Why did OcUK set up my system like this?

I would imagine the 191x21 allows a lower Uncore frequency and a lower QPI frequency. This then allows a lower QPI voltage.

I believe that Gigabyte boards have been found to like the 191x21 better than the 200x20, and as they are going to be setting up a large number of systems and cannot afford "the odd one or two" not to like the settings, it makes sense for them to go for the safer (more likely to be stable) option.


I read an article that went into the DRAM voltage issue in some depth (can't find it right now though), with the guys going well above the 1.65v guideline and seeing no adverse affects until they were well above the norm. Obviously it might not be good for the longevity of the component, but I imagine OcUK are no where near that far above 1.65v.



As said, you clearly have a reasonable knowledge of overclocking and the settings to be used, so you're bound to take issue with how someone else has done it, rather than your own hard work.

You bought it for the guaranteed clock, that's fair enough and I'm likely to do the same for my next build, so I'm struggling to see the problem?
All the settings work, it's stable and they're certainly not going to melt your components any time soon, if at all.
Obviously they expect you to tweak it to your needs, like changing to raid/ahci if you want, and fan settings are probably included in this. Personally I have them all turned off too. The cpu will shut itself down if it gets too hot before any damage can occur.

You've also gone and overclocked it some more anyway?
If I were OcUK and I was feeling a bit nasty, I'd put a question mark on your warranty at this point.
They state that updating the BIOS will void their overclock warranty, so it might be fair to assume adding your own overclock on top would do the same. :(


@ Phantom Mark, hopefully they won't give out the settings, as this is the whole point of the pre-overclocked bundle, you pay OcUK for the effort of finding out what settings work.


Apologies if the above comes across as a bit abrasive, in a weird mood. :(

Sorry I wasn't aware bios settings were a secret lol, I though you were simply buying components which were garuanteed to clock to X.xghz

The clue's in the name - 'pre-overclocked to', not 'overclockable to' ;)

Besides, you'll always get a better overclock doing the work on your specific components, using someone else's settings even on the same hardware will not necessarily be stable on your hardware.
 
I dont dispute that, but as it seems near impossible to at least find some baseline settings for this board and CPU combination I thought it would be worth asking, OC UK even suggested asking on these very forums, ok for you guys who know how to run this things from zero, people like me are trying to learn from others so they CAN do it themselves...........hopefully I can find a way into the secret handshake club somewhere in the inter-what-not..............
 
I've got a strange issue. They have set things at 191x21 which is fine, but when i set to 200x20, it boots with 200x21 (4.2ghz). I cant seem to get it just to do 200x20. Anyone know what's going on?

Have you got Turbo turned on in the advanced CPU features? This boosts the multi up to x21, so turning this off should let you get just x20.
 
I believe that's only if you update the bios (ie flash it) NOT if you just change settings.

Ive been waiting for the new i7 980x processer to be released before making my order. Are you saying that id be voiding the warranty if i updated the BIOS to the latest firmware? Seems rather annoying having to stay to the same firmware when new firmwares are released to make the board more stable etc.

They can't guarantee the overclock if you flash the bios, that's all. So if you flashed your bios and your bundle no longer hit's 4ghz for example, they wouldnt be able to help.

You misunderstand. If one of us quotes a string of numbers at you, and you enter them into your bios, the odds of it being stable are vanishingly small. You have a baseline to work from, it's the stock settings. Take the relevant things off auto (main two being vcore and qpi, set them to 1.2V instead of working out what the defaults are if you like) and set ram voltage to whatever is written on it. That's your base line. Some people find someone else's settings and modify them, and I'm certain google or the search button will furnish you with a wide variety of settings to try. Others work from stock settings upwards. I do this and recommend you do too, it makes troubleshooting a hell of a lot easier later on.
 
Welcome to the forums

20*200 seems to be preferred by gigabyte boards, 21*191 by Asus. There's not much to call between the two in terms of performance.

QPI to vdimm is a tricky thing to optimise. It's either an optimum ratio or an optimum difference, specific to each combination, but it's hard to know which. I'd have expect a difference of about 0.25 to 0.3V though, so who knows. Rjkoneill is probably the chap to speak to.

20x200 lets me set my RAM to 1600mhz on the dot rather than some random figure in the 15xxs :D

Common. There are sometimes dead spots on every board. Sometimes just increasing the FSB by 3-4 mhz fixes it!
