Aver,
If i recall, you *backflashed* the backup BIOS with an older version, is that right?

Has ANYONE here successfully backflashed the backup BIOS with alt-f12 and NOT bricked their boards? (I don't suggest you try it until you get your RMA'd replacement from the recall...)

I did the following :

Flashed to F7 and set it as my backup bios, then realized no LCC option so I went back to F7e. When I tried to flash F7e over F7 in the backup something happened and it went into infinite boot loop. I have a new board coming Monday so I will be able to tell you if my CPU or Mobo was the culprit.

uf my friend thats very bad news gigabyte has been standing the flag "use our ports" i talked to them so if intels become degraded we are f*kd

They won't degrade like the Intel ones, but they are not going to be very fast is what I meant.

Also terrible for SSD and don't even think about RAID SSD on them.

P67 Intel 6Gb/s ports are what you should use!

[cowie]

yeh mate got to look on the bright side ,can't see it being the motherboard . it tries to post but just loops and nothing on the led panel with the boot codes ,i'll get a cpu to try tomorrow

well did a chip help or what? cus....

thats what mine is doing now and no more then 1.61v real with great load temps
i hope its the board i did not even push the chip yet
i looked around local to just get a cheap one but no 1 has them.
i dont think i can get a replacement from newegg bu i'll try.
sending both back hope they still have a few around to send me.

what a sickener cowie eh

***********WARNING********

well good news bad news got another 2600k , installed and straight away the led boot codes started going c1,29 4d etc so i though thats good so it looks like cpu has expired so put original cpu back and just the boot loop again and the led code panel was blank just a red flickers so swapped cpu out and put the new one in and hey presto all the boot codes coming up again c1,29 etc, so plugged everything back in and all booted up fine so definitely the cpu had expired mine had good load temps but needed a lot of v core but temps were in line and i have run probably 100 3dmarks ok i needed about 1.685 volt on the old to be fully stable at 5373, my symptoms before it expired was i had a few bsod's with failiure to communicate with secondary processor and also just before it would not start again when you ran super pi it wouldn't run at all just came up not responding, as said i have been running 4200 all auto and 5373 for benchies but mine needed a lot of vcore right from the start to bench 5373 but as said i have done 100's of benchies at that vcore and speed all ok, also i had upped systam agent voltage the same day to 1.125 i think so not sure what the absolute cause was but v core rather than heat is my guess

[cowie]

oh so mb ok then?
sounds like the same thing i have glen poor chip
just a cycle of on off and flicker in code leds wtf...

i did not even give it alot of vvt .1.20 dram 1.66 sa was 1.035 vcoree real was 1.58 till last night i pushed 1.60 it did not boot so cmos and i was back to bios.
today ok for 1 hour then whiling fighting the flash to back up bios it went bad.
less then 20 hours benching oc'ed in a weeks time???? and i thuoght the 980's were weak.
well now i can buy another to have a back up.

[sin0822]

Ed Marvell ports aren't THAT bad lol. I have been using them for so long for my C300.

[TheHardCase]

Any idea why after a hour up & running the 2600K L3 Cache Read & Write lose speed?
Just keeps getting slower & slower...

[jackbrennan2008]

I think i got the max i can out of my chip now.

And the SuperPI run,

what are you using to test cache speed???

[Falkentyne]

I definitely second that question.

[TheHardCase]

what are you using to test cache speed???

L3 Read will drop to 40000MB/s & Write 30000MB/s

P67 Intel 6Gb/s ports are what you should use!

maybe is better to buy a sata port card or raid one, in that case what card can perform same as the intel ? to raid ?

[sin0822]

AIDA64 eh, i wouldn't trust every program, but it would very well tests cache speed, although i highly doubt it does so. See if you run superpi if you see the same degradation.

Why there is only 2 LLC levels? Other boards has 5. Is it a hardware limitation for this board or something?

We shall see.... I'll join the Gigabyte P67A-UD7 party soon.

Why there is only 2 LLC levels? Other boards has 5. Is it a hardware limitation for this board or something?

Yes the other boards with multiple levels have digital VRM systems, this has an analogue system. You have three levels, standard, level1, and level2, you have what 2 less levels than the ASUS boards?

Either way Standard is meant to be for normal people or those who want a energy efficient system, level1 is supposed be for mild overclockers who want really low vdroop and vdrop, level2 is supposed to be for extreme ocers who want the most stability in voltage delivery. That is why level2 will never drop voltage under 10mv of what you set it at idle and will increase voltage during load. So what you set is what you get plus more, a lot more actually.

In the past there was no LLC, then we got smarter PWMs(analogue and digital) and now most of them use separate ICs for loadline equation and phases switching. Now we have LLC in multiple levels on the good boards(Gigabyte and ASUS mainly) not every digital vrm board has multiple levels of LLC.

For instance digital PWMs can do all this loadline stuff from inside the PWM is one of the benefits of a digital PWM, the VRM is under software control. With the Rapamge3 extreme and other x58 board with digital PWMs the max we saw was 3 levels of LLC 0%, 50%, and 100%. For X58 GB had almost all their X58A with standard, level1, and level2 in an analogue vrm, this is was pretty damn good because it countered all mainstream ASUS boards with a more complex PWM system. So they were on par in the top Rampage/Maximum VS. UD9/UD7(formula=UD5).

Now that Analogue and digital PWMs are just as precise this kind of ruins of one digital PWMs strong points of being more precise(precision comes from the PWM logic circuit in the case of PWMs software is much more complex than hardware thus is more able to be more precise in theory) because they usually always are(a few mv). Anyways with VRD12 Intel is trying to force everyone to use digital PWMs by the end of 2012, so that is why you see the shift toward a requirement that all PWMs allow a minimum of 5mv voltage increase as well as an extra SVID digital channel. This is pretty damn huge, not many analogue PWMs OR Digital PWMs have this ability, but companies that spearhead this industry(Intersil=analogue) (Chil=Digital) really hit the ball with it, Intersil got its VRD12 certification before Chil did which is impressive as well.

Intel also added in stuff like 4 phases server boards that boast 180amps which is pretty damn hard to do. This new spec demands that the VRM industry basically improve heavily on the analogue(or make it semi digital which it already is) or adopt even better digital. It is pretty impressive what Intel has done. The thing is that analogue and Digital PWMs aren't all that different, right now we have a large mix of analogue and digital signals and both types of PWMs have to use ADC(analogue to digital converter) or DAC(the opposite converter) to change all the signals to what they need. in the past they were almost all analogue in the future they will almost all be digital, its on Intel's time. Digital allows for much smaller VRMs though.



This is VRD12 PWM spec its a damn good read:

thanks for the quick tutorial sin. that was a good read.

sooo good eva im wainting for mine to arrive also

cheers

[dinos22]

nice george

click on link

[Johnny87au]

lol Dinos! U like kahlifa too or just taking the piss ??

[dinos22]

i run it before every 32M SuperPi wazza it goes faster

[Johnny87au]

keeping it gangsta ay dinos lol

[dinos22]

just linked a better video :

Hi folks!

I just assembled my new rig (shown in sig) and I wanted to flash my BIOS from F4 to something newer. Tried F7 in Qflash, invalid BIOS. Tried F7e in Qflash, invalid BIOS. Tried F7e with FlashSPI, invalid BIOS. Tried @BIOS, it crashed after reading the F7e file. Am I overlooking something obvious? How can I flash my BIOS?

Thanks!

[dinos22]

use this app and do it in windows

http://download.gigabyte.us/FileList...gbt_atbios.exe


once you flash it make sure you also copy this new bios to your backup bios by hitting ALT+F12 during PC startup
