This e6600 sucks, what am I doing wrong?

[redrol]

Gigabyte DS3 3.3
Enermax Noisetaker 420w ATX 2.0
Corsair 2GB Twin2X XMS 5,5,5,12 1.9v DDR2 800
Core 2 Duo 6600
Thermalright XP90 with Enermax 90mm fan on variable, 80mm delta blower on northbridge

So here is what I have gotten orthos stable so far:

3030mhz 7x433 @ 1.375v
3080mhz 7x440 @ 1.42v
3101mhz 7x443 @ 1.475v
3150mhz 7x450 @ 1.5v


I was using 2.0v on the DDR2 with a 2 ratio, so it basically never got going faster than DDR2 900, and I have tested it before on faster cpu's where it did fine.

What in the hell is going on here? Is this 6600 as bad as it seems? It takes massive amounts of extra voltage for anything above 3030mhz. There has got to be something I am doing wrong. Any ideas?:slapass:

[nicepun]

What video card? Also, do you know what revision your memory is? From what I can gather real quick 1. Your ram may be holding, 2, your PSU may have neough juice to give you a high OC. Also, what temps are you getting at load? These are just a few things to consider.

Stop clocking with high FSB. Get the max multi and then clock it. Right now you don't know what is failing because you are stress testing both your CPU and your chipset.

Gigabyte 7600GT, which worked fine in a ds3/6300 @ 3150mhz 450fsb. Temps are very very low. Orthos load at ~48c for both cores. The PSU is fine. I've measured power draw at the wall and it is only about 200w total according to a killawatt.

The chipset is a c2 965, it should be good for a hell of a lot more than 450mhz FSB. Also it doesn't seem to matter how much voltage I pump into the north bridge, it still doesnt clock higher. I have also tested 333 to about 350mhz and basically got the same results with a 9 multiplier.

[nicepun]

Well then, give your ram more juice and hope for the best, otherwise your ram may be holding you back. Check this list (http://ramlist.ath.cx/ddr2/) , find your mem revision and if your ram chips start with D9xxx then you should be able to raise the vdimm up to about 2.3~2.4 but I sugges you putt a fan over them to keep them cool.

I have tested the ram up to DDR2 900 or 450 mhz fsb. The ram is stable at that speed at default voltage which is 1.9, but I have tried 2.0v as well, makes no difference. Also memtest can loop for hours and passes but orthos will not.

[Leeghoofd]

Yep I would opt first for eg 400FSB and see if the cpu runs well at 8 x 400, run ram at DDR800 speeds, then you can try for 9 x 400. Either way this board undervolts ( a la Asus ) but 1.5 CPU Vcore for 3100mhz is way to much, this should be accomplished on almost stock Vcore.... also I'm not an Giga user what bios are you currently running ?

Also because ya hardware ran fine in another mobo doesn't mean it will on this setup like before....

Proceed one step at a time because messing like this might not give the solution nor reveal the problem....Also in regards of memtest , my Ram ran fine at 1120mhz speeds in memtest (10 loops of test 5), but immediately gave errors in SuperPI and Orthos, if memtest fails don't even bother to install or to boot into the OS, if it passes you are one step further but doesn't necesarrily guarantee a bulletproof overclock....

8x400 has been tested and really needs 1.5v to be stable in orthos, but I only tested for about an hour. Remember I am barely asking anything out of the ram, at 400mhz 2 ratio its running stock. I have tried bios f10 and f11a (this is a rev 3.3 ds3).

It seems like no matter what FSB I am using and whatever multipler, I cannot for the life of me get past about 3100mhz with any sane voltage.

[Leeghoofd]

What program is monitoring ya read out ? is there a known voltage drop on this mobo like with the Asus ones ? Coretemp read out at this voltage ?

Also if you passs the 1066 strap you will get looser latencies and ram bandwith performance will be less than at eg 400mhz FSB, I'm not in favour of High FSB running 24/7 stock , 400mhz is already putting some strain on the memory controller...

Im using CPU-z to check voltages and the gigabyte easytune to set voltages, also the bios. Im running orthos right now for instance at 3030mhz. Core Temp reports 47c for both cores, and VID of 1.3250v. I actually have set 1.4v and cpu-z says 1.344-1.36v

Its not so much that I can't get stable, I can but the CPU starts taking insane amounts of voltage.

Disable EIST. C1E is ok.

Motherboard Intelligent Tweaker control + f1

Go back to 9x for starters.
CPU Host Clock Control: Enabled
Lock PCI Express Frequency 105
CIA2: Disabled

System Voltage Control: Manual
Vdimm is fine @ 2.0 for cas 5, most ppl use 2.1v for 4-4-4-12 with your ram.

DDR OVERVOLTAGE CONTROL +0.3
PCI-E OV CONTROL +0.1
FSB OV CONTROL +0.1
(G)MCH OV CONTROL +0.3

Set Cpu Vcore 1.5 volts for now.

This should get you to 3.4ghz unless you have really high temps on your cpu or a poor "f" phillipines e6600. On my e6600/DS3 with your exact same ram, I get 3.6ghz dual orthos blend stable running 4-4-4-12 2.1vdimm and 1.5325 vcore. But my TTBT VX probably cools a little better too. Start there and then you can tweak on...good luck.

NOTE: every time the system freezes/reboots on you at stock settings (2.4ghz) then you manually have to go back into the bios to reset the multiplier (9x) AND relock the PCI-Express Frequency again(goes back to auto).

I tried these settings and it posts but will not actually boot. Looks like I do have a poor 'f' e6600.:confused:

How was fsb 350? 360? 365? Surely it booted at 350...

Core temp says 58c @ orthos load so far. CPU-z says 1.424v with 1.5v set in bios.

[edit2] Gigabyte Easytune says 1.48v as being set(????)

and fail after 4 minutes, upping volts to 1.5 as per gigabyte easytune (cpu-z says 1.44v now)

and fail, not happening

[LagunaX]

Just go ahead and do 4-4-4-12 vdimm 2.1v. (+0.3 on DDR OV Control).
Increase your MCH to +0.3
You can increase your vcore (1.53-1.55) since your are getting so much Vdroop.
As long as you're not going above 60 deg C, your cpu should be fine.
Try 367 fsb. That'll put you at 3.3ghz.
Your HSF like the Zalman 9500 usually can't get average e6600's above 3.3ghz. Just can't cool adequately. However, could be a poor chip too. Definitely doesn't sound like a "b' chip that does 3.6ghz at stock vcore...

remember to relock your PCI-E

[redrol]

MCH on +3 fails orthos even faster, so in about 2 minutes. I can't even get stable at > 3200. Looks like Im going for either 337*9 or 433*7. Both are equally stable except 433 does not resume from s3 correctly whereas 337 does. *shrug*

thanks for the help, I got a bunk 6600

[LagunaX]

If you are running the 1333 strap on the rev 3.3 then you could do the BSEL mod and perhaps get a higher FSB. But if you don't know what you are doing I wouldn't advise it. Ebay it if you are not happy.

[redrol]

Well, I am not happy but I dunno if I care enough. The rev 3.3 does have 1333mhz fsb capable but there is no strap setting that I know of... as far as mods, im not that desperate... yet. lol

Interesting. I just have a feeling that FSB is not my problem in this case. I certainly could be wrong. Hopefully with a little more time I can test this cpu on other motherboards.:toast:

[nicepun]

I have an "F" chip and it's not that bad, it does just as well as the chip you see on my sig that did 4.156Ghz. Were you ever able to take that memory higher than 900Mhz on a different strap?

[NastyDirty]

Gigabyte DS3 3.3
Enermax Noisetaker 420w ATX 2.0

Core 2 Duo 6600
Thermalright XP90 with Enermax 90mm fan on variable, 80mm delta blower on northbridge

So here is what I have gotten orthos stable so far:

3030mhz 7x433 @ 1.375v
3080mhz 7x440 @ 1.42v
3101mhz 7x443 @ 1.475v

If you have a new e6600, then you got a lemon. The new batches suck. You can fool around with the straps, voltages, multi's, etc. Ask for advice, but you will be lucky to acheive 3.4ghz or above. And, to do that, you will have to add a crazy amount of voltage. Intel might be saving the best dies for quad core. Quad core, in my opinion, is completely useless right now. I bought a e6600, and it is a good cpu, but I was expecting alot more. I am disappointed.

[xs64]

I have L30F E6600 and it sucks !! 3.4Ghz with 1.55v stable for max , any higher will become unstable , so be carefull with new batch.

Maybe L630Fxxx are the bad ones.

[dnottis]

Sounds like you just got a crappy chip man.

[rfisher983]

I heard a lot of people are having poor (well compared to other e6600 chips) on overclocking with the newer batch. Where is everyone buying these batches?

Does anyone know if it would be better to purchase a e6420 instead of the e6600 for more overclocking at the end of April ?

[redrol]

Yeah I got a really crappy chip from newegg. This was about 2 weeks ago.:slapass:

[murmel]

I bought my e6600 for about 3 weeks ago. (Sweden)
OC it to 2700 MHz with air cooling.
Then I bought a Asetek Waterchill Xternal water cooling device. Quite "cool"!
Makes the CPU go down to 22 C during idle and ~32 C in full load.
But Orthos gives me some stupid errors everytime i go above 3200 MHz now. My corsair's is doing 4-4-4-10 (2T, 1T and Orthos freaks out, 800MHz).
Is it that the newer versions of e6600 sucks? Or just that I do? :slap:

[soodent]

My L624xxx e6600 is also a canditate for worse cpu in 6600 class.3,32ghz is max
8x416 ,9x360 and 7x455 in different ways.All this on Gigabyte ds3 rev 1.0
Tried rev 3.3 and now 3,15ghz is absolute max.

[johnrr6]

I can get 3.2 stable on my e6600 L632B----that's it....not the greatest...I went as high with vCore as 1.5250 with no luck.....

A lot of people say the 632Bstepping is quite good----mime just doesn't seem to be......

Abit QuadGT

Below settings are rock stable for over 24 hours Orthos as well as any other stress test/3Dmark/PcMark I can throw at it.

Temps on load never went above 45C in uguru----system has no quirkyness and runs smooth.....albeit, at just 3.2

Raise the FSB 2 mghtz----and craziness starts to happen....sometimes little stuff----sometimes major crashes.....

Here's the BIOS settings that seem best:

356 x 9 = 3202
1066 Strap
667 RAM 4:5

Vcore 1.4550 in BIOS (1.42 Load in uguru)

[ineedaname]

I'm just wondering if you're using core temp to measure ur temps or are u using something else?

I've used an XP90C with a 130CFM fan on a e4300 and it didn't cool very well.

[slim142]

I have a L628A and it didnt give me the results I expected.

The highest Im able to achieve with orthos stable for 8 hours is 355mhz at 1.39v, if I go any higher than 355mhz FSB, I will not be stable at any setting no matter what I do.

I just bought another pair of RAM memory to see if its my RAM that is holding me back.

[theteamaqua]

no overclock guarantee....

[slim142]

no overclock guarantee....

I heard there are some E6600 that dont let you OC higher than 400mhz, can that be true?

week 24 e6600 that doesn't do over 3.2 on my p5b dlx

not alone

[cowie]

oh jeez, i just ordered a 66 from newegg to better my 64 3.5. after reading this i think im not gunna see 3.7-8 with it.

[.:\dGh/:.]

It's not motherboard or voltaje issue. Is CPU bad batch.

I have one of the same, y I got 3.88 with 1.65 real, terrible!

[slim142]

The thing is that Im scare, what if I sell my current E6600 and get another one and get the same results :(

Ill just wait, anyways 3.0ghz are good enough for me :)
