Gigabyte P55-UD3R + i5-660 boot issue

Been running the P55-UD3R with an i5-750 no issues for a month or more at 4.2Ghz, lots of reboots and OCing.

Got a 660 today to mess with under cold water, but whenever I shut down, the only way to get the rig to boot up is if I reset the CMOS.

If I go into the BIOS upon first load and F10 out, it won't boot. Even though I didn't change or save anything.

Tried these BIOS:
F3n
F3m
F4 (latest)

Once I reset the CMOS and boot into Windows it runs just fine (like it did with the 750)

Any ideas? I see quite a few boot issue posts on the internet regarding Gigabyte P55 boards, some have solutions but are nothing related to what is happening for me.

Here be my 660 at stock (boring!) but can't do anything about that :shrug:

Any input? Was planning on upgrading to a UD6 or something (got this board for basically free) but this issue and reading about all the other boot issues, is sort of pushing me toward that Open-Box Maximus III Formula (matches my hardware better too :p:)

Clarkdale, Try this one :)

Thanks! I couldn't find any newer BIOS, and I looked :)

I'm at work but I'll flash it right when I get home and report back.

Works great :up:

You are the KING! Following your 1M action closely too :) (My favorite bench tied with 01)

Flashed the BIOS, booted once at stock, booted 2nd time now at 4.3Ghz looking LinX stable 10 pass already :rofl:

nice...cookie is the man ;)

I Have the same problem... I have a Gigabyte P55-UD5 + Core i5 661 and the OC is very bad.

I got 150 BCLK rock solid with stock QPI/VTT, vcore below defaut (1.165 vs 1.175), but cannot post if the BCLK is above 150 mhz.

I have the latest BIOS on Gigabyte site, F6

Exists any beta BIOS?

P55-UD5 Clarkdale OC BIOS (F7b)
http://rapidshare.com/files/337233062/p55ud5.f7b.html

Still testing, but, the "uncore" option is missing.

seem to be Many P55 BIOS in the market not fully support some DRAM ratio for new 32nm processors

i got some problem with 1:4 , 1:5 with i3-530 + Asus P7P55D

uncore is fused by intel right now, so we didn't open it
also due to MCP（Multi-Chip Package）of clarkdale, which path to CPU
and IGP die is QPI bus. uncore only affects cache.

@hicookie:

Any insight into my issues running 8GB with this chip?

QPI link now affects the bandwidth overall.

The new bios unlock all values of QPI multiplier and got better OC, thanks! :up:

Some fast tests on i5 661 @ 167 bclk, 4330 mhz, ram @ 1670 7-8-7-16-1T on everest:

QPI @ 8.0 (x48)
read: 11825
write: 9327
copy: 11292
latency 64,2 ns
QPI @ 4.0 (x24)
read: 6875
write: 6141
copy: 7377
latency: 81,7 ns

Any of these BIOS recommended for Lynnfield or geared more towards the Clarkedale crew?

Hi, on P55-UD3R with 2*1GB RAM upto 210 FSB working, but with 4*1GB 192 FSB is maxx, even 193FSB can't load BIOS, just restarts with 133 default FSB. But using software OCking upto 200FSB is possible with 4 ram slots. So maybe new bios fixes can be done or some settings in existing bios i missed, hm.

Try use 2T time for high Bclk, due to Clarkdale IMC limitation
My retail 530 is good 240BCLK and 1920MHz CL9 8GB with $20 air cooling

Damn, already took the chip out :p:

With 2T and even 3T at 193FSB can't load BIOS. 192 is fully stable, so very interesting. And I have Lynnfield i5-750.

first time trying P55A-UD3P F5/F6a + Core i5 660 (True 1800 rpms fans)

Guys, especially hicookie :)

I also have an UD3R with an i5 650 and 2x2GB Geil Value 1600MHz 8-8-8-28. My problem is, whatever I set in the BIOS, the CAS latency remains at 10 according to CPUZ, and 11 according to Everest. If I enable XMP the situation gets worse, 10-8-8-28 and the command rate is 2T (despite the sticker in the modules say 1T).

I am running the latest beta BIOS, F5b. Should I try F4 instead?

thanks!

Also, the UD3R review states that we still have to press CTRL+F1 at the BIOS Setup main screen to reveal all the overclocking settings, but I cannot see the difference... What do you think?

UR3R;P55 or P55A?
Latest BIOS is:
GA-P55A-UD3R - F6 and
GA-P55-UD3R - F5
For P55A and P55 series:
-New feature in the BIOS "Spread Spectrum"
(can be activated only in the main menu by pressing Ctrl + F1)

P55-UD3R. On the Gigabyte site I can only see F4 and F5b. Tried F4, but it did not POST as soon as I changed the BCLK...

BIOS F4,F5a,F5b and F5,as previous beta BIOS as well are on the link above or:
http://www.station-drivers.com/page/...a-p55-ud3r.htm

Thanks! I don't know why F5 is not posted on the Gigabyte site...

Well, so far so good - 175MHz BCLK and the CPU is at 4.375GHz with every voltage at auto but Load Line Calibratian is enabled (the CPU is receiving 1.4V at its maximum load, according to CPUZ).

However, the memory situation has not improved - I'm stuck at CL11 whatever I set in the BIOS.

Btw, I had to manually lower my QPI Link Speed to 28x - it would not POST on any higher setting above BCLK of 166 - is that normal? (tried increasing voltages, but no help)

Also :) Is Realtemp accurately monitoring multiplier changes? It seems to change correctly according to CPU load, but CPUZ shows only the VCore changing, while the CPU clock is always at 4375MHz.

a bit OT, u are "gigabyte only Intel" man?:) Or do u have too some good BIOS for AMDs?:)

Using Ctrl+F1, I never saw any extra options in my BIOS either. I have the P55 UD3R.

Also, BIOS F5 seems to be worse for me than F5b. With F5, dynamic overclocking isn't working properly, my CPU couldn't reach the 24x multiplier at all with my usual settings. I flashed back to F5b and all is well.

I hope Gigabyte will improve the BIOS for this board. The Asus boards are much better for overclocking while making full use of power saving features.

For every P55(A) using Ctrl+F1:

Btw,if you always apply usual setting for every BIOS,I don't think so will work for you.Every BIOS it's not the same.

Joining here with the bclk problems with clarkdale :). I`m playing about 2-3 hours and my record for now is 22x191 testing with prime with i3 530 and it froze while I was writing this post after 20mins I guess. Cant pass 193-4 bclk the MB is GB P55M-UD4 is there a clarkdale BIOS? I`m using the F7 BIOS the last one on GB`s site but cant post over 160bclk, these 190 were using ET6.
Thx.

Try with lower multi,18;19;20...and very important is your RAM.

I tried that, no change. Tried even 6x multi for the memory. 22x182 is stable 1 hour prime 95, but I cant boot from BIOS even 170 with the same voltages.

Are you using latest BIOS F7 (or F7c)?
For sure must go over 200.
Have a few good review for your mobo,refer here:

F7 BIOS - release date - 01/28/2010.
Thx for the links man but i cant see clarkdales there. I`m sure there is no problem passing 200fsb with i5 750 or i7.

BIOS F7c-01/18/2010 (F7) already fix OC with Clarkdale more then BCLK160.

Hm does it mean F7c is better than F7? I`ll try this f7c tomorrow to see is there any diffrence.
Well I tried F7c and its the same. Is there a wall on these CPUs or? I can run prime 95 and when i rise the fsb with 1-2MHz it freezes or restarts. Its arround 195fsb from windows. Lowering the multi or HT off didnt help.

Well i solved the problem. Its working fine I booted at 245fsb no problem with low multi. 21x215 prime stable no problem. The problem was PCIe frequency has to be set to auto. I tried to manual set 100, 105, 110MHz it doesnt want to boot. The problem is when set to auto I dont know how high the freq is it can be 120 or 130 lol.

EDIT: LOL Now no problems booting with 100 or 101 manual set wtf.
I guess CPU Clock Drive and PCIe Clock drive made the magic I found that rising to 900mV helps me with the higher FSB.

You can check your PCIe frequency with EasyTune6 or SetFSB (ICS9LPRS918BKL-Gigabyte P55) .
Want to know your reading.

Yeah I checked and ET6 was showing 100 I tested with lower clock and manual set to 103 and it was showing correct, so I guess when left on auto its 100. Dont know what I did but as I said its working now manual set to 100 or 101 also I tried CPU Clock Drive and PCIe Clock drive back to 700mV and it`s also booting :confused:. Tried lowering QPI to 1.35v I was using 1.45 before and still working. Sometimes if I change too many things in BIOS it doesnt want to boot I guess that was the problem. If I change voltages FSB and PCIe it wont boot. If I change and left PCIe to auto and after that I go to BIOS again and set it manually its working. Well I`m playing only 2 days with this board and CPU i`ll find the tricks :).

hey stasio what does that spread spectrum do?

Spread Spectrum in BIOS is set to [Enabled], varies the BCLK (clock) constantly in the range of up to + / - ~ 0.3%. This electromagnetic interference is reduced, for example, be used for the CE regulations. They indeed do not want to cause such interference to radio or television, or possibly also in the connected USB devices that are screened on the cable may be bad. The performance loss is so small that in most BIOSes have hidden the option to [Enabled] . If you want to disable the spread spectrum function, the option is usually only visible when using "Ctrl + F1" in the BIOS menu the extended area is free.

Thanks stasio.

If the only change between F5B and F5 is the addition of Spread Spectrum, surely the same settings (I have them written down and enter them all manually) would work?
