My first stable overclock results

peter212693 · 12 Sep 2007 at 21:24

Hi all,

I have my E2160 @ 3.15Ghz with 1.475v in the BIOS and my Ballistix @ 4-4-4-12 840mhz 2.1v. Here is a screeny:

Can you give me some advice with anything else I can do.Depending on the 8 hours Orthos which im confident wit has Ive had 9 hours small FFTs. Im going to try lower the volts to 1.45. Ive tryed for 3.2Ghz but wont even boot.

Thanks

Looks like Speedfan is giving you the wrong results for the core temps as it's not possible to have core temps (Tjunction) lower than the motherboard reported CPU temp (Tcase). With your CPU the delta between motherboard reported CPU temp (55c in Speedfan) and the core temps is ~15c so your core temps are more than likely ~70c which is considered a little warm for a C2D. Try CoreTemp 0.95.4 to see if it reports the correct temps or TAT if it works on your motherboard.

Even with the cores at 70c with 1.475v it shows your cooling is working well as I'd have expected it to be hotter than that.

As for overclocking further it's more than likely you've reached the max overclock for your CPU. My L2 E2160 CPU was the same and it scaled like yours too with increased voltage except I wasn't able to maintain good enough temps to keep it as highly overclocked.

This is what core temp is showing is this more like it :confused:

The board is a P35C DS3R

PS Thats after 10 mins of orthos with 1.45 volts now

Yep that looks more accurate.

I would try lowering your v-core to 1.35 and see if it improves the temps and then run orthos.

I wouldnt be suprised if its the memory holding you back.

Why would ballistics memory be holding him back? That memmory is extremely overclockerble.

:EDIT: just checked he had 4gb, still dont think it would hold him back to much when only running at 3.1ghz with 423 on ram.

I would put the Ballistix on 2.2v just be sure. Once you do that the memory will be fine to ~1000mhz at 4-4-4-12.

I dropped it to 1.4 and it lasted 30 secs in orthos and blue screened

MumboJumbo · 13 Sep 2007 at 21:18

youve tryed upping the northbridge voltage right?

Also put your ram on 2.2v for now untill its been proven that you defnitly cant get your overclock any higher.

peter212693 · 13 Sep 2007 at 21:38

Here are my latest results

Thats 3.15ghz 1.45v, Mem is 4-4-4-12 @840mhz 2.1v and the northbridge is +0.2v

The temps are way out on speedfan, I got core temp working on about 4 hours and the temps were up around 68oc

DavidB · 13 Sep 2007 at 22:47

If i were you id put the memory to 2.2v, after all it is its specced voltage. Then reduce the timings to 3338, and change the memory divider to 2(so the memory and processor run at the same fsb speed), as your not seeing any benefit from having it clocked higher.

Speedfan seems a little odd, unless your really running a fan at 1.3million rpm

Im fairly sure you could get that overclock a little higher.
Maybe try 3.2ghz ? It runs stable on my E2140 on the same board with same memory, so i don't see why you shouldn't be able to match it

Ive tryed for 3.2ghz but it bluescreens after 4 seconds on orthos

What sort of Vcore are you thinking?

DavidB · 14 Sep 2007 at 14:31

well mine ran at about 1.425, but i guess its all very specific to your processor. Maybe just try notching the voltage up a little and see if it lasts longer without excessive heat.

Ive tryed it on 1.525v and still only lasts about 30 seconds

the ballistix is capable of 1333MHz, and the P35 boards arent affected whether there is 2 or 4 sticks of ram in use

Do you think I would be able to run the memory 3-3-3-8 @1050Mhz ?

That would be 3.0 devide on the ram its 2.0 at the moment

MumboJumbo · 14 Sep 2007 at 18:02

No you would not be able to run them at that. Listern to what people are saying to you and put them on 2.2v and try up the cpu a bit.

I have them on 2.2v now and like a said I cant get it stable past this speed even uping the vcore to 1.5 still no good, bluescreens

WJA96 · 14 Sep 2007 at 21:03

Right now, you don't actually know what is holding you back. Try overclocking one component at a time.

Slacken the timings right off (use [AUTO]) with 2.2V ([+0.4]) and run the RAM divider at 2.0 until you are 100% you cannot overclock the CPU any harder. Then start overclocking the RAM.

I think you may be overstating it's capabilities somewhat. Most of the PC5300 and PC6400 stuff seems to do about 900-1000MHz for about 3 months and then die. Only the PC8500 stuff actually lasts at those sorts of speeds. And I've had 24 sticks of PC8500 Ballistix through my hands in the last 4 months and none of it would run at 1333MHz, so I am a bit dubious about your claim, although an 8hr Orthos screenshot with CPUz showing the RAM speed in the same frame would have course convince me otherwise.
