Hi All,

I am a neebee to this site and after looking at various other forums i thought that this site had more helpfull support regarding computer problems. Well here is my first post and no doubt it won't be my last...

I have a AsRock ConRoe945G-DVI motherboard and have just purchased an "Inte E6750 Core 2 Duo BX80557E6750 - 1333FSB - SKT 775 CPU". The manufacturers site says it doesn't support the 1333 FSB. My question is....can this CPU run on theis motherboard at the lower 1066 FSB?

Any help would be appreciated

Stuart

Yes it should be able to. It's highly unlikely that it wont.

Thanks Roz for your speedy reply. I got an email from AsRock support to which the details were vauge to say the least and he replied that if i install the CPU the pc will not boot!!!

The CPU support list from AsRock stated that an E6700, E6800 or extreme processor will support my motherboard but i thought the E6750 although it's 1333 FSB would still be ok to run on my motherboard as to get the 1333 FSB it requires to be overclocked to achieve this.

Can a CPU be a straight 1333 FSB or is it like my current E6300 which can be overclocked by using high grade DDR2 667 memory to achieve the 1066 FSB. Why do you think AsRock are not sure but like yourself i think it will

Best Regards

Stuarty

You have two primary issues

In order to save money, ASRock have selected the i945 chipset, which was not originally designed to support Core 2 processors. While it is technically possible to get Core 2 support due to the i945's Pentium Extreme Edition support of 1066 MHz FSB (1333 Mhz was never supported so forget about it), the biggest limitation is the power design. Since AsRock motherboards have very cheap power circuit designs, support of new Core 2 processors as they're released is not guaranteed. Furthermore, if they don't add BIOS support, you might be faced with a no-boot situation.

Your second issue is, even if you could get a Core 2 Duo E6750 to run at 1066 MHz FSB0, due to the core ratio of 8, what you'd have on your hands is a Core 2 Duo E6400.

Thanks Syphus for your detailed reply and now i understand a bit more than previously. It looks like i would be better going for the AsRock Conroe1333-eSATA2 or the Conroe1333 DVI/H R2.0 to which this CPU is more suited.

If you or anyone else has a better choice of motherboard for this CPU i would greatly appreciate it as i don't want to make the same mistake twice. I know i have illustrated the motherboards as AsRock but i have no knowledge of any other supporting motherboards.

Thanks Again

If you want some good advice, steer the hell away from ASRock, especially if you plan to couple it with a half decent CPU.

ASRock cheap out wherever possible; in the areas that most people don't realise are really important, such as power design, capacitor quality, chipset & mosfet cooling.

You're basically trading away stability and longevity.

I thought you had already purchased that ASrock board?

How much are you willing to spend on a new motherboard? Intel's P35 chipset is worth looking at, perhaps from Asus.

Hi Guy's

Yes i did purchase the motheorboard but i am able to send it back minus the postage which never amounted to much. The Conroe motherboard i was looking at will cost in the region of £64 and was looking for something possibly in that region.

The ball part of it is that i am building a budget pc in the short term to which i hope to upgrade the motherboard at a later time as my time is limited with my computer as i have other commitments ( New addition to family ) so i am looking for one that will work with the CPU for the short term. The reason i related AsRock is that i currently have an Core 2 Duo E6300 on a AsRock ConRoe945G-DVI motherboard to which i have had for the past 18 months with no problems on the type of stuff i do. I purchased the same motherboard again for my son as i was happy with my current system but decided to upgrade the CPU hense the reason for getting the right motherboard for my new CPU as it would be cheaper to change the motherboard rather than sending the CPU back. well so i thought

Would it be possible if one of you would recommend a particular motherboard that you would use with my new CPU? or some links?

Much appreciated

Stuarty

Well, it's never a good idea to skimp on the motherboard, IMO you would've been fine with a slightly cheaper cpu and a better motherboard, it's easier to upgrade a cpu than have to take nearly everything out to change the motherboard. A motherboard is like the foundation of a pc, and without a decent foundation, expect poorer performance and even lack of compatibility with newer components like pairing the E6750 with an old chipset that has no real native support of conroe.

Nearest to that price with the P35 chipset are Asus P5K SE Intel P35 (Socket 775) PCI-Express DDR2 Motherboard

Abit IP35-E (Socket 775) PCI-Express DDR2 Motherboard

I reccomend Asus from personal experience, i have never had a problem with them myself. I have heard mixxed views of Abit though, although i have also had an Abit board before and again not had a problem with them either.

Thanks for all you expert opinions and i will take it on board and look for a better motherboard. Just one more question regarding the CPU...Say i bought the ASUS P5K motherboard which supports 1333 FSB in overclocking mode? what does this mean? can the CPU run on this motherboard whithout the requirements of overclocking as i am looking to install components without tweaking the bios etc, like plug and play

Stuarty

Where does it say that?

Sorry my mistake, i was looking at the bios update settings on the mnf website. Appologies

Stuarty

After much help and suggestions i have found a motherboard that would complete all my needs for now and future upgrades. Bearing in mind i am not a heavy gamer or wanting high end computers but i think this will do.

Processor :

Intel Core 2 DUO E6750 CPU (2 x 2.66 GHz) 4MB Cache 1333FSB Socket LGA775

Motherboard:

GigaByte: GA-P35-DS3R for £74.75

GigaByte: GA-N650SLI-DS4 for £72.82

Would this be a good partnership and be stable without cutting costs?

Stuarty

Go for the top one, the p35 chipset. Anyone know anything about gigabyte boards?

Gigabyte are pretty similar quality to ASUS. Like ASUS, Gigabyte also has a subsidiary ("Axper"), through which the most budget boards are sold. This way they can supply product at every market point and retain reasonably good reputation with the Gigabyte brand.

Only problem with Gigabyte I've noticed is the poor translations throughout the marketing material, boxes, manuals and BIOS. It's also not uncommon for them to mention features on their boxes and in manuals that are not available with that particular product (they were selling PCI Express motherboards with an "AGP Pin" retention mechanism for quite some time back in 2004).

ASUS always seems just that little bit better.

Ty for the info.
