I just got my box last night to 9x380 DDR2 890(I think), you think as far as multitasking performance that 8x400 @1000 would yield better performance, or would it be negligible?

mrt2,
I am just starting to play with performance testers, but I've been running at 435x8 with my dram around 1088 (not in front of my computer now so I can't be sure) with no problems.
People have responded and said I'd get the better perf with 9x380 because of the "strap", but I don't understand that yet.
Very similar setup to yours (e6600, P5B dlx, Corsair pc-8500 x 2Gb). No problems with heat.

What's the vdroop mod for this board?
I am wondering what a safe 24/7 NB V-Core, FSB Termination Voltage, SB V-Core, and ICH Chipset Voltage is for 400-450FSB? Thanks a lot guys.
Check mailbox!
MY Bios settings:
Vcore=1.5 V (24/7 )
Vnb=1.55V
Vsb=1.6V
VFSB and Vich= auto (these are the most stable settings here)
Note= 3.6GHz compared 3.2GHz requires more voltage (3.2GHz mostly needs 1.375V) and makes ur cpu go more and more hot (here idle= 55grade celsius).
Thank you very much. If I was to set the VFSB and VICH to something other than auto to get rid of the PCI-E x1 issue what should I use?
In here I've got mid'voltages :D
my 24h rig ( w/pencil vDroop mod done ) :
E6400 @ 515x7 = 3604MHz
vCore -> 1.4375v
vMem 1:1 -> 2.3v
vFSB -> 1,30v
vNB -> 1,45v
all other voltages set to it's minimum values ( not Auto )
^^Thanks, That is exactly what I was looking for. I mainly asked this because I have heard it is a way to avoid the stupid x1 issue I am having. BTW: I have a week 28A E6400 also:).
Thank you so much. This fixed the x1 issue I was having.Quote:

No, but setting all of those voltages to a fixed value sometimes solves the PCI-E x1 issue(it did for me).

what's all this talk about changing the memory ration to 4:5 or something. Where is this option to change the memory ratio????
i am on 1004 p5b deluxe
e6300
looking to push past 3.2ghz (current) on air.
^ just use the second option in DRAM frequency and adjust vdimm and all that accordingly.
Ima try a few of these out, since nstalling the P5B in after the DS3, overclock seems to be walled @ the same place 460 ish..
hi guys wondering if you could help. i did the pencil vdroop mod with 0.08 vdroop now with my e6600@3.6 ghz. no vcore volt mods.
ive reached a wall, can get over 410 fsb, can anyone help? what should be the nb, sb, and vcore @ this speed?(410 fsb * 9)
I finally got over 465 fsb with SB set to 1.7 is this safe for 24/7 usage?
I need 500 X7 badly and this is slowly working my way there..
vcore probably should be around 1.45v+. The nb and sb depends. I have my nb at 1.5v @ 500fsb and sb at 1.7v. Just keep trying different combinations. I must say though, 3.6 is already pretty good, so you might just about reached your limits.Quote:

Just me or are the pics dead in the first post?
Hello. New poster here.
I've run my E6600 on P5B Deluxe with following settings:
9,0 x 378MHz = 3402MHz
VCore 1,40V (1,375V was enough though)
DDR 2,1V
PCIE settings at 100 and 33,33MHz
Corsair 800MHz DDR2 mem at 4-4-4-12
Stable under Orthos for some hours and I didn't bother testing any longer. In P180 case with two S-Flex 120mm fans @1000rpm and Tuniq Tower 120 @1500rpm. Reasonably quiet (no sound heard from under the table while music playing).
Measuring with Everest Ultimate I have cores temps ranging from 33C to 55C depending on load in 22C room temp.
I would like to push for 9,0 x 401MHz. Some say that 401MHz is easier than 400MHz because of some strap thing or something else which I didn't really get. I'm back home tomorrow and will try the higher voltage settings given in this thread for chipset.
Any tips how much VCore should be a good bet to start trying to achieve stable system at 9,0 x 401MHz? DDR should run without problem at it's specsed 2,1V at least to that 800MHz. The other voltages, I've understood, one can set pretty freely to the max values?
Maybe a little more vcore. No need for other voltages to be at max with only 401fsb, lowest settings should do.
Oh sorry, I forgot to add that I tried 9,0 x 401MHz earlier. Same settings but VCore 1,425.Quote:

I'm running my E6600 @ 3,2Ghz (8 x 400) but after 4 to 5 hours of Orthos (blend aka. cpu & ram and priority 5) the system hangs, no crash, no reboot. Just hangs - no mouse movement.
Also, when using this settings my system isn't 24/7 stable, anyone can advice me what settings I should take to change this situation ? I have vcore @ 1,35v so I'm around 1,3v in Windows under load. Would a higher voltage on any other component help (most things are on auto there).
I have my Corsair memory at the default 5-5-5-12 as it is 6400 C5.
Thx.
ps. from what I can see (CoreTemp, Speedfan) temps do not pose a problem (below 60 degrees)
Try going to 401x8(thats when the strap changes to 1333) as the system might not like such a high speed on the 1066 strap.
Just showing off this stock P5B-Dlx (only vcore mod) @ 560fsb,vmch 1.65V...

Jeez and i thougt mine was good @ 560:D
Great fsb for stock mobo m8:cool:
The BIOS settings on page one did not work. I configured the system frequency/voltage and the pc shut down and would not boot back up. So I unplugged it and got an overclocking failed message. I had to set the AI Tuning back to auto. Also, any idea on how to get rid of the beep during power up. It has been doing this since I put the pc together. When playing games like Half-Life2 I get a beep or two during game play. I have the most up to date BIOS. Why is this? Could this be a memory problem? I ran Memtest and it checked out fine. I am worried about damage to my PC.
Here are my specs:

Thank you.
My setup is able to reach 3.5Ghz at 500mhz default multy. It requires just 1.38volts with the vmood applied on the mobo to reach this speed. However just 1 more Mhz on the fsb and I will fail orthos almost immediately, with 5mhz more my computer will re-boot.
Something that I notice in my setup different than what you guys recommended here is my VIHC voltage; auto and minimum fails instantly at this speed, it requires 1.207volts (Highest value at the bios) to work correctly. Can we draw some conclusions from this? Where is my problem mobo or cpu? Am I doing something wrong?
Not sure what is going on. Cant seem to get settings right. My Ram Timing is supposed to be 5-5-5-12. I cant even get Orthos to run stable at 3.2 ghz. I think It has something to due with my dramm and memory voltage. Ive tried alot of combos. What im trying to achieve is 3.6 ghz running Orthos stable. I have a scythe heatsink no problems there. Just need to know a good set of settings to try.
What DRAM Freq to get 5-5-5-12?
What Mem volt?
What cpu vcore for 3.6 ghz stable? 400x9
Ive been leaving everything else auto.
Bios version 0711
Okay, I suck at this. I thought this would be easy with the P5B after reading 1000 forums and how-to's but damn. I have a hot running 6600 - first problem. So I can only run 3.2 (350 FSB) and keep my temps under 60C with my Freezone. I'll settle for that (for now). Eveything is on auto except PCI bus at 33.3 and DRAM V at 2.25 and it runs great. My SuperTalent memory runs at 3-4-3-8 with 266 bus but at 350 the minute I change ANYTHING else from auto it craps out. I have an XFi and an x1900, 2GB SuperTalent DDR800 and a Tehermaltake Toughpower 700, and P5B Deluxe.
Anyone willing to talk a retard through this?
Lower your multi and try FSB 400 or 401. Do not leave the voltages on auto. Set them manually when overclocking.
Try vMCH: 1.45v, vFSB termination: 1.4v, vSB: 1.5v and disable everything in CPU Function except PECI and Execute Disable Bit.
Also do net let the memory on auto. Set the latency manual, relaxed ones if you're going to go up to 800Mhz if FSB is 400.
reason you could be running so hot is because you left voltages on auto. If I leave cpu vcore on auto and run at 3.2ghz, it'll be feeding it 1.60v. Yikes! It only needs 1.325v.Quote:

Just started messing with my OC and thought I'd share my results.
8 x 401 - 3.2ghz at 29c Idle and 40c Load :rolleyes:
FSB = 401
PCI-e = 101
PCI Clock = 33.33mhz
Spread Spectrum = Disabled
vMem = 2.10v
vCore = 1.35v actual reads as 1.296v thats a lot of droop
FSB Termination = 1.3v
NB = 1.25v
SB = 1.5
ICH = 1.057
It was my goal to hit 3.2-3.6ghz on air. I haven't tightened up my ram timings yet. Still trying to get everything else dialed in before I do that.
Thanks for your answer ziddeyQuote:

I'm stable with an E6400 currently at 3504MHz (438x8) with 4-4-4-12 1:1 DDR2-875. Memory is PC2-6400 G.Skill "HZ" D9
24 hours in Orthos. Needed 1.44v under load, though. I think it's set for 1.50v in the BIOS, 1.44v load/1.45v idle.
Okay I am setting all my voltage manually and it boots to Vista 32 at 402 x 9 (6600). Works but is unstable. I load Speenfan and it says my Vcore is 1.12 even though it is set for 1.45 in the BIOS. Can't Vdroop that much can it? Where in the BIOS do I double check that I have turned off throttling on the CPU?Quote:

1.12 sounds like you might still have c1e/speedstep turned on.
speedfan shouldn't have the high voltage bug of cpuz. get aisuite if you wante 3 decimals like cpuz. that's incredible if you're seeing 1.12 and still able to boot, even if it's unstable. perhaps do the vdroop pencil mod. it does wonders
c1e is off. I'm in Vista now. I run Everest toture test and temps go to 67 on CPU even at 1.12 but I seem more stable since I turned off PECI. I'm thinking the Vdroop mod is a waste cuz it'll just give more heat right? What temp would you consider max? I hear keep it under 60. I have a freezone - I was hoping heat wouldn't be a problem.Quote:

well "sb vcore" starts off at 1.50 whereas nb is only 1.25v.
I haven't charted into 500 on this board yet so I can't say anything specific. What are you using to cool the nb? Perhaps try putting fans resting above nb and sb blowing down and see if you gain anything. Or if you've gone aftermarket for nb, try putting the stock nb heatsink on the sb.
It sounds like you might need a vich mod though for more juice. have you tried a higher pcie? both freq and voltage (vcore sb)
That’s a good suggestion, a good fan son the SB may be the solution, and perhaps reseating the heatsink will help somehow. I'm using stock heatsinks in both the NB and SB. Also the impression is that the mobo can not keep up with the cpu, because it can reach 3.5 with just 1.384voltsQuote:

I agree with you 110%, but I feel that my CPU can delivery more than 3.5Ghz. Anyway the problem could be the mobo itself because sometimes this P5B is a little bit funkyQuote:

Mem V 2.35 (verify this with a dmm to make sure you're getting something that resembles what you're setting)
Cpu V 1.5125 (definitely would look into vdroop mod. there's a real simple pencil mod, and if you want to take this to aim or pm, feel free)
FSB V 1.4 (1.4 should be good but you may want to try 1.45, at least for testing)
NB V 1.25 (you'll probably need a bit more voltage than this.. try for 1.55v if you've got decent northbridge cooling. try putting a fan on top blowing down for now if you don't have anything else)
SB V 1.7 (you should be able to get away with only 1.6 but 1.7 is fine for now)
ICH V 1.215 (the lower one should be fine for this but if this voltage is working for now, might as well leave it during testing)
i noticed you had some decently aggressive memory timings. try 5-5-5-15-5-42-13-13-13-13 for now. that's a really loose timing to try and should keep ram in the clear for a while longer.
from what I remember, when I was setting 1.5v, I was seeing something like 1.38v under load. I think I might have had particularly bad droop, but the mod (I shaded for a full minute and then blew the loose graphite and got 5k ohm resistance and now I have 0 droop as well as 0 drop. killed two birds with one stone)
the p5b is a fantastic board. don't lose faith. although your current overclock is already fairly decent. from looking at it again, it definitely sounds like youre probably not getting enough vcore at load (as mentioned, droop is really painful)
Am I right to assume that if I can run a certain fsb at a lower multiplier, then vcore would be the only voltage I'd be looking at when I tried increasing the multiplier?
For instance, I'm trying 7x450=3150. I'm able to get away with 1.40vmch, 1.20vfsb, 1.50vpcie, 1.057vich. Would stability here confirm that these voltages are fine for 8x450=3600, where I'd only have to worry about vcore? I'm pretty sure for all of them except for vfsb, but since 450fsb is already confirmed at 1.2vfsb and 7x multi, I figure 8x should be same, no?
Probably yes but why dont you just try it? You should be able to run up to 500 with voltages at lowest after auto.
your post is what makes this board rock. thank you very much.
I guess i have some work cut out for me, will report back when done. but yes, i see lower vcore and vmem already using asus utility. those 2 mods seems a must if you want top oc.
Hey all. I am currently hitting wierd ceilings with my P5W DH board (380 mhz FSB wall, even when lowering multiplier and adjusting voltages, and the Ram wont go past 950mhz (a common issue on the P5W). Also, my motherboard temps were getting VERY hot (38C without an external huge fan blowing into the system, and I have a third party cooler on the NB!) Also, does anyone know WHAT the damn MB temp sesor is measuring? Is that NB?
So I have decided to try a P5B board to see if I can get the most out of my e6700 and super expensive low latency OCZ titanium ram.
I have read the first 50+ and last 50+ posts on this thread, and my question is simple: What is the current most stable and trusted BIOS update for all you guys pushing this board at 400+ fsb? The newest on ASUS's site says that if I install it, I can NOT go back to an older one, so I hesitate to get it without knowing.
Also, what do you guys think about me switching from a P5W DH to the P5B? Is this a stupid choice, or is the P5B truly a better board to reach higher FSB?
Thanks for any info!!
I've been using the latest without much issue. Seems like asus bioses in it's current iterations aren't as flakey as older gigabytes for example. And I remember seeing that warning too and being afraid, but I could swear I remember reading somewhere that you can still backflash but only in dos possibly
I'm hitting a very HARD wall at 481. It's driving me nuts.
System specs in sig.
I have been running ROCK solid at the following settings.
460x7
1.32v Vcore
2.2v Memory Voltage
1.3 FSB Termination
1.45 NB
SB auto
4-4-4-12 timing.
Bios: 7011
to find my FSB:
I lowered the multi to 6, My ram can do 500+, already tested it. I loosened the timing to 5-5-5-18 just to be sure. I've already tested the ram to go past 500Mhz. Its Micron D9-GMH.
Upped my FSB Termination to 1.45
Upped my NB to 1.65
I can post at 480. But at 481, NOTHING.
It's just BAM! a wall. What gives :(? any Ideas?
Tried increasing volt for SB? Could be max your cpu wil do with the cooling used though.
yeah when you are stuck and SB volts increase isnt helping you need VMCH vmods im afraid+120mm fan. ;)
I doubt it's the max for the CPU. I mean, i'm hitting 3.2ghz stable at stock volts for CPU.
the extra 100-150mhz at even 1.42V cannot possibly be the max.
I'll try SB, what should it be? 1.6?

on a side note some high end ram is finicky about booting with the default 1.8vdimm so you may want a cheap stick of ddr2 to get booted so you can change vdimm. i don't know how many people have thought the board was doa or died just because the ram won't post. if i clear cmos i have to use a stick of different ram to get it to post but once i up the vdimm i can put my good sticks back in.
Max FSB it wil do, not same as max mhz cpu is capable of (although on 965 boards it means max cpu because lack of divider under 1/1 or async possibilities).Quote:

Hitting 480 on a 266 chip and it's still not good enough. I "hit the wall" at 356 and to tell the truth, I'm quite pleased with it since I got 3.2 gig out of a 2.4 gig chip. Basically a $1000 chip for $300. I consider that quite a good deal and it sure doesn't drive me nuts.
I hope you're not losing any sleep over your "problem". Heh heh
any performance increase when changing the bios settings from IDE to ACHI or APCH or whatever the hell it is?
Well, its not that.Quote:

I'm happy with my e6300 at 3.2, but i'd still like to see how people are getting 500+ fsb? That is all
The CPU works totally stable at 3.8 GHZ, I have narrowed down the problem to the mother board.Quote:

The CPU is water cooled, and even using CoreTemp for max readings, I only EVER hit 58C with full Dual Prime95 load, so I doubt it is the CPU overheating. The Ram is rock solid, tested with memtest.
So, the only thing I can think of is some sort of Wall on the P5W DH, which is why I am seeing if I can break that wall the with P5B. If I can, then you are right, the increase in speed to both the CPU and RAM will far outweigh any minor differences in the 975 compared to the 965.
I mean, I spent friggen $300 on this water cooling setup.. I want to break 4.00 GHZ! and I wont let any silly P5W board stop me!
Am I just nuts?

I couldn't even get 400 fsb stable. Consider yourself quite lucky as not all systems can hit what you have (if fact I'll go as far as saying MOST will not do it).Quote:

I can comment on this as I have done it. If you are not running in RAID or your SATA hard drive does not have the NCQ feature, then there is no performance benefit or difference.Quote:

As I have posted already a few times, I have a PHW DH right now, and with the FSB set to 380, I get a wicked hot North Bridge temp. (Especially given that I have to pump up the MCH to 1.75 to achieve this)
I have an aftermarket north bridge heatsink, and the real question is, how does the heat in the P5B north bridge compare to that of the P5W?
Also, does the BIOS give me diff temp reading for north and south bridge?
As I said before, all I want is to run at 4.0 GHZ with my 6700, so thats only 400 FSB.. (Although i saw on this thread that 401 is better because of wierdness)
What are some of your guys NB and SB voltages set to on your 400+ FSB settups?
hello, well i have a p5b delx and a 6300 L2, and well ive seen all over clocks and all but im rather happy at 1:1 fsb @400mhz, so at 2.8ghz im a happy camper =). now the problem is that since ive been reading a lot and tuning my rig, i did notice, that if u overclock the fsb and leave the v.core voltage at auto it can get into very high voltages (1.5 etc) now i dint like that so i managed to make my rig stable @2.8 with a 1.35 on the v.core. now my question is.. will the nb sb voltages if set to auto would change to very high voltages like it did on the vcore? if so, i would really like some help on determing the right voltages for my rig. Another thing i would like to know, what is the base voltages for the nb, sb and the vhcm, i know for the proc is 1.35max and for my memory is 1.9
thanks for your help.
yes set to auto they'll rise. unfortunately in the ds3 there's no baseline setting for some stupid reason so the best you can do is +0.1v
Hi, thanks for the fast reply!Quote:

ps: is there any program i can use to see these kind of voltages (sb, nb ect)? cuz ive tired asus probe 2, speedfan. and no go..i only get the vcore, +3.3, +5, +12, CPU, MB readings.
oh whoa i'm a little stupid. i opened the ds3 thread in a different tab and didn't realize i was looking at this one.
fcg, or anyone else, I didn't want to start a new thread so I figured I'd ask the question here.
fcg, I noticed you made a picture in another post showing that 1:1, 4:5, 2:3 on the 1066 strap but 3:5 and 1:2 from 800 strap. I was wondering if you knew of the dividers available in the 1333 strap?
Should getting an OEM P5B Deluxe make any difference on the board itself?
I know that all the extra cabling etc. is not there, but if the board is inherently different, that will piss me off.
Board itself is no difference. 100% identical.Quote:

Many thanks for this nice thread.
I ordered my P5B Deluxe and E6600 yesterday, quite anxious what Ill be able to get with my Teamgroup Xtreem CL3 DDR667
I've recently OC-ed my rig to 2.8Ghz and let it dual orthos over night..
The E6400 was running @ 2800Mhz and the Kingston DDR800 wich are default rated @ 5 - 5 - 5 - 18 @ 1.8v were running 4 4 4 10 1.9v DDR800 1:1 .. i let it run for about 8 hours dual orthos .. everything was fine..
After i stoped it i've decided to see if it can get some more.. (Note : the vcore was 1.325v manually set .. and the vmem 1.9v .. while the others on auto) I rised to about 3.2Ghz (400x8) and kept the ram settings unchanged.. 1:1 .. it ran dual orthos for about 30 mins again.. and at some point it died.. some nasty pop sound camed out of the mobo.. and a burnt smell.. I sent the mobo back and they replaced it without any comments.. my question is .. Did those auto settings in voltages pump too much voltage in the north bridge? since the only thing that died was the mobo.. and i have the feeling that while i was rising the freq in windows .. the mobo kept upping the voltages.. cand any 1 explain this ?
did you look to see what burnt?Quote:

I'll soon be on board with the P5B Vista edition. All solid state capacitors! hope it OC's as well as the others.
I was reading the data from intel on 965 chipsets and it says the max voltage for the NB is 1.375 !?!? How well does the chipset take xtra volts and what should my "real" max be?
I asume it was the NorthBridge :confused:Quote:

Lowest settings on the chipset voltages are good for me up to 410FSB. I can't get past 420 because of my RAM...
P5B Vista has 1.65v max on nb.Quote:

So I've read most of these posts, and found I was also having the X1 issue with my PCI-E and didn't even know it. I tried several suggestions and this is what worked.
Some say, don't go over 1.55V on the NB and some say they can't go even that high before they see the issue.
I think it is all dependent on the type of card you have?
I have the Sapphire Radeon X1950XT 256 and I did the following tests.
My PCI-E frequency is at 101, NB Vcore I tried at both 1.55V and 1.45V, in which case, they both worked to give me 16X pci-e in cpu-z.
If you're seeing the X1 in your cpu-z, reboot, set the NBvcore from auto, to 1.45, turn off your PC, turn off the PSU, wait a few seconds, then turn your PC back on. If still you have the X1 issue, then do the same steps but try 1.55V on the NB and so on.
Hope this helps.
FWIW, I was seeing x1 at first too. I bumped up to 1.55v from 1.25v and it went right up to x16. Ever since, I've been back down at 1.25v and it's maintaining x16 now.
Well through three successive voltage jumps I can't seem to penetrate 8 x 480 (3840Mhz) on my e6400. This is while load temps are at 64c on air. The voltages jumps have been 1.51 to 1.52 to 1.53. Anyone want to offer any advice? Here are the settings...
Advanced Tab
PCI Express Frequency - 115
PCI Clock Synch – 33.33Mhz
Spread Spectrum – Disabled
Memory Voltage – 2.25
FSB Termination Voltage – 1.4
Northbridge Vcore – 1.45
SB Vcore – 1.6
ICH Chipset Voltage – 1.215
CPU Config Tab
C1E Support – Disabled
Max CPUID Value Limit – Disabled
Vanderpool – Disabled
CPU TM function – Enabled
Execute Disable Bit – Enabled
PECI – Disabled
Memory Tab
Ram is not being stressed, I have PC8000
However, Static Read is Disabled and Peg Port Config is as follows
PEG force x1 – Disabled
PEG Link Mode – Auto
Asus CGI – Disabled
Having CPU TM and Execute enabled helped me gain a few Mhz in short orthos runs
