Overclocking (Main Thread)

The Max FSB was sitting right at 500MHz, but I'm really feeling optimistic that I can squeeze out an extra 10 or 15MHz if I just bump up the voltage a bit...

Daniel Nguyen3 said:The FSB wall hits right around 400, and I'd bet anything you'd see better numbers if you were running a higher-end motherboard👍

That's a solid result. On my Gigabyte P35-DS3 paired with an E4500, I'm hitting that same 400MHz limit, which caps me out at 4.4GHz too.😬

Well, you’ve hit that FSB wall on your processor, and you really need the motherboard to be able to push through around 500MHz... That particular wall seems to be a thing with pretty much all the Series 2 and Series 4 chips out there. Most of those older E8400 types can generally breeze past the 500MHz mark, though these newer Core 2 Duo E8400 models can actually climb even higher than 600MHz... provided you're running a high-end board, of course...🙂

That wall is a common headache with all the Series 2 and 4 chips. Most Core 2 Duo E8400 models will breeze past 500MHz, and if you’ve got a solid enough board, those newer E8400s can even crack the 600MHz mark.🙂

I honestly wonder if they actually mean that the wall is an actual Northbridge wall.

The formula for BCLK is pretty straightforward: you take your default multiplier and divide it by your current multiplier, then multiply that whole mess by your FSB.

NB = ( 11 / 6 ) * 400MHz = 733MHz

Well, "Strap" is just the technical term for it, though honestly, it’s probably easier if we just don't even bother bringing up the strap at all... 🙂

The way you refer to the multiplier doesn't actually change much, the real kicker is that 200MHz default FSB... see, the higher the rated FSB is, the higher that max FSB is going to be, and if my memory serves me right, Razer was actually trying to explain that exact point to you...

Here’s the link from the PC forums.

Yeah, I'm already aware—the bottleneck is definitely that 800MHz bus speed.

But if we are looking at the processor itself, why does it require 1.6Vcore just to hit 380 FSB (3.4GHz)? When I push it to 385, I'm seeing 1.63-1.64V, and once I hit 390, there isn't even a fighting chance of getting into Windows.

2.9 GHz - stock at 1.325V
3.2 GHz - 1.45V
3.4 GHz - 1.6V

The Vcore requirements here are honestly absurd, don't you think?
It looks like I've ended up with a dud L2 stepping...

I haven't even been able to run Super Pi at 3.4GHz (using that real-time priority setting) because I had to dial it back down to 2.4GHz, and now it's being stubborn and won't boot back up again. Honestly, it’s starting to fray my nerves!😁

If it won't happen, it won't happen.😍 Word is that even the new Intel Core 2 Duo E4400 and Intel Core 2 Duo E4500 won't push past 3.5 or 3.6GHz. You can crank the voltage up to the moon, but you aren't getting a single extra MHz out of them.

Daniel Nguyen3 said:but if the processor itself is the bottleneck, why on earth does it demand 1.6 Vcore at 380 FSB (3.4GHz), then jump to 1.63-1.64 at 385, and then just flat out refuse to even boot into Windows once I hit 390...

2.9 ghz - stock 1.325v
3.2ghz - 1.45v
3.4ghz - 1.6v

the Vcore requirements are just absolutely insane...
this L2 stepping is total junk......

I can't even get Super Pi to run at 3.4ghz (using that realtime priority setting), because after I dialed everything back down to 2.4ghz, I just don't have the patience to try booting it up again, my nerves are shot...😁

We are talking about reaching the Max FSB clock here, not just standard CPU overclocking. You hunt for that Max FSB by dropping the multiplier to its lowest setting and cranking the FSB until things start breaking. And listen, if you decide to push past 450MHz FSB on a P35 chipset, you're going to have to bump up the FSB voltage along with all the other voltages depending on which motherboard you're running...🙂

Harold Lopez31 said:If it won't go, it won't go.😍 I've heard people say that even the newer Intel Core 2 Duo E4400 and Intel Core 2 Duo E4500 won't break 3.5 or 3.6GHz, no matter how much voltage you feed them, they just hit a wall...

That’s why those seasoned old E6700 chips can hit 3.85GHz at 1.47V (at least, that's how mine behaved on an ASUS P5K64 Extreme paired with a Typhoon)...😁😁

So, I suppose the best move would be to dial back the multiplier; surely hitting 400FSB should be achievable then.

It’s just a minor overclock, though... Click
🙏🙏🙏 , I know I've probably looked at this a thousand times already, but honestly, it still looks absolutely fantastic.

Yogurt, crime scene investigators, centrifuges, animals on the loose... 🤣😂

Spent a little more time messing around with this piece of junk motherboard. At an 11x multiplier, the > hits 266. Tried 10x and managed 270, but 300 is a total no-go. When I set the FSB to 333 at 9x, the BIOS just throttled it down to 278 on its own. Anyway, I'm sticking with 11x at 266.

I grabbed the B3, tipped the bin, and hunted down that resistor. (By the way, if anyone’s looking, it’s right next to the CPU fan connector.) Our little resistor here isn't exactly high-end gear, but it gets the job done. There’s a smaller one sitting right next to it; you actually need to tighten the larger one (which is pretty obvious from the photo).

Grabbed a screwdriver and tightened the smaller one 2-3 times! !!!!!!!!!!!!!!!!!!!!!!!😲😲😲😲😲:e ek:

Everything looks solid—Intel Core 2 Duo E4500 running at default settings. Ran Prime95 and OCCT, and honestly, I've got nothing left to check. Voltage under load was sitting rock steady at 1.008V. It’s insane!😠 I immediately went back to undo whatever nonsense I'd done. The little jerk wiped the resistor clean, so now I'm going to give it a quick scrub with an eraser before tightening the larger one. Also, shout out to that legendary computer desk where you practically have to perform surgery just to plug or unplug anything.👎

Once I actually get it screwed in, the voltages start bouncing between 1.072V and 1.056V while idling, even though the BIOS is set to its default 1.31250V.

Can someone please answer one very simple question for me:
What the hell? (imagine a loud system beep right as you read that)

wiredmarlin5, help me out here.

EDIT: Okay, I just gave it a good scrub with some rubbing alcohol and now the voltages are back to normal—sitting at 1.280V at idle and 1.248V under load.

First off, are you absolutely certain you’ve got the right stylus in your hand? Are you positive that it’s actually the correct motherboard you're working on? And, man, are you sure you're poking around the right spot on the board... and most importantly, are you feeling confident that you actually know the drill here?

If you can say "yes" to all of those—then honestly, just reach out to Razer directly. 😁

Personally, I tend to avoid tinkering unless it's absolutely necessary...😍

wiredmarlin5 said:First off, are you actually sure you've got the right stylus? Are you positive it's the exact same board? Are you even poking the right spot? And finally, do you have any clue what the hell you're doing?

If the answer to all that is "yes"—then give Razer a call. 😁

Personally, I don't mess around with my gear unless I absolutely have to. 😍

The stylus is B3; it’s clearly labeled right there. Even though a stylus is just a stylus (no offense to them), it helps if it's softer, and a B3 is soft enough.
As for Razer, they keep sending me different links—one time it looks like a DS3, the next it's a DS3-R.
But the actual part matches up perfectly; there isn't any other difference. I've compared everything, and it's an exact match.
We can just ignore that last question.😍

Harold Lopez31 said:The pencil is a B3, as clearly stated on the packaging; even though a pencil is just a pencil (no offense intended to any pencils), it's generally better if it's softer, and a B3 provides that softness.
Regarding the Razer part, I'm seeing the same link used for both the DS3 and the DS3-R.
The specifications match up perfectly; there isn't really any other way to look at it. I've compared everything, and it all lines up.
We can just disregard that last question.😍

If you don't mind me asking, what do you do for a living?

😱 🙂 🙂

volt mod; you basically do this to cut down (or completely kill) the vdrop—though some people call it vdroop, which feels a bit backwards to me)

I saw a guy on the Xs forums who pushed an E8400 past 6GHz—I think he hit 6.2GHz; current wr

Harold Lopez31 said:It's about voltage modulation; the goal is to reduce (or completely eliminate) Vdrop—though some people call it Vdroop, which feels a bit counterintuitive.

Won't that end up frying the motherboard if I run it like that for long periods?
