EDIT: cpu is made in Costa Rica, S-spec=SR0LD, Batch#: 3208C321, S/N: 2V207081A1912. I assume the Malaysian ones are the good ones, knowing my luck. smile.gif

For example, if CPU Strap is set to 125 & multiplier to 38, this will give you 4.75GHz OC. When you set CPU Strap to 125, 125MHz is given to CPU while PCIe/DMI controller get 100MHz. The equation is like this (example):-
BCLK = 125MHz, CPU Strap = 125, PCIe/DMI = 125 / 1.25 = 100MHz
BCLK = 127MHz, CPU Strap = 125, PCIe/DMI = 127 / 1.25 = 101.6MHz

That would be a lot easier to comprehend if I could find a strap setting in my BIOS. smile.gif No mention of that anywhere, same thing with PCIe/DMI. This is my first Gigabyte board, first experience with UFIBIOS, and so far I hate them BOTH! No mention of strap settings, JUST the BCLK, which I can't OC much apparently. Damn thing won't boot with anything other than 100, even with the stock 36x multiplier.

I tried, but only for 5 minutes. smile.gif I set the BCLK to 125 just for giggles. It was much fun watching my PC reboot 5 times before giving up. biggrin.gif I can't find any PCIE clock settings in this BIOS. Christ, this is making me feel like a complete OC noob, at age 42!! If I didn't know better, I'd swear this UEFI bios had NO ability to alter the BCLK / PCIE ratio.

Thanks again for the help guys! I think I might suck up the restocking fee and go back to Asus. I don't like how that company works, but they make nice hardware. Oh joy, another Windows reformat / reinstall / update on the worlds slowest net connection!!

A lot of ppl complained about UD3, its bios settings and especially how the LLC works etc. I was gonna say something when you first posted but dont wanna discourage anyone. AsRock and Asus have made very good X79 Boards. Not that because I'm using an AsRock board but they have built fantastic X79 series and especially the midline boards (extreme3, extreme4) are very competitive in price for what they are giving, especially extreme4. Plus, I got an answer each time I wrote to them in less than 24 hours. Very helpful aftersale department.

PS: I still believe Asus and AsRock are still the same company even tho they announced they split long ago. Characters in their logos are exactly the same and there are a lot of similarities in the parts they use in their boards (especially X79 series).

So, ye, to cut the long story short, it would be a very good idea to send UD3 back, get your money and start hunting for a good X79 board both performance and pricewise.

The stock H100 fans are noisy but they have high static pressure & high air flow. They are good fans. But if it annoying you, you can always swap it with silent fans like Cougar Vortex fans.

Your temps for 4.5 :O is it like 30c ambient there?

Great minds think alike. smile.gif I was at the local nerd store where I bought the board and ran it by them. One of the guys said there was a bios update to show the PCIE options.

Got any recommendations on a solid Asus x79 board? Local nerd store has:

P9X79 PRO - $309
Rampage IV Gene - $279 (it's micro ATX, but sure looks sweet for the price)
Sabertooth - $329

Kinda liking that Gene! I see a lot of guys rocking the sabertooth, but not sure it's worth the extra $50 over the Gene. I know nothing of AsRock, but the Extreme4 looks like a great buy at $229 ($249 with a $20 MIR). Damn, that might be worth a look.

Hey bartman , ive tried 4 different x79 boards ECS DOA bran new FAIL doh.gif Asrock extreme 4 easy board to o/c but 4 me the sata ports dropped out intermittently after 3 weeks very fustrating when port 0 or port 1 does it when u are running raid 0..FAIL mad.gif . Took back got refund bought 1200w silverstone psu with that..Gigabyte up4 nice board no overvolt stupid bios vdroop sozo.gif It works but havent bios updated it so i dont know if issues are sorted out yet...FAIL. wth.gif Asus RF4 now this one died after 3hrs 00 post FAIL axesmiley.png . RMAd that one got it back havent looked back since..does what i want and more. So its your call if it were me RF4 or the R4E so many options to get the results you are after.

Daytime 31 - 34C ambient. It can reached up to 35C though.

Did you see "Processor base clock (Gear ratio)"? That is Strap setting. This X79 OC guide is using Gigabyte as reference:-

There is PCIE options in BIOS but for monitoring/adjusting PCIE clock, there is none. IIRC EVGA motherboard allow user to monitor PCIE clock using EVGA software. If you want to know what clock the PCIE is running at, the only way is to use the calculation in my previous post.

Got any recommendations on a solid Asus x79 board? Local nerd store has:

P9X79 PRO - $309
Rampage IV Gene - $279 (it's micro ATX, but sure looks sweet for the price)
Sabertooth - $329

Kinda liking that Gene! I see a lot of guys rocking the sabertooth, but not sure it's worth the extra $50 over the Gene. I know nothing of AsRock, but the Extreme4 looks like a great buy at $229 ($249 with a $20 MIR). Damn, that might be worth a look.

All three boards you listed are great boards. It all comes down to how much money you are willing to spend. Before i bought this board i narrowed my choices to Rampage iv formula, Sabertooth and Extreme7. They are more or less same price here and purely on the basis of personal reasons, I went with Extreme7. But I know for a fact that my other 2 options were great as well.
So my recommendation would be as follows; (assuming, understandably you dont wanna spend too much on it) Try Asrock Extreme4. Its a great solid board with a very very competitive price. Very good and easy to use BIOS, good onboard cooling etc.Read some reviews on it and watch videos on youtube.I know it will give you everything you want. If you are not satisfied for any reason, send it back and go with Gene.

On the record, I would like to talk about some of my experience with sellers. When you check the customer reviews on certain boards, it is very interesting to find that some people are very happy but some claim that boards don't work properly etc and put the blame on manufacturers. Or, weirdly enough, Seller accuses them on damaging the board which apparently they had nothing to do with. Here is my personal experience that might help potential buyers;

I ordered my board and it arrived smile.gif . Obviously, i didnt know what to expect pacakingwise (afterall we are not experts on how packaging looks like for every board and make). So I fired it up and it seemed ok. Then I watched the unboxing videos that i had watched earlier again and found out strange things about it thinking.gif . For example; There should have been 2 stickers covering DIMM slots but I had only one and it was kinda smaller size( later I figured out that sticker actually is for Extreme9). There should have been protective stickers covering the heatsinks, I had none. Anti-static sponge on top of the box somehow not aligned with the board ( there should have been a cut-out for the right heatsink but there wasn't any) and again found out that part belonged to an Extreme9. Very close inspection showed a tiny TIM residue on one of the capacitors ( i know it didnt belong to me becoz it was silicon based white, mine was MX-4). And i realized that I was not the first owner of this board. Quickly contacted that company and seriously scolded the sales department sozo.gifbruce.gif and told them i was going to Trading Standards. To my surprise they promptly refunded me full even without asking for the board. Later on they very politely asked for the return of the first board "free of postage".
Second time, I went with a lot more reputable company (an international one). Board arrived. But this time I knew what to expect thumb.gif . And again!!!! some weird things, no stickers on DIMM slots at all, plastic protective covering on the socket was upside down, and SB fan was disconnected!!!! I was furious gunner.gifkungfu.gifgunner2.gif as you can imagine. Contacted the guys. not telling here what i said but u can imagine mad.gif Anyhow they asked me to give them a chance to correct the mistake and they sent me another board without asking for the first one. Third time board arrived and this time everything was how they should be thumb.gif
So, I strongly suspect, sellers are trying to push those boards that were sent back by someone else for some reason and they are hoping someone will take it and they will get away with it. Customer reviews also reflect this suspicion. Afterall, which manufacturer would want to send out their produtcs in that order (knowing that they go thru quality control) and get bad reputation?
So, moral of the story, watch as many unboxing videos (especially those made by serious reviewers) as possible and scrutinize every detail of the packaging and the product, so you know what to expect.

Seriously, try Extreme4. If the board you get is NOT one of those "push-around" ones (and make sure it isn't), you will be Extreme(4)ly happy smile.gif
