That is kind of odd but, the hard drives stopped talking to the cpu with the whole CME Fiasco as well before they supposebly fixed it with their new BIOS revision so.. I find it kind of odd.

[FabricioGS]

Guys, help me out here please.

4250MHz (533x8)
vCore = 1.35000v
CPU GTLs = Auto
CPU PLL = 1.54 (or 1.56, don't remember)
FSB = 1.30v
DRAM = 2.10v (1:1) @ 5-5-5-15
NB = 1.28v
NB GTL = Auto
SB = 1.20
PCIe SATA = 1.60
CPU/NB Skew = Normal
All the rest: Auto

I guess the vcore is fine, but what about the 533 fsb and other volts? Is it too high for 24/7? I really have no idea what's safe to use

I'm either using this config or 500x8 with a bit less voltages, but with a 533 fsb I can use my mems 1:1.

[Martin.v.r]

PLL 1.52v
fsb 1.36v
NB 1.5+v

This is with my wolfdale. Its really odd. Everything else works fine, but its irritating having to wait an extra 30 seconds to boot into windows. Have you had any issues since this new bios update?

I wouldnt be worried I run my e8400 at higher voltages than that for 24/7 useage and have been doing so for a while now.

Thanks BababooeyHTJ. Now i'll try to find the higher clock it can run stable with 1.40 vcore just to know the potential of it. I'm loving this board and the E8400 ^^

[MADMAX22]

Interesting issue with my P5Q pro. I can get it to boot to windows and is stable at 500fsb. Anything over that I can run memtest and it will boot thru bios but when I try to boot too windows it crashes.

I had it at 533fsb running memtest just fine but try booting to windows and no go. I know the cpu and ram can handle the fsb upto atleast 540 if not much higher.

Is there anything that is required for the sata ports (which ones to be used), pcie sata voltage, or something similer that allows a high fsb to be used?

Thanks for any input.

Nope besides me having to switch to compatible everything has been fine.

[Godmyster]

I have a friend that has a Q6600 runing at 1.45v with a tunic tower is there any problems there? is to much voltage?

[CryptiK]

No that's fine. It would be pretty warm though.

[Godmyster]

Its not that bad actually its around 40º i can go up to how much vcore without harming the CPU?

[truehighroller]

I think 1.55 or 1.5? I think it has been awhile. I ran mine at constant 1.45 for my 3.6GHZ 24/7 air cooled with Thermalright extreme cooler when I had my Q6600.

[Diablero]

Hey People, i just finish to build my pc rig, and my Q9550 e0.

I have seen many wonderfull results, but i am wondering if mine is normal, i need more than 1,36v to prime at 450x8,5, and last owner of the same processor could do it with 1,22, i bought it from Pcc2iminal,
http://img148.imageshack.us/img148/8215/imagem1sc5.jpg. i dont know what i am doing wrong.

First i raised the fsb, i went til 470x7 with no problems (tweaking the bios a lot), but i can do prime and intel burn test just ok.


But when i raise the mult, the system get unstable, everything is saying that i need more vcore..., but i know this cpu dont need all this vcore.., my temps is ok, its a home made water cooler, priming 4ghz@1,4v at 62 full on cores, and 70 full on intelburntest (but it get unstable)...
I cant even boot, 3.87ghz@1,25v.., and i need 1,36v to get it priming.

What can i doing wrong?

Bios i am using is the latest 1406

My settings at 470x8,5:

Mem at 940mhz atm (OCZ 4GB 1066 REAPER)
Static = disable
training = disable
OC Charge = Auto
A.Clock = medium
PLevel = 10

vcore = 1,4v
CPU GTL 0.67 (both)
1.56v PLL
1.28v VTT
1.34v NB
0.64 NB GTL

SB 1.2v
pci-e sata 1.6v

LLC Enable

Cpu and NB Skew Auto.


...



BTW, mine is an L825B434

[CryptiK]

So Pcc2iminal said it did 4GHz prime stable on 1.22 vcore. What vFSB & vPLL was he using for that, and have you used exactly the same voltages? What board was he using?

He primed 450x8,5 at 1,22v, but i cant get the same with less than 1,37v, 4ghz is my particular clock.

Wow that's impressive. My Q6600 never even posted on bios above 489 fsb.

You've got a good chip there Amon

[BlindFreddie]

QX9650 C1 on A5Q-dlx, BIOS 1406, TRUE (lapped), fans UltraKaze 2000rpm push, Zalman ZF1225 pull
2x1GB Corsair Dom PC2-8500CS, Win XP-32 Pro SP3

My aim is a 24/7 setup for crunching on WCG (please join me at www.wcgrid.org).
I would like 4.0GHz or even 4.2, with minimum Vcore ... my electricity bills hurt!
Note: This chip is a C1, not C0. (How I wish it was E0)
I'm having great difficulty getting this QX chip to perform - much harder than with my Q9650.
Have tried Leeghoofd's settings from this thread (post #3583), but I need 1.38 Vcore to get as far as the boot menu with those, and it won't boot Windows.

Current setup:
392x10, Strap 333, PCIE 100, DRAM 392MHz (FSB:RAM 1:1), 4-3-3-12 2T other RAM settings Auto, but have used Memset to set PL=8 (7 seems OK, not 6).
Vcore 1.3750 (BIOS), 1.368 (cpuz)
VPLL 1.56, VFSB 1.24, VDRAM 1.98 (RAM specs to 2.1V), VNB 1.26
LLC enabled
CPU Margin: Performance (seems to have no effect)
Spread spectra disabled
C1E Support Disabled
(Leegh: When C1E is enabled, multiplier switches to x6 when idle - this causes me confusion and (?) might trigger a crash)
CPU TM: ENABLED
(Leegh and everybody: This is the Thermal Monitor function which will throttle the CPU if it overheats - I want it ON in case of a cooling failure!)

Other info: I can get CPU clock higher with x10 multi than with x9. Going to x11 makes only a marginal improvement. Increasing Vcore helps but not by much, and not enough to justify the extra power and heat. Severity of instability is less sensitive to speed than I've previously encountered. At this stage, I'm looking for max CPU clock ... I'll bring the RAM (and FSB?) up later.

I just discovered that increasing PLL from 1.54 to 1.56 has improved it so I can run 4xPrime95 for 30min+; with 1.54 1 Prime stopped after 5 min.
How sensitive is performance to VPLL? There's not much headroom between 1.56 and recommended max of 1.60.
Update 1: Just got another "Computation Error" on WCG, so it seems that VPLL=1.56 has not been enough help.
History: After running WCG OK for some days at 395x10, I started getting these errors. Never had this type before. Sample error messages:
Unhandled Exception Detected...
Reason: Access Violation (0xc0000005) at address 0x004C60C3 write attempt to address 0x000045C4
... others: at address 0x00000000 read attempt to address 0x00000000, at address 0x00A0BF6C read attempt to address 0xFFFFFFFF
No "Invalid" jobs. I'm wondering whether it's a chip problem somewhere. Have just popped out 1 mem stick.
Update 2: Mem seems OK. Upped VPLL to 1.58. Stable at 392x10. Boots Win @ 400x10 but 1 Prime of 2 stopped in 30sec. I think this chip is a lemon

Suggestions welcome, will try Leeghoofd's (next post) soon.
---------------------
General:
I note Leeghoofd's previous VNE (Voltage-Never-to-be-Exceeded) recommendations for 45nm CPUs:
Vcore 1.40V, VPLL 1.60, VFSB (aka VTT) 1.40, VNB 1.60 (I think for a P35 ... others?)
That should be in a prominent sticky, along with the rest of Leeghoofd's brain.

What about max temps for 24/7? 60 deg C?
(RealTemp seems to give the most appropriate values for 45nm CPUs - I think it just subtracts 10deg C from raw values)
Current temps running 4xWCG are room air + 17deg C = 40C.

Re. FSB:RAM ratios. In another thread, it was suggested that the only ratios other than 1:1 that were worthwhile are 1:1.25 and for DDR3, 1:2. There seems to be a penalty with a non-integer ratio.

Freddy I run now

400 x 10, 266 strap ram at 1002Mhz (4Gb kit), PL 9 and clock twister at moderate... you can also try eg 425FSB with ram at 1066mhz and 9.5 or even 10 multi... Ram timings don't play such a big role on Intel platforms then they do with AMD or Nvidia based rigs... so with ya current speed I would set at 4-4-4-12 or just the stock 5-5-5-15 at 1000mhz and beyond...

CPU Voltage: depends on your cpu I can get away with 1.2562 (LLC enabled)
CPU GTL Voltage Reference (0/2): 0.640
CPU GTL Voltage Reference (1/3): 0.645
CPU PLL Voltage: 1.54
FSB Termination Voltage: 1.2
DRAM Voltage: depends on ya ram, my board overvolts 0.08
NB Voltage: 1.24
NB GTL Reference: AUTO
SBridge Voltage: AUTO
PCIE SATA Voltage: AUTO

I'm happy with that, I can get more (ram)speed with a higher FSB but my CPU heats up then... comparison 400FSB and 450FSB is 8°C difference under load (both for 4ghz and max Vcore 1.3 tested) with 500FSB it's close to 15°C more heat... I settle for 4ghz and a higher multi and wack up FSB for benching or co... CPU will do another year at these speeds and if I need more, I give her some more juice...

I settle for 65°C max under IBT which is about 55°C under prime small FFT's for 24/7 ops... I take Tjcasemax 100°C just for my piece of mind ( even though it's 95°C for our CPU's )

Folder too here mate, good to see some good use of that raw power...

[BlindFreddie]

Re; My QX9650 problems ...
Leeghoofd: Thanks for your quick reply to my post above (#4574). You don't seem to have any great inspirations for me tho. I don't expect having to fiddle with VFSB or GTLrefs at 400MHz - my previous Q9450 didn't need VFSB until around 450,
I've copied my "Computation error" messages from WCG website, as this type of error seems to be unusual there and they may suggest a reason to someone here. I'll edit them into my post above, and I think I'll cross-post to the WCG forum here too.

(Your RAM at 1002MHz with FSB 400 is 1:1.25 where you had 5:6 before.)

THANKS FOR POST BELOW. Will take a while to try your suggestion, as I'm currently unable to spend too much time on it ... in short term I'll try to find a stable parking spot to run WCG between attempts at improvement.
I suspect it's a dud CPU [ ]
(I'll edit here and in post #4574 (2 above) rather than making extra posts, as they lengthen the thread for everyone else to have to read)

[Leeghoofd]

Each CPU is different sadly... what works for me might not work for you... just try 400FSB with 9 multi first... try to determine lowest Vcore, FSB , PLL voltage you can use... then work ya way slowly up... leave ram timings and co at AUTO to rule them out...

Start with 400FSB ram at 800Mhz, rest of the ram timings at AUTO

CPU Voltage: 1.3
CPU GTL Voltage Reference (0/2): AUTO
CPU GTL Voltage Reference (1/3): AUTO
CPU PLL Voltage: 1.52
FSB Termination Voltage: 1.2
DRAM Voltage: 2.0
NB Voltage: 1.2
NB GTL Reference: AUTO
SBridge Voltage: AUTO
PCIE SATA Voltage: AUTO

And try to get 3.6Ghz stable -- then up multi to 9.5 and just add some Vcore if required -- etc.. then start to tweak rams...

I use a few hours Prime small FFT's to determine Vcore... then run Hyperpi 32mb, some OCCT MIX and finally LinX or IBT... if that's stable up the multi... if it's unstable up a bit PLL , test again, then FSB, test,...

Genish plz back off to manual voltages plz (for PLL, FSB Term and NB voltage) for your CPU and plz improve the cooling of the CPU, the Zalman does not cut an OC'ed quad and best choice is the Thermalright Ultra 120...

Try these plz :
