X58 overclocking

[Somerandomtechyboi]

Got my hands on a "broken" p6t deluxe, i knew it was most likely just a simple problem like dust in the socket but apparently its even simpler, just the main pcie slot not working prob cause of dust so no need IPA cleaning to boot the thing, and i got it + x5660 for only 18$

 

Ofc ill just instantly mod the bios to rampage iii or p6x58d premium if that doesnt work so no bios crippling bullcrap, but i have no idea how x58 overclocking works and what i should expect on freq

 

Ofc theres bclk, ik i can expect anywhere from 200-230 ish but then theres uclk and qpi link, what can i expect out of those freq wise and how much volt can i push before they start outright dying spontaneously?

 

I also wanna know what cpu differential amplitude is, the bios says it "might enhance bclk overclocking ability", is it just renamed cpu clock overcharging voltage? Cause volt range is similar (700-1000mv) and from my giga ep45 ds4p setting 1000mv clock overcharging volt gives the best ocing results

 

Last question would be whats the diff between IOH and ICH? Cause they both have voltage and pcie voltage, also wanna know how far theyll go before again spontaneously dying

 

Im using spontaneous death volt (aka deathzone) as a reference for actual safe volt cause i would rather not nuke my oc by following an overly conservative safe voltage

 

 

My expectations freq wise is ~4.8 but with enough cooling i bet ill do 5ghz, i have looked at x58 ocing abit and 5g seems to be possible with anywhere from 1.5-1.6v

There is a lot of into to be had about x58 OCing.... its just all very old, but its definitely out there. Just start googling!

 

Its been a very long time since I worried about X58 - I do still have my i7 920 and P6T Deluxe V2 though, ran a 3.82 OC for 4-5 years no issue at under stock voltage, I had a pretty sweet chip, but it wouldn't get to 4 GHz no matter what I tried.

 

I am sure if you can go sub zero you can get 5GHz, I am not sure that is going to happen on anything ambient cooling though, but hopefully I am wrong, I am certainly no X58 expert.

 

Again, just google. All of this info is available. Its going to be hard to have someone give you an entire, comprehensive lesson in X58 OCing in 1 forum reply when there are literally hundreds of other guides trying to do the same thing, and all of them missing some info the others have.

I just copied a 4.62g oc for x5650 off yt and instant boot xD didnt even bother with small freq steps just go straight to 4.6ghz xD

 

Rampage iii bios didnt work so using p6x58d premium bios, forgot to play with rampage ii bios but maybe later, rampage iii bioses got stuck on 0E code

[Somerandomtechyboi]

Me when i get new parts be like:

 

 

Yep, within an hour of getting this board im already aiming to boot 5g xD  i cant seem to get it into the bios cause sata controller isnt initializing, i got it to this point with setting 1.48v (no llc cause thats trash) and setting higher doesnt seem to help

 

Maybe pll volt needs to be increased

 

[Somerandomtechyboi]

 

5ghz boot done, just raised pll to 2v, volt is set at 1.512 no llc, it crashed right after the photo when i attempted to go into ai tweaker menu

 

Lmao 1st hour of getting the board and immedeatly does 5ghz boot xD

 

maybe with a car rad i can make it stable and dailyable at 5-5.2ghz since it only starts getting unsafe once vcore is near 1.7v and 5g only requires ~1.5-1.6v with temps <70c to be stable so dailyable but horrifically inefficient, maybe ill just stick to ~4.6g for daily just to not ruin my parents power bill xD

You are not going to get 5GHz stable for daily use. And I wouldn't recommend using much over 1.4V on a 32nm Westmere for daily use, you will kill the CPU really fast. Around 4.5-4.6GHz is the maximum you can expect for 24/7 stable and safe overclock.

32nm = 45nm when it comes to volt tolerance, intel spec is 1.52v iirc but im fine pushing upto 1.7v daily as long as the damn cooling can keep up (which it cant xD)

 

Basically if i can daily 1.7v on a c2d i can do the same with westmere

 

Intel has mostly borderline volt spec so i think ill follow those so i dont get stuck with a garbage overclock cause of overly conservative safe volts

I dont think my cooler can actually handle that so i think im gonna aim for a rather pitifull 4.4ghz but if i can ill do 4.6-4.8g daily and once i get better cooling 5-5.2g if i really need the extra performance

[Somerandomtechyboi]

Now im trying to clock the balls off everything else

 

Uncore wise it scales with ioh pcie voltage, what is ioh pcie voltage and what volt does it need to spontaneously die?

That's not true. Intel spec for 32nm is 1.4v.

I'd recommend reading some X58 overclocking guides for example this one

1.4 is just getting started, I used that daily for years on my old x5690. My cap was 1.6v for 4800.. winter benching. It didn’t scale after that.

1.6v for daily oc? I've always seen people say around 1.45v would be the maximum safe voltage

No not for daily, that’s why I said winter benching. But I am ok with 1.55 daily.. as long as you can keep it cool it’ll be ok.

Thats more like 22nm spec since that is rated at 1.55v iirc but atleast it isnt a measly 1.4v, thats ryzen voltage, 1.4v was just the standard back then when x58 was still expensive and ppl werent like me and in a matter of an hour after getting the damn thing already booting 5g xD

 

irl its literally the same as c2d volt tolerance wise and thats rated at 1.6v (usually spec is found in the stock voltage range, highest volt in the regular intel specified volt range is usually the rating), though c2d for all i know can daily 1.7v just fine

 

Vcore volt is not a worry at all on these old platforms cause they are just so volt tolerant that you are mostly limited by cooling, heck even a single car rad might not even be enough to really bring out the potential of my x58 bench. P6t are pretty meh but 218 already yeilds 5g so as long as the board is capable of 5g then im not gonna trash on it that much unlike the p6t

That was just when x58 was valueable and ppl were afraid of breaking sht, 1.45v is still capable of ~4.6-4.8 so it isnt too bad but def not as max voltage, more like a realisticly coolable voltage cause good luck cooling a bloody nuclear reactor from 12 years ago

 

My cooler is actually handling x58 pretty well, seems like i top out at 1.4v in terms of cooling capability cause that gets to the mid 80s temp wise and i dont wanna go over 90 since thats inefficient asf and wont get any gain anyways

32nm, 22nm were rated for 1.55 I think. My 3770K did not appreciate 1.525 in the slightest. Literally 1 step away from OVP if you have it enabled

 

It only got me 4900 because it’s a pos.

Well spec is a tad conservative this gen but only by 0.1v, 1.45v is too damn conservative so its fsr better than that

 

Isnt ovp something you can disable with things like elmor evc2? Cause evc2 should have capabilites like disabling protections and even f ing around with volt on the fly so no need for voltmod

 

If i do get a proper bench board that isnt just a low end asus board then maybe ill bother with voltmod just so i can adjust volt on the fly and prob with even finer adjustment than bios

You can do it right in the bios.. should be in the advanced section.. been awhile since I looked at it

 

If you do go with Asus.. reach for the top, that's where the good shit is at.

And any less than their top tier or near top tier boards will pretty much be complete garbage cause gotta love asus bios crippling and lack of settings .-.

 

Tbh i trust giga more than asus at this point just because of how horrifically bad asus bios usually is (lack of settings, bios crippling, etc.)

[freeagent]

I hear you man! I don't buy low end boards, learned my lesson many moons ago. I like their ROG stuff. They used to make good mid range stuff , some of my old  upper mid range 775 boards are still running, just not with me  

 

The oldest board I have now is my old Rampage Formula, a DDR2 board. It did 550fsb daily stable, and was capped at 600fsb because my G.Skill 1066 stuff didn't want to do more than 1200..ah well. I still won my class (air cooled) in Forum Warz with that combo. That year long subscription to the Overclocker that I won lasted like 5 years.. 

 

I did have one Gigabyte board.. X58 UD5. I thought it was ok, but it had bad voltage control, droops everywhere under load. terrible. Looked nice, felt nice, crap bios, shit voltage control. When I got my R3F I never looked back. My buddy still has it running all these years later, so it is Ultra Durable like it said everywhere

Lol if they are still running 12 years later i guess it wasnt false advertising

 

Yea vdroop is pretty horrible but atleast there are llc levels unlike asus where its just llc on or off (p6x58d bios), i do have an ep45 ds4p but that doesnt even have llc at all which i dont really mind since vdroop is ~0.04-0.06v anyways unlike my p5q which vdroops anywhere from 0.04-0.08v

Ive been screwing around with oc and hoping to find a stable oc but no matter what this cpu wont do 4.4g, even at 1.4v, so i think its safe to assume that this cpu is a trash bin, and im stability testing with smallest ffts (already verified stability with same settings but lower clock) so if it fails that then this thing is prob a horrifically bad bin x5660

 

Edit: seems like its not the cpu, noticed that the multi and clocks were fluctuating when testing 4.6g large ffts w 1.42v so i figured the thing is prob thermal throttling, cant verify it not but ill have a look at realtemp/throttlestop for actual temps cause seems like speedfan is reporting inaccurate temps. Guess ill have to get some watercooling on this nuclear reactor
