**Gigabyte GA-X58A-UD7 OC-Tips-Bios-Discussion Thread**

The BCLK-wall dependents on the CPU-batch# and MB (+ RAM too for x10 RAM).
Most current setups are stuck at BCLK222 (with x21 Multi) for 24/7, but this may change with a golden-batch or new 32nm CPUs (or a probable upcoming E0-stepping?) on a new MB, including this one.

I would like to see one these 32nm 6C/12T on this MB. I guess/hope it can do ~@4.83GHZ(230x21) with 24/7 stability. Anybody got the combo?

EDIT:
This was like WOW... Sniper posted a BCLK230 while i was typing this.
EDIT2:
I would like to see it with x21 multi, but i guess you need a 32nm CPU for that.
BCLK230 is great, even with x19, on current CPUs. Good job Sniper

Just about any batch i7 can do past 222BCLK when using sub zero cooling.

The biggest issue getting passed 222BCLK is the mobos. So far, only the Gig UD3R rev. 1.6, the new Gig X58As, EVGA boards,Asus R2E, and maybe one or two more here and there can physically get passed the 222 wall. This is because none of the other boards allow you to change the PCIe without a hardmod.

Ive had a P6T, R2E, UD3R rev 1, and now an EVGA E758. The R2E could only boot at 220BCLK, then I had to use TurboV to get get higher. The EVGA E758 can boot 225+ with 105PCIe.

The biggest point to these new Gigabyte boards is that they come hard-modded so you can adjust the PCIe to get over 222.


It doesnt matter what batch CPU you have, if you have it in a board that cant adjust the PCIe, you will not be able to go over 222BCLK.

[Sam_oslo]

Yeah, but we can't use sub zero for 24/7. I'm going to try my luck on air.

I haven't had a chance to try this MB yet, but after seeing some good results, I have good hunch/hopes about getting pretty good BCLK with this MB (with the same CPU, and the cooling that we deadly poeple use).

[Sniper]

I'm no good at tweaking memory, but testing 12GB on UD7 seems ok.

No tweaking of subtimins, all on Auto and Turbo. 1.64vdim, 1.36vtt:

You missed my point entirely.
Just about any i7 will do over 222BCLK with the right mobo and cooling. Batch has very little to do with it.

Someone with air or water can easily test BCLK by lowering the multi, uping the PCIe and volts. This is an indication of what the board is capable of, then the people who have sub zero can decide if the BCLK goes high enough to get the board.

Running 230BCLK for 24/7 with air is by no means practicle, and never said it was. But for sub zero users, BCLK means a lot, and with the right cooling, can run 21+ multi at 230+.

[Sam_oslo]

I don't get your point, sorry.

[pyn]

I don't get your point, sorry.

all he's saying is that it would be helpful for those of us with sub-zero cooling who are trying to determine whether or not to purchase this board if people who already have this board would try and achieve the highest possible bclk and post the results. the reason for this is when you venture into those higher bclk's heat obviously becomes an issue for those of us on air or water and the higher bclk's with a high multiplier would really only be of value to users with sub-zero cooling...

...or maybe I don't get his point either.

Lucky You. Ive been trying for the bast 18 hours yo get mne to even post with 12gb. When it does post, it show 10 or 8gb. bios f3c. Using 6gb now and i agree this board is super fun. Boots at almost every setting ive tried.

Also here is some ss of the RAID 0 performance on the sata3 controller vs the ICH10R. This is 2 gskill Titan 128gb SSD in RAID 0. For some reason the sata3 array is not performing at all, something wrong there. I get the same rsults on the intel controller that i have on every other board ive tried these SSD's on. something for sure not right with the new controller...

the first test is the new SATA3 6gb Controller , the second test is the Intel.

LOL, oh ... you think so ?.
But he is talking about much more ... as far as i don't get it .. also about "Batch has very little to do with it" and it seams that you didn't get the point with this part either, or do you?

I thought I made it clear that I have air-cooling and looking for 24/7 stability. But higher BCLK is not just for sub zero people. My own CPU runs with less Vcore with x19 multi, and 230x19 would be a much better option than 219x20 for my 24/7 use. I know this is true at least for me (my CPU-batch# got much to do with it). So you see that ability to hit a higher 24/7 BCLK is good option for us deadly people on earth too.

I believe everybody would appreciate to hit higher 24/7 stable BCLK on a MB, because it will always give several options to play with for 24/7 use. It is not something that only you sub zero folk (up there) would appreciate.

[pyn]

hey now, don't lump me in with those fancy sub-zero people... I'm using a Megahalems just like you. sorry, I didn't know that you were achieving a more stable oc with a lower multi and a higher bclk. I was under the impression that most people were getting better oc's with higher multi's and lower bclk's. I haven't had the opportunity to test this out myself for awhile since my ASRock X58 Extreme took a dump on me but, I am anxiously awaiting some more results from people around xs before committing to the ud7.

[sRHunt3r]

Nugz, those results sadden me
I get 400-450 read and 250-300 write now and for the money, I cannot consider downgrading. Hopefully it is a diver issue, until then I'm again on hold waiting for the I9.

I think I am going to go kill zombies to cheer me up.

[aslanwas]

very nice board, hope to get one in the next time

OK, i see

I got a great DFI that I have been really happy with, but it is over 1 year old and it is time to consider another MB. This one looks really promising (at least to me).

As far as i can see from distance (without trying it myself) this is probably the best MB out there today. Maybe that's why some Classy people are getting jumpy, LOL . But I gott'a try it myself to make sure.

[pyn]

since we have somewhat similar setups, hopefully you do get one and have some glowing reviews so I will pull the trigger on this thing. I have a i7 920 D0 3849B018, which (when the ASRock was operational) was an excellent overclocker.

I'm a lil sad to hunter . If i had to choose right now, i'd go back to my classified. I figured i'd give gigabyte a lil time though. Removed 6gb of ram and i'll find my max clocks for air. I'm sure my 12gb issue will be ironed out in the nex few bios updates. If not, RMA and try again.. I havent looked in to the slow read times on that marvell controller yet. Could be just some settings.....maybe?

[sRHunt3r]

Nugzo, have you done all of the SSD tweaks and made sure that the write cache is enabled and that the write cache buffer flush is turned off?

[Jakethesnake011]

Thinking about selling my classified and getting this, I had a UD5 for 2 months and loved it, I got better OC's from my UD5 than I am getting from my classified, well 10Mhz BCLK higher, I do like the UD7 thou with the 333 tech on it now and the 24 phase power. Anyone convert from a classified yet? Any thoughts?

With windows 7 the only thing ive been doing is turning indexing off on c: drive. I thought i read somewhere that with win 7, that was all that was suggested to do. who knows if the author was right though....

[nugzo]

After about a day of 12gb troubles, i pulled 6gb out a few hours ago. Been running flawless with the 6gb installed. Re-installed the other 6gb and now i'm posting and running stable with 12gb again. Lets see how long it'll hold up.

Well that lasted about 10 minutes... bluescreen and rebooted showing 8gb. Now im back to 6gb again completely stable.

Nugz, Here is a link with some Windows 7 tweaks ... most importantly the first post has a link to Win 7 SSD tweaks. They should help, let me know how it goes

[lowfat]

I agree with you crashmax, the cpu is the key to high bclk.

True. But most boards can be a limiting factor. I know my CPU will do 250bclk, but my boards have always causing the limit.

You arent more stable with a higher BCLK, you are more stable because you are using a odd multi (19) instead of even (20). Use 21x and lower BCLK for even more stability. I7s dont like the even multis.

Higher BCLK has no benifit for i7, accept for higher ram speeds (if your ram can keep up). Even then, its almost not helpful because the memory bandwith is so high already, you wont notice the difference. A lot of apps actually are faster with lower speed and tighter timings then higher speed and higher timings.

If you dont want to test for a high BCLK you dont have to. I never asked you specificly, I was asking anyone who wanted to give it a try to.

Im working on a chiller, and if this board can do better then the EVGA E758-A1 that I have BCLK wise, Ill probably get it. Gigabyte boards are already faster clock for clock then EVGA boards, so if they can match the same speeds now, they will take number 1 spot.

[Sam_oslo]

True. But most boards can be a limiting factor. I know my CPU will do 250bclk, but my boards have always causing the limit.

Yes, the Core-stability (and Uncore & IMC too) of CPU-batch# got much to do with how high BCLK you can hit for 24/7 use.
When we are talking about using the same CPU, and same RAM on different MBs (and this is most of us are going to do), then the MB (and BOIS options) will become very important, at least for 24/7 stability on anything over BCLK216.

EDIT:
This BCLK216 for 24/7-stability has been the case until now on the most current MBs (with a wall at BCLK222) . I'm hoping (becouse i see indications is emerging already) that new MBs (including this one) will change this to a higher BCLK which will be spescially useful for 24/7 use of upcoming 32nm CPUs too.

[pyn]

nice work! is that the highest bclk you've been able to achieve? correct me if I'm wrong but, don't you usually frequent ocforums.com? if so, welcome and thanks for sharing your results with us!
