Hi Jaredpace, do you know what your default vCore is when e4300 runs at default 1.8Ghz?

For you to hit 3.2Ghz at only 1.376Ghz, I'd say your default vCore must be below 1.30v. That's a speedy cool running chip.

e2140 overclocked to 2.8ghz m0 stepping with stock voltage.

Although its only 45c to 50c underload or at least thats what coretemp says while running Prime95. To tell you truth, I didn't even push it to 3.0ghz with stock voltage. I was just happy that it got to 2.8 @1.268v and started playing WoW and got a little lazy to tinker it anymore >.> But with my current temperatures, I should probably try to get it to 3.2ghz. I'll get to it when I get to it I guess.

think my default was 1.30 or 1.32

 

[GundamF91]

Jaredpace, if your 1.376v vCore is read from CPUz, then that's after vDroop effect, so your official VID would've been around 1.42v. It seems reasonable that your e4300 should have default VID around 1.30v. That's a pretty cool running piece.

drew726, running at default VID to get to 2.8mhz is a good sign that your chip is at least average in terms of overclocking headroom. After much reading, it seems about half will reach 2.8 or better on default, while the other ones just won't be stable with some extra juice.

I would say that's slightly above the average vCore it takes for E2xxx to hit 3Ghz. Have you tried to see if it'd be Prime95/Orthos stable at lower vCore that this?

Then again, most of the people who do report are avid overclockers who are successful at hitting high OC numbers, while people with lower overclock don't tend to report the numbers which could be majority.

He's very happy 🙂 chip hits aprox 59c under dual prime 95 (still around 26c to tjuction per coretemp) but its 24hr prime blend and large fft stable. I haven't really tried to push it farther as it doesn't really have good enough cooling to go farther.

That's amazing that you were able to hit 3.2 with such a low BIOS vcore setting. I have an E2140 with a VID of something like 1.2675v, and I needed 1.4125v BIOS vcore to avoid the mobo from restarting under load. I could boot and run Prime95 at 1.35, but the mobo reboots spontainously. It could be a strange fault in my GA-P35-DS3R board too.

I was doing some more tests and ended up having to bump some of the chipset & vfsb voltages from auto to one notch over default to get the system 24hr OCCT stable, it seems a bit more stressfull than prime 95, but I too am amazed at how low vcore this thing is stable at. edit: on the plus side the p5k deluxe does have a working voltage damper option so it's eliminating most of my vdrop/vdroop

- Shipped with an all aluminum HS
- Quiet Delta branded fan
- Plan to BSEL mod and volt mod
- Goal is to hit 2.8GHz on a P4M800PRO-M

So I booted the FSB to 375 and kept it at stock 1.2875 voltage. Seems like its pretty stable atm. Its also running pretty cool, a lot has to do with how cold my room is.

That's a nice overclock drew, I think you can safely go for more. 🙂

MattressTester, those are pretty nice overclockers you got there. I think the E2180 can go pretty far with its default 1.3v. If you put it on a board that can change FSB, you should do 3.2 no problem.

1.1v for my new e2160

What in the heck is up with that. I thought that all Intel E4xxx CPUs shipped with a copper-core heatsink. Is your post an indication that they are no longer doing that? That would be a crying shame, the all-aluminum heatsink sucks compared to the copper-core one.

 

[MattressTester]

Yeah, I was disappointed with the HSF that came with the E4500. All aluminum and the fan was junk. I ended up getting an AC7 for the E4300 and moved the copper core HSF to the E4500.

I'd be curious to know if the E4600 ships with the copper core???

Why not check with Intel? Intel says VID Voltage Range: 0.85V ? 1.5V. Okay, guess it just lists possible VIDs, and not shipping ones.

That's pretty serious Vdroop. Were you stressing it with Orthos while at 3.2Ghz? I wonder if that's because your Antec PSU is being pushed pretty hard.

Motherboard. Asus boards are known for it. There's probably a pencil trick to alleviate some of the vdroop.

I am seeing pretty similar results with my e4500 Allendale I just installed (package date 11/16/07) and also a Abit IP35-E (running BIOS Version: 14). I am coming from an e4500 Conroe and this Allendale is AWESOME. It does 400MHz FSB with no problems at all. My Conroe would aways take a dump and not post at that FSB.

With this Allendale I am hitting 3.64 @ 1.4075v, running Prime on both cores and it is solid so far. My Conroe would only do 3.2 stable. I am running the processor with a Thermalright Ultra-90.

Default core voltage 1.2xxx.

At the moment I am running a single DIMM of RAM. Hopefully when I drop the other in when I am done it is still stable.

I'll see what I can squeeze out of this processor by the end of the morning.

I'm confused. How can an E4500 be both a Conroe and an Allendale. What does CPU-Z say about each CPU.

I think that you are just getting the benefits of a newer, better, production batch.

 

[BlueAcolyte]

E4500, stock VCore of 1.325... 🙁

Currently undervolted to 1.25 VCore, tested with Memtest86+, prime 95, and Orthos for half hour each and seems to be stable.

Mobo is GA-p35_DS3L, 2x1GB of ADATA Extreme Edition RAM DDR2-800.

Cooled with Cooler Master HyperTX2

 

[GundamF91]

BlueAcolyte, it's not a given that your E4500 may not do as well as 1.30v ones. Give it a try and I think you should be able to hit 3.0Ghz at 1.32-1.34 vCore easy. You can probably get to 3.3Ghz at 1.45v.

You know, I just thought of something. Perhaps we have the whole "low VID = high overclock" thing exactly BACKWARDS.

Perhaps the chips that have high leakage (poor chips), have a low VID, and chips that have low leakage (good chips), have a higher VID?

From another thread. Could it be true?

 

[Solokron]

You'll have to re-read what I wrote. I never said they were the same processor.

E4400, L2 stepping
Package date 5/7/07; shipped with copper-plug heat sink.
Default VID: 1.325

Overclocking scales beautifully, but starts too high since I want to run higher than I can and keep it <60c...oh well, beggars can't be choosers and overall I'm very happy with it.

At 3.0GHz it starts requiring more Vcore and gets 100MHz out of every .04v. Here's the list

3.0GHz - 1.365v
3.1GHz - 1.405v
3.2GHz - 1.445v
3.33GHz - 1.485v
3.4GHz - 1.525v
3.5GHz - 1.565v

 

[BlueAcolyte]

You guys are right, I hit 2.93GHz using stock voltage (wouldn't boot at first, maybe a 66MHz jump is too big)

stock @1.325
2.2GHz (stock) @ 1.25! (25C idle, 40C load, VDroop to 1.2)
2.42GHz (10%) @1.257
2.66GHz (20%) @1.262
2.93GHz (33%) @1.325

Although that is a pretty big jump for going from 2.66 to 2.93... Ah well, got the graphics card and RAM running at rated specs, doesn't really matter now
