Also, let us know how 901m does

I won't make any further changes until some feedback is recieved.

They might be pulling the option out real soon that is all I will say....... Ket I pmed you.

The only way I see this working is if he writes original BIOSes from scratch.

Didn't think of that! Perhaps Ket should get a job at Asus....

Aaah so the half multi is a known issue - well, glad (in a way) that i'm not the only one to have experienced it.

Currently, running orthos at 420x9.5, 1.4250v and it's stable 21 mins in, whereas 445x9 wasn't (same settings otherwise, vtt, vMem, vCore, NB)...the BIOS's that are newer than the 1306 i'm assuming are Beta's?

Oh and whats CPU Margin Enhancement?

A

y option that is forking stuff up for Q9450 users and maybe,, other Quad users.. You have nothing to worry about if you are using a dual core.

The purpose in CPU Margin Enhancement is to help provide better FSB clocking with cheaper C2Ds.. that is, according to intel. In practicality this option only seems to play absolute havock with peoples systems. If you are experiencing odd system instability, not able to get FSB clocks as high as you could, or having strangely low DRAM frequency barriers I strongly advise you try one of these P5Q Series mBIOSes. The pack contains modded BIOS files for all P5Q series boards using code before asus added CPU Margin Enhancement.

That should explain it

Are the reported problems with Q9450 ONLY occurring with those, or on the Q9550 as well? I'm currently losing sleep over an upgrade decision on Q6700 or Q9550 (with P5Q Pro)...

Are the 45nm quads more trouble than they are worth compared to the older models?

**truehighroller** · 10-01-2008, 08:27 AM

I say get the 9550 and stick to a BIOS that doesn't have the option on it and you will be happy.

They will be removing the option very soon at this point any way so problem almost solved.

**Ket** · 10-01-2008, 08:40 AM

There is going to be a new set of BIOS files I will be releasing in a few days hopefully, quite heavily modified. These files will NOT be the "uber BIOSes".

**truehighroller** · 10-01-2008, 08:50 AM

Picture is worth 1000 words,,

**Ket** · 10-01-2008, 08:58 AM

1403 works for you? If thats the case, tell Asus to bloody hurry up and churn out a 1403 for all the P5Q series.

**truehighroller** · 10-01-2008, 09:04 AM

It works with my Q6600 that is the key note my freind , that is the key note. You know what this means right? My Q9450 has been damaged by this damn setting.......

**Ket** · 10-01-2008, 09:39 AM

Bad Asus. They didn't put CPU M-E in the M2F BIOS and that board uses a P45 chipset, so why did they put it in the P5Q Series? At the very least Asus should have thoroughly tasted an option such as CPU M-E before releasing a BIOS with it in

It's highly dependent on your setup. I see no issues on my p5q-e with my q9450 & newer BIOSes like 1201 and 1402.

CPU and NB clock skews affect the cpu and northbridge respectively. When you increase the FSB, especially above 400, the clock begins to drift, and the clock skew setting allows you to pull it back a little. This can aid stability. With wolfdales, anywhere from 100 - 500ps delay can help, usually 300 - 500 get the best results. I'm not sure about quads, I've never owned one. With the NB clock skew, it can be used in conjunction with the cpu clock skew, but it requires less adjustment, usually 100 - 300ps works well.

The 'Pull-ins' relate to memory channel phases. Enabling the phase pull-ins theoretically reduces the latency and increases the performance a little, kind of like reducing the PL but not as strong an effect. However, I have actually found that on my P5Q-Deluxe and Maximus II Formula the pullins do absolutely nothing.

Thank You for that information, it does help some and is appreciated

fwiw clock skews can make all the difference with quads too. unlike my gigabyte ep45-ds3r i don't need to adjust clock skews to get high clocks on the p5q-e, but especially when OCing memory they do come in handy. the only trick is to get a 50ps interval on p5q boards you have to adjust the dimm clock skew as well as the cpu and nb skews, since the latter 2 only have 100ps intervals on p5q boards. regardless you might find they help you squeeze out the last few mhz you're after. in some cases they might even help you achieve lower clocks with less volts than with skews on auto, so they're not strictly for OCs that push the limits of your hardware.

edit: found a nice light explanation of clock skews that helped me understand them better ... http://www.overclock.net/faqs/119265...save-your.html

**cka3o4nuk** · 10-01-2008, 03:02 PM

ppl can anybody upload somewhere bios seting for p5q-e and e8500 e0 higt overclock? (espesialy interested in gtl and vtt and northebridge) oc 4.5 or higher for m1402 bios?

**Ket** · 10-02-2008, 01:38 AM

Uh-oh.. Cryptik.. its one of "those" people

**Ket** · 10-02-2008, 08:29 AM

BIOSes removed.

**Dee** · 10-02-2008, 08:53 AM

Hi Ket. What's the reason for setting CPU Margin Enhancement to Compatible?

**Ket** · 10-02-2008, 09:18 AM

Theory is it'll enable the BIOS to act more like the versions before CPU M-E was added.

**Dee** · 10-02-2008, 09:36 AM

OK, P5Q-E 1402m is scary. You might need to pull it down before anyone else tries it.

Loaded defaults on 1302, rebooted, Flashed to 1402, system rebooted, entered setup and set defaults, tried to save and reboot, and it rebooted to a blank screen. Got scared, thought my system was screwed, but managed to reboot properly after turning all power off. Rebooted, entered BIOS, it was back at stock settings. Entered defaults, tried to reboot, system froze. was able to boot after turning power off again, but got "Press F1 to restore BIOS settings" screen or whatever it is. I did that, and entered BIOS again. Settings were back at default. 1402 will not save BIOS settings and every time I try to get into Windows with defaults, I get "Press F1 to recover BIOS", blah.

I'm all for adding more memory and CPU compatibility Ket but I think maybe you went too far with these! I'm not sure about renaming stuff in there anyway, I'd rather keep the original names for stuff... call me old fashioned if you like, but it's kinda pointless renaming it to Xtreme Clocker. My OC's are not very extreme anyway!

**Ket** · 10-02-2008, 10:16 AM

I renamed it just because "Ai Tweaker" sounds a bit gay

I'm not sure why the BIOS acted weird for you, its only mostly been minor layout changes. Did you properly reset the CMOS after the flash? (remove power cord and battery etc)
