i have those on my x38 whats the point of anouncing that its complicated it isnt, and they didt mention pulls for ram

[mrcape]

Bring it on. Namely Foxconn and DFI P45 boards.

[Richard Dower]

This is nothing compared to the new bios options Gigabyte have in store for P45, you think things are complicated now?....lol.

gigabyte has no options on purpose thier market isnt the smartest its mainstream, get a dfi lt/ut then u will have the options and more now, or learn to hex edit on gigabyte bioses

[T_M]

thats the most uninformed post ive seen today, thanks zanzabar....

[MpG]

Yeah my X38's got that stuff too. You need to be a little more careful, but I don't know that it's reaching "complicated" levels yet.

Personally, I find those settings to be pretty forgiving at the lower levels. Once you start pushing limits, they become more important. But by the time you reach that point, I think you SHOULD have to learn thing or two about the equipment you're using. Just like any other hobby/sport/activity, right?

what do u mean, gigabyte isnt marketing to the overclockers, and they set most values that u dont see in the bios without u seeing them

[Richard Dower]

They are now, they've seen the light.

[Fr3ak]

To make it clear: What Richard describes is a problem of all chipsets for Intel mainboards and not just P45.

For most people it is sufficient to let those options set to auto. If you want to squeeze everything out of the system, the mentioned options may give you another few MHz of FSB or memory speed.

[STEvil]

Nothing new and certainly not the most complicated if you've ever played with Socket 939 DFI hardware.

[largon]

I miss DFI S939 bios - mainly for the buttload of RAM timings.
I'm not interested in tweaking RAM on LGA775 boards as there's hardly any fun in tweaking like mere 2 or 3 secondary timings. Secondly, I hate the quirkyness of LGA775 in general. It's sheer draw of luck if my system boots up correctly, like every 2nd boot or so ends up in a black screen and you'll have to powerdown, switch PSU off and restart. Too often it resets a perfectly stable CPU & RAM OC to defaults...
I'm sooo irked by Intel chipsets...

[Tony]

My point in bringing this to the editors was that all Intel chipset boards which end users can run C2D and C2Q have this issue, FSB has serious limits without tweaking it to keep it in line, especially with quad cores.

Those who do not learn how to adjust skew and GTL are not getting the best from their hardware...

What i mean is that you obviously dont know much about Gigabyte in the last year

[Richard Dower]

Gigabyte have made alot of advances in the complexity of their bios options, the "F1" hidden options is much better now for non knowledgeable overclockers then ever before. The hidden options make even more sense now and moreso when P45 based bios come out. Gigabyte are going to be adding tons of new options aimed at serious overclockers in P45 (screen grabs available)...so for the novice the F1 setting is a must. Personally i'm not into complicated bios settings for the sake of it, especially when Gigabyte and others don't explain what these bios options actually do.

So Tony is right on one level, on another level mobo makers must make more of an effort to explain what these bios options are for and do, or at least have documentation that explains it...these complicated bios options more then ever require mobo makers to help users understand more.

[n-sanity]

I lol'd.

If this is "complicated" for someone, they shouldn't be overclocking in the first place .

As an elitist jerk, i say down with the incompetent

[WoZZeR999]

I don't think playing with GTL's is a completely blind art. Once you know what %'s of VTT your chip likes, you can tweak accordingly. Title should read: 'Now everyone can experience the fun (or headache) of a DFI user on the P45'.

i see what you're saying mate
you are right no doubt

actually my current bench setup is doing my head in

i am lucky to have a P965 chipset board which can shoot waaaay past 600MHz FSB on air cooling so i can easily test E8xxx CPUs and know what i should expect

having said that though this chip i have in the benching rig now is a 520-530MHz CPU on most intel boards and on this P965 i can validate as high as 628MHz FSB on air cooling

now on Gigabyte X48T-DQ6 i've come across some interesting findings and they specifically relate to CPU Skew of +200 >> i've been able to get the board to post past 530MHz FSB....in fact i've been able to get the board to post at 580Mhz FSB thanks to this setting HOWEVER.....the skew is throwing off the signal too hard and i cannot actually load windows at any decent FSB and i've even had reduced stability at 530....actually even 520 that's how much the signal is affected

however +200 setting is the only one giving me these results.........i've experiemented with GTL REF but GB have very simple options which may not be enough.....do you think that i need some more GTL tweaking to bring the signal in line and be able to stabilise reasonably high FSB (close to 580) or is it related to volts or something else?

i'd appreciate your insight in this specific example

[kiwi]

Dinos, I highly doubt you will ever see high (600+) fsb on X48(x38). That chipset is great for QX cpus

Hahah. I OCed perfectly without touching GTLs...but I'm sure it wouldn't be the case if I had a quad otoh...or if I wanted better OC/vcore increase. *Shrug* Maybe for my next upgrade I'll look into it.

[WoZZeR999]

For normal limits OC you don't really need to touch the GTL. With correct GTLs you can lower your other voltages, and lower overall system heat. With correct GTL's, you can also hit the upper limits of your chip with 100% stability (for those who like to run a prime marathon and create a space heater at the same time).

[Tony]

you know guys...the issue i see is since the 965 FSB with dual cores has reduced, tRD is able to run tighter on the newer chipsets but at the expense of having to buy CPU's with higher multipliers.

X48 is good around 420 to 480 with a quad with GTL tweaking and maybe Dram skew, after that forget it unless you get a cherry board or CPU..

You would get even higher if you set the board up bang on where it needs to be.


FSB has hit its limit...hence Intel are dropping it soon IMO

[Mav451]

Im gonna agree if you havent seen the DFI bios for s939 and S754 your missing out lol.

Lol I came from an Ultra-D.

Problem is that I bought only half-decent RAM, so I reached the limits too quickly

[Gambit_2K]

This is the main reason my next uppgrade (more of a downgrade really ) will be AMD. VTT, GTL and what not has ruined it for me. Sure it's fun to overclock but it's not that fun to me. I wanna find my max OC in like a 1-2 weeks. Not a 1-2 months. I just don't have the time or patiens.

[Kingcarcas]

My first board was the Ultra-D, that was freakin' insane! I now have a Gigabyte DS3L and an E4500@3.2ghz. I'll take whoever caters to the noobish OCer thank you. Or just copy settings from here whatever.....

+1, i'll spend a few days doing it and that's that, a few more MHZ isn't worth it i don't care about records.
