GUIDE: Overclocking On EP/P35-DS3L v1.3.1 [UPDATED: 10/2/2008] - Page 3

Last message on previous page:

Yes, here it is: http://global.msi.com.tw/index.php [...] tech_p35_1

I figured if MSI said it was okay up to 120MHz, why not? Seems like when I did it, there was hardly any improvements. If could differ for others, however.

That MSI page confuses me. How could "fine tuning" the PCIe bus help overclocking (unless we're talking about a 9600GT)?

Hello all!

Do any of you have a link to something that explains the memory straps? I have just built a new computer using the following component but I do not think that my ram is running at the speed it is made for. Here are my componenets:

Gigabyte GA-P35-DS3L
Coolermaster RP-550-PCAR
Intel C2Duo E6750
Kingston HyperX 4x1gb DDR2 1066 (PC28500)
Vista Home Premium 64bit.

Homerdog,

Thank you. Worked like a charm. Do any of you have experience with overclocking on the stock Intel CPU cooler? I was wondering if anyone has done research on this with this processor and mobo.

I am testing right now with memtest on 5-5-5-15 2t at 1066 at 2.2v and have no issues. I will test it tonight with prime95 overnight.

Thanks.

Great guide, love the screen shots: answered every question I had. My new e2160 is at 3.3ghz with vcore set in bios at 1.40v, did 5 hours of Prime without a problem. Must upgrade the bios though, thanks for the heads up.

The vcore needs become exponentially voracious after 3.3 ghz. My plan is to bring it back to 3.2 and see how low the voltage will go, temps are not a problem - arctic 7 is holding it down like a fat kid on a see-saw - but as others have remarked there's no point in wasting electricity for the tiny performance premium after a certain point on this chip.

While this is a great guide, it's too specific. This whole thread is for one single motherboard, which not everybody has, thus it will be difficult to get it sticked. Trying to generalize it will overlap with the OCing guide, so that won't work.

What you can do is gather a collection of specific OCing guides for many different popular motherboards, then it would be excellent.

@ Shadow, a little update to add would be about setting the tRD value. In order to have the static TRead value I believe you have to have the F8a BIOS. I had hard time finding it because of my F5 BIOS, which I upgraded to F8a. It could be a little side note in paren's for those outdated BIOS people like myself

Cool. Ill see if I can get ones for the P5K,etc.

Interesting info about the Northbridge cooler, I do remember a thread saying it was an important issue on this MB if OCing but I forgot all about it when buying for my build. Some recommended junking the stock cooler and replacing it with an aftermarket cooler.

I think I'll stick a Scythe Mini Kaze 40mm Fan on it, see what happens. Shadow how is your NB fan set up?

And is the stock NB cooler attached with anchor clips or mounting holes?

F6 Bios shows the tRD value under the advanced bios memory timings.

"Static tRead Value" to be exact. I checked this and changed it to 8 today.

So you don't need F8 Bios.

Will try to get it to 3.5ghz now...

If thats the case then it should be worded something along the lines of "You must have BIOS F6 or greater to view this option." Good stuff. Then again I must have been unlucky and and I received an old Rev1 board that shipped with the F5 BIOS. That was back in October. I wonder if theres a OC difference between the Rev1 and Rev2 board, I wonder what difference is at all actually.

I doubt there are major BIOS differences, but the only difference between the 2 versions is the USB. The rev2 has 6 on board USBs.

I'm currently running my E2160 @ 3.0GHz, 333x9 Prime Stable after 10 Hours, Temps below 58C.

My Mem multi (SPD) is 2.4, My Mem Freq. (MHz) is 800 on DDR 800 Kingston Hyper X

My Mem timings are 5,5,5,15 and my Static tRead Value is set to 8

DDR2 OverVoltage is (+0.2V), (G)MCH OverVoltage is (+0.1V)

CPU Voltage is 1.3875V

I can run all Prime torture tests for >8 Hours, but if I drop my timings to 4,4,4,12 I can NOT run Prime's Blend Test for more than 20 minutes without losing a core. I could say screw the blend test but I'm running Vista Ultimate so I'd rather not.

1. Any suggestions on how to get the 44412?

..........OR. I can run @ 3.15GHz 350x9, Temps below 65C, Mem multi (SPD) at 2.0 or 1:1, Mem Freq. (MHz) 700

Mem timings 5,5,5,15, Static tRead 8

CPU Voltage at 1.45V

2. I can run my on Benchmarks and I will after/if I can get the first options timing down to 44412. But if you have an opinion about the two scenarios, let me know.

Thanks all, and BTW, great guide.

^ Excellent link, I love the guide, keep it coming!

I'll check out the new BIOS when I get back to the PC next week.

Here you go:
http://hcidesign.com/memtest/
Never tried it my self, so don't know how good it is.

^To make the boot disc you need to burn the ISO using DeepBurner (Burn ISO option) or some thing smiler. Just burning the CD will not work.

Yeah, no trouble really.

MemTest86+ success, no errors. @ 4,4,4,12 800MHz

1. Should I let it run more than once?

See above.

Blend test won't run more than an hour at my current settings.

I checked RAM temps during the MemTest86+ so I'll go ahead and increase the DDR OverVoltage to +0.3.

It's just RAM ....right?

Thanks for the words...errr word of encouragement.

I'm totally stable @ 3.0GHz, 4,4,4,12, 5:6 @ 800 MHz. I think this is my sweet spot. I can run 3.2GHz with a 1.48V but I haven't run Prime yet. Maybe next week.

I tried to post @ 3.4GHz with my voltages from 1.5 to 1.55 and it wouldn't go so I backed off. The only reason I would need to run that hot would be to score over 12000 on 3DMark06, I'm close.

I really don't see this guide getting a sticky unless it's in the MB section maybe. idk. It worked for me so props. As long as we keep posting in it it will stay near the top of this page.

Cheers. Have a good weekend.

~60 @ full small Prime load after 6-8 hours. I'm very happy with it. I don't think temps are holding me back from 3.4

I just don't want to run near 1.6V to do it. Maybe for one 3DMark run.

Well something funny just happend to me. I fried my motherboard!
Was following this guide and another, changed the values showed here. The only thing with voltage i changed was the DDR2, which I increased to +0.4 (1.8 + 0.4 = 2.2...my rated ram volatage) and then also the cpu voltage control, which I moved up one spot from standard. The rest I just changed the values of enabled/disabled as specified.
I saved the changes, computer booted up, went back into bios, check the settings to confirm, then went back to main bios menu. I then pressed Ctrl + F1, and all hell broke loose. Sparks and a small flame errupted from my motherboard that quickly disapeared. I turned off my power and took a look. Seems that behind the back panal and after the cpu, near some 12v capacitor looking things, some little squares marked 50n024 got fried. Only one of them. I took everything apart and will probably RMA it tomorrow and pick up another for $90. Looking at it now I just kind of laugh. Anyone think they know the reason for this? I know I'm alittle vague, but I'm still alittle confused as to what happend. I havn't tried to boot it up again, since I dont want to destroy any other parts.

I have a Corsair HX520

Shadow,

Here are two pictures that give you a good look.



and



I'm actually worried that something else is ruined. Like the cpu or video card from this. I won't be able to check until tomorrow when I get another p35. Is there also a program that can check to make sure everything is running 100%? I'm just worried that I'll plug everything in, it'll boot up, but some hardware will be damaged and won't run to it's full potential.

Thanks,

WOW! The MOSFET is pretty much melted. Some serious voltage musthave gone through that thing.

There could be damage, but you never know until you try it out/test it.
