How many people here have E6400's that don't make 3.2GHz?

[Hulk]

I'm wondering how many don't overclock well.

All C2Ds will hit around 3200+ MHz; i don't know of a single instance where they cannot.

The only question is how much vcore they need for that speed.

 

[keeleysam]

Every C2D I've dealt with has hit at least 3.3-3.4 on the retail heatsink alone.

Considering the vcore, that a very nice result :thumbsup:

Better than both my C2Ds have been.

Would you be willing to put money on that?

People were saying the same about Opterons. I purchased three Opteron 144 chips. Two of them were an easy 2.7GHz+, the third one (tested on same hardware) couldn't even hit 2.4GHz with a bunch of voltage.

There's a guy at some LAN parties I go to who has a C2D, either an E6300 or E6400 on an Asus 975X chipset board. Won't do over about 2.8GHz - which is still very respectable. Now, perhaps there's something else holding him back, but it sure isn't any BIOS settings (a number of us checked) and it isn't from bad choice in components. Of course being at a LAN party we weren't about to start swapping parts into someone else's system to find out what was holding it back.

My preference is to say something more in the lines of, "It's very likely you will get X.XGHz, though not 100% guaranteed," instead of a blanket statement stating, "they all can do that." What will happen eventually is someone will make an angry post here saying, "why can't mine?"

Holy wow that's crazy talk. Swapping out components to find the broken bit or whatever at a LAN is what friends are for!

Nah, everything worked fine, just wouldn't clock any higher. Those particular LANs around Chicago are pretty hardcore. Very little screwing around, file transfers, MMOs or any other such nonsense. Just straight on gaming for hours, followed by the obligatory midnight run to TBK (Taco Burrito King) for sustinance.

I run my E6300 7x400 on my P5W DH. 425 is the max. I'm sure it's the mobo and my crap G.skill PC6400 ZX memory (JUNK!) E6400 should do 3.2GHz.

 

[The-Noid]

Most 975x boards only have a 1066 strap. Max fsb is going to be around 400-425 FSB. It is not the cpu, but the mainboard.

I have a E6400 and i cant OC to 3.5 easily at 1.47 VCORE, Watercooler

QFT...that was a no-brainer when I saw it...

Look at how many E6300's and E6400's on the 965p chipset that dont hit 3.2ghz...most of the respected enthusiast boards like Gigabyte, Asus, Abit, etc are hitting 400fsb easy....


I woudl say 3.2ghz is likely easing with the E6400 simply for the fact that 400fsb is not a stretch for most enthusiast boards out there...however the E6300 with its paltry 7x multi needs 457-458 fsb which becomes a bit more to obtain. often taking people who skimped on memory by getting 667 parts beyond their limits...


I have had 4 C2Ds and one quad core....

They all seem to have a max bottable range of 3.4-3.5ghz...All the C2d's were stable at 3.4ghz with the quad core at 3.3ghz.....MOst all of the C2d's can do 3.2ghz at around 1.35-1.37v. The quad cor eundervolts so much under load I set it to 1.4v and it loads at 1.31-1.32v...


Now I woudl never say all E6400's are gauranteed to 3.2ghz cause there is an occasional dud. An occasional chip that was speed binned accordingly. I mean 3.2ghz is a 1.066ghz higher the stock E6400 and 1.333ghz above E6300....Name me how many AMD chips are doing those type of OCs at even max.

My ZX memory ran fine on my DS3 mobo with my E6600 at 7x466...for 933ddr2 with +.5v...

It also runs fine with E6400 at 8x425 for 850ddr2 with only +.4v and cas 4-4-4-12....

ZX sticks are fine...change to cas 5-5-5-15 timings and you should be able to approach 900ddr2...

i would not pair these sticks with an E6300 in my opinion

 

[Avalon]

Duvie, I did once have a 2800+ Palermo (stock 1.6) that was able to prime at 2.7
But I was very lucky. Getting a 1Ghz+ OC on a Core 2 is relatively easy if you've got good parts and an average or better chip.

 

[BigDH01]

3.2 was cake with my 6400. In fact, I didn't even bother booting up stock more than once just to make sure there was nothing DOA. 1.375v, I should try to lower this now as the chip has been running for a couple of months now.

Just for those that don't know..... All of these OC's must be done with a decent motherboard. Just as a test, I got a $52 motherboard, and I can;t get my 6300 past 2100 ! But I have 2 more @3.4 or better on $125 motherboards. You also need GOOD memory, minimum of GOOD PC 6400 for a 6400, and PC 8000 for a 6300 to hit these speeds.

Indeed. I think the Gigabyte S3 is the minimum requirement for an easy 400FSB+ overclock.

at 60c idle sometimes right? lol that retail junk is...junk

975x mobo with older bios was 100% guaranteed the problem to get that limit. Now you can do 400Mhz+ on the P5W-DH.

This is kinda OFF-TOPIC, but...

I don't know about you, but i have my 6600 C2D running @ 3.0Ghz (333*9) is not a super hi-speed (specially when compared against those 3.6+ Ghz OCed C2D) but, by the time being, i don't need more speed.

The good thing about my overclocking is that I lowered the core voltage to 1.24v (CPUZ reports 1.21-1.23V), but I still got a rock solid 24h+ prime 95 test.

Is this normal? I'm asking this because I've seen people raising the vcore up to 1.4v in order to obtain "only" 200-400mhz more.

Haven't you tried to OC without raising - or even lowering - the VCORE?

Different steppings/weeks perform differently. Early CPUS like week26 need voltage.

My E6300 tops out at 2100Ghz?? Is it a lemon or do I need a new m/b???

New mobo

Then you'd need to buy all new memory and video too

I said this above.... That Asrock board, and any board under $100 that I have seen won't do squat. The S3 is the cheapest motherboard to get a good OC that I know of.

 

[DrKrFfXx]

Yeah, maybe is the stepping and stuff...

I got mine around september, Stepping 6, revision B2.

I was just curious to find out, Thanx.
