GUIDE: Overclocking On EP/P35-DS3L v1.3.1 [UPDATED: 10/2/2008] - Page 5

Last message on previous page:
I reset the NB heatsink and temps are still the same even at stock...48C. Maybe just a bad sensor because the heatsink is cool.

You're sure that it's the NB and not the SB?

Hm... interesting... I have been looking at other forums (Xtream systems,etc) and most people say that they're NB temps for the P35 chipset is about 55C under full load. It looks like I'm running cold and you guys are OK.

Great Guide!!

Started Ocin myself

Ups to shadow!

Nope. The fan was from an old K6 based rig. I can hear my 120mm over any of the other fans.

One note on the "Performance Enhance" setting. This will set all of your memory timings, not just tRead. I'm running "Extreme" right now, because I couldn't find a working set of timings. Using memset I can see the timings set. Once I find the time, I'll see if I can take this baseline and tweak it a little more.

Also, the BIOS version being used will make a difference. For some reason, the F7 BIOS I was using on my P35-DS3L Rev 2 wouldn't give me a stable overclock at 400x8 with my 2160, but the F8b BIOS does.

Also, what is the Static tRead Phase Adjust timing? I'm not sure what it corresponds to in memset, and I don't know what impact it has.

I mentioned the Performance Enhance because the main guide only mentions the Static tRead timing, and might be misleading.

Also, I'm playing with the timings to see what kind of benchmark I can get. I realize I'll never really see a difference, but it's fun.

How did you fry the NB and what program/where in that program do you view the NB temperature?

When overclocked the only thing that works is the feature that lowers your multi. The feature that auto lowers your Vcore doesn't work.

Updated 4/22/2008
Included new note under "CPU Host Frequency" about BIOS versions.

I apologize if I sounded critical, this guide is the reason I have a successful overclock now.

Thank you for your excellent work.

Both options are available but when I OC the cpu only the multi will lower, the voltage stays the same. But when I run the cpu stock both work normally as expected.

Frying my NB is my guess to what happened. I was struggling to stabilize my E2160 @ ~3.3GHz. After a decent Prime ~6 hour small FFT run with temps ~68C I got a BSOD. I'd been working on this all day and I thought I had it. Needless to say I failed the patience test which is probably the most important thing when OCing. So I went from +0.1 MCH to +0.3 without a NB fan.

The next attempted post gave me the No Signal Input or black screen. MB gave me a longer beep then normal and all the fans turned on but that was it. I pulled everything. Reset everything. I had spare GPU and RAM to use so I eliminated everything except the chip and the board, so I sent the board to Gigabyte. They sent me a board a few days ago but they haven't responded to my inquires as to what was wrong with the board. They won't even tell me for sure if it's my board or a refurbished one.

Lesson learned. I guess I'll stick to 3.2GHz. At least I can do it at 400x8 now. Like I said, I couldn't do that with the old bios.

I did tell you that you're gonna kill it.

on my board its gpu i found this out by kicking up fan speed whith ntune and watch temp start dropping riteaway

My punishment fit the crime. Two weeks without my new comp. was hell. I started drinking and smoking again, during that time.

1. I don't know. Sorry

2. Outright crashes when testing with Prime usually indicate that your system isn't very stable...

@Asian PingPong:

1. Depending on CPU 75C or 85C or something else. Also if the motherboard is set to a Temp trip it will do the same.

2. Could be PSU issue.

I had the same issue with the board. No errors, just rebooting. I updated the BIOS to F8b, and that fixed it.

I don't know if it was motherboard, RAM or what, but since the BIOS fix worked, I'm guessing motherboard.

I have to say, it's frustrating not getting an error, just a rebooted machine when you check on it hours later. At least with errors you know what went wrong.

you may be rite im gettin confused im new to this ocing the last rig i built was 8 years agoand that was amd this one is intel ok .
this is what im tryin to figure out before i attempt an overclock
im running speedfan and coretemp side by side
coretemp and speedfan report the same for core0 and core1
27to28c at idle but when im in bios and just let it sit for anhour cpu temp says42 43 c
that confuses me
now speedfan
temp1 56c but when i kick the fan speed up on graphics card temp drops 10c within 1 min.
temp2 34c
temp3 2c i know this is nothing
hdd 30c
core0 same as coretemp 27 28c
core1 same as coretemp 27 28c
core 74c
ambient 57c
if i go into ntune turn vid. card fan speed up to 70 percent temp1 core and ambient drop drasticly within a minute
temp1 47c
core 42c
ambient 32c
sorry about the long post but im afraid to overclock without temps i can trust
my system
ga-p35-ds3l
intel e2200 2.20gz
stealth xstreme 600 w
pqi 2x2 gig
evga 8800gts 512 ko
maxtor 120 gig hd
coolermaster ammo 533 case 2 120mm fans
lg 22 monitor
windows xp 32bit

this is with gpu fan set at 70percent

thanks alot for the help shadow
you think cpu temps look normal thanks again

Thanks for making this guide, it was really helpful!

What method do you suggest to use for attaching a 40mm fan to the NB?

Fantastic guide! One question I do have--I'm planning to try 3.6 GHz on my E8400/DS3L combo after I get my temps calibrated, and to do that, do I just set the CPU Host Frequency to 400 and the Memory Multiplier to 2.00, or the Host Frequency to 200 and the Memory Multiplier to 4.00? You say something in the guide about 800 MHz frontside needing a "200" in that field.

Great post. Thanks Mate

^You should be able to OC the E7200 to 1333FSB. As long as you don't install the DES software DES will not affect the OCing, it is a bad idea to install DES software imo, the energy savings are not worth the possible instability..

PS: I believe this is the legit review link?:

according to that the voltage is ~1.3v, so you may or may not need to raise the voltages.
