GUIDE: Overclocking On EP/P35-DS3L v1.3.1 [UPDATED: 10/2/2008] - Page 7

Last message on previous page:
Ok, first of all sorry for not replying for a while. I was out of contry.

@squagel: What is your VID for the E2180?

@cmf_risk: Did you clear CMOS?

Just an FYI that the "System Temp" reported in the BIOS is the South Bridge temperature (not North Bridge). I put a small fan over the North and then the South Bridge. "System Temp" only went down when the fan was over the south bridge.

So in reference to my comments on page 5, I can't really do anything about the South bridge temperature besides better case airflow because my video card prevents me from putting an after-market cooler on the South Bridge. It doesn't help that my video card is blowing hot air on it either.

While the EP35-DS3R isn't quite the same deal, I've had success at 400MHz FSB, with tRD = 7. Memory at 2.1V, 4-4-4-12 1:1. Q9450 @3.2GHz (8x multi).

GMCH +0.2V, FSB overvolt 0.0V. Other settings mostly on auto. No fan on Northbridge heatsink, though I'm contemplating it.

Lupiron has been telling me that the FSB overvolt thing is the FSB VTT which is a voltage on the processor, and thus should be kept quite low on 45nm CPUs, except for higher voltage overclocks. I don't really know if he's right or not... I had the FSB Overvolt set at +0.3V, for a higher overclock, but I don't really want to give my CPU 1.4V. Any insight?

I had a problem where my DS3L wouldn't hold an overclock if you rebooted on purpose (either just pushing the reset button or doing it through windows). I searched the web and there are others that have this problem, but seems only ~10% of the boards have this issue. It wouldn't even hold a 1 MHz overclock.

The solution that worked for me was to save it as a profile in the BIOS before exiting, and when you boot into windows the first time, shut it down completely via windows. I think the issue is that if you don't shut it down at least once, it thinks the overclock wasn't successful and goes back to default. Now I can reboot anytime I want and it holds the overclock.

Just a little FYI for others that might have this problem.

I have Ga-p35ds3l NB 1.25V (MCH), SB 1.05, so the +0.3 gmch is safe or not? will it reduce significantly my chip`s(mobo) life?

Hi everyone,

Specs:

DS3L REV2
Q6600 G0
2sticks of matched DDR2 800 each 1gb
Antec Earthwatts 500
Zalman 9500

Had this board a while and have experienced very temperamental overclocking.sometimes it will easily overclock to 3.2 and sometimes it will not budge over stock speed of 2.4 (and i mean not at all!).took out previous 2 sticks to leave current 2 and that solved the problem but it has returned.i think i have tried everything and it just won't budge one darned bit.

any help very much appreciated,

tom h

Thanks for the guide.
It answered a lot of basic questions a newbie would have. I have an e2180 on a GB ep35-ds3l. Also, I put in a Zalman 9700 LED cooler. The p35s were not available at the moment.

Has any1 had success in oc-ing this chip on this board? Around 3 ghz?

The guide is specific yet I do not understand the concepts pf trd value, SPD, memory frequency. Would anyone help?

Thanks.

got ds3l with q6600 with ddr pc6400 ram.can't seem to get past 3ghz stable

Hello All:

I want to OC my e2180 on a ep35-ds3l. Have dl-ed CPU-Z, speed fan and coretemp. Also prime95. I have a few questions 2 ask:

1> Where do I find the BIOS version? On the GB website, ep35-ds3l only has upto F5 version. Is it advisable 2 upgrade to F5?

2> Use Q-Flash to do it ? There is an option in the MB for Q-flash. Is it safe?

3> How long do I need to run Prime95?

4> Tried doing Ctrl + F1; but did not get additional settings.

5> Can any1 give screenies of BIOS with e2180 + ep35-ds3l?

Thanks.

Thanks.

1) No I meant a BIOS SHOT after a successful OC-ing has been done. The voltage settings would act as a guide.

2) Also, when i did the build, I had installed DES without knowing. But uninstalled it. It has to be disabled frm the MB? Is there an option?

3) will flash BIOS and let u guys know how it went.
OK - TRIED FLASHING THE BIOS THRU Q-FLASH - BUT THE UTILITY ONLY LOOKS FOR A FLOPPY DRIVE AND I HAVE NONE ON THIS BUILD. ANY OTHER WAYS? CAN I NOT DO IT FRM WIN XP?

Ok I got the BIOS flashed to F5.

This is also for others who may be facing similar problems with the ep35-ds3l. The MB CD has a utility called @BIOS that can update BIOS over the net safely.
I used that. The bios is at F5 now. Yay!

The cpu vcore is at 1.32500v for stock speeds of 2ghz. I have kingston 800mhz ddr2 ram and a corsair 450w psu.

Hello:

I wanted to carry out an OC attempt with 333*8. I followed the guide mostly but there was a flashing red message in the BIOS saying - VOLTAGE NOT OPTIMISED. Also add the fact that I was not clear abt the SPD settings I did not go on with the OC.

When I opened SPD - it had settings like 2, 2.4, 4+. When I use 2 the memory freq shows as 800 667. When I used 2.4, the freq shows as 800 800 (does this keep the fsbram ratio as 1:1?).

Also do I change the ram timings or just leave them for the time being?

^Agreed.

Hmmm I don't know. It should be saying 2.66Ghz.

edit: Download RealTemp to monitor temps. CoreTemp is known to be inaccurate.

You need to un-install DES.

The temps are fine. As for Half Life 2, I would guess it's the coding. Yes, the ATI 4850 is faster, but unless you absolutely need the power don't get it as the 8800GT is still fine.

"'absolutely need the power'"= playing at 1600*1200 with every thing at max, playing above that resolution with every thing at max. Playing on a 30" LCD.

VID for each CPU changes. The "Normal CPU Vcore" shown in BIOS is your VID. Boot in to Windows at stock, download RealTemp or CoreTemp and see the VID. It should be the same as the one shown in BIOS. If not the BIOS is displaying something else for the "Normal CPU Vcore". I don't have access to the P35-DS3L as I am in Canada on vacation (Ill be in the US on Sunday) so Ill post more info.

That is interesting indeed. This is the first time I actually noticed CPUs come with a higher VID than that listed on the web. You should post a new thread on this. According the the Intel tech docs the max voltage is 1.5v for 65nm CPUs and 1.45 for 45nm.

^ Please define "stable for 2 weeks" do you mean 2 weeks on Prime95 or some thing else?

You could try pushing more, if it doesn't work remove the battery and start over.

I ran P95 for 6 hrs +. All tests checked out ok.

Have ran games, COD4, Crysis demo, etc. No hangs, crashes, etc. That is stable? Or does stable mean sth else?

Yes. You need a minimum of 6hrs of Prime95(Small FFT). I recommend 8hrs for a high stability.

I have the Gigabyte EP45_DS3L motherboard...the pictures of the bios screens in this thread for the ep35ds3l are almost identical to what I see when playing around with trying to tweak it abiton my P45DS3L board...currently I am using the Easy Tune 6 function to get better performace as I've probably done the bios overclocking the wrong way after reading this thread today...I was unable to reboot but then I had the CIA2 functions still on Turbo and other enhanced features still on instead of setting them to standard as shown in this thread...

Can I follow this guide as my board is also a DS3L model but obviously with a newer chipset...

E8400 @ 3.0 ( 9x333)
ATI 4850
4 x 1 gig Corsair CMX2 (4,4,4,12) mem sticks
650 watt "True Power" supply
500 HD

I'm getting around 12500 in 3d mark 06 scores using the "Easy TUne" oveclocking tool and I'm only getting it to push the system abit with that tool...

^Try FSB over voltage.

Hi Shadow:

I managed to get 3.06 ghz stable with 1.35v.
In order to go to 3.1 or 3.2, should I try raising the cpu voltage and see?

I tried raising the FSB overvoltage to +.2V and I tried changing the (G)MCH to +.2V I keep blue screening right before the desktop comes up.
Anything else I should try?
