The ULTIMATE Sandy Bridge OC Guide + P67A-UD7 Performance Review - Page 8

post #71 of 710
"
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."


Thank You very much ,very well done..there is a lot of so called "experts" and aSUS fan boys that just talk crap all day long how bad GIGABYTE mobos are for no reason and as for this thread (bookmarked) it could't come in a better time as i was about to upgrade to GA-P67A-UD7 /2600K
Sin0822 you are one of the coolest cat around here ,thanks again

haha No problem, btw you can actually quote someones post by hitting the quote button on the lower right hand side of their post, and then multi quote if you wanna quote more than one persome, with the button right next to that.

I think the UD7 and UD5 are excellent if you want to OC to the max and use it everyday like that. The problem is that you need a board that can sustain very long periods of OC, and gigabyte is excellent in making that happen. The UD4 is also a very nice board. From what I heard its a downgraded UD5, BIOS is different as well in terms of implemented features, its meant to compete against asus p8p series. the UD5 and UD7 are the top of the line Gigabyte boards made to compete with ASUS ROG series.

Hello,

Thanks for putting together this guide.

I read on another guide that the VccSA powers the internal memory controller.

http://www.techreaction.net/2011/01/...idge-v0-1beta/

I just got a new i7 2600k and was reading up on overclocking, and noticed this discrepancy.

Thanks,
Nick

VCCSA is power for system agent, it is tied to memory controller, but it is not the memory controller's voltage. On ASUS boards it is tied more closley to memory voltage. on my Gigabyte board they both come from the uncore power. The IMC(memory controller) is housed in the System Agent. On niether system do you want to increase the SA voltage. There is no point, it might boost your IMC voltage(vtt or VCCIO) by 0.1v, but you shoudl just increase VCCIO/VTT. If anyone tells you to change the SA voltage they are straight up wrong. i knoe what i am talking about.

you shoudl check intels datasheet volume #1. on the first page of my review, that table for voltages is straight from Intel's datasheet.
holy crap i just read that article, idk what board only has System agent and not VCCIO, but if they don't have VCCIO/VTT/qpi/imc voltage(stock is 1.05) then yes you increase SA voltage, but i haven't seen any board like this, not ASUS, not Gigabyte, not MSI, not Intel. What board are you using?

Hey Sin, thanks for the quick reply.

I just got an ASUS P8P67 EVO. In the bios for this board, there are separate VCCSA and VCCIO values that can be adjusted.

When I was reading up on OC'ing sandybridge, I read your guide and the techreaction guide and was a bit confused as to which voltage actually fed the IMC. I guess they both do in a way, but I see your point about the VCCIO voltage being the direct way to increase the juice to the IMC. I haven't tried pushing this board and chip yet (just got 'em), but I'm curious to see how far mine can be pushed.

Thanks again for the guide and the followup.

search for other guides as well, they will all go against what the techreaction guide says about VCCSA, i just think he jumped to quick to publish that guide.

Many people have been reporting that at 4.5ghz they seem to be hitting limits with voltage changing, HERE is what to do.

Use Turbo Mode, your mutlipier will still not drop if you are on GB board, set each mutliplier to what you want, THEN set TDP to 300 and TDC to 300, that is really what helps the extension of TDP and TDC. I edited my guide a litte, i added this tidbit.

no sin i didn't want to do it that way ..people tend to skip,want to make sure some one will read it again

Don't mean to hijack...

I was able to get my $99 UD3 and my $179 i5-2500K up to 4.9GHz on air with ~60C temps.

Thanks for the guide!
