this cooler?
I beleive so, although havent used it myself. Also have a look at the big scythes and the thermalright 120 extreme.
Not too bothered about this but just out of interest. I can't get above 3.1ghz without random restarts. All the way up to 3.0 is fine, never does it, but above its not stable at all. The temperatures are fine.
This is on a 6300 and a 550w psu. Maybe thats as far as this setup will go?
Have you definately got the ram voltage set correctly? Entered the Timings properly? Added a bit of voltage to the northbridge?
Are the temps ok? What 550w psu is it?
The psu is a antec 550w truepower.
The temps are fine idle at bout 42.
The ram voltage is set to 2.1, The timings set to 4-4-4-12 on geil ultra.
Not changed the northbridge yet.
What about the northbridge temps? Sometimes the heatpipe isnt actually making contact with the NB and it all just gets really hot.
So where do you check the nb temps in bios i take it ?
Asus probe is a good start.
You never guess what comes up when you type in "c2d overclocking" into Google :)
Very good guide Clunk :)
Yes, its number 1 :D
Number 2 when you search for c2d overclocking guide.
I wonder how to fix that?
When running Orthos do you want to set the affinity and run 2 versions, one per core?
You dont need to set affinity in orthos, just one version is enough for a dual core :)
Ahh, I've been running 2 versions, one per core...
Temps here are 54/52, maybe cos one cores working harder, maybe the HSF aint seated properly, maybe the cap thing aint flat..
No need, itll probably send your pagefile daft, unless you manually set the amount of ram to use.
54/52 is fine, completely normal.
lol stopped one and now its 51.43..
Will change the affinity the otherway in a mo and get it warm the other one...
i am wondering about theese new c2d's thats coming this summer.. they have a FSB on 1333, but how does that really help? because it is the FSB that determines the speed of the cpu, right? so.. well.. im not really sure what im asking for, im just a bit confused :p should i wait and get a board that can reach 1333? isnt that just like overclocking..?
a hah, i think i get it.. with the higher fsb, the new proceccors, with the same mulitplier, gets a higher core speed.. but, if you put a new c2d on a mobo with a lower fsb, then you would not get the speed you should get..? i am looking at the p5b now, and i cant see any rated fsb speeds.. am i all lost here?
i was going through the guide again, and read over.. so, with theese new FSB speeds, the e6600 would be a 3ghz instead of a 2,4? 9 x 333mhz fsb.. i think im getting it now.. but what i dont understand is, why are there coming new c2d proceccors, isnt it just the mobo that gets the extra upgrade?
(sorry about all the posts :embarrassed: )
As far as the FSB is concerned, all that will be different is that instead of the default being 266.6mhz, it will be 333.3mhz. 333.3 mhz quad pumped = 1333fsb.
Currently, its not too hard to make existing c2d chips hit 1333fsb, simply by raising the fsb to 333, most decent motherboards will let you do this.
Have a google of intel penryn, that should explain further about the new cores :)
Speaking of which, the thing I find odd is that Intel use the same volume of L1 data cache as L1 code cache, since Intel started the movement towards SIMD instruction sets I would have expected they would have at least twice the L1 data cache so the data buffering can keep up with the flow of instructions with less data cache misses.
i read at about the penryn family here on hexus, and i fairly got the points i think.. but arent there coming new c2d this summer aswell, with the 1333 fsb? typically named e6650, e7650?
Yes, I'm not 100% sure on the correct details, but if they are based on the conroe core, they will be the same, but with 333 (1333fsb) instead of 266(1066fsb).
Mines been sat at 1333 for just over 24hrs now running Orthos while I've been out, seems fine...
Mines been sat at 1800fsb for the past week nah nah, Right anyway my question do these temps look ok to you lot or is there a bad bond somewhere: E6400 at 450x8 @ 1.46 Idles around 45c and loads at 55c ish happy for it to go to 65c if it needs as Im after a E6240 if this one pops it clogs. :mrgreen:
(Yes it watercooled)
Those temps look fine to me, now if I could just sort my own out :lol:
