BCLK 235 / PCIe 130 with GIGABYTE MB

[dinos22]

haha sick bclk on water only too jeez

[FtW]

Finally got to try some DICE on my modded ud5 & i7 920. First time using dry ice & I ran out before getting any actual benching done, but I did manage a superpi 1m @ 240 x 21.
What is the max bclk that can be reached on a modded ud5?

Edit: after posting the question I saw that hwbot had done the new revision & found my answer.

[=[PULSAR]=]

12C?! or 54F are you outside benching in the frozen tundra?

[Hondacity]

ok

cpu tweaker shows 252 bclks
cpuz shows 238 blcks
real temp shows 226 blckls...

[PlatoonSgtElias]

Hondacity, dont troll please.

To all others: Yes, the PC was on my balcony while the door was closed and I was comfy in +26c :P Outside was -10c i think.
Must look If I have some pics...
Some:

When it was on the balcony I had 3xVolcano12 fans blowing on chipset, VGA etc..
I think I have no picture when I was benching with the rig at that moment but I will have some newer ones soon cuz I have a 5970 now and tweaking the hell out of Win7 right now

124 BSOD normally is QPI/Vtt, you sure you are pushing it hard enough? High Bclk needs high QPI/Vtt (1.4-1.5+), IOH also helps.

[frag85]

Yes. I'm aware 124 is generally Vtt, and below 220bclk that has always been the case. I have tried 1.2-1.46 Vtt and 1.0-1.44 QPI/PLL. BSOD's come sooner >1.4v QPI. 220x21 is stable with 1.36vcore, and I tried up to 1.45vcore and 1.6-1.9CPU/pll to rule out the CPU cores, although x19 and x20 will remain stable so it could just be the completely stable limit of the CPU itself.

The only instability I have noticed is >211x21 my system will freeze after 12 days, around the same time it did the time before. However, it will pass 48 hrs of Prime small FFT, then 48 of large FFT then 24 of blend+video card stressing. It will hang whether I'm stessing/folding or the system siting idle for those 12 days. I spent from July to October last year trying to figure this out. 210x21 has lasted nearly a whole month of uptime before windows update rebooted it so that seems stable.

At this point I'm convinced that I have hit the limit of my hardware for 24/7 stability. I'll keep my 210x21 and be happy with it. If i can have my system up all week folding, and Saturday night play 6 hours of ArmA 2, and go back to folding for the next week, that is stable to me. If 220x21 didn't run towards at Intel's Tcase limit of 68C while folding I would definitely spend more time figuring out this 12 day freeze issue.

I'll start a new thread if I end up getting better cooling and want to get >220 as stable as 210. But I must say i'm impressed with being able to bech and game at 228, and boot into windows and run limited benching at 231. I really lucked out from what I can tell.

Wow! Super stoked guys!!

Just dropped in this 980X in my UD7, and on first boot I could boot from BIOS with 230 Bclk, on water. I didn't try higher yet because I have been busy.

Pushed to 235.07 within a few seconds, seems like this CPU will be GREAT under Dry Ice, I can't wait to try it out!! I think within the next day or so I could easily get 240 or above, on water, so I think I may be able to get 250+ on Dry ice possibly?

These UD7 boards are super smooth to overclock with, very impressive!!


One good shot in for the night, proves to be very productive! I can't wait to get this under dry ice!!!!

Will push Ghz soon and see how far she can go on water. This is the best chip I have ever had I think, and I was told it was kind of a dud, well for LN2 anyway.

I know More Ghz matter to most people, but I have a thing for high Bclk's so had to play around with that a bit first before anything.

This beats my previous dry ice runs at -68C by a lot, with 3 different CPU's (920, 965, W3520) and my UD4P (Modified) I could only get 238-239 Bclk, with a TON of hard work, time, and dry ice. And this is only on water day one with CPU, so nice!!

Now I just need some 2000Mhz CAS 7 memory and I will be set!


Anyone know the current X58 Gigabyte Bclk record? I see 242 in this thread, not sure if I have seen higher anywhere else or not?

hey guys, sorry to bring up an old thread. but hey I have an old mobo
i have just got 230 bclk with no hardmods with only cpu under h20. http://valid.canardpc.com/show_oc.php?id=1559946
i will push for more. but with this thread I was understanding that the wall was in the 22x range?

I am a novice with this pushing hardware stuff so any tips to push further would be nice. Thanks

can i use the F8x bios with my giga UD5 rev.1 ? install with boot usb?

960@4,8ghz

Awesome man! Best I've got so far is 251.78

Special BIOSes from this thread are not needed, if that is what you meant. Those were just to allow PCIE Freq to be set higher in the BIOS after you do the hard mod, otherwise if you do the mod you can use any BIOS and set the PCIE in windows with SetFSB.

If you still want to use F8x, what board was it meant for and why do you ask if it was meant for your board?

Yes you can install BIOS via bootable USB in DOS if you want.

thanks for your answer I can with my ud5 pci103 without no problems 225x19,18,17.....12 boot in windows and benchs are no problem.
when i use set fsb 228-230 bluscreen,my bios version is F12. new bioses i cant use because i have two systems win7+Mac OSX 10.6.5 64bit

here is my run 225x19 with no mods
