Anybody having cheaper gigabyte mobos besides the P35-DQ6? Like P35-DS3 or P35-DS3R?

What's the average overclocking ability of this mobo (fsb), especially the DS3? I'm planning to get this mobo together with the E6750......

Not much review on DS3 although some reviews on DS3R showed that this mobo can go up to 500Mhz on FSB.....

DS3's heatsinks is nothing compared to DQ6. I do hope that the DS3 can be a good overclocker too. I know DQ6 rocks but so is the price

As for cooling, I'm going for the xigmatek S1283!!!

It's running at 400Mhz quad-pumped = 1600Mhz. I don't have an Intel rig (YET!) but I think that's what it means.....

100% OC meaning your FSB is at 400 Mhz right? Or did you lower the multiplier?

BTW, how high can the FSB go on your DS3? Really interested to know.....

If I get the E6750, 400Mhz only means that I can OC 8x400=3.2 Ghz only!

I want to go higher! Of course, hopefully my proc can go higher.......

I know what he meant. 100% meaning from 1.8 Ghz to 3.6 Ghz. If he used 9x multiplier, that means he would have to increase the bus speed from 200Mhz to 400Mhz, wouldn't he?

I think the 2nd option is better as I just acquired the same configuration - GA-P35-DS3 + E6750.

I did much research on gigabyte mobos and found that the GA-P35-DS3 was suitable for me. Single PCI-E x16, ultradurable 2 features and no raid. Not much review on this board but I think it is equivalent to the GA-P35-DS3R mobo (which is only different by having the ICH9R chipset which includes the raid function). In terms of OC, this mobo is supposed to be able to go up to 490-500Mhz bus speed)

So far, I've tried a bus speed of 420Mhz and it worked flawlessly (at stock MCH/FSB voltages).

For the E6750, the only problem compared to the E6850 is the 8x multiplier. If you want to aim for 4Ghz (dunno whether possible or not), you would need a bus speed of 500Mhz!!!

So far, I'm orthosing my E6750 at 1.35v (stock voltage) at 3280Mhz. That's the highest stable OC I can get on stock voltage. Probably try higher voltages later.....

Orthosing? Nah, already used this word since dunno when....

Don't forget that most, if not all, P35 mobos are supposed to support the upcoming Intel 45nm CPUs e.g. penryn. That's the reason I got this mobo. Another reason why I got the E6750 instead of the E6850/Q6600. Planning to go for the penryn family of CPUs in the future.....

Aaaa.... orthos 3 sec then already error? That's not stable la. For me, at least 6-12 hours of orthos before I even consider it "at least" stable.

Still waiting for my xigmatek before I OC further as my core temp is already about 55'c on stock heatsink at 3.28Ghz at 1.35v. (using easytuner5, not using core temp as it shows 6'c lower temperature)

How high did you set your vMCH and vFSB?

A higher vMCH will enable you to go higher on your bus speed. However, I'm not too sure about vFSB as some people claims that it doesn't do anything. Maybe a +0.1v just to make the system more stable???

I noticed you set your rams at 4-4-4-9 at 430Mhz. Was your rams at this setting when you increase the bus speed to 450Mhz? If so, it could be because of your rams. In that case, either loosen the timings, or reduce the ram speed. Alternatively, you need to find the max ram speed at each setting first before you OC your CPU.

I'm not at home to test out my DS3 but I think the TRD option is hidden. In the main bios menu, just press Ctrl + F1, then go into the section for overclocking.

Try to read up on guides to overclocking the C2D.

It is advisable to find the limit of each component before you OC your whole rig. By this, I mean you have to find the max OC for your CPU, RAM and mobo(FSB) separately.

There are a lot of guides that teaches you on how to OC your CPU while taking the RAMs and FSB out of the equation. Also vice versa on the RAMS and mobo. Once you know the limit of each component, then it is easier to OC your whole rig while bearing in mind the limit of each component.

Exactly. That's why in the world of OC, you need to find out the max OC for each component.

tRD = tRAS = tRA = Row Active Delay. It is a RAM sub-timing setting, usually quoted as the 4th parameter i.e. 3-3-3-9

Wow! This is the first time I've seen a mobo that cannot change vcore. Looks like it's true. Look here : http://global.msi.com.tw/index.php?func=pr...no=170&cat3_no=

Did you try any other software like Rightmark CPU clock?

Errr... I don't think it is stable. Look at the cache readings - L1 Trace is showing "12 Kuops"???

You need to stress your rig to see whether it is stable or not. Some stress programs are Orthos and OCCT.....

OIC, maybe get a new mobo?

Finally had a chance to test out my new rig.

On my P35-DS3, I'm stuck at 475mhz bus speed. This is at stock voltages for everything including vMCH.

No matter what I do, increase the vMCH, vFSB, vPCI-E, my mobo would hang at 480Mhz. I even tried jumping directly to 500Mhz but not successful!

Any ideas how to overcome this 480mhz wall? Or is it my CPU wall?

Ya. I did touch my NB heatsink. Not burning la, just feels warm. (Oh ya, my rig is naked! No casing.....)

I was googling around and found that the E6x50 series may have a CPU fsb wall of 490Mhz. Could be because of this reason. Anyway, will have to wait for my new CPU heatsink first, I guess.

No. I didn't remove the NB.

OIC, you're using the S3L. Mine is DS3. Slightly larger heatsink, but nothing compared to DQ6!!!! See pic.

Errr... but you have the P965-DS3 mobo wor.... Can't you lower the rams from 800Mhz to 667Mhz? That should be possible, because if not, how does this mobo support DDR2-667?

I never used the P965 before but maybe you can ask in the P965 thread on how to set the rams.

If that is not possible, there's 2 alternatives:
1) As kuchingfight suggested, loosen your rams to 5-5-5-15 or even higher e.g. 5-6-6-18
2) Find the maximum ram speed. That way, if you max ram speed is 500mhz (i.e. DDR2 1000mhz), then at least you know that you are nearing your limit if your bus speed is nearing the limit for the rams....

Yeah, no wall meh? My CPU has hit the wall so many times, dunno how many bruises adi....

Once hit 480Mhz, straight reboot.... Will try higher vcore later once my new heatsink comes....
