P5B Deluxe: BIOS screens for maximum overclocking success

Beefing up the X6800 (cont'd from Page 28)

Final vmods in: 1.45v on nb solid Asus Flash Screen only, won't open to Windows, final left at 1.55v/ 1.25v on Front Side Bus Termination, won't open to Windows (hangs on Windows pre-screen), final left at 1.45v/ Core voltage has been scaled back to 1.45v and doing fine, shows a yield of 1.38v-1.41v in Probe.

So you can't tune vfsb down to 1.2v? That's really strange

[DL Drafting]

Yep. As you suggested, I rolled back each setting separately, so I could see what was happening. The first thing I rolled back was the Front Side Bus Termination Voltage. I had it at 1.45v and took it back to the next lower setting option, which was 1.25v. On reboot, it took me to the light blue Asus splash screen and there it stopped. It would go no further. I waited about 15 seconds, then went through the standard bad overclock recovery drill, went back into bios and reset to where it was at 1.45v and continued with the other settings.

Now, I have another question. What would happen if I bumped the multiplier one more time to 10 x 400? Do you think the core temps would come down further? The FSB would still be 1600, but the northbridge core clock would be even more inline with the stock multiplier ratio mentioned in Tony's discussion. But I don't know if this board and chip can handle 4 gigs.

Beefing up the x6800

For the record, there is a correction. On the last entry, it was the Windows pre-screen, where the little blue dots marquee that the FSB termination voltage lowering caused a freeze-up. I got confused.

Increasing cpu speed will NOT decrease coretemps. What you saw before was most likely due to not manually setting vcore, and as a result, the board assigned a vcore based on fsb, which was why your 9x320 was cooler than 7x400 or whatever your two scenarios were.

As for nbcc, I believe that was to some extent been disproven. It's highly doubted that your cpu will do 4ghz, although you can of course try. Of course, if it were to happen if you had some sort of miracle chip, you should expect no less than 1.5+ load volts to the cpu.

[DL Drafting]

So, like, in other words, do so at my own risk, right?

[ziddey]

I never took any of the risk in you overclocking. But I mean that if you're going for 10x400 with hopes of having lower temperatures than 9x400, then you may need to do a little bit more research is all. That and 10x400 is incredibly difficult unless you have an absolutely lucky chip

Looking under advanced>AI Tuning set to manual will give you something that looks like this partial screenshot:



Anyway, anyone have a reference to the stock values for these voltage settings? I'm running my Q6600 @ 9x333 with a vcore of 1.3250 which I minimized and which is stable to 2x othos for >6 hours. I'd like to find out what the stock numbers are for the other voltage settings and see if I can minimize them after seeing just how poorly the auto setting for my CPU vcore was.

Here are the options from my v.1101 BIOS:

FSB Termination Voltage: Auto, 1.2v, 1.3v, 1.4v, 1.5v
NB Voltage: Auto, 1.25v, 1.35v, 1.45v, 1.55v, 1.65v
SB Voltage: Auto, 1.5v, 1.6v, 1.7v, 1.8v
IHC Chipset Voltage: Auto, 1.057v, 1.215v

Thanks in advance for any info and links you can provide.

[DL Drafting]

Thanks. If 4 Ghz is doable, then it sounds like it would be in the realm of water cooling at the least. I think I'll be well satisfied with 3600. So far it has been very stable and very fast. I was able to further lower the core voltage too, so things are looking good.

ok i need a bit of help here. i just bought my first intel in many many years and this overclocking seems a bit confusing with all the variables. first off heres what i bought.

p5b deluxe, newest bios installed
e6600
2x1gb kingston hyperx (khx6400d2llk2)
evga 8800 gts 640mb
antec sonata iii should be here next week.

without touching any voltages i tried 333x9 and 400x8 with the usual features turned on or off as per the guide here and other sites ive read. windows boots fine and runs for a while. but then a random program will hang, the window stops drawing itself, and if i try to kill the process it doesnt go away. and any other programs i try to start after that will not start. i also cannot shut down windows when its like this and i need to do a hard reset. doing a memtest with this overclock also gave errors, so i figured the ram needed more juice. i upped and upped it until i got to 2.3v and i didnt want to go any higher because that seemed high, and i still got programs freezing, altho after a longer period of time. so i figured i better start overvolting some other things. these settings are estimates because i dont want to reboot right now as im testing how stable it is (its been on overnight and its fine so far). the cpu is 1.3/1.4ish and fsb and nb are both at the first number thats purple.

so first ive gotta ask, that symptom of programs freezing like that, is that because of the memory only? or could it be the cpu as well? was i right in overvolting what i did? im really unsure of what i should do at this point.
thanks for any help.

You should list all your setting here, so we can try to help. What do you have ram freq set at? What psu are you using?

i have a 460 watt enermax psu at the moment, but that 500 watt earthwatts one is coming in my antec sonata 3 case, probably monday/tuesday.
too lazy to write it all out so heres some pics. i made them b&w for readability. i think its finally stable at these settings. but id need to run my system for longer to really know.

the lowest voltages you can choose are the stock ones. Can't undervolt them.

Hi all, I have a small problem with my overclocking. Currently, I have 3.2GHz @ 1.320Vcore, 1.45 NB, 1.3000FSB, 1.60 Sata, ICH 1.057 and it is stable with timings of 4-4-3-4-35-10-10-10-10. When I overclock to 3.4GHz at 1.4750 (set) and it not stable when playing BF2142, my keyboard lights would go off which means that my memory isn't working (2.25V). How do I get the right subtimings for my Kingston Hyper-X 8500PC2. I have an E6300.

Thank you

[ziddey]

well I'm assuming you're at 485fsb 1:1, which shouldn't stress the ram too too much. That said, if you're thinking it's your ram holding you back, you can try some looser settings to start.

4-4-4-10-4-35-3-11-5-13 may work better

that said, you can probably settle with 4-4-4-4-4-25-2-9-4-11.

[An0nym0us88]

Hi all,

I am currently running 3.22GHz for awhile and has been stable and I been messing with voltages:

Vcore 1.35
FSB 1.3
NB 1.45
SATA 1.50
ICH Auto

Timings 4-4-3-4-35-3-11-7-13.

Any recommendation to change any of these settings to be more safer?

[Wotanx]

Ive clocked my P5b deluxe to 3ghz idle temp is 37 and 50 whilst playing games

it is hitting 70 under loads using intel TAT and orthis

is this too hot ?

i had the chip clocked at 3.2 and it was the same temp my vcore is 1.35 although probe shows 1.32

[graysky]

@nasgul: you're running 9x350 w/ memory @ 4:5? Why not 1:1 with your ddr2-800?

[Wotanx]

Thanks for the reply


systems seems rock solid even though with the fluctuating voltage - i read up on the vdroop pencil mod but didnt quite get what i was supposed to do :P

im using an Artic Cooling Freezer pro 7 -

my paste is some old artic silver 3 i had knocking about

i know 70 is too high

but is 50 ish ok - cos it never goes above that when i play games only when i use TAT or Orthos

cant find anyone in the UK selling that cooler - can anyone recommend another ?


maybe i should change the paste too ?

[DL Drafting]

Here are some screen shots at 1:1 460 FSB x 8 multiplier 3680 Mhz with plenty of stability. The heat is at the upper limits, however, and I probably won't use this for everyday, but FYI for anyone who is so configured. Note that the Mem timings are the same as at 450 Ghz. That didn't change. Have a great day. Dan

Thanks ziddey, I will try that.

[karateo]

@Dan
why don't you clock more your memory? those sticks can go up to 1000+ cl4 vdimm ~ 2.3v i think

by the way, you posted the wrong cpu-z screenshots
1st fsb is 460
2nd fsb is 450
:p

[DL Drafting]

karateo,
I meant to clarify that 450-460 fsb pic. Used the same timings for both, but just took the snapshot of the 450. As soon as I get through testing the max bus on the 8 multi I will for sure work on tightening those mem timings as well as start to lower vcore, which now is at 1.5. Thanks.

[DL Drafting]

Have been able to move up with stability just a little further to 470. 1:1, 470 X 8 multi for a rated FSB of 1880. Temps are about the same as at 1840, can't really tell a difference. Still warmer than I would like, being at idle 41C/ 43C @ ambient 20C.

First off, sorry if this is a bit noob – as I am, and this is probably old hat too, but I’d like to get my system through what seems to be a 3.2Ghz barrier. I’m pretty sure it’s me and not my system, so I’d just like to prove that. I got to 3.2 with just changing the FSB and the memory ratio (4:5), anyhow my system:

E6700 Stepping 6 | P5B D (rev.C2) 1101 BIOS | 2x1Gb Cellshock 4-4-4-12 PC2-6400 memory (Micron D9GMH chips) | TJ05B Tower | 850W ENERMAX Galaxy PSU | 512MB XFX 7950GT 610M XXX | Various HDD – don’t ask.

My settings:

CPU Freq: 320 | DRAM: DDR2-800 | PCI Express: 110 | PCI: 33.33 | Spread: Disabled | Vmem: 2.05 | Vcpu: 1.2125 | Vfsb: 1.2 | Vnb: 1.25 | Vsb: 1.50 | Vich: 1.057

Ratio: 10 | C1E: Disabled | Max CPUID: Disabled | Vanderpool: Disabled | CPU TM: Enabled | Exec Disable: Enabled |PECI: Disabled

Memory: 4-4-4-10-4-20-10-10-10-10-Disable

I’ve loosened the memory timings (5-5-5-16) and upped the voltages (Vcpu: 1.2375 | Vfsb: 1.3 | Vnb: 1.45) in an effort to get beyond 3.2, but to no avail.

Can any kind soul point me in the direction of what settings I should fiddle with first to try to get higher clock speeds?

TIA

Richard.

[Viss]

More vcore perhaps? Try 1.35v for example to start with. 4/5 divider is much harder on P5B then 1/1 or 2/3. I would set pci-e at 100.
