ASUS P5Q-E (P45) pre-view

Yup, 1 of your sticks is dead, get in touch with OCZ and get them RMA'ed, your sticks should beable to do their rated speed at the rated voltage on any board divider, its not the board.

And the fact that I'm running beta bios 1101 shouldn't matter? Should I try another one?

You could try the offical bios, but I would be suprised if it made any difference, the fact that one of your sticks will go for 13+ passes and the other cant even manage 2, tells me that stick is knackered.

I am doing 500fsb on board stock voltages, well sorry they are set to auto in the bios, the only ones I have manually set is the MAIN memory timings 5-5-5-15, the MEM voltage and the CPU voltage, I am now playing and testing with the PL, just to see if I can tighten that up a couple of notches.

Please, note that stock voltages are NOT stock voltages if you set it to AUTO or even if you set manually each parameter to the right stock voltage; the mobo overvolts it for you. This is what happen with the deluxe and i think it can be the same on the -E version.
Refer to the "ASUS P5Q Deluxe discussion" for info.

Thanks I think I did read that. The only voltage I seem to be able to monitor within windows is VCore though. Is there a way to detect VDimm?

Mmmm... I think not. Asus board doesn't tell the voltages.
The auto-overvoltage has been noted by misuring each voltage with a multimeter directly on the board (deluxe). I don't know if the misuration points are identical on the -E version, but I think not.
There are some photoes on the deluxe topic about it.

LOL, thanks for picking up on this but its kinda why I corrected myself in the same sentance "well sorry they are set to auto in the bios" however, as long as the board isnt bumping any of the voltages itself into the red, then im very happy with what the board is doing itself, I was going to get the Deluxe version myself, however the only differences I can physically see on the deluxe is the 16 phase power, and the SB linked the the NB with a pipe, to me, not worth the extra £25 GBP.

As for voltages and temp monitoring, ASUS dont support it on their lower end boards, the only boards that ASUS make that monitor all voltages and temps, like NB, SB, PLL etc is the ROG series like the Maximus Formula's.

[Cloud76]

Sorry, I haven't understand your little correction about it.
I would know if someone find the misuration points on the -E version. The pcb is similar but not identical compared to the deluxe

[wongnog]

From what I've read I don't think anyone has used a multimeter on a P5Q-E to confirm overvoltage or not, but I'd say it's fairly safe to assume it does based on similarity to the P5Q deluxe and the fact that VCore overvolts.

But regardless, if I set everything to "stock" or "auto", in most cases those values are the minimum the board allows (e.g. 1.80V for RAM). If the board then overvolts beyond that, there's nothing much I can do about that.

Anyway back to my RAM problem, I tried 0704 and 0803 official bios but neither would even post using my old O.C. profile, so I didn't bother to try and reduce my overclock to make it I just flashed back to 1101. I seemed to have gotten good overclocks from that bios, and now that I'm in single channel mode maybe I can push the chip a little further (I was reaching an OC hole around 380 fsb before). I put in an RMA request for my ram on NCIX, so I'll wait to hear from them.

For example, if stock of vFSB is 1,20:
if you set AUTO it can gain to 1,55 and up...
if you set manually stock 1,20V it can gain up to 1,55
but if you set a little higher, 1,22 or 1,24 and so on it doesn't overvolt so much but only a little.

This problem isn't for vdimm or for vcore (but some users says that vdimm is higher of 0,1V).

note that with other voltages the reading is different from board to board, only auto and the lower are sure overvolted.

Thanks for the links, thats it, they are set manually now, that link from jVIDIA, scary, CPU PLL Voltage on Auto = 1.82v

Set NB to 1.3v, FSB to 1.3v, and CPU PLL to 1.56v, kept them a bit low to compensate for the little extra it adds itself and also to see how they go for starters.

did anyone else using the latest official bios have a problem with the board insisting on setting the PL at 5 when ever it was at auto?

[MonsterMan]

I had errors as well on memtest with bios 1101, went back to 0803 and memtest has no problems at all. So if I where you, I would go back to 0803 and test if that helps you.

Thanks I'll give that a try. HAve you noticed that your temps are inaccurate with 0803? I had read reports that temps are unusually low with 0803 but wasn't sure what to make of it...

[Wiggy McShades]

does anyone know what the safest for 24/7 on a 45nm cpu is for vtt, cpu pll, and vcore?


So far these are my results on the latest official bios under load with 1.3 vcore 1.3 vtt, 1.56 cpu pll, 1.3 nb. That's about as high as this cpu will do for fsb and maintain stability.



EDIT: what about GTL what's the percentage of the vtt that you are suppose to use for 45nm cpu's and the p45 nb?

When my PL is on Auto and I boot into windows and open up memset, it always says my PL is on 13, however if I then go into the bios and set the PL to manual, it initially appears as 5 until I manually set it, currently im on 12.

Most people wont set the CPU PLL higher than 1.6v however some will goto 1.7v, dont find out the hard way like I did by setting this to auto, otherwise the board will bang the full 1.82v through it. as for the CPU voltage, the gospel safe zone for CPU voltage is 0.20v above your CPU Vid, my CPU Vid (E8400) is 1.220v and I am banging 1.41v through it overclocked, just below the recomended, NB voltage I would say is pretty good up to about 1.55v-1.6v Max, but its gonna get toasty under there with that much voltage so aditional cooling will be required, As for GTL's, they are on Auto for me with a dual core, you can set them manually and get a tiny bit more out of your CPU, but to be honest I really cant be bothered with it for the extra I might or might not achieve, however they are more or less required to be set for good clocks on a quad core.

Would the same be true for a Q6600?

[Seanie's Show]

yes / no, sorry to be blunt, but you might need more NB and FSB voltage for the higher Quad clocks, as a quad core is harder on the board, and also will prolly have to set you GTL's which can be a complete and utter pain in the butt. as for CPU voltage, its never advised to go any higher that 0.20v above the vid for any CPU, and stick to 1.6-1.7v CPU PLL for any CPU also.

[wongnog]

Hmmm okay so what does it mean when you're 13hr prime95 + memtest stable, but crash after 30 mins of Crysis? I have a Q6600 (G0) on P5Q-E (1003 bios), here are some of my bios settings:

444x8
NB Strap: 333
DRAM freq: 1067
DRAM timings: 5-5-5-15
Performance Level: 10
VCore : 1.45000
PLL : 1.60
VTT : 1.40
VDimm : 2.00
NBCore: 1.30

I had the same problem with my P5Q. Try different PL settings. I got crashes when playing crysis with any other setting than 8. The same thing happened when I set vNB over 1.26 and it overheated, but I guess that it shouldn't be problem the P5Q-E since it has better NB cooling.

My PL is at 10, so wouldn't setting it to 8 make it more unstable? I'll try backing off on some of my other voltages.

Try any PL value, even lower ones can be better. I get serious unstability at PL10 or more. I'm very confused but I doublechecked it: 8 is rockstable, 9 crashes in 1-2 hours of Crysis, 10 crashes in 15 minutes of crysis and 11 or more crashes in 2 seconds of crysis.

[Seanie's Show]

Oh ya, and my PCI-E is set to 101. Should it be 100?

Yes PCI-E should be 100, but 101 wont make any difference really, basically your have overclocked the PCI Express bus by 1mhz, nothing.

Back to the PL thing hey, did you set your PL to 10 manually ?, if you set it to auto what does your system set it too ? if your having to set 10 now for stability in Prime and Memtest etc, then you definatly not gonna hit the 7/8's.

If Crysis is crashing then maybe its a P45 compatability thing, who knows, I dont play Crysis, dont like it, I see it as a slightly modded version of FarCry, and just been ripped, however have a look around, search google, see if anyone else has got the same problems, maybe there is a fix/patch for it, or even save you overclock to a profile space in the bios and load stock settings for everything then try Crysis again, this will narrow down if its the board or the overclock.
