E6300 Ninja 2.8GHz Overlocking Experience *fixed oc temps*

Update

6300 @ 2.8 GHz:
~40C idle with EIST (2.4 GHz), ~60C orthos load (I'm estimating that the fan speeds are 800-1000 now as opposed to 1000-1200+ previously, so load temperature has improved even more than it appears!)
Ambient around 17C

cmthomson's suggestion worked, thank you! I have read the article on your P180/E6600 system, and it is drool-worthy and educational

.

Basically, the default setting for Vcore on the DS3 is "normal." It also has a field that says "normal: 1.325v." However, normal for Gigabyte must mean auto according to cmthomson's description. I have now set the Vcore to 1.325v.

Speedfan and CPU-Z don't agree with one another on what the Vcore actually is set at. Here they are, if anyone is curious.

CPU-Z shows:
idle - 1.050v
TAT single core loaded - 1.296v
TAT both cores loaded - 1.28v

Speedfan:
1.30-1.31v for "Vcore1"
1.97v for "Vcore2" <- not sure what this is

Overall, I'm very happy with the system. Idle noise is low in frequency and intensity, so it's not very intrusive. I only load during games; so, it's not too bad even then.

The VGA cooler is quite loud under load, though...I'll have to figure something out...

Original post:

6300 @ 1.866GHz:
~33C idle with EIST (1.6? not sure GHz), ~60C orthos load

6300 @ 2.8 GHz:
~49C idle with EIST (2.4 GHz), ~77C orthos load

Ambient is around 19C -- Temps recorded by TAT

I originally wanted to go with an E6400 and o/c to at least 3.2 GHz, but after seeing these numbers, would that even be thermally feasible?

Are these temperatures normal? I can still file down the bracket on the Ninja. It barely makes contact with some inductors, as posted by another SPCR member in the gallery forum.

Do overclockers use upgraded fans if they exceed ~3GHz?

Thanks!

Setup:
E6300 week 31 revision B
Ninja Rev B (didn't file the bracket -- slight contact)
Gigabyte 965P-DS3 Rev 1.00 (not speedfan compatible, unless I goofed)
Antec SLK3700AMB Case
Seasonic 330W S12
PNY 7900GS (stock cooler that does not exhaust heat out of the case)
7900.10 Seagate 320GB 3AAE firmware, for those curious
Creative X-fi (listing it as it's a minor heat producer)

TIM:
Ceramique

Intake fan:
120MM Yate Loon -- mobo controlled roughly 200RPM Less than CPU fan

Exhaust fan:
120MM Yate Loon -- Zalman Fanmate -- guessing around 800RPM

Heatsink fan:
120MM Yate Loon -- mobo controlled varies around 1000-1250RPM

Interesting results.

You should be able to drop your temps a bit further if you duct the Ninja to the rear case fan. I would probably leave the fan on the Ninja.

This is what I have... an old chieftec case open on one side.
e6300, 1.35v (rock stable) @ 3262Mhz with EIST active. Cooled by a modded Zalman 7700CU with Papst 120mm fan (26dB @ 12v) running at 5v. Idle temp: 54-55. Full load with Orthos after 20 minutes at 79 degrees which is very hot.
Will replace the 7700CU with the Ninja hopefully today, but atleast tomorrow..

I'll post my results here ASAP. Hopefully I can lower the temps a bit, because at these temps the summer will be troublesome and I would have to lower the overclock.

That's a very nice overclock -- 466 fsb!

What is your ambient temperature? You're getting 79C at that voltage/clock with 5v?

I'm getting 77C at what I believe is 12v, and it's winter here...

In your top post you never mentioned what voltages you are using. But personally just looking at your temps from idle to load, there could be something wrong with the way your seated your ninja. Might want to try reseating the heatsink and making sure the paste spreads evenly.

Also run TAT for at least 10 minutes to see what your max temp is. If TAT makes you throttle back that isn't good (even if TAT is way beyond real use it still means it's possible). And another note when Kaleid talks about his Voltage in his reply, I'm pretty sure that's after vDroop, so he's reading it off CPU-Z or something similiar. Kaleid what's your voltage set to in BIOS?

Here's my setup:
E6400 @ 2.8Ghz v1.3125v BIOS v1.28 CPU-Z
Idle: 41ÂºC Load: 60ÂºC (TAT)
Ninja Rev.B Nexus 120mm @ 600RPM

Bad luck, since it seems the Ninja doesn't properly fit my Gigabyte 965P-S3 motherboard, the heatsink has contact with a plastic component...and on top of that I had bad luck with the mounting system. Seems I broke one of the plastic whatever-it's-called that pierces through the motherboard...but I improvised and used a screw. Worst mounting system I've ever dealt with. But it's mounted now, and temps are the same as with the Zalman...so it really can't have proper connection with the CPU. Fan used is the Nexus 120mm + zalman resistor.
Gonna have to try to return it and switch to something else...

Don't know the ambient temperature, but's rather cold in here atm. During the summer this setup simply won't work, 79 full load is simply too much.

Bought another Kingmax DDRII 800Mhz 1GB RAM module which at default runs at 1.8v (required for many Gigabytes), so it seems I can't run it at 7x466 and had to lower the FSB to atleast 7x450 for stability. Another explanation could be that the NB is much hotter now that there's no fan blowing on it as it did with the Zalman 7700CU simply runs too hot. Certainly it feels very hot...

More info on system:

CPU: e6300 (1.86ghz) @ 3150 mhz
M/B: Gigabyte GP965-S3 (bios: F7)
MEM: 2x1GB Kingmax DDR800 PC6400 (5-5-5-15) Orig: 1.8v Now: 2.1v
GFX: Sapphire x1900xt 256MB @ 653/1602 (Zalman VF900CU @ 5v)
PSU: Seasonic S12 500w
OS: WinXP Pro SP2
Cooling: Scythe Ninja
HD: 2x Seagate 7200.8 250GB (sata1)
Tweaks: Nej
Mods: Nej
vCore: 1.35v (set in bios. CPU-Z says 1.344)
vDimm: +0.3v
vMCH: +0.1v (don't know original V)
vFSB: +0.1v (same as above)

For comparison...

My brothers system with same CPU, RAM and slightly better (atleast on paper) motherboard DS3 runs at 7x400 = 2800Mhz at maximum 60C degrees. He uses a P150 and the case fan runs at lowest speed so it helps. CPU requires higher voltage than 1.35 and is currently set to 1.375. For some reason the system refuses to go over 400fsb. He also has a lower end gfx card, a 7600GT with VF900 modified with a Nexus 92mm set at 5.5v or 7v.
The cooling is an Infinity with Nexus 120 used with a Zalman resistor.

Can't you change the divider to just run the RAM a little slower?

I think that's a problem with the chipset (heat or bios) and the lowest divider only allows 1:2. So if bus-speed is at 400 the RAM has to be able to run at 800mhz. 450 bus speed and RAM at 900Mhz works and I'm fine with that. I just have to deal with the heat a bit better and I'll try to overclock higher once again. Gotta get the Ninja properly attached first...currently waiting if I can get a new "metal assembly kit"... I'll modify it slightly so it will fit better on the motherboard.

The IHS could be concave.

No it's fine...it just it interferes with some components on the motherboard... Someone on this forum had the same problem with the Gigabyte 965p-DS3 so I know how to fix it.

The Infinity works without modification on the Gigabyte 965P-S3 and DS3.

I think you misunderstand me. Do you know what the IHS is?

The problem here, besides forgetting about the warranty, is that the nickel prevented the copper from oxidizing. Now hopefully the thermal compound will stop any air from entering the space.

Yes I did missunderstand you...read it way too fast. I'll check it later but it seemed ok when I first assembled the CPU. Temps are much lower if I remove the overclocks... idle is in the low 40s or sometimes even below...overclock to 2.8ghz and the temps instantly jump up 10 degrees or slightly more.

I have the same problem as this guy had with his Gigabyte and Ninja.
"Notes: I took a big old file and filed away at one side of the Ninja bracket. It took me about 10-15 minutes and it wasn't that difficult at all. "

Be aware that when Vcore is left on "auto", the BIOS boosts it when the FSB is overclocked.

Since power goes up as the square of the voltage, this alone could account for what you are seeing.

Use SpeedFan, CPU-Z or Everest to show the "actual" Vcore (it is lower than the BIOS setting due to droop, and also bounces around quite a bit). I bet you'll see higher readings at higher overclocks.

It almost certainly will, but even if the copper does oxidize, heat will still flow faster than if the IHS isn't flat.

What concerns me in that Legit Review is when they removed the IHS, it looks like the thermal material underneath it is not spread out all that well.

OW! OW! OW! - I ran that PSU calculation for a E6600 system I was considering, it came up 442 watts and my PS is 430 (I OC'd in the calcs, interesting).

Than I substituted an AMD 4200+ X2 also OC'd, and the numbers shot up to 485 watts. This was with the 65W version.

To AMD, never mind.

And I realize that people want to buy expensive ATI type video cards to get more points for folding, but you should see the electrical consumption.
Holy Moley!

Just a little update. I modified the bracket so it fit the Gigabyte 965P-S3 motherboard a lot better, got rid of all the plastics plugs that holds the heatsink and used screws instead for a lot better pressure on the CPU.

Scythe really needs to look into the mounting system, because it's really rather bad in it's originalshape.

The idle temp is now at 45 degrees at idle, running e6300 @ 3150, 1.35v. The CPU surface was not perfecly flat, but I'll take a higher temp and keep the warranty instead.
Havent read out the full load temps just yet, but I doubt it's too high to cool the CPU.

Also changed the NB cooling to a Zalman NB47 that I had left over from previous computers. I'm not sure if it cools better than the original NB cooling or not, but I lapped it before mounting it with once again screws for better pressure. I might change the Zalman with a Noctua once I the economy is in better health once again.
