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?
Keep FSB Over volt at +.2v and see. I usually haven't needed to go over .2v.

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.
^Indeed, this is a very noted problem. A BIOS fix should be available soon.

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?
If you don't go above 55Cfor Northbridge under Prime95 load it should be OK, but I still recommend you put in a chipset fan.

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
fixed-had to remove external hdd!
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.
For RAM timing etc, use Google to see what they are. I have 3.2Ghx on my E2180. I have worked with the EP35-DS3L and has gotten 3.1Ghz on a E2160.

I'm running my Q6600@3GHz on stock voltages. I have to increase Vcore to get it stable at 3.2GHz
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.
1. Check CPUZ under "Motherboard".
2. Yes, Q-Flash is safe.
3. At least 8hts of Small FFT.
4. You need to do it in the main screen.
5. The BIOS image should be the same as the one in the guide.
Also don't install DES.

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?
NEVER DO BIOS FLASHING THROUGH WINDOWS
Here's what I do:
download the BIOS ROM file to a completely empty flash drive formated in FAT32(it has to be FAT; NTFS won't work). Change the the boot order to the flash drive. save exit and then do Q-Flash.
The pic of the BIOS I have in the guide are the voltages that I am running at on the E2180. What is your VID?

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.
You were lucky. Many people get corrupt flashes when updating through Windows.

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 fsb
ram ratio as 1:1?).
Also do I change the ram timings or just leave them for the time being?
| xanadu wrote : Hello:

You will get the red flashing BIOS message, that's normal and nothing to be concerned with if you know what you are doing. The SPD settings are a little confusing. But yes, if your RAM is rated at 800, then you want the right-most number to read 800 for 1:1. I'd leave the RAM timings alone until you get a stable FSB frequency set.
Ok - guys - I ran an OC. The computer posted at 333*8 = 2.66ghz.
Running small FFTs on P95 at the moment, past self 8k ok.
Core Temp shows - core 0 and core 1 at 43C on a 100% load.
CPU-Z shows the core at 2664 Mhz. Core voltage = 1.296V
Dram freq - 399.6 Mhz; FSB: RAM = 5:6 (this is what I don't understand, I put 2.4 on SPD so the mem freq was 800 800, i.e. 1:1. Now it is 5:6?)
One thing I don't get is that when I go to My Computers > Properties > I see 3.33ghz?
Hmmm I don't know. It should be saying 2.66Ghz.
edit: Download RealTemp to monitor temps. CoreTemp is known to be inaccurate.

i have the ep35 ds3l, e7200, and ddr2 800mhz buffalo ram. now, i installed des and i can't seem to change any of my voltages :S. Is there a way to get rid of it so i can change the voltages?
Ok bumped up multiplier to 9*333 - using realtemps now to monitor temp.
Shows minimum 19C max 21C without load.
Distance to Tjmax = 66C
Is that ok?
Ran 3d marks 06. 11495 just 500 marks behind e8400 rigs.
I can feel the performance improvements in games. Like HL2ep2, really smooth but gets a little choppy at a few sequences for a second or three.
Is that because of game coding?
I have my 8800gt oc-ed too.
Just wondering, would a HD4850 b faster?
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.

Please elaborate 'absolutely need the power'.
"'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.

I have a P35-DS3L and a E2200 processor. I am trying to get to 3.2 stable which I would think should be easy because I have read where many have gotten a E2180 to 3.2. Below is an image of my Bios settings. I am able to boot and run Orthos with temps around 45C but I get errors after a couple minutes. Any recommendations? Also can someone educate me a little on core voltage. Intel's data sheet for the E2200 says the VID voltage range is 1.16-1.312. Is this the core voltage? If so, why does the bios say the normal core voltage is 1.325 and most people run higher than that? Thanks for the help.
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.

Yes I have been running Core Temp to keep an eye on temperatures. I see that VID does match my bios. However, this is above what Intel says is the VID Voltage Range is. So I am confused.
Also, how do I know what the maximum core voltage for my processor is?
Thanks again for the help and have a safe trip back.
Jim
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.

My OC (e2180 and ep35 ds3l) is stable @ 3 ghz for 2 weeks now. Should i try to push it a little further on stock?
Will it even post on stock voltage if I raised FSB? (currently - 333*9).
Thanks.
^ 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.

Thanks. This guide has helped me, but I need a nit more help to push my Q6700 more. I get it to reach 3.2Ghz stable after, 8 hours of prime95, not passing 48C in Coretemp.
The settings for this overclock are:
3.2Ghz (320*10)
System Memory Multiplier=Auto
DRAM timing=Auto
DDR2 OverVolt=Normal
Core Voltage=1.2937(I can probably lower it)
Hardware:
Q6700
EP35-DS3L
4Gb Corsair xms2 800 4-4-4-12
I am unable to raise it past 3.2 Ghz. Either it wont post or it Blue screens when windows is starting. I figured that going past 3.2 would require me to optimize my RAM. However, I am not quite sure what to do.
When i set it to 4-4-4-12 it Blue Screens right before the windows desktop should appear. I set the DDR2 Overvolt to +.3V to achieve the 2.1V for which my memory is rated, but speedfan shows that my ram is still at 1.8V. Why is this? What else can I use to check my RAM info? CPUZ doesnt show the voltage.
CPUZ and SpeedFan both show that my ram is running in single channel mode. How do I get it to run in dual channel mode?
Any help would be greatly appreciated. If you need any other information, ask for it and I will provide it to the best of my limited knowledge.

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?

First set the "System Memory Multiplier" to 2. Check RAM voltage under "PC Health Status" in the BIOS. To run the RAM in dual Channel install the RAM in the same color socket (ie black and black or blue and blue). See page 16 in the manual for more info on Dual Channel.

| xanadu wrote : I ran P95 for 6 hrs +. All tests checked out ok.

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

Ok, I am facing a problem.
Though my e2180 on ep35-ds3l oc-ed to 3ghz on stock voltages, since the past 2 days, everytime I boot the system, the psu revvs up halts and revvs up again. In windows, realtemp says the clock is 1800 Mhz.
The system cannot boot with the 333*9 settings?
But it did for over 2 weeks. And passed small tets for abt 8 hrs!
Any suggestions? My psu is Corsair 450vx.
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...

Thanks shadow. I did this and I am now able to boot up at 333*10. After less than 5 minute of prime95 though I blue screen. Prime95 doesnt report any errors though.
I tried raising the VID and that didnt work. I raised the fsb overvoltage to +.1V and that didnt fix it. Should i raise the FSB overvoltage? Do you think I should change the tRD value? I have the F4 bios.

You should be able to use this guide. BUT DO NOT OC through Windows. You will need to increase RAM voltage by +.3

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?
| Shadow703793 wrote : ^Try FSB over voltage. |
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?
