Already CAS 8, we'll see how tight I can get 'em.
I thought about those, just not sure how much clearance I will have with the NH-D14

I purchased http://www.newegg.com/Product/Produc...82E16820231355 on friday for $135. Im wondering why it has been deactivated? Think it is just so they can sell the newer "made for sandybridge ram? I thought it was a decent price for cl7 2133mhz ram... I guess I will find out when it gets here tomorrow or wednesday...

so for all the other board from MSI and ASUS without Intel's VRD12 does that mean we all lag when it's changing from 1ghz go 5ghz via turbo boost?

"Above you can see the VID change from 1.23 to 1.370 for 3.4 to 4.5 GHz automatically, if this occurs SVID is working properly."


does this work for all boards? or just gigabyte?

Will the Hyper-threading affect the overclockability on this chip? Is there a temp difference between HT on/off?

I like and respect such people like you, that could make some benches in real.

I have a question.
How do you know about PLL, VTT, Dram voltage and other components of motherboard ?
I guess Gigabyte Crew give you such information ?
Am i right ? Or you just Google it ?
No gigabyte doesn't give me info, I tested and I read all the Intel whitepapers, as well as VRD12 PWM spec, and so on and so forth, I find those read points myself and then show gigabyte lol.

Have you had past experience with Asus boards?

I ordered an Evo(need to update sig), but you seem to prefer Gigabyte's alternatives.
Yes I owned a P6X58D-Premium, and 7 years of ASUS boards before that.
I prefer Gigabyte over ASUS on X58 for many reasons, including that their P6X58D-Premium wouldn't take my chip past 215blck, the R3E i bought would do 223 and 215 stable, and then i got my X58A-UD5 and it would do 224 and 215 stable. The Gigabyte boards were just much better built. Plus for sub-zero the R3E and its Digital PWM had a lot of problems with the cold and they didn't upgrade that much for VRD12 and LGA 1155, which isn't good because other companies revamped their VRMs including the PWM. Cold doesn't matter anymore ATM, but will in a few months as Intel releases new chips without cold bugs, or more tolerable cold bugs. Power Delivery is very important, and ASUS is going with marketing instead of quality, Digital PWMs are not very dependable unless they use the best ones, and that is why the EVGA Calssy was such a great board, the Volterra PWM is VERy expensive, and you have to use volterra MOSFETs and even Volterra specific inductors, so its extremely expensive. Volterra is out of the game ATM because they haven't updated their PWMs/design. People have no idea what teh difference between digital and analogue VRM systems are you think 12 phases is 12 phases, but the truth is phases just break down power from 12v-5v to 0.5v-2v, and the PWm controls the voltage levels and the drivers that control the phases, it is the brain of the phase array. While Digital PWMs can be programed, help reduce socket space, are very good at controlling the Loadline equation(different than LLC), they last fast response and dependability. Digital PWMs are supposed to have more precise voltage control, but for SB both Gigabyte's analogue PWM and ASUS digital control down to .5v, both have multiple levels of LLC(Gigabyte uses an off die chip that is a GPIO), right now an Analogue PWM fits best, a Digital PWm will fit very well int eh next few years, as Intel spec starts integrating more digital parts. Analogue PWMs have faster response because everything is hard wired there is no firmware, but the user cannot control the PWM. BUT analogue PWMs are very mature technology, they are extremely smart, the GPIO that Gigabyte uses is an expensive iTE chip that also allows for phase switching. Digital PWMs are much easier to integrate and cheaper, analogue can be very cheap as the case is with MSI(they copy gigabyte so much its not funny, such as with the high quality driver mosfets(drmos), USB On/OFF charge, and a few others things that do not come to mind). MSI advertised DrMOS for so long, but Gigabyte had been using it for years, and the quality of Gigabyte's was recently matched by MSI with their renesass MOSFETs. I just think Gigabyte is doing a lot of things right that ASUS is beginning to lack on because they have gotten to be so damn big, its almost like they put out a product and no matter if it sucks people still like them, its much harder on Gigabyte, and that is why they really strive hard. you have to realize ASUS is worth a few billion and they are the largest mobo company, Gigabyte is second at 100 million.

Great review man. I was on the fence about the UD7 vs the MIV4 and this review really helped out a lot. I am worried about getting a D1 chip over a D2, though. Is there any discernible difference without having to install and check with CPU-Z?

Also, can you link to some of that higher speed ram you were telling someone else to go with? I looked around on newegg and most of the high speed stuff is up in the C9-10 latencies.
And yea no NF200 on the Evo. You cannot buy a D1 stepping chip, as in I am pretty sure you cannot buy an ES chip LOL. yea I would go with nice slow latency DDR3 1866, or some nice DDR3 2000 with decent latencies and downclock it and tighten the timings.

At some benchmarks that do not stress the CPU all the way or to the point that C1E and EIST are not in affect then yes there is a difference, only small though such as when using Superpi on small iterations.

I am pretty sure they all want you to OC with Turbo Boost,but this is fine, the problem is that ASUS wants you to also keep C1E and EIST enabled. If the board has VRD12 certification it will be advertised, but that doesn't mean it doesn't meet most of the specs. So far there are no Digital PWM VRD12 certified because they do not meet all the criteria, I cannot tell you about MSI, but after reading their OC guide I can tell you that they do not require C1E and EIST to be enabled, they actually kept it disabled.

No there wasn't i found that there was no need to turn off HT. If you don't want HT then just get a 2500K.
You can however disable cores, I have seen that work. I did try to turn off HT, and it didn't do anything as far as let me take down vcore or lower temps, none that I saw at least.

im confused with sandy bridge, websites have been saying dont go over 1.5v wih ram, so what you supposed to do with ram that is specified to run at 1.65v and only 1.65?

It's like Sin0822 said, don't worry about it. I don't know where this 1.5v maximum came from, but the UD7 qualified vendor list for memory includes plenty of 1.65v ram:

http://download.gigabyte.us/FileList...a-p67a-ud7.pdf

G.SKILL released their Ripjaws X, which are basically Ripjaws with new heatsinks and marketed for Sandy Bridge. Again, lots of 1.65v kits there too.

yea do not worry wiht it, Intel states 1.5 +/- 3% i covered it inmy guide, i woudl say 95% of people use DDR3 and se 1.65v. I have used upto 1.8-1.9v
