Bloodrage P09 bios

[Mescalamba]

i can boot at 103 with G25... you HAVE to increase vdimm when increasing vtt??? what??? LOL
are you sure? what happens if you set vtt to the same as vdimm? vdimm gets increased automatically?
and if you reduce it, vtt gets reduced as well? 0_o

Lucky you (lol) for me it didn´t work, I got no-boot at 103, now it works. Well, it doesn´t get increased automatically, but when I tried to not increase it, simply it doesn´t boot..

+300VTT and 1.65vDimm resulted in no-boot (even +280)
+200VTT and 1.65vDimm is ok
+300VTT and 1.75vDimm, ok boot.. (tough, my ram doesnt like it)
+440VTT (or something similar) and 1.85vDimm .. booted, but ram gived up.. only one stick working with terrible mem errors..

[PiLsY]

1.80vdimm is working well for me. Anything below is a no post with over +260mv vtt. Assumed this was peculiar to my setup - maybe something you can reproduce? Have gone no higher than 1.80vdimm and dont intend to, although these sticks (D9GTS) should be good to 2.1v or so. Managed 6-6-6-14-36-1T @ 1662mhz so far by using XMP profile and 8x mem multi . Can't seem to get Cas or TRP lower than 7 to boot setting manually though. TRCD 6 works fine.

Reading all this about high vDIMM v is making me wonder ....... what is the best difference between vdimm and uncore for all your oc's ? i'm finding 0.4v is best but i'm wondering if anybody else is using anything differnt

[Mescalamba]

0,3V - 0,5V for me.. .. lower is stable for me too.. I had 1:1 on P06 BIOS without issues, but I´m pretty sure its not healthy for IMC.

0,3V seems most stable, and its probably safest.. 0,5V is fine for me, but cause both VTT and vDimm reading from mobo isn´t accurate, I prefer tighter..

I think that your 0,4V is probably best of it..

1.8V and my rams cease to work.. they are 1.5V to 1.65V max.. They can survive more, but its not stable..

As long as you keep good VTT:vDimm ratio.. nothing to worry about.. tough for 2V you would need probably at least 1.5V VTT (or little bit more, cause BR is undervolting VTT slightly). But 1.8 - 1.9V should be fine..

CL6 - 1600 MHz is actually pretty good.. but you have one of best OCing rams.

Cheers mate, gonna try P09 over the weekend ........ did try it last night but didnt like it Now i'm on P08 and have my system fully stable. Found that with P09 my vcore was all over the place
Will try different v range of differnce between uncore and vdimm as well to see if it helps

[saaya]

have you guys tried to increase vtt step by step to see if that helps?
i can run 1.1v vtt with 1.6v vdimm on G25 without any problems... thats actually the default setting...
.5v diference between vtt and vdimm is the max intel recommends, lower diference = better and ideally both voltages are the same...
that doesnt mean you should bump up either vdimm or vtt beyond whats necessary just to have them identical or closer to each other though

that high vtt doesnt work anymore unless we increase vdimm sounds very odd...
could it be that this new p09 bios is based on a more recent intel MRC code block? could be that intel somehow tried to force people into running vdimm and vtt closer to one another? i cant imagine qf engineers did this on purpose, its not easy to implement something like this and if they go at such lengths theyd rather implement a much easier thing like vdimm and vtt automatically adjusting itself if one of the two gets increased beyond a certain point.

vcore is worse for you oogie?
same settings as on G25? cXe disabled etc?

[Lord Trident]

please remember the VID voltage table change around G25 which is why you have to use increase voltage the old table had a lot higher voltage underload
the new table is a lot lower, p08 is using old table and p09 is new table.
so all you people scare of the higher volatge dont be the table from intel was putting in a lot higher that you did not know about
as long as you keep them temp down you are fine

thanks

Hi saaya

Yeah vcore was doing strange thing, with vdrop disabled it would increase itself by almost 0.15v and with drop enabled by 0.05v. Its quite a lot as dont have that problem when running P08. cXe disabled
On P08 onlly way i can get x21 is if speedstep is enabled

[Mescalamba]

I needed Speedstep + PPM enabled on P09 for x21 too.. CXE disabled.. voltage seems lower than with previous BIOSes, eg. BIOS setting sticks to what I set.. which is nice for me.

But its only what mobo says.. not sure what real voltages are.. but good is, that with default.. max with or without vDroop is vCore 1.25 (which is I think default right?).

[PiLsY]

Just so you guys are aware ive found turbo works at 18x multiplier. I can boot at 18x (confirmed by post screen) and as soon as windows launches im at 21x.

It let me do this: http://valid.canardpc.com/show_oc.php?id=677022

18x is my best multi for fsb clocking, and it looks like i may be able to max out the cpu at around that speed .

Not sure whether to go for stabilising this now or to leave that for the end and sort my ram and uncore out now. Running prime atm so ive got 10 misn or so to decide :p.

Great news! That looks awesome.

[Mescalamba]

Very impressive for C0.. going to try it.

[PiLsY]

Nearly there.....this is Linx and hyperPi 16 thread stable. Gonna go try Prime now.

Unfortunately my temps in Linx are getting ridiculous now. I cant stabilise anything over 4.48 at the moment, although I have validated at 4.6ghz but BSOD and reboot and the validation file wasnt saved (had to run in diagnostic mode to validate successfully, but therefore couldnt publish direct).

It was FAR too easy to get over 2000mhz ddr3. The gigabyte board wouldnt even entertain posting at these sorts of speeds.

A bit of oddness with manually set ram timings means im having difficulty getting it to post with anything except Cas 8. Switched to by SPD which is actually pretty good .

http://valid.canardpc.com/show_oc.php?id=677421

Also confirmed all multi's when set in bios boot and apply turbo to 21x when in windows.
PPm Enabled
EIST Enabled
cXe Disabled
CPU Turbo Mode Enabled
Multiplier 12x to 20x tested 920 c0 step.

All post at bios multi then apply 21x when entering desktop (Windows 7 RC-1 x64).

Can anyone else confirm this? Im sure my gigabyte board never used to do this? Made life a lot easier though!!!

Can anyone explain the second IMC setting? Options are Independant , Mirror, Lock or spare (or something along those lines). Ive no idea what it does so ive left it at independant.

[Mescalamba]

1.6V.. what you have? Phase change cooling? Or you are suicidal runner like me?

No clues about IMC.. tried Google? I wondered about lot of BIOS features.

[saaya]

nice find pilsy hehehe

i thought it was normal that no matter what multi you boot at with turbo enabled you get 21x in windows... other boards dont do that?
for me 19x works better than 18x for high bclocks

about the imc setting your asking about, thats a setting for servers and somehow changes the configuration of the imc slightly. its supposed to only affect DP and MP systems with numa, but i told the bios engineer to keep it, you never know, one of the settings might give a small boost or allow higher clocks somehow... more settings is always better

oogie, read what i wrote above, turbo is basically reverse thermal throttling and works through eist... so if you disable it, you cant go up to 21 or 22.

[Mescalamba]

Thanks for tip Pilsy..

.. http://valid.canardpc.com/show_oc.php?id=677592 - I´ve made this before, but now it was much easier - 4415 MHz .. not bad for C0. Also broke my personal SuperPI 1M "record" - 9,344s .. I know, it sux.. but my memory simply won´t work faster.. Definetly need new one..

Yep and made 4.2GHz stable.. and even quite decent temps (for C0 and air cooling).

I think I´m quite happy with P09..

PS: I was quite scared.. 1.63V vCore is much more than I feel good with.. brrh.. not going to do this again.. not on air.

[MagicBox]

Hmm you guys make it too tempting for me to go play with P09 and see what I can achieve over G25 :P

Btw, now QF doesn't seem to be dead, are we finally going to see the QF VFD too? That overclock panel to put in a drive bay. I will be so over that if that gets released

[Mescalamba]

G25 can do a lot.. try it and you´ll see..

VFD? Hah.. I don´t think so.. I don´t even believe in function of QF longer than one month.. But they are free to convince me, that I am wrong..

[PiLsY]

Regards cooling- Ive ignored voltage since p4 prescott days - just keep the temps below 90c in Linx and everything is all good. 90c in Linx gives me 72c max in prime and about 65c gaming.

This particular cpu likes volts and doesnt give off much heat for it. Im using a magicool 360xt rad, parallel flow ek260gtx in sli, chipset and an ek supreme lt all in the same loop. Ive got a 240mm to add too when i can make some brackets and cut the floor out the 5.25" bay pod in my case so may squeeze more out of it then.

No luck with 6x ram multi and by spd settings mescalamba? It sets 6-6-6-14-1t and runs pretty sweet .

I'd agree with your comment as well - it doesnt get you any higher running lower multi and turbo, just makes it easier to achieve.

[Mescalamba]

Nah, those rams simply don´t work lower than CL8.. its some trash Elpida or something worse.. just cheap bad rams.. Funny that there are ram, which cost less and are way better..

[PiLsY]

These Ballistix 1333 C7 are good - very cheap over here, I bought 6gb new for £60. Not sure for you though, but crucial should be pretty reasonable priced across europe I would have thought?

[PiLsY]

I'm measuring vTT as 1.666v off the DMM pad - as people say this is reading too high what would my actual vtt likely be?

Is there anywhere more accurate I can measure it from?

[Mescalamba]

Yea I tought about buying Crucial some time ago.. maybe I´ll.. I bough lots of things in UK (my BR too for example). I think now about CSX D9KPT based rams.. do you know what chips have your Crucials inside? Its Micron, thats sure..

[To(V)bo Co(V)bo]

I got some OCZ OCZ3P1600LV6GK 3x2gb sticks and they are D9KPT really cheap too.
